The invention discloses a double-motor integrated two-gear AMT double-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, an AMT assembly, a differential mechanism, a first half shaft and a second half shaft; the speed reducercomprises a first-stage driving gear and a second-gear first-stage speed reduction driven gear which are meshed with each other, a first-stage driving gear and a first-gear first-stage speed reduction driven gear which are meshed with each other, and two second-stage speed reducer driving wheels and a second-stage speed reduction driven wheel which are meshed; the first motor, the second motor, the second-stage speed reduction driven wheel and the differential mechanism are in parallel axis arrangement. The electric drive axle has the advantages of being coaxial and compact in structure design, high in transmission efficiency, convenient to arrange a chassis structure, light in dead weight and capable of improving the economy of a whole vehicle, and is mainly used for the double-motor integrated two-gear AMT double-speed parallel-axis output two-stage speed reduction electric drive axle.
