The Testing Of The Shock Absorber

- Oct 30, 2017-

In order to speed up the vibration of the frame and the body, to improve the ride comfort and comfort of the car, the car suspension system is usually equipped with shock absorbers, widely used in the car is a two-way cylinder shock absorber.


Shock absorber detection includes shock absorber performance test, shock absorber durability test, shock absorber double excitation test


The various types of shock absorbers for power test, friction test, temperature characteristics test


First, the car in the poor road conditions on the road after 10km parking, hand touch shock absorber shell, if not enough heat, indicating no resistance inside the shock absorber, shock absorber does not work. At this point, you can add the appropriate lubricants, and then test, if the shell heat, the shock absorber internal lack of oil, should add enough oil; otherwise, that shock absorber failure.


Second, press the bumper, and then release, if the car has 2 to 3 jump, then the shock absorber work well.


Third, when the car slow driving and emergency braking, if the car vibration is more intense, indicating a shock absorber problems.


Fourth, remove the shock absorber to its upright, and the lower end of the connection ring clamp on the vise, forced to pull the vibration pole several times, this time there should be a stable resistance, pull up (recovery) resistance should be greater than the If the resistance is unstable or no resistance, may be inside the shock absorber or valve parts damaged, should be repaired or replaced parts.
