Product Description
Performance
There is a stator with blades and a rotor with blades in the working chamber of the hydraulic retarder, and the rotor rotates together with the drive shaft. When the retarder is working, the ECU controls the opening of the proportional valve to pump the gas from the whole vehicle gas source into the retarder oil cell shell, and the gas presses the retarder oil into the working chamber.
The rotor rotates at high speed and hits the oil on the stator, generating a reaction force, i.e. braking torque, which in turn acts to reduce the speed of the vehicle (the more oil, the greater the reaction force). The heated oil flows out of the working chamber and into the heat exchanger, where the heat is taken away by the engine coolant and transferred to the atmosphere through the engine cooling water tank.
The retarder converts the kinetic energy of the vehicle into heat energy, which is then transferred to the atmosphere through the engine water circulation system to achieve constant speed and deceleration of the vehicle. As the retarder is a braking force generated by churning oil, the retarder force is very weak when the drive shaft speed is too low. Generally the vehicle can exert a lot of braking power at speeds above 30km/h.
Performance
Retarder is only an auxiliary braking device, emergency braking and stopping still need to apply the brakes.
The size of the retarder power has nothing to do with the engine speed, only with the drive shaft speed (car speed), but the engine speed will affect the speed of the water cycle, the engine speed is too low, the retarder water temperature can easily rise, beyond the limit, the retarder will drop the torque or quit, affecting the retarder use time and effect. So constant speed gear, the engine speed should generally be maintained at 1500 rpm or more.
The power of the retarder is not affected when the gearbox is in neutral, only the engine speed is in idle when in neutral, only about 800 rpm, the water circulation is too slow, the retarder will quit after a few dozen seconds of use, so the retarder cannot be put in neutral when the gearbox is in use.
In an emergency (non-slippery or turning conditions), you can directly pull the retarder in the highest gear to achieve the role of fast braking, will not damage the retarder. However, due to the rapid rise in water temperature, the retarder will exit at high temperature within ten seconds or so and lose braking power.
