A glance at the benefits of the Luk dual mass flywheel
- Top driving comfort
- Absorbs vibrations
- Prevents noise
- Enables comfortable, low-revs driving
- Saves fuel
- Relieves crankshaft and gearbox
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 stabilising 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.
Modern engines can be driven at extremely low rpms. The trend is toward ever increasing engine torques. Wind-tunnel-optimized bodies are creating less wind noise. New calculation methods are helping reduce vehicle weights and weight-saving concepts are boosting engine efficiency as well. The addition of a fifth or a sixth gear can also reduce fuel consumption. Thinner oils are making precise shifting easier. In short: The sources of noise are increasing and natural damping is decreasing. What has remained is the principle of the internal combustion engine whose cyclical combustion processes excite torsional vibrations in the drive train – the unpleasant consequences of which are gear rattles and body booms.
Drivers who are accustomed to increased comfort no longer accept such background noises. The job of the clutch is now more important than ever – in addition to engaging and disengaging, it must effectively insulate the engine's vibrations. Physically, this is easy to solve: The mass moment of inertia of the transmission must be increased without increasing the mass to be shifted. This dampens the engine's torsional vibrations and brings about the desired comfort level. The process reduces load on the transmission at the same time.
It's all in the name
LuK was the first manufacturer in Europe to develop and sell a dual-mass flywheel in large-scale standard production that was able to realize this physical principle. The name says it all: The mass of the conventional flywheel was simply split in two. One part continues to belong to the engine's mass moment of inertia, while the other part now increases the mass moment of inertia of the transmission. The two decoupled masses are linked by a spring/damping system. One clutch disc, without a torsion damper, between the secondary mass and the transmission handles the engaging and disengaging functions. A favorable side effect is that the transmission is easier to shift because of the low mass to be synchronized, and there is less synchronization wear.
The clutch disc is the clutch's central connection element.
In combination with the clutch pressure plate, it both separates and links engine and powertrain. It also reduces the speed fluctuations in the gearbox caused by the combustion motor. LuK offers the best solutions for every application, from clutch discs with simple torsion damper through to variants with multi-stage dampers, from rigid clutch discs for use in the dual mass flywheel right through to the displacement correction clutch disc.
Combustion engines have a problem: They provide a usable output only in a very specific speed range – just the opposite to electric or steam engines. This means that speed, transferable engine output and gearbox must be optimally synchronised in various drive conditions – this function is provided by the clutch. The clutch separates or connects powertrain from and to the gearbox, which every driver knows from his own experience. When the clutch pedal is depressed, this powertrain is interrupted and a different gear can be engaged. The clutch also enables cars, trucks and other utility vehicles to accelerate away smoothly and without engine bucking.

LUK OE Quality clutch kit
The product was shipped promptly. Good communication.
Great clutch kit way better than stock
I got my SVT drove it for 10 minutes and the clutch went out. Came here and bought this LUK clutch and is making me very happy it can even handle my jackson racing supercharger with all its power and can handle autocross and track days. I would buy again.
