Abstract

A wheel includes an outer wheel ring, a hub at least one support device supporting the outer wheel ring on the hub, and an adjustment device configured to adjust the hub relative to the outer wheel ring, wherein the support device has multiple support elements which extend between the hub and the wheel ring, and wherein the support elements are arranged three-dimensionally such that the hub can be adjusted in five degrees of freedom relative to the outer wheel ring.

First claim

The invention claimed is:

1. A wheel, comprising: an outer wheel ring; a hub; at least one support device supporting the outer wheel ring on the hub; and an adjustment device configured to adjust the hub relative to the outer wheel ring; wherein the support device has multiple support elements which extend between the hub and the wheel ring; and wherein the support elements are arranged three-dimensionally such that the hub can be adjusted in five degrees of freedom relative to the outer wheel ring.

2. The wheel as claimed in claim 1 , wherein the adjustment device is configured to deflect the hub in different directions out of a geometrical center of the wheel.

3. The wheel as defined in claim 2 , wherein the adjustment device is configured to continuously deflect the hub.

4. The wheel as claimed in claim 2 , wherein the adjustment device is configured to move the hub along an orbital path about a geometrical center of the outer wheel ring.

5. The wheel as claimed in claim 4 , wherein the adjustment device is configured to vary the length of the support elements between the hub and the wheel ring.

6. The wheel as claimed in claim 5 , wherein the adjustment device comprises a telescopic device.

7. The wheel as claimed in claim 6 , wherein the adjustment device is at least one of electromechanically, hydraulically, and pneumatically operated.

8. The wheel as claimed in claim 7 , wherein the adjustment device is configured to adjust at least one of an elasticity and a preload of the support elements independently of one another.

9. The wheel as claimed in claim 8 , wherein the adjustment device is configured to adjust the position of the hub while maintaining the shape of the wheel ring, and wherein the wheel ring is in the form of a dimensionally stable or rigid ring.

10. The wheel as claimed in claim 8 , wherein the adjustment device is configured to deform the outer wheel ring during the rotation of the wheel.

11. The wheel as claimed in claim 10 , wherein the adjustment device is configured to continuously deform the outer wheel ring.

12. The wheel as claimed in claim 10 , wherein a control device is configured such that the adjustment device may be actuated to drive a wheel in rotation.

13. The wheel as claimed in claim 12 , wherein the adjustment device is configured to exert at least one of a drive torque and a recuperation action on the outer wheel ring.

14. The wheel as claimed in claim 1 , wherein the adjustment device is configured to move the hub along an orbital path about a geometrical center of the outer wheel ring.

15. The wheel as claimed in claim 1 , wherein the adjustment device is configured to vary the length of the support elements between the hub and the wheel ring.

16. The wheel as claimed in claim 1 , wherein the adjustment device comprises a telescopic device.

17. The wheel as claimed in claim 1 , wherein the adjustment device is at least one of electromechanically, hydraulically, and pneumatically operated.

18. The wheel as claimed in claim 1 , wherein the support device has multiple deformable support elements which extend between the hub and the wheel ring, and wherein the adjustment device is configured to adjust at least one of an elasticity and a preload of the support elements independently of one another.

19. The wheel as claimed in claim 1 , wherein the adjustment device is configured to adjust the position of the hub while maintaining the shape of the wheel ring, and wherein the wheel ring is in the form of a dimensionally stable or rigid ring.

20. The wheel as claimed in claim 1 , wherein the adjustment device is configured to deform the outer wheel ring during the rotation of the wheel.

21. The wheel as claimed in claim 1 , wherein a control device is configured such that the adjustment device may be actuated to drive a wheel in rotation.

22. A method for driving the wheel as claimed in claim 1 , in rotation, comprising: driving the wheel in rotation by adjusting the hub relative to the outer wheel ring, wherein the hub is adjustable in five degrees of freedom relative to the outer wheel ring.
