ABSTRACT:
An axle pivot assembly, used to mount an axle to a pair of brackets on a vehicle frame, includes an annular housing, an annular retaining nut, and a spherical bearing. The housing extends through an opening in the axle and has an annular rim on one end abutting against one side of the axle. The nut is fastened on an opposite end of the housing and clamps the axle between the housing rim and the nut. The spherical bearing has an outer annular ring and an inner annular spherical ring universally rotatably mounted within the outer ring. The outer ring seats against a shoulder defined within a bore in the housing and is retained therein by a snap ring. The axle pivot assembly also includes an elongated bolt and a pair of annular spacers. The bolt is fastened to and extends between the vehicle frame brackets and through an opening in the inner ring. The spacers are mounted over the bolt, disposed between and engaged with the vehicle frame brackets and have annular recessed portions on adjacent inner ends extending through the opening in the inner ring. The spacers confine the inner ring at a fixed location between facing shoulders defined by the annular recessed portions of the spacers and thereby limit the housing and the axle itself to pivotal movement about a fixed point relative to the vehicle frame brackets.
