DESCRIPTION

An air suspension system is a style of vehicle suspension that's powered by an electric pump or compressor that pumps air into flexible bellows that are typically made out of a textile-reinforced type of rubber. Additionally, describes air suspension as a replacement to the leaf suspension or coil spring system with airbags composed of polyurethane and rubber. A compressor inflates the bags to a certain pressure in order to behave like springs. Air suspension also differs from hydropneumatic suspension because it uses pressurized air instead of pressurized liquid.

Is air suspension good for off-road? Yes, due to the very nature of air suspension being regulated with differing air pressures, you can often feel like you are gliding over rough terrain without even feeling it. Using air suspension limits damage and giving you and your passengers a more comfortable journey.

Air suspension is quite a modern concept when it comes to making motor vehicles ride in a more comfortable manner and was originally developed for use on bicycles back in 1901.

A vehicle that has modern air suspension fitted generally has a feeling of gliding over regular pot-holes and bumps and ditches on and off-road.

To achieve this there are rubber bellows fitted to each wheel. Each bellow is filled with air that is regulated using a compressor or pump that is governed and powered by the vehicle.

Some air suspended vehicles have adjustable air suspension that can allow the owner to change the actual ride height of their vehicle. This is especially useful when parking on an uneven surface or needing extra clearance to clear an obstacle while off-road.

As the vehicle is moving the shock absorbers have sensors built into them that send a signal to the compressor which in turn inflates or deflates the bellow, this all happens in the space of milliseconds.
