The invention relates to a stepping type weight-driven chainless lever labor-saving power device which can be used for any rickshaw. Driving devices such as a gear, one-way wheels, a sliding bearing,a crankshaft, a connecting rod, a lever, a pedal guide rail, a pulley, a knuckle bearing and a pedal are additionally arranged on a driving wheel shaft and a wheel drum of an original vehicle. By utilizing the weight or physical strength of a human body and the labor-saving effect of the lever, the pedal is treaded by feet and driven by the pedal and the like. Reciprocating motion of the lever isdirectly converted into circular motion, and the wheels are driven to advance. The device is simple in structure, transmission parts such as chain wheels, chains and flywheels are not needed, frictionresistance is reduced, circular motion of bicycles and manpower tricycles is changed into stepping type vertical up-and-down stepping, circular motion of the two legs is omitted, the exercise amountand strain of condyles, knees and hip joints of the human body are reduced, the knees and the hip are protected, and the device is beneficial to health. Meanwhile, riding is labor-saving, safe, easy to maintain, long in service life and high in speed and transmission reliability.

    本发明是一种踏步式体重驱动无链条杠杆省力动力装置,它可用于任何一种人力车。在原车驱动轮轴和轮鼓上加装齿轮、单向轮、滑动轴承、曲轴、连杆、杠杆、踏板导轨、滑轮、关节轴承、踏板等驱动器件。利用人体重量或体力和杠杆省力作用,用脚踩动踏板,通过踏板等驱动组合。直接将杠杆的往复运动转换为圆周运动,驱动车轮行进。本发明结构简单,不用链轮、链条、飞轮等传动零件,减少磨擦阻力,变现有自行车、人力三轮车的圆周运动为踏步式垂直上、下踏动,免去双腿圆周运动,减少人体髁、膝、髋关节的运动量和劳损,保护膝盖、臀部、有益健康。同时骑行省力、安全、维护容易、使用寿命长,速度及传动可靠性高。
