Shift actuator has five different types, such as sliding gears, gear sets, synchronizer, gear clutch and free wheel. And the synchronizer is widely used in automotive transmission.
This paper brings out feasibility and applicability to make change drive of double step slidinggear by moving one gear width along axis under conditions of Corresponding ratio of gear.
