Abstract

A claw-type gearshift includes a sliding sleeve and a clutch body of a speed change gear, in which the sliding sleeve can engage. A blocking ring having an external toothing is arranged axially between the hub body and the clutch body and is fixed to the hub body such that it 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 blocking ring has 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.
