Gear clutch output shaft applied to motor, middle motor and electric bicycle

The utility model provides a gear clutch output shaft applied to a motor, a middle motor and an electric bicycle. The gear clutch output shaft comprises an output shaft, a gear and a clutch mechanism, the gear, the clutch mechanism and the output shaft are coaxially arranged; the clutch mechanism is located between the output shaft and the gear, and the clutch mechanism limits the output shaft and the gear. The clutch mechanism is rotationally connected with the output shaft and the gear. According to the utility model, the output shaft, the gear and the clutch mechanism are combined together, so that when the electric bicycle with the built-in motor system is powered off for riding, manpower cannot drive the gear to rotate, gear damping cannot be generated to consume energy, and the noise of the gear is reduced. 本实用新型提供了一种应用于电机的齿轮离合器输出轴、中置电机及电动自行车，包括输出轴、齿轮、离合器机构；所述齿轮、离合器机构和输出轴同轴设置；所述离合器机构位于输出轴和齿轮之间，且离合器机构对输出轴和齿轮进行限位；所述离合器机构分别转动连接输出轴和齿轮。本实用新型输出轴、齿轮和离合器机构组合在一起，使中置电机系统的电动自行车断电骑行时，人力不会带动齿轮转动，不会产生齿轮阻尼消耗能量，降低了齿轮噪音
