The invention relates to a pull (lever) rod bicycle, which adopts a pull rod driven bicycle and abandons a chain transmission system, so that the technical defects that a transmission chain is easy to damage and break, labor and labor are wasted and maintenance is inconvenient in the existing bicycle technology are overcome. The bicycle mainly comprises a handlebar, a frame, a saddle, a front wheel assembly, a rear wheel assembly and a transmission system. The transmission system is composed of a lever pedal, a pull rod and a driving disc. The lever pedal is used for treading and providing power; the pull rod is connected with the lever pedal and the driving disc for transmitting power; the driving disc is fixed outside the rear wheel frame, integrated with the rear wheel and used for receiving power to drive the rear wheel. Due to the fact that pull rod transmission is adopted in the transmission technology, a transmission system is smoother and more portable, and the technical problem of chain transmission is solved. The transmission technology has the advantages of being long in arm of force, large in torque, capable of saving labor and increasing efficiency, simple and firm, and therefore riding is more light, flexible and convenient, and the effect of getting twofold results with half the effort is achieved.
一种拉(杠)杆自行车,采用拉杆驱动的自车,摈弃了链条传动系统,从而解决了现有自行车技术存在的传动链条易损坏断裂、费工费力,养护不便的技术缺陷。它主要包括车把、车架、车座、前轮总成、后轮总成和传动系统。传动系统由杠杆踏板、拉杆、驱动盘组成。杠杆踏板用于踩踏,提供动力;拉杆连接杠杆踏板和驱动盘,用于传递动力;驱动盘固定于后轮车架外,与后轮一体,用于接受动力驱动后轮。本传动技术由于采用拉杆传动,使得传动系统更加顺畅轻便,消除了链条传动的技术问题。本传动技术具有力臂长,扭矩大,省力增效,简单坚固的特点,从而使骑行更加轻巧灵便,事半功倍的效果。
