What are the functions of a clutch?

The functions of a clutch include: 1. Gradually increasing the driving force of the vehicle to ensure smooth starting; 2. Temporarily separating the engine and transmission for gear shifting; 3. Preventing overload in the transmission system; 4. Reducing torsional vibration impacts from the engine, thereby extending the lifespan of transmission gears. The working principle of a clutch is: 1. When the inner race is fixed, the outer race can rotate freely in the clockwise direction as the wedges do not lock; 2. When the outer race rotates counterclockwise, the wedges lock, preventing the outer race from rotating. Severe clutch wear can lead to: 1. Vehicle slippage and insufficient power; 2. Difficulty in starting the vehicle or ignition problems; 3. Poor climbing performance and increased fuel consumption.
The clutch, based on my driving experience, primarily functions to connect and disconnect the engine's power to the wheels. When starting the car, pressing the clutch pedal allows for a gradual release, enabling a smooth start without stalling due to sudden jerks. During gear shifts, the clutch must be engaged to disconnect the engine's output; releasing it after shifting ensures smooth transitions without gear grinding or impact. It also serves a protective role: if the initial force is too strong or there's resistance, the clutch can buffer to prevent damage to the transmission or other components. In heavy traffic with frequent stops and starts, skilled clutch operation can significantly save fuel. On mountainous slopes, coordinating the clutch with the handbrake ensures safer starts. Common signs of clutch plate wear include slipping and weak acceleration, necessitating regular inspections and plate replacements. Though small, it's indispensable for daily driving.
The function of the clutch is quite practical. Depressing the pedal temporarily disconnects the engine from the drivetrain, allowing smooth engagement of power when starting the vehicle, preventing damage to components. During gear shifts, operating the clutch disengages engine power, enabling gear changes before re-engagement, avoiding jerks and ensuring smooth driving. Additionally, the clutch provides overload protection—like during steep hill starts—by buffering excessive throttle input to prevent transmission lock-up or overheating. Clutch issues like slipping will cause poor acceleration and increased fuel consumption, requiring prompt repair. Avoid prolonged half-clutch usage to reduce wear and extend lifespan. Overall, it ensures safe and comfortable driving, making it the core component of manual transmissions.
When I first learned to drive, the clutch was the key point. Its function is to disconnect the engine from the transmission. Pressing the pedal cuts off the power for a smooth start and prevents stalling, while slowly releasing it engages the connection to get the car moving. When shifting gears, pressing it disconnects the power, allowing smooth gear changes before releasing to prevent gear grinding and impact. It also serves as a protective mechanism, buffering sudden starts to avoid damaging mechanical parts. With a bit of practice, operating this thing becomes smooth and straightforward—simple yet practical.
