Abstract
Abstract A suspension assembly for triaxle installation having front, central and rear beams connected to the front, central and rear axles. The front and rear beams are oscillating beams pivotally mounted on pedestals depending from the vehicle frame. The central beam is free floating but is pivotally connected to the front beam and bears upwardly against the rear beam for equalization of loads through the beams to the three axles. All beams are rubber-bushing mounted for self-tracking. The front beams serve as radius rods for the central axle, eliminating the need for a separate radius rod to be connected to the central axle.
