What is a car shock absorber?
In order to make the vibration of the frame and body quickly attenuate, improve the smoothness and comfort of car driving, the car suspension system is generally equipped with shock absorbers, the car is widely used on the two-way action cartridge shock absorber.
Failure test of car shock absorbers:
1, The car in poor road conditions on the road after 10km parking, touch the shock absorber shell by hand, if not hot enough, that the shock absorber internal no resistance, the shock absorber does not work. At this time, you can add the appropriate lubricant, and then test, if the shell is hot, the shock absorber internal lack of oil, should add sufficient oil; otherwise, the shock absorber failure.
2, Press the bumper hard, and then release, if the car has 2~3 jumps, it means that the shock absorber works well.
3, When the car is driving slowly and emergency braking, if the car vibration is more violent, it means the shock absorber has problems.
4, Remove the shock absorber will be upright, and the lower end of the connecting ring clamped in a vise, force pull pressure damping rod several times, at this time there should be a stable resistance, pull up the resistance should be greater than the resistance to the downward pressure, such as unstable resistance or no resistance, may be a lack of oil or valve parts damage inside the shock absorber, should be repaired or replacement parts.
