  • Electric motor-driven motor-vehicle vacuum pump, and drive shaft for a motor vehicle vacuum pump
    Patent number: 10288067
    Abstract: The invention relates to an electric motor-driven motor-vehicle vacuum pump (1), having a drive shaft (3) which has, in particular, two bearings and extends with a shaft stub (5; 35; 45) into a rotor (8) which is connected fixedly to the shaft stub so as to rotate with it. In the rotor, the shaft stub has a centring region (26; 36; 46) which serves to center the rotor, without guiding the rotor in the axial direction.
