Abstract: A drive apparatus for a vehicle having an electric machine whose rotor shaft is constructed as a hollow shaft having an internal tooth arrangement. A gear mechanism drive shaft, which has an external tooth arrangement, is inserted coaxially relative to the hollow shaft into the hollow shaft, to form a torque-transmitting spline. The rotor shaft with a rotor shaft rotary bearing being interposed is guided outward through a bearing opening of an electric machine housing, and the gear mechanism drive shaft has a centering seat which is in abutment with the internal circumference of the rotor shaft with a tight clearance fit. The gear mechanism drive shaft is subjected to bending (D) during travel operation as a result of radially active operating forces (FR). To reduce the bending stress (D), the centering seat of the gear mechanism drive shaft is arranged without an axial offset with respect to the rotor shaft rotary bearing, in axial alignment relative to the rotor shaft rotary bearing.
