Claw-type gearshift and method of shifting a claw-type gearshift
In a claw-type gearshift, a blocking ring is arranged axially between a hub body having a sliding sleeve and a clutch body such that it is rotatable between a release position and two locking positions. The blocking ring is adapted to be displaced toward the clutch body until conical friction surfaces on the blocking ring and on the clutch body come into contact. The blocking ring constitutes a form-locking blockade for the sliding sleeve against displacement of the sliding sleeve teeth between the clutch body teeth when an axial shifting force is applied in the non-synchronized state. When the claw clutch is shifted, a difference in speed between the clutch body and the hub body is reduced and the sliding sleeve is deflected in the axial direction toward the speed change gear to be shifted, as a result of which a friction surface of the blocking ring and a mating friction surface of the clutch body come into contact.
