How is the Air spring works?

Rubber air spring work, the cavity 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 cavity decreases, the stiffness of the spring increases, and the effective bearing area of the inner air column increases. At this moment, the bearing capacity of the spring increases.

When the vibration load decreases, the height of the spring increases, the volume of the cavity increases, the stiffness of the spring decreases, and the effective bearing area of the cavity air column decreases. At this time, the bearing capacity of the spring decreases. In this way, the air spring in an effective stroke, the air spring height, lumen volume, carrying capacity with the increasing and decreasing of the vibration load occurred smooth and flexible transmission, amplitude and vibration load control.

You can also increase, reduce the amount of inflation method to adjust the stiffness of the spring and the carrying capacity of the size, but also can be attached to the auxiliary chamber to achieve automatic control.
