System Description

DOUBLE-CONE SYNCHRONIZER

Double-cone synchronizers are adopted for 1st and 2nd gears to reduce operating force of the shifter lever

1 : Outer baulk ring
2 : 2nd main gear
3 : Synchronizer cone
4 : Inner baulk ring
5 : 1st main gear
6 : 1st-2nd coupling sleeve

REVERSE GEAR NOISE PREVENTION FUNCTION (REVERSE BRAKE)


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 gear is shifted 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 gear is shifted to reverse position, 5th-reverse coupling sleeve (1) slides in the reverse direction. ()
)

5 : 5th input gear

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