The present invention relates to a vehicle, in particular a rail vehicle, comprising a car body (102), a first chassis (104), and a se- cond chassis (114) arranged at a distance to the first chassis (104) in the direction of a vehicle longitudinal axis, wherein the car body (102) is sup- ported on the first chassis (104) in the direction of a vehicle vertical axis by means of a first spring device (103), the car body (102) is supported on the second chassis (114) in the direction of the vehicle vertical axis by means of a second spring device (113), the car body (102) is coupled to the first chassis (104) by means of a first roll compensation device (105), the car body (102) is coupled to the second chassis (114) by means of a se- cond roll compensation device (115), the first roll compensation device (105) and the second roll compensation device (115) counteract roll moti-ons of the car body (102) toward the outside of the curve about a roll axis parallel to the vehicle longitudinal axis during curved travel, wherein the first roll compensation device (105) is designed in such a way and/or the first roll compensation device (105) and the second roll compensation de-vice (115) are coupled to each other in such a way that a torsional load on the car body (102) about the vehicle longitudinal axis, which is caused in particular by a wind load acting on the car body (102), is counteracted.

L'invention concerne un véhicule, notamment un véhicule sur rails, comportant une caisse (102), un premier châssis (104) et un deuxième châssis (114) disposé à distance du premier (104) dans la direction de l'axe longitudinal du véhicule, la caisse (102) s'appuyant sur le premier châssis (104) au moyen d'un premier dispositif ressort (103) dans la direction d'un axe vertical du véhicule, et sur le deuxième châssis (114) au moyen d'un deuxième dispositif ressort (113) dans la direction de l'axe vertical du véhicule. La caisse (102) est accouplée au premier châssis (104) au moyen d'un premier dispositif de compensation du roulis (105), et au deuxième châssis (114) au moyen d'un deuxième dispositif de compensation du roulis (115). En courbe, le premier et le deuxième dispositif de compensation du roulis (105, 115) agissent contre des mouvements de roulis de la caisse vers l'extérieur de la courbe, autour d'un axe de roulis parallèle à l'axe longitudinal du véhicule. Le premier dispositif de compensation du roulis (105) est conçu de telle manière et/ou le premier dispositif de compensation du roulis (105) et le deuxième dispositif de compensation du roulis (115) sont accouplés mutuellement de telle manière qu'une contrainte de torsion sur la caisse (102) autour de l'axe longitudinal du véhicule, notamment due à des contraintes du vent agissant sur la caisse (102), est compensée.
