Speaking of automatic gears, there are many famous ones, such as AT gearboxes, CVT gearboxes, DSG, DCT and other dual-clutch gearboxes.

These gearboxes have their own advantages and disadvantages. For example, AT gearboxes are mature and stable, but they are more fuel-consuming. CVT gearboxes are fuel-efficient and efficient, but they cannot bear too much torque and are easy to slip. As for dual-clutch gearboxes, they are Countless people hate it and think that it is simply a disaster to human lives. However, a large number of car companies are installing because of low cost and high transmission efficiency, which means fuel saving. When car companies implement energy double integration, This kind of gearbox is helpful to car companies.

All of these have advantages and disadvantages. However, there is a gearbox that everyone hates and is considered a fool. A fake smart gearbox has serious setbacks. This is AMT.

This kind of automatic gearbox is very low-cost because its main body is a manual gearbox. It only uses a computer to replace the gear. It can be operated by hydraulic or pneumatic pressure. Any car company can make it. There is no patent trap.

However, it does not have any buffering. The clutch slams up and the gearbox slams to the gear position. If there is no frustration, it is impossible. But in the stop-and-go section of the city, this This kind of frustration is absolutely terrible. If you follow tightly, if you are afraid of bumping into it, if you follow it loosely, you will get stuck.

Any manufacturer has used their brains on this and satisfies some novices who can't use manual transmission, but in the end they are defeated because it is really unfriendly and terrible.

Of course, only the lowest automatic gear will choose it, just to lower the price.

Although this is a kind of chicken ribs, it is the only choice for heavy trucks to realize automatic transmission.

Heavy trucks have to withstand a lot of torque, so its gears are thick and thick, and the CVT steel belt simply cannot withstand it, and will collapse directly. The dual clutch requires two sets of mechanisms, and there is no such large space at all. A gearbox , Two to three hundred kilograms, if it is dual-clutch, not half a ton?

The AT gearbox is a good choice. However, this kind of gearbox needs a torque converter in front of it. The price of this thing needed by trucks is absolutely unbearable. At the same time, this hydraulic torque converter The device also requires a huge cooling system. Only large-sized cars at no cost can be used. Look at the back of the cab. There are so many equipment on your back for the heat dissipation of the torque converter.

So, in summary, this AMT gearbox developed on a manual gearbox is the only choice.

Europa has always been a pioneer in technology research and development. As early as the 1960s, some automobile companies began research on AMT technology. Daimler-Benz and Scania were the pioneers in the development of AMT transmissions. After twenty years In the 1980s, the research of the company finally became commercially available.

However, the first thing I used was not a truck, but a racing car. Yes, I mentioned DSG with Volkswagen and happily said that Porsche is also using dual-clutch. It is definitely not the price of a dual-clutch Porsche. A Volkswagen is more expensive.

The AMT gearbox can also be bragging because it is used in F1 cars.

In 1986, AMT technology was first applied to F1 Ferrari cars, which promoted a big step improvement in the performance of Ferrari cars. After that, Ferrari won many championships, and the other cars did not hesitate to change to AMT, so that the entire F1 car is all AMT.

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

Almost all trucks in Europa are equipped with this type of gearbox as standard. The driver does not need to change gears, as long as the accelerator is enough, it is absolutely worry-free operation. Of course, later, autonomous driving has begun to develop. , This kind of automatic transmission is even more needed.

The West has not yet launched any AMT products. In this era, if we launch it first, it will definitely make the whole world look at it.

"However, we don't have technical reserves in this area." Heribala said.

They have developed the engine for a long time and have technical reserves, but it is difficult to make an automatic gearbox, right?

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

It was originally based on a manual gearbox by installing a microcomputer-controlled automatic device to replace the original manual operation to complete the shifting action, and realize the automation of the entire shifting process. The most important thing is to write the program. In this regard, we are the most powerful.

"You can choose to cooperate with our Hanxin Technology Company." Qin Guan said: "I believe that everything is not a problem. We will develop rapidly in the future, and we can also provide supporting facilities for other companies."

In that parallel time and space, the country has also gradually entered the field of AMT gearboxes. Although they all claim to be independent research and development, the most important electronic control part is the purchase of WABCO's entire system. Once a trade war occurs If this supporting equipment is embargoed, it will lose the ability to manufacture such gearboxes.

Now, oneself first develops and provides support to others, that is, oneself has an advantage, and even when needed, it can sanction others. This is definitely a good feeling.

He Ribala nodded. If Hanxin Technology Co., Ltd. would provide technical support, it would be okay. Of course he would not know. There is also Qin Guan. Qin Guan pulled over from the cemetery and gave it to them to study. , Definitely get twice the result with half the effort.

"The rear axle is very simple. With a high-horsepower engine and a low-speed ratio rear axle, this is the high-speed logistics of long-distance trunk lines. Although it cannot be promoted in China for the time being, it is very popular in the world."

How fast a car can run is determined by the speed ratio. The low speed is lower than the rear axle, the speed is lower, the speed is higher, and it can run faster. The West already has a complete highway network, all of which need 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-age product!

The domestic market may be less, because this thing is too expensive, but Qin Guan is still confident when selling it internationally, even knocking on the door of Europa.

To look at the level of a country's basic industry is to look at its automobile manufacturing. The basic industry of Han must go abroad to exchange for a steady stream of precious foreign exchange for the motherland! Let Northern Heavy Truck become a world famous brand!
