摘　　要：针对轮毂电动机驱动存在低速爬坡时动力不足的问题,研究出一种全新的行星滚轮式轮毂无级变速器(Continuously Variable Transmission,CVT)。该CVT通过多组滚轮摩擦传动,可实现对轮毂的独立变速驱动;其轮毂内圈为内齿圈,由多个行星分布的齿轮驱动,以提升轮毂驱动功率;变速时,通过控制摩擦滚轮摆动角度,改变弧面中心轮与弧面分布轮的实际工作半径,以实现变速过程的连续性与稳定性。使用Adams软件进行了运动仿真,结果表明,该CVT变速平稳、速度连续,具有传动效率高、运动平稳的特点。The wheel motor drive has the problem of insufficient power at low speeds when climbing hills.In this study,a new planetary roller wheel continuously variable transmission(CVT)is developed,which achieves independent variable speed drive of the wheel hub by means of multiple sets of roller friction drives.The inner ring of the wheel is an internal gear ring,driven by multiple planetary distribution gears to increase the wheel drive power.The actual working radius of the centre and distribution wheels is changed by controlling the angle of oscillation of the friction rollers to achieve continuity and stability of the speed change process.Motion simulation experiments using Adams software conclude that the CVT has a smooth and continuous speed,high transmission efficiency and smooth motion.
