The invention discloses a double-motor single-speed parallel-axis output two-stage speed reduction electric drive axle. The invention belongs to the technical field of new energy vehicles. The electric drive axle mainly solves the problems that an existing electric drive axle is large in motor heating and occupies the arrangement space of a chassis structure. 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 and a second half shaft; the speed reducer comprises two pairs of meshed first-stage driving gear and first-stage driven gear, and two meshed second-stage speed reducer driving wheels and a second-stage speed reducer driven wheel; motor shafts of the first motor and the second motorare respectively integrated with the two first-stage driving gears; and the first motor, the second motor, the second-stage speed reduction driven wheel and a differential mechanism are arranged in parallel. The two-stage speed reduction electric drive axle has the advantages of being coaxial and compact in structure, high in transmission efficiency, convenient to arrange a chassis structure, light in self-weight and capable of improving the economical efficiency of a whole vehicle, and is mainly used for double-motor single-speed parallel-axis output.
