Title (EN) BRAKE SYSTEM
(FR) SYSTÈME DE FREINAGE
(DE) BREMSSYSTEM
Abstract:
(EN) The invention relates to a brake system comprising: an actuating device, in particular a brake pedal (1); a first piston-cylinder unit (THZ) having two pistons (12,16) subjecting the brake circuits (BK1, BK2) to a pressure medium via a valve device (FV), wherein one of the pistons (16) can be actuated by the actuation device (1); a second piston-cylinder unit (DV) having an electric motor drive (8), a transmission (7) at least one piston (10) to supply at least one of the brake circuits (BK1) with a pressure medium via a valve device (PD1); and a motor pump unit (ESP) with a valve device (HSV, USV, EV, AV) to supply the brake circuits with a pressure medium, also comprising a hydraulic travel simulator (WS) with a pressure or working chamber (43) which is connected to the first piston-cylinder unit (THZ). The present application also comprises another six independent claims or inventions.
(FR) L'invention concerne un système de freinage comportant - un dispositif d'actionnement, en particulier une pédale de frein (1), - un premier ensemble cylindre-piston (THZ) comportant deux pistons (12, 16) destinés à soumettre des circuits de freinage (BK1,BK2) à un fluide sous pression via un système de soupape (FV), un des pistons (16) pouvant être actionné par le dispositif d'actionnement (1), - un second ensemble cylindre–piston (DV) comportant un entraînement à moteur électrique (8), - une transmission (7) et - au moins un piston (10) servant à alimenter au moins un des circuits de freinage (BK1) en fluide sous pression via un système de soupape (PD1), - et un ensemble moteur-pompe (ESP) muni d'un système de soupape (HSV, USV, EV, AV) et servant à alimenter les circuits de freinage en fluide sous pression. Le système de freinage est caractérisé en ce qu'un simulateur de course hydraulique (WS) comportant une chambre de pression ou de travail (43) est raccordé au premier ensemble cylindre-piston (THZ).
(DE) Die erste Erfindung betrifft ein Bremssystem mit - einer Betätigungseinrichtung, insbesondere einem Bremspedal (1), - einer ersten Kolben-Zylinder-Einheit (THZ) mit zwei Kolben (12,16) um über eine Ventileinrichtung (FV) Bremskreise (BK1,BK2) mit Druckmittel zu beaufschlagen, wobei einer der Kolben (16) mittels der Betätigungseinrichtung (1) betätigbar ist, - einer zweiten Kolben-Zylinder-Einheit (DV) mit -- einem elektromotorischen Antrieb (8), -- einem Getriebe (7) und -- zumindest einem Kolben (10), um zumindest einem der Bremskreise (BK1) über eine Ventileinrichtung (PD1) Druckmittel zuzuführen, - einer Motor-Pumpen-Einheit (ESP), mit Ventileinrichtung (HSV,USV,EV,AV), um den Bremskreisen Druckmittel zuzuführen, wobei - ein hydraulischer Wegsimulator (WS) mit einem Druck- bzw. Arbeitsraum (43) der ersten Kolben-Zylinder-Einheit (THZ) verbunden ist. Die vorliegende Anmeldung umfasst noch weitere sechs unabhängigen Ansprüche bzw. Erfindungen.
