Abstract
A drive unit for a drive train of an electrically drivable motor vehicle, in particular a hybrid motor vehicle, and to a drive assembly. The drive unit is for a drive train of an electrically drivable motor vehicle, and includes a first electric rotary machine for generator operation and a second electric rotary machine for drive motor operation, and a transmission. A rotor of the first electric rotary machine is for direct mechanical coupling to an output element of an internal combustion engine, and a rotor of the second electric rotary machine is or can be rotationally coupled to an input of the transmission, with no torque-transmitting connection being provided between the first electric rotary machine and the transmission.
Claims19
A drive unit for a drive train of an electrically drivable motor vehicle, the drive unit comprising:
- a first electric rotary machine adapted for generator operation;
