ABSTRACT:
An axle suspension assembly for a low-bed trailer wherein the frame is formed of I-beams at each side thereof and each I-beam has an intermediate portion sloping upwardly and rearwardly between a low central portion and a higher rear portion. The customary trailing arm or equalizing beam is pivotally mounted on the web of this sloping portion of the I-beam utilizing a bushing assembly. Basically, the bushing assembly includes two pivot brackets which are bolted to opposite sides of the web and which carry, by way of a resilient bushing a bushing core through which a fastener may pass so as to clamp opposite arms of a yokelike forward portion of the trailing arm to the bushing core. The bushing core passes through an opening formed in the web with the opening being elongated in a fore and aft direction whereby the bushing assembly may be adjusted so as to accurately position the mounted axle transversely of the trailer frame. Each pivot bracket includes a collar and in a preferred embodiment of the bushing, separate bushings are pressed into the collars with the bushings being bonded to separately formed bushing cores.
