5단 수동변속기의 후진변속장치 싱크로나이저 적용에 대한 고찰

This paper presented application of full reverse synchronizer system to the current 5 speed transmission without package change. There are three kinds of reverse shifting systems: non brake system, semi synchronizer system and full synchronizer system. The last two types, semi-synchronizer and full synchronizer systems, are used to prevent clashing and grinding noise when shifting to reverse gear. This paper explained the merits and demerits of applying full reverse synchronizer system by comparing the system with other two types of synchronizer systems, non brake and semi synchronizer systems. Components and layout of the three systems were also described. A case example of applying full synchronizer system without package impact was provided and points to be considered were suggested when applying reverse full synchronizer system.
