Im Stand der Technik sind unterschiedlich ausgebildete Aktuator-Anordnungen für Kraftfahrzeuge bekannt, insbesondere auch für Hybrid-Kraftfahrzeuge. Im Allgemeinen weisen derartige Hybrid-Kraftfahrzeuge ein Hybrid-Antriebsmodul mit einem Elektromotor und einer Trennkupplung auf, die entweder in Serie, also sequentiell nacheinander oder parallel zu einem Verbrennungsmotor bzw. mit einem Getriebe derart gekoppelt sind, dass das Kraftfahrzeug entweder mit Hilfe des Verbrennungsmotors oder mit Hilfe des Elektromotors betrieben werden kann. Damit beide Betriebsweisen realisiert werden können, weist insbesondere das Hybrid-Antriebsmodul auch eine Trennkupplung auf, um den Elektromotor vom Getriebe und/oder vom Verbrennungsmotor abzukoppeln. Diese Trennkupplung, auch „K0-Kupplung" genannt, ist hydraulisch betätigbar, insbesondere ist eine mit der Trennkupplung zusammenwirkende Ausrückvorrichtung vorgesehen, die strömungstechnisch mit der Aktuatoreinheit verbunden ist.in the State of the art are differently formed actuator arrangements for motor vehicles known, especially for Hybrid vehicles. In general, such hybrid vehicles a hybrid drive module with an electric motor and a disconnect clutch on, either in series, sequentially in succession or in parallel coupled to an internal combustion engine or with a transmission such are that the motor vehicle either with the help of the internal combustion engine or can be operated by means of the electric motor. So both Operating modes can be realized, in particular the Hybrid drive module also a disconnect clutch to the electric motor from the transmission and / or decouple from the combustion engine. This separating clutch, also called "K0 coupling", is hydraulic operable In particular, a cooperating with the separating clutch release device provided, the fluidically connected to the actuator unit.
Zumeist wird bei derartigen Systemen zur Betätigung der Ausrückvorrichtung bzw. der Tennkupplung des Hybrid-Antriebsmodules ein separat hierfür ausgelegtes Hydrauliksystem realisiert, mit dessen Hilfe dann die Trennkupplung ein- bzw. auskuppelbar bzw. die Ausrückvorrichtung zum Ein- bzw. Ausrücken der Trennkupplung hydraulisch betätigbar ist. Dies bedeutet einen hohen Wartungsaufwand sowie einen großen Raumbedarf für einen entsprechenden Vorratsbehälter zur hydraulischen Versorgung der Aktuatoreinheit. Die damit verbunden Kosten sind damit sehr hoch und noch nicht optimal.mostly is used in such systems for actuating the release device or the Tennkupplung the hybrid drive module separately designed for this purpose Hydraulic system realized, with the help of which then the separating clutch on or disengageable or the release device for engagement or disengagement of the Disconnect is hydraulically actuated. This means a high maintenance and a large space requirement for one corresponding reservoir for hydraulic supply of the actuator unit. The associated Costs are very high and not optimal.
Der Erfindung liegt daher die Aufgabe zugrunde, die eingangs genannte Aktuator-Anordnung derart auszugestalten und weiterzubilden, dass die eingangs genannten Nachteile vermieden sind, insbesondere der Wartungsaufwand sowie die damit verbundenen Kosten und auch der Raumbedarf zur Anordnung der einzelnen Komponenten verringert sind.Of the Invention is therefore the object of the aforementioned Actuator arrangement in such a way and further develop that the disadvantages mentioned are avoided, in particular the Maintenance and the associated costs and also the Space requirements for the arrangement of the individual components are reduced.
Die zuvor aufgezeigte Aufgabe ist nun dadurch gelöst, dass die Aktuatoreinheit als Spindelaktuator ausgeführt ist und als Vorratsbehälter der Bremsflüssigkeitsbehälter des Kraftfahrzeuges verwendet wird, wobei der Spindelaktuator mit dem Bremsflüssigkeitsbehälter hydraulisch verbunden ist. Hierdurch können die im Stand der Technik bisher bekannten Nachteile vermieden werden. Dadurch, dass nämlich zunächst der bereits im Kraftfahrzeug vorgesehene Bremsflüssigkeitsbehälter als Vorratsbehälter zur hydraulischen Versorgung der Aktuatoreinheit verwendet wird, entfällt der Raumbedarf für die Anordnung eines zusätzlichen weiteren separaten Vorratsbehälters, der nun nicht mehr notwendig ist. Dadurch ist auch der Wartungsaufwand erheblich verringert. Insbesondere können auch die Kosten bei der Erstbefüllung von nur einem Behälter, nämlich – nunmehr nur noch – dem Bremsflüssigkeitsbehälter entsprechend eingespart werden, der vzw. mit Betriebsmittel, insbesondere Hydraulikmittel nur noch durch einen Arbeitsschritt befüllt werden muss, anders als bisher im Stand der Technik. Es kann nun auch für die Aktivierung der Bremse des Kraftfahrzeuges, sowie für die Aktivierung/Deaktivierung der Kupplung nunmehr das gleiche Betriebsmittel, also das gleiche Medium verwendet werden, so dass auch der weiteren zukünftigen Wartung das Betriebsmittel, also die Hydraulikflüssigkeit für den Bremskreislauf sowie für das Hydrauliksystem der Trennkupplung nunmehr in einem einzigen Arbeitsschritt ausgetauscht werden kann. Auch durch die bereits bestehende Überwachung des Bremskreislaufsystems kann nun auch das Hydrauliksystem der Trennkupplung überwacht werden. Für die Aktivierung, insbesondere das Ausrücken der Trennkupplung, insbesondere der K0-Kupplung des Hybrid-Antriebsmoduls sowie für die Aktivierung der Bremse des Kraftfahrzeuges kann nun auf den gleichen Vorratsbehälter zurückgegriffen werden. Auch dadurch, dass die Aktuatoreinheit als Spindelaktuator ausgeführt ist, in Kombination mit dem Merkmal, dass nunmehr der Spindelaktuator durch den Bremsflüssigkeitsbehälter hydraulisch versorgt wird, ergeben sich bei den Anordnungsmöglichkeiten entscheidende bauraumoptimierte sowie wirkungstechnische Vorteile, die im Folgenden noch erläutert werden sollen. Im Ergebnis sind die eingangs genannten Nachteile vermieden und entsprechende Vorteile erzielt.The previously indicated object is now achieved in that the actuator unit designed as Spindelaktuator is and as a reservoir the brake fluid reservoir of the Motor vehicle is used, wherein the Spindelaktuator with the brake fluid reservoir hydraulically connected is. This allows the disadvantages known in the prior art are avoided. Because, that is first the already provided in the motor vehicle brake fluid reservoir as reservoir used for hydraulic supply of the actuator unit, deleted the space required for the Arrangement of an additional another separate storage container, which is no longer necessary. This is also the maintenance significantly reduced. In particular, the costs in the Initial filling from just one container, namely - now only - the Brake fluid reservoir accordingly be saved, the vzw. with operating means, in particular hydraulic means only has to be filled by one step, unlike previously in the art. It can now also for the activation of the brake of the motor vehicle, as well as for the activation / deactivation of the clutch now the same equipment, So the same medium can be used, so also the other one future Maintenance the equipment, so the hydraulic fluid for the brake circuit and for the Hydraulic system of the clutch now replaced in a single step can be. Also due to the already existing monitoring of the brake circuit system Now also the hydraulic system of the separating clutch can be monitored become. For the activation, in particular the disengagement of the separating clutch, in particular the K0 coupling of the hybrid drive module as well as for activation the brake of the motor vehicle can now access the same reservoir become. Also in that the actuator unit as Spindelaktuator accomplished is, in combination with the feature that now the Spindelaktuator through the brake fluid reservoir hydraulically is supplied, resulting in the arrangement possibilities crucial space-optimized as well as effective technical advantages, which are explained below should. As a result, the aforementioned disadvantages are avoided and achieved corresponding advantages.
