Abstract

La présente invention concerne un châssis de bogie, destiné à un véhicule ferroviaire, qui comprend deux longerons (1) et au moins une poutre transversale (2, 3). Selon l'invention, pour réduire le poids du châssis de bogie par rapport à des poutres creuses fermées, les longerons (1) et au moins une poutre transversale (2, 3) sont chacun formés uniquement d'un profil ouvert.
