A shock absorber assembly and its buffer block structure

Abstract

The invention discloses a buffer block structure for a vibration reducer assembly. The buffer block structure comprises a top, a base, and a negative poisson ratio component arranged between the top and the base, wherein the negative poisson ratio component comprises multiple layers of negative poisson ratio modules; the negative poisson ratio modules comprise support layers and connecting layers connected with the support layers; the support layers and the connecting layers of the adjacent negative poisson ratio modules are connected; the negative poisson ratio modules comprise multiple negative poisson ratio units; and the negative poisson ratio units are hollow structures formed by the connecting layers enclosing the support layers. The invention further discloses a vibration reducer assembly. The vibration reducer assembly and the buffer block structure thereof are reasonable in structural design, can obtain anticipated nonlinear rigidity values, improve the vehicle driving smoothness, and further improve the capacity of the buffer block resisting the impact load.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a shock absorber assembly and a buffer block structure thereof. Background technique [0002] The shock absorber assembly is an important performance part of the vehicle, which plays a role in buffering road impact, damping suspension and body vibration. As one of the important components of the shock absorber assembly, the buffer block directly affects the effect of the shock absorber on alleviating shock and vibration, affects the handling stability and ride comfort of the vehicle, and its durability also directly affects The service life of the shock absorber assembly. [0003] In the prior art, most of the buffer blocks used in the shock absorber assembly are solid structures made of polyurethane materials. Due to factors such as material properties and unreasonable structural design, such buffer blocks often fail to achieve the desired nonlinear stiffness curve. req...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the traditional structural design of the buffer block is one of the reasons for the poor ride comfort and braking performance of the vehicle on the impact road.

At the same time, the impact resistance of the existing buffer block is not good. In the vehicle durability road test, the long-term impact may cause the buffer block to crack or break
