Abstract

A torque transmission unit which has a first centrifugal mass that can be non-rotatably associated with an internal combustion engine and a second centrifugal mass that is connected downstream of the first mass and can be associated with a transmission. The second centrifugal mass has a rotor of an electric machine for transmitting a torque that can be electrically generated to the second centrifugal mass and a centrifugal force pendulum for reducing torsional vibrations.
