Drive unit for a drive train of an electrically driveable motor vehicle, and drive assembly and motor vehicle equipped with same

A drive unit for a drivetrain of an electrically drivable motor vehicle, the drive unit comprising:

• a first electric machine having a rotor;
• a second electric machine having a rotor;
• a housing in which the first electric machine and the second electric machine are arranged within;
• an output shaft to which the rotor of the second electric machine is connected for conjoint rotation;
• a disconnect clutch by which the rotor of the first electric machine is connectable to the output shaft for torque transmission;
• power electronics configured to control at least one of the two electric machines, the power electronics being arranged in an electronics housing, wherein the power electronics comprises at least one connecting element with which the electronics housing is mechanically fixed to the housing of the drive unit;
• a flow system configured to implement a flow of a coolant for at least partial cooling of the power electronics;
• and
• a coolant connection of the flow system in the electronics housing.
