The invention relates to a double-motor pure-electric-drive few-gear power-uninterrupted drive axle which comprises drive motors including a first main drive motor and a second main drive motor which are coaxially arranged in parallel; the speed reducing mechanism comprises a first planetary gear set connected with the first main drive motor and a second planetary gear set connected with the second main drive motor, and the output end of the first planetary gear set and the output end of the second planetary gear set are fixedly connected through a connecting shaft; and a gear shifting mechanism including a first gear shifting mechanism and a second gear shifting mechanism which perform switching operation on the first planetary gear set and the second planetary gear set. The driving axle comprises a differential mechanism in transmission connection with the connecting shaft and a driving wheel connected with the differential mechanism through a driving half 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纯电驱动的少挡动力不中断驱动桥,包括:驱动电机,其包括同轴并联设置的第一主驱电机和第二主驱电机;减速机构,其包括与第一主驱电机连接的第一行星齿轮组,以及与第二主驱电机连接的第二行星齿轮组,第一行星齿轮组和第二行星齿轮组的输出端通过连接轴固定连接;换挡机构,其包括将第一行星齿轮组和将第二行星齿轮组进行切换操作的第一换挡机构和第二换挡机构。驱动车桥,其包括与连接轴传动连接的差速器,以及通过驱动半轴与差速器连接的驱动轮。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。
