The invention relates to a bicycle driving mechanism and a bicycle, the driving mechanism comprises a left output shaft, a right output shaft and a gear set coupler, a left crank and a left crank chain wheel are fixedly arranged on the left output shaft, a right crank and a right crank chain wheel are fixedly arranged on the right output shaft, and flywheels are respectively arranged on two sides of a rear axle. The left crank chain wheel and the right crank chain wheel are respectively connected with the flywheels on the corresponding sides through chains; the gear set coupler is connected with the left output shaft and the right output shaft, and enables the rotation directions of the left output shaft and the right output shaft to be opposite. The bicycle uses the driving mechanism. According to the bicycle driving mechanism provided by the invention, the left half shaft and the right half shaft of the middle driving shaft can be in a synchronous reverse rotation state, alternate treading and power generation of left and right feet are realized, cranks are prevented from reaching 'dead points', continuous exertion for riding can be realized, and the treading efficiency is improved.
本发明涉及一种自行车驱动机构及自行车,驱动机构包括左输出轴、右输出轴以及齿轮组联轴器,左输出轴上固定设置有左曲柄和左曲柄链轮,右输出轴上固定设置有右曲柄和右曲柄链轮,在后车轴两侧分别设置有一飞轮,左曲柄链轮和右曲柄链轮分别通过链条与对应侧的飞轮连接;齿轮组联轴器连接所述左输出轴和右输出轴,并且使左输出轴和右输出轴的转动方向相反;使用上述驱动机构的自行车。本发明所提供的自行车驱动机构,能够使中间的驱动轴的左右两个半轴处于同步反向旋转的状态,实现左右脚交替踩踏发力,避免曲柄到达“乏点”,可连续发力骑行,提高蹬踏的效率。
