Abstract

A hybrid module is for a motor vehicle and is configured for coupling an internal combustion engine. The hybrid module includes a connection device ( 10 ) for the mechanical coupling of an internal combustion engine; a separating clutch ( 30 ), by which torque can be transmitted from the internal combustion engine to the hybrid module ( 1 ); an electric motor ( 40 ) for producing a drive torque having a hollow-cylindrical rotor ( 42 ); a dual clutch device ( 50 ), by which torque can be transmitted from the electric motor ( 40 ) and/or from the separating clutch ( 30 ) to a drive train, having a first component clutch ( 60 ) and a second component clutch ( 70 ); a separating clutch actuation system ( 35 ) for actuating the separating clutch ( 30 ); a first actuation system ( 61 ) for actuating the first component clutch ( 60 ) and a second actuation system ( 71 ) for actuating the second component clutch ( 70 ), wherein the connection device ( 10 ), the separating clutch ( 30 ) and the first component clutch ( 60 ) and/or the second component clutch ( 70 ) are arranged substantially in series along an arrangement direction ( 2 ), and at least a section of at least one of the clutches, namely the separating clutch ( 30 ), the first component clutch ( 60 ) and the second component clutch ( 70 ), is arranged within the space ( 43 ) enclosed by the rotor ( 42 ). Along the arrangement direction ( 2 ), the separating clutch actuation system ( 35 ) and the first actuation system ( 61 ) are arranged on the side of the electric motor ( 40 ) which faces the connection device ( 2 ).
