Abstract

A housing for an energy store is arranged on the floor of a vehicle body. The housing has a cover, a bottom, and a peripheral frame. Fastening components are provided on a side transverse section of the frame that is at the rear in the vehicle longitudinal direction, on which fastening components the front ends of two stiffening braces extending in the shape of a V are arranged.

First claim

What is claimed is:

1. A motor vehicle, comprising:
a vehicle body having a passenger cell;
longitudinal carriers which run on a floor of the vehicle body and extend from a vehicle front section over the passenger cell into a vehicle rear;
two rear reinforcing struts which run in a V-shaped manner, rear ends of the two reinforcing struts being arranged on the floor of the vehicle rear via a receiving component, wherein the two rear reinforcing struts lie in a horizontal plane;
a housing for an energy store arranged on the floor of the vehicle body, wherein the housing has a cover, a floor and a peripheral frame; and
fastening sections provided on a rear lateral transverse section of the peripheral frame, wherein
front ends of the two reinforcing struts which run in the V-shaped manner are respectively arranged on the fastening sections.

2. The motor vehicle as claimed in claim 1 , wherein the housing has:
(i) a central housing section, or
(ii) a central housing section and a rear housing section, or
(iii) a front housing section, a central housing section and a rear housing section.

3. The motor vehicle as claimed in claim 1 , wherein
the rear lateral transverse section of the frame is a frame part which is of U-shaped or V-shaped configuration.

4. The motor vehicle as claimed in claim 1 , wherein
the rear lateral transverse section of the frame is manufactured from a light metal or a steel sheet shell design.

5. The motor vehicle as claimed in claim 2 , wherein
the fastening sections are provided on the frame part of the rear housing section or on the central housing section if a rear housing section of the housing is absent.

6. The motor vehicle as claimed in claim 1 , wherein
the fastening sections are projecting flange sections.

7. The motor vehicle as claimed in claim 1 , wherein
the receiving component is fastened to the floor of the rear region of the vehicle body in a perpendicularly or rearwardly and upwardly inclined manner.

8. The motor vehicle as claimed in claim 1 , wherein
the fastening sections for the front ends of the reinforcing struts are spaced apart from lateral longitudinal carriers of the housing in the vehicle transverse direction.
