"This seems to be a bit similar to Mercedes-Benz heavy trucks." Thinking of this, someone said it.

Although only part of it was imported because of the price problem, and it was constrained on the issue of self-production, it has to be said that the quality of Mercedes-Benz heavy trucks is definitely the best.

"That's right, it uses the same chassis as Mercedes-Benz heavy trucks and products from the same supplier." Qin Zhenhua said.

The well-known European company ZF is famous for producing these parts. At the same time, people's technology is definitely good enough.

To what extent? In later generations, there was a certain independent first SUV company that created an urban SUV codenamed H8, imitating Mercedes-Benz chassis, with quite strong performance, but it was repeatedly bounced and postponed for a year or two and could not be listed.

Why? Because there is a knocking sound on the chassis, the car is longitudinally four-wheel drive, and the propeller shaft transmits power to the rear axle, and as a result, when the speed reaches 150, there is a strange sound from behind.

Although the speed limit on domestic roads is 120, but for a high-end car, it is possible to run to two hundred, which is a pain for the technical staff at the time, no matter how to find it, but can not find the reason, and finally there is no way, find foreign aid.

Please foreign aid, is ZF company, people look at it, the quality of your manufacturing is not good, with ours, people directly put their own production of the back axle to install it, obviously it is exactly the same data, but, installed on the back axle, there is no knocking sound!

Moreover, after running tens of thousands of kilometers, I took it apart and saw that there was not even a single broken iron slag in it!

That's technology!

In later generations, there are many brands of heavy trucks in China, but in the promotion of heavy trucks, the use of imported ZF steering machine is a very brilliant place, as long as there is this, it is very stable!

And now, the country is definitely unable to match the corresponding products, in a short period of time, a machine factory itself can not focus on every part, so some of the imported, just take the doctrine.

However, in the later stage, these parts must be localized, and it is impossible for a domestic infantry fighting vehicle to be purchased from the top.

"What is its engine?" He Lao asked.

For China, a huge shortcoming, is still the engine, ready to participate in the parade of the WZ523 armored car, although the use of diesel engine, but the power is only 165 horsepower, simply not enough, maybe on a straight road can soar out of 80 kilometers per hour speed, but in the field, the off-road speed will drop rapidly, absolutely can not keep up with the advance of the tracked troops.

"It's a diesel engine, we have prepared two." Qin Zhenhua said: "One is Steyr's WD615 engine with 260 horsepower, and the other is Deutz's air-cooled diesel engine with similar power. Both are mated to a nine-speed gearbox. ”

In fact, this wheeled armored vehicle has complex technology and a wide range of sources, and it also has a lot to do with the Hanyang plant, ZF steering machine and Deutz air-cooled diesel engine, Hanyang plant is now in use, so they took it, in fact, it is the relationship of the Hanyang plant, as for the diesel engine of Steyr company, now the cooperation with Steyr has begun, and the initial production is in the way of CDK, so the number of diesel engines introduced is also quite a lot, and it is just taken over for emergency purposes first.

Both have their own merits, for an engine, the use of air cooling, can greatly reduce the complexity of the operator, now there is no advanced coolant, the use of ordinary water, in the cold winter, at night to release the cooling water, in the morning to use hot water, and air-cooled, nothing is needed, just start it.

However, the water-cooled engine can be given a good working temperature, so that the engine always works in the most suitable temperature range, and in many working conditions, there is no need to worry about the high temperature of the engine, and the adaptability is wider.

Which one to choose, or depends on the last troops, in short, these are no longer a problem, a machine factory has almost taken the doctrine to the extreme.

After all, in the eyes of everyone, the most important thing for a car is the engine! The performance of the engine directly determines the quality of this car, and a machine factory, which has always been self-reliant, actually started a large-scale outsourcing when building this armored car?

"In other words, you're just making a shell." Counselor Wang concluded there.

The engine, gearbox, steering machine, these are all purchased, this car looks bluffing, in fact, you have nothing in a machine factory.

What Staff Officer Wang summed up is also the thoughts in the hearts of some people.

Qin Zhenhua smiled: "Of course, it's not just a shell, everyone, a car, what does the off-road performance depend on?" The engine and gearbox are to have a certain relationship, but in addition to these, there are some that are very important! Besides, you can all see that our car is different from the existing ones. ”

"Axle bar." He Lao said.

The three major parts of the car, the engine, the gearbox, the axle, now, the first machine factory is most proud of this axle.

"For a wheeled armored car, the layout and quality of the axle, directly determines its off-road ability, we have made a lot of effort in this regard, we have adjusted the distance of the axle, so that the front, middle and rear three axles, the spacing is equal, at the same time, we use the wheel reducer, so that the ground clearance of the axle becomes very high, compared with Dongfeng off-road trucks, the performance is a big improvement."

Dongfeng's off-road military vehicle, or the most common structure, the front engine through the transmission shaft, gearbox, when transmitted to the rear axle, the speed is still very high, so it needs to be decelerated, the larger the reduction ratio, the larger the gear in the center of the rear axle, the larger the size, which affects the passage of the vehicle, this place is easy to get stuck on the ground.

At this time, a new technology has emerged, the driven gear in the center of the rear axle is smaller, and the speed transmitted to the half shaft is very fast, and then, when passing through the axle head of the wheel, a group of planetary reduction gears are set up in it to carry out a deceleration, so that it is enough.

At the head of the axle, it is the edge of the wheel, so it is also called the wheel reducer, which is a relatively advanced layout.

"Wheel reducer, is it the technology of Steyr heavy trucks?" Someone asked.

Now, the only wheel reducer in China, is just introduced Steyr's heavy truck project, when the domestic test, the army also participated, this technology is in love, ground clearance has improved a lot, and it is also more durable and durable, and the heavy load slope will not break the half shaft.

Qin Zhenhua shook his head: "No, it's the technology of Mercedes-Benz heavy trucks." ”
