Embodiment Construction

[0028] The drawing shows an exemplary embodiment of a motor vehicle body-in-white structure 1 , the area of ​​the motor-vehicle body-in-white structure 1 being indicated by a rectangle R, within which a first cross member 3 and a second cross member 5 are arranged. In the illustrated exemplary embodiment of the motor vehicle body-in-white structure 1 , the first cross member 3 and the second cross member 5 are designed identically, so only the first cross member 3 will be described in detail below. The design of the first transverse beam 3 also applies to the second transverse beam 5 .

[0029] In a further embodiment of the motor vehicle body-in-white structure 1 two different cross members 3 , 5 or only one cross member or more than two identical or different cross members can be provided.

[0030] The cross member 3 provided for the underbody region of the motor vehicle body-in-white structure 1 has an arcuate middle part 7 which bridges the central tunnel region of the mot...

Abstract

The invention relates to a cross-member (3, 5) for the base region of a motor vehicle body shell structure (1), characterised in that at least some sections of said cross-member (3, 5) comprise a light metal or light metal alloy, preferably aluminium or an aluminium alloy, or preferably magnesium or a magnesium alloy, and in that at least some sections of this are produced by forging.

Description

technical field [0001] The invention relates to a cross member for the underbody region of a motor vehicle body-in-white structure according to the preamble of claim 1 , a method for producing the cross member according to the preamble of claim 7 , and a The motor vehicle body-in-white structure described in the preamble of claim 8. Background technique [0002] Beams of the type discussed herein are well known. German laid-open publication DE 10 2010 018 638 A1 describes a support structure for a seat cross member, which is formed from an elongated profile extending in the transverse direction of the vehicle, which is made of sheet steel and is mold-hardened by thermoforming. Alternatively, it is also known to configure the cross member at least partially as a cast part, tube or extruded profile part. The disadvantage of these configurations is that in the event of a side impact, the cross member still needs to be improved, especially with regard to its mechanical strengt...
