Pneumatic:

Pneumatic shock absorber is a new type of shock absorber developed since 1960s. The utility model is characterized in that a floating piston is installed at the lower part of the cylinder barrel, and a closed gas chamber formed by the floating piston and one end of the cylinder barrel is filled with high-pressure nitrogen. A large section O-ring is installed on the floating piston, which completely separates oil and gas. The working piston is equipped with a compression valve and an extension valve which change the cross-sectional area of the channel with its moving speed. When the wheel jumps up and down, the working piston of the shock absorber moves back and forth in the oil fluid, resulting in an oil pressure difference between the upper chamber and the lower chamber of the working piston, and the pressure oil will push open the compression valve and the extension valve and flow back and forth. Because the valve produces large damping force to the pressure oil, the vibration is attenuated.

Hydraulic:

Hydraulic shock absorber is widely used in automobile suspension system. The principle is that when the frame and axle move back and forth, and the piston moves back and forth in the cylinder barrel of the shock absorber, the oil in the shock absorber housing will repeatedly flow from the inner cavity into another inner cavity through some narrow pores. At this time, the friction between the liquid and the inner wall and the internal friction of liquid molecules form a damping force to the vibration.

Automobile shock absorber is just like its name. The actual principle is not cumbersome, that is, to achieve the effect of “shock absorption”. Automotive suspension systems are generally equipped with shock absorbers, and bidirectional cylindrical shock absorbers are widely used in automobiles. Without the shock absorber, the rebound of the spring can not be controlled. When the car meets the rough road, it will produce serious bounce. When cornering, it will also cause the loss of tire grip and tracking due to the up and down vibration of the spring
