Dual-electric-motor driving system

A dual-electric-motor driving system, characterized in that the dual-electric-motor driving system comprises 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 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;
• and the parking mechanism is integrated with the differential-lock mechanism, and is provided on one side of the differential-lock mechanism;
• and
• the differential-lock mechanism comprises a movable fluted disc, a fixed fluted disc and a fixed armature, the movable fluted disc is slidably connected to the output shaft of the first electric motor, the fixed fluted disc is fixedly connected to the output shaft of the second electric motor, and when relative rotation between the dual electric motors is required to be locked, the fixed armature is electrified to generate an electromagnetic force, to cause the movable fluted disc to move toward the fixed fluted disc, and contrate teeth on the movable fluted disc and the fixed fluted disc are engaged to realize the locking.
