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.

A fender assembly for an agricultural tractor including a carrier bracket which supports a wheel fender adjacent to a vehicle wheel. A steering mechanism is provided as part of the fender assembly, such that the wheel fender can be rotated relative to the carrier bracket. Accordingly, the rotation of the wheel fender can be controlled based on a steering signal generated by the vehicle steering system, to ensure that the wheel fender accurately follows the movement of the adjacent tractor wheel.

A car having: two front wheels; two rear wheels; a body, which has two front wheel compartments, each housing, on the inside, a corresponding front wheel, and two rear wheel compartments, each housing, on the inside, a corresponding rear wheel; and two covering panels, each arranged in the area of a corresponding wheel compartment to close the wheel compartment. Each covering panel is mounted on the body so as to be movable between a contracted position, in which the covering panel is completely flush with the body, and an expanded position, in which the covering panel is at least partially spaced apart from the body. Two actuator devices are provided, each coupled to a corresponding covering panel so as to move the covering panel between the contracted position and the expanded position.

A mudguard fastening support is intended to connect the mudguard to a hub of a turning wheel. In a normal turning position, the mudguard turns with the wheel. The mudguard fastening support has a flexible structure in such a manner that a stop element prevents the mudguard from turning along with the wheel at an angle that is larger than a specific turning angle. With the flexible structure the mudguard is returned to turn with the wheel at an angle that is smaller than said specific turning angle. The mudguard fastening support has a turning sleeve to be fixed to the mudguard and a support element to be fixed to the hub of the wheel. The turning sleeve and support element have form surfaces facing each other, one of which forms a support surface and the other forms a mating surface. The support surface has a tip part with a rounded peak toward the mating surface. The mating surface has an operating position recess which is furthest away from the support surface and to which in a normal operating situation the tip part is to be arranged, and adjacent to the operating position recess, a bevelled surface.

Generally described, an articulated wheel fairing system for a vehicle having a steering system with a neutral steering input and a non-neutral steering input is provided. The articulated wheel fairing system provides clearance to the steer tire and wheel of the vehicle during non-neutral steering input, such as when the vehicle is turning at slower road speeds. The wheel fairing system generally includes an articulating fairing panel configured to cover at least a portion of the steer wheel, where the fairing panel movable from a first position adjacent to the steer wheel, such as when the vehicle is traveling at higher road speeds, to a second position outwardly from the first position. The wheel fairing system includes a mechanical linkage or actuator coupled to the fairing panel and the vehicle and configured to move the frame between the first position and the second position relative to the vehicle.

A number of variations may include a method comprising fixing a wheel cover on a wheel so that the wheel cover remains static as the wheel rotates on a horizontal axis and turns with the wheel as the wheel turns on a vertical axis comprising attaching a bearing system to a knuckle of a wheel; and attaching the wheel cover to the bearing system and the knuckle.

A drag reducing device for a motor vehicle having a vehicle body and at least one substantially semi-circular wheel-well for receiving a wheel capable of vertical and rotational movements with regards to the vehicle body, the vehicle comprising unsprung masses associated with the at least one wheel; wherein the drag reducing device comprises a wheel-well cover configured to cover at least a portion of the wheel and of the wheel-well, a pivotal linkage pivotally connecting the wheel-well cover to the vehicle body, and a sliding linkage slidingly connecting the wheel-well cover to an element of the unsprung masses with one degree of freedom oriented in the vertical movement of the at least one wheel.

A wheel well guard for a wheel well of a vehicle has a plurality of trim elements, the trim elements being adjustable between a guarding position and a stowed position. An adjusting device is included, the adjusting device being coupled to the trim elements so as to move therewith in order to adjust the trim elements between the guarding position and the stowed position, wherein the trim elements are in the form of concentric lamellae which are disposed around a main axis and which can be adjusted synchronously between the guarding position and the stowed position by the adjusting device in the manner of a central shutter mechanism.

The wheel fairing system includes a mechanical linkage or actuator coupled to the fairing panel and the vehicle and configured to move the frame between the first position and the second position relative to the vehicle.

A wheel cover apparatus for a vehicle includes an upper planar section for at least partially covering the wheel outer side of a steerable wheel, a lower planar section for at least partially covering the wheel outer side of the steerable wheel, an adjustment device for adjusting a position and/or orientation of the upper planar section and a positioning device for positioning the lower planar section. The upper planar section can be arranged on a body of a vehicle so as to be pivotable about a first pivot axis extending in the longitudinal direction of the vehicle. The upper planar section and the lower planar section are connected to each other so as to be pivotable about a second pivot axis extending in the longitudinal direction of the vehicle. The upper planar section is coupled to the adjustment device in such a manner that, in a functional installed state in the vehicle, the upper planar section is movable relative to the wheelhouse by means of the adjustment device. The positioning device is a traction means transmission.
