Shock absorbers are an important component of automotive suspension systems, and their internal structure is complex. The internal structure of shock absorbers mainly includes the following parts:
1. Cylinder body and piston
The cylinder block is the main body of the shock absorber, usually made of steel or aluminum alloy. The piston and piston rod are the core components of the shock absorber, and their motion state directly affects the working effect of the shock absorber. The piston is a cylindrical component that can move up and down in the cylinder, connecting the frame and wheels of a motorcycle.
2. Valves
Valves are used to control the flow and pressure of oil. There are extension valves and flow valves on the piston to control the flow of oil between the upper and lower chambers; The compression valve and compensation valve between the lower chamber of the working cylinder and the oil storage cylinder are used for the flow of oil between the lower chamber and the oil storage cylinder.
3. Spring
Springs are used to support the weight of the vehicle body and shock absorbers. The main function of springs is to help the piston move up and down smoothly. The hardness and length of the spring can be adjusted according to different needs to adapt to different road surfaces and driving conditions.
4. Oil
The shock absorber is filled with oil inside, and when the piston moves up and down, the oil will flow through the valve, creating damping effect. The magnitude of the damping effect depends on the flow speed of the oil and the degree of valve opening, which are controlled by the valves inside the shock absorber.
