Claim 6:
7. A method of shifting a claw-type gearshift, the claw-type gearshift including a sliding sleeve adapted to be axially displaced on a hub body, a clutch body of a speed change gear, the clutch body being adapted to move into engagement with the sliding sleeve, and a blocking ring arranged axially between the hub body and the clutch body, a permanent frictional connection between a friction surface of the blocking ring and a mating friction surface of the clutch body being provided, comprising:
switching over of the blocking ring in the circumferential direction to one of two locking positions by the permanent frictional connection between the friction surface of the blocking ring and the mating friction surface of the clutch body;
reducing a difference in speed between the clutch body and the hub body;
applying a shifting force and deflecting the sliding sleeve in the axial direction toward the speed change gear to be shifted;
switching over of the blocking ring to the release position in the circumferential direction by a change in direction of the relative rotational speeds of the clutch body and the hub body, the blocking ring being entrained by the clutch body or the hub body into the release position; and
engaging the internal toothing of the sliding sleeve with the external toothing of the clutch body.
