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
