The working principle of the shock absorber is that the oil in the shock absorber chamber repeatedly flows from one chamber to another through the pores. Through the friction between the oil and the hole wall and between the oil molecules, a damping force is formed on the vibration, and the energy of the vibration is converted into heat energy and released into the atmosphere.
The place where the shock absorber leaks oil is generally the oil seal washer. As long as the oil leak is not very serious, it will at most cause the deterioration of the vehicle's driving quality, and will not affect the driving safety.
Only when the oil leakage of the shock absorber is serious, it may affect the driving stability of the body, and the shock absorber needs to be replaced.
