<p>The invention relates to a synchronization device, whic is provided in a range gearing with planetary gearing in a vehicle. During synchronization and gear changing, at least one spring suspensio element (28, 34, 46) transmits bearing force from the clutch sleeve to the synchronization ring by means of co-operation with first recesses (32, 33, 47, 48) in the clutch sleeve (18). Clutch sleeve, clutch rings, synchronization ring and spring suspension elements are provided on one side of the ring gear (14). The synchronization ring (24, 45) is constructed together with an additional mirror-inverted synchronization ring in order to form a double synchronization ring (24, 45) and where the clutch sleeve (18) during its axial movement for engagement of gear separates the friction surfaces (23, 36, 26, 37) in the synchronization device to the gear which becomes disengaged by means of the fact that at least one second recess (42, 43, 49) is provided on the double synchronization ring (45) and that a spring suspension element (46) co-operates with the second recess (42, 43, 49) as well.</p> |
