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