What is the function of the clutch?

Clutch The function of the clutch is to smoothly engage or temporarily disconnect the engine's power from the transmission device, facilitating the driver's operations such as starting, stopping, and shifting gears. Here are the relevant details: 1. Clutch: The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is secured to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. During driving, the driver can press or release the clutch pedal as needed to temporarily disconnect or gradually engage the engine and the transmission, thereby cutting off or transmitting the engine's power to the transmission. 2. Notes: Only manual transmission vehicles have a clutch; automatic transmission vehicles only have brakes and an accelerator, with gear shifts automatically controlled by the vehicle's computer.
I've been driving manual transmission cars for twenty years, and I feel the clutch is just there to help disconnect the engine from the gearbox. When starting off, slowly releasing the clutch allows the car to move smoothly without jerking. Pressing it down during gear shifts prevents the gears from grinding. It's most useful on mountain roads—going downhill in gear controls speed without overloading the engine. The clutch really hates being in a half-engaged state; experienced drivers know to either fully press or fully release it. Back when I drove a small truck, the clutch pedal was so heavy that my calf would cramp after a day of driving. Modern cars are much more comfortable. If the clutch ever starts slipping—when pressing the gas makes the RPMs soar but the car doesn't move—it's time to get it fixed ASAP.
