is adjoined by a housing cover 31 which contains the offset drive 15 this offset drive 15 comprises a primary gear wheel 32 which can be driven by the second rotor 28 via the third clutch 14 and a secondary gear wheel 36 which is driven in this case via a toothed chain 35 instead of the toothed chain other traction mechanisms or intermediate gear wheels could also be provided bearings 33 34 are provided on both sides of the primary gear wheel 32 the secondary gear wheel 37 is guided in bearings 37 and is connected to a flange 38 such that it is fixed against rotation to which flange 38 the propeller shaft 16 is connected an output drive flange 39 which is adjoined by the second clutch 5 fig1 is also provided coaxially with the primary gear wheel 32 with reference to fig3 the content of the two modules 10 12 will now be described in more detail the first shaft 40 which is driven via the oscillation damper 2 is mounted firstly by means of a bearing 41 in the wall 22 of the housing it is connected to an inner part 42 of the first clutch 3 such that it is fixed against rotation its outer part 43 is connected to a coupling piece 45 such that it is fixed against rotation which coupling piece 45 contains a needle bearing 62 in which the other end of the first shaft 40 is mounted a coupling disk 46 is likewise connected in this case welded to the coupling piece 45 such that it is fixed against rotation the outer part.
