Abstract

L'invention concerne une poutre longitudinale (1) et une traverse (18) pour un châssis de train de roulement d'un véhicule ferroviaire. La poutre longitudinale (1) comprend une première partie de jonction en forme de caisson (13) présentant un premier bord circulaire droit par endroits pour la jonction de la traverse (18), la traverse (18) comprenant à chaque extrémité dans une direction transversale du châssis de train de roulement une seconde partie de jonction en forme de caisson (24) avec un second bord circulaire droit par endroits pour la jonction de la poutre longitudinale (1). Pour obtenir une réduction du poids de la poutre longitudinale (1) et de la traverse (17) ainsi que pour diminuer la résistance au gauchissement du châssis de train de roulement, les premier et second bords circulaires sont conçus respectivement en tant que quatre premiers et seconds bords de jonction (14,15,16) qui sont séparés les uns des autres par des premier et second évidements (17).
