Chapter 206

Qin Miao looked at Fan Gui in front of him, his expression also became solemn: "Section Chief Fan, as long as you are willing to do as we require, you will surely find a broad road ahead! Within three months, we will send the design drawings to you; after you go back, prepare for construction!"

Good!

"It's getting late, let's go, I'll treat you to a meal in the cafeteria."

"This…"

"Come on, no need for you to hand over grain coupons!"

Fan Jian kept a black face, said nothing, ate in silence, actually ate enough for two people, as if venting his dissatisfaction.

Qin Miao also ignored him, chatting with Fan Gui.

"We're building missile launch vehicles, just a start; later our products will expand, for example, large automobile cranes will need this chassis, mining trucks will also need this chassis, departments like petroleum, surveying, geology, etc., all have demand; in this field we can achieve a lot!"

"Yes, yes."

Fan Gui nodded frequently, the two got along well in conversation, laughter often came from the table.

Having eaten and drunk their fill, everyone left.

On the return vehicle, Fan Jian could no longer hold back.

"Brother, Ha Gong Da has no good intentions; they clearly want to get something for nothing!"

"Brother, when will you use your brain and think about what technology Ha Gong Da actually has?"

Fan Jian thought for a moment, shook his head: "I don't know."

"Not knowing is right; the engine is imported, the transmission is imported, only the chassis remains, and this axle still needs us to produce it. Think about it: once we get the axle technology, even if this exported missile vehicle is still their business, what about the domestic market?"

Fan Gui's face full of excitement: "We are originally under the aerospace system; shouldn't the aerospace system give us a livelihood? From now on, domestic missile launch vehicles must be produced by us! The imitation prototype vehicle launching our tactical missiles, the vehicles designed by Ha Gong Da transporting larger missiles—will our Wanshan Factory still worry about having no food?"

"What getting something for nothing? It's not Ha Gong Da taking our technology; it's us taking Ha Gong Da's technology!"

"How much can be exported? Afterwards it will definitely be mainly for our own use!"

Fan Jian finally understood: "Brother, you're still the smart one!"

Fan Gui smiled: "When has your brother ever suffered a loss? After we go back, we'll file a report to the superiors!"

"Good!"

On the other side, after seeing off the group from Wanshan Factory, Director Lu and the others returned to the project office, also full of excitement.

"Great, San Shui, with you, now we just need to modify based on the MAZ-543 axle; we'll redo all calculations, in one month the axle can be designed, in three months the whole vehicle can be designed, delivering the first launch vehicle within a year is no problem!"

Director Lu was extremely excited.

"Well, we need to do all the calculations; it's not just a simple scaling, we must consider all operating conditions, leave a larger margin, the most important thing is…"

Qin Miao looked at Director Lu: "Design the wheel-end reducer one size smaller; it requires the high-strength material developed by our materials department to meet the design specs; using ordinary gear steel would cause tooth breakage."

Director Lu blinked, "What's this for?"

Engine power goes through the clutch to the transmission, then via the driveshaft to the axle; advanced setups might have a torque converter, automatic transmission, etc., but the basic power flow is like this.

After the transmission, the driveshaft speed is still high and cannot directly drive the wheels, so a reduction gear is also installed on the axle.

Among them, the most crucial reduction gear is at the axle center: there is a large disk gear called the basin gear; the larger its diameter and the more teeth it has, the better the reduction effect; at the same time, this basin gear combines with the differential to form the basic structure of the tooth package in the rear axle.

For a road vehicle, such a tooth package is sufficient, but for vehicles needing off‑road capability, an overly large tooth package would affect passability.

Thus the wheel‑end reducer appeared.

Using a small gear at the axle center keeps both half‑shaft speeds high; when the half‑shaft delivers power, at the wheel end—that is, the shaft head—we add a set of planetary reduction gears, lowering wheel speed and shrinking the central tooth package's volume; the only drawback is the complex structure.

The imported Steyr heavy‑truck axle already has a wheel‑end reducer; many later heavy trucks, especially those used at construction sites, need this axle; the Russian MAZ‑543 axle also has this structure, differing only in size.

So this axle technology is really nothing special.

Even without the MAZ‑543 axle technology, expanding the Steyr axle works the same.

Now Qin Miao's arrangement obviously has a deeper meaning.

"If nothing unexpected happens, once Wanshan Factory gets our design drawings they'll surely go it alone; then their products will constantly break gears, while ours will run normally, so…"

Qin Miao never trusted Wanshan Factory!

Besides, with people like Fan Jian around, even if they go back they'll still stir up trouble; we can't fathom Fan Gui's exact attitude, so it's better to keep a backup.

In this era there's basically no talk of patent rights, so we must use technical means to avoid being copied; in this regard, our Ha Gong Da is absolutely professional!

As for them, the vehicles they cobble together easily strip gears… hehehe, they'll surely be disliked by superiors!

Director Lu took a deep breath: "Good."

"Suspension system: we must design and fabricate it ourselves; air‑bag suspension won't work, so we need hydropneumatic suspension; the tire central inflation‑deflation system also must be done by us; for the frame, we'll have a capable factory do the work, and it must be pressed on a ten‑thousand‑ton hydraulic press."

Qin Miao continued arranging other items; next, we'll leave it to the big guys to do—he… he's been busy this long, he needs to rest.

Actually, the axle is just a pit; there are many more pits. Wanshan Factory wants to break away and work alone? Hehehe, go dream!

"Right, the cab—I just have one requirement: we must install an air‑conditioning system, and it must have sufficient cooling capacity; even if the engine is 800 horsepower, using 100 horsepower for cooling is no problem!"

Our customer Mr. Sha is especially heat‑averse; we must give them a good working environment—this is even more important than how far the launch vehicle can go or how much fuel it burns!

Ding‑ling‑ling… the phone rang.

"Hello, what? The Steyr truck has arrived?"
