Abstract
Description
Die Erfindung betrifft eine Bremsanlage mit einer Einrichtung zur Regelung des Brems- und Antriebsschlupfes und/oder zur Fahrdynamikregelung in einem Kraftfahrzeug nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a brake system with a device for controlling the brake and drive slip and / or for driving dynamics control in a motor vehicle according to Preamble of claim 1.
Aus der
Die Realisierung der Bremsanlage erfordert schaltungstechnisch als auch konstruktiv einen erheblichen Aufwand.Realization of the brake system requires a considerable amount in terms of circuitry and design Expenditure.
Es ist daher eine Aufgabe der vorliegenden Erfindung, eine Bremsanlage der angegebenen Art derart zu verbessern, dass der konstruktive und schaltungstechnische Realisierungsaufwand verringert wird.It is therefore an object of the present invention to improve a brake system of the type specified in such a way that the constructive and circuitry-related implementation effort is reduced becomes.
Die Aufgabe wird erfindungsgemäß gelöst, indem die Radbremsen oder die Druckkammern an einen Ausgang oder an einen Eingang einer einzigen Fördervorrichtung angeschlossen sind, und daß für den Anschluß wenigstens ein Druckmittelkanal vorgesehen ist, welcher Mittel zum Auftrennen oder zum Bündeln des geförderten Druckmittels aufweist. Die Erfindung ermöglicht eine überraschend einfache Konstruktion mit entsprechend reduzierten Herstellkosten.The object is achieved by the wheel brakes or the pressure chambers to an outlet or to one Entry of a single conveyor are connected, and that for the connection at least a pressure medium channel is provided, which means for the separation or to bundle of the funded Has pressure medium. The invention enables a surprising simple construction with correspondingly reduced manufacturing costs.
In weiterer Ausgestaltung der Erfindung ist für die Bremskreise eine gemeinsame Saugleitung und eine gemeinsame Druckleitung vorgesehen, welche jeweils einen hydraulischen Abzweig zur Auffächerung aufweisen. Jeder der Abzweige ist bezüglich der Fördervorrichtung stromauf beziehungsweise stromab angeordnet, so daß sich der Aufwand zur Verbohrung eines Aufnahmekörpers für die Fördervorrichtung infolge einer verringerten Bohrungszahl reduziert. Erfindungsgemäß wird auch der Bauraumbedarf gesenkt.In a further embodiment of the invention is for the brake circuits have a common suction line and a common one Pressure line provided, which each have a hydraulic branch for fanning out exhibit. Each of the branches is upstream or downstream with respect to the conveying device arranged so that the effort to drill a receiving body for the conveyor as a result of reduced number of holes reduced. According to the invention the space requirement is reduced.
Bei einer Ausgestaltung der Erfindung ist der Abzweig T-förmig ausgebildet. Jeder Abzweig kann eine zufließende Leitungen und zwei abfließende Leitungen (stromabwärts, Druckseite) oder aber in umgekehrter Weise zwei zufließende Leitungen und eine abfließende Leitung (stromaufwärts, Saugseite) aufweisen.In one embodiment of the invention the branch is T-shaped. Each branch can be an incoming Lines and two draining lines (downstream, pressure side) or, conversely, two incoming lines and one outgoing line (Upstream, Suction side).
Auf den stromabwärts vorgesehenen Abzweig folgen zwei Versorgungsleitungen, in die jeweils ein Rückschlagventil integriert ist, um einen der Bremskreise beispielsweise bei einer Fehlfunktion in dem anderen Bremskreis weiter betreiben zu können. Zur Trennung der Bremskreise im Saugtrakt ist stromaufwärts nach dem Abzweig in jede Saugleitung ein Rückschlagventil integriert.Follow the branch to the downstream two supply lines, in each of which a check valve is integrated, around one of the brake circuits, for example in the event of a malfunction in the to be able to continue operating another brake circuit. To separate the brake circuits in the suction tract is upstream A check valve is integrated into each suction line after the branch.
Zur Reduktion der Baugröße des Aufnahmekörpers ist die Fördervorrichtung als Zahnradpumpe ausgebildet, in deren Ansaugtrakt die gemeinsame Saugleitung einmündet, und in deren Druckerhöhungstrakt die gemeinsame Druckleitung einmündet.To reduce the size of the receiving body the conveyor formed as a gear pump, in the intake tract of the common suction line opens, and in their pressure increase tract the common pressure line opens.
