ABSTRACT:
An air suspension system for tandem axles vehicles includes a pair of inboard, laterally-spaced air springs disposed within or below the vehicle frame each in communication with a separate reservoir compartment. The air springs are connected to a transverse tubular cross member at their upper ends, which may function as to the air reservoir compartments and are seated on the interior ends of transverse levers, each lever articulating on a floating walking beam. Each floating transverse lever may be pivotally connected at its outer end to the lower end of an outrigger bracket which is mounted at its upper end on the frame of the vehicle. A rubber spring preferably is interposed between the outer end of the transverse lever and the outrigger bracket.
Upper torque rods interconnect the tandem axles and the vehicle frame, while lower torque rods interconnect the frame support bracket and the tandem axles.
