What is the main function of a clutch?

The main functions of a clutch: 1. Ensure smooth vehicle starting; 2. Achieve smooth gear shifting; 3. Prevent overload of the transmission system. The clutch is installed between the engine and the transmission, serving as the assembly component in the vehicle's transmission system that directly connects to the engine. Typically, the clutch is mounted together with the engine crankshaft's flywheel assembly, acting as the component that cuts off and transmits power between the engine and the vehicle's transmission system. After the engine starts and before the vehicle begins to move, the driver first presses the clutch pedal to disengage the clutch, separating the engine from the transmission system, then engages the gear in the transmission, and gradually releases the clutch pedal to allow the clutch to gradually engage. As the clutch engagement tightness progressively increases, the torque transmitted from the engine through the transmission system to the drive wheels gradually increases. When the traction force is sufficient to overcome the starting resistance, the vehicle begins to move from a standstill and gradually accelerates.
Friends who drive manual transmission cars all know that the clutch is something the left foot deals with all day. Simply put, when you press the clutch pedal, it temporarily disconnects the engine from the transmission. This way, when you shift gears or stop, the engine won't suddenly stall or cause the gears to clash. Especially when starting at a traffic light, it allows the engine's power to be smoothly transferred to the wheels without jerking. My ten years of experience driving manual transmission tells me that when the clutch plate wears out, the car will slip, and when climbing a hill, it will roar but won't move. Usually, you need to be careful not to drive with the clutch pressed all the time, otherwise, you'll have to replace the clutch plate every 20,000 kilometers. It's like a bridge worker—connecting firmly when needed and disconnecting cleanly when required.
