Rubber air spring is commonly known as air spring, pneumatic bladder, air bag, etc. It is a precision-designed rubber nylon bellows using inert gas (such as air, nitrogen, etc.) as the elastic medium. The air spring itself does not provide force or support load. It is a non-metallic spring that injects compressed air into a flexible closed container and uses the compressibility of air to achieve elastic effects. Air springs can be roughly divided into two categories: bladder type and diaphragm type. The bladder type air spring is designed into single layer, double layer and triple layer according to the needs. Two air springs can also be superimposed when needed; diaphragm air springs are There are two types: constrained membrane type and free membrane type. Air springs have excellent elastic properties. When used in vehicle suspension devices, they can greatly improve the dynamic performance of the vehicle, thereby significantly improving driving comfort. Therefore, air springs are widely used in automobiles and railway rolling stock. In addition, because air springs have many advantages compared with ordinary steel springs, they are also used in presses, shears, compressors, centrifuges, vibrating conveyors, vibrating screens, air hammers, and food machinery.

Characteristics of rubber air springs
Can be used for a long time. The deformation of the rubber membrane is small when the bladder air spring expands and contracts, so it has excellent durability.
Maintenance is extremely easy. There are no sliding parts and no oil supply is required.
Safety height can be lowered. Compared with other springs, the installation height can be lowered and a larger stroke can be obtained.
The spring constant is soft. It can gently bear larger loads and has unparalleled anti-shock effect.
Spring output force can be changed. The spring output force can be varied within a wide range by changing the internal pressure.
Height controllable. If used together with a height regulating valve, a certain height can always be maintained even if the load changes.
Has an attenuating effect. If the auxiliary air tank and throttle valve are used together, excellent attenuation effect can be obtained and the resonance amplitude can be reduced.
Easy to install.
