Key Facts
What can Dual Mass Flywheel for Commercial Vehicles provide?
Irregularities of modern engines are steadily rising. At the same time, the demands are increasing for noise reduction and comfort as well as the protection of the transmission and vibration-sensitive vehicle components. If the torsional damper in the clutch disk is not sufficient to damp engine vibrations in critical engine speed ranges, the Dual Mass Flywheel ensures outstanding decoupling over the entire rpm range.
Details
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.
