Abstract

A connection comprising, a connecting part, a sleeve materially bonded to the connecting part and having a through-opening extending in a longitudinal direction, and a bolt connected to the sleeve and having a bolt shank and a bolt flange, the bolt being crimped with its bolt shank in the longitudinal direction in the through-opening of the sleeve, the bolt is arranged with its bolt flange in a recess arranged at a front face of the sleeve, characterized in that the sleeve is connected to the connecting part by its front face located at the front face end.

First claim

What is claimed is:

1. A connection comprising:
a connecting part;
a sleeve materially bonded to the connecting part and having a through-opening extending in a longitudinal direction; and
a bolt connected to the sleeve and having a bolt shank with a hole extending in a longitudinal direction of the bolt shank and a bolt flange, wherein the bolt is press-fitted with its bolt shank in the longitudinal direction in the through-opening of the sleeve, the bolt being arranged with its bolt flange in a recess arranged at a front face end of the sleeve,
wherein the sleeve is materially bonded to the connecting part with its front face located
at the front face end.

2. The connection according to claim 1 , wherein the bolt with its collar-shaped, radially outwardly projecting bolt flange is mounted at least partially circumferentially on a circumferential shoulder in the recess of the sleeve.

3. The connection according to claim 1 , wherein the recess arranged at the front face end of the sleeve encloses the through-opening of the sleeve.

4. The connection according to claim 1 , wherein the hole is a blind hole that extends in the longitudinal direction of the bolt between two front face ends of the bolt.

5. The connection according to claim 1 , wherein the hole is a through-hole that extends in the longitudinal direction of the bolt between two front face ends of the bolt.

6. The connection according to claim 1 , wherein the hole has an internal thread that extends only partially over the longitudinal extent of the bolt.

7. The connection according to claim 1 , wherein the bolt shank is knurled at least in sections on its outer lateral surface, in particular in an area adjacent to the bolt flange, and the knurled part is press-fitted into the through-opening.

8. The connection according to claim 1 , wherein the bolt is pressed into the through-opening in a non-rotatable manner.

9. The connection according to claim 1 , wherein the bolt flange is arranged in the recess in the longitudinal direction at a distance from the front face.

10. The connection according to claim 1 , wherein the sleeve is formed of a copper material and/or that the bolt is formed of steel.

11. The connection according to claim 1 , wherein the sleeve is friction-welded, in particular full-area friction-welded, in particular rotary friction-welded, to the connecting part with the front face located at the front face end.

12. The connection according to claim 1 , wherein a connection part with an opening is placed over the hole of the bolt and is clamped to the sleeve by a screw via the thread in the hole of the bolt, so that the connection part is in direct contact with the end of the sleeve distal to the recess.

13. The connection according to claim 12 , wherein the connecting part, the sleeve, the bolt and the connection part are encapsulated in a common housing, the connecting part and the connection part being guided out of the housing in a moisture-tight manner.
