Clutch operating mechanisms include: mechanical, hydraulic, and booster types. The working principle of a clutch is: 1. When the inner race is fixed, the outer race rotates clockwise and the wedge block does not lock, allowing the outer race to rotate freely; 2. When the outer race rotates counterclockwise, the wedge block locks, preventing the outer race from rotating. The functions of a clutch are: 1. To gradually increase the driving force of the car, ensuring a smooth start; 2. To temporarily separate the engine and transmission for gear shifting; 3. To prevent overload in the transmission system; 4. To reduce torsional vibration impact from the engine, extending the lifespan of transmission gears. Severe clutch wear can lead to: 1. Car slippage and insufficient power; 2. Difficulty in starting the car or ignition; 3. Poor climbing performance and increased fuel consumption.

I've been driving manual transmission cars for over a decade and am quite familiar with clutch operating mechanisms. There are three main types: First is the mechanical linkage type, used in older vehicles - it connects the pedal to the clutch via a steel rod, requiring stiff and forceful pedal action. Second is the hydraulic type, now mainstream in modern cars, which uses brake fluid to transmit force, resulting in much lighter pedal feel. Third is the electronically assisted type seen in premium vehicles, where the pedal feels as light as pressing a button. For maintenance, regularly check for cable binding or hydraulic fluid levels. Linkage types are prone to squeaking noises, while hydraulic systems risk oil leaks affecting safety. When choosing a car, these details determine pedal comfort.

When modifying cars, I found that the type of clutch affects driving pleasure. Mechanical clutches are suitable for track racing, offering direct feedback but are tiring; hydraulic clutches are the most balanced for daily commuting, which is what my street car is equipped with; electronically controlled clutches come with auto-blip function, making downshifting exceptionally smooth. Never skimp on cheap off-brand cables when modifying your car, as they can easily snap during aggressive driving. The hydraulic booster pump requires regular replacement of specialized fluid, otherwise, the pedal becomes annoyingly soft, posing a serious danger during high-speed driving.

When I first started learning to drive, I asked the instructor how the clutch is controlled. He said there are cable-operated and hydraulic types. The cable-operated type is like a bicycle brake and requires more force to pull, while the hydraulic type is easier but prone to oil leaks. The instructor recommended beginners to choose a car with a hydraulic system, as it's easier to master the half-clutch point and is less damaging to the car. Remember to check the clutch fluid reservoir; if it's low on oil, the pedal will feel empty when pressed.
