Chapter 1726

When it comes to automatic transmission, there are many famous and familiar ones, including at gearbox, CVT gearbox, DSG, DCT and other double clutch gearboxes.

These gearboxes have their own advantages and disadvantages. For example, the at gearbox is mature and stable, but it costs more fuel. The CVT gearbox is fuel-efficient, but it can't bear too much torque and is easy to slip. As for the double clutch gearbox, countless people hate it and think it is a disaster to human life. However, a large number of car enterprises are installing it because of its low cost and, High transmission efficiency means fuel saving. When automobile enterprises implement energy double integration, this gearbox is helpful to automobile enterprises.

These have advantages and disadvantages. However, there is a gearbox that everyone hates. It is considered to be a fool. It is a fake intelligent gearbox with serious setbacks. This is AMT.

The cost of this automatic gearbox is very low, because its main body is a manual gearbox. It just uses a computer to replace gear shifting. It can be operated by hydraulic or pneumatic pressure. Any car enterprise can do it, and there is no patent trap.

However, it doesn't have any buffer. The clutch will go up with a bang, and the gearbox will connect to the gear with a bang. It's impossible to say that there is no setback, and this setback is absolutely fatal in the stop and go sections of the city. If you follow closely, you are afraid of bumping into it. If you follow loosely, you will be constantly inserted.

Any manufacturer has used their brains to satisfy some novices who can't open the manual gear, but they all lost in the end, because it's really unfriendly and terrible.

Of course, only the lowest automatic gear will be selected to drive down the price.

Although this is a chicken rib, it is the only choice to realize automatic transmission on heavy trucks.

The heavy truck has to bear a lot of torque, so its gear is thick and thick, and the CVT steel belt can't bear it at all and will collapse directly. The double clutch needs two sets of mechanisms, so there is not so much space at all. A gearbox, two or three hundred kilograms. If the double clutch, it can't weigh half a ton?

At gearbox is a good choice, but it needs a hydraulic torque converter in front of this gearbox. The price of this thing needed by trucks is absolutely unbearable. At the same time, this hydraulic torque converter also needs a huge heat dissipation system. Only large vehicles regardless of cost can be used. Look at the rear of the cab. So many equipment are used for heat dissipation of hydraulic torque converter.

Therefore, taken together, this AMT gearbox developed on the manual gearbox is the only choice.

Europe has always been a pioneer in technology research and development. As early as the 1960s, some automobile companies began the research work of AMT technology. Daimler Benz and Scania are pioneers in the research and development of AMT transmission. After 20 years of research, they finally came into business in the 1980s.

However, the first thing to use was not a truck, but a racing car. Yes, when I mentioned DSG with Volkswagen, I happily said that Porsche is also using double clutch. I absolutely don't say that the price of a Porsche double clutch is even more expensive than a Volkswagen car.

AMT gearbox can also boast, because it is used in F1 racing.

In 1986, AMT technology was applied to F1 Ferrari for the first time, which promoted the great improvement of Ferrari performance. After that, Ferrari won many championships, and other cars did not hesitate to change into AMT, so that the whole F1 car is the world of AMT.

In 1988, Iveco's trucks began to adopt this technology, and its development was slow. It began to rise gradually in the mid-1990s, and became mature and assembled on a large scale in the new millennium.

Almost all trucks in Europe are equipped with this kind of gearbox as standard. Drivers don't need to shift gears, just step on the accelerator, which is absolutely worry free operation. Of course, later, driverless began to develop, and this kind of automatic gearbox is even more needed.

The West has not launched any AMT products yet. In this era, if our own side pushes it first, it will definitely impress the whole world.

"However, we have no technical reserves in this regard," he ribala said.

The engine has been developed for a long time and has technical reserves, but I'm afraid it's difficult to make the gearbox automatic?

"I have." Qin Guan said, "it is mainly an electronic system. Don't forget, we are a powerful country in electronic system."

It is originally based on the manual gearbox, by adding an automatic device controlled by microcomputer to replace the original shift action completed by manual operation, so as to realize the automation of the whole shift process. The important thing is programming, which is the most powerful.

"You can choose to cooperate with Hanxin technology company," Qin Guan said. "I believe everything is not a problem. In the future, we can develop rapidly and provide supporting facilities for other companies."

In that parallel time and space, China also began to gradually enter the field of AMT gearbox. Although they all claim to be independent research and development, the most important electronic control parts are purchased from the complete system of webco. Once a trade war occurs and the supporting equipment is embargoed, they will lose the ability to manufacture this kind of gearbox.

Now, our own side develops first and gives support to others. That is, our side has an advantage and can sanction others when necessary. This feeling must be very cool.

He Ri Bala nodded. If Hanshin technology company came to provide technical support, it would be no problem. Of course, he wouldn't know. There is also Qin Guan. Qin Guan pulled it from the cemetery and gave it to them for research. It will definitely get twice the result with half the effort.

"The rear axle is very simple. With a high-power engine and a small speed ratio rear axle, this is the high-speed logistics of long-distance trunk lines. Although it can not be popularized in China, it is very popular in the world."

How fast a car can run is determined by the speed ratio. With a small speed ratio, the rear axle can slow down less, the speed is high, and it can run faster. In the west, there has been a perfect highway network, which needs high-speed trucks. In the west, trucks and cars run at the same speed.

In this way, a complete set of products is definitely a cross era product!

The domestic market may be less, because it is too expensive. However, Qin Guan is still confident that it can be sold internationally and even knock on the door of Europe.

To see a country's basic industrial level is to see its automobile manufacturing. The basic industry of Han country must go abroad and exchange a steady stream of valuable foreign exchange for the motherland! Let the North Heavy Truck become a world famous brand!
