Claim 0:
1. A claw-type gearshift, comprising:
a sliding sleeve which is adapted to be axially displaced on a hub body and includes an internal toothing having a multitude of sliding sleeve teeth, and a clutch body of a speed change gear, the clutch body including an external toothing which has a multitude of clutch body teeth and is adapted to engage in the internal toothing of the sliding sleeve, and
a blocking ring which has an external toothing and is arranged axially between the hub body and the clutch body and which is fixed to the hub body such that the blocking ring is rotatable in relation to the sliding sleeve by a certain degree in the circumferential direction between a release position and two locking positions, the locking positions being located on either side of the release position in the circumferential direction,
wherein the blocking ring includes a plurality of axially resilient tabs which are directed radially inward and which bear against the hub body and limit the movement of the blocking ring relative to the hub body in the circumferential direction, and a ring portion which is arranged radially outside of the tabs and which includes a friction surface that rests permanently against a mating friction surface on the clutch body, wherein a permanent frictional force acting between the ring portion of the blocking ring and the clutch body is adjustable by an angle and a length of the axially resilient tabs.
