Abstract

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.

First claim

What is claimed is:

1. A wheel of a vehicle, comprising:
a rim;
a hub portion;
at least two spokes which connect the hub portion to the rim;
a covering element by which at least one spoke gap between the spokes is covered at least partially by the covering element, wherein
the covering element is a single-piece having a wing portion that deforms axially away from a remainder of the covering element and the wheel when heat is supplied, wherein a cut in the covering element separates the wing portion and the remainder of the covering element,
the covering element is connected directly to the wheel, and
the single-piece covering element is configured from a single composite material.

2. The wheel according to claim 1 , wherein
the covering element is configured from a fiber composite plastic with a matrix material and fibers which are embedded in the matrix material, and
the covering element is formed from a laminate having a plurality of individual layers which are layered on one another.

3. The wheel according to claim 2 , wherein
the covering element has at least one uppermost individual layer, in the case of which the fibers are arranged such that an upper symmetrical laminate structure is configured as viewed with regard to a center plane of the individual layer.

4. The wheel according to claim 3 , wherein
the upper laminate structure is formed by way of a plurality of unidirectional individual layers which are layered on one another, and has a symmetrical layer structure as viewed with regard to a center plane of the upper laminate structure.

5. The wheel according to claim 3 , wherein
the upper laminate structure is formed by way of at least one multidirectional individual layer, and has a symmetrical layer structure as viewed with regard to a center plane of the upper laminate structure.

6. The wheel according to claim 3 , wherein
the wing portion has an asymmetrical layer structure as viewed with regard to a center plane of the wing portion, and
the layer structure of the wing portion is formed by way of the upper laminate structure and at least one additional lower individual layer, the fibers of which are oriented at least approximately in the radial direction of the wheel as viewed in the installed state of the covering element.

7. The wheel according to claim 1 , wherein
the covering element in each case comprises, at least on edge regions which adjoin the spokes, a limb which projects at least approximately in an axial direction of the wheel from the covering element and is of flexible configuration.

8. The wheel according to claim 7 , wherein
the limb has an undercut on an edge, which undercut when installed is hooked into a spoke edge which faces the vehicle.

9. The wheel according to claim 8 , wherein
the undercut comprises a latching lug for latching into a spoke edge.

10. The wheel according to claim 9 , wherein
the undercut and/or the latching lug is coated with a plastic material.

11. A wheel of a vehicle, comprising:
a rim;
a hub portion;
at least two spokes which connect the hub portion to the rim;
a covering element by which at least one spoke gap between the spokes is covered at least partially by the covering element, wherein
the covering element is a single-piece having a wing portion that deforms axially away from the wheel when heat is supplied,
the covering element is connected directly to the wheel,
the single-piece covering element is configured from a single composite material,
the covering element is configured from a fiber composite plastic with a matrix material and fibers which are embedded in the matrix material,
the covering element is formed from a laminate having a plurality of individual layers which are layered on one another,
the covering element has at least one uppermost individual layer, in the case of which the fibers are arranged such that an upper symmetrical laminate structure is configured as viewed with regard to a center plane of the individual layer, and
the upper laminate structure is formed by way of at least one multidirectional individual layer, and has a symmetrical layer structure as viewed with regard to a center plane of the upper laminate structure.

12. A wheel of a vehicle, comprising:
a rim;
a hub portion;
at least two spokes which connect the hub portion to the rim;
a covering element by which at least one spoke gap between the spokes is covered at least partially by the covering element, wherein
the covering element is a single-piece having a wing portion that deforms axially away from the wheel when heat is supplied,
the covering element is connected directly to the wheel,
the single-piece covering element is configured from a single composite material,
the covering element is configured from a fiber composite plastic with a matrix material and fibers which are embedded in the matrix material,
the covering element is formed from a laminate having a plurality of individual layers which are layered on one another,
the covering element has at least one uppermost individual layer, in the case of which the fibers are arranged such that an upper symmetrical laminate structure is configured as viewed with regard to a center plane of the individual layer,
the wing portion has an asymmetrical layer structure as viewed with regard to a center plane of the wing portion, and
the layer structure of the wing portion is formed by way of the upper laminate structure and at least one additional lower individual layer, the fibers of which are oriented at least approximately in the radial direction of the wheel as viewed in the installed state of the covering element.
