摘要

The synchronization device comprises an idle gear which is held in a rotating manner or added in a torque-proof manner relative to a shaft. A sliding sleeve is provided for speed alignment and torque transmission between the idle gear and the shaft which is supported in a torque-proof manner relative to a synchronizing body (4). A unit (8) has a synchronizing element (9,10) which is arranged at each synchronizer disk (6,7). The synchronizing element is extended in an axial direction (a) at a pressure piece.
