With the rapid development of the automobile transportation industry, the manufacturing technology of the car is increasing, and the needs of the car keeping card friends are increasing. Most of the gearboxes are also from the original five speed, six speed gearbox, also unknowingly upgrade to nine speed, ten speed, twelve speed and sixteen speed, or even higher, even stepless speed change.

Today, I would like to discuss with you a little experience in the maintenance and repair of automotive gearboxes.

Take the most widely assembled twelve speed gearbox in the market, when the manufacturer comes out, most of the main boxes are equipped with synchronizer. Because of the long running and the torque of large horsepower, and the improper use of overload and overload, and no more gear oil in some years, it is very easy to cause transmission. The damage of the synchronizer and gear in the box.

According to the normal usage rule, gear oil should be changed about fifty thousand kilometers per eighty thousand kilometers. I personally recommend that the gear oil be replaced every year, and that it should be consistent with the climate temperature conditions of the local climate, or to meet the climate temperature conditions of the places where they often run. It's cold in the north and difficult to start cold in winter. 90 of the gear oil is used. The hot weather in the South can consider 140 of the gear oil.

Of course, a good car can not avoid damage because of various objective reasons. In the process of maintenance, we must pay attention to the gap between the adjusting pads of the V3 parts of the north of Baotou, because the two axis gears are all suspended teeth, (unlike the previous one, a two axis, so simple), the gap between each gear and the adjustment pad should be kept in the 0.2—-0.4mm, the gap should be kept in the gap. After the meeting, the meeting causes the individual gear to drop, or the adjustment pad break. Conversely, the gap is too small or there is no clearance, and the lubrication is not in place, which causes the burning of the adjustment pad and the two axis long key, which leads to the string position of the gear son, and may also cause the tooth beating, or the gear position can not be removed.

It is also the North V3 accessory box, that is, the high and low gear in the process of operation, remember, remember, the downhill do not skid skiing, because the gearbox gear lubrication is splash lubrication, engine idle running with the lubricating oil, far from the lubrication requirements of high speed skidding.

When the car is driving at high speed, it must not turn the high and low hand ball into the low speed area, which is very easy to cause the excessive wear of the high and low gear synchronizer of the V3 parts of the North running, or the low speed ring, break the leg, and then hang the low speed area without aisle.
