Title (DE) BREMSANLAGE
(EN) BRAKE SYSTEM
(FR) SYSTEME DE FREINAGE
Abstract:
(DE) Eine Bremsanlage (10) mit einem Hauptbremszylinder (12), der wenigstens eine Zylinder/Kolbenanordnung (14, 16) aufweist, die durch ein Bremspedal (18) betätigbar ist, um wenigstens einem Bremskreis (22, 24) Hydraulikfluid zuzuführen, ist gekennzeichnet durch eine steuerbare Druckquelle (54, 78, 90, 92), die gesteuert von einer elektronischen Steuereinheit ECU den Kolben (16) der Zylinder/Kolbenanordnung (14, 16) im Sinne einer Zufuhr von Hydraulikfluid zu dem Bremskreis (22, 24) mit Hydraulikfluid beaufschlagt.
(EN) The invention relates to a brake system (10) with a master cylinder (12) having at least one cylinder/piston arrangement (14, 16) which can be operated by a brake pedal (18) to supply hydraulic fluid to at least one braking circuit (22, 24). Said brake system is characterized by the fact that a controllable pressure source (54, 78, 90, 92) controlled by an electronic ECU control unit loads the piston (16) of the cylinder/piston arrangement (14, 16) with hydraulic fluid so as to supply hydraulic fluid to the brake circuit (22, 24).
(FR) L'invention concerne un système de freinage (10) comprenant un maître-cylindre (12) comportant au moins un système cylindre/piston (14, 16) qui peut être actionné par une pédale de frein (18) pour alimenter un circuit de freinage (22, 24) en fluide hydraulique. Ce système de freinage (10) se caractérise en ce qu'une source de pression (54, 78, 90, 92) commandée par une unité électronique ECU, applique du fluide hydraulique sur le piston (16) du système cylindre-piston (14, 16), afin d'acheminer ledit fluide hydraulique jusqu'au circuit de freinage (22, 24).
