Zweikreis-BremskraftverstärkerDual circuit brake booster

Stand der TechnikState of the art

Die Erfindung geht aus von einem Stand der Technik nach der Gattung des Hauptanspruchs. Ein derartiger Bremskraftverstärker ist bekannt (DE-OS 26 09 905). Bei einem derartigen bekannten Bremskraftverstärker wird für die beiden Kreise nur ein einziges Brems- oder Steuerventil verwendet und der vom Steuerventil in den einen Bremskreis eingesteuerte Druck ist dann auch im anderen Bremskreis wirksam. Das hat den Hachteil, daß bei Ausfall des Steuerventils beide Bremskreise ohne Ver-"***■ Stärkung auskommen müssen.The invention is based on a prior art according to the preamble of the main claim. Such a brake booster is known (DE-OS 26 09 905). In such a known brake booster is for the two Circuits only a single brake or control valve is used and that of the control valve in the one brake circuit The applied pressure is then also effective in the other brake circuit. This has the disadvantage that in the event of failure of the control valve both brake circuits without ver - "*** ■ Strengthening have to get along.

Man hat deshalb auch schon Bremskraftverstärker mit zwei Steuerventilen ausgerüstet, wobei dann jedes Steuerventil seinen eigenen Wegsimulator braucht. Die Wegsimulation ist notwendig, damit der Fahrer gefühlvoll bremsen kann und der vom Steuerventil jeweils eingesteuerte Druck das Steuerventil so gegen seine Ausgangslage zurückschiebt, daß sich die jeweilig herrschenden Kräfte auswiegen. Wenn eine solche Wegsimulation doppelt benötigt wird, entstehen .aber beachtliche Kosten.That's why you already have brake boosters with two Equipped with control valves, each control valve then needing its own travel simulator. The path simulation is necessary so that the driver can brake sensitively and that of the control valve controlled pressure pushes the control valve back against its starting position so that the respective balance ruling forces. If such a path simulation is needed twice, but there are considerable costs.

Vorteile der ErfindungAdvantages of the invention

Der Zweikreis-Bremskraftverstärker mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß er durch den geringeren Aufwand billiger, ist. Außerdem ist sein Gewicht vermindert. Desweiteren ist er wegen der geringeren Teilezahl ausfallsicherer als bekannte Bauarten. Schließlich ist er besonders geeignet für eine integrierte Bauweise, wobei die Funktion der BremskraftverStärkung und die Druckbeschaffung sowie gegebenenfalls auch eine Druckmodulation, für eine Blök— kierschutzexnrichtung in einer Baueinheit zusammenfaßbar 5/W.The dual-circuit brake booster with the characteristic Features of the main claim has the advantage that it is cheaper due to the lower effort, is. In addition, his weight is reduced. Furthermore, it is more fail-safe because of the smaller number of parts than known types. Finally, it is particularly suitable for an integrated design, with the function the braking force boost and the pressure procurement as well possibly also a pressure modulation, for a block Ski protection device can be combined in one unit 5 / W.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert.An embodiment of the invention is shown in the drawing and explained in more detail in the following description.

Beschreibung des AusführungsbeispielesDescription of the embodiment

Ein Bremskraftverstärker 1 ist zusammen mit einem Zweikreis-Hauptzylinder 2 in eine Bremsanlage eingebaut. Beide Teile 1 und 2 können aber auch voneinander getrennt sein. Im Bremskraftverstärker 1 sind zwei Bremsdruckregelventile 5 und 6 angeordnet und vom Bremskraftverstärker 1 nehmen zwei Kanäle 3 und k zweier Bremskreise I und II ihren Ausgang, die zu den Radzylindern führen.A brake booster 1 is installed in a brake system together with a dual-circuit master cylinder 2. Both parts 1 and 2 can, however, also be separate from one another. Two brake pressure regulating valves 5 and 6 are arranged in the brake booster 1 and two channels 3 and k of two brake circuits I and II take their output from the brake booster 1 and lead to the wheel cylinders.

Im Zweikreis-Hauptzylinder 2 ist ein erster Kolben- 7 für die Unterdrucksetzung des Bremskreises II und - durch eineIn the two-circuit master cylinder 2 is a first piston 7 for the pressurization of the brake circuit II and - by a

Feder 6 an diesem abgestützt - ein zweiter Kolben 9-mit

a spring 10 for pressurizing the brake circuit I is provided. Because of this connection in series, such a master cylinder 2 is therefore also called a tandem master cylinder. He-carries a refill container 11.

Gemäß der Erfindung stützt sich nun aber die Feder 10 des zweiten Kolbens 9 nicht am Gehäuse sondern an einem dritten Kolben 12 ab, der von hinten ebenfalls der Kraft einer Feder 13 ausgesetzt ist. Da die beiden Bremsdruckregelventile 5 und 6 durch den Druck des Hauptzylinders 2 betätigt werden, bildet der Kolben 12 mit der Feder 13 einen Wegsimulator 12 /1 3 s der für beide Bremskreise I und II
wirksam ist und der dem Fahrer das Bremsgefühl verbessert.According to the invention, however, the spring 10 of the second piston 9 is not supported on the housing but on a third piston 12, which is also subjected to the force of a spring 13 from behind. Since the two brake pressure regulating valves 5 and 6 are actuated by the pressure of the master cylinder 2, the piston 12 with the spring 13 forms a travel simulator 12/1 3 s for both brake circuits I and II
is effective and which improves the driver's braking feeling.

Jedem Bremsdruckregelventil 5 und 6 ist ein Schaltventil 1^ bzw. 15 beigeordnet, über welches bei intakter Druckmittelversorgung das vom Bremsdruckregelventil 5 bzw. 6
eingesteuerte Bremsdruckmittel zu den Radzylindern gelangt. In der entsprechenden Bremsleitung 3 bzw. k liegen je drei Magnetventile 16, 17s 18 bzw. 19» 20, 21, die zu einer
Blockierschutzeinrichtung 30 gehören, die mit nicht dargestellten Rad Sensoren und einem elektronischen Steuergerät in bekannter Weise das Blockieren der Fahrzeugräder beim Bremsen verhindert.A switching valve 1 ^ or 15 is assigned to each brake pressure regulating valve 5 and 6, via which, if the pressure medium supply is intact, the control valve 5 or 6
controlled brake pressure medium reaches the wheel cylinders. In the corresponding brake line 3 or k are three solenoid valves 16, 17s 18 and 19 »20, 21, which form one
Anti-lock device 30 include which, with wheel sensors (not shown) and an electronic control unit, prevents the vehicle wheels from locking during braking in a known manner.

In jedem Bremsdruckregelventil 5 "bzw. β gibt es einen vom Hauptzylinderdruck betätigbaren Steuerkolben 22 bzw. 23, der ein Schieberventil 2k bzw. 25 betätigt, das die Verbindung einer Druckbeschaffungseinrichtung mit den
Br emsleitungen 3, k überwacht. Die Druckbeschaffungseinrichtung besteht im wesentlichen aus einer Pumpe 26 und
einem Speicher 27·In each brake pressure regulating valve 5 ″ or β there is a control piston 22 or 23 which can be actuated by the master cylinder pressure and which actuates a slide valve 2k or 25, which connects a pressure supply device with the
Brake lines 3, k monitored. The pressure acquisition device consists essentially of a pump 26 and
a memory 27

Wenn die Druckbeschaffungseinrichtung 26/27 jedoch funktioniert, dann nimmt das Übervaehungsventil 28 seine andere Stellung ein, so daß der Wegsimulator 12/13 arbeiten kann.On the suction side of the pump 27 there is also a 2/2-way valve 28 as a Übervaehungsven.til, aas with failed Print procurement device 26/27 the path simulator 12/13 puts out of operation (shown position of the valve 28), and in the master cylinder 2 no way to be wasted and an additional one To avoid volume uptake with changed pedal characteristics. When the print procurement facility 26/27 works, however, then the overflow valve takes 28 its other position so that the travel simulator 12/13 can work.

Mit nur einem einzigen Wegsimulator ist die Zweikreisbremse gegenüber bekannten vereinfacht. Der geringere Aufwand vermindert auch das Gewicht. Die Ausfall-Sicherheit ist vergrößert.The dual-circuit brake has only a single travel simulator simplified compared to known. The lower effort also reduces the weight. Failure security is enlarged.
