Title
(EN) RAIL CAR SIDE BEARING
(FR) PALIER LATÉRAL DE VÉHICULE FERROVIAIRE
Abstract
(EN)
In one aspect of the present disclosure, a side bearing is provided for supporting a body of a rail car. The side bearing includes a base for being mounted to a truck of the rail car, a support configured to contact the body of the rail car and move along a vertical axis relative to the base with movement of the body, and at least one resilient foam member configured to deform with movement of the support. The side bearing further includes at least one friction damping member configured to be urged in a direction transverse to the vertical axis against the base by the support and resist movement of the support relative to the base.
(FR)
Un aspect de la présente invention concerne un palier latéral pour supporter un corps d'un véhicule ferroviaire. Le palier latéral comprend une base destinée à être montée sur un bogie du véhicule ferroviaire, un support configuré pour venir en contact avec le corps du véhicule ferroviaire et se déplacer le long d'un axe vertical par rapport à la base avec un mouvement du corps, et au moins un élément en mousse élastique configuré pour se déformer avec un mouvement du support. Le palier latéral comprend en outre au moins un élément d'amortissement à friction configuré pour être poussé dans une direction transversale à l'axe vertical contre la base par le support, et à résister à un mouvement du support par rapport à la base.
