Method for manufacturing a bearing shell assembly, and bearing shell assembly for a ball joint
View Patent ↗A method for manufacturing a bearing shell assembly for a ball joint includes the following steps: a) a bearing shell having a plastic extension is produced; b) a spring element is arranged in a region of the plastic extension; and c) the spring element is fastened to the bearing shell by deformation of the plastic extension. The invention further relates to a bearing shell assembly for a ball joint, including a bearing shell and a spring element, the spring element being non-detachably connected with the bearing shell.
1. A method for manufacturing a bearing shell assembly for a ball joint comprising the following steps:
a) a bearing shell having a plastic extension is produced;
b) a spring element is arranged in a region of said plastic extension;
c) said spring element is fastened to said bearing shell by deformation of said plastic extension; and wherein an external diameter of said plastic extension is widened during said deformation in step c), and wherein said spring element is a plate spring or an assembly of several plate springs.
2. The method according to claim 1 , wherein said bearing shell and said plastic extension are produced as an integral injection-molded part.
3. The method according to claim 1 , wherein said plastic extension is produced in step a) as a substantially hollow cylindrical extension having a free axial end.
4. The method according to claim 1 , wherein said spring element is fastened to said bearing shell in step c) by cold deformation of said plastic extension.
5. The method according to claim 1 , wherein said spring element has an opening for said plastic extension, said spring element being placed onto said bearing shell in step b) so that said spring element surrounds said plastic extension.
