摘　　要：针对现有金属带无级变速器效率低,功率容量低的缺点,提出了采用行星齿轮功率分流式无级变速传动的结构,使用电机进行调速的方案,并以此为基础,探讨了其在各个工况下的运动规律。The advantages and disadvantages of the Automotive automatic transmission are introduced briefly. To counter the characteristics of low efficiency and low power capacity of current CVT, the scheme is proposed which adopts Planetary Gear power split structure and uses motor to change speed. Based on what mentioned above, the motion law is studied under various working conditions.
