Synchronization device for gear box of motor vehicle e.g. passenger car, has synchronizing unit that is formed, such that pre-synchronization of synchronizing unit is realized by spring tongue portion

摘要

#CMT# #/CMT# The device (1) has a synchronous portion (2) which is provided with aligned external gears. A sliding sleeve (3) is provided with internal gears which are engaged with external gears. A synchronizing unit (4) is provided with check gearing (4d) which is engaged with gearing portion of ratchet wheel (5). The sliding sleeve is contacted with cone region (4a) and synchronizing unit is formed, such that pre-synchronization of synchronizing unit is realized by spring tongue portion. #CMT#USE : #/CMT# Synchronization device for gear box of motor vehicle e.g. passenger car. #CMT#ADVANTAGE : #/CMT# The assembling and manufacturing of synchronization device can be simplified. The maintenance cost of the synchronization device can be reduced. The wear characteristics of the synchronization device can be improved. The stability of the synchronization device can be improved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of the synchronization device. 1 : Synchronization device 2 : Synchronous portion 3 : Sliding sleeve 4 : Synchronizing unit 4a : Cone region 4d : Check gearing 5 : Ratchet wheel.
