Abstract
The present invention relates to a motor vehicle rotary electric machine () drive assembly, the drive assembly comprising a rotor shaft () extending along a longitudinal axis (X) and a connecting piece () providing connection between the shaft and the torque transmission system comprising a bore () for the passage of the rotor shaft, the drive assembly being characterized in that the bore comprises a first wall () extending axially and a cylindrical second wall () extending axially in alignment with the first wall, and in that the rotor shaft comprises: —a first surface () extending axially and cooperating with the first wall of the bore to centre the connecting piece around the rotor shaft; and—a second cylindrical surface () extending axially and provided with knurling, with a diameter (A) greater than the diameter (A') of the second wall of the bore, the connecting piece being force-fitted onto the rotor shaft by means of the knurling.
