Abstract
Description
Die Erfindung betrifft eine Kupplungsbetätigungsvorrichtung für eine Kupplung eines Kraftfahrzeugs, insbesondere für eine Doppelkupplung, mit einem Nehmerzylinder und mit einer Kühlmittelleitung, wobei in dem Nehmerzylinder ein Kolben geführt oder führbar ist.The invention relates to a clutch actuating device for a clutch of a motor vehicle, in particular for a double clutch, with a slave cylinder and with a coolant line, wherein in the slave cylinder, a piston is guided or feasible.
Im Stand der Technik sind verschiedene Kupplungsbetätigungsvorrichtungen bekannt.Various clutch actuation devices are known in the art.

Aus der gattungsgemäßen
Die eingangs genannten Kupplungsbetätigungsvorrichtungen sind noch nicht optimal ausgebildet. Die im Stand der Technik bekannten Kupplungsbetätigungsvorrichtungen sind aufwendig zu montieren. Die Druckmittelleitung und/oder die Kühlmittelleitungen müssen separat montiert werden. Es ist darauf zu achten, dass die die Kühlmittelleitung und/oder die Druckmittelleitung abgedichtet sind, um einen Austritt von Druckmittel und/oder Kühlmittel zu verhindern.The above-mentioned clutch actuating devices are not yet optimally formed. The known in the art clutch actuating devices are expensive to assemble. The pressure medium line and / or the coolant lines must be mounted separately. It is important to ensure that the coolant line and / or the pressure medium line are sealed to prevent leakage of pressure medium and / or coolant.
Der Erfindung liegt daher die Aufgabe zugrunde, die zuvor genannte Kupplungsbetätigungsvorrichtung bzw. eine Kupplung so auszugestalten und weiterzubilden, dass die Gefahr von Undichtigkeiten vermindert und eine aufwendige Montage vermieden ist.The invention is therefore based on the object, the aforementioned clutch actuating device or a clutch to design and further develop that the risk of Leakage reduced and a complex assembly is avoided.
Diese der Erfindung zugrunde liegende Aufgabe wird nun dadurch gelöst, dass eine Gehäusebaueinheit vorgesehen ist, wobei die Gehäusebaueinheit den Nehmerzylinder, die Kühlmittelleitung und mindestens eine Druckmittelleitung aufweist. Die Druckmittelleitung mündet insbesondere in den Nehmerzylinder. Die Gehäusebaueinheit weist mindestens eine Kühlmittelleitung und mindestens eine Druckmittelleitung auf. Die Kühlmittelleitung und die Druckmittelleitung sind fest mit dem Nehmerzylinder verbunden. Die Gehäusebaueinheit weist den Nehmerzylinder zur Führung eines Kolbens auf. Der Nehmerzylinder ist vorzugsweise ringförmig ausgebildet. Der Kolben ist entsprechend ebenfalls ringförmig ausgebildet. Der Nehmerzylinder ist zentral angeordnet. Der Nehmerzylinder kann aus einem Stahlblech gefertigt sein. Das Zylindergehäuse kann aus Kunststoff hergestellt, insbesondere gespritzt sein. Die Druckmittelleitung und/oder die Kühlmittelleitung können durch zum Beispiel metallische Rohre gebildet sein, die mit einem Kunststoff umspritzt sind. In alternativer Ausgestaltung können die Druckmittelleitung und/oder die Kühlmittelleitung als Kunststoffteile direkt an den Nehmerzylinder angespritzt sein oder durch Ultraschallschweißen mit dem Nehmerzylinder verbunden sein. Diese mehrfunktionale Gehäusebaueinheit mindert die Gefahr von Undichtigkeiten und ist einfach zu montieren. Die Gehäusebaueinheit ist vorzugsweise mit einem entsprechenden gestalteten Kupplungsdeckel insbesondere fest verbunden. Die Gehäusebaueinheit kann in den Deckel eingeklipst, eingeschraubt oder komplett mit diesem verspritzt sein. Die Druckmittelleitung und/oder die Kühlmittelleitung können sich am Kupplungsdeckel abstützen. Der Kupplungsdeckel kann als Gussdeckel ausgeführt sein. Der Deckel kann mindestens eine sich im Wesentlichen parallel zur Kühlmittelleitung erstreckende Rippe aufweisen, so dass die Kühlmittelleitung, insbesondere in Umfangsrichtung an der entsprechenden Rippe abgestützt ist. Die Kühlmittelleitung und/oder die Druckmittelleitung können sich im Wesentlichen innen an dem Deckel anliegend erstrecken. Die Kühlmittelleitung weist einen sich im Wesentlichen nach radial außen erstreckenden Abschnitt auf und mündet in einem sich im Wesentlichen in axialer Richtung erstreckenden Endabschnitt. Dieser Endabschnitt greift insbesondere in einen entsprechenden Kühlmittelkanal ein. Dort kann dieser Endabschnitt mit einem Dichtring abgedichtet sein. Der Deckel greift hierbei um alle Dichtstellen herum, wobei die Gehäusebaueinheit separat vom Deckel abgedichtet ist. Die Gehäusebaueinheit kann eine Aufnahme für ein Entlüftungsventil aufweisen. Die Aufnahme kann sich im Wesentlichen parallel zu einem Boden des Nehmerzylinders erstrecken und in den Druckraum des Nehmerzylinders münden. Der Deckel weist insbesondere einen Vorsprung zur formschlüssigen Halterung des Entlüftungsventils auf. Dieser Vorsprung bildet einen Anschlag für das Entlüftungsventil. Sofern die Gehäusebaueinheit nicht komplett in den Deckel eingespritzt ist, kann der Deckel einen Zentriersitz aufweisen, wobei die Gehäusebaueinheit insbesondere einen Zentrierkragen aufweist, und wobei der Zentrierkragen an dem Zentriersitz des Deckels abgestützt ist. Der Deckel kann eine zentrale Öffnung aufweisen, wobei in der zentralen Öffnung ein Lager an dem Deckel anliegt. Zur Abstützung des Lagers kann der Deckel einen Lageranschlagskragen aufweisen. Die eingangs genannten Nachteile sind daher vermieden und entsprechende Vorteile sind erzielt.This object of the invention is based is achieved in that a housing assembly is provided, wherein the housing assembly comprises the slave cylinder, the coolant line and at least one pressure medium line. The pressure medium line opens in particular in the slave cylinder. The housing module has at least one coolant line and at least one pressure medium line. The coolant line and the pressure medium line are firmly connected to the slave cylinder. The housing assembly has the slave cylinder for guiding a piston. The slave cylinder is preferably annular. The piston is also correspondingly annular. The slave cylinder is arranged centrally. The slave cylinder can be made of a steel sheet. The cylinder housing can be made of plastic, in particular be sprayed. The pressure medium line and / or the coolant line can be formed by, for example, metallic tubes, which are encapsulated with a plastic. In an alternative embodiment, the pressure medium line and / or the coolant line can be molded as plastic parts directly to the slave cylinder or be connected by ultrasonic welding to the slave cylinder. This multi-functional enclosure reduces the risk of leaks and is easy to install. The housing assembly is preferably fixedly connected in particular to a correspondingly designed clutch cover. The housing assembly can be clipped into the lid, screwed or sprayed completely with this. The pressure medium line and / or the coolant line can be supported on the clutch cover. The clutch cover can be designed as a cast cover. The cover may have at least one rib extending substantially parallel to the coolant line, so that the coolant line, in particular in the circumferential direction, is supported on the corresponding rib. The coolant line and / or the pressure medium line may extend substantially inwardly against the cover. The coolant line has a section extending essentially radially outwards and terminating in an end section extending essentially in the axial direction. This end section engages in particular in a corresponding coolant channel. There, this end portion may be sealed with a sealing ring. The lid engages around all sealing points, wherein the housing assembly is sealed separately from the lid. The housing assembly may include a receptacle for a vent valve. The receptacle may extend substantially parallel to a bottom of the slave cylinder and open into the pressure chamber of the slave cylinder. The lid has in particular a projection for the positive retention of the vent valve. This projection forms a stop for the vent valve. If the housing assembly is not completely injected into the lid, the lid may have a centering, wherein the housing assembly in particular has a centering collar, and wherein the centering collar is supported on the centering seat of the lid. The lid may have a central opening, wherein in the central opening a bearing rests on the lid. To support the bearing, the cover may have a Lageranschlagskragen. The aforementioned disadvantages are therefore avoided and corresponding advantages are achieved.
