Abstract

L'invention concerne un appareil pour réapprovisionner en énergie une batterie à volant lorsqu'une bicyclette descend une pente. La bicyclette comporte un dispositif d'accouplement et de désolidarisation manuel et un ensemble de puissance motrice (2), le dispositif d'accouplement et de désolidarisation manuel commandant le réapprovisionnement ou non en énergie d'une batterie à volant (3) selon l'état de déplacement de la bicyclette. L'ensemble de puissance motrice reçoit la force d'entraînement d'une roue arrière de bicyclette (72) et réapprovisionne en énergie la batterie à volant. L'avantage est que, en l'absence de source d'alimentation, la bicyclette peut être utilisée pour réapprovisionner en énergie cinétique la batterie à volant. La commande manuelle du moment de réapprovisionnement en énergie de la batterie à volant allège la charge de force humaine. Ainsi, lorsque la bicyclette descend une pente, l'appareil se couple à la bicyclette pour fournir de l'énergie cinétique au volant (31). Lorsque la bicyclette gravit une pente ou se déplace à plat, l'appareil se sépare de la bicyclette pour alléger la charge de force humaine. L'utilisation du principe de force centrifuge signifie qu'après l'arrêt de l'entraînement, un mécanisme d'entraînement peut automatiquement se séparer du volant pour empêcher une déperdition inutile d'énergie provenant du volant.
