What is bus retarder?
A vehicle retarder, when actuated, provides an auxiliary and independent braking system for absorbing a portion of the kinetic energy of a decelerating bus. By sharing braking with the service brake system, the retarder results in cooler brakes and increased lining life.
How does a Volvo retarder work?
The retarder is fitted with a cruise control function that makes it easier for the driver to maintain a constant speed when driving downhill. Since the retarder is connected to the propeller shaft, braking power is also utilised when changing gears.
What is the function of retarder?
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 while traveling down a hill, and help prevent the vehicle from “running away” by accelerating down the hill.
How does Voith retarder work?
Using an oil supply that is independent of the transmission fluid, the oil in Voith’s oil retarders can tolerate the maximum permissible operating temperatures. The braking energy is transferred via the heat exchanger to the vehicle’s cooling circuit, where it is effectively dissipated.
What is the difference between retarder and engine brake?
The true engine brake (Jake brake) tends to be very loud in operation. Exhaust brakes tend to be quieter, but can still cause more noise. Retarders act downstream on the driveline; they seem to be more popular in Europe. They also tend to be much quieter outside the truck.
What is retarder brake?
Engine retarder brakes are used in many heavy trucks as a supplement to the vehicle’s service brakes. The principle behind the engine retarder brake is that it changes the action of the exhaust valves, turning the engine into an air compressor.
When should you not use retarders?
Explanation Retarders are mechanisms in some vehicles that help slow a vehicle and reduce the need for braking. However, using a retarder may cause wheels to skid when they have poor traction. Turn off retarders when traveling under wet, snowy, or icy conditions.
What are the 4 types of retarders?
Explanation Retarders are mechanisms in some vehicles that help slow the vehicle and reduce the need for braking. The four basic types of retarders are exhaust, engine, hydraulic, and electric.
Is retarder the same as engine brake?
They are different things. Engine braking will use engine electrical power to slow down the truck, while the retarder will use the transmission “power” to slow down the truck.
