What Causes Abnormal Shaking When Slowly Releasing the Clutch in First Gear?

[DelAdam]

Reasons for car shaking when slowly releasing the clutch: Uneven pressure distribution or incorrect pressure points in the car's clutch; excessive tension in the clutch pressure spring; oil contamination or damage to the driven plate lining; bending of the main or driven plates, or inconsistent heights of the release levers. Below are relevant details about the clutch: Function of the Clutch: The clutch pedal switch ensures smooth car starting, seamless gear shifting, and prevents overload in the transmission system. The switch on the clutch pedal is normally closed. When the clutch is depressed, the switch opens, and the engine control unit receives no signal from the clutch, indicating the need to disconnect the engine linkage. This reduces the ignition advance angle and fuel injection, preparing for power reserve. Working Principle of the Clutch: The clutch's driving and driven parts transmit torque through friction between contact surfaces, using liquid as a transmission medium (hydraulic coupler), or magnetic force (electromagnetic clutch). This allows temporary separation and gradual engagement, permitting mutual rotation during transmission.
