The invention discloses a novel bicycle driving structure which comprises a power bevel gear, a toothed chain and a gear fixing frame, and two sides of the power bevel gear are in engaged power connection with a first bevel gear and a second bevel gear correspondingly. The first bevel gear and the second bevel gear are respectively connected with a first connecting shaft and a second connecting shaft; the first connecting shaft and the second connecting shaft are respectively connected with a first gear and a second gear; a third gear and a fourth gear are arranged on the gear fixing frame, the outer rings of the first gear, the second gear, the third gear and the fourth gear are all in power engagement connection with a toothed chain to form a closed power system, and a left pedal and a right pedal are arranged on the toothed chain. The novel bicycle driving structure is simple in structure, a circle of rotation can be completed by treading up and down for a short distance, the acceleration is high, compared with a common bicycle, centrifugal force on feet cannot be generated during high-speed rotation, labor is saved during climbing, power interruption cannot be generated, and the novel bicycle driving structure is suitable for a wide range of people.
本发明公开了一种新型自行车驱动结构,包括动力锥形齿轮、齿链和齿轮固定架,所述动力锥形齿轮的两侧分别啮合动力连接第一锥形齿轮和第二锥形齿轮,所述第一锥形齿轮和第二锥形齿轮分别连接第一连接轴和第二连接轴,第一连接轴和第二连接轴分别连接第一齿轮和第二齿轮,所述齿轮固定架上设置有第三齿轮和第四齿轮,所述第一齿轮、第二齿轮、第三齿轮和第四齿轮的外圈均动力啮合连接齿链,并形成闭合的动力系统,所述齿链上分别设置有左踏板和右踏板。本发明的新型自行车驱动结构,结构简单,上下踩踏很短的距离,即可完成一圈的转动,提速快,跟普通自行车相比高速转动不会产生对脚的离心力,爬坡省力,不会产生动力中断,且适用人群广。
