一种新型无链条自行车
摘要：
一种新型无链条自行车，它涉及一种自行车的改进，传动轴(5)的前端设有锥齿轮(5-1)，传动轴的后端设有锥齿轮(5-2)，踏板复位装置(10)的中部通过固定装置(11)固定在横梁(9)的前端、前轮(2)的后方，两个踏板(6)的前端分别固定在踏板复位装置(10)的两端；主动锥齿轮8固定在单向轴承4的内侧并与单向轴承4同轴，其轴与横梁9水平垂直并活动铰接，并设置在踏板复位装置10的后方。传动轴的后端锥齿轮与从动锥齿轮(7)相啮合，从动锥齿轮固定在横梁的后端。本发明研制了一种新型中轴前移无链自行车，本发明结构紧凑、骑行省力、方便、舒适、构思新颖、便于折叠携带。
摘要（英）：

The invention provides a novel chainless bicycle which relates to an improvement of a bicycle. A bevel gear (5-1) is arranged at the front end of a transmission shaft (5); a bevel gear (5-2) is arranged at the back end of the transmission shaft; the middle part of a pedal resetting device (10) is fixed at the front end of a beam (9) through a fixing device (11) and behind a front wheel (2); the front ends of two pedals (6) are respectively fixed at the two ends of the pedal resetting device (10); a driving bevel gear 8 is fixed on the inner side of a one-way bearing (4) and is coaxial with theone-way bearing (4); the shaft of the driving bevel gear (8) is horizontally vertical to the beam (9) and is movably articulated with the beam (9) and arranged behind the pedal resetting device (10);and the bevel gear at the back end of the transmission shaft is meshed with a driven bevel gear (7) which is fixed at the back end of the beam. The invention develops a novel chainless bicycle with aforward-shifting middle shaft, and has the advantages of compact structure, labor saving, convenience and comfort in riding, novel conception and convenient folding and carrying.
