Suddenly, for a moment, Li Yuanji felt that he had gone too far?

Isn't it too cruel for others to push for these things in this day and age?

But soon, Li Yuanji dispelled this idea of being a holy.

Didn't white people rise in this way throughout history? Although there are reasons for that, only development is the last word.

No matter what others do, their own development can never be stopped, so what can these things do now?

Even if it doesn't come out now, the wheel of history has changed, and it is estimated that in a few hundred years, the world will develop to the level of future generations, right?

Since the finale can't be changed, why don't you let Huaxia and the Han nation become the leaders of this world?

Plunder?

I'm sorry, but in fact, Huaxia is the ancestor in this regard, once the Han people initiate a ruthless attack, the Western countries are simply not enough.

Li Yuanji came to the test site a lot, it was the place where the train group tested the new train, and there were many factories next to it.

As you can see, there are a little more than the last time I came by myself.

You can also see the busy crowd, and even some carpenters are nervously busy.

A small wooden model is placed in the workshop, and it is said to be small, but in fact it is much smaller than the locomotive, but in fact its scale is not small at all.

The length of the car alone is nearly five or six meters, and this is only the length of the front of the car.

It looks roughly the same as a locomotive, and it is a long distance in front of it, and it is all about the deployment of boilers and various equipment.

Looking through some gaps, I found that it was still very empty, there was basically nothing, only a few wooden parts were fixed.

"Your Majesty, this is based on the smallest steam engine that can be made so far, but the size problem can continue to be controlled, but this may affect the final power." Pointing to the wooden model in front of him, Jiang Tian began to explain.

Making models out of wood, which is already a common practice in train workshops, is mainly due to convenience and speed.

There are a large number of carpenters to cooperate with them, and the wood is modified or remanufactured according to the requirements, and a not particularly complex part, an experienced carpenter can do it in less than half an hour.

And this part doesn't need to be how strong or durable it is.

It only needs to be able to operate normally for a while, and in the process of operation, improve the problems of the material itself, such as fracture.

After the whole process is down, it will go to the real battle, and at that time, it is basically possible to assemble a complete train at one time, even if there are problems, they are all minor problems.

"How to turn?" Li Yuanji just glanced at the model, and he could determine that there was no way to turn this around.

Don't ask any too esoteric questions, because his power setting is the same as that of a train, which is powered by the front wheels, which requires that the front wheels must be fixed, and how can it be steered?

Just by seeing this, Li Yuanji knew that these people were still not open-minded enough, and their brains were not big enough.

Or, it can be said that it is conservative and does not dare to let go of the imagination.

For scientific researchers, this is a very bad side, but Li Yuanji is also powerless, everything must have a process, now the whole society is adapting, are changing, in order to reach the level of their imagination, not to mention, it will take at least a hundred years.

"This is one of the bottlenecks at the moment, we have tried a lot of ways, but we have never been able to get an answer, and even refer to the way the ship steers, but it does not apply to this." Jiang Tian said helplessly, this is indeed a problem, or rather, this is a structural problem, but he can't find a good solution for a while.

"What about the other bottleneck?" Li Yuanji then asked, the steering problem is actually very simple, although it has been very complicated in later generations, but now it does not need to be so complicated, only a simple device is needed so that the front wheels can be steered.

It doesn't matter if you have to use a lot of effort to operate, everything is created from scratch, first make the simple one, and then they can study more advanced according to this simplicity.

"The other is the problem of wheels, with the same wheels as the train, you can run on the tracks, but you can't run on the ground at all, and it's easy to get stuck in, we tried to widen the wheels to make it have more contact with the ground, but the effect is still not ideal, it's easy to slip on the spot, and with wood on it, it will soon crumble again, and it won't be used for a long time." Jiang Tian said about the second bottleneck.

Listening to these two bottlenecks, Li Yuanji felt a little like laughing, this special meow is also called a bottleneck? So simple that it's easy to cut down?

Moreover, neither of these two questions involves more professional knowledge, even Li Yuanji, a person who has not dismantled those precision devices, can give a rough idea.

"Let's talk about the first bottleneck, the design of the power transmission needs to be changed, according to the current design, the truck is simply not able to steer. Do you know how the propellers are pushed on board? Li Yuanji wanted to say it in more detail, but it was not necessary to think about it carefully.

I've told myself everything, what do you want them to do?

It was too detailed before, so it restricted their free play, but now Li Yuanji feels that what he should do most is to point out the root of the problem and then let them solve it themselves.

"The propellers on the ship?" Jiang Tian was stunned, he had paid attention, but after reading it once, he didn't care much about it, because a large part of it had the same principle as the train, and it was not difficult to understand.

But soon, Jiang Tian, who was stunned there, thought of a solution.

Jiang Tian, who was excited, slapped his head and exclaimed, "That's right! You can look at my head this way......"

"The rudder can be borrowed from the ship's rudder, and a rudder is also installed on the truck, and the gears are used to control the direction of the front wheels, and the transmission structure can also refer to the propeller pushing mode, only need to be divided into two at the tail, so that it can drive the two rear wheels at the same time, such a simple question, why didn't I think of it?" The more Jiang Tian spoke, the more annoyed he became, the answer to the problem was around him, and even he knew it himself.

Now he doesn't need to refer to it at all, and he doesn't need to ask for other people's opinions, he knows what to do himself.

Although there are a little more things and the structure is a little more complicated, the drive wheels are perfectly shifted to the rear, and the front wheels can be used for steering, and they don't have to be driven like a train.

Li Yuanji smiled slightly, and then said: "Let's talk about the second problem, there is no need for so many wheels in the truck, and there is no need to be so small, it can be larger, one wheel is not good, just two, so as to ensure that its passability is better, as for the problem of skidding, you can use rubber to make an outer wheel." ”

"Well, it seems to be feasible." Jiang Tian thought about Li Yuanji's statement in his mind, and said that it was feasible, but he had doubts about rubber in his heart.

Rubber he's seen, now it's more used for doors and windows, using that as a wheel?

Anyway, the emperor said it, if it doesn't work, let's try it out and find out, if it doesn't work, I'll talk about it.

Hey~~~

In this way, the two bottlenecks can be solved!

As soon as he thought of this, Jiang Tian's face was full of excitement, he could finally see the hope of victory, and he finally had the first project to complete independently.

"And a third question!" Li Yuanji obviously didn't care about Jiang Tian's good mood, and directly said the next question.

Ga......

Jiang Tian, who was in the midst of excitement, was confused, didn't there be two bottlenecks? What is the third question?

"Do you think that with the current design, even if it can really succeed, where will it go?" Li Yuanji asked, this is his biggest headache, some aspects can be lacking, but this aspect must not be lacking, otherwise it will come up with a bunch of things that cannot be used, not to mention the waste of energy and time, and a waste of money.

"Huh?" Jiang Tian didn't seem to understand what Li Yuanji meant.

And Li Yuanji, who was depressed in his heart, didn't want to stay here any longer, so he was sad......

"Practicality! No matter what project he is engaged in, his ultimate goal is to put it into use, the scale of this truck, not to mention the weight after the installation of the trailer, is his own weight, how many bridges do you think Datang can bear such a weight? Or are you going to have me build enough bridges over each river to get these trucks through? Dropping this sentence, Li Yuanji left the test site directly.

In general, there are disappointments, but there are also surprises, after their own points, I believe that the truck can be quickly studied, disappointed, these researchers are still far from their imagination.

In fact, Li Yuanji is most depressed that they completely follow the template of the train to build the truck, before manufacturing, can't you think about it, the reason why the train is so big is because of how much weight he pulled?

Do you expect trucks to pull as much stuff as trains?

The truck is for convenience, coupled with the current geographical conditions, there is no need to make it so big, a small steam engine, and some necessary devices, only need it can pull a few tons of weight, even if it is a steam truck, under such low requirements, it can also make a length of less than ten meters.

However, steam trucks are always inferior to internal combustion engines, one is not strong enough, the second is that you need to carry coal everywhere, the third is that weight is a problem, which greatly limits the carrying capacity, and the fourth is that no matter how small the steam engine is, it is always not as small as the internal combustion engine.

Of course, it's okay to think about it, but as for the internal combustion engine, you don't have to think about it for a short time.
