A kind of shock absorber spring pad and its processing technology

Abstract

This application relates to the technical field of auto parts, in particular to a shock absorber spring pad and its processing technology, including a detachably connected supporting body and a limiting body; the supporting body is set as an annular elastic body with a perforated hole in the middle The limiting body is set as an annular elastic body, which is fitted and connected to one side of the support body, and a limiting groove is arranged on the side of the limiting body away from the supporting body along the circumference, and one end of the shock absorber spring abuts against the limiting body. In the bit slot, the inner wall of the limiter is provided with a fixing part that penetrates into the through hole and connects with the support body. The spring pad of this application adopts a split structure, the support body is used as a force buffer, and the limit body has good wear resistance and extrusion resistance, and this combination greatly prolongs the service life of the spring pad. In the case of a part of the structure being damaged , the other part can still play a role, and at the same time only the damaged part needs to be replaced, and the other part can still be used, which greatly reduces the waste of materials and costs.

Description

technical field [0001] The present application relates to the field of auto parts, in particular to a shock absorber spring pad and its processing technology. Background technique [0002] In order to rapidly attenuate the vibration of the frame and the body and improve the ride comfort and comfort of the car, shock absorbers are generally installed on the car suspension system, and the double-acting cylinder shock absorber is widely used in cars. [0003] The shock absorber of a car is also called "suspension", which is composed of a spring and a shock absorber. The shock absorber is not used to support the weight of the body, but is used to suppress the shock when the spring rebounds after shock absorption and absorb the energy of road impact. The spring plays the role of alleviating the impact, changing "one impact with large energy" into "multiple impact with small energy", while the shock absorber gradually reduces the "multiple impact with small energy". A car with a...

AI Technical Summary

Problems solved by technology

Without a shock absorber, the rebound of the spring cannot be controlled. When the car encounters a rough road, there will be serious bounce, and the vibration of the spring up and down when cornering will also cause the loss of tire grip and tracking.

[0004] The upper and lower ends of the shock absorber spring are usually equipped with spring pads to protect and limit the spring, and move on the shock absorber rod together with the spring. During the long-term use of the shock absorber, the spring pad is often subject to a large extrusion force , and damage occurs, especially the lower spring pad. The lower spring pad in the related art has low structural strength and poor durability, and is easily distorted and deformed to be scrapped, which shortens the service life of the entire shock absorber and increases the frequency of replacement, which is very inconvenient.
