Applications
Air suspension is used in place of conventional steel springs in heavy vehicle applications such as buses and trucks, and in some passenger cars.
It is widely used on semi trailers and trains (primarily passenger trains).
The purpose of air suspension is to provide a smooth, constant ride quality, but in some cases is used for sports suspension.
Modern electronically controlled systems in automobiles and light trucks almost always feature self-leveling along with raising and lowering functions.
Although traditionally called air bags or air bellows, the correct term is air spring (although these terms are also used to describe just the rubber bellows element with its end plates).
The system comprises
1. a vulcanised rubber air spring at each wheel
2. an air compressor, which is typically located in the trunk (boot) or under the bonnet
3. a compressed air storage tank may be included for rapid "kneel", storing air at ~150psi (1000 kPa), note (1psi=6.89kPa)
4. a valve block which routes air from the storage tank to the four air springs via a series of solenoids, valves and many o-rings
5. an ECAS computer which communicates with the car's main computer the BeCM and decides where to route air pressure
6. a series of 6 mm air pipes which channel air throughout the system (mainly from the storage tank to the air springs via the valve block)
7. an air drier canister containing desiccant
8. height sensors ideally on all 4 vehicle corners based, typically, on resistive contact sensing to give an absolute height reference for each corner of the vehicle.

Characteristics & some benefits of air spring
When the vehicle is not loaded, they are soft, but as the load is raised, the stiffness improves by increasing the air pressure inside the chamber. As a result, when the vehicle is lightly loaded or completely loaded, it provides the best ride comfort. Whenever the load varies, the air pressure is varied to keep the vehicle’s height constant. By absorbing road shock, air springs improve vehicle stability. Air spring systems are made to increase load-carrying capacity, stability, and overall ride quality.
