The invention discloses a dual-motor single-speed two-stage deceleration strip wheel-side deceleration independent suspension parallel-axis electric drive axle. The invention belongs to the technicalfield of new energy vehicles. The problems that an existing single motor is high in energy loss, low in transmission efficiency and poor in power performance are mainly solved. The electric drive axleis mainly characterized by comprising a first motor, a second motor, a first half shaft, a second half shaft, a first hub reduction speed reducer assembly, a second hub reduction speed reducer assembly, a first speed reducer assembly and a second speed reducer assembly; the first motor and the second motor are respectively arranged on the first speed reducer assembly and the second speed reducerassembly; the first speed reducer assembly and the second speed reducer assembly each comprise an input gear, a first-stage speed reduction gear, a second-stage speed reduction gear, an output gear and an intermediate shaft; the two ends of each half shaft are connected with the hub speed reducer assembly and the speed reducer assembly respectively. The first half shaft, the second half shaft, thefirst motor shaft and the second motor shaft are parallel. The parallel-shaft electric drive axle has the characteristics of dual-motor driving, mutual independence of left and right transmission systems, elimination of a mechanical differential mechanism and saving of the space and weight of a chassis, and is mainly used for a single-speed two-stage deceleration belt hub speed reduction independent suspension.
