Clutch

1. Clutch Disc: The clutch disc is a friction plate located between the engine’s flywheel and the transmission input shaft. It has friction lining material on both sides that can be pressed against the flywheel and pressure plate to transmit power or disengaged to interrupt power flow.
2. Flywheel: The flywheel is a heavy, circular disc mounted on the engine’s crankshaft. It provides inertia and maintains engine momentum, allowing the vehicle to operate smoothly.
3. Pressure Plate: The pressure plate is connected to the clutch cover and applies pressure on the clutch disc when engaged. It is responsible for pressing the clutch disc against the flywheel to transmit power.
4. Clutch Pedal: In manual transmission vehicles, the clutch pedal is used by the driver to engage or disengage the clutch. Pressing the pedal separates the clutch disc from the flywheel, interrupting the power flow.
5. Release Bearing (Throw-Out Bearing): The release bearing is used to engage and disengage the pressure plate from the clutch disc when the clutch pedal is depressed.
6. Clutch Linkage: In manual transmissions, a series of linkages and cables connect the clutch pedal to the pressure plate. When the pedal is pressed, these linkages transmit the force required to disengage the clutch.

The operation of a clutch involves the following steps:

1. Engaging (Clutch In):
   • The driver presses the clutch pedal, which disengages the clutch.
   • This action separates the clutch disc from the flywheel, interrupting the power flow from the engine to the transmission.
   • The driver can change gears or come to a stop without stalling the engine.
2. Disengaging (Clutch Out):
   • The driver releases the clutch pedal.
   • The pressure plate applies pressure to the clutch disc, pressing it against the flywheel.
   • This reconnects the engine’s power to the transmission, allowing the vehicle to move.
