Abstract

For the fastening of an adjustable spoiler wing of a motor vehicle, a fastening element is provided which is fastened to the outer tube of an adjusting cylinder and consists of a receiving element with a fit-on sleeve fastened thereto, the fit-on sleeve having a sleeve part with an external thread which can be screwed into a fastening nut inside the spoiler. After the fit-on sleeve has been screwed into the fastening nut by way of a tool engaging in a hexagon socket, the adjusting cylinder is screwed by means of a threaded pin on the receiving element into the fit-on sleeve.

Claims

1. Fastening element for a spoiler wing of a motor vehicle on an adjusting cylinder which adjusts the spoiler wing to a lifted and lowered position, comprising

a receiving element connected with an outer tube of the adjusting cylinder and having a molded-on centric threaded pin which is connected with a fit-on sleeve that directly carries the spoiler wing, wherein the spoiler wing is firmly held in a clamped-in manner between the fit-on sleeve and a fastening nut, and the receiving element has a centric elevation on its contact surface, which elevation receives cup springs in a centering manner and is supportingly situated opposite a plate of the fit-on sleeve.

2. Fastening element according to claim 1, wherein the plate of the fit-on sleeve has an edge-side collar-shaped recess which is provided on the outer edge and is supported on the face side of the outer tube of the adjusting cylinder.

3. Fastening element according to claim 2, wherein the fit-on sleeve has a centric sleeve part which is molded onto the plate and has an internal and external thread and a tool engagement or a hexagon socket and is constructed for the connection with the fastening nut by way of the external thread.

4. Fastening element according to claim 1, wherein the fastening nut is arranged in an indentation of the spoiler wing, which fastening nut has a flat contact surface with respect to the indentation as well as to the plate of the fit-on sleeve.

5. Fastening element according to claim 4, wherein the fastening nut is constructed to rest firmly against a spoiler wall of the spoiler wing.

6. Fastening element according to claim 1, wherein the cup springs arranged between the plate of the fit-on sleeve and the receiving element are supported on a snap ring so as to be spaced away from the bottom surface of the plate.

7. Fastening element according to claim 2, wherein the fastening nut is arranged in an indentation of the spoiler wing, which fastening nut has a flat contact surface with respect to the indentation as well as to the plate of the fit-on sleeve.

8. Fastening element according to claim 7, wherein the fastening nut is constructed to rest firmly against a spoiler wall of the spoiler wing.

9. Fastening element according to claim 3, wherein the fastening nut is arranged in an indentation of the spoiler wing, which fastening nut has a flat contact surface with respect to the indentation as well as to the plate of the fit-on sleeve.

10. Fastening element according to claim 9, wherein the fastening nut is constructed to rest firmly against a spoiler wall of the spoiler wing.

11. Fastening element according to claim 2, wherein the cup springs arranged between the plate of the fit-on sleeve and the receiving element are supported on a snap ring so as to be spaced away from the bottom surface of the plate.

12. Fastening element according to claim 3, wherein the cup springs arranged between the plate of the fit-on sleeve and the receiving element are supported on a snap ring so as to be spaced away from the bottom surface of the plate.

13. Fastening element according to claim 4, wherein the cup springs arranged between the plate of the fit-on sleeve and the receiving element are supported on a snap ring so as to be spaced away from the bottom surface of the plate.

14. A motor vehicle spoiler assembly comprising:

a fixed body part,

a spoiler wing supported on an adjusting cylinder for movement with respect to the fixed body part, and

a fastening arrangement for fastening the spoiler wing on the adjusting cylinder,

wherein the fastening element comprises a receiving element which is connected with an outer tube of the adjusting cylinder and has a molded-on centric threaded pin which is connected with a fit-on sleeve which directly carries the spoiler wing, the spoiler wing is held in a firmly clamped-in manner between this fit-on sleeve and a fastening nut, and the receiving element has a centric elevation on its contact surface, which elevation receives cup springs in a centering manner and is supportingly situated opposite a plate of the fit-on sleeve.

15. An assembly according to claim 14, wherein the plate of the fit-on sleeve has an edge-side collar-shaped recess which is provided on the outer edge and is supported on the face side of the outer tube of the adjusting cylinder.

16. An assembly according to claim 15, wherein the fit-on sleeve has a centric sleeve part which is molded onto the plate and has an internal and external thread and a tool engagement or a hexagon socket and is constructed for the connection with the fastening nut by way of the external thread.

17. An assembly according to claim 16, wherein the fastening nut is arranged in an indentation of the spoiler wing, which fastening nut has a flat contact surface with respect to the indentation as well as to the plate of the fit-on sleeve.
