The suspension of the automobile equipped with the resistance adjustable shock absorber generally uses the air spring with variable stiffness as the elastic element. The principle is that if the air pressure of the air spring increases, the pressure in the shock absorber gas chamber also increases, and the throttle aperture of the oil changes due to the change of pressure, so as to achieve the goal of changing the damping stiffness. The shock absorber is a vulnerable part in the use of the car, and the work of the shock absorber will directly affect the smoothness of the car and the life of other parts, so we should make the shock absorber often in good working condition.
The following methods can be used to check whether the shock absorber is working well.
1. Make the car stop after driving 10km on the road with poor road conditions, and touch the shock absorber shell with your hand. If it is not hot enough, it indicates that there is no resistance inside the shock absorber and the shock absorber does not work. At this time, you can add the appropriate lubricating oil, and then the test, if the shell is hot, it is the lack of oil inside the shock absorber, should add enough oil; Otherwise, it indicates that the shock absorber fails.4. Remove the shock absorber upright, and the lower end of the connection ring clamped on the pliers, pull the pressure damping rod several times, at this time there should be stable resistance, pull up (recovery) resistance should be greater than the resistance to the downward pressure, such as unstable or no resistance, may be the shock absorber internal oil or valve parts damaged, should be repaired or replaced parts.
