The principle of shock-absorbing products mainly includes the following aspects:
The working principle of shock absorbers
The main function of shock absorbers is to suppress the shock when the spring rebounds after shock absorption and the impact from the road surface, so as to improve the driving smoothness of the car. In the automobile suspension system, the shock absorber is usually a hydraulic shock absorber, and its working principle is as follows:
Hydraulic shock absorber: When the frame (or body) and the axle move relative to each other, the piston in the shock absorber will move up and down. The up and down movement of the piston will cause the oil in the shock absorber to flow from one cavity through the pores to another cavity. In this process, the friction between the oil and the pore wall and the internal friction between the oil molecules will generate damping force, converting the vibration energy into heat energy, and dissipating it into the atmosphere through the shock absorber.
Double-tube hydraulic shock absorber: This shock absorber is divided into two cylinders: the oil storage cylinder and the working cylinder. The piston rod is connected to the frame and can move up and down, while the lower end of the shock absorber is connected to the axle and remains fixed. The valve on the piston controls the flow of oil, thereby adjusting the damping force.
The relationship between shock absorbers and springs
Shock absorbers and springs work together in the car suspension system to jointly undertake the tasks of buffering and shock absorption. The spring is mainly responsible for storing energy, while the shock absorber reduces the bumps caused by uneven roads by consuming heat energy and improves driving comfort. Both are indispensable and together ensure the smooth driving of the car.
