Abstract: The present invention comprises a complete suspension system for multiple axle vehicles, including a single axle suspension structure, a tandem axle suspension structure wherein road and tire excitations of each axle are isolated from the opposing axle and from the sprung mass or vehicle frame, and a third structure interconnecting the tandem axles with articulated load equalizing rocker beams which are separately trunnioned in the suspension structure supported by said tandem axles. Both the single axle and the tandem axle suspension structures employ spherically shaped, pressure resistant, elastomeric spring means formed with cup shaped seats which, in turn, exhibit a varying spring rate upon said elastomeric spring means being subjected to load.

Abstract: This invention includes an elastomerically resilient load equalizing means interposed between the adjacent ends of pairs of leaf springs on each of opposite sides of a multiple axle vehicle. The load equalizing means functions (1) to resiliently equalize a varying load between its opposing axles; and (2) to isolate the excitations of each adjacent spring end and its supporting axle from both the cross shaft of the frame (sprung mass), and from the opposing adjacent spring end and its respective supporting axle, through deflection of pressure resistant elastomers. The interconnection of said adjacent spring ends and said resilient equalizing means is restrained against disconnection at rebound.
