ABSTRACT:
The present invention provides a friction shoe for use in a railway freight car truck. The friction shoe consists of a cast metal body having a generally flat vertical surface adapted to abut a column on the truck side frame and sloped surfaces adapted to abut a corresponding sloped surface of the truck bolster. Resilient, elastomeric pads are adapted to be received on each sloped surface of the friction shoe. The sloped surface of the friction shoe has either a slot or a protrusion running lengthwise parallel to an outer edge of the sloped surface, and the elastomeric pad has either a correspoding protrusion or slot adapted to fit in the complementary sloped surface. The elastomeric pad may be wedge shaped tapering in reduced thickness from its bottom edge toward its top edge, or the pad may comprise two components each of which tapers from its top edge toward its bottom edge with a complementary adapted sloped surface on the friction shoe.
