The invention discloses a power uninterruptible system and method for a new energy vehicle. The driving device comprises a first driving motor assembly, a second driving motor assembly and a gearbox, the output end of the first driving motor assembly is connected with the input end of the gearbox, and the output end of the gearbox is connected with wheels through a transmission shaft and a rear axle. A gearbox input shaft, a gearbox intermediate shaft, a gearbox third shaft, a gearbox fourth shaft and a gearbox output shaft are arranged in the gearbox; a fourth-gear gear, a third-gear gear, a second-gear gear, a first-gear gear, a floating gear, a fixedly-connected third gear shifting combination sleeve and a gearbox output flange are arranged on the gearbox output shaft, the third gear shifting combination sleeve is combined with or separated from the floating gear, and the gearbox output flange is connected with the transmission shaft. Power is not interrupted during gear shifting, the working rotating speed of the power takeoff cannot be decoupled from the vehicle speed, meanwhile, the performance and reliability of the whole vehicle are improved, and the weight and cost of the whole vehicle are reduced.

    本发明公开了一种新能源车辆动力不中断系统及方法。它包括第一驱动电机总成、第二驱动电机总成和变速箱,所述第一驱动电机总成输出端连接变速箱输入端,所述变速箱输出端通过传动轴,后桥连接车轮,所述变速箱内设有变速箱输入轴、变速箱中间轴、变速箱第三轴、变速箱第四轴和变速箱输出轴;所述变速箱输出轴上设置有四挡齿轮、三档齿轮、二档齿轮、一档齿轮、浮动齿轮、固连的第三换挡结合套、变速箱输出法兰,所述第三换挡结合套与浮动齿轮结合或分离,所述变速箱输出法兰与传动轴连接等。本发明实现换挡的时候动力不中断,取力器工作转速无法与车速解耦,同时也提升整车的性能和可靠性,降低了整车的重量和成本。
