Abstract

L'invention concerne un dispositif de traction de suspension de bogie à utiliser dans un véhicule ferroviaire articulé à plancher surbaissé, le dispositif comprenant un ensemble traverse (6), un ensemble liaison de traction (7), un ensemble suspension à un étage et un ensemble suspension à deux étages (8); l'ensemble suspension à deux étages est monté entre l'ensemble traverse et un châssis du bogie (2); deux ensembles des ensembles traverse et deux ensembles des ensembles liaison de traction sont respectivement prévus; les deux ensembles d'ensembles traverse sont disposés au milieu de deux paires de roues (4), respectivement; chaque ensemble traverse est relié au châssis au moyen d'un ensemble de l'ensemble liaison de traction (7) et chaque ensemble traverse est relié à un corps de véhicule par un mécanisme rotatif (101). Le dispositif a une structure simple et compacte et est léger; pendant le fonctionnement du véhicule, les forces de traction et de freinage peuvent être mieux transmises, les charges verticales, horizontales et longitudinales peuvent être mieux portées et la capacité de négociation de petit virage du véhicule peut être considérablement améliorée; par ailleurs, la hauteur du plancher peut être réduite, ce qui améliore notablement les performances de conduite du véhicule.
