Abstract

Un module moteur-engrenage (1) pour l'entraînement électrique de véhicules, notamment de bicyclettes, comprend un rotor à disque (3) à noyau d'air et un engrenage cycloïdal. Une bride (2) avec alimentation en retour de champ permanent (7) sépare le moteur (3) de l'engrenage, dans le sens axial. Le rotor à disque (3) est relié à un arbre creux (9) et est monté avec celui-ci sur la bride (2). L'engrenage est monté du côté de sortie (22) sur l'arbre creux (9) et sur une partie (23) qui recouvre l'engrenage. On obtient ainsi un module moteur-engrenage de dimensions réduites qui peut être logé dans la zone de l'axe de la roue entraînée ou dans la zone du moyeu d'une telle roue et qui permet de former un palier simple et compact capable d'absorber de manière fiable toutes forces de réaction.
