Switch gear, particularly for vehicle gearbox, has sliding sleeve and synchronizing units for synchronizing switching process, where synchronizing unit has synchronizer rings

摘要

The switch gear has sliding sleeve (10) and synchronizing units (11,12) for synchronizing a switching process. The synchronizing unit has synchronizer rings (13,14), where coupling unit (15) has an annular spring unit (16), which is provided to transfer a pre-synchronizing force from the sliding sleeve to the synchronizer rings.
