SYSTEM. SAVING OF VEHICLE FUEL
MULTIPLE COMPONENTS
FIELD OF THE INVENTION
The present disclosure relates to ground vehicles and more particularly to the reduction of aerodynamic drag of such vehicles and more particularly to semi-trailers.
In another configuration, the present disclosure provides a fairing system for cinema trailers and particularly for semi-trailers that have a movable axle assembly - often referred to as a bogie or tandem. For purposes of the present disclosure, the term axle assembly is intended to be interchangeable with bogie, tandem, or other equivalent terms.
BACKGROUND OF THE INVENTION
Most tractors today get approximately 2.5-3 kilometers per liter (6-7 mpg) of fuel leaving significant potential to improve the fuel economy of tractors. Reducing the fuel consumption of tractors would directly impact the costs of transporting goods, serving businesses and consumers alike.

resistance that the vehicle incurs while traveling. As the drag forces increase, so does the fuel consumption. One area of a semi-trailer where the drag forces are high is the chassis of a semi-trailer. Another area of the semi-trailer where aerodynamic forces are high is the rear end of a semi-trailer container. When the tractor is moving, air flows under and around the semi-trailer, placing significant drag forces on the wheels, chassis, and rear of the truck. The tractor truck must use more power to overcome the drag, thereby increasing fuel consumption. Therefore, it is more desirable to reduce drag under the chassis and at the rear end of a semi-trailer.
What is needed then is a drag reduction system for a semi-trailer that improves fuel economy.
It would therefore be desirable to provide a drag reduction system for a semi-trailer that overcomes the aforementioned and other disadvantages.

Subframe 18 carries an axle assembly 30 and axle assembly 30 includes at least one axle 32, and a plurality of wheels 34, and a suspension (not shown). In many configurations, the axle assembly 30 includes brakes, hydraulics, air lines, and connections to air suspension systems as known in the art. It is understood that axle assembly 30 may include one, two, or more axles, wherein each axle may include two or more wheels. Therefore, as is well known in the art, the movement of the axle assembly 30 relative to the main frame 14 places the wheels at correspondingly different locations along the longitudinal axis 16. Therefore, for example, locating the wheels 34 closer to a front of the main frame 14 allows easier maneuverability in congested areas and tight-radius turns, such as at an intersection. In addition, the selective location of the axle assembly 30 provides what is needed for improved load distribution.

In selected configurations, the given distance is adjustable, generally within a fairing range of motion less than about 0.914 m (3 ft). In addition, the range of motion of the fairing extends from a proximal position by locating a portion of the fairing 102 to approximately 2.54 cm (1 inch) from the wheels 34 of the axle assembly 30 to approximately 0.914 m (3 feet) from the wheels 34.
Fairing 102 produces a smooth contour and reduces drag with respect to passing air flow, such as is induced when semi-trailer 12 is being towed by a tractor truck. Fairing 102 can extend along longitudinal axis 16 from adjacent the landing gear to adjacent to the wheels of the axle assembly - subject to the range of motion of the fairing as stated above. It is understood that fairing 102 can extend along longitudinal axis 16 for as little as ten percent (107) of the distance between wheels 34 and landing gear 36 to one hundred and ten percent (110%) of the distance thus encompassing landing gear 36. In one configuration, fairing 102 is

30. Conveniently, the fairing 102 extends as close to the pavement as operationally possible and is at least as wide as the width of the axle assembly 30. The fairing
102 it can extend across substantially the entire width of the semi-trailer or a percentage of the width. Therefore, the width of the fairing 102 can span the width of the wheels 34, or end within the spacing between the wheels 34. It is further contemplated that fairing 102 may have lateral extensions located outside the width of wheels 34, and therefore may locate at least a portion of wheels 34 between lateral extensions at selected positions of fairing 102 relative to the axle assembly 30.
Fairing 102 is movable relative to main frame 14 such that sub-frame 18 (and axle assembly 30) move along longitudinal axis 16 relative to main frame 14, where the given spacing is maintained between axle assembly 30 and fairing
102. That is, the position of the fairing 102 relative to the axle assembly 30 is independent of the position of the axle assembly 30 relative to the main frame 14.

By locating a trailing edge 104 of fairing 102 as close as possible to wheels 34 of axle assembly 30, it has been found that the efficiency of semi-trailer 12 increases (or conversely decreases the required fuel consumption). However, it is understood that different road conditions, loads, or environmental conditions may require adjusting the spacing between fairing 102 and wheels 34 within the range of motion of the fairing. That is, the aerodynamic efficiency of fairing 102 may depend on the specific spacing of fairing 102 and wheels 34 for a given set of operating conditions. Therefore, fairing 102 can be mounted at any of a variety of locations throughout the fairing range of motion relative to axle assembly 30 to maximize fairing effectiveness.
102. However, once the relative position of fairing 102 relative to axle assembly 30 has been temporarily fixed or selected, fairing 102 and axle assembly 30 are moved as a unit relative to the main frame 14 of the semi-trailer.

Fairing 102 may include a frame of '^' ájí'.gíia.do - ^ IW as shown in Figure 3 in which se..re.ti ^, na.xi, .. CQ.lQ ^ .a a coating 108 to give an aerodynamic shape. The aerodynamic shape of the fairing 102 can be any shape that reduces aerodynamic drag. The fairing frame
106 You can define any one of a variety of shapes from curvilinear surfaces, such as a dome to a point or a pyramid shape.
As shown in Figures 3 and 4, fairing 102 may include lighting 110 for safety, visibility, and marketing. Illumination 110 may be any known in

While fairing 102 is described in terms of fairing frame 106 and liner 108, it is understood that fairing frame 106 and liner 108 may be a substantially integral or mixed structure, such as by molding or forming, as shown in Figure 4. In this construction, fairing 102, or at least portions of fairing 102, can be formed by polymer molding.

Mounting or connecting fairing 102 relative to semi-trailer 12 can be accomplished through a variety of configurations.
In one configuration, the main frame 14 includes at least one and can be as much as a multitude of rails 112 extending along the longitudinal axis 16. The fairing frame 106 includes a corresponding number of sliders or supports 114 that are received slidably within rails 112 such that fairing 102 can be moved relative to the main frame
14. Fairing frame 106 is further connected to axle assembly 30 or subframe 18, such that axle assembly 30 moves relative to the main frame
14, the fairing 102 moves correspondingly within the rails 112 along the longitudinal axis 16. This maintains the relative spacing between the fairing 102 and the wheels 34 of the axle assembly 30 independent of the movement of the main frame 14 relative to the assembly. axis 30 and / or sub-frame 18.
In one configuration, it is contemplated that the sliders

In an additional configuration, as shown in
Figures 6A and 6B, the fairing 102 includes a mounting portion 90 and a frame retention portion 92, where a telescopic or sliding interface is formed between the mounting portion 90 and the frame retention portion 92.
Mounting portion 90 is configured to be attached to subframe 18 or axle assembly 30 and frame retention portion 92 is configured to support or define fairing 102. The range of motion between mounting portion 90 and the Frame retention portion 92 defines the range of fairing motion - from 2.54 cm (1 inch) to 0.914 m (3 feet). Mounting portion 90 and frame retention portion 92 can be detachably connected, but fixed in such a way that an operator can adjust and then tow semi-trailer 12 with fairing 102 in a selected position relative to wheels 34 (shaft assembly 30). In this configuration, since the fairing frame 106 mounts only to the

there is no need for rails 112 to the lower edge of the main frame 14.
It is contemplated that fairing 102 may have a substantially open rear end, a closed rear end, or a partially occluded rear end. That is, the fairing 102 can define the air flow diversion surface, where the rear of the fairing (facing the axle assembly) is open forming a gap.
Alternatively, fairing 102 can define a substantially enclosed volume that precludes entry or exit. In a further configuration, the fairing 102 may have a partially occluded rear end, such as by means of panels or sections that inhibit flow into the fairing gap from the rear. Depending on the specific configuration, the panels can be located in different positions along the longitudinal axis. Therefore, some panels at the rear of the fairing may be proximal to the axle assembly and other panels may be distal to the axle assembly.
As shown in Figure 7, fairing 102 can include an inlet opening 118 and at least one flow path that fluidly connects inlet opening 118 and an outlet opening 120. In a ·· -, · <Y) configuration, the path of f luj'b'gzjqiibiy; fluently the inlet opening 118 and the outlet opening 120 is formed of at least one ventilation duct
122. Outlet opening 120 may have a cross sectional area less than or equal to a cross sectional area of inlet opening 118.
In an additional configuration, as shown in
Figure 5, the disclosure provides a diffuser 300 to reduce air flow between the spaced shafts in the shaft assembly 30, such as a tandem. Diffuser 300 defines a generally curvilinear surface that at least partially spans a diameter of at least one of a starting and a final shaft in the shaft assembly, as shown in the images. In one configuration, diffuser 300 extends along the bottom portion of the shafts. In a further configuration, diffuser 300 substantially spans the start and end axis. The diffuser can be a one-piece construction or multi-piece construction, where the multiple parts are assembled around the axes.
Diffuser 300 may include channels 310 generally extending along longitudinal axis 16, where channels 310 direct the air flow down and just behind wheels 34, intersecting in this manner.
<img file="MX355152B_D0015.tif" />
with pavement splashes and substantially the ability of the -cuaJ-pi oadnr ^ g of the pavement to rise from the pavement surface.
In a further configuration, diffuser 300 may be a substantially flat member that extends along longitudinal axis 16 from just ahead of the start axis to just behind the end axis. This configuration accommodates the construction of the tandem by the original equipment manufacturer and the occupation of the space above the initial axis and the final axis with wiring, hoses and struts. In those tandem constructions, in which the space above the shafts is free, the diffuser 300 can extend above and below the shafts, thereby partially enclosing the shafts. In a further configuration, diffuser 300 (either as a single member or multiple components) extends across a majority of a width between the wheels of the initial axle.
Diffuser 300 therefore joins between the axles of the axle assembly and below the main frame to span the distance between the axles creating an aerodynamic surface. This surface controls the air flow under the semi-trailer 12 eliminating the need for a lower door mounted panel on the rear doors.
The diffuser 300 also channels the air by passing a
s.
lower bumper of semi-trailer 12 rewu ^ aádáLel of the drag stream and also channels a portion of the controlled air to knock down pavement fog during rain.
As shown in Figures 8 and 9, in those configurations of the semi-trailer having a container with a rear end 40 of the container including a pair of doors 42 that can be opened as is known in the art, each door 42 can include a vertical flap 400 hingedly connected to door 42 along an outer edge and a horizontal flap 402 hingedly connected along an upper portion of door 42. Vertical flap 400 is movable between an extended position that generally extends rearwardly from the rear end 40 of the container to a retracted position where flap 400 is generally parallel to door 42.
In one configuration, at least one lower hinge 404 and one upper hinge 406 connect vertical flap 400 to door 42, where hinges 404, 406 are mechanically connected such that actuation of lower hinge 404 will impart actuation of the upper hinge
406. A bar may form an interconnection between hinges 404, 406 to impart common actuation.

Plate 408 can be of any configuration as dictated by the selected material of plate 408 and fin 402. In this configuration , plate 408 is attached to door 402 to locate barrel 410 adjacent to an existing hinge connection between container door 42 and the container.
To install fin 402, a hinge pin is removed
402 of the corresponding hinge 404 or 406 on the door 42 and the barrel 410 of each of the plates 408 fixed to the flap
402 aligns with barrel 420 of existing hinge 404, 406. Then an extended hinge bolt 402 is located in the existing hinge 404, 406 and plate barrel 410
408 fixed to the flap 402. The flap 402 is therefore rotatably mounted on the container.
Referring to the drawings, a link 414 that is separated from the hinges 404, 406 links the flap 402 to the door 42. The link 414 includes a generally U-shaped base 416 having a closed end of the U rotatably connected to door 42, such as by means of a coupler or channel support. Each leg of the U-shaped base 416 is pivotally connected to an arm 418 which

INDUSTRIAL
The closed end of the U-shaped base 416 forms the bar that interconnects hinge 404, 406 (or binds) to impart common actuation.
With respect to the horizontal top flaps 402, these flaps 402 may be hingedly connected to the container door by attaching a hinge plate 422 to the flap 402 and door 42 and secured by means of a bolt
421 such that flap 402 is rotatable between a closed position generally parallel to door 42 and an open position that extends away from door 42.
While the two fins 402 can be selectively rotated between the open and closed positions by any of a number of mechanisms, a satisfactory mechanism includes a first link 424 having a first end pivotally connected to the horizontal fin 402 at a distance from the axis of rotation of the horizontal fin 402. A second end of the first link
424 it is pivotally connected to a slider 426, where the slider 426 is connected to the door 42 to slide vertically along a vertical direction. In one configuration, slider 426 can be vertically pulled downward with a push actuated pivot bar, causing horizontal flap 402 to rotate downward toward<sup>-</sup>'lM'-n'püé.rt'áó 4 2' container. Conversely, to place the horizontal fin
402 In the open position, slider 426 is pushed upward by means of thrust causing flap 402 to rotate to the open position.
Therefore, the system provides an aerodynamic system for the rear of the container that has four movable flaps - two vertical side flaps 400 and two horizontal top flaps 402 - and a shaft diffuser 300, as set forth below.
Generally, the rear wings 400, 402 are attached to the top and side of the rear end of the semi-trailer, including a side wing 400 and top wing 402 for each door 42. The side wings 400 include an aerodynamic panel 430 and a mounting that use the door hinges to swing the doors and the door frame to roll up doors. The streamlined panel material can be plastic, metal, or other semi-rigid to rigid material, including fabric in a frame. For mounting the aerodynamic panels 430 to the door 42 and a deployment device, the respective flap 400, 402 is mounted on the truck by the method described above and is deployed by moving the panel 430 to the open position by using a pivot bar.

In a further configuration, the present disclosure provides what is necessary to streamline the main frame 14 of the semi-trailer. In this configuration, main frame 14 includes two and sometimes three (or more) elongated beams that extend along longitudinal axis 16, where a multitude of crossbeams extend transverse to elongate beams to provide a rigid frame on which a board is attached to form the floor or deck of the semi-trailer.
In this configuration, overlay 502 is secured through the bottom (or exposed edge) of cross beams to form a substantially continuous underside of the semi-trailer as shown in Figure 3. Overlay 502 is contemplated to extend to through substantially the entire area of the underside of the semi-trailer - including between the wheels and the bottom of the main frame. Coating 502 can be any of a variety of materials such as sheet metal, composites, plastics such as polycarbonate, or even tightly woven fabrics.
The semi-trailer includes a coating 502 that runs either longitudinally or horizontally along the

Overlay 502 can be attached by any of several methods including rails, snaps, screws, bolts, sheet metal, etc. It is contemplated that the I-beam deck can extend all or a portion of the bottom - from the front to the back and from side to side.
Referring to Figures 10, 11, and 17, in another configuration, a fairing 101 includes a pair of opposite side surfaces 109 and an initial surface 111. The pair of opposite side surfaces 109 are separated by a distance that is substantially equal to width of the semi-trailer. The distance can vary in width depending on the size, design of the semi-trailer and to maximize the aerodynamic advantage of the system. By substantially equal to the width of the semi-trailer, it is meant that the opposing side surfaces 109 are spaced inward from the side edge of the semi-trailer 12 by approximately 0 to 60.96 cm (0 to 24 inches) and more

Alternatively, all or a portion of the side surfaces 109 may protrude from about 0 to 10.16 cm (0 to 4 inches) from the side edge of the outer perimeter of the semi-trailer. Initial surface 111 substantially spans the distance between opposite side surfaces 109 and defines a bow 113 to reduce a drag coefficient of fairing 101. As shown in Figure 15 and described below, in one configuration, bow 113 is formed from two panels
103, 105 integrally connected. Each of the panels
103, 105 may include a top flange 187 extending forward from bow 113 and a side wall
