Abstract
The invention relates to a drive unit for a powertrain of an electrically drivable motor vehicle, in particular a hybrid motor vehicle, and to a drive assembly. The drive unit (1) comprises a first electric rotary machine (10) and a second electric rotary machine (20) as well as a first shaft (40) and a second shaft (41), wherein the rotor (11) of the first electric rotary machine (10) is rotationally fixed to the first shaft (40) and the rotor (21) of the second electric rotary machine (20) is rotationally fixed to the second shaft (41). The drive unit (1) further comprises a disconnect clutch (50). According to the invention, one of the two electric rotary machines (10, 20) is at least partially arranged radially and axially in an area radially delimited by the respective other electric rotary machine (10, 20). With the aid of the drive unit and the drive assembly according to the invention, it is possible to ensure optimal operation in an inexpensive and particularly space-saving manner.
