The invention provides a hydraulic retarder. The hydraulic retarder comprises a pump body, a throttler, at least one rotor set and a synchronous gear set. Each rotor set comprises a main rotor and auxiliary rotors symmetrically distributed on the two sides of the main rotor. The main rotor and the auxiliary rotors are engaged with each other and are synchronized through the synchronous gear set.At least one blade is arranged on the side face of the main rotor, the at least one blade, the pump body, the main rotor and the auxiliary rotors form a closed space, grooves coupled with the blade are formed in the side faces of the auxiliary rotors, and gaps exist or pressure relief grooves are formed in the grooves when the blade is coupled with the grooves. According to the hydraulic retarder,mechanical energy is converted into high-pressure hydraulic energy, then the high-pressure hydraulic energy is converted into heat energy through the throttler, and therefore kinetic energy of the vehicle is converted into heat energy, the purposes of being free of abrasion, long in service life, high in performance and low in cost of the hydraulic retarder are achieved, and good application prospects are achieved.
