Abstract

La présente invention a trait à un ensemble moteur moyeu électrique à essieu amovible. Des véhicules à une, deux ou plus de deux roues tels que des motos, des scooters et des pousse-pousse sont beaucoup utilisés dans les villes où les routes sont encombrées et polluent l'atmosphère avec des vapeurs d'essence ou de diesel. Afin de lutter contre cette pollution, l'utilisation de véhicules à énergie électrique est proposée. Pour ces véhicules à énergie électrique, des moteurs moyeux actionnés par batterie sont utilisés. Ils sont montés à l'intérieur du moyeu de la roue mais il est difficile de retirer la roue du châssis de véhicule lorsqu'il est nécessaire de réaliser des opérations d'entretien. La présente invention concerne un ensemble moteur moyeu qui permet le démontage et le remontage de la roue de/sur la fourchette du véhicule avec facilité.
