Abstract

An apparatus for toe and/or camber adjustment for a running gear of a motor vehicle, having a tie rod and/or a link which can be fastened at one side to a bearing fixed with respect to the car body and at the other side by a bearing can be fastened to the wheel carrier of a wheel of the motor vehicle, wherein one bearing has an adjustment element which is in the form of an eccentric and which has an eccentric shaft, which eccentric shaft can be adjusted by an adjustment drive and is assigned safety bearings arranged on both sides of the eccentric.

First claim

The invention claimed is:

1. An apparatus for at least one of toe or camber adjustment for a running gear of a motor vehicle, comprising at least one of a tie rod or a link that is fastenable at one side to a bearing fixed with respect to a car body and at another side by a bearing to a wheel carrier of a wheel of the motor vehicle, one of said bearings has an adjustment element including an eccentric and an eccentric shaft that is adjustable by an adjustment drive, and safety bearings arranged on both axial sides of the eccentric and axially away from the eccentric are allocated to the eccentric shaft, further comprising a pair of spring-mounted bearings each located axially between a respective one of the safety bearings and the eccentric.

2. The apparatus according to claim 1 , wherein the safety bearings are formed as sliding bearings or rubber bearings.

3. An apparatus for at least one of toe or camber adjustment for a running gear of a motor vehicle, comprising at least one of a tie rod or a link that is fastenable at one side to a bearing fixed with respect to a car body and at another side by a bearing to a wheel carrier of a wheel of the motor vehicle, one of said bearings has an adjustment element including an eccentric and an eccentric shaft that is adjustable by an adjustment drive, and safety bearings arranged on both sides of the eccentric are allocated to the eccentric shaft, wherein the safety bearings are configured so that the safety bearings are not loaded during normal operation.

4. The apparatus according to claim 1 , further comprising an overload coupling arranged between the adjustment drive and the eccentric shaft.

5. The apparatus according to claim 4 , wherein the overload coupling has a spring element that is supported on one side on the eccentric shaft and on another side on the adjustment drive.

6. The apparatus according to claim 1 , wherein the adjustment drive is comprises an electric motor.

7. The apparatus according to claim 6 , wherein the electric motor is coupled with a transmission.

8. The apparatus according to claim 3 , wherein the safety bearings are formed as sliding bearings or rubber bearings.

9. The apparatus according to claim 3 , wherein the eccentric shaft is supported in radially spring-mounted roller bearings.

10. The apparatus according to claim 3 , further comprising an overload coupling arranged between the adjustment drive and the eccentric shaft.

11. The apparatus according to claim 10 , wherein the overload coupling has a spring element that is supported on one side on the eccentric shaft and on another side on the adjustment drive.

12. The apparatus according to claim 3 , wherein the adjustment drive is comprises an electric motor.

13. The apparatus according to claim 12 , wherein the electric motor is coupled with a transmission.

14. An apparatus for at least one of toe or camber adjustment for a running gear of a motor vehicle, comprising:
at least one of a tie rod or a link that is fastenable at one side to a bearing fixed with respect to a car body and at another side by a bearing to a wheel carrier of a wheel of the motor vehicle,
one of said bearings has an adjustment element including an eccentric and an eccentric shaft that is adjustable by an adjustment drive, and
safety bearings arranged on both axial sides of the eccentric and axially away from the eccentric are allocated to the eccentric shaft,
wherein the adjustment element includes a two-part split shaft extending along an axis of the eccentric shaft, and the two-part split shaft is located axially outside of the eccentric.

15. The apparatus according to claim 14 , wherein the eccentric shaft is supported in radially spring-mounted roller bearings.

16. The apparatus according to claim 14 , wherein the safety bearings are formed as sliding bearings or rubber bearings.

17. The apparatus according to claim 14 , further comprising an overload coupling arranged between the adjustment drive and the eccentric shaft.

18. The apparatus according to claim 17 , wherein the overload coupling has a spring element that is supported on one side on the eccentric shaft and on another side on the adjustment drive.

19. The apparatus according to claim 14 , wherein the adjustment drive is comprises an electric motor.

20. The apparatus according to claim 19 , wherein the electric motor is coupled with a transmission.
