Abstract

The invention relates to a crossmember for motor vehicle construction, having at least two modules that can be arranged one above the other, wherein each module has an inner side wall and an outer side wall, which are connected to one another at their upper ends by an upper wall and at their lower ends by a lower wall, wherein the upper wall of the lower module has, over the longitudinal extent thereof, a raised portion or depression, which engages in a complementary depression or raised portion of the lower wall of the upper module.

Claims

1. A crossmember for motor vehicle construction, having at least two modules that can be arranged one above the other, wherein each module has an inner side wall and an outer side wall, which are connected to one another at their upper ends by an upper wall and at their lower ends by a lower wall , wherein the upper wall of the lower module has, over the longitudinal extent thereof, a raised portion or depression, which engages in a complementary depression or raised portion of the lower wall of the upper module.

2. The crossmember as claimed in claim 1, wherein the at least two modules that can be arranged one above the other are designed as identical extruded profiles made from a metal, in particular from aluminum or an aluminum alloy, or from a plastic.

3. The crossmember as claimed in claim 1, wherein the raised portions are designed as tongues, which engage in the depressions, which are designed as complementary grooves.

4. The crossmember as claimed in claim 1, wherein raised portions are joined, in particular adhesively bonded, riveted or screwed, to the depressions.

5. The crossmember as claimed in claim 1, wherein at least one of the modules has opposite apertures in its side walls.

6. The crossmember as claimed in claim 5, wherein the aperture in the outer side wall has a smaller cross section than the aperture in the inner side wall.

7. The crossmember as claimed in claim 5, wherein a molded element, preferably made of foam, is arranged in the module, between the side walls, in the region of the apertures.

8. The crossmember as claimed in claim 7, wherein the molded element is provided with leadthroughs for supply lines, in particular for an energy supply, a control system, a hydraulic system, a cooling system etc.

9. The crossmember as claimed in claim 7, wherein a seal is arranged between the outer side wall and/or the inner side wall and the molded element.

10. The crossmember as claimed in claim 1, wherein it is designed as a bulkhead.

11. A bulkhead comprising a crossmember as claimed in claim 1.
