Clutch discs
Clutch discs are key elements of the clutch system in vehicles equipped with drive mechanisms.
What are clutch discs?
Clutch discs are clutch components that ensure the transfer of torque from the engine shaft to the gearbox or other vehicle drive mechanisms. They are located between the clutch pressure plates and are directly related to the clutch mechanism.
Construction of clutch discs:
- Material: Clutch discs are typically made of high-carbon steel or composites that provide high compressive and frictional strength.
- Disc: This is the element on which the clutch disc linings are mounted. The disc can be single-sided (lining on one side) or double-sided (lining on both sides).
- Clutch disc lining: This is a layer of material with a high coefficient of friction that allows the transmission of torque. Cladding can be made of various materials such as Kevlar, ceramics, metal or composites.
Operation of clutch discs:
When the engine is running, the clutch discs are pressed against the pressure plates by a hydraulic, spring or piston mechanism. When the clutch pedal is depressed, the clutch discs are separated from the pressure plates, which interrupts the transmission of torque to the gearbox. When the clutch pedal is released, the clutch discs are pressed against the pressure plates, allowing for smooth gear shifting.
Clutch disc maintenance and replacement:
- Regular inspection: It is worth regularly checking the condition of clutch discs for wear of the linings and their thicker layers.
- Replacement: Worn or damaged clutch discs should be replaced according to the vehicle manufacturer's recommendations to ensure safe and effective operation of the clutch system.
