Vehicle vibration reducer with adjustable spring

Abstract

The invention discloses an automobile shock absorber with an adjustable spring. The shock absorber is composed of an inner cylinder and an outer cylinder. The end of the outer cylinder close to the inner cylinder extends outward to form a front limit ring. The inner cylinder The surface of the side away from the outer cylinder is provided with external threads, and the outer side of the inner cylinder is sequentially provided with a front spring washer, a spring, a rear spring washer, and a hardness adjusting nut, and the two ends of the spring are respectively connected to the front spring washer 1. The rear spring gasket is fixedly connected, and the hardness adjusting nut is provided with an internal thread part that cooperates with the external thread. The invention has a reasonable design. By adding a spring on the structural basis of the traditional two-way acting shock absorber, and using the hardness adjustment nut screwed with the inner cylinder to drive the spring to expand and contract in advance, the hardness can be adjusted by changing the preload of the spring. It is easy to operate and meets the hardness requirements of vehicles of different weights on elastic elements.

Description

technical field [0001] The invention relates to the technical field of automobile shock absorbers, in particular to an automobile shock absorber with adjustable springs. Background technique [0002] The shock absorber is an indispensable and important part of the vehicle suspension system. It is mainly used to suppress the shock when the shock-absorbing spring rebounds after absorbing the shock and the impact from the road surface. ride smoothness. 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. Shock absorber is too soft, automobile body can hop up and down, shock absorber can bring too great resistance too forcedly, cloggy bedspring works normally. In the process of refitting the suspension system, hard shock absorbers should be matched with hard springs, and the hardness of the springs is closely relate...

AI Technical Summary

Problems solved by technology

The barrel shock absorber mainly relies on the throttling effect of the valve to damp the suspension during the stretching movement, and most of them do not have springs; some barrel shock absorbers with additional springs cannot adjust the hardness of the spring on it, and cannot be adjusted according to Vehicle weight for stiffness adjustment
