Title (DE) BREMSANLAGE FÜR EIN KRAFTFAHRZEUG
(EN) BRAKING SYSTEM FOR A MOTOR VEHICLE
(FR) SYSTEME DE FREINAGE POUR VEHICULE AUTOMOBILE
Abstract:
(DE) Die Erfindung betrifft eine Bremsanlage (10) für ein Kraftfahrzeug mit einem Hydraulikkreis (12) zur Erzeugung einer Bremskraft, wobei der Hydraulikkreis (12) eine Druckquelle (50) zur Erzeugung eines Hydraulikdrucks und einen Druckspeicher (58) aufweist, wobei der Druckspeicher (58) des Hydraulikkreises (12) bedarfsweise mit Hydraulikfluid von einer Druckseite der Druckquelle (50) beschickbar ist. Bei dieser Bremsanlage ist vorgesehen, dass der Druckspeicher (58) mit einer Saugseite der Druckquelle (50) über ein zwischengeschaltetes aktiv ansteuerbares Mehrwegeventil (64), insbesondere ein Zwei-Wege-Magnetventil, fluidisch koppelbar sowie von diesem entkoppelbar ist.
(EN) The invention relates to a braking system (10) for a motor vehicle having a hydraulic circuit (12) for generating a braking force, the hydraulic circuit (12) having a pressure source (50), for generating a hydraulic pressure, and a pressure accumulator (58), it being possible for the pressure accumulator (58) of the hydraulic circuit (12) to be supplied on demand with hydraulic fluid from a pressure side of the pressure source (50). In said braking system, it is provided that the pressure accumulator (58) can be fluidically coupled to, and decoupled from, a suction side of the pressure source (50) by means of a multiple-way valve (64), in particular a two-way valve, which is connected in between and can be actively actuated.
(FR) La présente invention concerne un système de freinage (10) destiné à un véhicule automobile, comprenant un circuit hydraulique (12) qui sert à produire une force de freinage, le circuit hydraulique (12) présentant une source de pression (50) qui sert à produire une pression hydraulique, et un accumulateur de pression (58) qui peut au besoin être alimenté en liquide hydraulique par un côté pression de la source de pression (50). Dans ce système de freinage, l'accumulateur de pression (58) peut être couplé et découple d'un point de vue fluidique, au côté aspiration de la source de pression (50), par une soupape à plusieurs voies (64), en particulier une soupape à deux voies, qui est intercalée entre les deux et peut être commandée de façon active.
