Compared with Qi Baoshan's excitement, Lin Baoguo was much calmer first, if the solution to the problem was really so simple, would his son not sue him last night? There must be something he didn't expect, and he said in a deep voice, "Stinky boy, this thing is not so simple, right?" ”

Qi Baoshan was slightly stunned, and then he reacted: Yes, if the solution to the problem is so simple, why didn't Lin Zheng tell his father last night, but he didn't say it until he came today? It doesn't make sense.

If it doesn't make sense, there must be a reason.

"Of course it's not that simple," Lin Zheng nodded with a wry smile, "If the district agricultural machinery tractor factory can produce this kind of semi-trailer, of course it is very profitable, but I don't know if our domestic automobile companies already have semi-trailer heads in production, and whether those dealers who import the heads will force the units that buy the heads from them to buy trailers from them...... Don't talk about this, just talk about the most important part of the trailer: the axle, there seems to be no manufacturer in China that can do it, right? ”

There are not many semi-trailer heavy trucks in China at this stage, and the front of the car is basically all imported, anyway, Lin Zheng has not seen a domestic semi-trailer on the road, but the truck that has lengthened the compartment has seen a lot, and these imported semi-trailer heavy trucks are mainly used for container transportation in ports and terminals, and the price is expensive.

"Axles?" Qi Baoshan hesitated for a moment and asked, "Is it difficult to make axles?" ”

He was a little skeptical of Lin Zheng's words, those full-trailer trucks running on the road, one car also pulls twenty or thirty tons, since this axle can be used, why can't it be used on trailers?

Lin Zheng understood why Qi Baoshan had such a look, and explained to him, "A semi-trailer heavy truck usually needs to transport more than 3o tons, but with our national conditions, a semi-trailer that can transport 2o tons will definitely carry forty or fifty tons or more, two axles at the front of the car, two axles at the trailer, a total of four axles, and bear the weight of forty or fifty tons......"

Without Lin Zheng finishing speaking, Qi Baoshan himself let out a "...... ah".

He immediately realized that he had thought about the problem simply, and now the largest load integral heavy truck sold on the market is only four axles, with a load capacity of only twenty or thirty tons, which is already the best axle that can be produced in China, but those semi-trailer heavy trucks, which are also four axles, have to bear double the weight, and the safety is immediately drastically reduced.

The strange Lin Zheng said that the axle is the main problem, and if the rigidity and strength of the axle are not solved, what is the use of welding a carriage frame?

"To solve the problem of axles, the price of foreign technology introduction needs to be hundreds of millions, even if it is based on the domestic metal research institutes to solve, the funds needed are tens of millions or even tens of millions, such a large amount of money is definitely not what we can afford in Yueshui District and even Langya City, only to solve the problem of axles, we can talk about the problem of semi-trailer cars...... By the way, the support axle without the drive function and steering function used in the semi-trailer car is the lowest technical content of all axles, and the steering axle and the drive axle are more technically difficult. ”

Millions? The light in Qi Baoshan's eyes gradually weakened: Lin Zheng is right, tens of millions, such a large sum of money is not something that Yueshui District and even Langya City can afford.

Although Lin Zheng didn't say some things, he could also imagine that even if tens of millions of dollars were invested, they might not be able to get results immediately, but the money went in but couldn't get results immediately, what should I do about it?

"Is it a dead end? Can't solve it? Lin Baoguo also frowned, he now finally understands why his son didn't say it last night, there is a way, but there are many difficulties, it is almost impossible to achieve, an idea that says it and doesn't say it, it's better not to say it.

"This ...... I can only think of a way from the Sinotruk Group," Lin Zheng hesitated, turned his head to Qi Baoshan and asked, "Uncle Qi, is the Sinotruk Steyr project that the Sinotruk Group is cooperating with the Austrian Steyr Company have now been completed?" ”

Qi Baoshan was the small leader of the secretary of the Haidai Provincial General Office before he came down, and he should know some information about this matter.

"Are you talking about the "Heavy Duty Vehicle Manufacturing Technology Transfer Contract" signed by our country and the Austrian Steyr company at the end of 1983?" Qi Baoshan shook his head with a wry smile, "It's in the acceptance stage now, and the entire project has been accepted, almost from April to July next year." ”

"Haven't finished it for so long?" Lin Zheng's eyes widened, he thought that the entire project had already been completed, and now Qi Baoshan told him that the project was only in the final acceptance stage?

"You think this project is that simple? From the beginning of the project to the present, we have received 44 batches of 441 boxes of product drawings and technical data from Steyr, these product drawings and technical data add up to 22435 kilograms of weight, which is almost 22.5 tons of paper, these materials not only contain the motor, subbox, drive axle technology, but also the second introduction of fuller transformer, ZF substation, ZF steering machine and ABCO pneumatic components and other product information, you don't want to think about how long it will take to read these materials, Not to mention that it still needs to be digested and absorbed, this time is fast enough. ”

"Introduced transaxle technology?" Lin Zheng's eyes widened.

"Of course, transaxle technology is one of the main core projects of the Steyr project, how can it not be introduced?" Qi Baoshan looked at him strangely, and suddenly blinked, "What?" ”

"If we master the drive axle technology, it will be easy to do, and the drive axle project, the support axle technology used on the trailer is much simpler, and the support axle can be simplified on the basis of the drive axle technology." Lin Zheng's voice trembled, originally he thought that there was basically no hope for this matter, so he didn't take it seriously, but now listening to Qi Baoshan say this, Lin Zheng suddenly realized that his idea was really possible?

That's a big deal.

"Simplifying the support axle on the basis of the technology of the drive axle?" Qi Baoshan's eyes lit up scary, "Is this okay?" ”

"Why not? The big bag in the middle of the drive axle is stuffed with all kinds of gears such as main reducer, differential device, wheel transmission, etc., you think, these gears not only have to bear the huge force transmitted by the gearbox, but also have to drag such a heavy body, what kind of bad working conditions are dù? How strong is the entire drive axle required? ”

"But the support bridge is different, have you seen the wheels and axles of the ground row car? You can think of it as a large ground axle with pneumatic brakes, and most importantly, a very rigid one-piece axle. ”
