Abstract
(DE)
Die Erfindung betrifft eine Drehmomentübertragungseinrichtung, ein Hybridmodul für ein Kraftfahrzeug zum Ankoppeln einer Verbrennungskraftmaschine sowie eine Antriebsanordnung für ein Kraftfahrzeug. Eine Drehmomentübertragungseinrichtung (1) umfasst eine Trennkupplung (10) mit einer Eingangsseite (11) zur mechanischen Kopplung der Trennkupplung (10) mit einer Antriebswelle (3), insbesondere einer Kurbelwelle einer Verbrennungskraftmaschine, und einer Ausgangsseite (12) zur mechanischen Kopplung der Trennkupplung (10) mit einer Abtriebswelle (4), insbesondere mit einer Getriebeeingangswelle, so dass mittels der Trennkupplung (10) Drehmoment von einer Verbrennungskraftmaschine auf ein an die Drehmomentübertragungseinrichtung (1) gekoppeltes Getriebe übertragbar ist und der Drehmoment-Übertragungspfad zwischen Getriebe und Verbrennungskraftmaschine trennbar ist, wobei die Trennkupplung (10) zur axialen Kraftbeaufschlagung von Lamellen (15) der Trennkupplung (10) einen Drucktopf (21) umfasst, dadurch gekennzeichnet, dass der Drucktopf (21) in axialer Richtung der Eingangsseite (11) der Trennkupplung (10) gegenüberliegt. Mit der der hier vorgeschlagenen erfindungsgemäßen Drehmomentübertragungseinrichtung wird bei geringem axialen Bauraumbedarf und langer Lebensdauer ein optimaler Fährbetrieb eines damit ausgestatteten Kraftfahrzeugs gewährleistet.

The invention relates to a torque transmission device, to a hybrid module for a motor vehicle for coupling an internal combustion engine and to a drive arrangement for a motor vehicle. A torque transmission device (1) comprises a disconnect clutch (10) having an input side (11) for mechanically coupling the disconnect clutch (10) to a drive shaft (3), in particular to a crankshaft of an internal combustion engine, and having an output side (12) for mechanically coupling the disconnect clutch (10) to an output shaft (4), in particular to a gearbox input shaft, with the result that the disconnect clutch (10) allows torque to be transmitted from an internal combustion engine to a gearbox coupled to the torque transmission device (1), and the torque transmission path between the gearbox and internal combustion engine can be disconnected, wherein, for the purpose of applying axial force to plates (15) of the disconnect clutch (10), the disconnect clutch (10) comprises a pressure pot (21), characterized in that the pressure pot (21) is situated opposite the disconnect clutch (10) in the axial direction of the input side (11). The torque transmission device according to the invention that is proposed here ensures the provision of an optimal driving operation of a motor vehicle equipped therewith in combination with a small axial installation space requirement and long service life.

L'invention concerne un dispositif de transmission de couple, un module hybride pour un véhicule automobile destiné à accoupler un moteur à combustion interne ainsi qu'un arrangement d'entraînement pour un véhicule automobile. Un dispositif de transmission de couple (1) comprend un embrayage de séparation (10) ayant un côté entrée (11) servant à l'accouplement mécanique de l'embrayage de séparation (10) à un arbre d'entrée (3), notamment un vilebrequin d'un moteur à combustion interne, et un côté sortie (12) servant à l'accouplement mécanique de l'embrayage de séparation (10) à un arbre de sortie (4), notamment à un arbre d'entrée de boîte de vitesses, de sorte qu'un couple peut être transmis au moyen de l'embrayage de séparation (10) d'un moteur à combustion interne à une boîte de vitesses accouplée au dispositif de transmission de couple (1) et que le trajet de transmission du couple entre la boîte de vitesses et le moteur à combustion interne peut être interrompu. L'embrayage de séparation (10) comporte un pot de pression (21) servant à l'application axiale d'une force sur des lamelles (15) de l'embrayage de séparation (10) et l'invention est caractérisée en ce que le pot de pression (21) se trouve à l'opposé du côté entrée (11) de l'embrayage de séparation (10) dans la direction axiale. Le dispositif de transmission de couple selon l'invention permet de garantir un régime de conduite optimal d'un véhicule automobile qui en est équipé, conjointement avec un faible encombrement axial et une longue durée de vie.
