Abstract

A connection of a suspension strut to a body of a motor vehicle is provided. Motor vehicles, and in particular passenger motor vehicles, have a suspension strut for each wheel. The lower end region of the suspension strut is joined to the wheel suspension, while the upper end region of the suspension strut is connected to the body of the motor vehicle. For this purpose, the upper end region of the suspension strut has a holder by which the suspension strut is connected to the body. The holder is detachably connected to a body element of the body that extends substantially in parallel with the longitudinal extent of the suspension strut in the flat connecting region.

First claim

What is claimed is:

1. A motor vehicle, comprising:
a bodywork element of a body of the motor vehicle;
a suspension strut having an upper end region; and
a holder configured for the upper end region of the suspension strut, the holder fastening the suspension strut to the body, and
wherein the holder is releasably attached to the bodywork element of the body that extends substantially in parallel with a longitudinal extent of the suspension strut in a planar attachment region,
wherein the planar bodywork element is composed of a sheet metal component which, in a screw-on region, is stiffened by a sheet metal reinforcement plate, and
wherein the sheet metal component and the sheet metal reinforcement plate have at least one common flange bearing against one another and are connected to one another in a planar manner.

2. The motor vehicle according to claim 1 , wherein the bodywork element in the planar attachment region extends substantially in a longitudinal direction and in a vertical direction of the vehicle.

3. The motor vehicle according to claim 1 , wherein the holder is releasably attached to the bodywork element exclusively by screws.

4. The motor vehicle according to claim 3 , wherein all of said screws are screwed in substantially in a transverse direction of the vehicle.

5. The motor vehicle according to claim 1 , wherein the sheet metal component forms at least part of a wheel arch shell, and the holder is releasably attached to the bodywork element exclusively by screws.

6. The motor vehicle according to claim 1 , further comprising: bushings, into which screws are screwed, wherein
the bushings are welded to the sheet metal component and/or to the sheet metal reinforcement plate.

7. The motor vehicle according to claim 6 , wherein the bushings extend at least between the sheet metal component and the sheet metal reinforcement plate.

8. The motor vehicle according to claim 7 , wherein the bushings are welded to the sheet metal reinforcement plate and/or to the sheet metal component.

9. The motor vehicle according to claim 8 , wherein the bushings, in the screw-in direction, are supported in a form-fitting manner on the sheet metal reinforcement plate or on the sheet metal component.

10. The motor vehicle according to claim 6 , wherein at least one of the bushings has a portion which protrudes into a matching clearance in the holder.

11. The motor vehicle according to claim 10 , wherein an external diameter of the at least one bushing, between the sheet metal reinforcement plate and the sheet metal component, is larger than in the portion that protrudes into the holder.

12. The motor vehicle according to claim 1 , wherein the holder is fastened to the planar bodywork element exclusively by two screws.

13. The motor vehicle according to claim 12 , wherein the two screws are disposed on mutually opposite sides of the suspension strut.

14. A motor vehicle, comprising:
a bodywork element of a body of the motor vehicle;
a suspension strut having an upper end region; and
a holder configured for the upper end region of the suspension strut, the holder fastening the suspension strut to the body, and
wherein the holder is releasably attached to the bodywork element of the body that extends substantially in parallel with a longitudinal extent of the suspension strut in a planar attachment region,
wherein the planar bodywork element is composed of a sheet metal component which, in a screw-on region, is stiffened by a sheet metal reinforcement plate, and
bushings, into which screws are screwed, wherein the bushings are welded to the sheet metal component and/or to the sheet metal reinforcement plate.

15. The motor vehicle according to claim 14 , wherein
the bodywork element in the planar attachment region extends substantially in a longitudinal direction and in a vertical direction of the vehicle.

16. The motor vehicle according to claim 14 , wherein
the holder is releasably attached to the bodywork element exclusively by screws.

17. The motor vehicle according to claim 16 , wherein
all of said screws are screwed in substantially in a transverse direction of the vehicle.

18. The motor vehicle according to claim 14 , wherein
the bushings extend at least between the sheet metal component and the sheet metal reinforcement plate.

19. The motor vehicle according to claim 18 , wherein
the bushings are welded to the sheet metal reinforcement plate and/or to the sheet metal component.

20. The motor vehicle according to claim 19 , wherein
the bushings, in the screw-in direction, are supported in a form-fitting manner on the sheet metal reinforcement plate or on the sheet metal component.
