Claim 0:
1. A drive apparatus for a vehicle having an electric machine including a rotor shaft constructed as a hollow shaft having an internal tooth arrangement, the drive apparatus comprising:
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 a housing for the electric machine,
the gear mechanism drive shaft has a centering seat which is in abutment with an internal circumference of the rotor shaft with a tight clearance fit, the gear mechanism drive shaft subjected to a bending (D) stress during travel operation as a result of radially active operating forces (FR),
the centering seat of the gear mechanism drive shaft arranged without an axial offset with respect to the rotor shaft rotary bearing and in axial alignment relative to the rotor shaft rotary bearing, resulting in reducing the bending (D) stress of the gear mechanism drive shaft.
