A multi-plate clutch is a type of clutch that uses multiple friction plates to engage and disengage power between the engine and transmission in vehicles. This design allows for a larger surface area, which improves torque capacity and reduces the overall size of the clutch. Multi-plate clutches are commonly found in high-performance vehicles and motorcycles, where efficient power transfer is crucial. These clutches operate by pressing the plates together using a spring mechanism, which creates friction to transmit power. When the clutch pedal is pressed, the plates are separated, allowing the engine to run independently of the transmission. This mechanism is essential for smooth gear shifting and overall vehicle performance.
