Abstract
A crash structure for attachment to a front subframe for a motor vehicle is provided. The crash structure includes an attachment area and a stiffening structure that reinforces the crash structure in the attachment area for the front subframe. The stiffening structure connects the crash structure to the front subframe in a friction-locked and/or formfitting manner.
Claims16
A crash structure for attachment to a front subframe for a motor vehicle, wherein the crash structure has a hollow profile, and wherein the crash structure comprises:
- an attachment area;
- and
- a stiffening structure that is at least partially arranged inside the hollow profile and that reinforces the crash structure in the attachment area, the stiffening structure comprising:
- an intermediate element having a passage opening, wherein the intermediate element is located between the crash structure and the front subframe;
- and
- a connection element that passes through the passage opening of the intermediate element, wherein the connection element extends in a longitudinal direction of the crash structure, and connects the crash structure to the front subframe in a friction-locked manner;
- a first plate-shaped element that is placed in an active position having its substantially planar surface abutting a wall of the front subframe;
- and
- a second plate-shaped element permanently connected to the first plate-shaped element via the intermediate element, wherein the second plate-shaped element is arranged substantially parallel to and spaced apart from the first plate-shaped element.
A front subframe for a motor vehicle, the front subframe comprising:
- a first leg;
- a second leg;
- and
- a crash structure fixed to the first leg and the second leg, wherein the crash structure has a hollow profile, and wherein the crash structure comprises:
- an attachment area;
- and
- a stiffening structure that is at least partially arranged inside the hollow profile and that reinforces the crash structure in the attachment area, the stiffening structure comprising:
- an intermediate element having a passage opening, wherein the intermediate element is located between the crash structure and the front subframe;
- and
- a connection element that passes through the passage opening of the intermediate element, wherein the connection element extends in a longitudinal direction of the crash structure, and connects the crash structure to the front subframe in a friction-locked-manner;
- a first plate-shaped element that is placed in an active position having its substantially planar surface abutting a wall of the front subframe;
- and
- a second plate-shaped element permanently connected to the first plate-shaped element via the intermediate element, wherein the second plate-shaped element is arranged substantially parallel to and spaced apart from the first plate-shaped element.
