A wheel of a vehicle has a rim, a hub portion and at least two spokes connecting the hub portion to the rim. At least one spoke intermediate space between the spokes is at least partially covered by a single-piece cover element. A wing portion of the cover element is deformed axially away from the wheel when heat is supplied. The cover element is connected directly to the wheel, and the single-piece cover element is formed from a single material.

A cover for a rim of a wheel of a vehicle. The cover, with fastening of the cover on the rim, can be arranged in at least partially overlap with a through opening of the rim delimited in the circumferential direction of the rim by respective spokes of the rim, whereby the through opening can be at least partially covered by the cover. The cover is directionally formed and has at least two slats, which delimit at least one channel arranged between the slats, through which air can flow in the installed position of the cover diagonally to a plane extending perpendicularly to the axial direction of the rim. The slats at least partially mutually overlap with respect to the installed position of the cover in the circumferential direction of the rim and along the axial direction of the rim.

The present invention relates to a plurality of airfoil rim wings, and/or fan-like blades which may be flat or take the form of airfoil wings in a preferred embodiment are attached to an automobile's wheel rims for the extraction of air pressure buildup within the wheel wells during forward movement to improve overall performance, styling and brake cooling. The airfoil rim wings, and/or fan-like blades may either be adhered to a wheel surface or individually or collectively fastened to wheels' hub using open-ended lug nuts, and securing lug bolts. Further, the airfoil rim wings, and/or fan-like blades may be arranged to specific concavity and angel of attack using twistable beveled washers on both sides of the airfoil rim wings, and/or fan-like blades.

A fiber-composite ventilation flap for a vehicle is made of a laminate formed by at least two individual tiers. At least one of the individual tiers has respective unidirectionally oriented fibers, and wherein the at least two individual tiers are arranged in the laminate in such a way that the fibers thereof are oriented at least predominantly differently to one another. The fibers of the at least two individual tiers are oriented differently to one another in such a way that at least one region of the fiber-composite ventilation flap curves about a predefined primary axis under the influence of heat and is thereby in an open state.

A vehicle wheel has spokes, on which cover elements are provided for a space between the spokes. The cover elements deform according to the temperature in such a way that, at higher temperatures, a passage of air through a region of the space between the spokes is possible, which is covered by the cover element at lower temperatures. In this way, the cover elements do not entirely cover the respective spaces between the spokes, and a rigid cap element is provided per intermediate space in addition to a cover element deforming according to the temperature. Alternatively, two cover elements are provided in each space between the spokes, next to one another in the circumferential direction of the wheel, wherein in the deformed state, one of the cover elements is curved outwards and the other cover element is curved inwards towards the vehicle.

The cover, with fastening of the cover on the rim, can be arranged in at least partially overlap with a through opening of the rim delimited in the circumferential direction of the rim by respective spokes of the rim, whereby the through opening can be at least partially covered by the cover. The cover is directionally formed and has at least two slats, which delimit at least one channel arranged between the slats, through which air can flow in the installed position of the cover diagonally to a plane extending perpendicularly to the axial direction of the rim. The slats at least partially mutually overlap with respect to the installed position of the cover in the circumferential direction of the rim and along the axial direction of the rim.

A variable aerodynamic wheel includes: a spoke wheel having a plurality of spokes connecting a hub and a rim together are spaced apart from each other, and a plurality of through spaces defined between the plurality of spokes to allow air to pass therethrough; a variable flap rotatably disposed in the plurality of through spaces of the spoke wheel, and configured in a shape to cover an associated through space so as to open or close the associated through space according to a rotation angle thereof; and a drive unit disposed in the spoke wheel, and connected to the variable flap such that the rotation angle of the variable flap is adjusted as rotational power is transmitted.

The invention relates to a vehicle wheel comprising a wheel rim (12) that has a hub portion (38), a rim base (36) for receiving a tire, a plurality of support portions (40) interposed between the hub portion (38) and the rim base (36), at least one interspace (42) between the support portions (40), and at least one cover element (44) associated with the interspace (42), characterized in that the cover element (44) can be transferred from a first position to a second position by pneumatic actuation.

Methods and systems of an active aerodynamic wheel cap device are provided. The active aerodynamic wheel cap device can be mounted to a vehicle wheel and configured to actuate from a flap-open to a flap-closed state. The flap-open state provides an air vent path from an outer portion of a wheel to an internal component of the wheel, especially at low speeds or during braking. The flap-closed state provides a substantially gapless aerodynamic cap for the wheel of the vehicle at highway speeds or during acceleration. The actuation of the active aerodynamic wheel cap device may be based on an all-mechanical controlled centripetal force movement mechanism.

Disclosed is a wheel cover for a vehicle. The wheel cover is supported to be relatively rotatable with rotation of a wheel having a tire attached to an outer periphery of the wheel. The wheel cover has a shape indicating a moving direction of a vehicle or a figure indicating the moving direction of the vehicle outward in a vehicle width direction, and is configured to be turned by an actuator such that, when the moving direction of the vehicle is changed, the shape or the figure indicates the moving direction of the vehicle.
