AI Technical Summary
Technical Problem
Metal ball pin assemblies are prone to sealing failure during frequent grease lubrication, which in turn leads to wear and affects their service life.
Method used
The inner and outer sleeves and reinforcing ribs are made of polyurethane material, combined with tear-resistant sleeves and protective sleeves. Through self-lubricating properties, they reduce friction, disperse impact force, and ensure sealing and stability.
Benefits of technology
This effectively avoids frequent grease lubrication, reduces wear between the ball pin and the inner sleeve, and improves the service life and dynamic performance stability of the ball pin assembly.

Abstract
The utility model relates to a polyurethane ball pin assembly, and belongs to the technical field of ball pin assemblies. The polyurethane ball pin assembly comprises a mounting shell and a ball pin, the protection mechanism comprises an outer sleeve fixedly connected to the inner wall of the mounting shell, an anti-tearing sleeve is fixedly connected to the inner wall of the outer sleeve, an inner sleeve is fixedly connected to the inner wall of the anti-tearing sleeve, and the lower end of the surface of the ball pin is spherically hinged to the inner wall of the inner sleeve; due to the fact that the inner sleeve of the special polyurethane component has the good self-lubricating characteristic, abrasion between the ball head of the ball pin and the inner sleeve is reduced, frequent grease injection lubrication is avoided, the sealing effect between the ball pin and the inner sleeve is guaranteed, abrasion between the ball pin and the inner sleeve is reduced, the service life of the ball pin assembly is guaranteed, and the service life of the ball pin assembly is prolonged. Through the outer sleeve, the inner sleeve and the reinforcing ribs of the special polyurethane components, the impact force borne by the ball pin is dispersed, the stability and durability of the dynamic performance of the mounting shell are guaranteed, and then the service life of the ball pin assembly is prolonged.
