Function of dual mass flywheel

The dual mass flywheel consists of a primary flywheel connected to the clutch disc and a secondary flywheel connected to the transmission. During engine operation, the engine generates an uneven force that is balanced by the dual-mass flywheel. When the clutch pedal is depressed, the dual-mass flywheel is disengaged and the engine can be disconnected from the transmission. When the clutch pedal is released, the dual-mass flywheel is reconnected to the clutch disc and allows the torque to be transmitted smoothly to the transmission.

The dual-mass flywheel in a motor vehicle also helps to reduce noise and vibration that occur during engine operation and load changes. This increases driving comfort and reduces wear on other components, such as the transmission.

Defects on the dual mass flywheel

The dual mass flywheel is an important component of the clutch. However, in the course of time, especially after approx. 150,000 to 200,000 kilometres, signs of wear can occur which can lead to failure.

Unfavourable engine running, such as misfiring or misfiring, can also lead to premature wear of the dual mass flywheel. Abrupt starts can also damage the dual mass flywheel. In addition, increased grinding of the clutch, e.g. due to incorrect shifting or overloading of the vehicle, can lead to overheating of the dual mass flywheel.

All in all, there are various causes that can lead to a failure of the dual mass flywheel. To prevent these, regular inspections and maintenance should be carried out to detect and rectify signs of wear at an early stage.

Why replace only the flywheel and not also the clutch?

If the dual mass flywheel of a vehicle is defective, it is often recommended to replace the clutch as well, even though it would still last many thousands of kilometres. In the case of a defective dual mass flywheel, it is often not necessary to replace the clutch. A thorough inspection of the condition of the clutch can help determine if replacement is necessary or if the clutch is still in good condition. If the clutch still has sufficient remaining life, it can continue to be used, saving additional costs.

Conclusion

Replacing the dual mass flywheel can help restore the original performance and handling of the vehicle. If the old dual mass flywheel is defective, it can cause unwanted noise, vibrations and an unsteady ride. A new flywheel can correct these problems and contribute to more driving comfort and dynamics.
