A retarder is a device used to augment or replace some of the functions of primary friction-based braking systems, usually on heavy vehicles. Retarders serve to slow vehicles, or maintain a steady speed on declines, and help prevent the vehicle from running away by accelerating down the decline.They are not usually capable of bringing vehicles to a standstill, as their effectiveness diminishes as vehicle speed lowers.hey are usually used as an additional assistance to slow vehicles, with the final braking done by a conventional friction braking system. As the friction brake will be used less, particularly at higher speeds, their service life is increased.
The transmission retarder is enabled by a switch on the driver's console. When enabled, the transmission retarder is activated by two different methods; either with the application of the service brake pedal or by releasing the throttle pedal. A joystick on the driver's console selects the amount of retardation.he hydraulic retarder is a most simple device, and has only one moving part -- a rotor or paddle wheel.. The truck wheels turn the rotor through the transmission. The rotor throws the oil in the rotor cavity against the fixed stator vanes, which resist the oil flow.
