Abstract

L'invention concerne un dispositif d'appui du plancher d'un véhicule ferroviaire, comportant un rail de plancher (1) étendu en longueur, divisé en plusieurs tronçons longitudinaux (2, 3) en formant au moins un point de séparation, constitué d'un premier matériau métallique, et prenant appui sur la caisse du véhicule ferroviaire qui est constituée d'un deuxième matériau métallique. Dans la zone du point de séparation, le rail de plancher (1) est raccordé à un profilé intermédiaire (6) qui assure un assemblage résistant à la flexion des tronçons longitudinaux (2, 3) raccordés les uns aux autres du rail de plancher (1), un siège coulissant étant réalisé entre les tronçons longitudinaux (2, 3) du rail de plancher (1) et le profilé intermédiaire (6).
