3D Animation Voith VR115 CT Retarder Working Principles

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.

This animation for Voith illustrates how the VR115 CT retarder works. The technical details are visualized in a particularly impressive way, showing not only the relationships in the vehicle, but also the individual components of the retarder. Watch the video from Stoll von Gáti for more info:

The Voith 115 CT is a step-up gear retarder with a high braking torque. It has a self-contained oil supply system and is integrated into the vehicle’s braking management system. In conjunction with the service brakes, it provides optimal braking action.

At the same time, the retarder increases riding comfort, for example via the v-constant function that keeps speed constant downhill, in the same way as downhill cruise control, without the additional use of the service brakes.
