OD6mm Astm A519 Automotive Steel Tube For Automobile Shock Absorber

ASTM A519 Automotive Steel Tube For Automobile Shock Absorber

In the suspension system, the elastic element vibrates due to impact. In order to improve the driving smoothness

of the vehicle, the shock absorber is installed in parallel with the elastic element in the suspension. In order to

attenuate the vibration, the shock absorber used in the vehicle suspension system is mostly hydraulic shock

absorber. Its working principle is that when there is relative movement due to vibration between the frame

(or body) and the axle, the piston in the shock absorber moves up and down, The oil in the shock absorber

cavity repeatedly flows from one cavity through different pores into another 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 transformed into oil heat energy, which is absorbed and

emitted into the atmosphere by the shock absorber. When the oil channel section and other factors remain

unchanged, the damping force increases or decreases with the relative motion speed between the frame

and the axle (or wheel), and is related to the oil viscosity.

The shock absorber and elastic element undertake the task of mitigating impact and shock absorption.

Excessive damping force will deteriorate the elasticity of the suspension and even damage the shock

absorber connector. Therefore, the contradiction between elastic element and shock absorber should be adjusted.
