AIR SPRING FOR A HEAVY-DUTY VEHICLE WITH DAMPING FEATURES

摘要

An air spring for a heavy-duty vehicle axle/suspension system includes a bellows chamber operatively connected to a piston chamber. An opening is disposed between the bellows chamber and the piston chamber in order to allow fluid to communicate between the bellows chamber and the piston chamber. The cross-sectional area of the opening and the volumes of the bellows chamber and the piston chamber are tuned in order to optimize the damping characteristics of the air spring.
