Abstract
Description
Die Erfindung betrifft eine Doppelkupplung, insbesondere für ein Getriebe eines Kraftfahrzeuges, vzw. für ein automatisches oder automatisiertes Doppelkupplungsgetriebe, mit zwei Reibkupplungen, wobei die beiden Reibkupplungen einerseits mit einer Motorwelle und andererseits jeweils mit einer Getriebeeingangswelle verbindbar sind, und mit mindestens einem Lamellenträger, wobei der Lamellenträger einen sich im wesentlichen in Axialrichtung erstreckenden Bereich aufweist und der axiale Bereich zur Aufnahme der Lamellen vorgesehen ist.The The invention relates to a double clutch, in particular for a transmission of a motor vehicle, vzw. for an automatic or automated dual-clutch transmission, with two friction clutches, wherein the two friction clutches on the one hand with a motor shaft and on the other hand in each case connectable with a transmission input shaft are, and with at least one plate carrier, wherein the Plate carrier is a substantially in the axial direction extending portion and the axial portion for receiving the slats is provided.
Doppelkupplungen für Doppelkupplungsgetriebe, teilen das zu übertragende Drehmoment auf, nämlich auf zwei verschiedene Getriebeeingangswellen eines Doppelkupplungsgetriebes. Die vzw. mit der ersten Gangstufe der ersten Eingangswelle verbindbare erste Reibkupplung ist im Allgemeinen die thermisch höher belastete Kupplung, da diese den Schlupf während des Anfahrens und die dadurch entstehende Wärme abführen muss. Als Kupplungssysteme bieten sich nasslaufende Reibkupplungen mit einer oder mehreren Lamellen an. Die Anzahl der Lamellen wird jeweils in Abhängigkeit des Anwendungsfalls von Drehmoment und Wärmebelastung ausgewählt.dual clutches for dual-clutch transmissions, divide that to be transmitted Torque on, namely on two different transmission input shafts a dual-clutch transmission. The vzw. with the first gear The first input shaft connectable first friction clutch is generally the thermally higher loaded clutch, since these slip during startup and the resulting heat must pay. The coupling systems are wet-running Friction clutches with one or more blades on. The number of Slats will depend on the application case selected from torque and heat load.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Doppelkupplung derart auszugestalten und weiterzubilden, so dass die Doppelkupplung weniger Bauteile aufweist und einen geringen radialen Bauraum benötigt.Of the Invention is therefore the object of a double clutch such and further develop, so that the double clutch has fewer components and requires a small radial space.
Diese zuvor aufgezeigte Aufgabe wird nun für die Doppelkupplung dadurch gelöst, dass der Lamellenträger drehfest mit der Motorwelle funktional wirksam verbunden oder verbindbar ist und dass der Lamellenträger so ausgebildet und derart angeordnet ist, so dass dem axialen Bereich auf der einen Seite die Lamellen der einen Reibkupplung und auf der anderen Seite die Lamellen der anderen Reibkupplung zugeordnet sind. Die Doppelkupplung weist daher zum einen wenige Bauteile auf und hat zum anderen einen geringen radialen Bauraumbedarf. Da nur noch ein einzelner axialer Bereich vorgesehen ist, dem beide Reibkupplungen zugeordnet sind, wird beim Lösen der einen Reibkupplung und beim Schließen der anderen Reibkupplung der zum Synchronisieren der Drehgeschwindigkeit der beiden Getriebeeingangswellen nötige Kraftfluss nur über den einen axialen Bereich übertragen. Die Kupplungshauptnabe kann in dieser Ausgestaltung von der Drehmomentlast beim gleichzeitigen Schalten der beiden Reibkupplungen entlastet werden. Zudem können durch die radiale Bauraumersparnis größere Lamellen eingesetzt werden, wodurch die Flächenpressung der Lamellenpakete herabgesetzt werden kann. Die eingangs beschriebenen Nachteile sind daher vermieden und entsprechende Vorteile erzielt.These previously indicated task will now for the double clutch solved by the fact that the plate carrier rotatably functionally operatively connected or connectable with the motor shaft is and that the plate carrier is formed and so is arranged so that the axial region on one side of the Slats of a friction clutch and on the other side the slats associated with the other friction clutch. The double clutch points Therefore, on the one hand a few components and on the other hand has a low radial space requirement. Because only a single axial area is provided, the two friction clutches are assigned, when releasing a friction clutch and when closing the other friction clutch for synchronizing the rotational speed of the two transmission input shafts necessary power flow transmitted only over the one axial region. The clutch master hub may in this embodiment of the torque load Relieved at the simultaneous switching of the two friction clutches become. In addition, by the radial space savings larger slats are used, causing the Surface pressure of the disk packs are reduced can. The disadvantages described above are therefore avoided and achieved corresponding benefits.
Es gibt nun eine Vielzahl von Möglichkeiten, die erfindungsgemäße Kupplung in vorteilhafter Art und Weise auszugestalten und weiterzubilden. Hierfür darf zunächst auf die dem Patentanspruch 1 nachgeordneten Ansprüche verwiesen werden. Im Folgenden wird nun eine bevorzugte Ausgestaltung der Erfindung anhand der folgenden Zeichnung und der dazugehörigen Beschreibung näher erläutert. In der Zeichnung zeigt:It Now there are a variety of ways, the invention Design and develop clutch in an advantageous manner.
