1K4014 Firestone For Truck And Trailer Air Ballon/ Air Suspension /Air Spring

OEM NUMBER

DESCRIPTION

AIR SPRING is basically a column of air confined within a rubber-and-fabric container shaped like a bellows. The spring action results from the compression and expansion of the air. When used on road vehicles, air springs can keep the vehicle at a constant standing height regardless of load.

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.

Air spring buses couldn’t be more perfect. It is the best suspension in terms of ride quality. No other spring are more comfortable. Adjustable height makes it possible to go over obstacles. Air springs have lower weight capacity, but this is hardly a factor when it comes to buses. Buses rarely get near the loading ceiling.
