The invention discloses a double-motor single-speed parallel-axis electric drive axle. The invention belongs to the technical field of automobile manufacturing. The electric drive axle mainly solves the problems that an existing electric drive axle occupies the arrangement space of a chassis structure and influences the arrangement number of batteries. The electric drive axle is mainly characterized by comprising a first motor, a second motor, a gear box, a transmission shaft assembly, a hub speed reducer assembly, a first wheel and a second wheel; the first motor and the second motor are mounted on the two sides of the gear box respectively; the speed reducer assembly is arranged in the gear box and comprises a first-stage driving gear, a first-stage driven gear, a second-stage driving gear and a second-stage driven gear, wherein the first-stage driving gear and the first-stage driven gear are meshed, and the second-stage driving gear and the second-stage driven gear are meshed; and motor shafts of the first motor and the second motor are parallel to a transmission shaft of the transmission shaft assembly. The electric drive axle has the characteristics of relatively small occupied chassis structure arrangement space, no influence on the arrangement number of batteries, wide efficient working area of the motors, high energy utilization rate, long driving range of a vehicle andcapability of considering the dynamic property and economy of the whole vehicle, and is mainly used for the double-motor single-speed parallel-axis electric drive axle.
