Patent ID: 8235191

Claim:
A multifunctional unit for application in drive trains ( 41 ) with hybrid drive, comprising: at least one electrical machine (EM), operable as a generator; at least one input ( 2 ) and one output ( 3 ); a hydrodynamic component ( 4 ) disposed between input ( 2 ) and output ( 3 ), comprising at least one pump shell (P) and one turbine shell (T); force transfer device, comprising: ( 1 ); and a device ( 7 , 8 ) for bridging the power transfer through the hydrodynamic component ( 4 ) and a device ( 14 ) for damping vibrations, wherein: the force transfer device ( 1 ) comprises an actuatable clutch device ( 10 ) for decoupling the turbine shell (T) from the output ( 3 ), disposed, viewed in the direction of the force flow, between input ( 2 ) and output ( 3 ), in series with the turbine shell (T) and in parallel with the device ( 7 , 8 ) for bridging the power transfer through the hydrodynamic component ( 4 ); the device ( 14 ) for damping vibrations and the device ( 7 , 8 ) for bridging the power transfer through the hydrodynamic component ( 4 ) are disposed in series; when the actuatable clutch device is closed a first torque path is formed from the input to the output, the first torque path bypassing both the device for bridging the power transfer and the device for dampening vibrations; and when the device for bridging the power transfer is closed a second torque path, different from the first torque path, is formed from the input to the output, the second torque path bypassing the actuatable clutch device.
