(DE) BREMSSYSTEM MIT DRUCKMODULATIONSZYLINDER
(EN) BRAKE SYSTEM HAVING A PRESSURE MODULATION CYLINDER

Abstract
(DE)
Die Erfindung betrifft eine Bremsvorrichtung für Kraftfahrzeuge mit einem Hauptbremszylinder (2) zum Erzeugen von Bremsdruck an wenigstens einer Radbremse (15a-15d). Um den Bremsdruck an einzelnen Radbremsen (15a-15d) individuell verändern zu können, ist zwischen dem Hauptbremszylinder (2) und den Radbremsen (15a-15d) ein Druckmodulationszylinder (7) vorgesehen, der mehrere Kammern (17, 18) aufweist, wobei eine erste Kammer (17) über eine erste Fluidleitung (19) mit dem Hauptbremszylinder (2), und eine zweite Kammer (17) über eine zweite Fluidleitung (20) mit der wenigstens einer Radbremse (15a- 15d) verbunden ist. Die erste und zweite Kammer (17), (18) sind über eine Fluidleitung, in der ein Ventil (12) angeordnet ist, miteinander verbunden. Ein solches Bremssystem ist besonders einfach aufgebaut und daher kostengünstig zu realisieren.
(EN)
The invention relates to a brake device for motor vehicles, having a main brake cylinder (2) for generating brake pressure on at least one wheel brake (15a-15d). In order to be able to individually change the brake pressure on individual wheel brakes (15a-15d), a pressure modulation cylinder (7) is provided between the main brake cylinder (2) and the wheel brakes (15a-15d), said cylinder having a plurality of chambers (17, 18), wherein a first chamber (17) is connected via a first fluid line (19) to the main brake cylinder (2), and a second chamber (17) is connected via a second fluid line (20) to the at least one wheel brake (15a-15d). The first and second chambers (17), (18) are connected to each other via a fluid line, in which a valve (12) is arranged. Such a brake system has a particularly simple design and can thus be produced in a cost-effective manner.

L'invention concerne un dispositif de freinage pour véhicules automobiles comprenant un maître-cylindre de frein (2) pour générer de la pression de freinage sur au moins un frein de roue (15a-15b). Afin de pouvoir modifier individuellement la pression de freinage sur des freins de roue individuels (15a-15b), il est prévu entre le maître-cylindre de frein (2) et les freins de roue (15a-15d) un cylindre à modulation de pression (7), qui présente plusieurs chambres (17, 18), une première chambre (17) étant reliée par une première conduite de fluide (19) au maître-cylindre de frein (2), et une seconde chambre (17) étant reliée par une seconde conduite de fluide (20) au au moins un frein de roue (15a-15d). La première et la seconde chambre (17, 18) sont reliées l'une à l'autre par une conduite de fluide, dans laquelle est disposée une soupape (12). Un tel système de freinage est conçu de façon particulièrement simple et est donc avantageux à réaliser.
