A suspension linkage for an axle has hard mechanical oscillation stops that move relative to the vehicle frame as the axle travels vertically. The linkage uses thrust bearings to eliminate sideways movement of the axle that causes bounce steer. The linkage is a scissors linkage, having an upper link and a lower link joined together at a center pivot. The hard mechanical oscillation stops are carried by the linkage, as opposed to the vehicle frame, and thus move vertically with the axle.
1. An axle and suspension system for suspending the axle from a frame of a vehicle, comprising: an axle body; a thrust arm extending in a longitudinal direction between the axle body and the frame; a scissors linkage extending vertically between the axle body and the frame and being coupled to the axle body through a pivot bearing allowing oscillation of the axle body about a longitudinal axis; a spring resiliently coupling the axle body to the frame; left and right first oscillation stops on the linkage and left and right second oscillation stops...
