A synchronization apparatus for speed-changing gearing or transmissions, especially for vehicles, comprising a slotted synchronization ring arranged between a claw support and a gear shift sleeve. A blocker or blocking body supported for radially outward movement by the claw support, the blocker body engaging with play by means of an entrainment cam or dog in the slot of the aforesaid ring. The synchronization ring during the synchronization function bearing by means of one of its ends at the entrainment cam in the direction of the relative rotation to be compensated between the claw support and the gear shift sleeve. The blocker body and the synchronization ring possessing stops coacting with one another such that they can pass or travel over one another, these stops or impact means are arranged in the direction of the relative rotation to be compensated after the entrainment cam and can be brought into operable engagement with one another by radially shifting the blocker body. |
