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.

Synchronizing device for shiftable transmissions

A synchronizing arrangement for a gear transmission includes a synchronizing ring and the surrounding annular spring, the ring having at least three equally spaced support elements at the circumference of the ring at which the spring is snugly supported with a press-fit about the ring. The support elements and the spring define opposing contact surfaces which are relatively adjustable upon assembly of the annular spring about the ring in order to balance manufacturing tolerances.
