&nt gearbox!

Qin Shaoyou explained the technical route, and the engineers on the scene were all staring.

They thought about it seriously.

"Qin, if this technique is used, will it cause serious setbacks?" Karl asked.

For automatic transmissions, one of the biggest problems is setbacks. In this regard, Xia Miaomiao has suffered enough, and was even forced to give up the shifting speed in pursuit of smoothness. Of course, the engineers on site are also clear. How serious is the question of frustration.


Although this kind of gearbox has not yet appeared in passenger cars, it has begun to be gradually promoted in trucks.

Mercedes-Benz was the first to eat crabs. In the 70s and [-]s, Mercedes-Benz began to explore automatic transmission solutions for trucks. They did not engage in any AT gearboxes, but aimed at their own ordinary manual gearboxes.

At the beginning, because of matching problems, this automatic transmission still had a clutch pedal, that is to say, its control system was not smart enough, and it was okay to shift gears at ordinary times, but in the initial stage, it did not have the old driver's That foot feel.

Later, with the continuous improvement of the debugging level, the clutch was completely removed. Since then, the Mercedes-Benz truck has a smart shift system and has become a high-end and high-end thing.
Especially the American-style long-headed trucks, and the long crowbar-like gearbox levers, have slowly become history.

Now that commercial vehicles can gradually mature, passenger cars are of course also fine, as long as you spend time on tuning. For a large international giant like Volkswagen, is there still a shortage of tuning personnel?

Piëch nodded: "Yes, we should try to manufacture this kind of gearbox, this kind of intelligent gearbox, and it will be one of our main projects in the future."

This guy is really easy to be fooled. However, from the current point of view, it seems that this is the most suitable solution.

"If you find it difficult to debug, you can try to add a hydraulic torque converter in front." Qin Shaoyou continued to make crooked moves.

The torque converter and the planetary gear set are the essence of the AT gearbox, but the main patents are on the planetary gear set. The torque converter can even be used in the CVT gearbox, so it is not important.
What advantage?Of course, the direct speed of shifting gears is fast and fuel-efficient! The fuel consumption of the AT gearbox is high because the torque converter is consuming energy.

Piëch nodded.

"Well, can we take a walk around your company?" Qin Shaoyou made a request.

Here, I have said a lot, I can't always let myself talk, it's time to take a walk in the workshop.

Although there are also Volkswagen's automobile factories in China, this is the base camp after all, and the two cannot be compared.

"Of course." Piëch said, "Come on, let's go to the workshop."

"Qin, what you see now is the production line of our third-generation Golf. This car is also the best-selling model of our Volkswagen in Europe." Carl walked beside Qin Shaoyou and introduced him.

Without golf, there would be no world-class public.

The first-generation golf was designed by the famous designer Giugiaro. It was originally intended to design a replacement for the Beetle. However, the designed product created a new era.

For example, this car has created the concept of a hatchback. The front suspension uses McPherson suspension, and the rear suspension is trailing arm suspension. The handling is much improved compared to the Beetle.In terms of power, it is equipped with a 1.1L engine with a maximum horsepower of only 50 horsepower.

Don't look at such a small car, which has achieved great success. When it was discontinued, it sold 680 million units, which created a miracle.

They made persistent efforts and launched the second-generation golf. Currently, the second-generation golf is mainly used for running outside. The four-eye round headlights look very dynamic.

By the time of the third generation, Giugiaro had left, and the design of this car had also undergone a lot of changes. The body lines were more rounded, and the lights also became a square with a circle.In terms of power, this generation of golf is equipped with 1.4l, 1.6l, 1.8l, 2.0l four engines, matched with a 5-speed manual gearbox.

This is also in line with the characteristics of the times. The square shape in the past has gradually been eliminated, and the rounded lines are more popular.

Now, walking through the production line, Qin Shaoyou could already see some mechanical arms in operation, some were carrying, some were welding, and Xia Miaomiao beside him had surprise in his eyes.

Although there is Santana's production line in China, it is still far from the world's first-class level!In terms of automation of the production line, the gap is even farther.

Robots used to be only in science fiction, but, with the development of technology, this technology has finally begun to appear.

In 1956, Joseph Engelberger, known as the father of robots, met with George Dave at a reception, and the two began to discuss the issue of robots. Dave said that he had just applied for a patent, It's called a "programmable device for moving objects". Isn't this a robot?

Engebojie was extremely excited, and the two hit it off and decided to cooperate to establish a company that produces robots.This is how the famous universal machine company came out.

When the machine was available, they persuaded General Motors to buy the first robot at a price below the cost price.

It was very immature at the beginning, with various failures, but later, robots gradually became common in automobile production lines. kind of it.

However, it was the people of the island country who carried forward the robots. In 1967, the island country imported the first batch of robots. In the second year, Kawasaki Heavy Industries Group obtained a production license from the universal machine company and began to manufacture and sell robots in the island country. , Soon, the quality of their robots surpassed the original robots in the United States.

In the 80s, the kimchi country also started the development of the robot industry. In 1984, Hyundai Heavy Industries established a professional robot welding team, and in 1995 developed the first hr120 spot welding arc welding robot.

As for Europe, the robot industry is also developing continuously. Their appearance has no resemblance to human beings, it is just a mechanical arm, but it has brought huge changes to the production line.

If you want to develop the automobile industry of the motherland, you have a long way to go!
