Automotive shock absorber

Suspension system due to the shock vibration is produced by the elastic element, in order to improve the automobile driving comfort, suspension and the elastic element parallel installation of shock absorber, for the attenuation of vibration, vehicle suspension system with damper is hydraulic shock absorber and its working principle is when the relative motion of the frame (or body) and the bridge between the vibration, shock absorber piston moving, the damper cavity of the oil will repeatedly from a cavity through different pore into another chamber.

Automobile shock absorber is used in the process of wearing parts, shock absorber work, good or bad, will directly affect the driving stationarity and other parts of life, therefore, we should make shock absorber often is in good working condition. The following method can be used to test whether the work of the vibration damper is good.

Modern automobile shock absorber mainly has two kinds of hydraulic and pneumatic. In which the universal use of hydraulic. Will be used in conjunction with the spiral spring.

Test Editor for shock absorber

1. To make the car drive 10km on the poor condition of roads on the road parking, using her hands to feel shock absorber shell, if isn't hot enough, no resistance in the shock absorber and shock absorber does not work. At this point, you can add the appropriate lubricating oil, and then the test, if the shell heat, then the vibration absorber inside the lack of oil, should add enough oil; otherwise, the vibration damper failure.
2 press the bumper, and then release, if the car has 2 ~ 3 jump, then the vibration damper work well.
3 when the car is moving slowly and emergency braking, if the car vibration is more severe, the vibration damper has a problem.
. remove the damper to the upright, and the lower end of the connecting ring clamped in a vise, straining to vibration damping rod several times, at this time should have a stable resistance, to pull (Restoration) of the resistance should be greater than the downward pressure resistance. If the resistance is not stable or no resistance, may is inside a shock absorber to lack of oil or valve parts damaged, repair or replacement of parts.
