Automobile self-resetting vibration absorber

Abstract

The invention relates to an automobile self-resetting vibration absorber which comprises a working cylinder assembly and a piston rod assembly; the working cylinder assembly comprises an oil storage cylinder assembly and an inner working cylinder; the working cylinder assembly is filled with hydraulic oil; an air bag is arranged between the oil storage cylinder assembly and the inner working cylinder, and sleeves the peripheral surface of the inner working cylinder in the axial direction; the two axial ends of the air bag are in sealing fit with the peripheral surface of the inner working cylinder; an air cavity is formed between the middle part of the air bag and the peripheral surface of the inner working cylinder; the piston rod assembly is arranged in the inner working cylinder; the piston rod assembly comprises a piston rod; the piston rod is sleeved with a guider, a first locating casing pipe, a second locating casing pipe and a restoring valve assembly from left to right sequentially; the first locating casing pipe is fixed to the inner wall of the inner working cylinder in an interference manner; and the second locating casing pipe can slide horizontally along the inner working cylinder. The automobile self-resetting vibration absorber is simple in structure, can achieve self-resetting and is good in resetting effect, and good controllability and driving stability of anautomobile are realized.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, in particular to automobile self-resetting shock absorbers. Background technique [0002] With the development of the automobile industry, consumers have higher and higher requirements for automobiles. The application of shock absorbers is also ubiquitous, but conventional shock absorbers are basically only responsible for vibration reduction, and there is no corresponding technical support for customers' higher requirements such as "automatic reset and simultaneous vibration reduction". The scope of application is very limited. The existing passenger car steering damper is also only responsible for steering damping, but because there is no two-way reset function, it needs to be manually rotated and reset when returning to the position, which is time-consuming and labor-intensive, and the general steering damper also has the following defects: (1) The oil storage cylinder adopts a singl...

AI Technical Summary

Problems solved by technology

The existing passenger car steering damper is also only responsible for steering damping, but because there is no two-way reset function, it needs to be manually rotated and reset when returning to the position, which is time-consuming and labor-intensive, and the general steering damper also has the following defects: (1) The oil storage cylinder adopts a single-cylinder structure. The oil storage cylinder is also a working cylinder. The piston cannot move relative to the working cylinder. During the working process, it is easy to deform the cylinder due to splashing sand and stones, and the piston will appear due to the deformation of the working cylinder. Stuck phenomenon; (2) The spring used is usually a helical spring with a round wire diameter. When it is compressed axially, it is easy to bend and eccentrically wear the inner wall of the working cylinder, resulting in premature failure of the product and noise during operation.
