Abstract

A four point vehicular suspension system for a vehicle having left and right side frame members and spaced apart front and rear axles, comprising a plurality of lever beams having proximal and distal ends, a pair of which are each pivotally attached at their proximal ends, in spaced apart relationship, to each of the left and right frame members and attached at their distal ends to the front and rear axles, an expandable force-producing pneumatic bag disposed between each of the lever beams and the respective frame member to which the lever beam is pivotally attached, each bag being positioned between the proximal end and the distal end of each of the respective lever beams, and a source of air pressure and a valving system that is responsive to an unlevel position of the vehicle frame to selectively expand or contract the pneumatic bags to level the vehicle frame.
