Abstract

The disclosure relates to a check rail for a wheel suspension of a wheel in a vehicle, wherein the wheel suspension may include a wheel carrier configured to support a wheel of a vehicle, the wheel carrier may include an elastic check rail body that may include a fiber-reinforced composite material with a first check rail end and a second check rail end, wherein the first check rail end is configured to be fastened to a structural body component of the vehicle, wherein the first check rail end is constructed without a bearing; and a pivot bearing on the second check rail end and configured to be rotatably fastened on the wheel carrier.

First claim

What is claimed is:

1. A check rail for a wheel suspension in a vehicle, wherein the wheel suspension comprises:
a wheel carrier configured to support a wheel of the vehicle, the wheel carrier comprising:
an elastic check rail body comprising a fiber-reinforced plastic composite material with a first check rail end and a second check rail end, wherein the first check rail end is configured to be fastened to a structural body component of the vehicle, wherein the first check rail end is constructed without a bearing; and
a pivot hearing on the second check rail end and configured to be rotatably fastened on the wheel carrier, wherein the structural body component comprises a clamping bearing, wherein the first check rail end is shaped for being introduced into the clamping bearing and is configured to be introduced on a front side into the clamping bearing;
wherein the pivot bearing is configured to carry the second check rail end in a direction of a longitudinal axis of the check rail and in a direction of a check rail transversal axis of the check rail in a traction-proof manner, a pressure-proof manner, or some combination thereof, and wherein the pivot bearing allows radial movements of the second check rail end in a certain range if forces act on the check rail transversely to the longitudinal axis of the check rail and transversely to the transversal axis of the check rail along a vertical axis of the check rail;
wherein the first check rail end comprises the front side as straight and configured to be introduced into the clamping bearing to make a self-locking clamping connection, the first check rail end comprises an oblique contact surface on the front side configured to be introduced into the clamping bearing to make a self-locking clamping connection, or some combination thereof.

2. The check rail according to claim 1 , wherein the first check rail end is configured to be elastically fastened or firmly clamped to the structural body component.

3. The check rail according to claim 1 , wherein the first check rail end is configured to be fastened to the structural body component by a clamping connection, a non-positive connection, by a firmly bonded connection, or by a positive connection.

4. The check rail according to claim 1 , wherein the first check rail end comprises at least one fastening opening, wherein a fastening means is configured to run through the at least one fastening opening.

5. The check rail according to claim 4 , wherein the fastener is a fastening screw or fastening rivet.

6. The check rail according to claim 1 , wherein the first check rail end is formed to be planar or comprises a section bent around a check rail transversal axis, wherein the section is configured to be placed on the structural body component and to be fastened to the structural body component.

7. The check rail according to claim 1 , wherein the first check rail end is shaped into a fastening tongue.

8. The check rail according to claim 1 , wherein at least one elastically deformable stop element on the first check rail end is configured to support an elastic deformation of the check rail about a check rail transversal axis.

9. The check rail according to claim 8 , wherein the first check rail end is shaped in a planar manner and the at least one elastically deformable stop element is a rubber plate configured to be placed under the first check rail end, configured to be placed on the first check rail end, configured to be set on the first check rail end, or some combination thereof, or wherein the first check rail end comprises a section bent about a transversal axis of the check rail and the at least one elastically deformable stop element is shaped as a wedge, plate, or some combination thereof configured to be inserted between the bent section and the structural body component.

10. The check rail according to claim 1 , wherein the check rail body comprises a first body width extending along the transversal axis of the check rail on the first check rail end, and wherein the check rail body further comprises a second body width extending along the transversal axis of the check rail on the second check rail end, and wherein the second body width is smaller than the first body width, or wherein the second body width and the first body width are equal.

11. The check rail according to claim 1 , wherein the check rail body comprises a first body thickness on the first check rail end, and wherein the check rail body further comprises a second body thickness on the second check rail end, and wherein the second body thickness is smaller than the first body thickness.

12. The check rail according to claim 1 , wherein the pivot bearing comprises one bearing casing or at least two bearing casings opposite one another.

13. The check rail according to claim 1 , wherein the pivot bearing is connected to the second check rail end by a by a non-positive connection, by a positive connection, by a screw connection, or by a clamping connection.

14. The check rail according to claim 13 , wherein the pivot bearing comprises a clamping bearing configured to receive the second check rail end.

15. The check rail according to claim 1 , wherein the pivot bearing is shaped from aluminum.

16. The check rail according to claim 1 , wherein the pivot bearing is formed by a barrel-shaped roller bearing.

17. The check rail according to claim 1 , wherein the check rail is constructed as a transversal rail of the vehicle.
