Method and arrangement for providing a synchronization device that is
provided in a range gear assembly within planetary gearing in a vehicle.
During synchronization and gear changing, at least one spring suspension
element (28, 34, 46) transmits bearing force from the clutch sleeve to the
synchronization ring by means of cooperation with first recesses (32, 33,
47, 48) in the clutch sleeve (18). The 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). 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) cooperates with the second
recess (42, 43, 49) as well.
