ELECTRICAL ROTATING MACHINE COMPRISING AN INTERMEDIATE SLEEVE INTERPOSED BETWEEN THE SHAFT AND THE POLAR WHEELS AND METHOD FOR MAKING THE ROTOR

摘要

The invention concerns an electrical rotating machine rotor (12), in particular for a motor vehicle, comprising a central shaft (14), an annular core (36) coaxial with the shaft (14) and two polar wheels (20, 22) which are axially arranged on either side of the core (36), of the type wherein the shaft (14) includes at least one drive section (57) which is axially force-fitted into a fixing bore (59) of at least one component (58, 36) of the rotor so as to secure in rotation at least one of the two polar wheels (20, 22) of the rotor (12) to the shaft (14), an intermediate sleeve (58) being radially interposed between each polar wheel (20, 22) and the central shaft (14), and on which sleeve is mounted said polar wheel (20, 22). The invention also concerns a method for making such a rotor.
