6 FAQs about [Hydraulic retarder energy storage]
What is a hydraulic retarder?
Hydraulic retarders are auxiliary braking devices that reduce the velocity of a vehicle, particularly when a ABSTRACT− vehicle is driven downhill. Such velocity reduction could reduce the potential risk caused by brake failure caused by the service brake working for a long time and the temperature of the brake shoe becomes extremely high.
Why are hydraulic retarders used in heavy-duty vehicles?
Hydraulic retarders are extensively used in heavy-duty vehicles because of their advantages, such as their large braking torque and long continuous operating hours. They can reduce the vehicle velocity by converting the kinetic energy of a traveling vehicle to the thermal energy of the working fluid.
What are the advantages of hydraulic retarders?
Compared with other auxiliary braking devices, hydraulic retarders have the advantages of high braking efficiency, durable braking force, and non-pollution (Mew et al., 2015). The rotor and stator form the working chamber of the hydraulic retarder. The stator is fixed on the vehicle, and the rotor is connected to the drive shaft.
What is a water medium retarder?
The water medium (WM) retarder is an auxiliary braking device that could convert the kinetic energy of the vehicle to the thermal energy of the coolant, and it is used instead of the service brake under non-emergency braking conditions.
How does a water medium retarder reduce vehicle velocity?
They can reduce the vehicle velocity by converting the kinetic energy of a traveling vehicle to the thermal energy of the working fluid. The water medium retarder is a new type of hydraulic retarder with the characteristics of high power density and simple structure.
Can a hydraulic retarder reduce the risk of brake failure?
Such velocity reduction could reduce the potential risk caused by brake failure caused by the service brake working for a long time and the temperature of the brake shoe becomes extremely high. This paper introduces the construction of the hydraulic retarder and proposes two mathematical models for the hydraulic retarder.
