Drive unit system for human-powered vehicles, hub for human-powered vehicles, and drive unit for human-powered vehicles

Abstract

To provide a drive unit system for human power-driven vehicles, a hub for human power-driven vehicles, and a drive unit for human power-driven vehicles capable of preferably transmitting power.SOLUTION: A drive unit system includes an input rotation shaft, a first rotation body, a second rotation body, a transmission body, an electric motor that generates electric power with drive power transmitted from the second rotation body, and a first switch mechanism. The first switch mechanism can switch transmitting conditions of the drive power between a first transmitting condition and a second transmitting condition. The first transmitting condition is a condition where, when the first rotation body rotates in a first rotating direction for the purpose of moving a human power-driven vehicle in a first direction, the transmission body can move in a first moving direction. The second transmitting condition is a condition where, when wheels rotate in a first wheels rotating direction for the purpose of moving the human power-driven vehicle in the first direction, the transmission body can move in a second moving direction opposite to the first moving direction.SELECTED DRAWING: Figure 2
