Chapter 1047 The Power of a Veteran Manufacturer

Faced with such a project that may earn hundreds of millions of dollars in the next few years, the military industry department of the entire Sinotruk Group began to run at full speed. The publicity materials of the South African RG-31 mine-resistant vehicle were found out, and the American M1114 The publicity materials of the "Super Hummer" were found, and the publicity materials of the ongoing "Puma" and "Buffalo" mine-resistant vehicles in the United States were also found. The noise became a pot of porridge...

"The ground clearance must be improved a little more. A higher ground clearance helps to reduce the impact of the shock wave generated by the explosion on the car body and the car body. The existing ground clearance of 2300 and 2150 is still a little bit worse. If you can use the door It would be even better with a single axle.”

"The portal axle is not a big problem. Mercedes' portal axle patent has expired a long time ago, but we don't have experience in the development of portal axles here. If we have enough time, we can proceed slowly. Technical verification, but what we lack most now is time..."

Hearing the problem of the portal axle, Cai Xiangdong, who personally sat in the R&D department and listened to everyone's opinions, asked Zhang Qihang: "Mr. Zhang, what do you think about the problem of the portal axle?"

Zhang Qihang pondered for a while, cleared his throat, and said, "Comrades, let me share my views on the portal axle. There is no doubt that the portal axle is a good thing, and it can at least increase the ground clearance of the chassis by 10." Centimeters, or even more, but as Li Gong said, even if Mercedes-Benz's portal axle patent has expired, we can take it over and use it, but we don't have the experience in R&D and manufacturing of portal axles.

Although the portal axle is theoretically adding a gear, but only one side has such an extra size, the entire axle needs to undergo a whole set of technical verification, which takes time, and what we lack the most is time... ...We must come up with two mine-resistant vehicles based on the chassis of the two trucks 2151 and 2300 within half a year.

So my opinion is that the first car of our group should use the chassis of the 2151 and 2300 trucks as much as possible. Except for a slight chassis lift, the rest of the place should be kept as still as possible to ensure that the product can be delivered as soon as possible. Bring to market. "

After Zhang Qihang finished speaking, someone immediately said: "If this is the case, then the problem is not big, but Mr. Zhang, I have read these materials, whether it is the RG-31 in South Africa or the "Puma" that the United States is currently engaged in. and 'Buffalo', they are long cars with the engine compartment in front.

The advantage of this solution is obvious. The engine can provide additional protection for the occupants of the car as much as possible. Compared with RG-31, 'Puma' and 'Buffalo', our 2151 trucks and 2300 trucks are flat-top trucks , the engine and gearbox are under the passenger compartment, this..."

"Sun Gong, everything has advantages and disadvantages, and there is no one solution that can take into account all aspects," Zhang Qihang said with a smile: "The long-terminal solution is of course good, and it can provide positive benefits for the occupants, especially the drivers. The front has the best protection performance, but the long-headed car is not without disadvantages, and our flat-topped car is not without advantages.

The engine and gearbox of our flat-top car are under the car, and this arrangement can provide good protection for the car under the car, right?After all, roadside Z bombs are generally placed on the side of the road in advance, and usually explode under the side of the vehicle. This type of explosion has a greater impact on the side and bottom of the vehicle body, but has no effect on the position of the front of the vehicle. , From this point of view, there is no need to use an engine as a shield at the front of the car.

Of course, if the user does have requirements for the protection of the front of the car, that is not a problem. Ask the customer what level of protection they need to provide. We can hang armor plates or even composite armor directly in front, as long as the customer is willing to pay. "

Sun Gong thought for a while, then nodded in approval: "That's the truth."

Seeing the RG-31 in South Africa, Sun Gong subconsciously felt that the overall layout plan of RG-31 was the most reasonable, but now he heard what Zhang Qihang said, and he also felt that what Zhang Qihang said was right: since the main danger to deal with is Roadside Z bombs, it is actually a good thing for the engine and gearbox to be under the car. If the user has a requirement to strengthen the protection of the front of the car, then install more armor plates.

"In addition, it is the bottom structure and seats. The bottom structure of the RG-31 is a V-shaped bottom. According to the public information, this V-shaped bottom can effectively deflect the shock wave generated during the explosion... "Speaking of this, Zhang Qihang looked at the crowd and said: "It is true in theory, but how to determine the appropriate value of the V-shaped angle and how to give the most appropriate thickness of the car body will be difficult for everyone."

Again, there are advantages and disadvantages in everything. The structure of the V-shaped car bottom can effectively penetrate the shock waves generated during the explosion, but this requires sufficient ground clearance and a sufficiently ideal V-shaped angle value, and the V-shaped vehicle The closer the angle value is to 90 degrees, the better, but the defect of the V-shaped bottom is also obvious, that is, when the height of the vehicle from the ground is too high, its maneuverability will deteriorate.

Everyone naturally nodded.

In the ensuing discussion, someone suggested: "In addition to adopting a V-shaped bottom and strengthening the armor protection of the body armor and chassis, the South African RG-31 also uses impact-resistant seats similar to helicopters. I think this The configuration should also be there."

The impact-resistant seat is a unique seat for helicopters. How to ensure the safety of the driver and passengers after the helicopter engine fails?Helicopter designers took three approaches:
First of all, the falling speed of the helicopter is reduced by the passive spin of the main rotor, instead of falling from the sky like an iron bump. With the help of the passive spin of the main rotor to slow down, the falling speed of the helicopter can be controlled Around 10 m/s;
Secondly, the landing gear and fuselage of the helicopter adopt an energy-absorbing structure design, allowing the fuselage to absorb impact energy through structural deformation at the moment of grounding. This concept is essentially the same as the collision energy-absorbing concept widely used in automobile design above is the same;

The last point is the impact-resistant seat.This specially designed seat has built-in energy absorbers, which can absorb part of the remaining energy during a fall by the impact-resistant seat.

After such a three-pronged approach, the impact force when the helicopter falls is basically within the range that the human body can bear. Taking the most classic Mi Army "Black Hawk" helicopter as an example, according to the data released by Sikorsky, this A general-purpose helicopter can withstand a vertical crash speed of 11.5 m/s and ensure a survival rate of no less than 85%, while a special-purpose armed helicopter "Apache" can withstand a vertical crash speed of 12.8 m/s with a survival rate of no less than 95%. %—Of course, based on what we know about Laomei, we all know that this must be based on "ideal conditions".

But even so, these two data are amazing, and as the "one tube" of the "three-pronged approach", the role of impact-resistant seats in it is not only used in helicopters, but also by We are extensive in other fields, such as this mine-resistant vehicle.So as soon as these words came out, everyone immediately got heated discussions...

"Yes, yes, the impact-resistant seat must be installed."

"Impact-resistant seats are definitely a good thing, but the price of this thing is not cheap."

"It's not cheap, you have to buy it. Only rely on the body and structure to resolve the shock wave generated during the explosion? I think it's a bit mysterious. It's better to add impact-resistant seats."

"Hey, is there anything else to discuss here? Although the impact-resistant seats are a bit more expensive, don't forget how much our car costs..."

Yup!

As soon as these words were spoken, everyone suddenly realized: impact-resistant seats are not cheap, but the performance of the impact-resistant seats we need must not meet the requirements of impact-resistant seats on military helicopters, plus our anti-mine vehicles It will cost 50 million U.S. dollars, so the cost of the whole vehicle is 150 million. With this manufacturing cost, how many impact-resistant seats can be purchased?

Those who had strongly opposed it just now did not object now, and immediately said: "If you say so, this impact-resistant seat can indeed be used."

"However, what level of energy absorber is needed, this has to be calculated."

"It's all small things..."

…………

Taking advantage of everyone's heated discussion, Zhang Qihang whispered to Cai Xiangdong: "Cai Dong, everyone's enthusiasm is very high."

"Ha ha……"

Hearing what Zhang Qihang said, Cai Xiangdong laughed, and handed Zhang Qihang a cigarette while speaking: "It's rare for everyone to encounter such a good opportunity, of course I'm very happy... You don't know Mr. Zhang, we used to The life of the comrades in the group's military industry department is hard."

"Oh?"

After lighting Cai Xiangdong, Zhang Qihang asked curiously, "Cai Dong, what did you say?"

Knowing that Zhang Qihang and Huateng Industrial Group have been engaged in civilian vehicles, they are not familiar with military vehicles, so Cai Xiangdong is not dissatisfied with Zhang Qihang's seemingly naive question, but after taking a puff of cigarette , and then said: "Mr. Zhang, how do you say this? Don't forget that our Huaxia, not only our Sinotruk Group, can produce military trucks."

"So that's what happened," Zhang Qihang patted his head: "I understand!"

Also!

In our country's automobile industry, FAW and Second Automobile are recognized as the "eldest son" and "second son". Although Sinotruk Group was also a central enterprise before, its ranking must be a little lower than that of FAW and Second Automobile. As a result, the problem also arises: the number of orders for military trucks is limited every year. Although everyone has to take care of it, who should be given more and who should be given less?Under such circumstances, Sinotruk Group naturally has no way to compete with the eldest brother and the second brother, and naturally the number of orders received is the least.

Speaking of this, Zhang Qihang's heart suddenly moved, and he asked Cai Xiangdong: "Cai Dong, there is a question that I have always been curious about."

Cai Xiangdong nodded: "What's the problem, let me tell you."

"Sanjiang Wanshan and Taishan in our province are the only two heavy-duty special vehicle manufacturers in our country, right?" Zhang Qihang said: "Then can our heavy truck group produce this kind of special vehicle?"

What are Sanjiang Wanshan and Taishan Special Vehicles doing? It’s hard to talk about it here, but the vehicles produced by these two units are well-deserved national weapons. The 12*12 log transportation that appeared in the military parade a few years later The car is produced by these two units, and these two units are also aerospace systems, so the status of these two units in the country can be seen.

When Zhang Qihang mentioned these two units, he naturally had some thoughts in his heart.

When Cai Xiangdong heard the words, his expression changed suddenly: "Mr. Zhang, you are..."

Zhang Qihang didn't hide it, nodded generously and said: "Cai Dong, let me tell you the truth, I really don't understand the twists and turns, so I want to ask you, what do you think we Can the group also develop this kind of car?"

That's what happened...

Cai Xiangdong's expression suddenly eased a lot. After pondering for a moment, he said slowly: "It can be done, and the country has not said that other than these two manufacturers can't make this thing, but the problem is, Mr. Zhang, you have to understand that these two companies belong to the aerospace system, and the special vehicles produced by these two companies are also transported by the aerospace system. In the final analysis, they belong to the same system.

So, let's not talk about the technical content of this heavy-duty special vehicle, even if we successfully produced this vehicle, even if the performance is better than the products of these two units, but Do you think the aerospace system can let us come in and get a piece of the pie?Those two units are the sons of other aerospace systems. "

"Tsk..."

Hearing the words, Zhang Qihang couldn't help picking up his teeth, thinking that his thinking was simple: this is really the problem.

On the other hand, Cai Xiangdong, seeing Zhang Qihang frowning, hesitated for a moment, lowered his voice and asked Zhang Qihang: "Qihang, where is the technology of this special vehicle, um... Sanmao is also very good, but also Just Da Mao and San Mao, so..."

Speaking of this, Cai Xiangdong lowered his voice again: "Can you get this technology?"

But Zhang Qihang shook his head: "What's the point of getting what you can't get, let alone whether you can get it, even if you get it, isn't this thing still a dragon-slaying skill for us?"

What is Dragon Slaying Technique?

It is very powerful, but it is useless to use the ability of the place, which is called dragon slaying skill.

If Zhang Qihang can really get this kind of special vehicle technology from Da Mao and San Mao, it will definitely be a good thing for Taishan Special Vehicle and Sanjiang Special Vehicle, and their bosses will be happy for three days and three nights Well, maybe the bosses of these two units can be promoted to a higher level by virtue of this contribution, but for Sinotruk Group, this is a complete dragon-slaying skill.

But Cai Xiangdong's eyes widened, and he said in surprise: "Can you really get it?"

Looking at Cai Xiangdong's appearance, Zhang Qihang couldn't laugh or cry: "Cai Dong, just now you advised me not to think about it, saying that other people's aerospace systems can't take care of our business, why are you so interested?"

Cai Xiangdong shook his head and said: "You can't say that. If we are asked to develop a heavy-duty special chassis from scratch, then I don't say anything. I definitely can't persuade you to do this thing. It's too expensive. It can be said that it is a Bottomless pit!

But if you can get the technology of this heavy-duty special chassis, we can do it. I think this kind of heavy-duty special chassis still has a certain market in the civilian field. For example, it can be used as a chassis for heavy-duty wheeled cranes. With this thing, crane manufacturers such as Sany and XCMG can replace the chassis of some heavy cranes from the current crawler type with this special heavy-duty wheel type chassis.

For another example, in the oil and gas field, there is a special need for this kind of heavy-duty wheeled chassis with strong off-road performance and load-carrying performance. We can also develop the market in the oil and gas field. "

Speaking of this, Cai Xiangdong looked at Zhang Qihang with piercing eyes: "These cars may not sell much in a year, but as long as this market can be established, the annual profit is not a small amount. The key is the quality of this thing. The technical threshold is very high, and it also has a strong exclusivity, so, Mr. Zhang, how sure do you think it is?"

Before Zhang Qihang, he really didn't think about the field of civilian special purpose, but now he heard what Cai Xiangdong said, and he also felt that it made sense: this kind of heavy-duty and high-mobility off-road load-bearing chassis, in addition to military applications, should be used in the civilian market. Is it also useful?

However, Zhang Qihang still didn't dare to talk nonsense about Cai Xiangdong's question. He replied cautiously: "If it was a few years ago...well, five or six years ago, the old Maozi was still relatively chaotic at that time. There are still opportunities, and they are not accepted, but in the past few years, since that Mr. Vladimir came to power, you know a series of moves, so..."

Cai Xiangdong is naturally no stranger to Mr. Vladimir who is called the "tough guy"... Although he is not unfamiliar with the kind of "I know him, he doesn't know me"... After this "tough guy" came to power Cai Xiangdong has also heard about the series of measures, and knows that this young man attaches great importance to Lao Maozi's family background. From this perspective, Zhang Qihang now wants to take this heavy off-road vehicle from Lao Maozi's It is indeed not so difficult to get the technology of the chassis!
Thinking of this, Cai Xiangdong couldn't help feeling a little regretful: "That's it... After thinking about it this way, it seems really troublesome..." Speaking of this, Cai Xiangdong couldn't help complaining: "Mr. Zhang, I heard that you never Lao Maozi bought a lot of good things from there, so many people's eyes are red with envy, why didn't they think of getting some of this technology?"

"Because at the time I thought this thing was useless to Huateng Industrial Group," Zhang Qihang spread his hands and said, "Huateng Industrial Group is a pure civilian automobile manufacturer, how many cars does this thing sell a year? Instead of doing this thing, I might as well make a few more cars."

"..."

Cai Xiangdong was speechless for a moment.
