2 FUNCTIONING PRINCIPLE
2.1 MAIN DESCRIPTION
The actuator (02), acting on the fork (06), moves the sliding sleeve (11) to engage either the pinion (09)
or the fixed ring (13).
When the sliding sleeve engages the pinion, the gearbox is in high speed mode (1:1).
When the sliding sleeve engages the fixed ring, the gearbox is in low speed mode (1:i).
When the sliding sleeve engages neither the pinion, nor the fixed ring, the gearbox is in neutral mode,
i.e. the output shaft is disconnected from the input shaft.
