The invention discloses a double-motor electric drive axle, and belongs to the technical field of new energy automobile power assemblies. A tenth transmission gear is connected with a motor rotor and is meshed with a ninth transmission gear; the third transmission gear and the fourth transmission gear are connected with the output end of the gear shifting executing mechanism. The second driving motor is connected with the input end of the gear shifting executing mechanism. The seventh transmission gear is connected with the differential mechanism; the left and right half shafts are connected with the output end of the differential; the third transmission gear is meshed with a seventh transmission gear; the fourth transmission gear is meshed with an input gear outside the differential mechanism; the eighth transmission gear is connected with the ninth transmission gear and meshed with the seventh transmission gear or an input gear outside the differential mechanism. And the second driving motor selectively intervenes in and cooperates with the main power system to perform auxiliary driving so as to increase the driving power. Through a dual-motor combination mode and different dual-motor coupling control strategies, the motor load rate is increased, the motor operation efficiency is improved, and the energy consumption level of the whole vehicle is reduced.
