适用于人力车的摇杆驱动机构

适用于人力车的摇杆驱动机构用摇杆代替了传统人力车的曲柄,乘骑者踏动脚蹬时,摇杆绕中轴上下摆动,摆角小于100°,不存在驱动力臂为零的死点,而且可根据车辆载荷人工调整驱动力臂的长度,改变驱动力矩的大小和车辆的行走速度,具有很强的爬坡能力.如果爬坡不顺利时,车会停在坡道上而不后退,既能充分发挥人力的作用,又大大提高了乘骑的安全性.

The Rocker Driving Mechanism Applying to Manpower Vehicles

The rocker driving mechanism applying to manpower vehicles uses rockers instead of the traditional cranks.When a rider treadles-the rockers swing around a shaft up and down-with a swing angle less than100degree.The dead point where the driving arms of force is zero is not present.The length of the driving arms of force can be adjusted-according to the loading-to change the driving moment of force and the speed of the vehicle,it is very capable of grade climbing.If the vehicle can't climb forward-it will stop on the slope and won't slip down.As a result-the ma npower can be utilised efficiently and the safety of riding can be greatly improved.
