Shock Absorber

Applicable models

Shock Absorber is used to suppress the shock and impact from the road surface when the spring bounces after absorbing the shock. It is widely used in automobiles to accelerate the attenuation of the vibration of the frame and the body to improve the driving comfort of the automobile. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will also have reciprocating motion, and the Shock Absorber is used to suppress the jump of this spring.Tarzan auto parts---Our inventory includes all auto parts sold in the world, including Dongfeng, Sinotruk, Howo, FAW Honda, Toyota, Volkswagen, Volvo, etc. Welcome to buy.

Product details

In the suspension system, the elastic element is shocked and vibrates. In order to improve the ride comfort of the car, a Shock Absorber is installed in parallel with the elastic element in the suspension to attenuate the vibration. Its working principle is that when relative motion occurs between the frame (or body) and the axle, the piston in the Shock Absorber moves up and down, and the oil in the Shock Absorber cavity repeatedly flows from one cavity to another through different pores. Cavity. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vehicle vibration energy is converted into oil heat, which is then absorbed by the Shock Absorber and emitted into the atmosphere. When the oil channel cross-section and other factors remain unchanged, the damping force increases or decreases with the relative movement speed between the frame and the axle, and is related to the oil viscosity.
Shock Absorber and elastic components are responsible for the task of buffering and damping shock. Excessive damping force will deteriorate the elasticity of the suspension and even damage the Shock Absorber connector. Therefore, it is necessary to adjust the contradiction between the elastic element and the shock absorber.
(1) During the compression stroke, the Shock Absorber has a small damping force in order to give full play to the elastic effect of the elastic element and alleviate the impact. At this time, the elastic element plays a major role.
(2) During the extension stroke of the suspension, the Shock Absorber should have a large damping force to quickly absorb the shock.
(3) When the relative speed between the vehicle bridge and the vehicle bridge is too large, the Shock Absorber is required to automatically increase the fluid flow rate, so that the damping force is always kept within a certain limit to avoid excessive impact load.
The cylindrical Shock Absorber is widely used in the automobile suspension system, and it can play a shock absorption effect in both compression and extension strokes. It is called a two-way-acting Shock Absorber. There is also a new type of Shock Absorber, which includes inflatable Shock Absorber and resistance. Adjustable Shock Absorber.
