What is the free travel of the clutch?
1 Answers
Clutch pedal free travel refers to the reflection of the gap between the inner end of the clutch diaphragm spring and the release bearing on the clutch pedal. For example, the free travel of the clutch pedal in a Santana sedan is 15-25mm. Below are relevant details about clutch free travel: 1. If the pedal has no free travel, meaning the release bearing remains in contact with the inner end of the diaphragm spring when the clutch pedal is released in the engaged state, this will accelerate the wear of the release bearing. 2. If the diaphragm spring is pushed by the release bearing, it will cause the clutch to slip when transmitting engine torque. 3. If the pedal free travel is too large, the distance the release bearing pushes the diaphragm spring forward is reduced, and the distance the pressure plate moves backward is also shortened. This prevents complete release of the pressure plate's force on the driven plate, resulting in incomplete clutch disengagement and making gear shifting difficult.
