Abstract

The present invention relates to a wheel cover and to a wheel hub arrangement, wherein the wheel cover has a shielding section, which shields a gap formed between a hub and the wheel cover, and wherein a wheel hub arrangement is provided, in which a seal element is arranged in a gap formed between a wheel cover and the hub, which seal element is embodied as a profile seal.

First claim

The invention claimed is:

1. A wheel hub arrangement, comprising:
a hub; and
a wheel cover;
wherein the wheel cover is configured to be fixed in a recess in the hub such that the wheel cover delimits a region external to the hub directly axially outboard of the hub with respect to an inner region of the hub;
wherein a gap is located between the hub and the wheel cover;
wherein a seal element is arranged in the gap, the seal element having a main body and a sealing lip;
wherein the sealing lip projects radially outward from the main body and extends toward the region external to the hub directly axially outboard of the hub; and
wherein the main body of the sealing element is held by positive engagement in a receiving section of the wheel cover.

2. The wheel hub arrangement as claimed in claim 1 , wherein the main body and the sealing lip form a curved outer surface, which is curved concavely toward the outer region.

3. The wheel hub arrangement as claimed in claim 2 , wherein the sealing lip is configured such that, when there is a higher pressure in the region external to the hub than in the inner region, the contact pressure of the sealing lip on at least one of the hub or the wheel cover is increased.

4. The wheel hub arrangement as claimed in claim 3 , wherein the seal element is arranged in the preloaded state between the hub and the wheel cover, and wherein the hub has a stop surface, which secures the seal element against displacement toward the inner region.

5. The wheel hub arrangement as claimed in claim 4 , wherein the wheel cover has an engagement section, which is configured to be fixed in the recess in the hub.

6. The wheel hub arrangement as claimed in claim 5 , wherein the wheel cover has a shielding section, which shields the gap between the hub and the wheel cover in at least one shielding direction.

7. The wheel hub arrangement as claimed in claim 6 , wherein the shielding section is configured as an encircling projection and projects from the wheel cover substantially transversely to an axis of rotation.

8. The wheel hub arrangement as claimed in claim 7 , wherein the shielding direction is at a shielding angle of 0° to 90° to the axis of rotation.

9. The wheel hub arrangement as claimed in claim 8 , wherein a maximum shielding angle of the shielding direction is in a range from 20° to 90°.

10. The wheel hub arrangement of claim 9 , wherein the maximum shielding angle is in a range of 30° to 80°.

11. The wheel hub arrangement of claim 10 , wherein the maximum shielding angle is in a range of 35° to 70°.

12. The wheel hub arrangement as claimed in claim 9 , wherein the curved outer surface has a mean radius of curvature which is 0.3 to 2.5 times a width of the gap, wherein the width of the gap is the distance between a diameter of the recess and an exterior diameter of the wheel cover proximate the seal element.

13. The wheel hub arrangement of claim 12 , wherein the mean radius of curvature is 0.5 to 1.5 times the width of the gap.

14. The wheel hub arrangement of claim 13 , wherein the mean radius of curvature is 0.5 to 0.8 times the width of the gap.

15. The wheel hub arrangement as claimed in claim 1 , wherein the sealing lip is configured such that, when there is a higher pressure in the region external to the hub than in the inner region, the contact pressure of the sealing lip on at least one of the hub or the wheel cover is increased.

16. The wheel hub arrangement as claimed in claim 1 , wherein the seal element is arranged in the preloaded state between the hub and the wheel cover, and wherein the hub has a stop surface, which secures the seal element against displacement toward the inner region.

17. The wheel hub arrangement as claimed in claim 1 , wherein the wheel cover has an engagement section, which is configured to be fixed in the recess in the hub.

18. The wheel hub arrangement as claimed in claim 1 , wherein the wheel cover has a shielding section, which shields the gap between the hub and the wheel cover in at least one shielding direction.

19. The wheel hub arrangement as claimed in claim 18 , wherein the shielding section is configured as an encircling projection and projects from the wheel cover substantially transversely to an axis of rotation.

20. The wheel hub arrangement as claimed in claim 18 , wherein the shielding direction is at a shielding angle of 0° to 90° to the axis of rotation.

21. The wheel hub arrangement as claimed in claim 18 , wherein a maximum shielding angle of the shielding direction is in a range from 20° to 90°.

22. The wheel hub arrangement as claimed in claim 1 , wherein the main body and the sealing lip form a curved outer surface which is curved concavely toward the region external to the hub, and wherein the curved outer surface has a mean radius of curvature which is 0.3 to 2.5 times a width of the gap, wherein the width of the gap is the distance between a diameter of the recess and an exterior diameter of the wheel cover proximate the seal element.
