Abstract

The invention relates to a support ( 2, 3 ) used as a vehicle component and comprising a longitudinal extension which corresponds to a multiple of the transverse extension thereof. Said support ( 2, 3 ) comprises a reinforced transverse profile section. For this purpose, the support ( 2, 3 ) comprises at least one reinforced element ( 7, 8 ) which follows the longitudinal extension of the support ( 2, 3 ), is connected to the support in a positive and material fit manner and in a tension and shear-resistant manner, with the insertion of a separation layer ( 12 ) between the longitudinal extension of the support ( 2, 3 ).

First claim

The invention claimed is:

1. A support used as a vehicle component, the support comprising:
a longitudinal extension having a plurality of transverse extensions thereof, forming a transverse profile section;
the support comprising a first support and a second support, both supports being arranged to enclose a cavity
the transverse profile section of at least the first support having a substantially U-shaped cross-sectional geometry with a bottom connecting two side arms of the support;
at least the first support further comprising at least one reinforcing element along the longitudinal extension of the support;
the reinforcing element being connected to the first support in a positive or material fit manner, or in a tension- and shear-resistant manner;
a separating layer between the reinforcing element and the first support in the longitudinal extension of the first support; and
the reinforcing element only connected to the bottom and not attaching to the side arms of the U-shaped cross section and not attaching to the second support.

2. The support of claim 1 , wherein the reinforcing element is configured as an insert and is connected to an inner side of the bottom of the first support.

3. The support of claim 1 , wherein the reinforcing element comprises a transverse profile section.

4. The support of claim 1 , wherein the first support comprises a first weldable material and the reinforcing element comprising a second material which can be welded to the first material, and the reinforcing element is connected by several welding spots produced by spot welding to the first support.

5. The support of claim 4 , wherein the first support is made of a first metal material, and the reinforcing element is made of the same or another metal material which can be welded to the first material.

6. The support of claim 1 , wherein the separating layer extends over the entire surface of the reinforcing element facing the first support and is not needed for connecting the reinforcing element to the first support.

7. The support of claim 6 , wherein the spacing between reinforcing element and first support caused by the separating layer is at least largely constant over the longitudinal extension of the reinforcing element outside of a plurality of connection spots between reinforcing element and first support.

8. The support of claim 7 , wherein the separating layer is configured as an adhesive layer.

9. The support of claim 8 , wherein the adhesive layer is a layer which is cured under exposure to heat.

10. The support of claim 1 , wherein the first support is a portion of the vehicle component comprising an additional support.

11. The support of claim 1 , wherein the first support is a portion of a transmission carrier.
