Abstract

A motor vehicle has a self-supporting body which has a passenger compartment, with two longitudinal members, with two rear reinforcing struts which run in a V-shaped manner and are fastened at the front ends thereof to lateral longitudinal member portions of the two longitudinal members. The lateral longitudinal portions run below the passenger compartment. The two reinforcing struts are arranged at the rear ends thereof on a receiving component. The receiving component is a plastics/metal hybrid component which is composed of an open, shell-shaped metal component and of a fiber-reinforced reinforcing plastics component. The plastics component is integrated in the metal component and reinforces the metal component.

First claim

What is claimed is:

1. A motor vehicle with a self-supporting vehicle body which has a passenger compartment, comprising:
two longitudinal carriers which run on a floor of the vehicle body and which extend from a vehicle front section over the floor of the passenger compartment into a vehicle rear;
two rear reinforcing struts which run in a V-shaped manner and are fastened at respective front ends to respective lateral longitudinal carrier sections of the two longitudinal carriers, said respective lateral longitudinal carrier sections running below the passenger compartment;
a receiving component on which respective rear ends of the two reinforcing struts are arranged, wherein
the receiving component is a plastic and metal hybrid component comprising an open, shell-shaped metal component and a fiber reinforced plastic reinforcing component,
the fiber reinforced plastic reinforcing component is integrated into the metal component and reinforces the metal component,
the fiber reinforced plastic reinforcing component has two arms which run in a V-shaped manner and are connected to one another in one piece on a connecting section of the plastic reinforcing component, and
reinforcing webs with annular fastening sections are configured in one piece on an underside of the fiber reinforced plastic reinforcing component of the receiving component.

2. The motor vehicle as claimed in claim 1 , wherein
the plastic reinforcing component has a shell-shaped upper part, an outer face of which corresponds to an inner face of the shell-shaped metal component.

3. The motor vehicle as claimed in claim 1 , wherein
the annular fastening sections are connected via connecting webs to a circumferential outer edge of the shell-shaped upper part of the plastic reinforcing component.

4. The motor vehicle as claimed in claim 3 , wherein
through openings are configured in the annular fastening sections of the plastic reinforcing component.

5. The motor vehicle as claimed in claim 4 , wherein
a thread for a screw connection is integrated into the respective through openings of the plastic reinforcing component for fastening the respective end of the reinforcing strut.

6. The motor vehicle as claimed in claim 4 , wherein
the connecting section of the receiving component is spaced apart in a vertical direction by a predefined height from respective flange-shaped fastening sections at respective free ends of the respective arms.
