Motorcycle Fairing Structure of a Motorcycle Vehicle [Technical Field]

This invention relates to a fairing structure of a motorcycle type vehicle, mainly to a technology applied to lighten the tilt of turn at the time of the initial phase of the rotation of the body of a vehicle.

[Previous Technique]

Conventionally, a fairing structure as described in Patent Document 1 is well known as a fairing structure of a motorcycle type vehicle, for example. Referring to Patent Document 1 with reference to the numbers shown therein, this motorcycle-type vehicle fairing structure is of a type in which each side engine cover (50) covering the side surface of the front of a motorcycle has an opening (83) applied to lighten the tilt of turn at the time of the initial phase of the rotation of the body of a vehicle.

[Reference Document on Previous Technique] [Patent Document] [Patent Document 1] Patent Publication open for Inspection 2 5 Japanese Publication No. 2006-347343 [Summary of the Invention] [Problems to be solved by the Invention]

In the fairing structure of a motorcycle type vehicle of the prior art, the opening (83) of each cover (50) of the side engine has been formed laterally at a location of an internal structure (a radiator (36) and / or a unit (26a) of an engine cylinder, for example) of a vehicle.

For that reason, the internal structure has been responsible for the obstruction of the air flow that tends to pass through the opening (83), and as a consequence, it could not always be said that the inclination of turn at the time of the phase Initial rotation of the vehicle body is produced with the desired lightness. Therefore, it has been necessary that the opening (83) be enlarged in the fairing structure of the prior art, if an attempt has been made to improve the lightness of the turning inclination described above. The enlargement of the opening has made the internal structure easily exposed to the view through the opening (83), resulting in a fear of damage to the external appearance.

An objective of the present invention is to provide a fairing structure of a motorcycle type vehicle, more specifically, a fairing structure that allows less damage to the external appearance, while providing the improvement in the lightness of the turn inclination at the time of the initial phase of the rotation of the body of a vehicle.

[Means for solving the problem]

5 To solve the above problem, a fairing structure of a motorcycle type vehicle according to the present invention comprises a header tube mounted on the front part of a body frame, a steering mechanism that supports a rotationally front wheel, being so held at the same time with the header tube so that it is able to pivot about the axis of the header tube at the front of the header tube, side engine covers each disposed on the transverse outside of the body frame, and an opening formed on each side engine cover that communicates with the transverse inside and outside of each side engine cover, in which in side view, the side engine covers are elongated to the front of the header tube, and the opening is in a position such that it is level with the head tube and overlaps with the steering mechanism in the front part of the head tube.

According to the fairing structure of the motorcycle type vehicle of the present invention, the side engine covers are elongated to the front of the header tube in side view, thus allowing the straightening effect obtained with the side engine covers to increase .

In addition, the opening is in a position such that it is level with the head tube and overlaps with the steering mechanism on the front of the head tube in side view, thus allowing air flow to improve as it passes through of the opening. The steering mechanism is so attached to the header tube in such a way that it is able to pivot about the axis of the header tube in the front part of the

5 header, resulting in no obstacle to the movement of ί

pivoted of the steering mechanism in the front part of the header tube. In other words, it follows that a space that allows the pivoting movement of the steering mechanism in the front part of the header tube is secured. The opening according to the present invention is in a position that corresponds to this space, ο;

It is level with the head tube and overlaps with the steering mechanism in the front part of the head tube in side view, thus allowing the presence of space to improve the flow of air passing through the opening.

As a result of the improvement of the air flow that passes through

I î of the opening, the opening of the present invention can cause it to be)

I improve the lightness of the tilt of turn at the time of the initial phase ί

j of the rotation of the vehicle body without enlarging the opening!

I both like the opening (83) of the prior art. Consequently, a lower exposure to the internal structure is visible.

Specifically, it is understood that the fairing structure of the motorcycle type vehicle of the present invention also offers the advantage of allowing less damage to the external appearance, while facilitating the improvement in the lightness of the turn inclination at the time of the initial phase. of the turn of the vehicle body.

It is desirable to adopt an arrangement in which each side engine cover is in the form of an engine cover having an upper engine cover disposed in the upper part of the vehicle and a central motor cover arranged under the upper engine cover, in the that a

5 upper end of the central motor cover is located farther out in the transverse direction than a lower end of the upper motor cover, while the upper end of the central motor cover and the lower end of the upper motor cover are located such that they overlap each other in side view, in which with the opening formed in the upper engine cover, at least part of the opening is covered with the upper end of the central motor cover located remote in the transverse direction of the opening in side view.

The adoption of this arrangement makes it possible that at least part of the opening appears to be covered with the upper end of the cover of the central motor in side view, even when a large size opening is formed. Consequently, it is possible to achieve maximum improvement both in the previous lightness and in the external aspect.

It is more desirable to adopt an arrangement in which an inclination in decline farther out in the transverse direction of the body of the vehicle 15 with the distance closer to the upper part is formed in the upper part of the opening of the upper engine cover.

The adoption of this arrangement makes it possible for air to be admitted into the opening by taking advantage of the decline at the time of the vehicle's tilt, so that an area of ​​the opening can be effectively applied to improve the previous lightness, even when part of the opening is covered with the central motor cover.

It is also desirable to adopt an arrangement in which a blade having a top surface in the form of a sloping surface inclined more downward with the distance closest to the anterior part formed in the

5 front part of the opening.

<img file="AR080949A1_D0001.tif" />

The adoption of this provision makes it possible for the blade to increase the pressure on the ground of the previous wheel, and also that the lightness at the time of the initial phase of the rotation of the vehicle body is also improved from the point of seen in which the opening is located at the rear of the blade so that the adhesion of a running current to the surface of a motor cover is suppressed when it occurs behind the blade.

It is more desirable to adopt a provision in which the blade has on the transverse outside a projection that extends upward from the blade.

The adoption of this arrangement makes it possible for the running current to be controlled so that it flows in the longitudinal direction of the vehicle by applying the projection to suppress the phenomenon that the running current in the blade diffuses in the transverse direction, thus allowing the straightening effect on the shovel that is enhanced.

It is also desirable to adopt a provision in which a windshield is arranged in the front part of the steering mechanism, and the opening is exposed to the outside on the blade, in front view of the vehicle.

The adoption of this provision makes it possible for the running current that has been straightened with the blade to be driven to one side of the motorist taking advantage of the pivoting space of the steering mechanism, thus allowing not only that the protection effect of a motorist against the wind is enhanced with the windshield but also that gives an adequate degree of running current to the rider, allowing at the same time the suppression of a negative pressure generated behind the windshield.

[Completion of the Invention]

An embodiment of a fairing structure of a motorcycle vehicle according to the present invention will now be described with reference to the accompanying drawings.

Figure 1 is a front view of a motorcycle as an example of a motorcycle type vehicle that involves the use of a motorcycle type fairing structure according to the present invention. Figure 2 is a side view of the same as that of Figure 1. Figure 3 is an enlarged partial side view of the same as that of Figure 1. Figure 4 is a perspective view of the front part of a header tube of the same as Io of Figure 1, viewed from above obliquely. Figure 5 is a view from below of the front part of the same as Io of Figure 4. Figure 6 is a schematic side view of an example steering mechanism. Figure 7 is a view taken in the direction of an arrow b of Figure 6.

A motorcycle 1, as illustrated, has a body frame 10 that forms the body of a vehicle. The body frame 10 has a head tube 11 constituting an anterior end of the body frame 10, a main frame 12 extending backwards from the head tube 11, a pivoting plate 13 mounted at the rear of the frame 12 main, a seat rail 14 extending backwards from the pivoting plate 13 and the main frame 12, and a downward tube 15 extending downward in the direction from the head tube 11.

A steering mechanism ST is fastened in such a way with the header tube 11 which is able to pivot about the axis of the header tube 11 at the front of the incoming tube 11 e3.

A well-known basic structure can be applied to constitute the steering mechanism ST. As shown in Figures 6 and 7, for example, the steering mechanism ST may be of a structure in which a shaft tree 11s is pivotally supported on the head tube 11 to join an upper bridge 11t and a bridge 11b lower to the top and bottom of the tree 11s of stem, and a pair of front forks 11f are supported on the upper bridge 11t and the lower bridge 11b to fix a handlebar 11h (see Figure 1) to the upper bridge 11t and also to rotatably mount a wheel 1F anterior to the lower ends of the pair of previous 11f forks.

When the rider turns the handlebar 11 h, the steering mechanism ST of this type causes the previous wheel 1F to be turned clockwise or in the reverse direction in plan view by pivoting the upper bridge 11t, the bridge 11b bottom and the pair of anterior forks 11f around the shaft shaft 11s, that is, of the header tube 11 at the front of the header tube 11, making it possible to change a motorcycle ripping course 1.

A motor 16 is fixed to the main frame 12, the pivoting plate 13 and the descending tube 15.

The pivoting plate 13 is so tight with an oscillating arm 17 that it is capable of oscillating up and down through a pivot shaft 13p. The rear end of the oscillating arm 17 is provided with a rear wheel 1R specified as a driving wheel. The rear wheel 1R is driven by the engine 16.

The seat rail 14 has a seat 18 on top where the rider takes his position.

The front of the vehicle body is covered with a front engine cover and 30 and left engine covers.

The cover 20 of the previous motor is mounted on a tip (22) present in the form of a projection that extends forward from the head tube 11 as shown in Figures 4 and 5.

As shown in Figures 1 and 2, the cover 20 of the previous motor has a windshield 21 on top.

Each of the side engine covers 30 is disposed on the transverse exterior of the body frame 10 and is directly or indirectly fixed to the body frame 10 as described below. Each cover 30 of the lateral motors has an opening 41 that communicates with the transverse interior and exterior of each cover 30 of the lateral motor.

The main aspects of the present embodiment are that, in side view 5, the side engine covers 30 are elongated to the front of the header tube 11, and the opening 41 is in a position such that it is level with the tube 11 of head and overlaps with the steering mechanism ST in the front part of the head tube 11, as shown in figures 2 and 3. In other words, the opening 41 is in a position such that it overlaps with a pivoting region of the steering mechanism ST, in side view.

According to the fairing structure of the motorcycle type vehicle, as described above, the side engine covers 30 are elongated to the front of the header tube 11, in side view, thus enabling the straightening effect obtained with the covers 30 side engine is enhanced.

In addition, the opening 41 is in a position such that it is level with the head tube 11 and overlaps with the steering mechanism ST in the front part of the head tube 11, in side view, thus enabling the air flow that passes through the opening is made better.

The steering mechanism ST is held in such a way with the header tube 11 which is capable of pivoting about the axis of the header tube 11 in the front part of the header tube 11, which results in no obstacle to the Pivot movement of the ST mechanism of

5 direction in the front part of the header tube 11. In other words,

W it follows that a space is secured (the pivoting region) S which allows the pivoting movement of the steering mechanism ST in the front part of the header tube 11, as is also shown in Figure 4. The opening 41 according to the present embodiment, is in a position such that it corresponds to the space S, or is level with the head tube 11 and overlaps with the steering mechanism ST in the front part of the head tube 11, thus enabling the presence of the space S to improve the flow A1 (see Figure 1) of air passing through the opening

41.

As a consequence of the improvement of the air flow passing through the opening 41, the opening 41 of the present embodiment can improve the lightness of the turning inclination at the time of the initial phase of the rotation of the bodywork of the vehicle without enlarging the opening as much as the opening (83) of the prior art. Consequently, less exposure to the internal structure is visible (the previous 11f forks and the like in this case).

Specifically, it is understood that the fairing structure of the motorcycle type vehicle according to the present embodiment also allows less damage to the external appearance, while allowing the improvement in the lightness of the turn inclination at the time of the initial phase of the turn of the vehicle body.

In addition, in view of the fact that the head tube 11 is located in the upper part of the vehicle in the direction of the height, the opening 41 is assumed to be in this location, thus enabling the air passage A1 to be carried out at a location with great transverse rusting at the time of the tilt of the vehicle. Consequently, it is possible to facilitate further improvement in lightness.

It is noted that it has been necessary that in the fairing structure of the prior art the opening (83) be enlarged, if an attempt has been made to improve the lightness. The enlargement of the opening has made the internal structure easily exposed to the view through the opening (83), which results in difficulty in protecting the internal structure with the side engine covers (50). For that reason, it has been necessary to regulate the disposition of the internal structure and / or use a separate or similar cover for protection, if an attempt has been made to protect the internal structure. Consequently, in the fairing structure of the prior art there was a risk of making a reduction in the degree of freedom for the disposition of the internal structure and / or an increase in the number of parts.

On the contrary, the fairing structure of the present embodiment can facilitate the improvement in the lightness of the turning inclination at the time of the initial phase of the rotation of the body of the vehicle without enlarging the opening (41) as much as the opening (83) of the prior art and, therefore, may not give rise to any defect such as the previous one, which results in the increase in the degree of freedom of the internal structure and the elimination of the need to increase the number of parts as well.

Meanwhile, the opening (83) of the prior art adopts a shape that in its anterior part is open and, therefore, there is a risk of causing a reduction in the straightening effect obtained with the side engine covers.

On the contrary, the opening 41 of the present embodiment adopts a shape that in its front part is not open and, therefore, can cause the straightening effect obtained with the side engine covers to be maintained.

Each cover 30 of the side engine has a cover 40 of the upper engine arranged in the upper part of the vehicle and a cover 50 of the central motor arranged under the cover 40 of the upper engine.

Figure 8 is a side view of the cover 40 of the upper motor. Figure 9 is a pianta view of the upper motor cover of Figure 8. Figure 10 is a sectional view taken along line cc in of Figure 8. Figure 11 is a sectional view taken along the line dd of figure 8. Figure 12 is a side view of the cover 50 of the central motor. Figure 3 is a view of the right side of the central motor cover of Figure 12. Figure 14 is a sectional view taken along line cc of Figure 12. Figure 5 is a side view of the central motor cover of Figure 14.

As shown in these figures, as in Figures 1 and 3, according to the present embodiment, an upper end 52 of the cover 50 of the central motor is located farther out in the transverse direction than a lower end 42 of the cover 40 of the upper motor, while the lower end 42 of the upper motor cover 40 and the upper end 52 of the central motor cover 50 are positioned so that they overlap each other, in side view, as shown in Figure 3, in which with the opening 41 formed in the cover 40 of the upper motor, at least part (a part 41 or low extending parallel to an edge 41 b

Lower IV of the opening 41 in the present embodiment) of the opening 41 is covered with the upper end 52 of the central motor cover 50 located remote in the transverse direction of the opening 41.

The adoption of this arrangement makes it possible for the part (part 5 41 or lower, for example) of the opening 41 to appear to be covered with the upper end 52 of the central motor cover, even when the opening 41 is enlarged. Consequently, it is possible to satisfy both the external appearance and the additional improvement in lightness resulting from the enlargement of the opening 41.

At the upper part of the opening 41 of the cover 40 of the upper engine, an incline is inclined further outward in the transverse direction of the vehicle body with a distance closer to the top.

The adoption of this arrangement makes it possible for the air to be admitted into the opening 41, as shown by a leaflet A2 in the figure. 1 taking advantage of the previous decline 43 at the time of the tilt of the vehicle, so that an area of ​​the opening 41 can be effectively applied to improve the previous lightness, even when part of the opening 41 is covered with the cover 50 of the engine centre

As shown in Figures 1 and 8 to 11, a blade 44 having a top surface 44c in the form of a sloping surface 44c inclined further downward with the distance closest to the front is formed in the front part of the opening 41.

The adoption of this arrangement makes it possible for the blade 44 to increase the pressure on the ground of the previous wheel 1F, and also that the lightness at the time of the initial phase of the rotation of the vehicle body is also improved, from the point of view in which the opening 41 is located at the rear of the blade 44 so that the adhesion of a running current to the surface of each cover 30 of the side engine when it occurs behind the blade 44 is suppressed .

As shown in Figures 1 and 3, the blade 44 has a protrusion 54 in the transverse exterior extending upwardly from the blade 44.

The adoption of this arrangement makes it possible for the running current to be controlled so that it flows in the longitudinal direction of the vehicle by applying the shoulder 54 to suppress the phenomenon that the running current flowing in the blade 44 is diffused in the transverse direction. , thus enabling the straightening effect on the blade 44 to be enhanced.

The upper part of the cover 50 of the central motor can form the shoulder 54 (see Figures 12 and 13).

As shown in figures 1 and 2, the windshield 21 is arranged in the front part of the steering mechanism ST, and the opening 41 is exposed to the outside above the blade 44 in front view of the vehicle (figure 1).

The adoption of this arrangement makes it possible that the running current that has been straightened with the blade 44 is directed to the side of the motorist taking advantage of the pivot space S (see Figure 4) of the steering mechanism ST, thus enabling not only the effect of protection of the motorist against the wind that must be reinforced with the windshield 21 but also grants an adequate degree of running current to the motorist,

5 at the same time enabling the suppression of a negative pressure generated

on the back of the windshield 21.

A suitable mounting structure can be applied to mount the upper engine cover 40 and the central engine cover 50 to the body frame 10.

The top and center engine covers can be assembled as described below, for example.

In accordance with the present embodiment, an inner panel 60 is disposed inside the cover 50 of the central motor and a side panel 70 is disposed at the rear of the cover 50 of the central motor. Thus, a mounting structure of the cover 40 of the upper motor and the cover 50 of the central motor will be described together with a mounting structure of the inner panel 60 and the side panel 70.

As shown in Fig. 5, a headlight 23 is fixed to the tip 22 so that a headlight box is located in the tip with location pins 23p, 23p, after being fastened thereto with screws 23b, 23b. Each of the turn signals 24 is fixed to the tip 22 by attaching an intermittent mounting arm 24a to the tip 22 with a screw 24b. It is noted that, with reference to Figure 5, the upper half shows the state in which the upper engine cover 40 is mounted, and the lower half shows the state in which the upper engine cover 40 is disassembled.

As shown in Figures 8 and 9 as well as in Figure 5, the cover 40 of the upper motor has, at the bottom of the front part, the fixing parts 45 and 46, with their respective holes arranged for screw insertion .

The upper engine cover 40 is fixed to the tip holding the

fixing part 45, together with the headlight 23 with the screw 23b, while fixing the fixing part 46, together with the flashing mounting arm 24a to the tip 22 with the screw 24b.

As shown in figures 8 and 9 as! As in Figure 3, the cover 40 of the upper motor has at the inner side of the surface of the upper part of the upper internal rose-hole holes 47 and 48 and on the inner side at the center of the upper part a hole 49 of hitch. The cover 40 of the upper motor also has in the front and rear parts of the lower part of the opening 41 holes 40h1 and 40h2 of engagement of the inner panel 60 and of the side panel 70.

Meanwhile, as shown in Figure 3, the cover 20 of the front engine has on the side a mounting piece 20f that extends behind as an integral part, and this mounting piece 20f has holes 27, for screw insertion . The housing 23c of the headlamp 23 also has a mounting part 23f next to it that extends behind 23f as an integral part, and this mounting part 23f has a hole 28 for inserting a screw. With reference to FIG. 3, reference numeral 29 indicates a tip used for fixing the cover 20 of the front motor and specified in the form of a protrusion that extends forward from the header tube 11, and this tip 29 has in the outer side a 29p hitch projection.

The cover 40 of the upper engine is fixed to the headlight housing 23c carrying the hook hole 49 to the hitch with the tip 29p of the tip 29, followed by the insertion of the screw into the screw insertion hole of the case 23c of the headlamp from the inside ~ L \ to connect the screw to the hole 48 of the internal rosea. The cover 40 of the upper motor is also fixed to the side of the cover 20 of the previous motor by inserting the screws into the screw insertion holes 27, 27 of the previous motor from the inside to join the screws to the holes 47, 47 of internal rosea.

A hitch 61 of the inner panel 60, as described below, shall be reversibly attached to the hitch hole 40h1 being inserted therein. A hitch shoulder 58p of the cover 50 of the central motor, as described below, must be reversibly connected to the hitch hole 40h2 being inserted therein.

It is noted that, with reference to Figure 8, a H-Round hole is specified as an anchor hole for harness fixation.

Figure 6 is a side view of the inner panel 60. Figure 17 is a front view of the inner panel 60. Fig. 18 is a sectional view taken along line cc of Fig. 16. Fig. 9 is a pianta view of the inner panel of Fig. 18.

As shown in these figures, as in Figure 3, the inner panel 60 is fixed reversibly fixed to the side of the upper engine 40 by engagement of the aforementioned hitch 61 in the upper part of the inner panel with the hole 40h1 hitch cover 40 of the upper engine. The inner panel 60 has at the bottom a hook hole 62 adapted for engagement with a projection 15p at the upper end of a puntai 15s presented as an integral part in the form of a projection that extends from a suspension support 15b of the engine in the lower end of the tube 15 descending towards the anterior part of the part

ΊΛ lower engine suspension support. The engagement of the shoulder 15p with the hook hole 62 allows the inner panel 60 to be located in the frame 10 of the body and at the same time, be fixed reversibly thereto.

The inner panel 60 has in the upper part more than one hook hole 63h (two holes in the inner panel illustrated) and along the front edge more than one hook hole 65h (five holes in the inner panel illustrated). The bump projections 53p and 55p of the cover 50 of the central motor, as described below, are intended, respectively, for fixing in these holes 63h and 65h of engagement, thus allowing the cover 50 of the central motor to be reversibly joined to the outside of the inner panel 60 by inserting insert members in the form of a remâche (each of which is well known "per se" and the same will be applied hereafter) in the insertion holes of the bump projections 53p and 55p from the inside of the inner panel 60.

Figure 20 is a side view of the side panel 70. Figure 21 is a pianta view of the side panel of Figure 20.

As shown in these figures, as in Figure 3, the side panel 70 is fixed to the main frame 12 by fastening a fixing part 71 having a screw insertion hole to the main frame 12 with a screw 72.

The side panel 70 has in the upper part more than one hook hole 72h (two holes in the illustrated side panel) and in the lower part more than one hook hole 73h (two holes in the illustrated side panel). The

5 projections 56p and 57p of coupling of the cover 50 of the central motor, as described below, are intended to be fitted in these holes

In addition, the cover 50 of the central motor has on the rear of the upper part a hitch 59p equivalent to the hitch 58p.

Meanwhile, as shown in Figures 2 and 3, a side cover 90 used to cover the bottom of a fuel tank FT has a hook hole 91 capable of reversibly engaging with the hitch boss 59p. The hitch hole 91 has the same shape as the hitch hole 40h2 of the upper motor cover 40.
