The invention discloses a double-motor single-speed hub speed reduction parallel-axis electric drive axle. The invention belongs to the technical field 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 axle is mainly characterized by comprising a first motor,a second motor, a first output half shaft, a second output half shaft, a first hub speed reducer assembly, a second hub speed reducer assembly, a first speed reducer assembly and a second speed reducer assembly; the first motor and the second motor are mounted on the first speed reducer assembly and the second speed reducer assembly respectively. The first speed reducer assembly and the second speed reducer assembly comprise meshed input gears and reduction gears; the two ends of the first output half shaft are connected with the first hub speed reducer assembly and the first reduction gear respectively, and the two ends of the second output half shaft are connected with the second hub speed reducer assembly and the second reduction gear respectively; and the first output half shaft and the second output half shaft are parallel to the first motor shaft and the second motor shaft. The electric drive axle has the advantages of being simple in structure and capable of improving passing ability and dynamic property, and is mainly used for single-speed hub speed reduction parallel-axis electric drive axle.
