A stop assembly for predetermining the maximum downward travel distance or rebound of a vehicle axle/suspension system includes an adjustment cam. A chain for heavy-duty applications, or a woven nylon strap for lighter-duty applications, is immovably attached at its lowermost end to each suspension assembly beam of the axle/suspension system. An uppermost end of the chain is immovably attached to the cam, which in turn is pivotally captured in a bracket assembly immovably attached to the vehicle frame. An easily accessible adjustment bolt passes through the bracket assembly and bears on the cam, so that upon rotation of the bolt using a wrench or similar tool, the chain, and in turn the suspension assembly beam and the axle captured in the beam, can be selectively vertically repositioned by the pivoting cam to predetermine the maximum system rebound during vehicle operation.
A rebound stop assembly for limiting the downward rebound travel distance of a vehicle axle suspension system, said axle suspension system including a pair of transversely spaced suspension assemblies, each one of said pair of suspension assemblies including a longitudinally extending beam, said beams each being pivotally mounted on and depending from a frame of said vehicle, said beams further capturing a transversely extending axle having at least one wheel mounted on each end of said axle, one of said rebound stop assemblies being incorporated into each one of the pair of suspension assemblies, each one of said rebound stop assemblies including elongated vertically extending stop means, a first end of said stop means being immovably attached to a selected one of said beam and said axle, and a second end of the stop means being immovably attached to said vehicle frame, wherein the improvement comprises:
