Abstract

Suspension pneumatique caractérisée en ce qu'au moins un premier coin (8b) de la caisse (8) du véhicule peut être abaissé à un niveau de génuflexion, prédéterminé, associé à ce coin de la caisse du véhicule, ce niveau étant détecté par un capteur de course (26), l'abaissement se faisant par l'évacuation de l'air du premier soufflet (21) portant ce coin de caisse, le niveau de génuflexion étant plus haut que le niveau le plus bas du coin de caisse (8b) défini par une butée mécanique (36b).Air suspension characterized in that at least a first corner (8b) of the vehicle body (8) can be lowered to a predetermined level of genuflection associated with this corner of the vehicle body, this level being detected by a stroke sensor (26), the lowering being effected by the evacuation of the air from the first bellows (21) carrying this body corner, the level of genuflection being higher than the lowest level of the body corner ( 8b) defined by a mechanical stop (36b).
