Title (EN) INTEGRATED MASTER-CYLINDER FOR BRAKE-BY-WIRE BRAKING SYSTEM AND BRAKE-BY-WIRE BRAKING SYSTEM WEITH THE SAME
(FR) MAÎTRE-CYLINDRE INTÉGRÉ POUR SYSTÈME DE FREINAGE PAR CÂBLE ET SYSTÈME DE FREINAGE PAR CÂBLE LE COMPRENANT
Abstract:
(EN) A brake pump (8) for the braking system of vehicles (4) having a pump body (16) comprising: a first and a second delivery circuit (20,24) fluidically connectable to at least a first and a second braking device (28,32), - wherein the first delivery circuit (20) comprises an indirect stage (36) fluidically connectable to the first braking device (28) and a direct stage (40) intercepted by a first control valve (44), fluidically connectable alternately to a braking simulator (48) and to said at least one second braking device (32) so as to alternately connect the direct stage (40) to the braking simulator (48) or to said at least one second braking device (32) for the actuation thereof, - wherein the second delivery circuit (24) is intercepted by said first control valve (44) so as to actuate the second braking device (32) alternately to the direct stage of the first delivery circuit (20). The pump body (16) has an input connection (56) to an actuating hydraulic circuit (60), traversed by an actuating fluid different from the said brake fluid and fluidically separated therefrom, and houses a first and a second float (72,76), fluidically connected respectively in output to the direct (40) and indirect (36) stages of the first delivery circuit (20). Moreover, the pump body (16) houses a third float (96) operatively connected, in input, to the input connection (56) of the hydraulic actuation circuit (60) and, in output, to the second delivery circuit (24).
(FR) Pompe de frein (8) pour le système de freinage de véhicules (4) ayant un corps de pompe (16) comprenant : un premier et un second circuit de distribution (20, 24) pouvant être reliés fluidiquement à au moins un premier et un second dispositif de freinage (28, 32), le premier circuit de distribution (20) comprenant un étage indirect (36) pouvant être relié fluidiquement au premier dispositif de freinage (28) et un étage direct (40) intercepté par une première soupape de commande (44), pouvant être relié fluidiquement en alternance à un simulateur de freinage (48) et au dit au moins un second dispositif de freinage (32) de manière à relier alternativement l'étage direct (40) au simulateur de freinage (48) ou au dit au moins un second dispositif de freinage (32) pour l'actionnement de celui-ci, le second circuit de distribution (24) étant intercepté par ladite première soupape de commande (44) de manière à actionner le second dispositif de freinage (32) en alternance à l'étage direct du premier circuit de distribution (20). Le corps de pompe (16) présente une liaison d'entrée (56) à un circuit hydraulique d'actionnement (60), traversé par un fluide d'actionnement différent dudit fluide de frein et séparé fluidiquement de celui-ci, et loge un premier et un deuxième flotteur (72, 76), reliés fluidiquement respectivement en sortie aux étages direct (40) et indirect (36) du premier circuit de distribution (20). De plus, le corps de pompe (16) loge un troisième flotteur (96) fonctionnellement relié, en entrée, à la connexion d'entrée (56) du circuit d'actionnement hydraulique (60) et, en sortie, au second circuit de distribution (24).
