Abstract
Description
Die Erfindung betrifft ein Ausrücksystem für eine Doppelkupplung mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The invention relates to a release system for a Double clutch with the features of the preamble of the claim 1.
Eine Doppelkupplung umfasst im Wesentlichen zwei separate Kupplungseinheiten, die unabhängig voneinander über jeweils eine zugeordnete Ausrückvorrichtung eine Verbindung zu einer Getriebeeingangswelle unterbrechen und herstellen können. Ein bevorzugtes Einsatzgebiet einer solchen Doppelkupplung ist die Verwendung mit einem Doppelkupplungsgetriebe. Die erste Kupplungseinheit bedient hierbei üblicherweise die ungeraden Gangstufen und die zweite Kupplungseinheit die geraden Gangstufen. Auf diese Weise kann, während über die eine Kupplungseinheit aktuell das Drehmoment vom Motor auf das Getriebe übertragen wird, bereits eine andere Gangstufe vorgewählt werden, um anschließend ohne Unterbrechung der Zugkraft von der aktuellen Gangstufe in die vorgewählte Gangstufe schalten zu können. Die Getriebeeingangswelle ist hierfür vorzugsweise aus zwei konzentrischen Wellen zusammengesetzt, das heißt aus einer Hohlwelle mit einer innen liegenden Vollwelle.A Dual clutch essentially comprises two separate clutch units, independently of each other via an associated release device interrupt a connection to a transmission input shaft and can produce. A preferred application of a such dual clutch is the use with a dual clutch transmission. The first coupling unit usually operates here the odd gear ratios and the second clutch unit the even gears. In this way, while on the one clutch unit currently transmit the torque from the engine to the transmission is already being selected a different gear, then without interruption of the traction of the shift the current gear to the preselected gear to be able to. The transmission input shaft is preferred for this purpose composed of two concentric waves, that is from a hollow shaft with an inside solid shaft.

Allerdings führt die Fixierung des Nehmerzylinderkolbens über einen außerhalb der Mantelfläche des Ausrücksystems angebrachten Hebelarm zu einer radialen Bauraumvergrößerung des Ausrücksystems.Indeed leads to the fixation of the slave cylinder piston one outside the lateral surface of the release system attached lever arm to a radial space enlargement of the release system.
Aufgabe der Erfindung ist es daher, ein Ausrücksystem für eine Doppelkupplung mit einer Verdrehsicherung für beide Nehmerzylinderkolben gegenüber ihrem gemeinsamen Gehäuse zu schaffen, ohne den für das Ausrücksystem erforderlichen radialen Bauraum zu vergrößern. Diese Aufgabe wird mit einem Ausrücksystem für eine Doppelkupplung mit den Merkmalen des Anspruchs 1 gelöst.task The invention is therefore a release system for a double clutch with an anti-rotation lock for both Slave cylinder pistons relative to their common housing without the necessary for the release system increase radial space. This task comes with a release system for a double clutch solved with the features of claim 1.
Danach besteht das Ausrücksystem für eine Doppelkupplung aus einem mehrere Gehäusewände aufweisenden, kreisringförmigen Nehmerzylindergehäuse, wobei konzentrisch zu seiner Symmetrieachse zwischen der inneren Gehäusewand und der mittleren Gehäusewand ein erster kreisringförmiger Nehmerzylinderkolben und zwischen mittlerer Gehäusewand und äußerer Gehäusewand ein zweiter kreisringförmiger Nehmerzylinderkolben axial verschiebbar angeordnet ist. Der zweite Nehmerzylinderkolben wird durch eine an der Mantelfläche des Nehmerzylindergehäuses angeordnete Verdrehsicherung an seiner Drehbewegung gehindert. Um zu gewährleisten, dass beide Nehmerzylinderkolben an ihrer Drehbewegung gehindert werden, ist unter Beachtung der Minimierung des Platzbedarfs an jedem Nehmerzylinderkolben mindestens ein radial zur Symmetrieachse hin gerichtetes Anschlagselement vorgesehen, das mit mindestens einer Aussparung in der jeweiligen Gehäusewand in Wirkverbindung steht.After that the release system consists of a double clutch from a plurality of housing walls having, annular Slave cylinder housing, concentric with its axis of symmetry between the inner housing wall and the middle housing wall a first annular slave cylinder piston and between middle housing wall and outer housing wall a second annular slave cylinder piston axially slidably arranged. The second slave cylinder piston becomes by a on the lateral surface of the slave cylinder housing arranged rotation prevented from its rotational movement. Around to ensure that both slave cylinder pistons on their Rotational movement are hindered, taking into account the minimization the space requirement on each slave cylinder piston at least one radial provided to the symmetry axis directed towards stop element, that with at least one recess in the respective housing wall is in active connection.
In vorteilhafter Weiterbildung der Erfindung besitzt jeder Nehmerzylinderkolben mehrere eine Breite und Höhe aufweisende Anschlagsegmente, die am Umfang jedes Nehmerzylinderkolbens zueinander beabstandet angeordnet sind.In Advantageous development of the invention has each slave cylinder piston a plurality of width and height having stop segments, the arranged on the circumference of each slave cylinder piston spaced from each other are.
Weiter ist es vorteilhaft, dass in der inneren Gehäusewand und in der mittleren Gehäusewand mehrere, eine Breite und eine Höhe aufweisende, zueinander beabstandete Aussparungen vorgesehen sind, so dass die zur Symmetrieachse hin gerichteten Anschlagsegmente der Nehmerzylinderkolben in den Aussparungen der Gehäusewände geführt werden können.Further It is advantageous that in the inner housing wall and in the middle housing wall several, one width and one Are provided with height, spaced-apart recesses, such that the stopper segments directed towards the symmetry axis the slave cylinder piston in the recesses of the housing walls can be performed.
Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, dass die Höhe der Aussparungen in den Gehäusewänden mindestens der Länge der Ausrückwege der Nehmerzylinderkolben entspricht.A further advantageous embodiment of the invention provides that the height of the recesses in the housing walls at least the length of Ausrückwege the slave cylinder piston corresponds.
In vorteilhafter Weise ist die Breite der Anschlagsegmente an die Breite der Aussparungen in den Gehäusewänden angepasst.In Advantageously, the width of the stopper segments to the width adapted to the recesses in the housing walls.
Die Erfindung wird nachfolgend anhand 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.
