Abstract
A self lubricating wear plate arrangement for supporting the inner end of the vertical yoke used in coupler draft gear rigging in which the wear plate is in the form of a planar support plate equipped with a special liner for supporting the yoke inner end at its operative level within the car center sill. The liner is formed from an ultra high molecular weight polymer material that is of dry, self lubricating, nature and resists adherence thereto of foreign materials and serves as a sound deadener and energy absorber. Such material is also characterized by its polishing action on the yoke underside surface portion riding on same to re-form such yoke surface to define a mirror finish for inhibiting further wear of the yoke at this location during use.
