| Like all Voith Retarders, the Aquatarder, too, operates after the hydrodynamic principle. The operating medium “cooling water“ is accelerated into the operating circuit by the rotor which is driven by the engine crank shaft, and then again decelerated in the stator. Braking torque is created depending on the filling level between rotor and stator. Through the rotor and the crank shaft, the braking torque is introduced to the vehicle driveline which, in turn, is braked. Kinetic energy created in this process is fully converted into thermal energy in the hydrodynamic chamber of the retarder, and is taken up directly by the cooling water. The heated cooling water is cooled down via the vehicle cooling system. The Aquatarder brakes wear and maintenance-free. |
