Abstract

ABRÉGÉ : Il est décrit une suspension qui comprend au moins une soupape de régulation de niveau qui, lorsquelle entre en prise, permet à un débit dair de mettre en prise une soupape de commande hydraulique de manière à entraîner lextension ou la rétraction dun piston hydraulique à partir dun cylindre. Lextension ou la rétraction du piston hydraulique entraîne un cadre dappoint vers le bas ou vers le haut, respectivement. La soupape de régulation de niveau entre en prise lorsquun essieu dappoint se trouve à une distance prédéterminée du cadre. 20676251v1 CA 3066770 2020-01-07
