schlupfregler hat ein Magnetventil, das während der Antriebsschlupfregelung die Verbindung zwischen dem Hauptzylinder und dem Steuerventil auftrennt und den Druckspeicher dann an den Eingang des Steuerventils anschaltet, mit dem die Bremsdruckvariation - gesteuert von einer Steuerschaltung im Sinne einer Antriebsschlupf-Unterdrückung durchgeführt wird.slip regulator has a solenoid valve that operates during traction control the connection between the master cylinder and the control valve is disconnected and the pressure accumulator then to the input of the control valve with which the brake pressure variation - controlled by a control circuit in the Meaning of a drive slip suppression is carried out.
Nun ist es aber so, daß für den Antriebsschlupfregler ein Druckspeicher mit hohem Druck benötigt wird. Beim Laden dieses Speichers entsteht das Problem, daß beim Ansaugen Unterdruck auftreten kann^ durch den Gasblasen in der Pumpensaugleitung entstehen, was zum Ausfall der Pumpe führen kann.But now it is so that for the traction controller a Accumulator with high pressure is needed. When loading this memory, the problem arises that when sucking Negative pressure can occur ^ due to the gas bubbles in the pump suction line arise, which can lead to failure of the pump.

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
Eine hydraulische Bremsanlage hat einen hydraulischen Tandem-Hauptzylinder 1 . Von diesem nehmen zwei Brerasleitungen ihren Ausgang, von denen eine zu den Bremszylindern nicht angetriebener Vorderräder und die andere Bremsleitung 2 mit zwei Bremszylindern 3 und k zweier über ein Differential 5 angetriebener Räder 6 und T verbunden ist. Vor den Rad-Bremszylindern 3 und h teilt sich die Bremsleitung 2 in zwei Leitungszweige 2' und 2" auf, und in jeden Leitungszweig 2' bzw. 2" ist ein 3/3-Wege-Magnetventil 8 bzw. 9 als Steuerventil eingesetzt, die beide in Richtung Hauptzylinder 1 über je ein Rückschlagventil 10 bzw. 11 umgehbar sind.A hydraulic brake system has a hydraulic tandem master cylinder 1. From this, two brake lines take their exit, one of which is connected to the front wheels not driven to the brake cylinders and the other brake line 2 is connected to two brake cylinders 3 and k of two wheels 6 and T driven via a differential 5. In front of the wheel brake cylinders 3 and h , the brake line 2 is divided into two line branches 2 'and 2 ", and a 3/3-way solenoid valve 8 or 9 is used as a control valve in each line branch 2' or 2", both of which can be bypassed in the direction of the master cylinder 1 via a check valve 10 and 11, respectively.
Jedes 3/3-Wege-Magnetventil 8 bzw. 9 hat einerseits einen Anschluß 12 bzw. 13 für je eine Rückleitung 1^ bzw. 15, die Verbindung mit einer Hochdruckpumpe 16 haben, und andererseits einen Anschluß 17 bzw. 18 für die Bremsleitungszweige 2' und 2", an die über eine Druckleitung 19 die Druckseite der Hochdruckpumpe 16 angeschlossen ist.Each 3/3-way solenoid valve 8 or 9 has on the one hand a connection 12 or 13 for a return line 1 ^ or 15, which are connected to a high pressure pump 16, and on the other hand, a connection 17 or 18 for the brake line branches 2 'and 2 ", to which the pressure side of the high-pressure pump 16 is connected via a pressure line 19 is.
Die Rückleitungen 1U und 15 führen über eine gemeinsame Rückleitung 20 zu einem Speicherladeventil 21. Dort sind ein Rückschlagventil 22, ein Überströmventil 23 und ein Niederdrückspeicher 2h vorgesehen.The return lines 1U and 15 lead via a common return line 20 to an accumulator charging valve 21. A check valve 22, an overflow valve 23 and a low pressure accumulator 2h are provided there.

In der Bremsleitung 2 liegt ein 3/2-Wege-Umschalt-Magnetventil 25, das in seiner einen (gezeichneten) Stellung einen Durchgang für die Bremsleitung 2 bildet und das in seiner zweiten, nach Einschaltung seines Magneten erreichten Stellung eine Verbindung der an die Druckleitung 19 angeschlossenen Bremsleitungszweige 2' und 2" mit einem Hochdruckspeicher 26 und einem Druckschalter 27 herstellt.A 3/2-way switchover solenoid valve is located in the brake line 2 25, which in its one (shown) position forms a passage for the brake line 2 and that in its second position, reached after switching on its magnet, connects the to the pressure line 19 connected brake line branches 2 'and 2 "with a high pressure accumulator 26 and a pressure switch 27 manufactures.
Der Hauptzylinder 1 ist in üblicher Weise kombiniert mit einem Nachfüllbehälter 28, der in zwei Kammern 29 und 30 aufgeteilt ist, die beide über getrennte Leitungen 31 und 32 an den Hauptzylinder 1 angeschlossen sind. In die Leitung 31 ist eine Niederdruckpumpe 33 eingesetzt, die von einem Elektro-Motor 33' angetrieben wird und die im Stillstand einen drucklosen Durchlauf von Bremsflüssigkeit in beiden Richtungen gestattet. Um dies zu erreichen, ist sie als hydrodynamische Pumpe, z.B. als Kreiselpumpe oder Fliehkörper-Pumpe ausgebildet. In der Praxis werden die Leitungen und 32 als Kanäle erstellt, die Niederdruckpumpe 33 wird unmittelbar in den Nachfüllbehälter 28 eingebaut und der Antriebs-Elektro-Motor 33' wird außerhalb des Nachfüllbehälters 28, also "im Trocknen" angeordnet.The master cylinder 1 is combined in the usual way with a refill container 28, which is arranged in two chambers 29 and 30, both of which are connected to the master cylinder 1 via separate lines 31 and 32 are. A low-pressure pump 33, which is driven by an electric motor 33 ', is inserted into the line 31 and which allows a pressureless flow of brake fluid in both directions at standstill. To achieve this, it is used as a hydrodynamic pump, e.g. as a centrifugal pump or centrifugal pump educated. In practice, the lines 16 and 32 are created as channels that the low pressure pump 33 becomes built directly into the refill container 28 and the Drive electric motor 33 'is outside of the refill container 28, so arranged "in the dry".
WirkungsweiseMode of action
Beim gewöhnlichen Bremsen ist der Durchgang von Bremsflüssigkeit durch die Niederdruckpumpe 33 und durch das Umschalt-Magnetventil 25 hindurch unbeeinflußt.In ordinary braking, the passage of brake fluid through the low pressure pump 33 and through the Changeover solenoid valve 25 unaffected therethrough.
-ζ--ζ-
Neigt eines der Räder 6 oder 7 zum Blockieren, so geben an den Rädern angeordnete, nicht dargestellte Sensoren Signale an das entsprechende 3/3-Wege-Magnet-Steuerventil; und dieses Ventil schaltet dann entweder in seine zweite Stellung (Druckhalten) oder in seine dritte Stellung (Druckabbau) . Gleichzeitig mit dem 3/3-Wege-Magnetventil wird auch die Hochdruckpumpe 16 eingeschaltet, um die Entlastungs-Flüssigkeitsmenge über die Bremsleitung 2", 2 an den Hauptzylinder 1 zurückzugeben.If one of the wheels 6 or 7 tends to lock, sensors (not shown) located on the wheels send signals to the corresponding 3/3-way solenoid control valve ; and this valve then switches either into its second position (pressure holding) or into its third position (pressure reduction). At the same time as the 3/3-way solenoid valve, the high-pressure pump 16 is also switched on in order to return the relief fluid volume to the master cylinder 1 via the brake line 2 ″, 2.
Dreht beim Anfahren eines der Räder 6 oder T z.B. Rad 6 durch, so erfaßt sein Sensor diesen Fehler und gibt ein Signal an das Umschaltventil 25 und an das 3/3-Wege-Magnet-Steuerventil 9 des nicht durchdrehenden Rades. Die Ventile schalten um, wodurch einerseits der Hochdruck-Speicher 26 mit den Bremsleitungszweigen 2' und 2" verbunden wird, andererseits aber das 3/3-Wege-Magnetventil 9 in die Druckhalten-Stellung umschaltet, so daß die Bremsflüssigkeit nur über das nicht umgeschaltete 3/3-Wege-Magnetventil 8 zu dem Bremszylinder 3 des durchdrehender. Rades 6 gelangen kann. Das andere Rad 7 kann dann Drehkraft abgeben und das Fahrzeug fortbewegen. Die jeweilige Druckhöhe wird mittels einer nicht dargestellten Steuerschaltung in Abhängigkeit vom festgestellten Antriebsschlupf variiert. When starting one of the wheels 6 or T, e.g. wheel 6 turns by, its sensor detects this error and sends a signal to the switching valve 25 and to the 3/3-way solenoid control valve 9 of the wheel that is not spinning. The valves switch over, whereby on the one hand the high pressure accumulator 26 is connected to the brake line branches 2 'and 2 ", but on the other hand the 3/3-way solenoid valve 9 switches to the pressure hold position, so that the brake fluid only passes through the 3/3-way solenoid valve that has not been switched 8 to the brake cylinder 3 of the spinning. Wheel 6 can get. The other wheel 7 can then torque hand in and move the vehicle. The respective pressure level is determined by means of a control circuit (not shown) varies depending on the determined drive slip.
Es muß jedoch sichergestellt werden, daß zur Antriebsschlupfregelung der Hochdruck-Speicher 26 geladen ist. Dies wird erreicht in Verbindung mit der Niederdruckpumpe 33 , die zur Erzeugung eines Vordruckes in der Saugleitung der Hochdruckpumpe verwendet wird.However, it must be ensured that the drive slip control the high pressure accumulator 26 is charged. This is achieved in conjunction with the low pressure pump 33, which is used to generate a pre-pressure in the suction line of the high-pressure pump.
