Abstract

A stiffening element for a subframe of a motor vehicle, including a substantially horizontal section in order to confer rigidity to the subframe in the horizontal plane, and a substantially vertical section in order to confer rigidity to the subframe in the vertical plane, wherein the stiffening element is designed in such a manner that the stiffening element is arrangeable on the subframe above a steering mechanism.

First claim

What is claimed is:

1. A subframe and a stiffening element for the subframe of a motor vehicle, the subframe including two longitudinally extending portions that are spaced apart in a lateral direction, and the stiffening element being monolithic and comprising a substantially horizontal section that extends laterally between the two longitudinally extending portions of the subframe and confers rigidity to the subframe in a horizontal plane, a substantially vertical section that extends vertically and confers rigidity to the subframe in a vertical plane, and a curved section extending vertically between the horizontal section and the vertical section and extending horizontally from one longitudinally extending portion to the other longitudinally extending portion, wherein the stiffening element is arrangeable on the subframe above a steering mechanism.

2. The subframe and stiffening element as claimed in claim 1 , wherein the stiffening element is formed from a plastic.

3. The subframe and stiffening element as claimed in claim 1 , wherein the stiffening element is formed from a fiber-reinforced plastic.

4. The subframe and stiffening element as claimed in claim 1 , wherein the stiffening element is formed from metal.

5. The subframe and stiffening element as claimed in claim 1 , wherein the stiffening element is formed from steel or aluminum.

6. The subframe and stiffening element as claimed in claim 1 , wherein the stiffening element is arrangeable on the subframe above a stabilizer in order to support lateral stabilizer forces.

7. The subframe and stiffening element as claimed in claim 1 , wherein the stiffening element is releasably connected to the subframe.

8. The subframe and stiffening element as claimed in claim 1 , wherein the stiffening element is screwed to the subframe.

9. The subframe and stiffening element as claimed in claim 1 , wherein the stiffening element is connected in an integrally bonded manner to the subframe.

10. The subframe and stiffening element as claimed in claim 1 , wherein the stiffening element is adhesively bonded or welded to the subframe.

11. The subframe as claimed in claim 1 , wherein profile parts are provided laterally on the subframe in order to support the subframe and the stiffening element on a body of the motor vehicle.
