Aluminum joint ball pin assembly and production process thereof

Abstract

The invention relates to an aluminum joint ball pin assembly and a production process thereof. The aluminum joint ball pin assembly comprises a pin body, the middle of the pin body is sleeved with a bearing shell, and the bearing shell is sleeved with an elastic sleeve; the bearing shell comprises a shell body, the two ends of the shell body are each provided with a circle of blocking edge, an installation face is arranged between the two circles of blocking edges, and the outer diameter of the installation face is smaller than that of the blocking edges; an inlet groove is formed in each blocking edge, the groove bottom of the inlet groove is lower than the outer wall of the installation face, an installation groove is formed in the outer wall of the installation face, the groove bottom of the installation groove is flush with the groove bottom of the inlet groove, the two ends of the installation groove deviate from each other and extend to the two ends of the installation face, and the end of the installation groove is flush with the inlet groove; an installation block is fixedly connected to the inner wall of the elastic sleeve, the thickness of the installation block in the radial direction of the elastic sleeve is matched with the depth of the installation groove, and the width of the installation block is matched with the width of the installation groove; and the two ends of the installation block deviate and extend to the two ends of the elastic sleeve. The aluminum joint ball pin assembly and the production process thereof have the effects of reducing the cost and prolonging the 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
