Abstract

A spring plate for supporting a vehicle suspension spring, with a surface facing toward the vehicle suspension spring and with at least one support point, wherein the spring plate has a region which extends from the surface in the direction of the vehicle suspension spring and forms the support point, and wherein a sheet-metal element acting as a corrosion protection element is fastened to the extended region and is in contact with the vehicle suspension spring in all operating states.

First claim

What is claimed is:

1. A spring plate configured to support a vehicle suspension spring, the spring plate comprising:
a surface facing toward the vehicle suspension spring and with at least one support point;
a region that extends from the surface in the direction of the vehicle suspension spring and forms the support point; and
a sheet-metal element configured to act as a corrosion protection element, the sheet-metal element fastened to the region and configured to contact the vehicle suspension spring in all operating states.

2. The spring plate of claim 1 , wherein the sheet-metal element consists essentially of zinc or of a zinc alloy.

3. The spring plate of claim 1 , wherein the sheet-metal element includes limbs that are bent around the region to fasten the sheet-metal element.

4. The spring plate of claim 1 , wherein the spring plate consists essentially of plastic.

5. The spring plate of claim 4 , wherein the region is formed as a one-piece construction with the spring plate and the spring plate is produced by injection molding.

6. The spring plate of claim 1 , wherein the spring plate consists essentially of metal.

7. The spring plate of claim 6 , wherein the region is formed as a one-piece construction with the spring plate and the spring plate is produced by casting.

8. The spring plate of claim 6 , wherein the region is formed as a one-piece construction with the spring plate and is produced by shaping the spring plate.

9. A spring plate configured to support a vehicle suspension spring that is coiled around a longitudinal spring axis, with the vehicle suspension spring having a length that extends along the longitudinal spring axis, the spring plate comprising:
a surface configured to face the vehicle suspension spring and with at least one support point, wherein the longitudinal spring axis is normal to the surface;
a region that extends from the surface towards the vehicle suspension spring and forms the support point, with the region being configured to receive the vehicle suspension spring in a manner whereby the vehicle suspension spring is transverse to and extends across the region; and
a sheet-metal element configured to act as a corrosion protection element, the sheet-metal element fastened to the region and configured to contact the vehicle suspension spring in all operating states.

10. The spring plate of claim 9 wherein the region is radially spaced apart from an outer sidewall of the spring plate.

11. The spring plate of claim 9 wherein the region is curved to receive an outer surface of the vehicle suspension spring.

12. The spring plate of claim 9 comprising an end stop disposed on and protruding from the surface, wherein the end stop is in direct contact with an axial end of the vehicle suspension spring, with the end stop being annularly spaced apart from the region on the surface.

13. The spring plate of claim 9 wherein the sheet-metal element includes limbs that are bent around the region and fasten the sheet-metal element to the region, wherein the region is integral with the spring plate such that the region and the spring plate are a one-piece construction.

14. A spring plate configured to support a vehicle suspension spring, the spring plate comprising:
a surface configured to face the vehicle suspension spring, wherein the surface includes a channel that extends in a circular or semi-circular direction;
a region that forms a support point for the vehicle suspension spring, wherein the region is comprised of a strip of material that extends across the channel, transverse to the circular or semi-circular direction of the channel, with the strip of material being elevated relative to a bottom of the channel; and
a sheet-metal element configured to act as a corrosion protection element, the sheet-metal element fastened to the region and configured to contact the vehicle suspension spring in all operating states.

15. The spring plate of claim 14 wherein the region is radially spaced apart from an outer sidewall of the spring plate.

16. The spring plate of claim 14 wherein the region is curved to receive an outer surface of the vehicle suspension spring.

17. The spring plate of claim 14 comprising an end stop disposed on and protruding from the surface, wherein the end stop is in direct contact with an axial end of the vehicle suspension spring, with the end stop being annularly spaced apart from the region on the surface.

18. The spring plate of claim 14 wherein the sheet-metal element includes limbs that are bent around the region and fasten the sheet-metal element to the region, wherein the region is integral with the spring plate such that the region and the spring plate are a one-piece construction.

19. The spring plate of claim 14 wherein the surface comprises an aperture at a bottom of the channel beneath the region.

20. The spring plate of claim 14 wherein the channel extends on both sides of the region.
