<p>A synchronizing arrangement in a planetary gear (1) has an axially movable ring gear (22) which for various gearchange positions can be coupled to either of two coupling rings (9, 16), situated on their respective sides of the planetary gear (1), via synchronising rings (14, 20) which belong to these coupling rings, are capable of limited rotation relative to the ring gear and have external locking teeth (30, 31) to prevent gear engagement before synchronisation is achieved. The ring gear (22) is provided with two grooves (26, 27) which run round its inside and each accommodate a ring-shaped locking device (28) for transferring axial force to the respective synchronising ring at the time of gear engagement. The respective locking device is also situated in an external groove (32, 33) in the relating synchronising ring and can be compressed in the radial direction.</p> |
