A friction shoe for a railway car truck is provided. The railway truck comprises two parallel side frames, a suspension spring assembly supported by the side frames, and a bolster transversely mounted between the side frames and supported by the suspension spring assembly. Each side frame has at least one vertical support face, and the bolster has at least one sloped support face. The friction shoe comprises a bottom base engaging and supported by a support spring, and a sloped wall engaging the sloped support face of the bolster. The present invention includes geometric improvements in friction shoe design which prevent bolster side wall wear and helps eliminate the possibility of the friction shoe's wear on the bolster side wall from interfering with its normal movement over its service life.

    Linvention concerne un sabot de friction pour wagon. Le wagon comprend de cadres latéraux parallèles, un bloc-ressorts de suspension soutenu par les cadres latéraux et une traverse installée perpendiculairement entre les cadres latéraux et soutenue par le bloc-ressorts de suspension. Chaque cadre latéral dispose dau moins une paroi de support verticale, et la traverse présente au moins une paroi de support en pente. Le sabot de friction comprend une base montée connectée à un ressort de suspension, qui la supporte, et une paroi en pente qui se joint à la paroi de support en pente de la traverse. La présente invention comprend des améliorations géométriques dans la conception du sabot de friction qui prévient lusure de la paroi latérale de la traverse et aide à éliminer la possibilité que lusure de la traverse nuise au fonctionnement normal du sabot pendant sa durée de vie utile.
