Liu Bei had a car. It was a very exquisite car. It had large wheels with colorful gold patterns. It had no cabin but only seats. The wheels were very big and the seat looked very small. It could only accommodate one or two people.

The special thing about the shape of the car is that it is a car with its own parasol, or to be more precise, it has its own canopy. That is [under the canopy, the man with golden robes and golden armor, Yan Liangye], that is, Yan Liang died under it

That canopy.

Li Mengxi saw that the car exuded a very luxurious atmosphere from top to bottom, and he curiously walked over to take a look.

After walking around the car, Li Mengxi discovered that the car was painted inside and out. It was like an oversized giant lacquerware.

Even the wheels of the car are carefully painted with complicated patterns, and you can tell at a glance that the workmanship is expensive.

Liu Bei saw that Li Mengxi was very interested in the car, so he asked Li Mengxi to get on the car and try it out.

Li Mengxi climbed into the car and sat on the hard seat. As soon as he sat on it, he felt that the car was not comfortable. The seat was hard and narrow, with no obstructions on the left and right, and the backrest was not straight.

Slim, which means that he can only sit upright and upright.

Let Li Mengxi take a look at it. This car is just a show-off, a luxury car, and not comfortable at all.

What he didn't know was that in ancient times, etiquette was valued above all else. The car driving was deliberately made like this, with the seats deliberately made upright, narrow and upright. Sitting in such a car, it is impossible to think about being upright or not.

After a while, Xiao Bian ran over.

Xiao Bian saw such a beautiful car and saw Li Mengxi sitting in the car. Xiao Bian also wanted to get in.

Liu Bei was very kind to the Li Mengxi brothers. The emperor gave him a chariot. Before Guan and Zhang got on, he asked Li Mengxi to get in and play around.

Liu Bei pushed Xiao Bian into the car. When Xiao Bian got in the car, he also sat on the seat. The seat was really anti-human. Xiao Bian could not sit for a while without feeling uncomfortable.

For a kid, if it's not fun, it means nothing.

Xiao Bian felt uncomfortable, so he stood up and jumped on the car vigorously, making the car sway and making himself giggle.

On the side, Guan Zhang and others looked on with smiles.

Li Mengxi was afraid that Xiao Bian would jump him down again and he would have to hold Xiao Brick's clothes.

The little brick bounced like this for a long time. Li Mengxi suddenly noticed something unusual in the regular ups and downs of the car. Why was the car he was sitting on bouncing? How could it be like this?

It's bombing.

Out of curiosity, Li Mengxidong jumped out of the car with a loud sound.

Mr. Li was still a half-grown child. He was small and the car was high, so he climbed under the car effortlessly.

There was a sound of winter behind him, and Xiao Bian jumped down and climbed under the car.

Li Mengxi came under the car, and the chassis of the car was above his head. He raised his head and looked up, and for some reason, under the chassis, there was a large bent iron plate. The iron plate was very big, and it seemed like this thing.

The car was set up.

Li Mengxi's first reaction was that this car was awesome. The chassis of this car was made of steel.

But why does the car bounce so much? It looks like it has yellow bullets.

I looked left and right, the wheels were pulling and the axles were pulling, but there was no yellow spring.

Li Mengxi got under the car and couldn't get out. Liu Guanzhang didn't understand why and put his head under the car to take a look.

"Xi'er, what are you doing here?" Liu Bei put his head in and asked.

"Oh, let me take a look." Li Mengxi replied.

"Xiao Bian, you get in the car and jump a few more times." Li Mengxi instructed his younger brother.

My younger brother is very obedient and jumps as he is told.

After waiting for a while, Xiao Bian climbed back onto the seat. He jumped up and down hard, shaking the car, and then asked loudly, "Brother, are you still jumping?"

"Continue!" Under the car, Li Mengxi looked up at the slightly vibrating chassis without blinking.

The little brick then continued to bounce on the car, and as the car shook and vibrated, I could see under the car that with every vibration, the arched iron plate under the car would deform slightly, and then make a squeaking sound.

Li Mengxi understood somewhat clearly that it seemed to be the elasticity produced by this bow-shaped iron plate.

However, the iron plate is also springy?

This involves Li Mengxi’s misunderstanding of knowledge.

Climbing out from under the car, Li Mengxi patted the dirt on his knees. He pointed at the car and asked Liu Bei, "Mr. Xuande, can I dismantle this car and take a look?"

"Tear it down... tear it down... what will you do if you tear it apart?" Liu Bei looked calm, but he stuttered when he spoke.

"I want to see how this car is made." Li Mengxi replied.

Liu Bei looked hesitant and opened his mouth a few times, "Okay, let's tear it down!" Liu Bei gritted his teeth and agreed.

Guan Yu, Zhang Fei, and Jian Yong immediately looked at Liu Bei.

A chariot is not an ordinary thing, but an important tool of etiquette. This is a chariot given by the emperor himself, so it is no longer important.

Li Mengxi wanted to tear down such an important thing, but Liu Bei just let it go. He could not be more doting on it, even his own son was not so doting on it.

Li Mengxi is not good at dismantling cars, so he has to find professionals.

Li Mengxi led someone to pull the car to the carpenter camp. The carpenters saw a very gorgeous car entering the camp from a distance. The carpenters all put down their work and came forward.

"Ah, military advisor, this car is beautiful." The carpenters gathered around and touched the car here and there with fondness.

Li Mengxi ordered, "Find a few people to take apart the car and take a look."

The carpenters suspected that they had heard wrongly and were stunned for a moment.

"Dismantled...dismantled?" The team leader pointed at the car in surprise.

"Well, take it apart and take a look." Li Mengxi said casually.

A good car was dismantled immediately. Although the carpenters were puzzled, they could only act according to the order.

The craftsmanship of Liu Bei's luxury car must be very advanced, and the structure must be complicated. It can be seen from the way the carpenters carefully scratched their heads around the car.

The most powerful carpenters in the camp climbed up and down the car and looked around before starting to take action.

With the disassembly, the first thing to be removed was the handlebar, then the support of the seat, then the seat, and then, the arched iron plate that made Li Mengxi curious was lifted off.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Li Mengxi walked over, pointed at the iron plate and asked the craftsmen, "What is this iron plate made of?"

Most carpenters have never seen such a high-end car, so they don't know what an iron plate is.

An older carpenter said that he had helped make this kind of car. According to the old carpenter, a bow-shaped iron plate was supported under the car to prevent it from swaying when driving.

The carpenter's expression was not clear enough, but Li Mengxi understood clearly that the arched iron plate actually worked like a spring to absorb shock.

[A book-chasing app recommended to me by an old book friend I have known for ten years, the Changyuan app! It is so easy to use. I rely on it to pass the time while driving and before going to bed by reading and listening to books. You can download it here. huanyuanapp ]

Li Mengxi crossed his arms and stared at the big iron plate, (Interesting.) He thought to himself.

After a lesson, the arched steel plate turned out to be yellow.

If you think about it more carefully, aren't bows and arrows also arched elastic structures?

Therefore, if the spiral spring cannot be made, it is not possible to use a wooden bow instead.

Once upon a time, when Li Mengxi's bones ached due to the bumps of the carriage, he wanted to get out the springs and install them on the car one day. He thought that the springs were extremely difficult to make, and thus misjudged the difficulty of making a shock-absorbing system. Unexpectedly,

, it turns out that the simple shock absorption system only needs to make an arch plate.

Li Mengxi and the carpenters discussed the technology of installing shock absorbers on vehicles. Considering that steel plates were a bit expensive but wood boards were cheap, he asked the carpenter which kind of wood had the strongest elasticity. The carpenter replied that any wood made from rolled wood or wax wood could be used.

While replying, the craftsmen also pointed out the shortcomings of the wood. The boards could not withstand long-term bumps. The boards could be used for a while, but when they were installed, they would break after being bumped for less than two miles.

Wooden boards are not durable enough, and iron boards are too expensive, which makes the vehicle shock absorption system extremely cost-effective. It is no wonder that all the cars we have seen for a long time are bare-board vehicles.

By dismantling Liu Bei's car, in addition to gaining technology, the axle is also gained. In Liu Bei's car, the axle is made of metal, and the hubs and spokes are all exquisite metal parts. Plus some other miscellaneous gadgets, there are many interesting things.

.

It is suspected that Liu Bei's luxury car has obtained the most advanced car-making technology in the entire Han Dynasty. There is a great need to research and imitate this luxury car.

Li Mengxi asked the craftsmen to draw all the parts of the car. At this time, the previous layout came in handy.

Very early on, when he was still fighting the Yellow Turbans and on the way to the war, when he was discussing craftsmanship techniques with the craftsmen, Li Mengxi realized a problem at that time. He found that when communicating with the craftsmen, he could still talk about simple things.

Qing, if it is a little more complicated, you have to draw a rough pattern on the ground with a stick. If it is more complicated, sketching is not enough for communication.

Anticipating that the things that need to be manufactured will become more and more complex in the future, communication and communication issues will become more and more important. Therefore, Li Mengxi thought of unifying the workpiece drawings and the method of unifying the workpiece drawings, which is the three-view method.

The three-dimensional view has been implemented in the military for some time. Although the implementation effect is not good, the effect is still there. Now it is necessary to make the three-dimensional view. There is no need to watch every step. The craftsmen can draw it by themselves.

come out.

Since there is only one luxury car, it must be properly preserved. This is the first equipment in the military that needs to be copied. Therefore, it has become necessary to establish a special storage mechanism.

The craftsman camp now has its own material warehouse and finished product warehouse. Li Mengxi ordered a new drawing warehouse to be built. All the detailed workpiece dimensions of the creation, all the skills accumulated in daily life, and all the knowledge of manufacturing details are all stored in the drawing warehouse for safekeeping. The luxury cars that are the subject of production and research are also stored in the drawing warehouse.

In the future, if there are other exquisite creations that are not found in the army, they will also be stored in the blueprint warehouse.

Drawings are delicate, and samples are also delicate. This requires the drawing warehouse to be moisture-proof, moisture-proof, fire-proof, mouse-proof, and other prohibition standards must be high.

To build a high-end warehouse, this is the work of the construction team. Construction craftsmen and professionals are called in and a feasible construction plan is given on the spot.

In order to prevent moisture and humidity, the builders suggested using several layers of soil to make the foundation higher than the ground, and then spreading lime inside the warehouse to prevent moisture. Since the warehouse in the drawing does not need to be too large, the roof does not need to be too large either. The entire roof of the warehouse can be used The left and right beams are horizontally framed, and the rafters are carefully arranged. Good firewood is used, mud is poured out, and tiles are used as pads, so that as long as maintenance is frequent, there will be no leakage.

Considering moisture-proofing, it is best to make the eaves larger and leave some light holes high in the walls. This way, light can enter and rainwater can be prevented from entering obliquely.

If there is light in the warehouse, it will not be too wet.

Also, it is best to make the wall shorter, because if the wall is too high, it will be difficult for the light to reach the innermost part.

It is best if the light can shine directly from the wall hole to the center of the warehouse.

In view of the need for pest control in the drawing warehouse, the builder suggested that more airy wood be used in the warehouse. This airy wood refers to wood that has its own smell, such as camphor, chun wood, etc., and camphor wood can The wood from which camphor is extracted is the Ailanthus altissima tree. It is said that where the Ailanthus altissima is located, there are not even mosquitoes.

To prevent fire, more partition walls can be built inside the drawing warehouse. To prevent rats, it is best not to use rammed earth in the warehouse, but to use a dense layer of stones.

The construction craftsman directly explained the complete construction plan, and Li Mengxi just listened.

Finally, the craftsman asked how big the warehouse should be. Li Mengxi thought carefully about it. All the creation samples should be placed in the blueprint warehouse. The creation samples may include ships, towers, trebuchets, curved shaft plows, crossbows, knife carts, and vehicles. , water wheel, columbine, and other utensils, so it is best to build more warehouses.

In order to build the drawing warehouse, which is also a technical center and involves core secrets, corresponding guards, management and other manpower must be prepared at the same time, and a new organization was born.

The new organization, according to its division, should be classified as the [Drawings Department] under the Ministry of Industry. The Drawings Department is directly under the highest jurisdiction of Mr. Li.
