Furthermore, the torsion-beam axle consists of a twistable tubular part connecting the two trailing arms. The trailing arms are each extended beyond the pipe part and take at their ends guide axes of rotation, over which the torsion beam axle is pivotally guided at the bottom of the structure. A cross-sheet suspension device is connected at each of its two ends via a coupling device with each of the two trailing arms.

Abstract

Ensemble ressort à lames pour trains roulants d'un véhicule, présentant un ressort à lames transversal (6) qui peut être agencé transversalement à l'axe longitudinal du véhicule et dont les extrémités peuvent être accouplées à des porte-moyeux (4 et 5), un logement pour un dispositif de type parallélogramme de Watt (19) ou un dispositif de type barre Panhard étant situé sur une traverse (10) de type poutre, pouvant être reliée à un fond d'une caisse du véhicule. L'objectif de l'invention est de réduire le nombre des pièces nécessaires et les dimensions de construction dudit ensemble dans une suspension comportant un ressort se présentant sous la forme d'un ressort à lames transversal et un dispositif de guidage de la caisse. A cet effet, le ressort à lames transversal (6) est agencé sur la traverse (10).
