Air cylinder adaptive shock absorber In order to make the vibration of the frame and the body cab rapidly attenuates, improve the ride comfort and comfort of the car, the automobile suspension system is generally equipped with shock absorber or air bag vibration reduction. After the car runs 10km on the road with poor road conditions, it stops and touches the shell of the air cylinder shock absorber by hand. If it is not hot enough, there is no resistance inside the air cylinder shock absorber and the air cylinder shock absorber does not work. At this time, appropriate lubricating oil can be added, and then the test, if the shell heat, for the internal air cylinder shock absorber oil shortage, should add enough oil; Otherwise, the air cylinder shock absorber fails. adaptive shock absorbers is a special shock absorber, it is different from the general spring shock absorber, mainly with rubber compressed air to achieve, this kind of shock absorber has a unique advantage, in a lot of mechanical equipment used in the shock absorber must be used in order to really play a damping effect. Through the height control valve, the working height of the air spring can be maintained under any load, and the spring can also have different heights under the same load. Therefore, it is conducive to adapt to the requirements of a variety of structures.
