Abstract

Un essieu de levage de suspension pour une remorque tandem comprend un premier et un deuxième coussin dair de suspension pour un premier et un deuxième essieu. Il y a un coussin dair de levage qui, lorsque pressurisé, applique une force de levage pour lever le deuxième essieu par rapport au premier. Un premier circuit pneumatique fournit de lair comprimé au premier coussin dair de suspension et à une valve de dérivation et est contrôlé par un robinet sélecteur de hauteur ouvert et fermé en fonction de lassiette de la remorque. La valve de dérivation distribue sélectivement lair comprimé au deuxième coussin dair de suspension et à régulateur de pression qui limite la pression dair à une pression prédéterminée. Un deuxième circuit pneumatique distribue de lair comprimé au coussin dair de levage et est contrôlé par une vanne pilote.
