The invention relates to a double-motor single-intermediate-shaft power-immediate power-off electric drive system, and the system comprises drive motors which comprise a first main drive motor and a second main drive motor which are connected in parallel; the input shaft comprises a first input shaft which is in transmission connection with the first main driving motor and a second input shaft which is in transmission connection with the second main driving motor and coaxially sleeves the periphery of the first input shaft in an empty manner; the intermediate shaft is located on one side of the input shaft at intervals, and multiple sets of gear shifting gear trains are arranged between the intermediate shaft and the first input shaft and between the intermediate shaft and the second input shaft; and the output shaft is coaxially located at the tail end of the input shaft, and the output shaft is in transmission connection with the intermediate shaft. According to the invention, the gear shifting power is not interrupted, and the gear shifting comfort is greatly improved; and the torque output of the two motors can be matched in real time according to the wheel end torque required when the vehicle runs, so that the economical efficiency is greatly improved.

    本申请涉及一种双电机单中间轴动力不中断电驱系统,包括:驱动电机,其包括并联设置的第一主驱电机和第二主驱电机;输入轴,其包括与第一主驱电机传动连接第一输入轴,以及与第二主驱电机传动连接并同轴空套于所述第一输入轴外周的第二输入轴;中间轴,所述中间轴间隔位于所述输入轴的一侧,且中间轴与第一输入轴和第二输入轴之间均分别设有多组换挡齿轮系;输出轴,所述输出轴同轴位于所述输入轴的末端,且输出轴与所述中间轴传动连接。本申请可实现换挡动力不中断,极大的改善了换挡舒适性;并可根据车辆行驶时所需的轮端扭矩实时匹配两个电机的扭矩输出,极大的提升了经济性。
