A driving mechanism for an electric bicycle is provided with a one-way gear and a driving machine, the output end of the driving machine is sleeved with a transmission shaft tooth a, the one-way gear is connected with the transmission shaft tooth a through a transmission shaft tooth b, a driving crank is in spline connection with the one-way gear, the number of parts is small, the structure is simple, cost is low, the overall structure is compact, and noise caused by loosening of the parts is avoided; according to the structure, the driving machine directly transmits force to the driving crank, the torque main shaft is not needed, output loss is avoided, the torque main shaft is only used as a connecting rod, mechanical constraint is reduced, and more labor is saved when a main foot end is treaded; the transmission shaft tooth b realizes secondary transmission, and the pressure of the driving machine acting on the driving crank is reduced; chain transmission is not used, so that energy loss caused by chain transmission is reduced, and the maintenance problems caused by chain blockage, chain lifting and the like can be reduced; the original fluted disc mounting mode is not changed during use, mounting, maintenance and replacement are convenient and fast, and the replacement cost is low.

    一种电动自行车用驱动机构,设置有单向齿轮、驱动机,并在驱动机的输出端套装有传动轴齿a,单向齿轮通过传动轴齿b与传动轴齿a连接,将主动曲柄与单向齿轮花键连接,零件少,结构简单,成本低,整体结构紧凑,避免零部件松动出现噪音,此种结构为驱动机直接将力传输给主动曲柄,无需经过力矩主轴,避免输出损耗,力矩主轴只作为连接杆使用,减少了机械束缚,踩踏主脚端时更省力;传动轴齿b实现二级传动,减小驱动机作用在主动曲柄上的压力;且不使用链条传动,减少由于链条传动造成的能量损耗,也能减少由于链条卡顿、吊链等出现的维修问题;使用时不更改原有齿盘安装方式,安装、维修更换时方便、快捷,且更换成本少。
