The axes of rotation of the rotor shafts and the main axis of the gear are aligned coaxially with each other. The motors and gearbox are housed in a common housing. The transmission is formed at least of a differential and a torque vectoring unit. The differential is drivable with the main motor and the torque vectoring unit connected between the differential and the servomotor is drivably operatively connected to the servomotor. The common placement of the individual modules in a housing allows a compact and independent drive unit.
  • The term torque vectoring unit stands for a transmission, preferably for a planetary gear, are introduced via the power applied by the servomotor in addition to the main drive in the differential torques. As a result, the torque distribution which is inherently natural to a differential is selectively influenced and superimposed on the drive shafts.
  • The drive unit can be mounted easily if, as an embodiment of the invention provides, at least the differential is an independent of the housing in self-holding preassembled unit that can be used in the housing or in a housing part. With such a design, the number of parts at the location of the final assembly of the drive unit is reduced. As an alternative to this embodiment of the invention, or in combination with this embodiment, it is provided that the torque vectoring unit is a preassembled unit that is self-contained independently of the housing.
  • A further embodiment of the invention provides that the drive unit has a housing formed from at least three housing parts, in which preferably the main motor, the gearbox and the servo motor are each housed in another of the housing parts.
  • The above and below described elements of the invention make it possible to assemble drive units according to the modular principle, which are adapted to different requirements. The plurality of parts can be reduced by the choice of common parts and / or by the optional combination of pre-assembled modules.
