Material angle
From the perspective of generating damping materials, shock absorbers are mainly hydraulic and pneumatic, and there is also a variable damping shock absorber.

Hydraulic

Hydraulic shock absorbers are widely used in automobile suspension systems. The principle is that when the frame and the axle reciprocate and the piston reciprocates in the cylinder of the shock absorber, the oil in the shock absorber shell repeatedly flows from the inner cavity through some narrow pores into the other. An inner cavity. At this time, the friction between the liquid and the inner wall and the internal friction of the liquid molecules form a damping force against vibration.

Inflatable

Inflatable shock absorber is a new type of shock absorber developed since the 1960s. Its structural feature is that a floating piston is installed in the lower part of the cylinder, and a closed air chamber formed between the floating piston and one end of the cylinder is filled with high-pressure nitrogen. A large-section O-ring seal is installed on the floating piston, which completely separates oil and gas. The working piston is equipped with a compression valve and an expansion valve that change the cross-sectional area of ​​the channel according to its moving speed. When the wheel bounces up and down, the working piston of the shock absorber reciprocates in the oil, so that an oil pressure difference is generated between the upper cavity and the lower cavity of the working piston, and the pressure oil pushes the compression valve and the expansion valve to flow back and forth. Because the valve produces a relatively large damping force on the pressure oil, the vibration is attenuated.
