The invention provides an in-wheel two-gear automatic transmission and a power-interruption-free gear-shifting control method. In the transmission, the power of a driving motor is input into a sun gear of an NW type compound planetary gear train transmission mechanism, is output by a rear planet carrier after being decelerated by the NW type compound planetary gear train transmission mechanism andis output to a small sun gear of a WW type compound planetary gear train transmission mechanism, the final power is output to wheels from a large sun gear of the WW type compound planetary gear traintransmission mechanism, and the two-gear transmission ratio change of the WW type compound planetary gear train is realized through the coordinated work of a pawl type controllable overrunning clutchand a multi-piece wet friction clutch, so that a vehicle can move forward by changing to the first gear and the second gear and move backward by changing to the first gear, and neutral gear of the vehicle can also be achieved. The in-wheel two-gear automatic transmission and the power-interruption-free gear-shifting control method can realize quick, power-interruption-free and smooth gear shifting by controlling the action of a motor of an actuating mechanism and optimizing the gear shifting process while meeting the requirement of larger transmission ratio required by the transmission in a high-speed motor wheel.

    本发明提供了一种轮内两挡自动变速器及无动力中断换挡控制方法,所述变速器中,驱动电机动力输入NW型复合行星轮系传动机构的太阳轮,经NW型复合行星轮系传动机构减速后由其后行星架输出,并输出至WW型复合行星轮系传动机构的小太阳轮,最终动力由WW型复合行星轮系传动机构的大太阳轮输出至车轮,并经过棘爪式可控超越离合器和多片湿式摩擦离合器协调工作实现WW型复合行星轮机构两挡传动比变化,实现车辆一挡前进、二挡前进、一挡倒退及空挡。本发明在满足高速电机轮内传动所需较大传动比的同时,通过控制执行机构电机动作及换挡过程优化,可实现快速、无动力中断且平顺换挡。
