Abstract

A method for producing a joining connection between a joint housing and at least one connection component including: providing a blank for the fabrication of the joint housing, and providing a connection component with a joint receptacle inserting the blank into the joint receptacle of the connection component and producing the joint housing through forming by cold extrusion of the inserted blank. An undercut positive-engagement joining connection is generated between the joint housing and the connection component during the cold extrusion process through transverse extrusion and/or upsetting. A chassis component has a structural component part with at least one joint receptacle formed as orifice and a joint housing for a joint device, which joint housing is inserted into this joint receptacle and fastened to the structural component part.

First claim

What is claimed is:

1 . A method for producing a joining connection between a joint housing and at least one connection component comprising:
providing a blank for the fabrication of the joint housing; providing the connection component having a joint receptacle formed as an orifice; inserting the blank into the joint receptacle of the connection component; and producing the joint housing by cold extrusion of the inserted blank, generating an undercut positive-engagement joining connection between the joint housing and the connection component during the cold extrusion process through transverse extrusion and/or upsetting.

2 . The method according to claim 1 , wherein the cold extrusion process is carried out in one step.

3 . The method according to claim 1 , wherein the blank has a circumferential annular collar configured as a stop when inserting the blank into the joint receptacle of the connection component and to transmit force during the cold extrusion.

4 . The method according to claim 3 , wherein the circumferential annular collar is not deformed during the cold extrusion and functions as positive-engagement element which, on one side of the connection component, overlaps an orifice rim of the joint receptacle, and wherein a further positive-engagement element that circumferentially overlaps the other orifice rim on the other side of the connection component is generated during cold extrusion by the transverse extrusion and/or upsetting.

5 . The method according to claim 4 , wherein a smaller overlapping of the orifice rim is generated with the positive-engagement element that overlaps the other orifice rim than with the circumferential annular collar.

6 . The method according to claim 1 , wherein a hollow body that is open at both of its ends is generated during the cold extrusion.

7 . The method according to claim 1 , wherein the blank and the connection component are formed from different materials.

8 . The method according to claim 1 , wherein the joint housing is a ball joint housing.

9 . A chassis component comprising:
a structural component part having at least one joint receptacle formed as orifice; a joint housing for a joint device, wherein the joint housing is inserted into the joint receptacle and fastened to the structural component part; and an undercut positive-engagement joining connection generated by transverse extrusion and/or upsetting formed between the joint housing and the structural component part such that the joint housing has positive-engagement elements ( 42 , 43 ) that circumferentially overlap orifice rims of the joint receptacle on both sides of the structural component part.

10 . The chassis component according to claim 9 , wherein the positive-engagement elements ( 42 , 43 ) overlapping the orifice rims of the joint receptacle have different overlaps of the orifice rims.

11 . The chassis component according to claim 9 , wherein a joint device is formed by the joint housing and a joint stud is received therein.

12 . The chassis component according to claim 10 , wherein a joint device is formed by the joint housing and a joint stud is received therein.
