System Description
DOUBLE-CONE SYNCHRONIZER
Double-cone synchronizer is adopted for 3rd gear to reduce operating force of the shift lever.
TRIPLE-CONE SYNCHRONIZER
Triple-cone synchronizer are adopted for 1st and 2nd gears to reduce operating force of the shift lever.
REVERSE GEAR NOISE PREVENTION FUNCTION (SYNCHRONIZING METHOD)
Reverse gear can be matched smoothly in a structure by setting synchronizer hub (1) of reverse idler gear (5) [Rear], reverse coupling sleeve (2), reverse baulk ring (3), and reverse insert spring (4) to reverse idler gears, and letting reverse gear be synchronized.
6 : Reverse idler gear (Front)
