Abstract

La présente invention concerne une bicyclette et une motocyclette dotée d'un nouveau mécanisme de transmission d'énergie, monté sur une roue motrice conventionnelle, permettant de réduire l'énergie d'entraînement de moitié voire plus, et pouvant être utilisé pour économiser l'énergie de bicyclettes, motocyclettes et tricycles. Selon la présente invention, dans une bicyclette conventionnelle, une chaîne annulaire (21) est fixée à un anneau de maintien de chaîne annulaire (21b) installé sur une roue arrière de façon concentrique avec un axe par l'intermédiaire d'un anneau de séparation en quartiers (21c), un pignon (77) s'engrène avec la chaîne annulaire (21) au niveau de la partie interne supérieure de la chaîne, un autre pignon (8) et le pignon (77) relient respectivement le pignon intégré (72) au pignon (76) par une chaîne (8) pour permettre un mouvement synchronisé, les pignons (77, 76) peuvent tourner sur un axe (23) se trouvant sur un cadre (20f), et les pignons (8, 72) peuvent tourner sur l'axe (7). Dans une motocyclette, 1/2 à 1/3 de l'énergie est nécessaire pour se déplacer sur la même distance à la même vitesse, et une économie d'énergie remarquable peut être faite, et, dans une bicyclette, la bicyclette peut se déplacer dans en montée de la même manière que sur le plat.
