The invention provides a power-assisted bicycle capable of being treaded vertically. The bicycle comprises a bicycle frame and wheels. A connecting shaft I is arranged on the bicycle frame, and an upper chain wheel I and an upper chain wheel II are arranged on the connecting shaft I; a connecting shaft II is arranged on the bicycle frame; a lower chain wheel I and a lower chain wheel II are arranged on the connecting shaft II; a transmission chain I is connected between the upper chain wheel I and the lower chain wheel I; a transmission chain II is connected between the upper chain wheel II and the lower chain wheel II; a driving wheel is arranged on the connecting shaft II; a ratchet mechanism I is arranged between the lower chain wheel I and the connecting shaft II; a ratchet mechanism II is arranged between the lower chain wheel II and the connecting shaft II; and a pedal I and a pedal II are arranged on the bicycle frame. A problem of acting force dead points is solved in a vertical treading mode, and the bicycle is constant in transmission efficiency, reasonable in force application, labor-saving in riding, high in efficiency and so on. An efficient inclined double-roller wormand gear transmission mechanism can be additionally arranged on the bicycle so that the bicycle can be driven by a high-rotating-speed working motor, and has the advantages of a small size, high efficiency, power saving, assistance and the like.

    本发明提供了一种上下直立踩踏的助力自行车,包括车架以及车轮,车架上设置有连接轴一,连接轴一上设有上链轮一以及上链轮二;车架上设有连接轴二,连接轴二上设置有下链轮一以及下链轮二;上链轮一与下链轮一之间连接有传动链一,上链轮二与下链轮二之间连接有传动链二;连接轴二上设置有驱动轮;下链轮一与连接轴二之间设置有棘轮机构一,下链轮二与连接轴二之间设置有棘轮机构二;车架上设有踏板一以及踏板二。通过直立踩踏的方式解决作用力死点的问题,具有传动效率恒定、施力合理、骑行省力、效率高等优点。自行车上可加装高效的倾斜式双滚子蜗轮蜗杆传动机构,如此可用以高转速工作电机用以驱动,具有体积小、效率高、省电、助力等优点。
