A rickshaw boosting pedaling crank device comprises a crank mechanism, balls and a boosting rotary arm; the crank mechanism comprises a crank, a shaft end gear arranged at one end of the crank and a pedal end gear arranged at the other end of the crank, and the crank is provided with a ball containing channel communicated with the shaft end gear and the pedal end gear; the balls abut against and make contact with one another, part of the balls are in meshing transmission with the shaft end gear, the other part of the balls are in meshing transmission with the pedal end gear, and the rest of the balls are contained in the ball containing channels respectively; one end of the boosting rotary arm is connected to the pedal end gear. Therefore, the structure is simple, and stable transmission can be achieved in a circular motion mode.

    本发明公开一种人力车的可增力踩踏曲柄装置,包括曲柄机构、滚珠及增力旋臂,曲柄机构包括曲柄、设置在曲柄的一端的轴端齿轮及设置在曲柄的另一端的踏板端齿轮,在曲柄设有与轴端齿轮和踏板端齿轮相通的容珠通道;各滚珠彼此相互抵贴接触,其中一部分的各滚珠与轴端齿轮啮合传动,另一部分的各滚珠与踏板端齿轮啮合传动,其余的各滚珠则分别容置在容珠通道中;增力旋臂的一端连接在踏板端齿轮。藉此,不仅结构简单且能够以圆周运动方式达成稳定传动。
