Patent ID: 7665590

Claim:
A clutch unit for a drive train including an engine and a transmission, said clutch unit comprising: at least two sub-units including a first pre-assembled sub-unit positioned on an output shaft of the engine and including a torsional vibration damper, and a second pre-assembled sub-unit on the transmission side of the drive train and including a double clutch, the two sub-units being couplable with each other through an axial plug-in connection which includes intermeshing profiles and counter-profiles with a predetermined circumferential play between the profiles, wherein the profiles and counter-profiles are biased toward each other to minimize free play therebetween and to reduce noise generated during drive train operation, wherein at least individual profiles that form the profiles and counter-profiles are formed of partial profiles that are supported against each other in opposite directions, at least one holding element for holding the profiles in an angular position against a biasing force acting on them, which holding element enables axially fitting together the profiles and counter-profiles that form the axial plug-in connection, so that when the profiles and counter-profiles are axially brought together axial movement of the holding element enables at least partial circumferential biasing of the plug-in connection.
