Abstract

A drive unit and a drive arrangement having the drive unit are provided. The drive unit includes a first electric machine and a second electric machine and an output shaft. A rotor of the second electric machine is connected to the output shaft for conjoint rotation and the drive unit has a separating clutch by which a rotor of the first electric machine is connected to the output shaft for torque transmission. The drive unit furthermore has a first flow system for implementing a flow of a first liquid for at least partial cooling of at least one electric machine and a second flow system for implementing a flow of a second liquid, the first flow system and the second flow system being arranged such that heat from the first liquid in the first flow system is transferred to the second liquid in the second flow system.
