The invention relates to a hydraulic transmission system with a brake retarder. A hydraulic retarder is matched with a transmission component in the following matching forms: the hydraulic retarder is connected in parallel with a single head of a hydraulic transmission box, the hydraulic retarder is connected in series with the single head of the hydraulic transmission box, the hydraulic retarder is connected in series with a single head of a hydraulic torque converter, the hydraulic retarder is connected in series with the far end of an axle gear box, and the hydraulic retarder is connected in series with double heads of the hydraulic transmission box. Various matching forms can be transmitted to the hydraulic retarder through the corresponding axle gear box, and the vehicle speed control is achieved. When the vehicle travels, the hydraulic retarder is matched with the transmission component, when the vehicle travels at a high speed, the hydraulic retarder is in a disengaged state, and an engine outputs power to drive the vehicle to travel through the transmission component. When the vehicle is braked, the transmission component is automatically disengaged, the hydraulic retarder generates braking force, the kinetic energy of the vehicle is converted into heat energy, the running speed of the vehicle is reduced, and the vehicle speed control is achieved. The device has the advantages of being simple in structure, convenient to cooperate, effective in braking and safe in operation.
