Do You Need to Press the Clutch When Decelerating a Manual Transmission Car?

[McReid]

When decelerating a manual transmission car, you do not need to press the clutch. However, during driving, when braking, each gear must ensure it is above the required speed; otherwise, you need to press the clutch to prevent stalling. The functions of the clutch include: 1. Gradually increasing the driving force of the car for a smooth start; 2. Temporarily separating the engine and the gearbox for shifting gears; 3. Preventing overload in the transmission system; 4. Reducing torsional vibration impacts from the engine to prolong the lifespan of transmission gears. The working principle of the clutch is: 1. When the inner ring is fixed, the outer ring can rotate freely clockwise as the wedges do not lock; 2. When the outer ring rotates counterclockwise, the wedges lock, preventing the outer ring from rotating.
