Abstract

A motor vehicle body is disclosed which includes at least one rear wheel house and a reinforcing structure for connecting a shock absorber in the region of the wheel house. The reinforcing structure includes a reinforcing profile arranged on an outside of the wheel house facing a rear wheel, and extends with a spring plate connecting piece provided for fastening a spring plate from a lower side of the wheel house to an upper apex portion of the wheel house. The reinforcing profile located in the region of the upper apex portion of the wheel house includes a middle profile portion with a shock absorber connection, to which a shock absorber can be fastened with an end portion facing away from the rear wheel.

Claims

1. A motor vehicle body comprising:

a rear wheel house; and

a reinforcing structure including a reinforcement profile located on an outside of the wheel house facing towards a rear wheel, the reinforcing structure having a spring plate connecting piece configured to fasten a spring plate extending from a lower side of the wheel house toward an upper apex portion of the wheel house and a middle profile portion which comes to lie in the region of the apex portion, the middle profile portion including a shock absorber connection configured to be fastened with a shock absorber with an end portion facing away from the rear wheel,

wherein at least a portion of the reinforcing profile comprises a C- or U-profile like cross section and is connected to the outside of the wheel house with at least one lateral flange projecting towards an outside of the vehicle.

2. The motor vehicle body according to claim 1, wherein the reinforcing profile extends from the apex portion in vehicle longitudinal direction towards the back and is structurally connected to a rear end reinforcing structure with a rear profile portion.

3. The motor vehicle body according to claim 2, wherein the rear end reinforcing structure comprises at least one reinforcing plate which extends on an inside of the wheel house in vehicle longitudinal direction facing away from the rear profile portion of the reinforcing profile, and which supports itself in vehicle transverse direction on an outside of a rear end side member.

4. The motor vehicle body according to claim 3 comprising two reinforcing plates which in vehicle vertical direction are spaced from one another, which in vehicle longitudinal direction extend between a rear end rear wall plate and the wheel house and which in vehicle transverse direction extend between the side member and a side wall.

5. The motor vehicle body according to claim 3, wherein at least one flange of the reinforcing profile contacting the outside of the wheel house is arranged in vehicle vertical direction and in vehicle transverse direction at least in regions overlapping with a flange of the at least one reinforcing plate.

6. The motor vehicle body according to claim 1, wherein the reinforcing profile includes a front profile portion which substantially extends in vehicle vertical direction from the spring plate to the apex portion of the wheel house and is located at the front based on the travelling direction of the motor vehicle.

7. The motor vehicle body according to claim 1, wherein the middle profile portion of the reinforcing profile which comes to lie in the region of the apex portion of the wheel house substantially extends in vehicle longitudinal direction.

8. The motor vehicle body according to claim 7, wherein the shock absorber connection is formed on the middle profile portion projecting in vehicle transverse direction towards the outside.

9. The motor vehicle body according to claim 1, wherein the reinforcing profile located at the back based on the travelling direction of the motor vehicle comprises a rear profile portion, which substantially extends in vehicle vertical direction from the apex portion of the wheel house to a rear lower edge of the wheel house.

10. The motor vehicle body according to claim 9, wherein the rear profile portion comprises an curved section on its lower end projecting in vehicle transverse direction towards the outside, which supports itself in vehicle longitudinal direction on the outside of the wheel house.

11. A motor vehicle body comprising:

a rear wheel house;

a reinforcing structure including a reinforcing profile located on an outside of the wheel house facing towards a rear wheel, the reinforcing structure having a spring plate connecting piece configured to fasten a spring plate extending from a lower side of the wheel house toward an upper apex portion of the wheel house and a middle profile portion which comes to lie in the region of the apex portion, the middle profile including a shock absorber connection configured to be fastened with a shock absorber with an end portion facing away from the rear wheel, the reinforcing profile extending from the apex portion in vehicle longitudinal direction towards the back and is structurally connected to a rear end reinforcing structure with a rear profile portion,

wherein the rear end reinforcing structure comprises a profile ring enclosing a rear aperture of the motor vehicle.

12. The motor vehicle body according to claim 11, wherein the rear profile portion comprises a flange which in vehicle transverse direction projects towards the inside, and which is connected to the rear end reinforcing structure with a back side facing away from the travelling direction.

13. A motor vehicle with a motor vehicle body, the motor vehicle body comprising:

a rear wheel house;

a reinforcing structure including a reinforcing profile located on an outside of the wheel house facing towards a rear wheel, the reinforcing structure having a spring plate connecting piece configured to fasten a spring plate extending from a lower side of the wheel house toward an upper apex portion of the wheel house and a middle profile portion which comes to lie in the region of the apex portion, the middle profile portion including a shock absorber connection configured to be fastened with a shock absorber with an end portion facing away from the rear wheel, and the reinforcing profile located at the back based on the travelling direction of the motor vehicle comprises a rear profile portion, which substantially extends in vehicle vertical direction from the apex portion of the wheel house to a rear lower edge of the wheel house,

wherein the rear profile portion comprises an curved section on its lower end projecting in vehicle transverse direction towards the outside, which supports itself in vehicle longitudinal direction on the outside of the wheel house.

14. The motor vehicle according to claim 13, wherein the reinforcing structure has a profile which at least is C- or U-shaped bent or L-shaped angled portions in a plane formed by vehicle longitudinal direction and vehicle vertical direction and follows the contour of the wheel house.
