Abstract
Description
Die Erfindung betrifft einen Zentralausrücker, insbesondere zur Betätigung mindestens einer Reibungskupplung in einem Antriebsstrang eines Kraftfahrzeuges zum wahlweisen Trennen und Verbinden zweier Wellen, bestehend aus einem konzentrisch um eine Antriebswelle angeordneten Gehäuse, in dem ein ringförmiger Kolben geführt ist, an dessen einem Ende ein Ausrücklager angeordnet ist, das sich an der Kupplung abstützt.The The invention relates to a Zentralausrücker, in particular for actuating at least one friction clutch in one Drive train of a motor vehicle for selectively separating and Connecting two waves, one concentric around one Drive shaft arranged housing in which an annular Piston is guided, at one end of a release bearing is arranged, which is supported on the coupling.
Dieser mit einem Ausrücklager ausgestattete Kolben eines Zentralausrückers bzw. konzentrisch um eine Getriebeeingangswelle angeordnete Nehmerzylinder (CSC-Concentric slave cylinder) bildet einen Teil einer hydraulischen Strecke in Verbindung mit einem Geberzylinder und einer beide Zylinder verbindenden Hydraulikleitung.This equipped with a release bearing piston a Zentralausrückers or concentrically about a transmission input shaft arranged slave cylinder (CSC Concentric slave cylinder) forms part of a hydraulic Track in conjunction with a master cylinder and a cylinder connecting both Hydraulic line.
Bei Aktivierung des Geberzylinders wird das in diesem befindliche Druckfluid durch die Hydraulikleitung auf den Kolben des Zentralausrückers übertragen und löst damit eine Axialverschiebung des Ausrücklagers aus. Dieses Ausrücklager besteht im Wesentlichen aus einem drehstarr auf einer Führungshülse 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. Eine axiale Verschiebung des Ausrücklagers bewirkt beispielsweise die Auslenkung einer Tellerfeder, die das Ein- und Ausrücken der Kupplung steuert.at Activation of the master cylinder becomes the pressure fluid in it transmitted through the hydraulic line to the piston of the central release and thus triggers an axial displacement of the release bearing out. This release bearing consists essentially of a torsionally rigid arranged on a guide sleeve Bearing ring and a rotating with the speed of the clutch bearing shell, between these two components is a common axis of rotation rotating rolling elements are housed. An axial Displacement of the release bearing causes, for example, the Deflection of a diaphragm spring, the engagement and disengagement of the Clutch controls.
Im eingebauten Zustand kann das Ausrücklager einem so genannten Zungenschlag, das heißt, einem Axialschlag der Tellerfederzungen ausgesetzt sein, der den Verschleiß des Ausrücklagers erhöht und damit zu einer Verringerung der Lebensdauer führt. Weiter 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, beispielsweise am Kupplungspedal, auftreten.in the installed condition, the release bearing can be a so-called Tongue strike, that is, an axial stroke of the diaphragm spring tongues be exposed to the wear of the release bearing increases and thus leads to a reduction in the life. Further, the two can be separated by the coupling Drive components an axis-parallel offset of the force-transmitting Have waves caused by a self-centering of the release bearing must be compensated, otherwise the release bearing is exposed to increased wear and loss of comfort due to vibrations, for example on the clutch pedal.
Zur Kompensation bzw. zum Ausgleich eines solchen nachteiligen Zungenschlages und des axialen Versatzes der Kraft übertragenden Wellen werden verschiedene Lösungen aufgezeigt.to Compensation or to compensate for such adverse tongue strike and the axial displacement of the force transmitting waves different solutions are shown.

Diese konstruktive Lösung erfordert jedoch für die zwischen den Tellerfederzungen der Kupplung und dem Außenrücken des Ausrücklagers angeordneten Kugelflächensegmente einen entsprechend verlängerten axialen Bauraum.These However, constructive solution requires for between the diaphragm spring tongues of the clutch and the outer back the release bearing arranged spherical surface segments a correspondingly extended axial space.
Daher besteht die Aufgabe der Erfindung dahin, einen Zentralausrücker mit einer Schlagausgleichseinrichtung zu versehen, wobei der für einen herkömmlichen Zentralausrücker erforderliche axiale Bauraum beibehalten wird.Therefore the object of the invention is to provide a Zentralausrücker to be provided with a shock compensation device, wherein the for a conventional Zentralausrücker required axial space is maintained.
Diese Aufgabe wird mit einem Zentralausrücker mit den Merkmalen des Anspruchs 1 gelöst.These Task is with a Zentralausrücker with the characteristics of claim 1.
Danach ist ein Zentralausrücker, insbesondere zur Betätigung mindestens einer Reibungskupplung in einem Antriebsstrang eines Fahrzeuges zum wahlweisen Trennen und Verbinden zweier Wellen, bestehend aus einem konzentrisch um eine Antriebswelle angeordneten Gehäuse, in dem ein ringförmiger Kolben geführt wird, an dessen einem Ende ein Ausrücklager angeordnet ist, das sich an der Kupplung abstützt, dadurch gekennzeichnet, dass der Kolben in axialer Richtung in zwei Teilkolben aufgeteilt ist und deren Berührungsflächen abwälzend miteinander in Wirkverbindung stehen.After that is a Zentralausrücker, especially for the operation at least one friction clutch in a drive train of a Vehicle for selectively separating and connecting two shafts, consisting from a housing arranged concentrically about a drive shaft, in which an annular piston is guided on whose one end a release bearing is arranged, the is supported on the coupling, characterized that the piston is divided in the axial direction into two part pistons is and their contact surfaces abrolling each other in operative connection.
Zur Realisierung eines reibungsarmen Abwälzvorganges ist in vorteilhafter Ausgestaltung der Erfindung die Berührungsfläche des hinteren Teilkolbens sphärisch und die des vorderen, dem Ausrücklager zugewandten Teilkolbens zu dieser entsprechend kongruent ausgebildet.to Realization of a low-friction rolling process is in Advantageous embodiment of the invention, the contact surface the rear part piston spherical and that of the front, the release bearing facing part piston to this accordingly Congruent trained.
Zur Realisierung eines Schlagausgleiches bzw. Versatzes der Rotationsachse des Ausrücklagers und damit der des vorderen Teilkolbens zur Rotationsachse des hinteren Teilkolbens bzw. der des Zentralausrückers ist es vorteilhaft, die Krümmung der Berührungsflächen der Teilkolben an einen maximal möglichen Schwenkwinkel anzupassen.to Realization of a strike compensation or offset of the rotation axis the release bearing and thus the front part of the piston to the axis of rotation of the rear part of the piston or the central release it is advantageous to the curvature of the contact surfaces the sub-piston to a maximum possible swivel angle adapt.
Weiter ist es vorteilhaft, dass der vordere Teilkolben mit dem Lagerring des Ausrücklagers verbunden ist.Further it is advantageous that the front part piston with the bearing ring the release bearing is connected.
Die Erfindung wird nachfolgend an Hand eines Ausführungsbeispiels und zugehöriger Zeichnungen näher erläutert.The Invention will be described below with reference to an embodiment and associated drawings explained in more detail.
