The invention discloses a multi-gear electric drive axle transmission device. Comprising a main motor, an auxiliary motor, a first half shaft, a second half shaft, a first clutch, a limited slip differential assembly connected with the first half shaft and the second half shaft, an intermediate shaft receiving power from the main motor and a first-gear transmission mechanism. The synchronizer is arranged on the intermediate shaft and selectively combined with the first-gear transmission mechanism and the second-gear transmission mechanism, and the first-gear transmission mechanism and the second-gear transmission mechanism are arranged to be used for transmitting power to the limited slip differential assembly. The first clutch is arranged to be used for controlling combination and separation between the auxiliary motor and the limited slip differential assembly. According to the multi-gear electric drive axle transmission device, the main motor and the auxiliary motor are combined, switching of three gears can be achieved, the main motor works in the normal running process, the double motors work at the same time in the climbing or accelerating process, the auxiliary motor works at the high speed, it can be guaranteed that the driving motor operates in the high-efficiency interval to the maximum extent, and the driving efficiency is improved. The high-efficiency interval of the motor is expanded, and the endurance mileage is improved.
