The clutch is an essential component for manual transmission cars, serving to connect and disconnect the engine and transmission, allowing gear changes and vehicle control in various situations. To ensure the vehicle functions optimally, it is important to keep the clutch in good condition. This is where workshops come into play, advising drivers to have timely inspections of this part.
Beyond regular check-ups, there are factors that are shortening clutch lifespan, such as changes in engines due to anti-pollution regulations, smaller size, lower displacement, higher power, and greater efficiency. All these factors increase vibrations in the drivetrain, which reduces clutch life, according to experts.
What are the signs that the clutch is starting to fail?
For example, if the car’s engine revs too much but doesn’t gain speed, it’s a sign the clutch is slipping, caused by worn clutch disc linings, which sometimes produces a distinctive smell.
If gears engage harshly or the gear lever feels stiff when shifting in or out of gear, it indicates the clutch is not in good condition. Similarly, if the clutch pedal has minimal travel when released and the car tends to move quickly, or if strong vibrations are felt due to play, or if squealing noises occur when pressing the clutch pedal, these are signs of clutch problems.
In the clutch system, the dual-mass flywheel is one of the components that absorbs the most vibrations from modern combustion engines. Thanks to continuous technological advances in this component, other parts benefit from longer lifespans since it reduces stress on the engine and gearbox and contributes to fuel savings.
The latest technological evolution of the dual-mass flywheel includes centrifugal pendulums. This type of vibration absorber doesn’t have a fixed natural frequency; instead, it varies depending on rotational speed, allowing a 60% increase in performance compared to a dual-mass flywheel without this technology. Thus, the development of the dual-mass flywheel enables the evolution of other components in the vehicle’s transmission system, such as the clutch.
