Abstract

INVENTION CONCERNANT LE FREINAGE DES VEHICULES. ENSEMBLE D'ACTUATEUR HYDRAULIQUE POUR SYSTEME DE FREINAGE DE VEHICULE, COMPRENANT UN ENSEMBLE DE MAITRE-CYLINDRE HYDRAULIQUE 4 ACTIONNE PAR UN RENFORCATEUR 5 A PEDALE ET INCLUANT UN PISTON 19 SE DEPLACANT DANS UN ALESAGE 3 POUR METTRE LE FLUIDE SOUS PRESSION DANS UN PREMIER VOLUME 21. UN ENSEMBLE 11 DE VALVE DE COMMANDE POUVANT ETRE ACTIONNE EN REPONSE A DU FLUIDE SOUS PRESSION DANS LE VOLUME 21 REGLE LA COMMUNICATION ENTRE UNE ENTREE 12 RELIEE A UNE SOURCE 13 DE FLUIDE HYDRAULIQUE SOUS PRESSION ET UNE SORTIE 16. LE RENFORCATEUR 5 PEUT ETRE DU TYPE PNEUMATIQUE DIFFERENTIEL, OU DU TYPE HYDRAULIQUE AVEC UNE DEUXIEME SOURCE. LE VOLUME 21 ET LA SORTIE 16 PEUVENT ETRE RELIES A DES ACTUATEURS DE MEMES ROUES OU DE ROUES DIFFERENTES. APPLICATION A LA REALISATION DE FREINS HYDRAULIQUES DE CE GENRE.INVENTION RELATING TO THE BRAKING OF VEHICLES. HYDRAULIC ACTUATOR ASSEMBLY FOR VEHICLE BRAKING SYSTEM, INCLUDING HYDRAULIC MASTER CYLINDER ASSEMBLY 4 PEDALED BY A 5 PEDAL BOOSTER AND INCLUDING A PISTON 19 MOVING IN A BORE 3 TO PRESSURE FLUID IN A PREMIER 21 A CONTROL VALVE ASSEMBLY 11 THAT CAN BE ACTUATED IN RESPONSE TO PRESSURIZED FLUID IN VOLUME 21 REGULATES THE COMMUNICATION BETWEEN AN INPUT 12 CONNECTED TO A SOURCE 13 OF HYDRAULIC FLUID UNDER PRESSURE AND AN OUTPUT 16. THE REINFORCER 5 CAN BE FROM THE DIFFERENTIAL PNEUMATIC TYPE, OR HYDRAULIC TYPE WITH A SECOND SOURCE. VOLUME 21 AND OUTPUT 16 CAN BE CONNECTED TO ACTUATORS OF SAME WHEELS OR DIFFERENT WHEELS. APPLICATION TO THE REALIZATION OF HYDRAULIC BRAKES OF THIS KIND.
