ABSTRACT:
A universal joint pivot assembly exhibiting extended life and capable of being inexpensively manufactured. Bushings for receiving trunnion journals are provided with a plurality of upstanding bosses formed by a cold forging process. The boss surfaces are inclined to generate a conical surface, and the ends of the journals are formed at a matching angle. In a preferred embodiment the bosses are comprised by ridges which terminate short of the center of the bushing to form a cavity for receiving an unmachined protrusion at the journal center.
