The SACHS planetary dual mass flywheel incorporates the planetary gear and the torsional damper 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.

SACHS planetary DMF: The advantages for the driver

• • 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.

  Features and Benefits:

  • Excellent vibrations damping quality through all engine-speed.
  • Effortless engine start, short start and stop behavior.
  • Good tuning capability thanks to springs in series and spring sets with various stiffness ratings, guided by plastic sliding blocks and spring caps, which keeps the springs from going solid.
  • Planet gears increase the dynamic mass moment of inertia.
  • Grease-filled for long service life.
  • Combination of three mechanisms with damping effect:
  • friction (friction bearings, centrifugal force)
  • vibration damping proportional to speed
  • inertia of planetary gear
  • no special friction device needed
