Abstract

A load-bearing structural component of a motor vehicle body is provided. The structural component is designed as a cast component, and exhibits at least one suspension strut holding fixture and a bulkhead section, which are joined together as a single piece. The cast component is designed as a cast steel component of a fabricated front structural node.

First claim

What is claimed is:

1. A load-bearing structural component of a motor vehicle body, comprising:
a cast component that includes at least one suspension strut holding fixture and one bulkhead section, which are joined together as a single piece,
wherein the load-bearing structure is designed as a cast steel component;
a windshield support joined as a single piece with the suspension strut holding fixture; and
a wheel suspension strut joined as a single piece with at least one of the suspension strut holding fixture, the bulkhead and the windshield support, wherein the suspension strut holding fixture, bulkhead section, windshield support and wheel suspension strut form an at least regionally closed, box-like structure.

2. The load-bearing structural component according to claim 1 ,
wherein the windshield support is joined as a single piece with the bulkhead section.

3. The load-bearing structural component according to claim 1 , further comprising:
a wheel well section, which is joined as a single piece with at least one of the suspension strut holding fixture, the bulkhead section, the wheel suspension strut and the windshield support.

4. The load-bearing structural component according to claim 3 , wherein an end section of a drain channel is arranged between the bulkhead section, suspension strut holding fixture and wheel suspension strut, and designed as a single piece with at least one of the bulkhead section, suspension strut holding fixture and wheel suspension strut.

5. The load-bearing structural component according to claim 4 , wherein the windshield support transitions into the bulkhead section via a cover adjoining it.

6. The load-bearing structural component according to claim 5 , wherein at least one of the windshield support, the cover and the bulkhead section extend substantially parallel to the surface normal of the adjoining wheel suspension strut.

7. A motor vehicle body, comprising:
at least one longitudinal member;
a bulkhead;
at least one structural component designed as a cast steel component, the at least one structural component comprising:
at least one suspension strut holding fixture, a bulkhead section and a windshield support that are joined together as a single piece,

wherein, when the structural component is in its final assembly position, the bulkhead section forms a lateral elongation of the bulkhead;
a central windshield support protruding in the longitudinal direction of the vehicle, wherein the central windshield support is provided at the upper end of the bulkhead, and
wherein, in the final assembly position of the at least one structural component, the windshield support forms a lateral elongation of the central windshield support.

8. The motor vehicle body according to claim 7 , wherein the at least one structural component includes:
a wheel suspension strut, and wherein, in the final assembly position of the structural component, wherein the wheel suspension strut laterally borders a drain channel arranged upstream from the bulkhead in the traveling direction of the vehicle.

9. A motor vehicle, comprising:
a motor vehicle body including at least one longitudinal member and a bulkhead;
at least one structural component designed as a cast steel component, the at least one structural component comprising:
at least one suspension strut holding fixture, a second bulkhead section, a wheel suspension strut and a windshield support that are joined together as a single piece; and

a central windshield support protruding in the longitudinal direction of the vehicle, wherein the central windshield support is provided at the upper end of the bulkhead, and wherein, in the final assembly position of the at least one structural component, the windshield support forms a lateral elongation of the central windshield support.

10. A load-bearing structural component of a motor vehicle body, comprising:
a cast component that includes at least one suspension strut holding fixture and one bulkhead section, which are joined together as a single piece wherein the load-bearing structural component is designed as a cast plastic part which at least regionally is provided with at least one metal inlay;
a windshield support joined as a single piece with the suspension strut holding fixture; and
a wheel suspension strut joined as a single piece with the suspension strut holding fixture, the bulkhead section and the windshield support,
wherein the suspension strut holding fixture, the bulkhead section, the windshield support and the wheel suspension strut form an at least regionally closed, box-like structure.
