The hydrodynamic retarder is applied to a braking auxiliary system of a commercial vehicle, is arranged on the outer side of a vehicle gearbox or a vehicle frame, and a rotor is connected with a rotating shaft through a gear. When the magnetorheological fluid works, the magnetorheological fluid is controlled to fill the working cavity between the rotor and the stator to form pressure. When the rotor rotates, the rotor and the stator generate certain torque, the rotor generates certain braking force on the rotating shaft, the kinetic energy of the automobile is converted into the heat energy of the working liquid of the retarder, and the heat energy is dissipated into the cooling system through the plates.
Because the hydraulic retarder is a device for converting kinetic energy into heat energy, the temperature of hydraulic oil in an oil storage cavity is higher during the operation of the hydraulic retarder, so that the oil storage cavity is required to have enough volume, but the volume of the oil storage cavity of the conventional hydraulic retarder is limited due to the limitation of the installation position and the installation space.
