Steering linkage arm assemblies

Abstract

A pivotal joint assembly including a socket housing having a cavity essentially of the shape of the bearing end of the stud member to receive the bearing member in operative relationship, said bearing member of said stud member being essentially cylindrical in shape and at least covered with sufficient elastomer to form a head and shoulder appearing elastomer ring thereon and to cause the elastomer in the head portion to be compressed 25 to 35% and preferably 27 to 32% in the assembled state. In a special embodiment, the pivotal joint assembly is adapted for use on track laying vehicles, such as tank tracks to give a housing to receive an inner pin or sleeve member having one or multiple bushings molded thereto, each bushing comprising a cylindrically elastomeric unit having a diameter larger than the diameter of the housing opening to receive the rubber and metal sleeve member and having a cylindrically elastomeric part of lesser diameter molded at each end of said larger cylindrical elastomeric unit to give said rubber and metal sleeve member the appearance of having one or multiple head and shoulder elastomeric units spaced thereon.
