Abstract
A force transfer device with an input and an output, a hydrodynamic component, disposed between input and output, comprising at least one pump shell and one turbine shell and a device for bridging the power transfer through the hydrodynamic component, and a device for damping vibrations. The invention further relates to a drive train with such force transfer device and to a process for controlling the operation of a force transfer device in a drive train, comprising a first drive engine and an electrical machine, which can be operated at least as a generator. The invention is characterized in that an actuatable clutch device is disposed between the turbine shell and the output for decoupling the turbine shell from the output, and said clutch device is disposed in parallel with the lockup clutch. During braking operations through the electrical machine the lockup clutch and the turbine clutch are being deactivated.
