What is the basic function of a clutch?

The functions of a clutch include: 1. Facilitating gear shifting and preventing overload in the transmission system; 2. Ensuring the transfer or interruption of engine power output between the engine crankshaft and the transmission device according to the driving needs of the vehicle; 3. Assisting the vehicle in starting smoothly. The clutch is located inside the flywheel housing between the engine and the gearbox, and the clutch assembly is fixed to the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the gearbox. During driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and the gearbox, thereby cutting off or transmitting the power input from the engine to the gearbox.
The clutch, well, I've been driving manual transmission cars for over a decade, and what I know best about it is how easily it lets me control the connection between the engine and the wheels when driving in the city. For example, at a red light, I press it down, and the car stops while the engine keeps running, avoiding stalling. When the light turns green, gradually releasing the clutch transfers the engine's power to the wheels, allowing the car to start smoothly—this is especially crucial in traffic jams. If the clutch is released too quickly, the car might jerk forward; too tight, and it's prone to slipping. It's also useful when shifting gears. Neglecting regular checks, like when my clutch plate wore out, causes severe shaking during starts, demanding immediate repair to prevent getting stuck on the road. Don’t slack on routine maintenance—check the clutch fluid every 20,000 kilometers. That’s where the joy of driving a manual lies.
When I first got my driver's license, the clutch gave me the biggest headache. Its basic function is to connect or disconnect the car's engine from the drivetrain. I remember my first time on the road—the instructor said to press the clutch and slowly release it to control the start. I kept jerking the car three times because as soon as the engine disconnected, the car would stop, and when reconnected, the power would transfer to the wheels. After practicing half-clutch for a long time, I felt the car move hesitantly, avoiding the embarrassment of stalling. Later, after driving more, I realized it could be a lifesaver when starting on a slope—holding it keeps the car steady. A worn clutch squeaks, and now every time I drive, I habitually check the pedal feel. Driving a manual car requires this kind of attention.
I've been driving manual transmission for decades, and the clutch is like the lifeline of the car to me. It disengages engine power, allowing you to shift gears or stop without stalling, while also ensuring smooth starts. For example, when climbing a steep hill, pressing the clutch keeps the car stationary with the engine still running, then gradually releasing it transfers power smoothly, making the ascent effortless. In daily driving, quick gear shifts rely on it. If the clutch plate wears out, major repairs are needed. I recommend an annual inspection—don't wait until the car starts shaking during acceleration to fix it.
