Abstract

A suspension stop member, for positioning between a first, movable element and a second, relatively fixed element, such as between the frame and the axle of a vehicle, for resiliently absorbing suddenly applied shocks and stopping the relative movements of the elements, is formed of a generally pear-shaped, resilient tube having a generally circular opening. The tube has an upper, flat end portion, for fastening to the movable element, and a lower, flat end portion for engaging the second element. The sides of the outer surface of the tube are bulged outwardly from the upper end portion part way towards the lower end portion and then are tapered downwardly towards each other to join the lower end portion. The upper part of the surface defining the opening is generally flat and coextensive with said upper end portion. The thickness of the wall segment at the lower end of the stop member is considerably greater than the generally similar wall thicknesses of the remainder of the member. The member collapses downwardly, under a suddenly applied load that moves the elements together, to cause its side portions to bulge outwardly further and to absorb the load and to stop the relative mo…
