The invention relates to a chainless high-torque bicycle. Rod-rod fulcrums of pedals are arranged on a rear shaft, the distance between pedals and the rear shaft is a power arm, a resisting arm of the rod-rod is the distance between the rear shaft and an arc of an inner gear, arc-shaped teeth of the inner gear are meshed with the rear edge of a rear fork gear fixed on an extended rear lower fork, and the front edge of the rear fork gear is meshed with the rear edge of a front fork gear. And the front edge of the front fork gear is meshed with a flywheel on the rear shaft. The kinetic moment of a left pedal of a person is transmitted to the flywheel through the inner gear, the rear fork gear and the front fork gear. The defect that the pedal torque of a common bicycle changes violently is overcome, the direction of the pedal force is almost vertical to the direction of the force arm, and the output work is obviously increased under the same pedal force; the bending angle between the shank and the thigh is much smaller, so that tiredness is not easily caused; the weight of the whole person can be completely applied to the bicycle and can become power all the time, and the output power is large; compared with a common bicycle, stability is good, machining and manufacturing are convenient, and manufacturing cost is little increased.

    一种无链条大力矩自行车,脚踏板的杆杆支点在后轴,脚踏到后轴为动力臂,杆杆的阻力臂是后轴到内齿轮圆弧间的距离,内齿轮的弧形齿与固定在延长后下叉上的后叉齿轮的后边缘啮合,后叉齿轮的前边沿与前叉齿轮的后边缘啮合,前叉齿轮的前边沿与后轴上的飞轮啮合。人左脚踏板的动力矩通过内齿轮、后叉齿轮、前叉齿轮到飞轮。本发明纠正了常用自行车脚踏力矩变化剧烈的缺点,脚蹬力的方向与力臂的方向几乎是垂直的,同样的脚蹬力,输出功显著增大了;小腿和大腿之间弯折的角度小多了,不易累;可以将整个人重量全部施加到车上,人的重量可以一直成为动力,输出动力大了;比普通车稳定性好,加工制造方便,制造成本增加不多。
