Turbo Retarder Clutch VIAB

The Turbo Retarder Clutch VIAB is a completely new start-up and braking system

With a fill-regulated, hydrodynamic fluid coupling as the main component, it unites the hydrodynamic start-up and hydrodynamic braking functions into one system.

 

Handling heavy transporters made easy:

The Turbo Retarder Clutch VIAB

 



Powerful start-up and safe braking - with no wear and for loads up to 250 tons. With the Turbo Retarder Clutch (from the German: Wear-free Integrated Starting and Braking system), two elements that appear to be mutually exclusive work together: The advantages of hydrodynamics when starting and braking with the high efficiencies of a mechanical driveline while driving.

Stress and tension behind the wheel? Not anymore. VIAB scores high when it comes to sensitive start-up and braking behaviour, as well as driving comfort. Just put your foot on the metal. As usual, simply pull the lever and the retarder decelerates safety and without wear. As many times as you like. Forget about overheating problems and all the other disadvantages of traditional torque converter solutions.

Experience it for yourself: The Turbo Retarder Clutch VIAB is a standard feature in the Mercedes Benz Actros SLT.

Upon start-up, the motor transfers power via the hydrodynamic circuit, as well as the downstream free wheel, to the transmission input shaft. Parallel to the circuit, a conventional friction coupling is arranged as a converter coupling.

When braking, the turbine brake arrests the turbine wheel. The system turns into a high performing retarder.
