Abstract

Une traverse danseuse (11) selon la présente invention élastiquement supportée par une suspension pneumatique disposée sur la surface supérieure d'un châssis de bogie est formée d'une traverse danseuse centrale (20) située de manière centrale dans la direction de la largeur et de traverses danseuses d'extrémité (21) disposées des deux côtés de celui-ci. Ces traverses danseuses (20, 21) sont des éléments extrudés comprenant une plaque de surface supérieure, une plaque de surface inférieure et de multiples nervures raccordant ces éléments les uns aux autres. Étant donné qu'une plaque de surface supérieure (23a) et une plaque de surface inférieure (23b) formant la traverse danseuse centrale (20) sont disposées à un niveau supérieur à celui d'une plaque de surface supérieure (21a) et d'une plaque de surface inférieure (21b) formant les traverses danseuses d'extrémité (21), il devient possible de former un espace dans la direction de la hauteur d'une carrosserie de véhicule entre la surface inférieure de la traverse danseuse centrale (20) et la surface supérieure du châssis de bogie et de disposer un bogie sans traverse au-dessous de la traverse danseuse (11).
