ABSTRACT:
A synchronizing arrangement in a planetary gear has an axially movable ring gear which for various gearchange positions can be coupled to either of two coupling rings, situated on their respective sides of the planetary gear, via synchronizing rings which belong to these coupling rings, are capable of limited rotation relative to the ring gear and have external locking teeth to prevent gear engagement before synchronization is achieved. The ring gear is provided with two grooves which run round its inside and each accommodates a ring-shaped locking device for transferring axial force to the respective synchronizing ring at the time of gear engagement. The respective locking device is also situated in an external groove in the relating synchronizing ring and can be compressed in the radial direction.
