Abstract
Description
Die Erfindung betrifft ein Kupplungsausrücksystem für eine aus zwei Teilkupplungen bestehende Doppelkupplung eines Fahrzeuges gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a clutch release system for a two-clutch double clutch of a vehicle according to the preamble of claim 1.
Aus
dem Stand der Technik ist mit der
Eine Doppelkupplung dagegen umfasst zwei im Wesentlichen separate Kupplungsmodule bzw. Kupplungseinheiten, die unabhängig voneinander die Drehmomentverbindung zwischen einem Motor und einem Getriebe unterbrechen bzw. herstellen können. Ein bevorzugtes Einsatzgebiet einer solchen Doppelkupplung ist die Kombination mit einem Doppelkupplungsgetriebe. Die erste Kupplungseinheit bedient hierbei beispielsweise die ungeraden Gangstufen, während die zweite Kupplungseinheit die geraden Gangstufen bedient. Auf diese Weise kann, während über die eine Kupplungseinheit aktuell ein 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 meist aus zwei konzentrischen Wellen aufgebaut, das heißt, aus einer Hohlwelle und einer innenliegenden Vollwelle. Die Betätigung der Kupplungseinheiten erfolgt jeweils durch eine Ausrückvorrichtung. Die Betätigung der Ausrückvorrichtungen erfolgt mittels Kolben, wobei einer innenliegend bzw. zentral und der andere Kolben außen bzw. außenliegend angeordnet ist.A Double clutch on the other hand comprises two essentially separate clutch modules or coupling units that independently of each other Interrupt torque connection between a motor and a transmission or can produce. A preferred application of a such dual clutch is the combination with a dual-clutch transmission. The first coupling unit serves, for example, the odd number Gear stages, while the second clutch unit, the straight Gear steps operated. This way, while over the one clutch unit currently has a torque from the engine on the Gear is transmitted, already another gear be preselected, and then without interruption the tractive power from the current gear to the preselected gear to be able to switch. The transmission input shaft is for this mostly composed of two concentric waves, that is, from a hollow shaft and an internal solid shaft. The operation The coupling units takes place in each case by a release device. The actuation of the release devices takes place by means of pistons, one inside or central and the other Piston is arranged outside or outside.
Die Wegmessung bei dieser konventionellen Anwendung erfolgt dabei ebenfalls meist berührungslos durch induktive Sensoren oder Hall-Sensoren, die an dem CSC-Gehäuse angebracht sind und die Bewegung der betätigten Kolben sensieren.The Distance measurement in this conventional application also takes place mostly contact-free by inductive sensors or Hall sensors, which are attached to the CSC housing and the movement sense the actuated piston.
Aus Bauraumgründen, in radialer und axialer Richtung, ist es in den meisten Fällen nicht möglich, einen Sensor für den inneren Kolben zu platzieren.Out Space reasons, in the radial and axial direction, it is in most cases not possible, a sensor to place for the inner piston.
Daher besteht die Aufgabe der Erfindung darin, ein Kupplungsausrücksystem für eine Doppelkupplung zu schaffen, mit dem in einem axial begrenzten Bauraum die Wegmessung des inneren Kolbens möglich ist.Therefore the object of the invention is a clutch release system to create a double clutch, with which in an axial limited space the displacement measurement of the inner piston possible is.
Diese Aufgabe wird mit einem Kupplungsausrücksystem für eine Doppelkupplung mit den Merkmalen des Anspruchs 1 gelöst.These Task is with a clutch release system for a double clutch with the features of claim 1 solved.
Bei einem Kupplungsausrücksystem für eine aus zwei Teilkupplungen bestehende Doppelkupplung eines Fahrzeuges, wobei jeder Teilkupplung ein in einem gemeinsamen Gehäuse angeordneter und geführter ringförmiger Kolben zugeordnet ist, weist die Mantelfläche mindestens einer der Kolben mindestens einen rechtwinklig zur Betätigungsrichtung angeordneten Referenzgeber auf, dessen Länge aus der Mantelfläche des Gehäuse herausragt. Dementsprechend sind im Gehäuse im Bereich des/der Referenzgebers(r) an die Länge des Kolbenausrückweges angepasste Ausnehmungen vorgesehen. Diese Ausnehmungen sind vorteilhafter Weise als Langlöcher ausgebildet.at a clutch release system for one of two Part clutches existing double clutch of a vehicle, wherein each sub-clutch arranged in a common housing and guided annular piston is associated, has the lateral surface of at least one of the pistons at least arranged at right angles to the direction of actuation Referenced on whose length from the lateral surface protrudes from the housing. Accordingly, in the housing in the area of the reference encoder (s) to the length of the Kolbenausrückweges adapted recesses provided. These recesses are more advantageous Way trained as slots.
In einer vorteilhaften Ausgestaltung der Erfindung weist der Referenzgeber die Form eines Stiftes aufweist.In an advantageous embodiment of the invention, the reference encoder has the shape of a pin.
Zur Gewährleistung eines axialen Ausrückweges beider Kolben sind diese zueinander verdrehgesichert sind.to Ensuring an axial Ausrückweges both Piston these are mutually against rotation.
Zur Sensierung der jeweiligen Position der Kolben bzw. mindestens eines Kolbens steht vorteilhafter Weise der entsprechende Referenzgeber mit einem diesem zugeordneten Sensor in Wirkverbindung.to Sensing the respective position of the piston or at least one Piston is advantageously the corresponding reference encoder with an associated sensor in operative connection.
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.
