Product Description

DESCRIPTION

Basically, an air-spring bellows is a column of air confined within a rubber and fabric container that looks like an automobile TIRE or two or three tires stacked on top of one another. The check valves admit additional air to the bellows from the air-supply tank to maintain vehicle height when the load is increased, and the leveling valves vent excess air from the bellows when the vehicle rises because of unloading. The vehicle thus remains at a fixed height regardless of load. Although an air spring is flexible under normal loads, it becomes progressively stiffer when compressed under an increased load. Air suspension was introduced on some luxury cars in the late 1950s, but it was dropped after several model years. Recently, new leveling systems have been developed for passenger cars, including air-adjustable rear shock absorbers; some air-spring systems operate without an air compressor.  

An air spring is a rubber and fabric bladder that holds air pressure to support a load and isolate passengers and cargo from the shock of motion caused by road irregularities. As the air pressure increases, the air spring can support more load while the spring rate increases. The larger the air spring, the greater the maximum load it can support. A collective set of air components necessary to allow for an air spring to function. A device that compresses and pressurizes air. Used to inflate air springs. The device which allows the transfer of air within the air system.
