'Buzz ......'

The sound of the huge engine resounded through the main test site, and with the increase in the sound of the engine, the black smoke became thicker and thicker, but along with it, the strange-looking truck was getting faster and faster. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The front view of the truck is not much different from that of a normal truck, but when you look at it from the side, the difference is huge.

First of all, the truck does not have the body of a normal truck, and in the back, there is a flatbed about ten meters long, the same height as the bottom of the truck's body, and at the back of the flatbed, there are two mobile bridges.

At this time, on the trailer of this truck, a wild boar tank was quietly parked there, allowing the truck to pull him around.

Compared with the tank, the maintenance of the truck is relatively simple, and the truck is also more durable, unlike the tank, the slightest problem will strike, so, don't look at the production cost of the tank is only more than a thousand taels of silver, but in fact, if you use it, this cost is not something that ordinary people can enjoy.

Now the empire has formed two divisions of armored troops, and these two divisions are not all equipped with boar tanks, mainly because the output of the factory can not keep up, originally they wanted to expand production capacity, but because of the opening of the new capital, and Beiping is not suitable for large-scale construction of tanks, and at the same time, in order to facilitate the emperor to visit the factory at any time.

Therefore, the factory plans to build a new large-scale factory in Luoyang, which will produce tanks when there is a task and tractors when there is no task, so as to ensure that the factory can barely survive.

The factory in Luoyang was already being built as early as when Wang Sirui announced the use of Zhongjing as the new capital, so the factory should be put into use earlier than the new capital.

At this time, the test site is at the junction of the mountains and plains in the southwest of Luoyang, which can basically meet the needs of the experiment, as long as the prototype can pass the experiment here, then at least more than half of the areas in the country can be guaranteed to be fine.

Wang Sirui came to watch the test with not only the imperial premier Wang Shizhen, but also the commander-in-chief of the artillery Duan Qirui, who was reporting to work in the new capital, and Cao Kun, the commander-in-chief of the Korean Army Corps who returned to Beijing to report on his work.

At the beginning, everyone felt that this design seemed to be a bit chicken, the tank itself could move, there was no need to spend energy on researching a trailer designed for tanks, and even most people thought that designing this trailer was better than producing more trucks, and it could pull people and materials, how cost-effective?

"Your Majesty, this type 1 trailer has been modified several times, basically has met your requirements, and this prototype has been continuously tested for a month, the mileage has reached more than 15,000 kilometers, a total of five maintenance, but some minor maintenance, as long as the oil and filter elements are changed, check the brake system.

Because of the use of a new diesel engine with 300 horsepower, so in the case of an empty car, the maximum speed can reach 90 kilometers per hour, equipped with a tank, the maximum speed can reach 60 kilometers per hour, but this is the limit speed, continuous use, will have a certain impact on the front of the car, plus the road conditions, so in the test, we are to maintain a speed of 30 kilometers per hour test. Shang Zhu, who has been promoted to the chief engineer of the Imperial Automobile Factory, once again stood beside Wang Sirui and carefully introduced the situation of the trailer for him.

As the first batch of industrial talents vigorously cultivated by the empire, Shang Zhu and others, who already have a good foundation, with the help of the Ford team, did not live up to Wang Sirui's expectations for them.

This tank trailer is actually not complicated, because the tank itself weighs only eleven tons, and even if it carries the crew and the corresponding combat materiel, it will never exceed twenty tons.

Moreover, this is not a commercial vehicle, there is no need to think about comfort, they want quality, performance.

Shang Zhu, who has a lot of design experience, quickly designed a new trailer according to Wang Sirui's requirements, and entered the construction experiment stage, but at the beginning he still encountered big problems, for example, because the design of the car body is not very reasonable, and the car body cannot withstand huge pressure due to long-term load operation, resulting in breakage.

In order to solve this problem, Shang Zhu took the simplest way, strengthen the chassis, increase the wheels, so that the load-bearing force is more dispersed, and then the brake system, which was originally designed to only have the front of the brake system, but because the trailer is too heavy, the trailer continues to push the front of the car forward when braking.

This is also in the testing ground, and if you go outside, it will kill you.

Therefore, a separate braking system for trailers has been proposed, but at present, no factory in the world has experience in the manufacture of split brakes.

The trailer and the front of the car can be separated, so the braking system can only be two sets. In a coincidence, Shang Zhu suddenly came to inspiration, so he made a one-to-three brake line on the front of the car, that is, the cab was divided into a main brake line, which was divided into three in the middle of the body, and the two wheels on both sides were controlled on the left and right, and the middle one was reserved, and a set of such devices was also made on the trailer, but the front line was not connected to the cab, but to the brake line that was reserved.

In this way, once the two brake lines are connected, the driver only needs to apply the brakes to control the front of the vehicle and the trailer at the same time.

It's a dumb approach, but for now, it's clearly working well.

Wang Sirui doesn't seem to have any reason to be dissatisfied with this trailer, but the only thing that makes Wang Sirui frown is that the frequency of maintenance is too high, right?

It was maintained five times at 15,000 kilometers, with an average of once every 3,000 kilometers, although this distance is not unacceptable, but it always feels a little fucked.

"How's the off-road ability?" Wang Sirui did not dwell on the problem of maintenance, although the maintenance of 3,000 kilometers is a bit frequent, but compared to the delicate tank is still very worthwhile.

"In the case of full load, the maximum climbing degree of the bicycle is five degrees, but there are strict requirements for the driver, from the beginning of the climb, to the end of the climb, there can be no problems in the middle, if it is parked in the middle, it is difficult to start again. Considering the practical purpose of this car, we also gave a solution.

If you encounter a steep terrain, you can combine two cars together and use the pull of the two vehicles to pull a trailer to climb the hill, although the speed will be slightly slower, but with our current technology, this is the only way to do it.

But then again, we designed this vehicle to be used primarily to carry tanks, and the tank itself has strong off-road capabilities, in other words, even if we encounter a slope that the vehicle can't climb, we can let the tank start and climb up on our own, or use the tank to pull the empty car up in front.

Therefore, if it is only used to carry tanks, then the cross-country ability of this vehicle can hardly be considered, as long as there is a tank, even if it is stuck in the quagmire, it can be easily pulled out, and we have done several experiments in this regard. Shang Zhu explained.

This Nima ......

Why did Wang Sirui suddenly feel that he had been deceived? You were asked to design this car mainly to carry tanks, but Nima is good, even the tank is calculated, although it sounds very reasonable.

But the question is, the front of the car is not just for carrying tanks, otherwise why not design the car as a single piece? Wouldn't that be more convenient?

The advantage of the detachable type is that if you replace the trailer with a bucket truck, isn't that a ready-made transporter? Not to mention the military aspect, even the civilian aspect is also very cost-effective.

"This design is okay for tank trailers, but it must increase the horsepower of the front of the vehicle, and it will have to carry other goods in the later stage, which has no ability to move, and you know what the next generation of tanks will look like, can you still pull this trailer when the time comes? You know better than anyone else. After passing the test, 500 sets will be produced first, and we must not slack off on research and development, and we must develop a front and trailer with greater horsepower and bearing capacity as soon as possible. Wang Sirui thought about it for a while, and finally recognized the design.

The maximum climbing ability of five degrees is not too bad, the maximum slope of the highway in later generations is three degrees, and the heavy-duty trucks of these later generations also need a special climbing lane to climb slowly, and the slope of the basement is only eight degrees, so the performance of this car is still very good.

But given the current state of the road, this is not enough.

"Your Majesty, the tank itself has the ability to move, and if you carry this again, I'm afraid it's a bit of a waste of resources, right?" Duan Qirui questioned that Duan Qirui has been making reports recently, requesting that the artillery unit be equipped with enough trucks to carry artillery.

Last year's Korean War made the artillery lose face, and if they had trucks at that time, it is estimated that the infantry would not have been able to catch up with them.

Later, it was equipped with fifty trucks for artillery, and Duan Qirui also set up an artillery mobile regiment, but the result was good and scary.

However, the infantry was not easy to greet, seeing that the artillery had trucks, but the infantry could only rely on two legs, so they also reported and asked for trucks.

But there is only so much production capacity, and the infantry and artillery are even more vying for it, both openly and secretly, and the two sides don't know how many times they have already fought each other.

But no one thought that the armored soldiers, who did not lack mobility ability, would also come in sideways, and they were also hand-picked by the emperor, which made people a little embarrassed.

In Wang Sirui's view, the tank trailer is just one of many black technologies......
