Waggon Union Gmbh

A bearing socket for the pin connection of trucks to the body of rail vehicles comprises an upwardly opening cup-shaped lower part having a pivot pin receiving bore for the path of the pivot pin. An upwardly opening cup-shaped insert of resilient material is disposed within the lower part and has an annular side wall and a bottom wall with approximately the same thickness throughout. An upwardly opening cup-shaped upper part is disposed within the insert and both the insert and the upper part have bores for accommodating the pivot pin. The lower part advantageously has a hub portion and the insert is cut away and has a bead-shaped protuberance formed around the cut away portion surrounding the hub of the lower part. The outer walls of both the insert and the upper and lower parts are conically formed and shaped so that they interengage. The insert is prestressed and fixed between the upper and lower parts so that it absorbs the rotary motion of the bearing by elastic deformation without any sliding between the insert and the upper and lower parts.
