The air spring is filled with compressed air in a sealed container, and its elasticity is achieved by the compressibility of the gas. The air spring has the ideal nonlinear elastic characteristic. When the height adjustment device is added, the height of the body does not change with the increase or decrease of the load. The rigidity of the spring can be designed lower, and the riding comfort is good. But the air spring suspension structure is complex and the manufacturing cost is high.
When the air spring shock absorber works, the inner cavity is filled with compressed air to form a compressed air column. With the increase of the vibration load, the height of the spring decreases, the volume of the inner cavity decreases, the stiffness of the spring increases, and the effective carrying area of the air column in the inner cavity increases. At this point, the carrying capacity of the spring increases. When the vibration load is reduced, the height of the spring increases, the volume of the inner cavity increases, the stiffness of the spring decreases, and the effective carrying area of the air column in the inner cavity decreases, and the carrying capacity of the spring decreases at this time. In this way, the air spring in the effective stroke, height, and volume of the inner cavity of the air spring with increasing capacity and reducing occurred smooth transmission, flexible amplitude and vibration load of the efficient control of vibration load. The size of the rigidity and the bearing capacity of the spring can also be adjusted by the method of increasing and reducing the gas charging, and the auxiliary air chamber can also be attached to realize the automatic regulation.
The working principle of the air spring damper is confined to the inside of the pressure cylinder filled with inert gas or oil and gas mixture, the cavity is higher than atmospheric pressure several times or dozens of times, the cross-sectional area of the cross-sectional area of the piston rod of the piston to produce less than the pressure to achieve the movement of the piston rod. Due to the different fundamental principle, the gas spring than ordinary spring has the advantages of very significant: the speed is relatively slow, dynamic force changes little (within 1:1.2), easy to control; the disadvantage is relatively small volume of spiral spring, high cost, relatively short life.
