The invention discloses a transmission device of a chainless bicycle. The device comprises a bicycle body; the bicycle body is provided with a front wheel, a rear wheel, a bicycle frame used for fixing the front wheel and the rear wheel, a handlebar used for steering and a power transmission device. The power transmission device comprises a middle shaft assembly, ratchet wheels located on the twosides of the axis of the rear wheel of the bicycle and provided with one-way bearings, and a power connecting rod used for transmitting power. The two ratchet wheels are opposite to each other. According to the bicycle transmission device, potential safety hazards and design defects of an existing bicycle are overcome; a chain of a traditional bicycle is replaced with the power connecting rod, invalid acting caused by upper and lower dead points when pedals of a common bicycle do circular motion does not exist, and the power performance can be more effectively played and improved; and the structure is simple, and operation is convenient.

    本发明公开了一种无链自行车的传动装置,包括自行车本体,自行车本体具有前轮、后轮、用于固定前轮和后轮的车架、用于转向的车把手、动力传输装置,所述动力传输装置包括中轴组件、位于自行车后轮轴心两侧的带有单向轴承的棘轮及用于传输动力的动力连杆,且所述的两个棘轮的相反,本发明的自行车传动装置克服现有自行车安全隐患与设计缺陷,通过动力连杆替换传统自行车的链条,没有普通自行车脚踏板做圆周运动时的上下止点所带来的无效做功,能更有效的发挥和提高动力性能,结构简单,操作方便。
