Title (EN) ELECTRONICALLY CONTROLLED ASSISTED ELECTROHYDRAULIC STEERING SYSTEM FOR COMMERCIAL VEHICLES, PUMP AND STEERING GEAR HOUSING FOR SUCH A SYSTEM
(FR) SYSTEME DE DIRECTION ELECTROHYDRAULIQUE ASSISTEE PILOTEE ELECTRONIQUEMENT POUR VEHICULES UTILITAIRES, POMPE ET BOITIER DE DIRECTION POUR UN TEL SYSTEME
Abstract:
(EN) The invention relates to an electronically controlled assisted electrohydraulic steering system for vehicles, comprising a steering column (2) provided with a torque sensor (4) located upstream of a steering gear housing (1), said steering gear housing (1) containing an endless screw (25) controlling the rotation of a shaft (22) with a toothed sector, controlling the angular displacement of a steering rod (23), the system further comprising a pump (7) driven by an electric motor (6) controlling the circulation of a fluid in the steering gear housing (1), further comprising a computer (5) comprising an input for the signals supplied by said torque sensor (4) and/or the signals supplied by an autonomous driving system (13) and controlling the throughput, the direction of rotation and the instantaneous volume of said electric pump (7), the hydraulic circuit thus formed operating as a closed circuit.
(FR) L'invention présente un système de direction électrohydraulique assistée pilotée électroniquement pour véhicules comportant une colonne de direction (2) munie d'un capteur de couple (4) situé en amont d'un boîtier de direction (1), ledit boîtier de direction (1) contenant une vis sans fin (25) commandant en rotation un arbre à secteur denté (22) pilotant le déplacement angulaire d'une bielle de direction (23), le système comportant en outre une pompe (7) entraînée par un moteur électrique (6) commandant la circulation d'un fluide dans le boîtier de direction (1) présentant en outre un calculateur (5) comportant une entrée pour les signaux délivrés par ledit capteur de couple (4) et/ou les signaux délivrés par un système de conduite autonome (13) et commandant le débit, le sens de rotation et le volume instantané de ladite pompe électrique (7), le circuit hydraulique ainsi formé fonctionnant en circuit fermé.
