Problems solved by technology

The rubber ball pin at the end and the traditional ball pin assembly of the V-rod with the ball hinge structure in the middle adopt polyurethane sliding structure. The ball pin of this structure has a short life and poor reliability under heavy load and impact load. Now it is usually used overall vulcanization The structure of the ball pin assembly, the service life of this ball pin is longe

Example Embodiment

[0013] The present invention will be further described below in conjunction with the drawings and embodiments.

[0014] figure 1 , 2 The sliding ball pin assembly 6 includes a ball pin metal joint bearing and an end cover 5. The ball pin metal joint bearing includes a ball pin 1 and a friction pair outer ring 2. The middle of the ball pin 1 is spherical, and the outer side of the ball pin 1 is assembled There is a matching friction pair outer ring 2, which forms a friction pair in the form of universal motion. The outer circumferential surface of the friction pair outer ring 2 is vulcanized with a layer of polyurethane 3. The polyurethane 3 connects the friction pair outer ring 2 with the two ends. The cover 5 is vulcanized into one body. The spherical surface of the ball pin 1 is provided with oil storage grooves 11 distributed in a cross pattern.

[0015] The outer ring 2 of the friction pair has a split structure, and the outside is fixed as a whole by a spring lock ring 4.

Abstract

The invention relates to a sliding ball pin assembly applicable to a thrusting rod of a heavy loading vehicle balance rear suspension, which comprises a ball pin metal joint bearing and end covers, wherein the ball pin metal joint bearing comprises a ball pin and a friction pair outer ring; the middle part of the ball pin is spherical; the outside of the ball pin is assembled with the friction pair outer ring matched with the outside of the ball pin; the ball pin and the friction pair outer ring form a friction pair in a universal moving mode; the twisting and deflecting of the thrusting rod can be converted into relative movement of the friction pair; and the outer circumferential surface of the friction pair outer ring is provided with a layer of polyurethane which sulfates the friction pair outer ring and two end covers into a whole. When the ball pin performs the actions and bears impact, the polyurethane elastic body only bears extrusion; because the stress is simplified and the ball pin only bears the pressure subjected by the elastic body, the service life is greatly prolonged.

Description

technical field [0001] The invention relates to a sliding ball pin assembly for automobiles, in particular to a sliding ball pin assembly suitable for a thrust rod of a rear balance suspension of a heavy-duty truck. Background technique [0002] The thrust rod assembly of the balanced rear suspension of heavy-duty trucks is an important stressed part of the suspension system. Its high damage rate has always been a headache for vehicle and component manufacturers. The main part of the damage is the ball pin assembly. The rubber ball pin at the end and the traditional ball pin assembly of the V-rod with the ball hinge structure in the middle adopt polyurethane sliding structure. The ball pin of this structure has a short life and poor reliability under heavy load and impact load. Now it is usually used overall vulcanization The structure of the ball pin assembly, the service life of this ball pin is longer than the traditional structure, but the overall vulcanized rubber ball ...
