Chapter 352 Nanshan Gearbox
There is no impenetrable wall in the world.
Of course, the United States also heard about some of China's actions with polar bears.
Whether it was the intelligence that the United States obtained through polar bear insiders or the information obtained from China, it was all gathered at Woodcock's side.
"Smith, you can find a way to inquire and see if China is determined to use intercontinental ballistic missile launch vehicles to replace Polar Bear fighter jets."
"Then let's see if we can find out how many fighter jets China has returned in return. Are they the foreign trade version of the Polar Bears or the same version they use themselves."
Any trade in advanced weapons is not simple. Commodity trade must have complicated things behind it.
Woodcock knows this very well.
It is like the United States purchasing various military and civilian products from China and then providing assistance to the opposition in Afghanistan. This is a typical representative.
The United States is willing to sell to China advanced helicopters that it has just equipped for a few years. It also has a complicated background.
Otherwise, China would not be able to buy even the civilian version of the Black Hawk helicopter.
“From all aspects of the situation, this news should be relatively accurate, but I don’t know the specific details of the transaction.”
“If the country wants to block this transaction, I think The most important thing to do is to contact China and express our willingness to We are willing to sell F-15 or F-16.”
“Otherwise there is no way to meet the needs of relevant Chinese departments to obtain advanced fighter jets, and it will be difficult to achieve our goals.”
Smith. I can see the problem more clearly.
He also knows very well the level of China's current fighter jets.
Objectively speaking, there is still a huge gap between polar bears and the United States.
In this case, China wants to obtain advanced fighter jets. Smith can completely understand this mood and urgent practical needs.
"It's not that we are unwilling to sell advanced fighter jets to China. The key is that the price of domestic fighter jets purchased from several military industry giants is not cheap."
"Based on China's current situation The foreign exchange reserves are about 100 million US dollars, and they themselves feel reluctant to purchase a fighter jet.”
"After all, the formation of combat effectiveness cannot be accomplished by purchasing a few advanced fighter jets."
"Considering that China's existing fighter jets are all products of the polar bear style route, if we purchase our fighter jets, it will be Their entire systems are mismatched."
"So after a brief contact, the other party was not very enthusiastic."
Woodcock is obviously not optimistic about China's change. America purchases advanced things.
This is not a simple matter of buying a few products and then getting them after you buy them.
The use of fighter jets involves various maintenance and communication system issues. Unless China plans to fully switch to American military industry products in the future, it will not easily consider spending huge amounts of money to purchase them.
The most important thing is that if they are imported from polar bears, they can also be exchanged for missile launch vehicles, saving related foreign exchange to the greatest extent.
It is also very important that Polar Bear’s products will be more easily integrated into China’s own system in the future.
“This is indeed a problem, but if China and Polar Bear are allowed to trade, it will be very detrimental to us.”
“Advanced fighter jets can be traded, which shows that China and Polar Bear can trade The relationship between polar bears has greatly eased, which is not conducive to our efforts to win over China to deal with polar bears.”
Smith knows very well how the United States currently positions China.
In recent years, why has China’s international environment undergone very big changes?
Not only the United States, but also their friends' attitudes towards China have changed dramatically. This is all because the United States needs to pull China together to resist the pressure brought by polar bears.
Before 1985, polar bears put great pressure on the United States.
A few years later, the various problems within the polar bears began to become serious, and the attitude of the United States began to change.
"China is a big country, and they have their own ideas when doing things."
"Back then, their relationship with the polar bears was relatively stiff because they were unwilling to listen completely to the polar bears."
"Now I want them to It is obviously unrealistic to completely obey our words.”
“We have to find a way to make those in the country understand this.”
Woodcock feels that he does not have the confidence to hinder the polar bears. This deal with China.
In order to minimize the impact of this incident on oneself, the best way is to persuade people in the country to accept this incident, to make the people in the country realize the inevitability of this incident, and then not to care too much about the impact of this incident.
"I will sort out the relevant information to see how to make people in the country better understand this matter."
Smith can naturally understand the meaning of Woodcock's words.
On this point, his and Woodcock's interests are completely consistent.
……
"Xiaojiang, the number of our launch vehicles for export and domestic use is expected to reach about 100."
"After the delivery is completed, we basically need to consider upgrading some of the problems discovered in the past. To meet the needs of relevant departments in the next stage.”
“The operation of the current missile launch vehicle is still too complicated. Drivers can handle it more easily in places where the road conditions are better, but in places where the road conditions are better. Very complex places will test the driver’s ability.”
“We are planning to upgrade the launch vehicle to simplify the driver’s operations, and one of the key projects is to use an automatic transmission instead. The current manual transmission. ”
The development of Ligong Special Vehicle Factory this year is very smooth. Seeing that the cooperation with Polar Bear will soon come to fruition, Zhu Jiansheng immediately started working on the next technology. upgrade.
Both the United States and the Polar Bear have mastered the technology of this launch vehicle, and they have upgraded and upgraded it on this basis, eventually becoming more advanced than China.
That would be a bit embarrassing.
There are currently some domestic manufacturers that can produce gearboxes.
But the overall technical level is far from advanced.
Especially in the design of automatic transmissions, Zhu Jiansheng has no confidence in other manufacturers.
“Nanshan Technology is indeed developing automatic transmissions and has made certain progress.”
“But the design of automatic transmissions for such large vehicles is very different from the automatic transmissions on cars. The difference.”
“It’s still relatively difficult to study from scratch.”
Although he is the father-in-law, Jiang Hui will naturally not be polite when it comes to father-in-law.
The Ligong Special Vehicle Factory has now passed the most difficult period and is beginning to live a good life.
Then all related cooperation will naturally develop in the normal direction.
The large commercial vehicle transmission market is a relatively closed market. Its potential cannot be compared with that of passenger cars, but it is not very small either.
Jiang Hui doesn’t mind Nanshan Technology expanding its technology in this area in the future. “Of course I understand the difficulty.”
“After all, the gearbox on a commercial vehicle needs to withstand a lot of torque. Our kind weighs dozens of tons, and when fully loaded it reaches The gearboxes used on hundreds of tons of launch vehicles have even higher requirements in this regard.”
"The number of units of AMT gearboxes currently in use is not very large, and there is no way to fully utilize the performance of the engine. It may even stall under special circumstances."
"This situation will definitely happen in the subsequent use departments. It’s a big opinion, and we need to find a way to solve it.”
Zhu Jiansheng is an expert in the automotive industry. Although his research achievements in the field of gearboxes are not as in-depth as Jiang Hui’s, he is still among the best in the country.
Otherwise, I would not have been able to guide Jiang Hui in his graduation project of a 4MT manual transmission.
“Generally, heavy trucks are mostly diesel vehicles, and the operating speed range of diesel engines is much smaller than that of gasoline engines, about 1,000 to 2,500 rpm.”
“In order to exert maximum torque and efficiency within the vehicle speed range of 0 to 120 km/h, it is necessary to configure more gears than a gasoline engine.”
“Usually heavy trucks carry more cargo, and the higher the gears. The more pairs of engine power are used, the more effective it is!”
“In addition, when encountering different road conditions, you can also use more gears to adapt to achieve the best driving speed and output. The best matching of power output. ”
“ Another feature of having multiple gears is for fuel economy, so that the vehicle can be in the economical engine speed range at different speeds. ”
“ For example, when a heavy truck needs to start/accelerate, the torque is larger. Setting more low-speed gears can accelerate more economically and reduce the engine speed jump caused by shifting gears. ”
"For example, when the second gear reaches 2,000 rpm and the third gear is engaged, the speed suddenly drops below 1,000 rpm. Naturally, the acceleration will be weak, and if you work like this, the fuel consumption will naturally be high."
“And if a heavy truck like an intercontinental ballistic missile launcher runs on a mountainous road, it will be more fuel-efficient if it has more gears.”
“For example, on a long slope, the power of the third-speed engine will be lost. It costs a lot of money, and the engine power is not enough after shifting to fourth gear.”
“Many five-speed gearboxes have this problem. Excessive acceleration consumes fuel and the car feels uneven, so you need to increase the gear. The defect has been changed.”
“According to my calculation, in order to maximize the performance of the launch vehicle, it is estimated that the gearbox needs to have more than 20 or even 30 gears.”
< br>
"This is a very huge challenge for the design of the gear transmission structure inside the gearbox."
Of course, leaders cannot always rush to express difficult things.
At this time, Hou Guoming, the technical person in charge, will stand up and speak.
As the head of the BMW R&D Center, he now also serves as the chief engineer of Nanshan Technology.
The position will only be given up when more suitable talents come in in the future.
"Director Hou, you are right. In fact, the automatic transmission technology we need on the launch vehicle is very similar to that of heavy trucks."
"As long as you master this technology, the transmission technology in the domestic heavy truck market will be better in the future. The truck is basically yours.”
“The trucks produced by FAW and FAW are basically light trucks. , only a few manufacturers such as our Ligong Special Vehicle Factory are developing heavy trucks.”
“If you can develop a suitable gearbox for our missile launch vehicles, we will also use it on our heavy trucks. ”
Zhu Jiansheng can be regarded as binding the heavy truck gearbox project with the gearbox of the intercontinental ballistic missile launch vehicle.
Otherwise, the sales volume of gearboxes for missile launch vehicles will definitely not be very high, which will be an unprofitable thing for Nanshan Technology.
Even if the sales price is very high, selling for hundreds of thousands of yuan per unit, the R&D expenses and costs may not be recovered.
But if it is tied to the heavy truck project, the situation is different.
Amortize part of the joint development costs to the heavy truck gearbox, and at the same time share most of the production lines, the situation will be different.
The domestic demand for heavy-duty trucks is actually still huge.
Don't say too much, tens of thousands of vehicles can definitely be sold a year.
As long as the Polytechnic Special Vehicle Factory can develop heavy trucks, the supply will definitely exceed demand.
“Didn’t the Ligong Special Vehicle Factory communicate with Shaanxi Gear General Factory and Capital Gear Factory about the development of gearboxes?”
“I heard that Shaanxi Gear General Factory The factory also imported commercial vehicle gearboxes from the United States to provide supporting equipment for domestic truck customers. "
Jiang Hui is very clear about the situation of Ligong Special Vehicle Factory.
Before Nanshan Technology existed, various domestic vehicles also required the use of gearboxes.
The Hummer military vehicles and intercontinental ballistic missile launch vehicles of the Polytechnic Special Vehicle Factory are naturally no exception.
The gearbox of the Humvee military vehicle is purchased from the Capital Gear Factory. The technical level is not satisfactory and it is barely sufficient for use.
Needless to say, the missile launch vehicle, if its performance was very good, Zhu Jiansheng would not have brought his team over to talk to Nanshan Technology.
“Their technology is relatively advanced in China, but there is still a big gap between the level we want.”
"They are unlikely to have any major technological breakthroughs in a short period of time. We can't keep waiting."
"Relatively speaking, I am more confident in Nanshan Technology. You have already The 5MT manual transmission technology has been developed, and the automatic transmission technology is being studied.”
“The automatic transmission we need, among other things. In fact, it is also AMT in essence. As long as a key control component such as TCU is added to the manual transmission, it can have the same effect as an AT automatic transmission. "
"The structure can indeed be greatly improved. Simplify and reduce the difficulty of development.”
Zhu Jiansheng introduced the needs of the Ligong Special Vehicle Factory in detail.
This kind of situation where projects are delivered to your doorstep is rare in later generations.
But for many factories in this era, it is not very unusual.
My father-in-law has brought a team over to communicate, and Jiang Hui will definitely take over this task in the end.
Early communication and difficulty explanations are more about letting others in the team see the situation clearly.
Lest everyone still think that Zhu Jiansheng is using public money to enrich himself.
"We can take on this task, but the project development fee for the missile launch vehicle requires a prepayment from the Polytechnic Special Vehicle Factory. In the future, our product will only be sold to the Polytechnic Special Vehicle Factory."
The gearbox on the missile launch vehicle is destined to have no other customers.
Even if there is, it is not sold through Nanshan Technology.
So it is relatively normal for customers to pay development fees.
Anyway, the Ligong Special Vehicle Factory is not very short of money now, so there is no need for Nanshan Technology to advance everything by itself.
Of course, the specific details will definitely not be discussed at a conference like this. Instead, they will be handed over to the people below for confirmation and then submitted to the respective person in charge for approval before implementation.
Taking this opportunity, Jiang Hui also officially established Nanshan Gearbox and separated the gearbox business from Nanshan Technology.
