New technology and the associated demands on a modern clutch system require a further development of existing systems to meet these requirements. Main focus is on the power flow between the engine and the transmission: Rapid and reliable separation and connection of the power flow, smooth moving-off, damping of engine vibrations, easy operation, long life without sacrificing comfort and a requirement to minimize installation space.
In order to meet these requirements, dynamic component inspections and operational strength tests must be carried out on your coupling components or 2-mass flywheels, with dynamic centrifugal forces (with rotational momentum, with corresponding centrifugal forces). Furthermore, the real wear of your clutch components and damping elements must be examined. In addition, torque characteristics must be determined over the angle of rotation.
The dynamic torsion test stand is designed for the operational fatigue testing of torsional vibration dampers under rotational speed. These are used as damping elements in two-mass flywheels of modern clutch systems. Damping elements serve to reduce the vibrations generated by the clutch and the rotating transmission masses.
The permanent behavior of the bearing and damping elements in the flywheel is examined. Furthermore, multi-stage torsional characteristics (clutch hysteresis loops) can be determined as a function of the rotational speed during torque changes (thrust and tension).
The nominal torques of up to 2500 Nm and high-frequency torsional vibrations are generated by a spinning Hydropuls rotary cylinder with a rotary vane principle. This is rotated at a controllable speed together with the test specimen. As a result, all loads occurring under operating conditions can be simulated on the test specimen.
