DESCRIPTION

Air springs are employed through the use of an air compressor which fills and empties the pliable air bladder. The load is not distributed to the rubber liner, which only serves to contain the gas; the weight is attached to a piston or bead plate, which is directly supported by the air with very little deflection. A self-leveling mechanism is common to keep the air spring's load stable, and occasionally a separate coil spring is incorporated into the design. Also available are electronic air spring systems that can monitor air pressure, filter compressor air (preventing damage to the rubber bellows), and a lock to keep air inside of the spring in case of compressor or air line failure.

What is an Air Bag Suspension System?

Before you can begin to identify clearly the pros and cons of an air bag suspension, you need to understand the design of such a system.

An air bag suspension system is powered by either an electric pump or compressor that forces air into rubber bags typically made out of polyurethane and textile-reinforced rubber.

A compressor inflates the air bags to a certain air pressure. It’s important to note that it’s the air inside the bag that does the work of a spring. (An air bag suspension should not be confused with a hydropneumatics suspension which uses pressurized hydraulic liquid instead of air.)
