Not all manual gears are the same minute minute church control ZF manual 16 files

In recent years, in the stalls of the “National Six” emission upgrade, various car companies have also begun to comprehensively upgrade the entire vehicle. The gearbox is also undergoing a series of upgrades and changes, more and more gears, and more and more precise control. ZF (ZF) is one of the most common gearbox brands. Before the China Truck Network summarized the standard operation of the ZFTraXon automatic 12-speed gearbox (http://), let's talk about the ZF Eco4 manual 16-speed shift. The standard operation of the box.

How to understand 1L/1H, 2L/2H... on the handle?

I believe that many old drivers will think that the 16th gear is an upgraded 12-speed gear. As long as the gearshift logic of 12 gears is extended: after the 6th gear is hung in the resisting zone, the high and low gear switches are dialed up, and then 7/8/9/ 10...just fine. In fact, this shifting operation is very troublesome. When starting from the first gear to the 16th gear, it is necessary to complete 16 shifting operations. This operation intensity is very large.

In fact, the ZF16 gearbox is simpler to operate. It is equivalent to an 8-speed gearbox. On the basis of this 8-speed gear, there are 2 half gears in each gear position (for example: 1 gear is divided into 1H gear and 1L gear, the rest) The gear position is like this. 8X2=16, 16 is the way. (That is, 1L is equivalent to 1st gear, 1H is equivalent to 2nd gear, 2L is equivalent to 3rd gear, 8L is equivalent to 15th gear, and 8H is equivalent to 16th gear)

2 half files on each individual gear based on 8 gears

There is a “pre-selected valve” below the shift lever of the ZF Eco4 manual 16-speed gearbox, and the up-and-down “high half” mode is the “low half” mode.

How to shift gears normally? How to use "pre-selection valve"?

The shifting mode of the ZF Eco4 manual 16-speed gearbox is the same as that of the ordinary 8-speed gearbox. When shifting gears, the clutch pedal is deeply depressed and the brake pedal is slowly depressed to protect the synchronizer. In order to change to the required gear as soon as possible, you can directly raise or lower a full gear, but not more than 2 full gears.

4H to 4L gear

If you need precise control of the gear, you can change the half gear through the preselection valve. When you need to reduce the gear from 4H gear (8 gears) to 4L (7 gears), push the pre-select valve downwards, press the clutch, and then relax the clutch to successfully reduce the half gear.

4L to 3H gear

If you need to reduce the gear from 4L (7-speed) to 3H (6-speed), push the pre-select valve up, press the clutch, and then move the lever from 4L (7-speed) to neutral and then to 3H. Block (6th gear), you can successfully reduce the half gear, otherwise the operation can complete the half gear.

In short, there is no need to operate the “pre-selected valve” when shifting gears. When the gear is accurately controlled, the “pre-selected valve” needs to be operated. When the “L-half” is raised to the “H half-speed”, the “pre-selected valve” is pushed up. When the "H half gear" is lowered to the "L half gear", the "preselected valve" is turned downward.

What should I pay attention to in daily operation?

Shift shifting is also a situation often encountered by old drivers. For ZF Eco4 manual 16-speed gearbox, it can be used for skipping, but only one gear can be jumped. For example, 4L/H can jump 6L directly. /H file, but can not jump 7L / H file, it will damage the gearbox.

In addition, it should be noted that when the vehicle speed is higher than 28km/h, it is forbidden to switch from the high speed gear to the low speed gear, otherwise the synchronizer will be damaged.

Neutral taxiing increases accident rate

Like all gearboxes currently on the market, neutral slip does not reduce fuel consumption, so do not use neutral gear to slide in long downhill conditions, but increase the probability of accidents. The drive shaft should also be removed when the trailer is in use. Otherwise, the transmission cannot be dissipated due to the lack of lubrication of the transmission system.

I have seen the above and I believe that everyone understands the basic operation of this gearbox, but it is not very complicated. However, there are many things to be aware of. The separation and separation of the clutch, the soft operation, the attention to the speed of the car, etc. are all important for every driver to drive each car. Developing good driving habits is also an effective way to extend the life of the vehicle.
