Vehicle dampener

Abstract

The present invention discloses a shock absorber for vehicle. It has internal cylinder body, external cylinder body, elastic body and shock-resisting ring. It is characterized by that between the described elastic body and the described external cylinder body a closed space is formed; said closed space is separated into first gap portion and second gap portion by using first partition body and second partition body which are integrally-formed on the described elastic body, in the first gap portion and second gap portion the hydraulic oil is injected respectively. The described vehicle shock absorber also has damping ring; said damping ring is a ring body with notch, on said ring body is set a hydraulic oil channel connected with the described first gap portion and second gap portion.

Description

technical field [0001] The invention relates to a shock absorbing structure of a vehicle, in particular to a vehicle shock absorber connecting a vehicle frame and an auxiliary frame. Background technique [0002] For the common structure of the shock absorber of an existing vehicle, reference may be made to "Anti-Vibration Structure of a Vehicle" disclosed in Chinese Patent Application 200410074600.9 and Japanese Patent Application Laid-Open No. 61-38341. The shock absorbing structure disclosed in Japanese Patent Application Laid-Open Sho 61-38341 includes an inner cylinder, an outer cylinder surrounding the outer periphery of the inner cylinder, and an elastic body sandwiched between the inner cylinder and the outer cylinder. The elastic body is equipped with a pair of hollow parts facing each other across the inner cylinder body, and a protrusion with a convex cross-section protruding from the inner cylinder side of the hollow part facing the outer cylinder side is formed,...

AI Technical Summary

Problems solved by technology

It has the disadvantage that the range of shock absorption and damping effect that it can provide is small, and it cannot well adapt to the shock absorption requirements of various driving conditions of the vehicle.

If the elastic modulus of the rubber is small, it will deform quickly when it is impacted. In this case, although it can meet the shock absorption requirements of the general driving state and has good comfort, it will be more comfortable when the vehicle is accelerated rapidly or suddenly. In the braking state, especially in the sudden braking state, there is a problem that the deformation of the rubber is too fast and the damping speed is too slow, so it is difficult to effectively suppress the front and rear vibration of the vehicle

However, if the elastic modulus of the rubber is designed to be large, then for the general driving state, there will be problems that the rubber deformation is too slow and the shock absorption speed is too fast, which will also have a negative impact on the comfort of the vehicle.
