An aluminum joint ball pin assembly and its production process

Abstract

The application relates to an aluminum joint ball pin assembly and its production process. The aluminum joint ball pin assembly includes a pin body, a bearing shell is set in the middle of the pin body, and an elastic sleeve is set outside the bearing shell; the bearing shell includes a shell Body, both ends of the housing are provided with a ring of ribs, a mounting surface is provided between the two rings of ribs, the outer diameter of the mounting surface is smaller than the outer diameter of the ribs; The bottom is lower than the outer wall of the installation surface, and the outer wall of the installation surface is provided with an installation groove. The bottom of the installation groove is flush with the bottom of the entry groove. The end is aligned with the entry groove; the inner wall of the elastic sleeve is fixedly connected with a mounting block, the thickness of the mounting block along the radial direction of the elastic sleeve is adapted to the depth of the mounting groove, and the width of the mounting block is adapted to the width of the mounting groove; The ends of the block extend away from each other to the ends of the elastic sleeve. The application has the effects of cost saving and prolonging service life.

Description

technical field [0001] The application relates to the technical field of auto parts, in particular to an aluminum joint ball pin assembly and a production process thereof. Background technique [0002] The thrust rod assembly of the front balance rear suspension of heavy trucks is an important part of the suspension system, among which the joint ball pin assembly is particularly important. The service life of the joint ball pin assembly directly affects the service life of the vehicle. If it fails, even if it fails in time Replacement will also affect the service life of the axle and transmission system. [0003] Related technologies can refer to the Chinese utility model patent with the authorized announcement number CN211525323U, which discloses a joint bearing ball pin assembly with an integral structure, including a joint ball pin, and through holes are opened at both ends of the joint ball pin. The outer ring of the ball pin is provided with a bearing shell, and the ou...

AI Technical Summary

Problems solved by technology

However, during use, the elastic body is usually scratched and worn, which will affect the use of the entire joint ball pin assembly, and the elastic body is difficult to peel off from the bearing shell, and it is impossible to replace the elastic body alone, so that once If the elastic body is damaged, the undamaged joint ball pin and bearing shell also need to be replaced together, which has the disadvantage of wasting the cost of the joint ball pin and bearing shell and shortening the service life of the joint ball pin assembly
