Description
Die vorliegende Erfindung betrifft eine Anbindung eines als Zentralausrücker ausgebildeten Nehmerzylinders an eine Kupplung bzw. an deren Gehäusedeckel gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a connection of a slave cylinder designed as a central release cylinder to a clutch or to its housing cover according to the preamble of
Ein um eine Getriebeeingangswelle angeordneter Nehmerzylinder oder auch Zentralausrücker ist mit einem Ausrücklager ausgestattet und bildet einen Teil einer hydraulischen Strecke in Verbindung mit einem Geberzylinder und einer diese verbindenden Hydraulikleitung.A slave cylinder or also a central release bearing arranged around a transmission input shaft is equipped with a release bearing and forms part of a hydraulic path in connection with a master cylinder and a hydraulic line connecting it.
Bei Aktivierung des Geberzylinders wird das in diesem befindliche Druckfluid durch die Hydraulikleitung auf den Zentralausrücker übertragen und löst damit eine Axialverschiebung des Ausrücklagers aus. Dieses Ausrücklager besteht im Wesentlichen aus einem drehstarr auf einer Schiebehülse angeordneten Lagerring und einer mit der Drehzahl der Kupplung rotierenden Lagerschale, wobei zwischen diesen beiden Bauteilen sich um eine gemeinsame Rotationsachse drehende Wälzkörper untergebracht sind. Die Verschiebung des Ausrücklagers bewirkt die Auslenkung einer Tellerfeder, die das Ein- und Ausrücken der Kupplung steuert.When the master cylinder is activated, the pressure fluid located in it is transferred through the hydraulic line to the central release mechanism and thus triggers an axial displacement of the release bearing. This release bearing consists essentially of a torsionally rigid bearing ring arranged on a sliding sleeve and a bearing shell rotating at the speed of the clutch, with rolling elements rotating about a common axis of rotation being accommodated between these two components. The displacement of the release bearing causes a disc spring to deflect, which controls the engagement and disengagement of the clutch.
Im eingebauten Zustand kann das Ausrücklager einem sogenannten Zungenschlag, d.h. einem Axialschlag der Tellerfederzungen ausgesetzt sein, der den Verschleiß des Ausrücklagers erhöht und damit zu einer Verringerung der Lebensdauer führt.When installed, the release bearing can be exposed to so-called tongue runout, i.e. axial run-out of the diaphragm spring tongues, which increases wear on the release bearing and thus leads to a reduction in service life.
Achsversatz und Winkelfehler zwischen Getriebeeingangswelle und Führungshülse eines Zentralausrückers können außerdem bei der Montage von Getriebe und Verbrennungsmotor zu Beschädigungen führen, was im Extremfall zum Ausfall des Zentralausrückers im Betrieb führen kann.Axial offset and angular errors between the gearbox input shaft and the guide sleeve of a central slave cylinder can also lead to damage during the assembly of the transmission and combustion engine, which in extreme cases can lead to failure of the central slave cylinder during operation.
Weiterhin können die beiden durch die Kupplung getrennten Antriebskomponenten einen achsparallelen Versatz der kraftübertragenden Wellen aufweisen, der durch eine Selbstzentrierung des Ausrücklagers kompensiert werden muss, da ansonsten das Ausrücklager einem erhöhten Verschleiß ausgesetzt ist und Komforteinbußen durch Vibrationen auftreten.Furthermore, the two drive components separated by the clutch can have an axially parallel offset of the force-transmitting shafts, which must be compensated for by self-centering the release bearing, since otherwise the release bearing is exposed to increased wear and comfort losses due to vibrations occur.
Zur Kompensation bzw. zum Ausgleich eines solchen nachteiligen Zungenschlages und des axialen Versatzes der kraftübertragenden Wellen werden verschiedene Lösungen vorgeschlagen.Various solutions are proposed to compensate or compensate for such a disadvantageous flap of the tongue and the axial offset of the force-transmitting shafts.
Die
Um über eine Ausrückvorrichtung ohne zusätzliche Einrichtung an deren Ausrücklager eine Kompensation des Schlages der Tellerfederzungen und die Eliminierung des Winkelversatzes des Ausrücklagers gegenüber der Rotationsachse zu erreichen, wird in der

Eine Anbindung gemäß dem Oberbegriff des Anspruchs 1 ist in der
Daher besteht die Aufgabe der Erfindung darin, die Anbindung eines Zentralausrückers an einen Kupplungsdeckel so auszuführen, dass durch diese die Übertragung eines achsparallelen Versatzes der kraftübertragenden Wellen, sowie Taumelbewegungen infolge des Tellerfederzungenschlages auf den Zentralausrücker vermieden wird.The object of the invention is therefore to implement the connection of a central release device to a clutch cover in such a way that this the transmission of an axially parallel offset of the force-transmitting shafts, as well as wobbling movements due to the disc spring tongue on the central slave cylinder, is avoided.
Diese Aufgabe wird mit einem Zentralausrücker mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with a central clutch release device with the features of
