A hybrid drive unit for installation between an internal combustion engine and a vehicle transmission in a motor vehicle. The hybrid drive unit has an electric machine operable, alternatively, as a motor and a generator and having at least one stator and one rotor, the rotor having bearings on a transmission side and on an internal combustion engine side. One set of bearings is provided on the transmission side and, on the internal combustion engine side, the hybrid drive unit is supported on the crankshaft bearings of the internal combustion engine. A non-rotary connection can be established, for example, by means of a flexplate or a torsional vibration damper, between the rotor of the electric machine and the crankshaft of the internal combustion engine. Before the rotor is connected to the crankshaft, the rotor is supported on bearings on the transmission side. A radial safety mechanism is provided on the internal combustion engine side in order to prevent the rotor from tilting around the bearing on the transmission side and from establishing contact with the stator. When the rotor and the crankshaft are not connected to each other, the radial safety mechanism prevents contact between the rotor and the stator, and thus destruction of the electric machine.
