The transmission device comprises a mechanical variable-speed transmission mechanism and a hydraulic driving system, the mechanical variable-speed transmission mechanism comprises an intermediate shaft, a main shaft and a first transmission shaft, the intermediate shaft is in transmission connection with an input shaft through a first gear set, and the intermediate shaft is in transmission connection with the main shaft through an intermediate gear set; the main shaft is in transmission connection with a first transmission shaft through a second gear set, the first transmission shaft is in transmission connection with an output shaft through a third gear set, the hydraulic driving system comprises a hydraulic pump and a retarding hydraulic motor, and the hydraulic pump is communicated with the retarding hydraulic motor through a hydraulic oil pipe. The hydraulic pump is in transmission connection with the intermediate shaft through the fourth gear set. By arranging the mechanical variable-speed transmission mechanism and the hydraulic driving system, when the vehicle runs normally, the transmission ratio is changed and the torque is transmitted through the mechanical variable-speed transmission mechanism, and the hydraulic pump and the retarding hydraulic motor in the hydraulic driving system are in an interrupted state.
