You do not need to press the clutch when in neutral gear. The clutch system consists of: flywheel, pressure plate, clutch disc, release bearing, release fork, clutch cable, and clutch pedal. The functions of the clutch are: 1. Gradually increase the driving force of the car to ensure a smooth start; 2. Temporarily separate the engine and transmission for gear shifting; 3. Prevent overload of the transmission system; 4. Reduce torsional vibration impact from the engine and extend the service life of transmission gears. The working principle of the clutch is: 1. When the inner race is fixed, the outer race rotates clockwise, and the wedge block does not lock, allowing the outer race to rotate freely; 2. When the outer race rotates counterclockwise, the wedge block locks, preventing the outer race from rotating.
