Cross-member configuration for a motor vehicle
A cross-member configuration for a motor vehicle has a basic member for receiving functional elements, and a body cross-member. The basic member is fastened to the body cross-member via holding elements. The holding elements have, on the body cross-member side, a stepped connecting region which is connected to a connecting region which is configured in a complementary manner thereto on the body cross-member. In addition, it is provided that the connecting regions each have at least two stepped surfaces which bear against one another when holding elements are connected to the body cross-member.
1 . A cross-member configuration for a motor vehicle, the cross-member configuration comprising:
a body cross-member having a connecting region;
holding elements each having a stepped connecting region on a body cross-member side, said stepped connecting region being configured complementary to said connecting region and connected to said connecting region on said body cross-member, said connecting region and said stepped connecting region each having at least two stepped surfaces bearing against one another; and
a basic member for receiving functional elements and fastened to said body cross-member by said holding elements.
2 . The cross-member configuration according to claim 1 , wherein at least one of said stepped surfaces of said holding elements and of said body cross-member each have a respective passage opening formed therein, said passage openings being aligned with one another when said holding elements are connected to said body cross-member.
3 . The cross-member configuration according to claim 1 , further comprising a connecting bracket, two of said holding elements are connected to each other in a transverse direction of the motor vehicle via said connecting bracket.
4 . The cross-member configuration according to claim 2 , wherein said holding elements each have a top cord and a bottom cord and a stiffening element which is disposed between said top cord and said bottom cord.
5 . The cross-member configuration according to claim 1 , wherein:
said stepped connecting region has a step; and
said body cross-member has depressions formed therein in which said step of said stepped connecting region of said respective holding element engages in each case such that a recessed configuration is produced, and said holding elements are welded to said basic member.
6 . The cross-member configuration according to claim 1 , further comprising a strut, said basic member being fastened to a longitudinal center tunnel of the motor vehicle via said strut.
7 . The cross-member configuration according to claim 1 , wherein said basic member is a supporting tube curved in some regions.
8 . The cross-member configuration according to claim 1 , further comprising a bracket connected to said basic member, said basic member fastened on a longitudinal end side via said bracket directly, or indirectly via a mating bracket, to an A-pillar of the motor vehicle.
9 . The cross-member configuration according to claim 1 , further comprising tab elements disposed on said body cross-member and form one of said stepped surfaces of said connecting region on said body cross-member side.
10 . The cross-member configuration according to claim 1 , wherein said body cross-member is a cowl.
11 . The cross-member configuration according to claim 2 , wherein said holding elements are screwed to said body cross-member through said passage openings.
12 . The cross-member configuration according to claim 3 , wherein said connecting bracket has recesses formed therein and configured in a complementary manner to an outer contour of said basic member and in said recesses said basic member engages with a form fit.
13 . The cross-member configuration according to claim 4 , wherein said top cord forms a first stepped surface and said bottom cord forms a second stepped surface.
14 . The cross-member configuration according to claim 13 , wherein said holding elements each have a sleeve element disposed on said body cross-member side between said top cord and said bottom cord and is substantially aligned with said passage opening in said second stepped surface.
15 . The cross-member configuration according to claim 1 , wherein said basic member has a cross section varying in a longitudinal direction.
16 . The cross-member configuration according to claim 8 , wherein said bracket has a recess formed therein and is of complementary design to an outer contour of said basic member and in which said basic member engages with a form fit.
17 . A motor vehicle, comprising:
a cross-member configuration, said cross-member configuration including:
a body cross-member having a connecting region;
holding elements each having a stepped connecting region on a body cross-member side, said stepped connecting region being configured complementary to said connecting region and connected to said connecting region on said body cross-member, said connecting region and said stepped connecting region each having at least two stepped surfaces bearing against one another; and
a basic member for receiving functional elements and fastened to said body cross-member by said holding elements.
