The invention discloses a dual-motor driving system and an electric automobile. The dual-motor driving system comprises a first motor, a second motor and a speed reducer, wherein a first through hole is formed in a first rotating shaft of the first motor along the axis; a second through hole is formed in the axis of the second motor; a first output shaft is inserted into the first through hole, one end of the first output shaft is in transmission connection with one power output end, a second output shaft is inserted into the second through hole, and one end of the second output shaft is in transmission connection with the other power output end; a first transmission assembly is used for connecting or disconnecting power transmission between the first rotating shaft and the first output shaft, and a second transmission assembly is used for connecting or disconnecting power transmission between the first rotating shaft and the power input end; and a third transmission assembly is used for connecting or disconnecting power transmission between the second rotating shaft and the second output shaft, and a fourth transmission assembly is used for connecting or disconnecting power transmission between the second rotating shaft and the power input end. The dual-motor driving system is compact in structure, and the occupied space can be reduced.

    本发明公开了一种双电机驱动系统及电动汽车,包括第一电机、第二电机和减速器,第一电机的第一转轴沿轴心设有第一通孔;第二电机的轴心设有第二通孔;第一输出轴插设在第一通孔中,且第一输出轴的一端与一个动力输出端传动连接,第二输出轴插设在第二通孔中,且第二输出轴的一端与另一个动力输出端传动连接;第一传动组件用于连通或者断开第一转轴与第一输出轴之间的动力传递,第二传动组件用于连通或者断开第一转轴与动力输入端之间的动力传递;第三传动组件用于连通或者断开第二转轴与第二输出轴之间的动力传递,第四传动组件用于连通或者断开第二转轴与动力输入端之间的动力传递。本发明的双电机驱动系统结构紧凑,能够减少空间占用。
