A traditional bicycle is driven by a chain to move forwards through circular motion of a pedal crank mechanism. A traditional pedal crank mechanism and the force exerting direction of a rider have theproblem of motion dead points. Therefore, the mechanical efficiency is not high when a person rides the bicycle, large physical waste is caused, therefore, the riding distance of the bicycle is limited, and green travel development is not facilitated. According to the novel high-efficiency bicycle driving device provided by the invention, the mechanical efficiency of a traditional bicycle can beimproved by more than 20%, the structure is simple and durable, the manufacturing cost is not high, the device is particularly suitable for operation of shared bicycles, the convenient traffic range of traffic networks such as the shared bicycles and subways can be greatly expanded, and development and expansion of urban green travel network construction are facilitated.

    传统自行车都是以脚踏曲柄机构做圆周运动通过链条驱动前行,由于传统的脚踏曲柄机构与骑行人的发力方向存在运动死点问题,所以人在骑行自行车时机械效率并不高,造成体力浪费较大,也就限制了自行车的骑行距离,不利于更大的发展绿色出行,本发明就是提供一种新型高效率自行车驱动装置,能够将传统自行车的机械效率提高20%多,并且结构简单耐用造价也不高,尤其适合共享单车的运行,能够更大地拓展共享单车与地铁等交通网络的便利交通范围,有利于发展扩大城市的绿色出行网络建设。
