Electrically operated vehicle with a driver saddle

p00001The present invention relates to a vehicle fitted with a driver's seat and a vehicle frame that has two frame profiles that extend to a steering block and are separated from each other, where the vehicle has at least a front wheel mounted on a front wheel bracket of the vehicle frame and at least one rear wheel mounted on a rear wheel bracket, and the vehicle has an electric drive motor, as well as an electric energy storage device and a drive motor control device, and a kinematic chain and the storage device are provided between the drive motor and a driving wheel. Power can be arranged between the profiles of the frame, above the drive motor.

p00002The mentioned vehicle can be a two-wheeled vehicle with a front wheel and a rear wheel, or it can also be a vehicle with more than two wheels, with a front wheel and two rear wheels or two front wheels and a rear wheel.

p00003The vehicle has an electric drive motor for the advance which therefore does not produce combustion exhaust gases in any way. The drive energy is extracted from an electric energy storage device, and the drive motor control device serves to supply the drive electric motor with the electrical power necessary to the corresponding use case, from the storage device of Energy.

This already known motorcycle has an electric drive motor whose driving torque is transmitted by means of a connection axle to the rear wheel of said known motorcycle. An energy storage device, in the form of batteries, is arranged on top of the drive motor, with separation from the drive unit, which has the electric drive motor.

p00005From JP 05 065 085 A a motorcycle with electric drive has been disclosed which has an electric drive motor that transfers the driving torque to the rear wheel by means of a drive chain. The electrical energy storage device, in the form of batteries, is disposed between two box-shaped frame profiles, above the electric drive motor and with some separation from it.

The battery is arranged above the drive motor with separation from it. Based on this document, an embodiment has also been disclosed with batteries above and also below the drive motor that transfer their drive energy by means of a kinematic drive chain with a primary drive and a secondary drive to the rear wheel of the motorcycle. The primary drive consists of a CVT drive that can vary the transmission ratio continuously, and correspondingly has a pair of conical discs on the drive motor shaft and also on the input side of the gearbox, which can be connected by the input shaft side of the gearbox by means of a centrifugal clutch for torque transmission.

p00008From DE 603 ​​00 636 T2 an electric vehicle has been disclosed which has a group of batteries that can be fixed on a support of the vehicle seat.

p00012Electric-powered motorcycles, such as those described, have a device for

p00013Energy storage that must be recharged regularly. For this, the energy storage device is connected to a charging device or the like, so that as an alternative, it is foreseen to change the energy storage device discharged by a newly charged device or by an energy storage device that It still has enough capacity.

p00014In known motorcycles, an electrical conduction connection between the drive unit and the energy storage device must also be constituted, in the form of a connection cable, and then, the discharged energy storage device must be disassembled from the motorcycle with the help of tools and the new energy storage device must be mounted on the motorcycle again with the aid of tools and finally the electrical conduction connection between the power unit must be constituted drive and energy storage device.

p00015This process requires time and a lot of work. In addition, the existence of an electrical conduction connection in the form of a cable between the energy storage device and the drive unit also leads to the appearance of a safety and service risk. A pole protection can be provided by an encoded male-female connection unit; however, a free or freely accessible electric conduction constitutes a potential risk, since in powerful motorcycles there are high values ​​of the voltage and current between the drive unit and the energy storage device.

p00016In a motorcycle with electric drive, also intended for travel on unconsolidated terrain, there is also the possibility that the motorcycle unexpectedly comes into contact with the ground after a fall or after one of the motorcycle's wheels slips, and therefore the danger of breakdowns of the electrical connection conduction between the drive unit and the energy storage device occurs.

p00017Also, known motorcycles have a complex kinematic chain. To achieve the corresponding drive power, the electric motor must allow relatively high rotational speeds, which must be reduced in the primary drive of the kinematic chain. With this objective, a CVT gearbox as a primary drive is envisaged on the motorcycle already known today. It is also known to have instead a CVT gearbox, a chain drive as the primary drive. Both indicated solutions have drawbacks, since especially in the longitudinal direction of the primary drive, they have a high need for space, because of the traction means that takes the form of a belt or a chain. Likewise, this primary drive leads to the drawback, in the dynamics of the vehicle provided with it, that longitudinal vibrations can occur in the primary drive, which consume drive energy, in the traction means, said vibrations also having a negative acoustic effect. ; and the increased space requirement of the traction means also leads to the increase of the weight of the primary drive and, therefore, of the weight of the vehicle as a whole, which is contrary to the desired dynamic characteristics of the vehicle.

p00018From this background, the present invention aims to eliminate the indicated drawbacks, by configuring the vehicle in such a way that there are no free connection conductors between the energy storage device and the drive chain, and that the drive chain of the vehicle has lower power losses than in known electric drive vehicles, of the type indicated.

p00019The present invention provides for the solution of this objective the characteristics indicated in claim 1. Advantageous arrangements are described in the dependent claims.

p00020The invention provides a vehicle with a driver's seat and a vehicle frame that has two frame rails that extend to a steering block, spaced apart from each other; and the vehicle has at least one front wheel mounted on a support of the front wheel of the vehicle frame and at least one rear wheel mounted on a support of the rear wheel and the vehicle is provided with an electric drive motor , as well as an electrical energy storage device and a drive motor control device and a kinematic chain between the drive motor and a driving wheel, and the energy storage device can be arranged between the profiles of the frame above the drive motor, so that the energy storage device can be detachably attached to a drive unit that receives the drive motor.

p00021In this way, an electric drive vehicle is achieved by the invention, in which an electrically conductive connection between the energy storage device and the drive unit is formed by the arrangement of the energy storage device on the drive unit. or the drive motor, and this takes place automatically in the assembly of the energy storage device on the drive unit, without the user having to connect a cable connection with male and female connector between the energy storage device and the drive unit. If the user disassembles the energy storage device from the drive unit, it also interrupts the electrical conduction connection between the energy storage device and the power unit.

p00022drive, so that the electrical conduction connection will be interrupted before the conductive electrical contacts between the energy storage device and the drive unit are accessible from the outside. In the reverse assembly of an energy storage device on the drive unit, the electrical conduction connection will be made automatically with the assembly of the energy storage device on the drive unit, so that for this purpose, it can be provided in the energy storage device and in the drive unit, for example, socket projections with complementary surfaces and complementary shape or the like, which only allow the arrangement of the energy storage device on the drive unit in a single mounting position, and the electrical conduction connection between the energy storage device and the drive unit will be achieved only when the electrical conduction contacts in the energy storage device and in the drive unit they are no longer freely accessible to the user.

p00023In this way, a quick-change system is achieved simultaneously, since the user should not worry about the electrical conduction connection between the energy storage device and the drive unit, since this has already been carried out automatically and in a manner forced, without the user having to take specific actions for it.

p00024The vehicle object of the invention consists, for example, of an all-terrain motorcycle that is intended for sports trips on unconsolidated terrain or for competition purposes, so that the configuration of the arrangement of the energy storage device between the profiles of the frame also leads to that in the event of an unexpected fall of the driver with his vehicle, The energy storage device is protected by the profiles of the frame against damage caused by soil stones or the like. As for the profiles of the frame, they can be hollow profiles of closed or open type that can be constructed with a circular, oval, or box shape, and that extend to the steering block of the vehicle. The steering block features steering block bearings or steering bearings, which receive a front wheel support tiltingly in the vehicle.

p00025In addition, the arrangement of the drive unit and the energy storage device within the frame profiles of the vehicle, according to the invention, also allows the vehicle to have very favorable driving and handling characteristics. A configuration is thus achieved with the center of gravity of the vehicle below the driver's seat within a reception space constituted by the profiles of the frame. If the driver is sitting in the saddle in a normal position, approximately in the space of the lowest seat point, which takes the form of a cavity, the driver meets his center of body gravity, considered with respect to the surface on which the vehicle circulates, in a vertical line above the center of gravity of the vehicle, so that with the vehicle object of the invention, dynamic driving movements are possible around the vertical axis that passes through the center of gravity of the vehicle with reduced moments of inertial forces around this vertical axis. The drive unit is arranged, taking into account the direction of travel of the vehicle, before the housing for the rear wheel support of the vehicle.

p00026According to a further embodiment of the invention, a male-female connection is provided on the drive unit and the energy storage device which, when fixing the energy storage device on the drive unit, produces the electrical conduction connection . The fixing of the energy storage device on the drive unit can take place during the arrangement of the energy storage device on the drive unit by means of a connection of interlocking projections as already explained, or by another connection of fast type and, in this way, the electrical conduction connection is also produced. Also, at the time of fixing, a process can be carried out in which the energy storage device is arranged on the drive device, but the electrical conduction connection is achieved, for example, only with the interlocking between the energy storage device and the drive unit.

p00027According to a further embodiment of the invention, it is envisioned that the drive unit has a first casing body that receives the drive motor and a gearbox, so that the side of the casing body directed towards the energy storage device has a male connector or a female connector for electrical connection with the energy storage device. A second enclosure body can be provided that supports the energy storage device, so that on the side of the enclosure body directed to the drive unit, a male or female connector is arranged for the electrical connection with the drive unit. This means, in other words, that a male connector is arranged in the first enclosure and a female connector in the second enclosure or a female connector in the first enclosure and a male connector in the second enclosure to achieve contact Safe electrical between the energy storage device and the drive unit when available

p00028or the energy storage device is fixed on the drive unit. When disassembling the energy storage device with respect to the drive unit, the electrical conduction connection between said elements is separated before the electrical contacts are accessible to the user. The energy storage device may be provided with a device that puts the electrical contacts provided therein without tension as soon as the physical connection between the device is separated.

p00029Energy storage and drive unit.

p00030According to a further embodiment of the invention, the drive unit is provided to have a housing for the arrangement of the rear wheel support of the vehicle. The embodiment of the rear wheel support may comprise, for example, swingarms of the rear wheel that allow the rear wheel assembly of the vehicle, presenting a pivot pivot point that is located within the first enclosure body of the vehicle unit. drive This leads to a compact construction of the vehicle of the invention.

p00031According to a further embodiment of the invention, it is also provided that the drive motor control device is arranged in the drive unit. The drive motor control device may therefore be arranged in the first enclosure, and therefore, is not accessible to the vehicle user, so that the unexpected contact of the vehicle user with components that can be avoided They carry current. Also, this configuration further leads to the fact that the first housing can be arranged for cooling the drive motor and the control device of the drive motor and that the heating parts of the housing take the form of cooling fins and the like being arranged in an area of ​​the vehicle that, on the one hand, is in the flow of the cooling air of the vehicle, and on the other, are protected against dirt, and that with proper use of the vehicle does not come into contact with the user of the vehicle.

p00032In order to achieve a rapid change of an energy storage device discharged or substantially discharged by a fully charged or sufficiently charged energy storage device, it is provided, according to a further embodiment of the invention, that the energy storage device and the drive unit can be connected by means of an electrical conduction connection of the energy storage device and the drive motor with a quick coupling without the aid of tools, achieving said electrical conduction connection. The quick coupling can be an interlocking coupling, a self-locking coupling, a tightening coupling or the like, which have, for example, forced guiding elements in the energy storage device and in the drive unit, so that the device Energy storage can only be mounted on the drive unit in a single place, and the quick coupling engages itself in the assembly of the energy storage device on the drive unit, simultaneously forming an electrical conduction connection between the energy storage device and the drive motor.

p00033According to another additional embodiment of the invention, it is also provided that in the first housing a connection device is provided for the connection of a charging device for the supply of electric energy to the energy storage device. This connection device can be arranged, for example, on the first enclosure, above an area where dirt projected from the driving wheel in the form of mud, stones, or the like can reach. The invention also provides, however, that instead of this assembly or additionally, a connection device for connecting the loading device is arranged on the second housing. In this way, it is possible that the user of the vehicle object of the invention, for example, at the end of the day, separates the energy storage device from the second enclosure body of the drive unit and can load the storage device from energy separately from the vehicle. In this way, the energy storage device can be charged both in the vehicle and separately with respect to the vehicle.

p00034According to a further embodiment of the invention, the kinematic chain is provided to have a primary drive free of traction element between a power shaft of the drive motor and a power shaft of the drive unit.

p00035This configuration allows a lower need for primary drive space and, therefore, facilitates a very dynamic vehicle and the disappearance of a complex gearbox affected by losses, as is the case, for example, in a gearbox of type Continuous equipped with a belt as a traction element, between the power axis of the electric drive motor and the input shaft of a gearbox.

p00036According to a further embodiment of the invention, it is envisioned that the primary drive has a one-piece intermediate wheel that has two teeth, in which the first gear meshes with a gear shaft of the drive motor power shaft, and whose second gear gears with the toothing of the power axis of the drive unit. In this way, the invention achieves an extraordinarily space-saving configuration in the primary drive, since both teeth have been provided in the intermediate gearwheel with axial separation from each other. The longitudinal axis of the intermediate wheel runs parallel to the longitudinal axis of the power axis of the electric drive motor and parallel to the power axis of the drive unit. This allows an extraordinarily favorable construction, due to the reduction of space and the reduction of costs, since the centrifugal clutch that exists in the electric motorcycles described above can be dispensed with, and there is no means of traction that would increase significantly The need for space.

p00037According to a further development of the invention, it is envisioned that the kinematic chain between the power axis of the drive unit and a driving wheel has a traction device. As for the traction device, this can consist of a chain or a belt, and as for the driving wheel it can be, for example, the rear wheel of an electrically driven two-wheeled motorcycle, in accordance with the present invention.

p000385 According to a further development of the invention, it is provided that the drive unit is provided, at least in the space of the drive motor, with cooling fins and the control device of the drive motor is provided with cooling fins arranged in the longitudinal direction of the drive unit, and that there is a section with cooling fins in the vertical direction in the drive motor control space, presenting a housing for the arrangement of the rear wheel support, and which is crossed by the power axis of the drive unit. Instead of the cooling fins that run longitudinally, or additionally thereto, cooling fins that run radially, which effect cooling of the drive unit, can also be provided.

p00039In this way, the drive unit presents in the space of the engine control device of

p00040fifteen drive cooling fins that run vertically, which are open both up and down, and constitute a block of cooling fins in which a transverse hole is formed with respect to the longitudinal direction of the drive unit, which can be crossed by an axle with which the aforementioned rear wheel support can be mounted on said block of cooling fins. In this way, an integration of functions that saves space is achieved, since in this way, no independent joining surface for the rear wheel tilting arms should be arranged in the vehicle frame.

p00041According to a further development of the invention, it is envisioned that the drive unit has a reception space to receive the drive motor, provided with a cover, and that the drive motor can be mounted on the cover by means of a bearing bearing, and that the lid be equipped with cooling fins. In this way, a configuration is achieved with which, for example, according to the box construction system different vehicles with different powers are possible, in accordance with the present invention. In this way, the drive motor can be changed in a simple way, for example, by another drive motor of greater power, since after dismantling the cover and dismantling a cogwheel that is engaged with the intermediate wheel in the power axis of the electric drive motor, this can be removed from the first enclosure body of the drive unit and changed, for example, by a higher power drive motor. This may occur, according to an advantageous embodiment of the present invention, even for the drive unit mounted on the vehicle frame. Since the energy storage device can be detachably attached to the drive unit, it can be

p0004235 Easily disassembled from the drive unit and can be exchanged for an energy storage device that can have, for example, a larger number of battery cells. In this way, a vehicle according to the invention would be available with greater power.

p00043Finally, according to the present invention, it is also provided that the vehicle according to the invention consists of a two-wheeled vehicle having only one front wheel and one rear wheel, and that the drive unit is arranged between the profiles of the frame below the energy storage device, and that the vehicle has a steering device functionally coupled with the front wheel support, and that the rear wheel is mounted with tilting arms, which are mounted on the drive unit. This two-wheeled vehicle, according to the invention, can also be a motorcycle that is

p00044Four. Five equipped, for example, for its operation also outside consolidated circulation tracks, with significant displacements of the docks, so that it is appropriate for sporting purposes abroad.

p00045In this vehicle according to the invention, the energy storage device is located below the driver's seat and is also protected by the laterally running frame profiles, so that the energy storage device is protected even for demanding use outside. of tracks against a possible fall in unconsolidated terrain, avoiding damage. This vehicle may be equipped, in addition to the already mounted energy storage device, with a second energy storage device that can be changed in a very short time, replacing the first energy storage device that may have been discharged after a further route. long.

p0004655 For this, it is only necessary to disassemble the driver's seat that is coupled, for example, with an interlocking or quick fixing connection with the vehicle frame, so that the driver's seat can also be disassembled without the help of tools. After mounting the driver's seat, the energy storage device is freely accessible from above and can be disassembled without the help of tools taking it out of the space of the frame, between the profiles of the same. The placement of the second energy storage device sufficiently charged between both frame profiles and the attachment to the drive unit allows the electrical conduction connection between the drive unit and the energy storage device to be achieved without the aid of tools . After placement and, for example, locking the driver's seat in the vehicle frame, it will be

p0004765 It is prepared for immediate use.

p00048During operation with the second energy storage device, the first energy storage device can be recharged, so that after the discharge of the second energy storage device, the first one is again in a fully charged state, so that that the duration of use of the vehicle according to the invention is unlimited.

p000495 The invention will be explained in more detail below based on the drawings. In the drawings:

p00050Figure 1 shows a side view of a vehicle according to an embodiment according to the present invention.

p00051Figure 2 shows a view of the vehicle according to figure 1 in which some parts have been disassembled.

p00052Figure 3 shows a representation of the vehicle, according to Figure 2, from above.

p00053fifteen Figure 4A shows a larger scale representation of the vehicle drive unit according to Figure 1 with the energy storage device disposed therein.

p00054Figure 4B is a representation similar to Figure 4A with a connection device provided in the energy storage device for the connection of a charging device, and

p00055Figure 5 shows a sectional view of the drive unit according to Figure 4, along the line VV.

p00056The vehicle 1 shown in Figure 1 of the drawings consists of a two-wheeled vehicle in the form of a motorcycle, which is intended for circulation on both consolidated roads and on non-land

p0005725 consolidated.

p00058The vehicle 1 has a front wheel bracket 2 constructed in the form of a front wheel fork, the front wheel 3 rotatably mounted, which can be braked by the brake disc 4 and a braking group that has not been shown. The support 2 of the front wheel is rotatable at a certain angle of rotation in a steering head 5 or steering block in which it is mounted. By means of a steering device in the form of a handlebar 6, the support 2 of the front wheel can be forced to rotate by the action of the driver, who can be seated on the saddle 7.

p00059The driver's seat 7, as well as the side cover pieces 8 and a rear frame group 9, can

p0006035 be detachably fixed on a frame 10 of the vehicle, which is constituted by several profiles of the frame.

p00061As directly visible from Figure 2 of the drawings, which shows a side view of the motorcycle shown in Figure 1 of the drawings, in which the covering parts 8 and the rear frame group 9 have been disassembled , the frame 10 has among other elements (see also figure 3) two frame profiles 11, which from a lower triangle of the frame 12, on which the support 13 of the rear wheel in the form of a tilting arm swings, they extend separately from each other to the steering block 5, which in the embodiment shown is constituted by a tube 14 of the steering block, and because of their arrangement with separation from each other they constitute between them a reception space 15 in which can be arranged a device

p00062Four. Five energy storage 16, which is visible in figure 4 of the drawings.

p00063The frame profiles 11 can be hollow profiles of closed or open section that have a low weight and high rigidity, and given their arrangement with separation from each other, can receive the energy storage device 16 which, therefore, in the case from a possible fall of the vehicle 1, it is well protected against damage.

p00064In the rear wheel support or the tilting arms 13, a rear wheel 17 is mounted with the ability to turn which, in addition to a brake disc 18, has a chain sprocket 19, in which a means of traction, not shown in detail, in the form of a chain, which is coupled with a chain sprocket 20 and by which the vehicle 1 can be started.

p0006555 As is also visible in Figure 2, the swinging arms 13 are supported by a spring device 21 having an adjustable spring 22 and an equally adjustable shock absorber 23, on the support 24 of the vehicle frame 10, which in turn supports through frame profiles 25 in frame profiles 11.

p00066The frame profiles 25 therefore run between the frame profiles 11 and the support 24, which is constructed by two tubes arranged substantially vertically upwards from the frame triangle 12, which together with the frame profiles 11, which They run upward from the triangle of the frame 12 in the direction of the steering tube 14, form the receiving space 15 to receive the energy storage device 16.

p0006765 The frame 10 of the vehicle further comprises two other frame profiles in the form of lower stringers 26,

p00068which extend substantially from the triangle 12 of the frame inclined in the direction of the steering tube 14, such that they run from the triangle 12 of the frame initially substantially horizontally. They then run similarly to an "S" to the steering tube 14.

p00069These stringers 26 together with the other frame profiles, which have indicated a reception space 27 for a drive unit 28 visible based on Figure 4 of the drawings.

p00070The drive unit 28 has a first casing body 29, in which a drive motor 30 and a gearbox 31 are mounted, which is visible in more detail in Figure 5 of the drawings.

p00071The first enclosure body 29 has on its upper face, a connection surface 32 for receiving the energy storage device 16. The energy storage device 16 has a second enclosure 33, on which a series of rechargeable batteries is arranged . The arrangement of the energy storage device 16 on the drive unit 28 takes place in such a way that with the fixing of the energy storage device 16 on the drive unit 28, an electrical conduction connection is formed between the storage device of energy 16 and drive unit 28, without the user of the vehicle 1 being able to make contact with electrically stressed parts of the combination formed by the drive unit 28 and the energy storage device 16.

p00072For this purpose, on the connection surface 32 and a complementary connection surface 34 of the energy storage device 16, a quick coupling device is provided that has lockable or lockable construction elements, or that can be held or locked autonomously , which allow the arrangement of the energy storage device 16 on the drive unit 28 to form a preferably coupling connection between the first housing 29 and the second housing 33, and that this connection can be carried out without tools

p00073If the energy storage device 16 is placed on the drive unit 28, an electrical conduction connection will be formed simultaneously between the energy storage device 16 and the drive unit 28; For this purpose, a male-female connection 35 between the energy storage device 16 and the drive unit 28 produces the electrical conduction connection.

p00074The male-female connection 35 of the embodiment shown is configured such that the first housing 29 has a circular bushing 60 with electrical contacts disposed therein, and the bushing 60 can be coupled with a connector 61 provided with surfaces complementary and constituted on the second enclosure 33, which has internal electrical contacts that can be coupled with the electrical contacts arranged in the bushing 60 physically, thus forming the electrical conduction connection between the energy storage device 16 and the drive unit 28, without the need for a cable connection. The male-female connection 35 is therefore simultaneously a quick coupling between the energy storage device 16 and the drive unit 28, which serves to ensure the position of the energy storage device 16 on the drive unit 28 , and that can be easily disassembled without using tools.

p00075In the final part of the first enclosure body 29, arranged in opposition to the male-female connection 35 is a connection device 36, by which the energy storage device 16 can be charged even in the state mounted on the vehicle 1, by a charging device.

p00076As is visible in Figure 4B of the drawings, it is also possible to provide, in the second enclosure body 33, a connection device 36 for the connection of a loading device. In this way, the user of the vehicle according to the invention can also carry out the charging of the energy storage device 16 when said device is not arranged in the vehicle. This is especially advantageous when the user wishes to charge the energy storage device 16 separately with respect to the vehicle, for example, during the night, or if an energy storage device 16 must be charged when another energy storage device 16 is It is mounted on the vehicle.

p00077The first enclosure body 29 has a circularly constructed lid 37, in which multiple longitudinally arranged cooling fins 38 are arranged and whose lid can be fixed by threaded bolts 39 to the first enclosure body 29. In the space below the connection device 36, there is in the first enclosure body 29 an area provided with longitudinally arranged cooling fins 40 which serve to cool a drive motor control device disposed in this area, within of the first enveloping body 29, and not shown in detail. The drive motor control device can be a device of the type equipped with electronic circuits for controlling the power of the electric drive motor 30, so that the user of the vehicle 1, by means of a drive device arranged in the handlebar 6 , controls the drive energy fed to the electric drive motor 30 from the energy storage device 16.

p00078The first enclosure body 29 is provided with a support 42 for the arrangement of an arm mounting shaft

p00079swingarms 13 in the first enclosure 29.

p00080As can be seen in greater detail in Figure 5 of the drawings, the housing 42 runs through a block 44 of the housing provided with vertical cooling fins 43, which is arranged under the space provided with longitudinal cooling fins 40, so that these cooling fins 43 also serve for cooling the drive motor control device, located inside the first casing body 29 and below the longitudinally running cooling fins 40.

p00081The electric drive motor 30 disposed within the first enclosure 29, in a reception space 45 constituted therein, can consist of a brushless direct current motor, which has a stator 46 mounted in the reception space 45 and a rotor 47, which is integrally engaged in rotation with the axis of rotor 48, which is mounted on the first casing body 29 by means of a bearing bearing 49 and an additional bearing bearing 50 arranged in the cover 37. It is also possible that the drive motor consists of a self-excited alternating current motor or with external excitation.

p00082The kinematic chain 51 has a single-stage primary drive 52, without traction device between the rotor shaft or the power shaft 48 of the electric drive motor 30 and a power shaft 53 of the drive unit 28.

p00083On the power shaft 53, mounted with rotation capacity in the first enclosure body 29, the chain sprocket 20, which has already been explained, is fixed in rotation and, at the opposite end to the chain sprocket 20, a cogwheel 54 provided with a toothed 55 is fixed in rotation.

p00084The cogwheel 54 is engaged with an intermediate cogwheel 56, which is constituted as a double cogwheel, and which has two cogwheels 57, 58.

p00085The first gear 57 has a smaller base circle than the second gear 58, and is engaged with the gear wheel 54 fixed in rotation with the power shaft 53. The second gear 58 is engaged with the gear wheel fixed 59 in rotation on the rotor shaft 48, so that the rotation speed of the rotor shaft 48 is reduced through the double teeth or intermediate wheel 56 towards the power shaft 53.

p00086This primary drive without a single-stage traction element, with the double gearwheel 56 has, compared to a gearbox by chain or with a continuous CVT gearbox equipped with drive belts, a significantly better performance in the torque transfer from drive motor 30 to power shaft 53.

p00087Furthermore, by means of the intermediate wheel 56, in comparison with the boxes already explained provided with a traction means, a sensible space saving can be achieved, since in this way, the horizontal separation "h" between the middle part of the axis of power 53 is significantly reduced. Likewise, the operation of the primary drive with the double teeth 56 is acoustically quieter than the primary drive that operates with a traction means.

p00088As is especially apparent from Figure 1 and Figure 2 and also from Figure 3 of the drawings, the energy storage device 16 is located in the reception space 15 between the profiles of the frame 11 and 25. If the driver of the vehicle 1 verifies that the charge capacity of the batteries of the energy storage device 16 has significantly decreased, he can charge the energy storage device by means of the connection device 36 with a charging apparatus, to recharge the batteries. Alternatively, it is also possible, with reduced manual handling, to exchange the discharged energy storage device with an energy storage device that has sufficient load capacity.

p00089For this, it is only necessary to disassemble the driver's seat 7 from the vehicle frame 10, which is coupled to the vehicle frame 10 with interlocking connections that can be released, for example, without tools, so that the storage device of energy 16, which is arranged in the reception space 15, It is freely accessible from the top and can also be disassembled from the drive unit 28 without tools, and can be removed from the reception space 15.

p00090A second energy storage device, with sufficient load capacity, can be guided from above into the reception space 15 and fixed to the drive unit 28 or to the connection surface 32 of the drive unit 28, Looking at this position. This process allows the electrical conduction connection between the second energy storage device and the drive unit 28 to be constituted, without it being necessary to disconnect a cable connection between the drive unit 28 and the energy storage device during the disassembly and reconnect the new energy storage device during assembly.

p00091By removing the spent energy storage device with used batteries, the electrical conduction connection will be released and by placing the energy storage device 16 with sufficient load capacity in the reception space 15 and fixing it on the power unit. drive 28 the electrical conduction connection between the energy storage device 16 and the drive unit 28 will be achieved immediately. Subsequently, it is only necessary to replace the saddle of the

p000925 driver and fix it, vehicle 1 being again in traveling conditions. Although it has now been explained that the driver's seat 7 is fixed only on the frame 10 of the vehicle, a detachable threaded connection between the driver's seat 7 and the frame 10 can also be provided, which has, for example, a threaded connection which can be disassembled without the use of tools in the form of a wing nut or a threaded connection that can be disassembled using standard tools.

p00093With respect to the features of the invention that have not been specifically explained in this description, reference will be made expressly to the claims and drawings.
