The manual transmission has a "synchronizer". There is no synchronizer, because the gear speed of power output is faster than that of the gear that is to be changed into this gear, that is, to force a slow rotating gear to contact the speed of the gear.
The synchronizer is to prevent the gearbox from beating. The function of the synchronizer is to increase the speed of the gear to the gear speed to synchronize with the output gear speed when the shift action occurs, so that the gear shifting will not exist.
Teeth will make the crown part speed up wear and tear, the time is long, the number of times, the original right corner of the crown is worn into the round angle, after the file, the bite is not thorough, a little vibration is easy to appear the phenomenon of gear drop, finally, overhaul the gearbox.
1)倒車之前把車完全停穩(wěn)再掛倒檔是一個較好的防止打齒的辦法。
1) stopping the car completely before reversing is another best way to prevent the gear from being struck.
2) must completely step on the clutch to the end, must not be lazy and step on the half of the clutch, so it will cause a serious reverse gear, even if the forward gear of the synchronizer do not overdo the superstition synchronizer will be very smooth, if you do not step on the clutch, the good synchronizer can not bear the very good. The big speed difference makes the synchronizer wear faster.
