Abstract:
An air suspension system for a vehicle having a chassis and front and rear axle housings; said system comprising;a) a lever arm having a forward end, a center section and a rear end, said lever arm being mounted on said chassis to extend transversely to, and rearwardly of said rear axle housing; b) a pivoting assembly for mounting the rear end of said lever arm in a pivoting mode to said chassis; c) an air spring mounted on said lever arm between said lever arm and said chassis to provide load support to said chassis; d) a bracket assembly including a roller bushing for mounting the front end of said lever arm in a caged position while enabling a shifting arcuate movement of said lever arm relative to said bushing; e) means for controlling the air pressure of said air spring; said air pressure controlling means being operatively coupled to said air spring which pressure is dependent on the vehicle loading; f) a pneumatic controlled hydraulic shock absorber mounted between said chassis and said axle housing to provide load support for chassis; and g) means for concurrently supplying pressurized air to said air spring and said shock absorber; whereby said air spring and shock absorber are adapted to be automatically sensitive and responsive to a load on the chassis.
