A strut assembly for mounting an aerodynamic fairing assembly for attachment to a trailer of a tractor-trailer having a centerline, transverse structural support members extending between sides of the trailer, and longitudinal members extending along a length of the trailer. The strut assembly may comprise a mounting plate, a strut body, and a substantially rectangular composite spring. The mounting bracket comprising a mounting plate and a pair of spaced apart sidewalls. The strut body rotatably may be coupled to the pair of spaced apart sidewalls on the mounting bracket. The substantially rectangular composite spring may be coupled to an upper surface of the strut body and configured to contact an underside of the mounting plate of the mounting bracket to resist inward deflection from an external force applied to the strut body.

The aerodynamic skirt assembly for attachment to a trailer may comprise a side skirt fairing, a rear skirt fairing, and a secondary treatment. The side skirt fairing may comprise an inner surface and an outer surface. The rear skirt fairing may comprise an inner surface and an outer surface and located aft of the side skirt fairing. The secondary treatment may be coupled to the outer surface of the rear skirt fairing, wherein the secondary treatment is canted outwardly at an angle from the outer surface of the skirt fairing and configured to redirect the air around the at least one rear wheel assembly.

An air conduction device for a motor vehicle including an air conduction element and a movement device with adjustment kinematics. The air conduction element is movable relative to the remaining body as at least part of a tail side part of the vehicle body. The air conduction element moves between an inoperative position and at least one final operating position. The tail side part has a flow guiding area along which air flows which is designed to face an area surrounding the motor vehicle. The air conduction element has a surface which is at least part of the flow guiding area. The air conduction element is configured in its final operating position to lengthen the flow guiding area in the direction of a longitudinal body axis (X) of the body. The adjustment kinematics are configured in the form of multipoint joint kinematics.

A spoiler assembly (2) for a car (4) is disclosed. The spoiler assembly (2) comprises a support structure (10) and body portion (30) moveably mounted to the support structure (10). The support structure (10) is configured to be attached to the car (4). The spoiler assembly (2) comprises one or more actuators (14, 14, 16, 16′) for changing the orientation of the body portion (30), wherein the body portion (30) is arranged to be rotated with respect to the direction of travel (X) of the car (4).

A fairing assembly for at least one axle of a commercial vehicle is disclosed. The fairing assembly includes at least one forward fairing configured to be arranged at least partially in front of a drive wheel of the axle with respect to the longitudinal direction of the vehicle and at least one rear fairing configured to be arranged at least partially aft of the drive wheel. Each of the fairings includes at least one first portion made of a first material and at least one second portion adjoining the respective first portion where the second portion is made of a second material different from the first material.

Embodiments provide a gap reducer and a method of mounting the gap reducer to a vehicle. Such method includes attaching operably a bi-modulus bending member to a first vehicle in a cantilevered configuration along a vertical side of the first vehicle, where a cantilevered end of the bi-modulus bending member is arranged to extend within a gap arranged between the first vehicle and a second vehicle when the first and second vehicles are coupled. The bi-modulus bending member comprises an elongate bending element configured to elastically buckle and bend to a buckled configuration when a force component exceeds a threshold buckling force, and to elastically return to an unbuckled configuration when the force component is reduced below the threshold buckling force. A gap reducer panel is operably coupled to the bi-modulus bending member, the gap reducer panel having a length extending primarily in a vertical direction.

The present invention is related to an aerodynamic side skirt assembly for attaching a panel to a trailer or semi-trailer. The present invention comprise a coupler configured to be attached to a frame rail of the trailer and to a panel, a compressible element preferably with a curved shape used as a damper and a bracket with a preferably flat surface connected to the panel and a rib through the length of the bracket.

An active rear airfoil arrangement (10) for a trailing area of a vehicle having a turbulence creating area. The arrangement (10) is for connection with a static rear horizontal spoiler (20) associated with the rear portion of a vehicle and includes an active rear horizontal spoiler (30a, 30b, 30c). The active rear horizontal spoiler (30a, 30b, 30c) moves to a deployed position and forms a flow passage (48a, 48b, 48c, 48d) that extends horizontally across the top of a liftgate (12). In another aspect of the invention the active rear airfoil arrangement (10) includes vertical left and right active spoilers (32a, 32b; 36a, 36b) that move to create a flow passage (74,76, 88, 90) on the left side and right side of a liftgate (12).

An active front wheel deflector assembly (10) including a deflector panel (20) moveable between a stowed position and at least one deployed position wherein the deployment of the deflector panel (20) moves the deflector panel (20) into an airflow to direct air and improves aerodynamics. The active front wheel deflector assembly (10) combines linear actuation with rotational motion.
