Understanding Clutch and Flywheel Mechanisms

Clutch

• A clutch is a mechanical part transferring power from the engine to the vehicle's transmission.
• It's crucial for smooth power transfer and gear shifting.
• Located between the engine flywheel and the transmission.

Flywheel

• A mechanical device efficiently storing rotational energy (kinetic energy).
• Stores energy proportional to the square of its rotational speed and mass.
• Resists changes in rotational speed due to inertia.
• Acts as a low-pass filter on mechanical velocity (angular).

Pilot Bearing

• Supports and centers the transmission input shaft and clutch disc.
• Allows the flywheel to maintain engine RPM while the input shaft slows down.

Clutch Disk

• Part of the vehicle's manual transmission system.
• Transfers power from the flywheel to the pressure plate.
• Usually made of durable steel, sometimes Kevlar in high-performance vehicles.

Pressure Plate

• Secured to the flywheel.
• Clamps the clutch disc during engagement, transmitting engine power to the transmission.
• Lifts away from the flywheel during disengagement, allowing for gear shifting.

Release Bearing

• Connects the rotating clutch pressure plate to the rigid release mechanism.
• Transfers release force to the clutch pressure plate using thrust ball bearings.

Clutch Fork and Connecting Linkage

• Converts clutch pedal movement into clutch throw-out bearing movement.
• Allows the pressure plate's springs to engage the clutch disc to the flywheel.

Bell Housing

• A colloquial term for the transmission portion covering the flywheel and clutch.
• Houses the clutch and associated components.
• Found in vehicles with internal combustion engines.

Clutch Master

• A component in the hydraulic clutch system.
• Acts as a pump, pushing fluid through the system when the clutch pedal is pressed.
• Transfers pressure to the clutch slave cylinder.

Clutch Slave

• Works with the clutch master cylinder to disengage the clutch.
• Receives pressure from the master cylinder and extends a rod.
• Pushing against a fork or lever disengages the clutch.
