How does Telma retarder work?
A TELMA Electro-magnetic Retarder is an assembly of electro magnetic coils which, when activated by an electrical current, creates eddy ( Foucault ) currents between two rotors and a stator and retards the movement of the rotor. The energy created in the operation of a Telma retarder is converted into heat.
How does a 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.
Are retarders mandatory?
In most European countries, retarders are mandatory fitment for buses, coaches and some heavy transport vehicles because they significantly improve the safety of these vehicles. Fitted into the driveline of a vehicle the Telma retarder acts directly on the driven wheels and reduces the speed of a vehicle.
What is a retarder brake?
Retarders are used to further improve the braking performance on commercial vehicles. Like engine brakes, they are wear-free continuous brakes. Retarders relieve the service brake and increase the active safety and cost-effectiveness of commercial vehicles.
Is a jake brake a retarder?
Although they are both brake retarder systems, Jake Brakes and Exhaust Brakes are essentially opposites in how they function. As you now know, a Jake Brake releases the compressed air that gets trapped in the cylinders.
What is retarder brake?
What is retarder braking system?
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.
What’s the stab braking method?
Stab braking: Release the brakes when the wheels lock up. As soon as the wheels start rolling, put on the brakes fully again. It can take up to 1 second for the wheels to start rolling after you release the brakes. If you reapply the brakes before the wheels start rolling, the vehicle will not straighten out.
What is a major caution when using retarders?
Caution. When your drive wheels have poor traction, the retarder may cause them to skid. Therefore, you should turn the retarder off whenever the road is wet, icy, or snow covered.
