A compensation for wheel wear of a railway truck (10) to maintain a constant car floor height above a railroad track is provided by using shims (42). The shims (42), when are not in use, are attached to a suitable location on the railway truck. A method of compensation for wheel wear comprises generally the steps of providing a wheel wear compensating shim (42) that, when not being used, is removably attached to the underside (44) of the bearing housing (34) or another suitable location of the railway truck (10), lifting of the side frame (22) of the railway truck (10) away from the primary suspension (32), disposing the compensating shim (42) between the side frame (22) and the primary suspension (32), and finally lowering the side frame (22) back onto the shim (42) and primary suspension (32). The railway truck (10) can thus be shimmed for wheel wear at any location where the side frame (22) and accompany car body can be lifted without the need to take the railcar to a retrofit service shop.
La présente invention concerne l'utilisation de cales (42) pour compenser l'usure du bogie (10) de façon à conserver constante la hauteur du plancher de wagon au-dessus de la voie. Les cales (42), lorsqu'elles ne sont pas utilisées, sont fixées en un endroit approprié du bogie. En l'occurrence, on commence par réaliser une cale de correction d'usure de bandage (42) qui, hors utilisation, est fixée contre la face inférieure (44) de la boîte de roulement (34) ou en tout autre endroit approprié du bogie (10). Le procédé consiste alors à soulever de la suspension primaire (32) le longeron latéral (22) du bogie (10), à intercaler la cale de compensation (42) entre le longeron latéral (22) et la suspension primaire (32), puis à reposer le longeron latéral (22) sur la cale (42) et la suspension primaire (32). L'invention permet ainsi de reprendre l'effet de l'usure des bandages du bogie (10) en n'importe quel endroit où il est possible de soulever le longeron latéral du bogie (22) en même temps que son wagon, sans pour autant être obligé d'amener le wagon en atelier de grande maintenance.
