The basic functions of a clutch: 1. Ensure that the engine's crankshaft and transmission device can transmit or interrupt the engine's power output according to the needs of the vehicle's operation; 2. Facilitate gear shifting and prevent overload of the transmission system; 3. Enable smooth vehicle starting. The clutch is located within the flywheel housing between the engine and the gearbox, with the clutch assembly fixed to the rear plane of the flywheel by screws. The output shaft of the clutch is the input shaft of the gearbox. The engine flywheel is the driving component of the clutch, and the hub of the driven disc with friction lining is connected to the driven shaft via axial splines. The pressure spring presses the driven disc tightly against the flywheel's end face.
Last time driving my friend's manual car, I stalled three times on a hill before realizing the clutch essentially does two things: connect and disconnect. When starting off, that moment of partially lifting the clutch lets the engine and transmission gently link up, allowing the wheels to gradually turn without jerking. In traffic, pressing it with your left foot keeps the car stationary even in gear, saving you from constantly shifting to neutral. Those split-second gear changes also rely on it to cut power, or else the transmission gears would clash violently. Thinking back now, without this buffer device, manual transmissions would drive beginners crazy – even driving school cars would need gearbox repairs every other day.
