The invention relates to a synchronization device (2) for torque-transmitting components (4, 6, 8) of a transmission comprising a disk set (40) which has several disks (82) and a synchronizer sleeve (30) connected to a shifting device (64). The synchronizer system (2) has mechanisms (82, 84, 86, 88, 90, 92, 94) that divide the torque among the torque transmitting components (4, 6, 8) into an initial lower torque and a subsequent larger synchronizing torque. This is preferably achieved by a gradation of the disk (82) that enables a successive engagement of the disks on the torque transmission.
