What are the main components of a clutch?

The structure of a clutch consists of four parts: the driving part, the driven part, the pressing mechanism, and the operating mechanism. The introduction to the clutch is as follows: Function of the clutch: The clutch is similar to a switch, engaging or disengaging the power transmission. The clutch mechanism allows the driving part and the driven part to temporarily separate, gradually engage, and also allows relative rotation during transmission. There must be no rigid connection between the driving part and the driven part of the clutch. Any form of automobile has a clutch device, but the forms vary. Classification of clutches: Clutches are divided into four types: electromagnetic clutches, magnetic powder clutches, friction clutches, and hydraulic clutches.
I've been driving a taxi for over a decade, dealing with the clutch on a daily basis. The key components are the flywheel, clutch disc, pressure plate, release bearing, and diaphragm spring. The flywheel connects to the engine's rotation, while the pressure plate sandwiches the clutch disc against the flywheel to transmit power. The release bearing sits behind the pressure plate—when you press the clutch pedal, it pushes against the spring to separate the pressure plate and clutch disc. The diaphragm spring acts like a flexible steel plate, capable of both clamping and quick disengagement. I've replaced these parts three times in my car, especially the clutch disc which wears thin most easily. In city traffic with frequent partial engagement, the disc wears out quickly—I recommend checking for wear every three to four years. Replacing the whole set costs around a thousand bucks.
Back when I repaired cars, I've taken apart hundreds of clutches. Its main structure consists of three parts: the driving section includes the flywheel and pressure plate, with the flywheel connected to the engine crankshaft; the driven section is the clutch disc with friction lining, responsible for power transmission; the most crucial is the operating mechanism, comprising the clutch pedal, release fork, release bearing, and hydraulic lines (older cars use cables). Nowadays, hydraulic operation is mainstream - when you press the pedal, brake fluid pushes the release bearing to work. Here's a little tip: if the clutch feels heavy when cold, it's usually due to dirty hydraulic fluid or air in the system; if engagement isn't complete when hot, check the release bearing clearance. For regular maintenance, keep an eye on the clutch fluid reservoir level - this stuff only needs changing every 20,000 kilometers.
