LuK DMF For easy change of the dual mass flywheel Inventor of the dual mass flywheel Classic combustion engines stimulate torsional vibrations in the drivetrain due to their power strokes and ignition sequences. Besides the downsizing trend reinforces these rotational irregularities of the engines, as the displacement size and number of cylinders are reduced in order to lower fuel consumption and CO2 emissions. This leads to increased loads for all components in the drivetrain and gearbox and therefore must be effectively damped. Over 30 years ago, Schaeffler engineers developed a revolutionary technology for damping torsional vibrations in the drivetrain under the LuK product brand: the dual mass flywheel (DMF). Unlike a conventional flywheel, the DMF consists of two masses which are mounted to rotate against each other. A damping system in the form of arc springs is integrated into the DMF. Thus, it absorbs the torsional vibrations of the engine and almost completely. Today, a DMF is already installed in every second new car and transporter – and the trend is rising! More than 125 million vehicles in Europe are already equipped with a LuK DMF today. An innovative component Schaeffler is a development partner of all well-known automobile manufacturers and the undisputed market leader in original equipment, as only very few market players can offer this highly complex damping technology. Schaeffler's experts use their development lead and continuously refine their invention. The most recent example is the DMF with centrifugal pendulum, which additionally reduces vibrations in the critical area of the drive. Defective DMF? A case for the LuK DMF For repairs, Schaeffler offers the LuK DMF, a market-leading product portfolio for independent garages and covers almost the entire European vehicle fleet. Each dual mass flywheel is individually tailored to the respective car and consists of up to 130 individual parts. Thanks to the DMF testing tool, any possible damage can also be checked and professionally assessed in the installed condition. If, in addition to the DMF, the clutch is also defective, a comprehensive composite repair with the aid of the LuK RepSet DMF is recommended. Incidentally, the Schaeffler vibration damper is available for all types of transmission – even for modern double clutch transmissions.
