The transmission disc, also known as a clutch disc or friction disc, engages with the transmission system to transmit power when the clutch pedal is engaged or disengaged.

---

Key Functions:

1. Power Transfer: When the clutch pedal is engaged, the transmission disc presses against the flywheel, transmitting power from the engine to the transmission system.


2. Smooth Gear Changes: The transmission disc allows for smooth engagement and disengagement of gears, facilitating seamless gear changes during operation.


3. Friction Control: The friction material on the disc provides grip and friction against the flywheel and pressure plate, allowing for controlled engagement and disengagement of the clutch.


4. Heat Dissipation: The transmission disc must effectively dissipate heat generated during operation to prevent overheating and ensure optimal performance.
