A new type of shock absorber that can effectively avoid the eccentric wear of the connecting rod

Abstract

The invention provides a novel absorber capable of effectively avoiding eccentric abrasion of a connecting rod. The novel absorber solves the problem that when an existing absorber is used, the connecting rod is prone to eccentric abrasion. The novel absorber comprises the connecting rod, a guider and a recovery buffering block, wherein the connecting rod penetrates through an inner cylinder barrel of the absorber. At least two threads with semi-circular cross sections are machined on the surface of the connecting rod from the lower end to the upper portion. The inner cylinder barrel is composed of an upper inner cylinder barrel body and a lower cylinder barrel body which are connected through a circular nut. A thread of the circular nut is matched with the threads on the connecting rod. The two end faces of the circular nut are each provided with a groove, wherein the depth of each groove is 3 mm, the width of each groove is equal to the thickness of the inner cylinder barrel wall, and the grooves can be matched with the inner cylinder barrel and can keep sealing. According to the novel absorber, the eccentric abrasion of the connecting rod is effectively prevented, abrasion to the connecting rod is relieved, and therefore the service life of the absorber is prolonged.

Description

technical field [0001] The invention relates to an automobile shock absorber, in particular to a novel shock absorber capable of effectively avoiding eccentric wear of a connecting rod. Background technique [0002] The shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jumping. [0003] Hydraulic shock absorbers are widely used in automobile suspension systems. The principle is that when the frame and the axle do reciprocating relative motion, and the piston compresses and moves in the cylinder barrel of the shock absorber, the piston moves downward, and the oil in the working cylinder enters through the circulation valve and the compression valve under pressure. In the upper cha...

AI Technical Summary

Problems solved by technology

During the working process, under the guidance of the guider, the connecting rod drives the piston to perform a reciprocating linear motion of compression and recovery in the inner cylinder (working cylinder); the connecting rod mainly rubs against the guide bushing of the guider part and exists in each During the stroke, and the installation position of the locomotive shock absorber determines the non-vertical movement of the shock absorber connecting rod, which has a certain lateral force, which intensifies the mechanical eccentric wear and accelerates the wear of the shock absorber connecting rod
