Abstract

A subframe for a vehicle for supporting at least one wheel-controlling component, wherein the subframe has at least one shell element, wherein the subframe has or forms at least one mount section for the mounting of a transverse link element, wherein a first subsection of the mount section has or forms at least one first passage opening for receiving a fastening mechanism for the transverse link element, wherein a further subsection of the mount section is a section which is bent relative to the first subsection. Also disclosed is a method for producing a subframe.

First claim

1 . A subframe for a vehicle for supporting at least one wheel-controlling component, the subframe comprising:
at least one shell element; and at least one mount section for the mounting of a transverse link element, wherein a first subsection of the mount section has at least one first passage opening for receiving a fastener for the transverse link element, and wherein a further subsection of the mount section is bent relative to the first subsection.

2 . The subframe of claim 1 , wherein a bend axis of the bent section is oriented parallel to a vertical axis of the subframe.

3 . The subframe of claim 1 , wherein the mount section has or forms an embossment or a bead.

4 . The subframe of claim 3 , wherein the embossment or bead extends from the first subsection to the further subsection.

5 . The subframe of claim 3 , wherein the embossment or bead is arranged at a same height as the first passage opening along the vertical axis of the subframe.

6 . The subframe of claim 1 , wherein a thickness of the mount section is greater in a reinforcement region around the first passage opening than outside the reinforcement region.

7 . The subframe of claim 6 , further comprising a reinforcement element arranged in the reinforcement region and mechanically connected to the subframe.

8 . The subframe of claim 7 , wherein the reinforcement element is welded onto the subframe.

9 . The subframe of claim 1 , wherein the mount section has a weld seam in a region adjacent to the first passage opening.

10 . The subframe of claim 9 , wherein the weld seam extends parallel to a vertical axis of the subframe.

11 . The subframe of claim 1 , further comprising, as the fastener, a combination ribbed screw.

12 . The subframe of claim 1 , wherein a thickness of the mount section is greater in a reinforcement region around the first passage opening than outside the reinforcement region.

13 . The subframe of claim 12 , further comprising a reinforcement element arranged in the reinforcement region which is mechanically connected to the subframe.

14 . The subframe of claim 13 , wherein the reinforcement element is welded onto the subframe.

15 . The subframe of claim 1 , wherein the mount section has a weld seam in a region adjacent to the first passage opening.

16 . The subframe of claim 15 , wherein the weld seam extends parallel to a vertical axis of the subframe.

17 . The subframe of claim 1 , further comprising, as a fastener, a combination ribbed screw.

18 . A method for producing a subframe for a vehicle for supporting at least one wheel-controlling component, the method comprising:
providing a shell element and at least one mount section for mounting of a transverse link element, wherein a first subsection of the mount section is provided to have at least one first passage opening for receiving a fastener for the transverse link element, wherein a further subsection of the mount section is provided as a section which is bent relative to the first subsection.

19 . The method of claim 18 , wherein a thickness of the mount section is greater in a reinforcement region around the first passage opening than outside the reinforcement region.

20 . The method of claim 18 , wherein a weld seam is arranged adjacent to the first passage opening.

21 . The method of claim 18 , wherein the transverse link element is fastened to the subframe by a combination ribbed screw extending through the first passage opening.
