Free play adjustment

Automatic freewheel selection mechanism

Due to the fact that each time the clutch is engaged and disengaged, there is a slight wear on the lining of the clutch disc, in order to maintain normal operation, it is necessary to adjust the free play, which is performed by the automatic free play selection mechanism installed at the top of the pedal. This mechanism ensures that the free play of the pedal is constant even with maximum wear on the linings on the clutch disc.

The free play is adjusted automatically by pressing and releasing the clutch pedal.

The adjustment is carried out by the gear sector, turning on the axis of the clutch pedal. The clutch cable is fixed on the gear sector, bending around it, and when the pedal is released, the cable is tensioned only by a spring. When the clutch pedal is pressed, the ratchet blocks the toothed sector, providing a rigid connection between the pedal and the sector, and the clutch cable is tensioned.

When the clutch pedal is released to its original position, the clutch cable is tensioned only by a spring. In the event of wear on the lining of the driven disk, the spring turns the toothed segment to a more distant position in relation to the position occupied before disengaging the clutch. When you press the clutch pedal again, the ratchet locks the toothed segment with a shift one tooth further, which compensates for lining wear.

The ratchet of the freewheel adjustment mechanism ensures that the gear sector can only be rotated in the direction of the clutch cable tension and ensures a constant clutch pedal travel.
