Abstract

A.SERVO-MECANISME HYDRAULIQUE AMPLIFICATEUR DE COUPLE, COMPRENANT UN MOTEUR HYDRAULIQUE ROTATIF AGISSANT SUR UN ARBRE DE SORTIE ET UN DISTRIBUTEUR HYDRAULIQUE ACTIONNE PAR UN ARBRE D'ENTREE. B.SELON L'INVENTION, LE MOTEUR HYDRAULIQUE EST DU TYPE A PALETTES ET INCLUT UN ROTOR DONT LE CONTOUR EST DESSINE DE MANIERE A ASSURER LA FOURNITURE D'UN COUPLE AMPLIFIE CONSTANT POUR UN ORDRE D'ENTREE DONNE, ET LE DISTRIBUTEUR QUI EN CONTROLE LE FONCTIONNEMENT EST DU TYPE CENTRE OUVERT A GLACE. C.APPLICATION NOTAMMENT A LA REALISATION DE DIRECTIONS ASSISTEES POUR VEHICULES AUTOMOBILES.A.SERVO-HYDRAULIC TORQUE AMPLIFIER MECHANISM, INCLUDING A ROTATING HYDRAULIC MOTOR ACTING ON AN OUTPUT SHAFT AND A HYDRAULIC DISTRIBUTOR ACTUATED BY AN INPUT SHAFT. B. ACCORDING TO THE INVENTION, THE HYDRAULIC MOTOR IS OF THE VANE TYPE AND INCLUDES A ROTOR WHOSE CONTOUR IS DESIGNED TO ENSURE THE SUPPLY OF A CONSTANT AMPLIFIED TORQUE FOR A GIVEN INPUT ORDER, AND THE DISTRIBUTOR WHO CONTROLS IT THE OPERATION IS OF THE OPEN CENTER WITH ICE CREAM. C. APPLICATION IN PARTICULAR TO THE REALIZATION OF ASSISTED STEERING FOR MOTOR VEHICLES.
