Friedrichshafen Gear Manufacturing Co., Ltd., the name is a bit of a twist, in fact, it is ZF, the world's most famous transmission manufacturer ZF company, this company is good at the production and manufacturing of transmissions, not only used in cars, but also used in tanks.

The first model they built was codenamed the 4HP250 transmission, which was later modified to become a LSG3000 transmission, in order to bid for the transmission system of the Leopard-2 tank, but at the time of the bidding, this system lost to the HSWL354 of the RENK company, and since it was no longer needed in China, the Germans naturally marketed it as an export product.

At this time, countries around the world are also developing their own third-generation tanks, but their supporting transmission systems can not be done, so this LSG3000 system, there is a good luck that the east is not bright and the west is bright, before and after the Brazilian Engesa company's "Osorio" tank, Italy's Otto Melera and Fiat company designed C-1 tank, France's AMX40 tank, Spain's AMX30 tank and South Korea's K1 tank, all after testing, this transmission device was selected.

As the royal transmission system of a forty or fifty-ton tank, this transmission system naturally has a great background, it inherits the reliability of the 4HP250 transmission, and at the same time, new components are installed to achieve more bulls.

It features a single-stage, two-phase torque converter and a planetary shifter with multi-disc brakes that provides four forward gears. At the same time, in order to reduce the labor intensity of the operator, the automatic shift technology of the electronic control system is adopted, and at the same time, it also has a special hydraulic reducer to help the vehicle decelerate and brake.

At the same time, it has a dual differential steering system. Different steering radii can be obtained through different gears, and it can also be turned on the spot, which is an enviable ability.

In addition to these specific parameters, its biggest feature is that it is designed using the principle of building blocks. The entire drive train consists of 11 working components, each of which is individually assembled and finally assembled in a simple transmission housing.

What are the benefits? For example, it can be used not only for tanks, but also for heavy vehicles, but wheeled vehicles do not need differential steering, so it is quite convenient to remove the differential steering component.

It is precisely because of all these advantages that this transmission system has become the most suitable choice, but it is not easy to learn the technology of this transmission system.

Unless it's to import technology, but the Germans certainly don't want to.

This kind of thing can only be handed over to Qin Zhenhua to help.

"If we want to bring in this drivetrain technology at a good price, then the best solution is to have something similar ourselves." Qin Zhenhua said to Zhu Lao: "In this way, it is easy to make the other party worry in the negotiation." ”

It has been more than once, Qin Zhenhua has also mastered this law, if he doesn't have it, the West is unwilling to sell technology, just want to sell products to make money, and when he has it, that is, what he wants, if he doesn't sell it, he won't be able to sell it in the future.

"Yes, if we have our own, it would be great, but this technology is not so easy to break through." Zhu Lao said with a sigh.

At the beginning of the 122 test prototype, China planned to use the tall three-liquid scheme, what is the result? Over the years, although the technical level of all aspects of our own has been increasing, and a lot of products have been surveyed and mapped, but when it comes to their own production and research and development, there are still defects.

"Yes, it will take time, and after we introduce LSG3000, let's study it first and see how to imitate it." Qin Zhenhua said: "Although it is difficult, we don't have to worry too much, we can follow our own characteristics, the combination of East and West, just like our engine." ”

No one will improve specifically for themselves, only their own engagement, is in line with their own, their own engine, this is how it came out, when it was necessary to directly map and copy the Germans' 831 engine, Qin Zhenhua was strongly opposed, thinking that the Germans' industrial base is too high, their own imitation can not be made, as for increasing the speed to increase the power, it will bring various side effects, and they do not have the strength. New Lewen

Now, the facts have verified the correctness of Qin Zhenhua, or go his own way, on the basis of the original 12150 engine, expand the cylinder core distance, adopt advanced technology, and finally achieve this breakthrough.

In terms of gearbox, it is also necessary to follow its own characteristics, and the combination of East and West can be done.

"Yes, when it comes to our own characteristics, Xiaoyu has the most right to speak." Zhu Lao said: "The project she presided over has made a breakthrough. ”

The project hosted by Wang Xiaoyu? Qin Zhenhua turned his head to look at his wife, at this time, Wang Xiaoyu was having a calm smile on his face: "It is our laser pressing system, and the research and development of the prototype has been completed, so I want to go back to a machine factory and want to install it on a tank and test it in a real car." ”

Wang Xiaoyu came back early because of a breakthrough in the project she presided over.

At present, Wang Xiaoyu has done a lot of work, in the joint development of the Jaguar tank, Wang Xiaoyu followed the research and development and testing together, which is mainly to learn the British fire control system program, in China, there are three generations of tank fire control system research and development tasks, at the same time, there is also a laser suppression system program she put forward herself, especially the last one, Wang Xiaoyu presided over it.

At the moment, there is already a harvest.

Qin Zhenhua looked at Wang Xiaoyu's smile, and was also excited in his heart, this is a double happiness!

"Of course we can support it." Qin Zhenhua said: "Allocate an 85 tank for you to test, and you can change it as you want." ”

Qin Zhenhua is of course quite supportive of his wife, starting from this project to engage in research and development, almost a machine factory is providing research and development funds, and now, there have been results, to be loaded and tested, of course, it can also be installed on the most advanced tank of a machine factory.

At present, the most advanced of the first machine factory is naturally the 85 tank developed for Lao Ba, and it must be very exciting to put this system on it.

"No, let's put it on our 88 tank." Zhu Lao said.

If you want to say the most advanced, it should be the Type 85, as an export-oriented tank, what the user wants, what can be installed in a machine factory, what you can't produce yourself, just buy it from the international market.

And the domestic use is the 88 type tank, all parts and components, you need to be able to produce yourself, now, Zhu Lao put forward this suggestion, that is a point.

Now engaged in foreign trade, everything can be sold, but when it comes to secrets, it is still necessary to keep it, this laser suppression system is not intended to be sold, but is intended to be used as an invisible killer equipment of the army in the future!

This is the performance of this project that values Wang Xiaoyu very much!
