Therefore, using a Telma retarder is synonym of safety and comfort for the driver as well as for his passengers. Engine retarders. Retarder Auxiliary Brake Systems Explained. Telma induction braking systems dissipate the braking energy by generating eddy currents. The retarder provides an extended life of the vehicle’s standard braking system and allows for faster movement with much more security and stability. BRAKE FADE. The retardance of the plate is the product of the birefringence of the material and the thickness of the plate. 3 years ago. The transmission retarder is enabled by a switch on the driver's console. Use of Engine Retarder Brakes Engine retarder brakes are used in many heavy trucks as a supplement to the vehicle’s service brakes. In this technique retarder device is used to augment or replace some of the functionsof primary friction-based braking systems, usually on heavy vehicles. Allison Transmission describes the function of an engine brake as a retarder that effectively part-suffocates the engine, to help slow the vehicle down. In the case of Scania, the last stage of the retarder. The Jake Brake is RPM hungry, it needs High Engine RPM to be effective and at times that may hurt applications on fire apparatus. Retarders help to slow vehicles, reducing drivers' need to use brakes. The Retarder is an independent, wear-free and maintenance-free brake system for vehicles and dynamometers. It might say something like "12+R". The air enters the engine at atmospheric pressure in a normal diesel engine or under pressure in a turbocharged diesel. * With some motorcoaches, the ABS is designed to deactivate the retarder when wheel-lock starts. The retarders are designed with no servicable parts which wear out, therefore extensive use of retarder systems has no cost. Brake Power Supply HS-PWS This truck system is what provides that alternate braking capacity when needed. I´m renovating at the moment two Telma CC160 retarders and now charting options of power supplies. Auto engine brake? For some models of transmission with retarder of the Volvo and Scania in the game both the motor brake and the retarder work together.
