A mudflap for a vehicle, configured to be installed on the vehicle, comprising a base layer, configured to be attached to the vehicle; and an exposed layer, configured to be attached to the base layer and movable between an operation position, in which the exposed layer is attached to the base layer, and a cleaning position, in which the exposed layer is detached from the base layer; the base layer comprising a plurality of protrusions and the exposed layer comprising a plurality of orifices, the protrusions of the base layer being engaged in the orifices of the exposed layer when the exposed layer is in its operation position.

Drag reducing systems for tractor-trailer combination vehicles are provided. In one aspect, a drag reducing assembly generally includes a stowable mud flap rotatably coupled to a mounting bracket and a linkage. The linkage is configured to transition the mud flap between a first, deployed position, to a second, stowed position. The mud flap is generally positioned adjacent a wheel and tire of the vehicle, downstream of airflow. In the first position, the mud flap may be deployed at an angle of about 90 to the ground. In the second position, the mud flap may be stowed at an angle of about 90 from the first position.

A mud flap assembly includes a flexible elongated spine to which protective scales are permanently or removable attached in a spaced apart array with an overlapping configuration. An attachment, such as an adhesive, magnets, or weatherstrip is fixed to the spine. The attachment secures the spine to a flange or edge of a fender of a vehicle.

A vehicle with deployable pliable fairing skirts and a controller for controlling deployment of the skirts are provided. The pliable fairing skirts are deployable over openings of wheel wells for the vehicle to provide additional streamlining for the vehicle. The pliable fairing skirts are stowable when the brakes of the vehicle may benefit from additional cooling airflow. The skirts are also stowable when environmental conditions may result in damage to the skirts or when steerable wheels of the vehicle would protrude from the opening.

A vehicle function arrangement for a vehicle includes a fender frame and a utility unit. The fender frame is adapted for attaching to a vehicle wheel position of the vehicle, wherein the fender frame has a sideward extension surface arranged for outwardly extending from the vehicle wheel frame. The utility unit is provided at the sideward extension surface of the fender frame for creating an additional utility space for the vehicle. In one embodiment, the vehicle function arrangement is installed to the vehicle wheel frame by fastening the fender frame of the vehicle function arrangement to the vehicle wheel frame.

A mud flap assembly includes a flexible elongated spine to which protective scales are permanently or removable attached in a spaced apart array with an overlapping configuration. An attachment, such as an adhesive, magnets, or weatherstrip is fixed to the spine. The attachment secures the spine to a flange or edge of a fender of a vehicle.

An apparatus for providing a vehicular fender extension comprise a wheel-well casing having a top surface, a bottom surface, an inside edge and an outside edge, the wheel-well casing being adapted to fit within a vehicular wheel-well, a guiderail located at the outside edge of the wheel-well casing, and an extending member slideably supported by the guiderail, the extending member having a top surface, a bottom surface, an inside edge and an outside edge, extending between first and second ends. The apparatus further comprises at least one actuator operable to move the extending member between a first position wherein the extending member is contained within the wheel-well casing, and a second position wherein the outside edge of the extending member is distal from the outside edge of the wheel-well casing.

A spray protection device (1) for a wheeled vehicle (20) having at least one wheel (21) standing on the ground, said device (1) comprising a spray shield (2), suitable for being arranged at least in part behind the wheel (21), and connection means (3) for connecting the shield (1) to said vehicle (20), the spray shield (2) presenting a face suitable for facing towards the wheel (21) to be protected and an opposite face, referred to as the back of the shield (2), the connection means (3) for connecting the shield (2) to the vehicle (20) being configured, when the shield (2) is coupled to the vehicle (20), to enable the shield (2) to move between a high position, at a distance from the ground, and a low position, close to the ground.

The device (1) comprises resilient shield (2) return means in the high position and a surface carried by the shield (2) and suitable for being exposed to the airflow generated when the wheeled vehicle (20) is moving forwards, said surface being configured, under the action of said airflow, to enable the shield (2) to move in a direction that is opposite to the direction of the return force.

An optically and aerodynamically improved body for a motor vehicle has a wheel well cover with at least one wheel well for receiving a wheel. The wheel well cover is designed in such a way as to be adjustable by an adjusting mechanism in accordance with the wheel angle, and includes at least two ring portions which surround part of the wheel and which are arranged in such a way as to be movable at least partially into each other and at least partially relative to one another.

An apparatus for providing a vehicular fender extension comprise a wheel-well casing having a top surface, a bottom surface, an inside edge and an outside edge, the wheel-well casing being adapted to fit within a vehicular wheel-well, a guiderail located at the outside edge of the wheel-well casing, and an extending member slideably supported by the guiderail, the extending member having a top surface, a bottom surface, an inside edge and an outside edge, extending between first and second ends. The apparatus further comprises at least one actuator operable to move the extending member between a first position wherein the extending member is contained within the wheel-well casing, and a second position wherein the outside edge of the extending member is distal from the outside edge of the wheel-well casing.
