fight tooth hazards:
is actually a head-on fight tooth gear between two metal texture, the end result is obvious, that is the cause of the crown gear part accelerate wear and tear, a long time + more often, and at right angles to the original tooth was ground into a rounded crown, after bite into the block will be complete, and a little shake easily block out the phenomenon appeared, this time on the need to overhaul the shift the box.
Why fight tooth phenomenon? The reason
This has to fight tooth start talking about:
internal structure of the manual transmission has a very important device, that is, “Synchronizer.” Acting synchronizer is quite obvious that when shifting gear Since the power output of the rotational speed is faster than the immediately want to change the gear of the gear, without the synchronizer, the gear is rotated in a slowly forced into a high speed gear rotation, certainly fight tooth phenomenon occurs.
acting synchronizer is to occur at the shift operation, the gear is about to change into the gear speed to the speed of the gear and the output terminal is synchronized, so that there would not be time shift tooth hitting phenomenon .
understand that to fight tooth phenomenon, why a lot of cars traveling forward when there is no fight tooth, and a hanging reverse gear teeth hit it? That is because many models of reverse gear is not installed reverse gear synchronizer, because the concept of manufacturers, the reverse gear is engaged and then stopping it completely, and the opportunity to use a relatively small lot, so for simplicity and gearbox structure cost-saving purposes, many low-end manual gearbox is no reverse gear installed reverse gear synchronizer.
is not installed reverse gear synchronizer manual transmission will play exists engaged reverse gear teeth phenomenon. Of course, there are also user habits and has a great relationship, because the reverse gear synchronizer itself without the need to completely stop the vehicle, so that the output of the power to reduce speed and reverse gear (this time the reverse gear is stationary between the rotational speed) becomes small, so as to ensure the hanging reverse gear teeth Comparative smooth and did not play. Many users have not parked the car in a hurry to immediately linked into reverse gear, naturally make no reverse gear synchronizer very hurt, fight tooth occurs.
How to avoid the teeth play reverse:
beforeFace said, before reversing the car to a complete stop and then reverse gear is linked to one of the best ways to prevent fight tooth while, be sure to complete clutch foot in the end, must not be lazy but because half step on the clutch, which would result in serious reverse gear to fight tooth, even if there is even a forward gear synchronizer are not too superstitious synchronizer will shift very smooth, if you step on the clutch inadequately, even the best of the synchronizer also withstand great rotational speed difference, the synchronizer will wear to accelerate geometrically.
