Abstract

A friction shoe is provided for use in a railway freight car truck. A freight car truck comprises two laterally spaced sideframes with a bolster extending transversely between said sideframes. The bolster has two ends each of which extends into an opening in each sideframe and is supported by a spring group in each sideframe opening. A friction shoe is provided in a sloped pocket between each bolster end and a vertical face of the sideframe. The friction shoes are themselves comprised of a sloped wall, a vertical rear wall extending from a lower part of the rear wall to a lower part of the sloped wall, and side wall. The friction shoe provides damping for the bolster supported on each spring group. The friction shoe of the present invention is also comprised of a cast steel.
