Abstract

L’invention propose un dispositif antiroulis (30) pour véhicule automobile. Un vérin hydraulique (32) comprend : une tige d’actionnement (36), une première chambre (40), une deuxième chambre (42), une troisième chambre (44). Le circuit hydraulique (34) comprend : un accumulateur hydraulique (46) avec du liquide hydraulique, une première branche (48) entre la première chambre et l’accumulateur hydraulique, une deuxième branche (50) entre la deuxième chambre et l’accumulateur hydraulique, deux vannes (52), deux clapets anti-retour apte à bloquer un flux de liquide hydraulique de l’accumulateur hydraulique vers le cylindre. Le vérin hydraulique comprend un premier piston (56) mobile par rapport à la tige d’actionnement et délimitant la première chambre, un deuxième piston (58) mobile par rapport à la tige d’actionnement et délimitant la deuxième chambre, des moyens d’entraînement (60) de la tige d’actionnement par le premier piston vers la deuxième chambre, et par le deuxième piston vers la première chambre. Figure à publier avec l’abrégé : Figure 2The invention proposes an anti-roll device (30) for a motor vehicle. A hydraulic cylinder (32) comprises: an actuating rod (36), a first chamber (40), a second chamber (42), a third chamber (44). The hydraulic circuit (34) comprises: a hydraulic accumulator (46) with hydraulic fluid, a first branch (48) between the first chamber and the hydraulic accumulator, a second branch (50) between the second chamber and the hydraulic accumulator, two valves (52), two non-return valves capable of blocking a flow of hydraulic fluid from the hydraulic accumulator to the cylinder. The hydraulic cylinder comprises a first piston (56) movable relative to the actuating rod and delimiting the first chamber, a second piston (58) movable relative to the actuating rod and delimiting the second chamber, means (60) for driving the actuating rod by the first piston towards the second chamber, and by the second piston towards the first chamber.
