Abstract

Dans un véhicule ferroviaire, les équipements électriques sont disposés sur un châssis constituant un plancher de partie basse de la coque. La construction du châssis lui-même est simplifiée de même que celle de la zone ou sont placés ces équipements électriques, et l'efficacité de fonctionnement du véhicule est accrue. Le châssis est suffisamment résistant lorsqu'il est en position de montage des bogies, pour qu'on y monte les équipements électriques. De plus, le châssis est construit de façon qu'une cabine d'équipements soit scindée en une partie ouverte et une partie fermée et que, dans cette dernière, les divers équipements qui ont des fonctions différentes ne soient pas enfermés dans une console pour équipements mais soient simplement disposés de manière à pouvoir dissiper leur chaleur. De plus, lors du montage des équipements électriques sur le châssis, celui-ci est retourné et ces équipements sont placés dans la cabine d'équipements par l'intermédiaire d'une ouverture ménagée dans la surface inférieure du châssis et fixés sur place. On peut ainsi construire un véhicule ferroviaire en raccordant le châssis, sur lequel sont montés les équipements électriques, avec dux ensembles latéraux, un ensemble toit et deux ensembles d'extrémités.
