The invention relates to a dual-motor single-speed parallel-axis output electric drive axle. The invention belongs to the technical field of new energy vehicles. The problems that an existing single motor is low in efficiency and large in occupied chassis space due to the fact that a transmission chain is single in gear are mainly solved. The electric drive axle is mainly characterized by comprising a first motor, a second motor, a speed reducer, a differential mechanism, a first half shaft, a second half shaft, an independent suspension and an axle housing, wherein the speed reducer comprisestwo pairs of meshed primary speed reduction driving gears and primary speed reduction driven gears, and two meshed secondary speed reduction driving gears and a secondary speed reduction driven gear;the first-stage speed reduction driven gear and the second-stage speed reduction driving wheel are coaxially arranged; a first motor shaft of the first motor and the first first-stage driving gear are integrally designed, and a second motor shaft of the second motor and the second first-stage driving gear are integrally designed; and the independent suspension system is arranged between the middle part of the axle housing and the two wheel edges. The invention has the characteristics of compact structure, high transmission efficiency, convenience for chassis structural arrangement, and good dynamic property and economy of the whole vehicle.
