Abstract

Le groupe motopropulseur (31) pour véhicule automobile (30) électrique ou hybride, comprend une machine électrique tournante (32) fixée à un dispositif différentiel (3), la machine électrique comprenant un rotor (18) supporté en rotation par des roulements (34, 35) maintenus en butée par le rotor et un carter (33) de la machine électrique, le dispositif différentiel comprenant un arbre primaire creux (6) comportant un cylindre étanche (9) formé par la surface périphérique intérieure de l’arbre primaire creux et par un bouchon étanche (11) disposé dans l’arbre primaire creux, le rotor comportant un arbre rotorique (19) plein inséré dans le cylindre de manière à former une chambre de compression (23). Les roulements sont en contact avec le carter et le rotor, un effort axial de précontrainte (FA) induit sur l’arbre rotorique par la pression régnant dans la chambre de compression étant configuré pour précontraindre les roulements. Figure pour l’abrégé : Fig 3The powertrain (31) for an electric or hybrid motor vehicle (30) comprises a rotating electric machine (32) fixed to a differential device (3), the electric machine comprising a rotor (18) supported in rotation by bearings (34 , 35) held in abutment by the rotor and a casing (33) of the electric machine, the differential device comprising a hollow primary shaft (6) comprising a sealed cylinder (9) formed by the inner peripheral surface of the hollow primary shaft and by a sealed plug (11) disposed in the hollow primary shaft, the rotor comprising a solid rotor shaft (19) inserted into the cylinder so as to form a compression chamber (23). The bearings are in contact with the housing and the rotor, an axial pre-stressing force (FA) induced on the rotor shaft by the pressure prevailing in the compression chamber being configured to pre-stress the bearings.
