The invention discloses a transmission assembly, a motor and an electric bicycle, the transmission assembly comprises a crankshaft, a one-way clutch and a pedaling frequency sensor are arranged on the crankshaft, a magnetic ring is arranged on a first outer ring of the one-way clutch, and the first outer ring is connected with the crankshaft, so that the magnetic ring can synchronously rotate with the crankshaft; the magnetic induction device is fixedly installed, the magnetic induction device and the magnetic ring are arranged at an interval, and the magnetic induction device can induce magnetic field changes of the magnetic ring, so that treading frequency and treading direction data of manual treading are collected; the first outer ring is sleeved on the outer side of the crankshaft, the diameter of the first outer ring is larger than that of the crankshaft, and the magnetic ring is mounted on the first outer ring, so that the diameter can be increased, more magnetic poles can be configured on the magnetic ring along the circumferential direction, the number of pole pairs is more, and the accuracy and the resolution of pedaling frequency and pedaling direction data acquisition can be improved; and therefore, the control accuracy of the output rotating speed of the motor is improved.

    本发明公开了一种传动组件、电机和电动自行车,其中传动组件包括曲柄轴,通过在曲柄轴上设置单向离合器和踏频传感器,将磁环设置在单向离合器的第一外环上,第一外环与曲柄轴连接,使磁环能够与曲柄轴同步转动,并将磁感应器件固定安装且与磁环间隔设置,磁感应器件能够感应磁环的磁场变化,从而采集到人力踩踏的踏频踏向数据;由于第一外环套在曲柄轴的外侧,第一外环的直径大于曲柄轴的直径,磁环安装在第一外环上有利于增加直径尺寸,这样可在磁环沿周向配置更多的磁极,极对数更多,有利于提高踏频踏向数据采集的精确度和分辨率,进而提高对于电机输出转速的控制精确,适用于电动自行车。
