Introduction:

20 540 789 / 20540789 air spring is a sealed container filled with compressed air, the use of gas compressibility to achieve its elastic effect. Air spring has the ideal non-linear elastic characteristics, the installation of height adjustment device, the body height does not change with the load changes, spring stiffness can be designed to be low, ride comfort is good.

principle:

20 540 789 / 20540789 air spring works in a closed pressure cylinder filled with inert gas or oil and gas mixture, so that the pressure inside the chamber several times higher than the atmospheric pressure or several times, the use of piston rod cross-sectional area is less than the cross-sectional area of the piston The resulting pressure difference to achieve the movement of the piston rod. Because the principle is fundamentally different, gas spring than ordinary spring has a very significant advantages: the speed is relatively slow, little change in dynamic force (usually in 1: 1.2 or less), easy to control.
