Description
Die Erfindung betrifft eine Pumpenanordnung für eine eine Schlupfregeleinrichtung aufweisende Bremsanlage für Kraftfahrzeuge, mit einer Bremskraftverstärkerpumpe und einer hydraulischen Pumpe zum Betreiben der Schlupfregeleinrichtung, wobei die Bremskraftverstärkerpumpe und die hydraulische Pumpe von einem gemeinsamen Elektromotor angetrieben werden.The invention relates to a pump arrangement for a Brake system having a slip control device for Motor vehicles, with a brake booster pump and hydraulic pump for operating the slip control device, the brake booster pump and the hydraulic pump are driven by a common electric motor.
Eine derartige Pumpenanordnung ist aus der Bremsanlage nach der Druckschrift DE 44 16 833 A1 bekannt. Der beide Pumpen antreibende Elektromotor ist zwischen den Pumpen angeordnet und über beidseitig aus einem Motorgehäuse ragende Motorwellenabschnitte mit den jeweiligen Pumpenwellen verbunden. In dieser Druckschrift ist auch eine Ausführungsvariante erwähnt, wonach zwischen dem Elektromotor und der hydraulischen ABS-Pumpe ein Freilaufgetriebe vorgesehen ist, welches in einer Umdrehungsrichtung des Elektromotors eine Antriebsverbindung zwischen der Motorwelle und der hydraulischen Pumpe herstellt und in der entgegengesetzten Umdrehungsrichtung des Elektromotors ein Mit laufen der hydraulischen Pumpe mit der Unterdruckpumpe verhindert, indem die Antriebsverbindung zwischen Motorwelle und hydraulischer Pumpe entkoppelt wird (Freilauf).Such a pump arrangement is from the brake system the publication DE 44 16 833 A1 known. The two pumps driving electric motor is arranged between the pumps and protruding from a motor housing on both sides Motor shaft sections with the respective pump shafts connected. There is also one in this publication Design variant mentioned, after which between the electric motor and the hydraulic ABS pump a freewheel gear is provided, which is in a direction of rotation of the Electric motor a drive connection between the motor shaft and the hydraulic pump manufactures and in the opposite direction of rotation of the electric motor With the hydraulic pump run with the vacuum pump prevented by the drive connection between motor shaft and hydraulic pump is decoupled (freewheel).
Der vorliegenden Erfindung liegt hiervon ausgehend die Aufgabe zugrunde, eine Pumpenanordnung der eingangs beschriebenen Art dahingehend zu verbessern, daß die erwähnten Pumpen im Verlauf des Betriebs der Bremsanlage eine noch geringere Abnutzung erfahren.Based on this, the object of the present invention based on a pump arrangement of the type described above to improve in that the pumps mentioned in the course of the operation of the brake system an even lower wear Experienced.
Diese Aufgabe wird bei einer Pumpenanordnung der genannten Art erfindungsgemäß dadurch gelöst, daß in Abhängigkeit von der Drehrichtung des gemeinsamen Motors entweder die Bremskraftverstärkerpumpe oder die hydraulische Pumpe antreibbar ist.This object is achieved in a pump arrangement of the type mentioned solved according to the invention in that, depending on the Direction of rotation of the common motor either the Brake booster pump or the hydraulic pump is drivable.
Es wird also erfindungsgemäß vorgeschlagen, den gemeinsamen Betrieb von Bremskraftverstärkerpumpe und hydraulischer Pumpe zu vermeiden. Dies kann beispielsweise durch die Verwendung ans ich bekannter Freilaufgetriebe oder durch die Verwendung von Pumpen mit festgelegter Förderrichtung, wie zum Beispiel Zahnradpumpen, verwirklicht werden.It is therefore proposed according to the invention, the common one Operation of brake booster pump and hydraulic pump to avoid. This can be done, for example, by using it to the freewheel gear known to me or through the use of pumps with a fixed delivery direction, such as Gear pumps can be realized.
Die Steuerung der Drehrichtung des gemeinsamen Antriebsmotors kann in ans ich bekannter Weise durch Umpolen der Anschlußklemmen des Elektromotors unter Verwendung einer geeigneten Steuerung erfolgen, welche den Elektromotor im Normalbremsbetrieb in einer ersten Drehrichtung antreibt, in welcher die Bremskraftverstärkerpumpe angetrieben wird, und im Schlupfregel- oder ABS-Betrieb in der entgegengesetzten Richtung, in der die hydraulische ABS-Pumpe angetrieben wird.The control of the direction of rotation of the common drive motor can be reversed in the manner known to me Terminals of the electric motor using a suitable control take place, which the electric motor in Normal braking operation in a first direction of rotation drives in which the brake booster pump is driven, and in Slip control or ABS operation in the opposite Direction in which the hydraulic ABS pump is driven.
Bei der vorgeschlagenen Vorgehensweise erweist es sich als vorteilhaft, daß eine Medientrennung beibehaltenwerden kann und zum Einsatz verschiedener Betriebsmedien (Vakuum, Druckluft, Bremsflüssigkeit, Mineralöl) bei verschiedenen Betriebsdrücken (-0,9 bar, 6 bar, 60 bar, 200 bar) geeignet ist. Es findet ferner zu keinem Zeitpunkt eine Addition der jeweiligen Leistungsaufnahme der beiden Pumpen statt, da immer nur eine der Pumpen angetrieben wird.With the proposed approach, it turns out to be advantageous that media separation can be maintained and for the use of various operating media (vacuum, Compressed air, brake fluid, mineral oil) at various Operating pressures (-0.9 bar, 6 bar, 60 bar, 200 bar) are suitable is. There is also no addition of the respective power consumption of the two pumps instead, as always only one of the pumps is driven.
Es empfiehlt sich desweiteren, in der Verbindung zwischen der Verstärkerpumpe und dem Bremskraftverstärker einen hydraulischen oder pneumatischen Speicher vorzusehen, damit im Schlupfregel- oder ABS-Betrieb der Volumen- oder Druckbedarf des Verstärkers aus dem Speicher entnommen werden kann. Beim Wiederaufladen des Speichers durch die Bremskraftverstärker pumpe ist dann die hydraulische ABS-Pumpe vom Antrieb abgekoppelt, so daß die hydraulische Pumpe außerhalb des ABS-Betriebs keinerlei Verschleiß ausgesetzt ist.It is also recommended to use the connection between the Booster pump and the brake booster one hydraulic or pneumatic memory to provide, so in Slip control or ABS operation of volume or pressure requirements of the amplifier can be removed from the memory. At the Recharge the memory by the brake booster the pump is then the hydraulic ABS pump from the drive uncoupled so that the hydraulic pump outside the ABS operation is not exposed to any wear.
Im Hinblick auf eine kompakte Gestaltung einer Bremsanlage wird in Weiterbildung der Erfindung vorgeschlagen, die Pumpenanordnung so auszubilden, daß die Bremskraftverstärker pumpe und die hydraulische Pumpe über ihren Antriebsmotor mechanisch zu einer modularen Baueinheit gekoppelt sind. Hierdurch wird der insgesamt benötigte Bauraum erheblich reduziert, und es lassen sich Montagekosten einsparen.With regard to a compact design of a brake system is proposed in a further development of the invention Form the pump assembly so that the brake booster pump and the hydraulic pump via their drive motor are mechanically coupled to form a modular unit. As a result, the overall installation space required is considerable reduced, and assembly costs can be saved.
Es hat sich desweiteren als vorteilhaft erwiesen, daß der gemeinsame Antriebsmotor der Antriebsmotor der Brems kraftverstärkerpumpe ist, der erfahrungsgemäß leiser ist als der Antriebsmotor einer hydraulischen ABS-Pumpe und eine höhere Lebensdauer aufweist. Zum mechanischen Koppeln des Antriebsmotors der Bremskraftverstärkerpumpe mit der hydraulischen Pumpe ist eine Getriebeadaptervorrichtung zwischengeordnet, um ein schnittstellenkompatibles Zusammenfügen zu ermöglichen.It has also proven advantageous that the common drive motor the drive motor the brake is a booster pump, which experience has shown is quieter than the drive motor of a hydraulic ABS pump and one has a longer service life. For mechanical coupling of the Drive motor of the brake booster pump with the hydraulic pump is a gear adapter device subordinate to an interface compatible To allow joining.
Weitere Merkmale, Vorteile und Einzelheiten der Erfindung ergeben sich aus der zeichnerischen Darstellung und nachfolgenden Beschreibung einer Bremsanlage mit einer erfindungsgemäßen Pumpenanordnung und der schematischen Darstellung einer solchen Pumpenanordnung. In der Zeichnung zeigt:Further features, advantages and details of the invention result from the graphic representation and following description of a braking system with a pump arrangement according to the invention and the schematic Representation of such a pump arrangement. In the drawing shows:
Fig. 1 eine Bremsanlage mit einer erfindungsgemäßen Pumpenanordnung, und Fig. 1 shows a brake system with a pump arrangement according to the invention, and
Fig. 2 eine schematische Darstellung einer erfindungsgemäßen Pumpenanordnung. Fig. 2 is a schematic representation of a pump arrangement according to the invention.
Fig. 1 zeigt eine Bremsanlage mit einem ans ich bekannten pneumatischen Bremskraftverstärker 2 mit zwei Kammern, von denen eine Kammer 4 mit einer pneumatischen Unterdruck erzeugenden Pumpe 6 und die andere Kammer 8 über einen Anschluß 10 mit Atmosphäre verbindbar ist. Fig. 1 shows a brake system with a known to me pneumatic brake booster 2 with two chambers, of which one chamber 4 with a pneumatic vacuum pump 6 and the other chamber 8 via a connection 10 can be connected to the atmosphere.
Die Kammern 4 und 8 sind bei dem beispielhaft und schematisch dargestellten Bremskraftverstärker 2 durch eine nicht dargestellte Membran gegeneinander abgegrenzt. Wird ein Bremsvorgang durch Betätigen eines Bremspedals 12 eingeleitet, so wird eine Druckstange 14 in ein Ventilgehäuse 16 des Bremskraftverstärkers 2 gedrückt und betätigt ein Steuerventil, welches eine Verbindung zwischen den beiden Kammern 4 und 8 schließt und den Anschluß 10 der Kammer 8 zur Atmosphäre öffnet. Eine über die Druckstange 14 eingeleitete Kraft wird so in bekannter Weise in eine verstärkte auf einen Arbeitskolben 18 innerhalb eines schematisch angedeuteten Hauptzylinders 20 wirkende Ausgangskraft umgewandelt. Der Hauptzylinder 20 steht über hydraulische Bremsleitungen 22 mit Radbremsen 24 in Verbindung.The chambers 4 and 8 are delimited from one another in the brake booster 2, shown by way of example and schematically, by a membrane, not shown. If a braking process is initiated by actuating a brake pedal 12 , a push rod 14 is pressed into a valve housing 16 of the brake booster 2 and actuates a control valve which closes a connection between the two chambers 4 and 8 and opens the connection 10 of the chamber 8 to the atmosphere. A force introduced via the push rod 14 is thus converted in a known manner into an increased output force acting on a working piston 18 within a schematically indicated master cylinder 20 . The master cylinder 20 is connected to wheel brakes 24 via hydraulic brake lines 22 .
Die elektromotorisch angetriebene Unterdruckpumpe 6 ist Teil einer Pumpenanordnung 26, welche in Form einer modularen Baueinheit ausgebildet ist. Die Pumpenanordnung 26 umfaßt die Unterdruckpumpe 6, eine hydraulische zu einer nicht dargestellten Schlupfregeleinrichtung gehörenden ABS-Pumpe 28 sowie einen Elektromotor 30, der über jeweils ein Freilaufgetriebe 32, 34 mit der hydraulischen Pumpe 28 bzw. der Unterdruckpumpe 6 verbunden ist. Die Pumpenanordnung 26 ist so ausgebildet, daß bei laufendem Elektromotor 30 in der einen Drehrichtung die hydraulische ABS-Pumpe 28 und in der anderen Drehrichtung die pneumatische Unterdruckpumpe 34 für den Bremskraftverstärker 8 angetrieben wird. Wird also eine Pumpe angetrieben, so befindet sich das Freilaufgetriebe der anderen Pumpe im Freilauf, so daß diese nicht angetrieben wird.The vacuum pump 6 driven by an electric motor is part of a pump arrangement 26 which is designed in the form of a modular unit. The pump arrangement 26 includes the vacuum pump 6 , a hydraulic ABS pump 28 belonging to a slip control device, not shown, and an electric motor 30 , which is connected to the hydraulic pump 28 and the vacuum pump 6 via a freewheel gear 32 , 34, respectively. The pump arrangement 26 is designed such that when the electric motor 30 is running, the hydraulic ABS pump 28 is driven in one direction of rotation and the pneumatic vacuum pump 34 for the brake booster 8 in the other direction of rotation. So if one pump is driven, the freewheel gear of the other pump is in freewheel so that it is not driven.
Der Elektromotor 30 ist mit einer angedeuteten Steuereinheit 36 der nicht dargestellten Schlupfregeleinrichtung der Bremsanlage verbunden und wird von dieser in der einen oder anderen Drehrichtung angesteuert. Die Steuereinheit 36 ist mit einem die Bewegung der Druckstange 14 registrierenden Sensor 38 verbunden. Sobald eine Bewegung der Druckstange 14 registriert wird, d. h. eine Bremsung eingeleitet wird, wird der Elektromotor 30 über die Steuereinheit 36 mit Strom versorgt und in einer solchen Drehrichtung angetrieben, daß die Unterdruckpumpe 6 anläuft. Die Unterdruckpumpe 6 evakuiert die eine Kammer 4, wobei in der hierfür vorgesehenen Verbindungsleitung ein Rückschlagventil 40 vorgesehen ist, um zu verhindern, daß nach Beendigung eines Bremsvorgangs bei Abschalten der Unterdruckpumpe 6 der Unterdruck in der Kammer 4 zusammenbricht.The electric motor 30 is connected to an indicated control unit 36 of the slip control device (not shown) of the brake system and is controlled by it in one or the other direction of rotation. The control unit 36 is connected to a sensor 38 which registers the movement of the push rod 14 . As soon as movement of the push rod 14 is registered, ie braking is initiated, the electric motor 30 is supplied with power via the control unit 36 and driven in such a direction of rotation that the vacuum pump 6 starts. The vacuum pump 6 evacuates one chamber 4 , a check valve 40 being provided in the connecting line provided for this purpose, in order to prevent the vacuum in the chamber 4 from breaking down when the vacuum pump 6 is switched off when a braking process has ended.
Während eines Schlupfregel- oder ABS-Vorgangs wird der Motor 30 über die Steuereinheit 36 kontinuierlich in zur vorstehend erwähnten Drehrichtung entgegengesetzter Drehrichtung angetrieben, um über die hydraulische ABS-Pumpe 28 den für einen Schlupfregelvorgang erforderlichen hydraulischen Druck bereitzustellen. In diesem ABS-Betrieb wird die Unterdruckpumpe 6 nicht angetrieben.During a slip control or ABS operation, the motor 30 is continuously driven via the control unit 36 in the opposite direction of rotation to the above-mentioned direction of rotation in order to provide the hydraulic pressure required for a slip control operation via the hydraulic ABS pump 28 . In this ABS operation, the vacuum pump 6 is not driven.
Fig. 2 zeigt in schematischer Darstellung eine modulare Pumpenanordnung 42 bestehend aus einer Bremskraftverstärkerpumpe 44 mit einem Antriebsmotor 46, einem Getriebeadapter 48 und einer hydraulischen ABS-Pumpenanordnung 50, deren Antriebsmotor 52 entfernt wurde und die somit über den Getriebeadapter 48 von dem Antriebsmotor 46 der Bremskraftverstärkerpumpe 44 antreibbar ist. FIG. 2 shows a schematic illustration of a modular pump arrangement 42 consisting of a brake booster pump 44 with a drive motor 46 , a gear adapter 48 and a hydraulic ABS pump arrangement 50 , the drive motor 52 of which has been removed and which is thus removed from the drive motor 46 of the brake booster pump via the gear adapter 48 44 is drivable.
