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, which includes an external toothing which has a multitude of clutch body teeth and is adapted to engage with the internal toothing of the sliding sleeve,
wherein arranged at the hub body is at least one thrust piece which is coupled to the sliding sleeve and includes a friction surface that cooperates with a mating friction surface on the clutch body,
wherein the at least one thrust piece is displaceable in relation to the hub body in a circumferential direction by a certain degree between a release position and two locking positions, the two locking positions being located on either side of the release position in the circumferential direction, and
wherein the at least one thrust piece includes a first locking structure which cooperates with a second locking structure on the internal toothing of the sliding sleeve, and the locking structures are configured such that in each of the two locking positions, the locking structures rest against each other such that a further axial movement of the sliding sleeve is blocked.
