The present disclosure discloses a dual-electric-motor driving system, wherein the dual-electric-motor driving system includes a first electric motor, a second electric motor, two sets of gear reduction mechanisms, a differential-lock mechanism and a parking mechanism; the first electric motor and the second electric motor are arranged coaxially, first-stage pinions (51,61) of the two sets of gear reduction mechanisms are provided respectively on an output shaft of the first electric motor and an output shaft of the second electric motor, and the differential-lock mechanism is provided at tips of the output shaft of the first electric motor and the output shaft of the second electric motor; the differential-lock mechanism includes a movable fluted disc (41), a fixed fluted disc (44) and a fixed armature (43), and when relative rotation between the dual electric motors is required to be locked, the movable fluted disc (41) and the fixed fluted disc (44) realize engagement-locking in the axial direction; and when it is required to park, the parking function can be realized by combinating the differential-lock mechanism and the parking mechanism. The above structure of the dual-electric-motor driving system can reduce the axial dimension of the gearbox, and, by using the differential-lock mechanism, realizes the coupling between the output powers of the dual electric motors, increases the maximum output power, and improves the trap escaping capacity of the vehicle.
