The invention discloses a double-motor double-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 first wheel and a second wheel; the gear box comprises a speed reducer assembly, and the speed reducer assembly comprises a first-gear first-level driving gear, a first-gear first-level driven gear, a second-gear first-level driving gear, a second-gear first-level driven gear, a two-gear gear shifting system, a second-level driving gear and a second-level driven gear; the first motor and the second motor are mounted on the two sides of the gear box respectively; and motor shafts of the first motor andthe 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 motor efficient working area, high energy utilization rate, long vehicle driving range and capability of considering the dynamic propertyand economy of the whole vehicle, and is mainly used for the double-speed parallel-axis electric drive axle.
