Abstract

A.DISPOSITIF POUR VEHICULE AVEC VOLANT ET COLONNE DE DIRECTION, ET DIRECTION ASSISTEE COMPRENANT UNE POMPE HYDRAULIQUE ET EVENTUELLEMENT, UNE SOUPAPE COMMANDEE PAR LE VOLANT, POMPE ENTRAINEE PAR UN MOTEUR AUXILIAIRE MIS EN CIRCUIT PAR UN DISPOSITIF DE MESURE DE LA FORCE APPLIQUEE SUR LA COLONNE DE DIRECTION. B.CARACTERISE EN CE QU'IL EST PREVU, POUR LA MESURE DE LA FORCE QUI S'APPLIQUE A LA COLONNE DE DIRECTION 11, UN ORGANE 12 DE MESURE DU COUPLE QUI EMET UN SIGNAL DE TENSION ELECTRIQUE; CET ORGANE DE MESURE DU COUPLE 12 ETANT RELIE A UN TRANSDUCTEUR TENSION-IMPULSION AUQUEL EST RELIE UN APPAREIL 24 QUI FOURNIT AU MOTEUR ELECTRIQUE AUXILIAIRE 21 UNE TENSION DONT LA VALEUR MOYENNE EST PROPORTIONNELLE AU COUPLE APPLIQUE A LA COLONNE DE DIRECTION. C.DISPOSITIF APPLICABLE A DES VEHICULES TELS QUE CHARIOTS ELEVATEURS.A. DEVICE FOR VEHICLES WITH STEERING WHEEL AND STEERING COLUMN, AND ASSISTED STEERING INCLUDING A HYDRAULIC PUMP AND POSSIBLY, A VALVE CONTROLLED BY THE STEERING WHEEL, PUMP DRIVEN BY AN AUXILIARY MOTOR CIRCUITED BY A DEVICE FOR MEASURING THE FORCE APPLIED OF MANAGEMENT. B. CHARACTERIZED IN THAT IT IS PROVIDED FOR THE MEASUREMENT OF THE FORCE APPLIED TO THE STEERING COLUMN 11, A TORQUE MEASURING UNIT 12 WHICH EMITS AN ELECTRIC TENSION SIGNAL; THIS TORQUE MEASURING BODY 12 BEING CONNECTED TO A VOLTAGE-PULSE TRANSDUCER TO WHICH IS CONNECTED AN APPARATUS 24 WHICH PROVIDES THE AUXILIARY ELECTRIC MOTOR 21 A VOLTAGE WHOSE AVERAGE VALUE IS PROPORTIONAL TO THE TORQUE APPLIED TO THE STEERING COLUMN. C. DEVICE APPLICABLE TO VEHICLES SUCH AS FORKLIFTS.
