The multi-disc clutch is an essential component in vehicle transmission systems. It is used to transmit power from the engine to the gearbox and eventually to the wheels. Unlike conventional clutches, which use a single friction disc, the multi-disc clutch uses multiple friction discs to improve performance and durability.
The operation of a multi-disc clutch is based on the principle of friction. When the clutch pedal is depressed, the pressure on the friction discs is released, allowing them to separate and thus preventing power transmission. Conversely, when the clutch pedal is released, pressure is applied to the friction discs, allowing them to come together and transmit power from the engine to the gearbox.
Multi-disc clutches can experience various failures and breakdowns throughout their useful life. Some of the most common problems include excessive friction disc wear, loss of hydraulic pressure, disc warping due to overheating, and dirt and debris buildup on the discs. These problems can cause poor clutch operation, making gear shifting difficult and reducing the efficiency of the drive system.
Over the years, the multi-disc clutch has undergone significant technological advances. Manufacturers have developed new, more durable and heat-resistant friction materials, as well as electronic control systems that optimize clutch performance. In addition, hydraulic multi-disc clutches have been introduced, which use hydraulic fluid to transmit power, offering smoother gear changes and greater durability.
Below is a glossary with the most common terms related to the multi-disc clutch:
- Friction Disc: A component of the clutch that joins and separates to transmit or break power.
- Hydraulic pressure: force exerted by the hydraulic fluid to unite the friction discs.
- Overheating: excessive increase in temperature that can deform the friction discs.
- Power transmission: transfer of the power generated by the engine to the wheels of the vehicle.
The multi-disc clutch is also used in hydraulic clutches, which are transmission systems that use hydraulic fluid to transmit power. These clutches offer smoother gear shifting and increased durability compared to conventional clutches. In addition, hydraulic clutches allow more precise control of power transmission, which improves the efficiency of the transmission system.

The life of a multi-disc clutch can vary depending on the type of driving, proper maintenance and other factors. In general, it is estimated that a multi-disc clutch can last between 80,000 and 120,000 kilometers. However, it is important to note that these values are approximate and may vary from case to case.
To prolong the life of your multi-disc clutch, it is advisable to follow some proper driving and maintenance practices. Avoid pulling off jerks, aggressively changing gears, and keeping the clutch pedal depressed unnecessarily. In addition, it is important to perform regular checks on the clutch system and replace worn or damaged components on time.
The multi-disc clutch is a key component in vehicle transmission systems. Its operation, failures and evolution are important aspects to take into account to maintain a good performance of the transmission system.
