Abstract
A drive unit for a motor vehicle having an electric machine including a rotor mounted so as to be rotatable around an axis A and coupleable, with a driveshaft acting on the vehicle wheels, and a stator having an electric winding whose terminations are connected to a power source by a connection device arranged at a housing opening of the drive unit and guided through this opening. A housing element encloses the rotor and the stator on the radially outer side. To arrange the connection device such that the installation space is optimized, the winding terminations are connected to first contact elements arranged fixed in position at the stator constructed as axial connectors with respect to the electric machine, and constitute stator contacts. These first contact elements are connected to second contact elements constructed to correspond to the first contact elements arranged at a wall area of the drive unit, and constitute wall contacts. The wall contacts are electrically connected to the connection device or form this connection device.
