What is the correct method for operating the clutch pedal during driving tests?
1 Answers
Using the heel of the left foot as a pivot point, place the ball of the foot on the clutch pedal and utilize ankle and knee movements to depress or release it. The clutch operation process consists of the following three stages: 1. Engagement process: The diaphragm spring installed between the clutch cover and pressure plate creates pre-compression deformation, generating pressure that keeps the driving and driven components firmly pressed together—this is the engaged state; 2. Disengagement process: When depressing the clutch pedal, it moves leftward, pushing the release lever left through hydraulic cylinders, which then moves the diaphragm spring release plate left. This causes the diaphragm spring to pivot around its support pins fixed on the clutch cover, making its larger end move right while pulling the pressure plate right via the release plate; 3. Re-engagement process: Releasing the clutch pedal returns it to its original position. The re-engagement mechanism's movement reverses the disengagement process. The process concludes when the clearance between release bearing and diaphragm spring release plate reappears, and the spring recompresses the pressure plate against the driven disk—restoring power transmission functionality.
