Braking Retarder for Truck

Hydraulic retarder braking The stator is integrated with the retarder housing and connected to the rear end or frame of the transmission. The rotor is connected to the transmission shaft through a hollow shaft, and blades are cast on both the rotor and stator. During operation, pressure is applied to the oil pool through the operation of the control valve to fill the working fluid into the working cavity between the rotor and stator. When the rotor rotates, a torque is applied to the stator through the working fluid, and the reverse torque of the stator becomes the braking torque of the rotor. Its value depends on the amount of fluid and pressure in the working chamber (determined according to the brake strength gear set by the control valve), as well as the rotational speed of the rotor. The kinetic energy of the vehicle is consumed by the friction of the working fluid and the impact on the stator, which is converted into heat energy, causing the temperature of the working flui…
