2014 Volkswagen Passat Flywheels and Flexplates

LuK conventional flywheels are dynamically balanced to reduce vibration and improve clutch performance. All new – never remanufactured – every flywheel component is engineered and built to original-equipment specifications, including the ring gear and dowel pins.

Product Features:

• OE quality and direct fit application
• Made from high quality steel
• Designed to reduce clutch chatter and vibration
• Dynamically balanced

LuK: New flywheels are a smart alternative! The flywheel is an integral part of clutch replacement. It must provide a smooth, flat surface for proper clutch operation. Pairing your clutch set with a new flywheel is a smart, cost-effective alternative to resurfacing. All new – never remanufactured – every component is engineered and manufactured to OE specifications, including ring gear and dowel pins.

Flywheel

LuK dual-mass flywheels absorb engine vibrations before they are transmitted to the driveline where they can create gear rattle. These units feature a built-in damper designed to isolate engine torque spikes and prevent transmission damage. By design, dual-mass flywheels cannot be resurfaced. This all makes the LuK dual mass flywheel the ideal solution. With one drawback: the higher the mass reactance of the vibrating masses, the more excessive the resonance increase and associated torque peaks. With the dual mass flywheel, this would be easily perceived when starting and stopping the engine; much more easily than with a conventional clutch system. Additionally: the smaller flymass of the engine has less of a stabilizing effect on the speed fluctuation of the engine. Thanks to decades of experience in clutch building, the LuK specialists were able to find an excellent solution to this problem. An additional damping device effectively prevents resonance overload. In normal operation, however, this additional damping device has no function and the torsional vibrations of the engine are filtered out by spring dampers. Friction and spring rate – the correct ratio is important. For optimal vibration isolation and soft resonance passage when starting and stopping the engine, the ratio between friction and spring rate must be optimal. The length of the springs is a key factor: The softer a spring, the more efficiently vibrations are isolated. The extra-long springs of the latest generation of dual mass flywheels significantly reduce the spring rate compared to a first generation dual mass flywheel. In routine driving operations, excessive resonance increases are kept almost completely away from the gearbox.

Product Features:

• Top driving comfort
• Absorbs vibrations
• Prevents noise
• Enables comfortable, low-revs driving
• Saves fuel
• Relieves crankshaft and gearbox

LuK: Don’t gamble – stay with the original DMF! The DMF prevents damages solid flywheels may cause. The Dual Mass Flywheel (DMF) is individually fine-tuned for every type of car. The risks of using solid flywheels are numerous – from increased wear of engine mounts through gearbox failure to damaged crankshafts.

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.

Product Features:

• 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
