Introduction of Foster hydraulic retarder The hydraulic retarder is a kind of vehicle auxiliary braking device, which changes the kinetic energy of the vehicle braking into thermal energy to achieve the function of vehicle retardation. | ||||||||
Working principle of hydraulic retarder Controller staging control solenoid proportional valve opening degree, the gas taken from the whole vehicle gas source controller staging control solenoid proportional valve opening degree, the gas taken from the whole vehicle gas source through the solenoid valve into the retarder oil pool shell, the oil pressure into the work between the stator and rotor through the solenoid valve into the retarder oil pool shell, the oil pressure into the work between the stator and rotor, transport, cavity, the movement of the rotor to accelerate the oil, and act to the stator, the stator force the oil to produce a reaction force on the rotor, thus and act on the stator, the stator forces the oil to produce a reaction force on the rotor, thus producing The braking torque is generated. In the process of generating braking force, the kinetic energy of the vehicle is converted into executive energy, and the whole vehicle cooling In the process of generating braking force, the kinetic energy of the vehicle is transformed into heat energy, and the heat is taken away and dissipated by the heat dissipation system of the whole vehicle, so that continuous braking can be realized when thermal equilibrium is reached. | ||||||||
