Abstract

L'invention concerne un dispositif d'embrayage, un module hybride ainsi qu'une chaîne cinématique pour un véhicule automobile. Le dispositif d'embrayage comprend un débrayage (10), au moyen duquel le couple du moteur à combustion peut être transmis au dispositif d'embrayage et au moyen duquel le dispositif d'embrayage est séparable du moteur à combustion ; un élément d'accouplement (43) pour l'accouplement mécanique d'une machine électrique (90) pour la génération d'un couple d'entraînement, et un élément de transmission de couple principal, en particulier un dispositif de double embrayage, au moyen duquel le couple de l'élément d'accouplement de la machine électrique et/ou du débrayage (10) peut être transmis à une chaîne cinématique, le côté sortie de l'élément de transmission de couple principal étant couplé à un arbre (40), en particulier à un arbre creux, et l'arbre (40) formant l'élément d'accouplement (43) pour l'accouplement mécanique d'une machine électrique (90). Le dispositif d'embrayage selon l'invention fournit un dispositif qui combine les avantages d'une machine électrique disposée essentiellement à l'extérieur avec des pertes par friction faibles ainsi qu'un espace de montage axial.
