1. Two methods are usually used to buffer the sliding of one shaft tube in another shaft tube: one is called hydraulic shock absorption, which uses special hydraulic oil;
2. The other is called pneumatic shock absorption, which uses pressurized nitrogen. The shock absorber moves in two directions: when the wheel sinks due to load or braking, the shock absorber is pressurized; when the car returns to its original load, the shock absorberChina adjustable hydraulic shock absorbers manufacturer is decompressed. The principle of the shock absorber is actually very simple;
3. When it is pressurized, the lower pressure tube connecting the wheels rises and pushes the piston into the other shaft tube connected to the carriage; there is a standard small hole on the piston, and an oil pressure nozzle is installed on the hole, and the lubricant passes through the oil pressure nozzle. And play the role of damping the shock absorber rising;Motorcycle Rear Suspension Shock Absorbers
4. On the contrary, the wheels return to their original positions under the pressure of the suspension spring.
