The shock absorber can relieve the impact of the road surface, quickly absorb the vibration generated during bumps, and restore the vehicle to normal driving conditions.
shock absorber, English shock absorber, is widely used in automobiles to accelerate the attenuation of the vibration of the frame and 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 reciprocate, and the shock absorber is used to suppress the jump of this spring.
The working principle of the shock absorber:
The elastic element in the suspension system vibrates due to the impact. In order to improve the driving comfort of the car, a shock absorber is installed in parallel with the elastic element in the suspension to attenuate the vibration. The shock absorbers used in the suspension system are mostly hydraulic shock absorbers. The working principle is that when there is relative movement between the frame (or body) and the axle, the piston in the shock absorber moves up and, the oil in the shock absorber chamber repeatedly flows from one chamber to another through different pores.
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 to 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 (or wheel), and is related to the oil viscosity.
