The invention discloses a hydraulic braking device special for a heavy-duty truck. The hydraulic braking device comprises a fixed plate, a hydraulic pump, a gear transmission mechanism, a hydraulic pump engaging and disengaging device and a control device which are arranged on a truck chassis, wherein the hydraulic pump is hinged to the upper surface of the fixed plate, and the axis of the hydraulic pump is parallel to the axis of a truck driving axle; a gear transmission mechanism is arranged between a hydraulic pump driving axle and the truck driving axle; the hydraulic pump engaging and disengaging device for driving the hydraulic pump to rotate about the hinge point of the the hydraulic pump and fixed plate is arranged between the hydraulic pump and the fixed plate; a controllable one-way valve is arranged on an oil inlet pipe of the hydraulic pump. The rotation of the truck driving axle is retarded by taking the hydraulic pump as a resistance device, and resistance opposite to the rotating direction of the truck driving axle is provided for the truck driving axle; moreover, the oil inlet resistance of the hydraulic pump is adjusted through a controllable one-way valve, the magnitude of the braking force is adjusted, and flexible braking is performed without mechanical friction in a braking process, so that braking failures caused by aging of friction parts are avoided, and the driving safety is ensured.
