ABSTRACT:
A friction wedge for use in damping relative movement between the bolster and the side frame of a railroad car truck includes a body formed and adapted to be positioned in a pocket of one of the bolster and side frame. The body has spaced body portions integrally joined by an intermediate connecting portion. Each of the spaced body portions has a friction surface formed and adapted during normal use to be in frictional contact with a wear resistant surface on the other of the bolster and side frame. The spaced friction surfaces on the wedge body are effective to increase the resistance to bolster/side frame warp movement over and above the resistance provided by a continuous friction surface which is equal in width to the distance between the outside of each of the spaced friction surfaces.
