An improved vehicle suspension system for use on axles of trailers, trucks, and the like. A pair of wheels are individually rotatably mounted on stub axles attached to a pair of trailing arms which are connected to and extend radially rearwardly from a pair of pivot sleeves. The sleeves are pivotally mounted on brackets connected to the vehicle frame. A pair of spaced levers are attached to and extend radially outwardly from each of the pivot sleeves and rotate in unison with the trailing arms. An annular elastomer spring is located between a pair of metal end plates which are pivotally mounted on and located between the spaced levers. One of the end plates is connected to the lever by a hollow shaft and another shaft is connected to the other end plate and extends through the elastomer spring and into the hollow shaft to maintain the spring in axial alignment. The elastomer spring, in combination with the dual trailing arm and associated lever mounting arrangement, provides a balanced force on the vehicle tires and trailing arms during vehicle braking and upon the tires encountering road obstructions as well as during static conditions.

A vehicle suspension system adapted to be interposed between a vehicle frame and at least two wheels arranged one in advance of the other on a side of said vehicle frame; said suspension system including: (a) at least two axles on a side of said vehicle frame for independently rotatably mounting each of said wheels; (b) at least two trailing arms, each of said arms being attached at one end to a respective axle and extending forwardly from the axle wherein the number of said trailing arms does not exceed the number of axles; (c) at least two pivot means mounted on said vehicle frame and connected to the other end of said trailing arms for pivotally mounting said vehicle frame wherein the number of said pivot means does not exceed the number of axles; (d) lever means attached to and extending outwardly from each of said pivot means for pivotal movement with said pivot means means in relationship to movement of said trailing arms, with the length of said lever means being independent of the spacing between said axles; and (e) elastomer spring means extending between and pivotally mounted on said lever means for absorbing and balancing the forces exerted on said wheels particularly during braking and when encountering variations in the road surface.
