Problem
The engine‘s ignition-induced rotational speed irregularity causes torsional vibration in the vehicle‘s driveline. At a given speed the ignition frequency is equal to the natural frequency of the driveline so that extremely high vibration amplitudes occur that cause transmission rattle and body boom.

Solution
In the SACHS planetary dual mass flywheel, the planetary gear and the torsional damper are incorporated into the flywheel. For this purpose, the flywheel is divided into a primary and a secondary mass, hence the name "planetary dual mass flywheel”. Rattle and booming noise are now a thing of the past.

Features & Benfits:
  • Fuel consumption is reduced, since idle speed is lowered and from idle speed the car can be driven at full throttle.
  • High level of acoustic refinement, due to the suppression of annoying rattling and body boom.
  • Good refinement even during load reversals, thanks to vibration damping. Jolts are eliminated.
  • Improved operating comfort because fewer gear shifts are required. No unpleasant booming noise that would force the driver to make gear shifts too early.
  • Improved gear shift, since lower mass moment of inertia of the clutch disc without torsional damper results in reduced shifting effort.
