Countercurrent 1982

Chapter 484 Imitation Products
In less than three days, Ruiyang sent people to fetch the materials from the BJ Department and delivered them to Duan Yun. The speed was so fast that Duan Yun felt incredible.

And this also showed Ruiyang's attitude, he was a man of his word, and his actions really gave Duan Yun a sense of urgency.

After sending the thin and tall man from the Light Industry Bureau away, Duan Yun immediately asked the people from the security department to bring the thick packets of documents on the table to his office.

There is a file cabinet in Duan Yun's office, which has been piled up to the brim, most of which are reference books and materials from the factory.

After Duan Yun asked the security department to put the seven or eight thick information bags on the desk, he closed the office door and looked at them impatiently.

Picking up one of the portfolios, Duan Yun saw that it said "Volga Automobile Factory Product Information".

Duan Yun stared blankly, then picked up other portfolios.

I saw that these portfolios were marked with the words "Gorky Automobile Factory Product Information", "Likhachev Automobile Factory Product Information", "Ulyanovsk Automobile Factory Product Information", "Moscow Automobile Factory Product Information" and so on. .

These are obviously drawings of Soviet cars.

After thinking about it for a while, Duan Yun came to his senses.

After the founding of New China, it can be said that it was a poor and blank situation, and the industrial system was even more backward and on the verge of collapse.

In the 50s, the Soviet Union’s assistance to China was not only providing funds and materials, the Soviet Union also generously provided core technology and production equipment, and selflessly dispatched a large number of experts and engineers. Complete industrial system.

It can be said that without the Soviet Union's aid to China, China's industrialization process would have been delayed by at least 30 years. This is definitely not alarmist talk.

Most of the design work and equipment manufacturing of the aided construction projects were completed by the Soviet Union, and the rest were completed by Soviet experts to help Chinese companies. A large number of Soviet scientists, engineers and technicians participated in the construction of these industrial projects, and some projects even moved entire industries from the Soviet Union. The drawings and equipment of the factory, and these drawings and equipment were in extensive use until the liberation and opening up.

And the materials in these file bags should be the drawings and materials obtained from the former Soviet Union at that time.

In the 50s, among the cars used by leading cadres, the Volga could be called the main model. At that time, senior leaders of the country all sat in this kind of car. In 1960, the predecessor of BJ Automobile Factory: BJ No. In 1960, the No. [-] Automobile Accessories Factory made a trial production of the "Dongfanghong" brand car based on the drawings of the Volga car. After that, many domestically produced cars were also made by imitating the former Soviet car products, including the current production of Duanyun Factory. The gearbox is also imitated from the gearbox of the former Soviet GAZ automobile.

China and the Soviet Union fought against each other in the early 60s. If it is only the data and drawings of that era, it will not be of high reference value to Duan Yun. After all, there are already mature imitation Soviet car production technologies in the 60s in China.

However, when Duan Yun opened the file bag of "Volga Automobile Factory Product Information" and looked through it carefully for a while, he suddenly had an unexpected surprise.

It turns out that the archives of the Ministry of Light Industry have been updated all the time. Although the relationship between China and the Soviet Union has turned bad 20 years ago, they have always maintained economic and trade exchanges. In the 70s and [-]s, many Soviet cars were imported. Many of these materials are only structural drawings of auto parts, and lack relevant technical process parameters. Obviously, they should be design drawings and materials obtained through dismantling and other methods in China at that time.

It took a whole morning for Duan Yun to go through the drawings and materials in these files, and finally put the other files in the file cabinet, leaving only the information bag of the Volga Automobile Factory.

The reason why Duan Yun specially left the information about the Volga Automobile Factory is also very simple. First, because the Volga Automobile can be said to represent the highest level of the Soviet Union’s automobile industry, and at that time the Volga Automobile was a benchmark for the Chinese automobile industry. It's because the car gearbox currently produced in the factory is also produced by imitating the GAZ car gearbox under the Volga in the 60s. If Duan Yun carries out the imitation, it has a certain technical foundation, which is better than imitating other models. The gearbox is a little easier.

Later generations have a stupid impression of Soviet products, but in fact, in the 70s, the Soviet Union was definitely regarded as the world's industrial power, but due to the limitations of the planned economy, it was unable to produce a worldwide car brand.

The decline of Soviet cars is due to the system of its planned economy and the issue of national luck, but in fact, Soviet cars before the 80s were still very advanced.

Duan Yun first screened out the main model data of the Volga Automobile Factory in the Soviet Union after the 70s, and then searched for suitable imitation car gearboxes among these models.

Duan Yun didn't go home at noon, but asked his assistant Dajun to go to the cafeteria to order a meal for him. He sat in the office and continued to look up these materials while eating.

Eventually, a transmission called the BA3-2101 model caught Cloudy's attention.

This BA3-2101 "Zhiguli" sedan is actually the "Lada" sedan well-known to Chinese people in this era.

这种轿车是1970年4月19日开始生产，而到了1973年12月的时候，已经生产了整整100万辆，到了1978年6月3日，总产量达到了400万辆。

The fact that so many cars can be produced shows that this type of car has passed the test of the market, and the engine and gearbox technology should be very mature.

Although the performance of this model in the 70s is slightly behind compared to the European, American and Japanese cars in the 80s, it is already considered advanced for the 60s car technology used by most domestic car manufacturers.

Because Ruiyang only gave Duan Yun one year, Duan Yun can't be too ambitious. Moreover, the internationally advanced European, American and Japanese cars are basically impossible to produce with domestic equipment and materials, so imitating this kind of car from the 70s The Soviet car gearbox produced by the Soviet Union became Duan Yun's best choice.

This style of Lada uses a 4-speed manual gearbox. Compared with the gearbox currently produced by Duanyun Factory, the structure is slightly more complicated, and the performance is also superior. It is better than the gearbox products commonly used in domestic commercial vehicles. Some.

In fact, Duan Yun originally wanted to imitate a hydraulic automatic transmission. The automatic transmission does not need clutches to shift gears. It has fewer gears, large changes, and stable connections. Therefore, it is easy to operate and brings a lot of convenience to the driver.

But in today's domestic auto market, due to the planned economy, ordinary citizens cannot afford cars, so there is no need to consider the convenience of drivers. In addition, hydraulic automatic transmissions are complicated in structure and difficult to repair, and they are expensive and uneconomical. The efficiency is low and the range of variable distance is limited. Although the technology is advanced, it does not meet the national conditions.

The ordinary manual gearbox has a simple structure and stable performance, and is cheap and fuel-efficient, especially the cheap price. Sophisticated manual transmission.

In addition, relying on Duan Yun's profound knowledge in mechanical technology, he can also make some small improvements to this manual gearbox to make it a real "domestic" gearbox, which can better demonstrate the technical design of his factory ability, and at the same time cater to the national pride of some Chinese...

　My friend's writing is very good, I recommend it.
