In later generations, there are a lot of manpower supporting cvt, because this kind of gearbox has no gear transmission and can truly achieve continuously variable transmission. In theory, there is no setback in shifting gears.

Although there is no gear position, the engineer chose several commonly used speed ratios as the position of the gear position when calibrating, so as to compete with other gearboxes.

If you want to talk about smoothness, you have to slow down your feet. When driving a car with a cvt gearbox, you must not be impatient. It is quite smooth. If you are in a hurry, the steel belt will slip. If there are too many, the steel belt may break at any time.

Generally speaking, cvt will not match turbocharged models, because the power output of this engine is too irritable, and it cannot match the soft gearbox.

In the past, Audi used a self-priming engine to match their cvt without any problems, but now, if you want to overcharge the turbocharged engine, then the problem will come.

It doesn't match at all!

When Qin Shaoyou said this, everyone present became serious.

Qin Shaoyou is right, this is indeed a big problem!

How to match?

In the future, their Audis can't always use a manual gearbox, can they?That's so cheap.

"Qin Gong, tell me, what gearbox will we match in the future?" Piëch asked.

Qin Shaoyou shook his head: "I don't know."

In fact, Qin Shaoyou is already talking too much after saying this. The crisis of the public is Qin Shaoyou's opportunity. Why remind them?

It's not easy to switch roles back and forth between engineer and businessman!

"If we can't produce it ourselves, we can only purchase it." An engineer said: "There are not many models that can meet our requirements. If you want to avoid competition, the Aisin gearbox of the island country is good. "

Piëch shook his head: "The automatic transmission is very important, we can't let others get stuck in our necks."

Qin Shaoyou still admires this man at the helm very much. What he said now is very far-sighted.

If you can't produce it yourself and can only buy it out, it's easy to get stuck.

but,

They want to produce it themselves, and there is no other way. After all, they vigorously develop dual-clutch, which was developed from Porsche's PDK gearbox. Now, the relationship between Porsche and Volkswagen is very delicate.

Porsche went smoothly. At one time, it wanted to acquire Volkswagen, or hold a controlling stake in Volkswagen. At first, the preparations were almost done. It bought a large number of Volkswagen stocks in the market, and when it was the last trembling, it caught up with the financial crisis and Porsche had no money. After repaying a lot of debts, it was bought by the public instead.

There are very few roads ahead of Volkswagen.

"We bought Aisin's patent." Who would have thought that Piëch would say such a thing: "We directly produce their AT gearboxes."

It was only then that Qin Shaoyou realized that it was still difficult for the public to open up a road on their own. All they could think of was to directly purchase patents for production.

In later generations, countless people boasted how good and how high-end AT is, but they found a speechless scene. Volkswagen uses AT for low-end cars, and dual-clutch for high-end cars. Who is the high-end?If you actually use it to experience it, you can find that at is not as good as dual-clutch.

This is of course because this is an AT gearbox authorized by Volkswagen, which costs less, but the first-generation Aisin 6AT, which is very poor, and it still frustrates or something.Now, under the urging of Qin Shaoyou, Piëch is about to make such a decision, and he is also a very courageous person.

After all, they don't seem to have much choice.

AT is blocked by the patent, the torque of the cvt is not big enough, the manual transmission is not high enough, dual clutch?That's racing stuff, no one has thought of using it in a family car yet.

If the public doesn't do it now, then it won't do it in the future. Qin Shaoyou will directly support them.

Qin Shaoyou thought secretly in his heart, suddenly, he remembered something again, and his eyes lit up.

"Actually, if you want to complete the development of automatic transmission at low cost, I have an idea."

This sentence immediately attracted everyone's attention.

"what idea?"

"On the basis of our existing manual transmission, add a set of shifting mechanisms, so that the function of automatic transmission can be realized."

Qin Shaoyou threw out this set of the most unpopular automatic transmission, and fooled Volkswagen. If they are not fooled, then it is a joke.

All kinds of automatic transmissions have advantages and disadvantages. AT is mature and smooth, but fuel-intensive. CVT can save fuel, but it can’t be violent. Dual-clutch, it can speed up so fast that it can fly and save fuel, but urban traffic jams stop and stop. will overheat the clutch.

According to your own needs, choose a gearbox that suits you, but there is one that you absolutely cannot choose, it is absolutely cheating, and there is no benefit.

That is the amt gearbox.

This kind of gearbox is composed of adding a set of electronic control units on the basis of ordinary manual gearboxes. The cost of modification is very low, which can greatly lower the price of automatic gearboxes. Believe me 6at, the factory purchase price of that thing in large quantities is more than 8000, but if you get this kind of amt, it may be one or two thousand.

Therefore, many car companies aimed at cheapness and installed this kind of gearbox on the car. The result?

No one will like it, it's frustrating, fuel-consuming, not smart, it's better than a manual transmission!Anyone who installs this kind of gearbox will have to change it back before long.

Can't stand it at all.

In fact, this kind of gearbox can still play a role in a certain field, that is, heavy trucks.

In later generations, when heavy trucks gradually began to popularize automatic transmissions, AT was rarely used, and most of them used AMT. After all, the original transmissions of heavy trucks were very large. It was difficult and fuel-intensive to use AT. .

This kind of automatic gearbox can also be used after it matures slowly, after all, it saves the left leg.

Later, this kind of amt gradually became popular. For old drivers with rich driving experience, it is still good to make do with it. Control the accelerator with your feet, and you can know when to upshift and downshift.However, the driver of a passenger car can't do it!

Look at those novices who came out of the driving school, which one can be proficient enough to change gears without stepping on the clutch?

With their driving skills, operating an amt gearbox is a disaster.

Need to speed up, just step on the gas pedal slowly and flicker up, and the result?Push down on the accelerator, well, the engine bangs, the gearbox quickly downshifts, the power is temporarily interrupted, a setback, and then the engine explodes, the instant sense of speed up makes the blood spurt, so let go quickly, so the engine and The transmission is back to its unintelligent programming.

Dual-clutch is somewhat similar, and this situation will also occur, but after all, dual-clutch has two sets of power transmission routes, and there are few power interruptions. There is only one set of ordinary manual gearboxes. Therefore, if you can’t master the trick, it will be like driving roller coaster.
