The DMF from ZF decouples engine vibrations in an ideal manner, making rattling and booming a thing of the past. The flywheel mass is divided into a primary and a secondary mass, with the secondary flywheel mounted to the primary flywheel by a bearing that allows it to rotate.
A highly efficient, grease-filled spring and damping system operates between the two masses. This means that the resonance speed of the dual mass flywheel – in contrast to conventional clutch discs with torsional dampers – lies below the engine’s idle speed.
The axial space requirements for a DMF with clutch are similar to those for a twin-disc clutch. Thus the DMF can usually be integrated into existing powertrain configurations.
