RAILCAR CONSTANT CONTACT SIDE BEARING ASSEMBLY

摘要

A constant contact side bearing assembly for a railcar including a housing with wall structure defining a central axis for the side bearing assembly and a multipiece cap. The cap is arranged in operable combination with the housing and includes a movable first member and a movable second member carried by the first member. A portion of the second member extends beyond the housing and defines a friction surface for the cap. A spring resiliently urges the friction surface of the cap into frictional contact with railcar body structure. The cap members define cooperating angled surfaces therebetween for urging wall structure on the first member and wall structure on the second member into frictional engagement with the wall structure on said housing in response to a vertical load acting on the friction contacting surface on the cap.
