L'invention concerne un système de moyeu électrique à vitesse réglable et un véhicule électrique comprenant un mécanisme de moyen et un moteur d'entraînement (1) inséré dans le moyeu de roue et disposé sur l'arbre de support central du moyeu, l'arbre de sortie du moteur d'entraînement (1) étant disposé perpendiculaire par rapport à l'arbre central du moyeu. Un premier engrenage conique (2) est relié à l'arbre de sortie du moteur d'entraînement (1) qui l'entraîne, un second engrenage conique (3) est en prise et connecté au premier engrenage conique (2) et peut changer la direction de 90 ° du premier engrenage conique (1) en transmettant la puissance de sortie du moteur d'entraînement (1). Un premier engrenage (5) est relié à et connecté par le second engrenage conique (3) alors qu'un second engrenage cylindrique (6), disposé sur un côté du moyeu, est en prise avec le premier engrenage (5) et entraîne le moyeu pour faire tourner l'arbre de support central du moyeu.
