Abstract

A synchronizing device for shiftable transmissions, comprising a synchronizer which is non-rotatably supported on a gear shaft and which comprises at least one recess for at least one thrust member. A sliding sleeve is arranged on the synchronizer and displaceable in the longitudinal direction of the gear shaft. A sliding wheel is provided for each shiftable gear, which is arranged on the gear shaft and non-rotatably connected to a coupling body. A friction element comprises at least one outer ring for each sliding wheel. An indexing element is arranged on the outer ring for defining the stop position thereof relative to the synchronizer, wherein the indexing element comprises at least one separate stop member arranged above the recess of the thrust member between the synchronizer and the outer ring.
