Abstract

L’invention se rapporte à un véhicule comprenant un châssis (2) à position verticale commandée, comprenant une pluralité de roues, et, associés à chaque roue : - un bras de suspension (28) portant la roue, le bras étant monté pivotant sur le châssis (2) ; - un actionneur (32) de bras de suspension, agencé entre le bras de suspension (28) et le châssis (2), l’actionneur permettant de commander une position angulaire du bras relativement au châssis, afin de faire varier la position verticale de ce châssis. Selon l’invention, le véhicule comprend de plus, associé à chaque roue, un dispositif de blocage en rotation de son bras de suspension (28), le dispositif de blocage étant configuré pour empêcher la rotation du bras par rapport au châssis dans les deux sens de rotation, lorsque le châssis se trouve en position basse d’appui sur le sol. Figure pour l’abrégé : Figure 6The invention relates to a vehicle comprising a chassis (2) with a controlled vertical position, comprising a plurality of wheels, and, associated with each wheel: - a suspension arm (28) carrying the wheel, the arm being pivotally mounted on the frame (2); - a suspension arm actuator (32), arranged between the suspension arm (28) and the chassis (2), the actuator making it possible to control an angular position of the arm relative to the chassis, in order to vary the vertical position of this chassis. According to the invention, the vehicle further comprises, associated with each wheel, a device for locking its suspension arm (28) in rotation, the locking device being configured to prevent rotation of the arm relative to the chassis in both direction of rotation, when the chassis is in the low support position on the ground.
