The invention discloses a hydraulic retarder for a heavy truck axle. The hydraulic retarder is characterized by comprising a gear pump (2); the oil inlet of the gear pump (2) is connected with an oil tank (1), while the oil outlet of the gear pump (2) is connected with a valve block; the valve block is composed of a pilot overflow valve (3) and a throttling valve (4), and is mounted on the oil tank (1); the oil outlet of the valve block is connected with a heat exchanger (5); the heat exchanger (5) is mounted on the oil tank (1) by use of a flange; according to the retarder, the structure of the original pair of gears on the main retarder of the middle axle is modified, and compared with a hydraulic speed reducer and an electrical vortex speed reducer, the hydraulic retarder has the advantages of simple and compact structure, low cost and easy control of braking power; compared with the traditional axle without the retarder, the retarder is used for assisting braking, so that the service life of a brake block and a tire can be remarkably prolonged and the safety of a vehicle can be improved.
