The invention discloses a pure electric double-gear planet row driving system. A motor of the pure electric double-gear planet row driving system drives double-gear planet rows, each gear planet row is composed of an input sun gear, a planet gear set and an output sun gear, each gear of the output sun gear outputs power, and when power switching of two speed ratios is achieved by selecting closingand releasing of two sets of brakes, gear shifting power connection is rapid and smooth; and meanwhile, the two sun gears are responsible for input and output of power of the planet row correspondingly, a gear ring with a large diameter is not needed, and the whole vehicle is concise in power structure, low in loss, high in transmission efficiency and suitable for being applied to a pure electricvehicle driving system.
本发明公开了一种纯电动双挡行星排驱动系统,其电机驱动双挡行星排,各挡行星排均由输入太阳轮、行星轮组和输出太阳轮构成,各挡输出太阳轮输出动力,当通过选择两组制动器的闭合和释放实现两种速比的动力切换,换挡动力衔接迅速平顺;同时,两太阳轮分别负责行星排动力的输入和输出,无需直径较大的齿圈,整车动力结构简洁、损耗低、传动效率高,适合应用于纯电动汽车驱动系统。
