STRUCTURE AND OPERATION

System Description


DOUBLE-CONE SYNCHRONIZER






Double-cone synchronizers are adopted for 1st and 2nd gears to reduce operating force of the shift selector.






REVERSE GEAR NOISE PREVENTION FUNCTION (REVERSE BRAKE)

Description
Soon after the clutch is disengaged, the input shaft is still rotating due to inertia. This may cause a gear noise when the shift selector is moved to reverse position. The reverse gear noise prevention function stops the rotation of the input shaft and enables smooth gear shifting when the reverse gear is selected.
Operation Principle





1.When the shift selector is moved to reverse position, 5th-reverse coupling sleeve (1) slides in the reverse direction. (white arrow)





2.Synchronizer levers (2) with support point (A) at 5th-reverse synchronizer hub (3) presses 5th-reverse baulk ring (4). (black arrow)
3.Friction that is generated at 5-reverse baulk ring presses synchronizer lever on 5th-reverse coupling sleeve. (white arrow)
4.5th-reverse coupling sleeve that is pressed by synchronizer lever stops the rotation of input shaft.
