Abstract
A drive unit for a drivetrain of a hybrid motor vehicle comprises a first electric machine and a second electric machine, which, in respect of its rotor, is arranged coaxially with an axis of rotation of a rotor of the first electric machine. A first transmission stage is arranged between a drive component, which is configured to be selectively coupled for conjoint rotation to an output shaft of an internal combustion engine, and a power shaft of the first electric machine and/or of the second electric machine. A transmission component unit is provided, via which the power shaft of the respective electric machine is configured to be selectively coupled to wheel driveshafts. The drive component of the internal combustion engine is coupled to an intermediate gear unit via a second transmission stage. The intermediate gear unit has an integrated clutch and is further connected to the wheel driveshafts in such a way that, depending on the position of the integrated clutch, the internal combustion engine is coupled to the wheel driveshafts via at least the second transmission stage or is decoupled from the wheel driveshafts.
