When I arrived, several heads were gathered together, pondering the few drawings.

"Why, is there anything you don't understand?" Li Dan asked.

It turned out that everyone did not understand the role of the propeller shaft in the middle, and how the front wheel and it were connected.

Li Dan asked for pen and paper and explained it with pictures and writing. Later, Chen Gang's youngest son, Chen Sanwen, was simply asked to carve all the parts out of cork according to the drawings and assemble them into a pair of underframes.

Li Dan stretched out his hand to pull the steering machine, and the transverse gear tossed the longitudinal gear on the end of the transmission shaft, and the rear wheel followed the direction and deviated. Everyone immediately said "oh", and they all understood.

"San Lang's mind is really, ingenious!" Chen Gang exclaimed.

He was a forty-year-old man, and the trade of building a carriage had been passed down from his uncle.

Now his three sons are working with him, Chen Dayong is good at mortise and tenon, Chen Shuangji is good at hardware, and the third Chen Sanwen is clever and can do carving is an all-rounder.

When he heard Li Dan say that he learned from Western books, Chen Sanwen had a mind to learn and began to ask questions around Li Dan.

"It usually takes three or five days to build a carriage, but the first time this thing is done, I can't say it will take longer." When Li Dan asked about the time it would take, Chen Gang replied.

"It's all right, if you build one or two, I'll leave in ten days, and if there are five or six, we'll leave in thirteen days."

"Thirteen days?" Han An was taken aback: "San Lang, from here to ten thousand years, it will take three days on the road!" ”

"I know." Li Dan smiled, pointed to the picture and said: "But if everyone takes the car, the morning and the evening will be in the ear!" But he immediately said:

"Don't worry, it's okay to have two cars when you set off. On the way, if there is any shortcoming, send someone back to inform you immediately, you can modify it in time, so that the rest will be better. As he spoke, he glanced at Han An.

Han An understood what he meant, and immediately said with a smile: "I just took out the picture of the Chen family's father and son and saw the benefits, if the son wants to buy shares, they can't ask for it!" ”

"That's great!" Li Dan was very happy in his heart: "Don't worry, there are a lot of good things in Western books, and when I slowly hand them over to the third brother, we will earn a lot of money."

But my brother settles the account, Ming'er I asked Mr. Han to come over with the contract, let's ask a few neighbors to be a witness and make a white deed first (there is no official certification seal for private contracts, and there is no tax payment), and each other is more at ease! ”

The father and son of the Chen family were still a little worried, afraid that this little Yuanba would take the opportunity to occupy his workshop? Seeing him so crisp and fair, he put down half of his heart and said yes in a row.

When Li Dan arrived home that night, he first went to his aunt to tell her about the manor of the White Horse Temple and asked her to decide. Xiao Qian heard that it was a pawn sale industry received by the temple, and it was not easy to chant the Buddha and say that it was not easy for monks.

Li Dan frowned, thinking to himself that five bald donkeys ate the rent of more than 200 acres of land, what is "not easy"?

In the end, I heard my aunt say: "I think, one hundred and thirty taels let the temple transfer the pawn sale contract to us, and then give the temple ten stone rice every year, plus one hundred catties of vegetables, melons and fruits to worship." ”

Li Dan almost laughed out loud, and hurriedly agreed. Thinking about the contract of three hundred taels, one hundred and thirty taels is not bad next!

plus the sixty-five taels for buying the yard, and the two hundred taels are still five taels, and it happens to be a donkey cart. It seems that it is not so easy for the monk to earn his aunt's silver.

When he woke up the next day, Li Dan hurried out. On the way, he met Li Suzheng and Li Yan, who was talking under the wall of the inner door, and Li Dan hurriedly said hello and saluted.

Li Yan wondered: "What has this son been busy with recently?" Running like a footless cat every day! ”

"The third brother hasn't heard?" Li Su looked at him with a smile, and closed the folding fan in his hand: "San Lang in our house was appointed as the leader of the Minfu team, but now he is very busy?" ”

"Minfu? Team rate? Li Yan was stunned for a moment and laughed: "Okay, team rate!" Let him get busy, as long as he doesn't get into trouble! Li Su smiled when he heard this, and looked at Li Dan's back without saying a word.

Li Dan heard the laughter of the third uncle behind him, but he didn't plan to care.

After this business trip, I will bring everyone back safely, and with the credit of catching the thief this time, if you can mix in a team or even a higher position in the team training, no one can bully yourself and your aunt.

He didn't want to ask for much, he didn't want to overthrow the dynasty, and he didn't want to get rich in the world.

How did you come to be in this era? I don't know. How do I go back and walk through again? I don't know.

What Li Dan knows is the fashionable phrase "live in the moment", being able to keep the safety of his aunt's whole family, this is the first, and then have the opportunity to take Meng'er back, these are the two most important things in his heart!

If it can be done, what more can the husband ask for? Even if he joined forces with the Han family and the Chen family to do the carriage and horse business, Li Dan also went to Beijing for the convenience of going to Beijing in the future.

He thought: Even if he needs 100,000 taels of silver to atone for his sins, he must smash open the big red palace gate of the Forbidden City to see the emperor and ask for forgiveness for Uncle Chen's family!

He saw Song Xiaoniu waiting there on the corner gate, and the master and servant went to the carriage and horse shop first.

The guy led them into the backyard, and saw a person in the wing room spinning around, but it was Chen Sanwen looking at the frame prototype (model) made by himself on the table.

"Yo, the third brother got up so early?" As soon as Li Dan spoke, he noticed the bloodshot in his eyes, and couldn't help but wonder: "What are you...... Haven't you slept all night? ”

Sanwen laughed as a default. Li Dan stumbled: "What's the trouble? ”

"Don't you have to be in a hurry? Besides, the faster I make this sample, the faster my father and brother will make drawings, select materials, and saw, and the construction period will be shorter. ”

He pointed to the sample: "It's just that I haven't figured out one thing, it's no problem for the front and rear two pairs of wheels to turn together, advance and retreat."

But you also know that this road is not flat, especially the further east you go, the mountain road is rough.

Such a large carriage is unusual for ordinary vehicles, and it is quite heavy in itself, plus the cargo, when encountering the front and back, or the height of the two sides is different, isn't the bump more than that of a two-wheeled car?

Even if it is loaded with dozens of stones, it will be broken to pieces, what can people do when they buy and sell? How to solve this problem, I didn't think about it overnight. ”

As he spoke, he picked up the cargo box that had been made next to him and put it on the frame.

"Hey, isn't this a carriage? I was just wondering what this was doing. ”

Saying that, Song Xiaoniu reached out and touched the front wheel, the gear mechanism drove the transmission shaft, and the back wheel also deviated in the same direction.

"Don't move the calf, this is what Chen Sanlang made overnight!" Li Dan's words frightened the calf into making a grimace, and he quickly rolled his hand and shrank to the side.

"The third brother is really an understanding person, and he can see the problem at a glance!" Li Dan was impressed, it turned out that there were also people with great vision in this era.

Chen Sanwen smiled and waved his hand: "Li Sanlang won the award, I just watched my father and brother do this since I was a child, and I was curious and loved to play and ponder by myself, how dare I dare to be the word 'understand'?" ”

Li Dan smiled, he searched his stomach and thought for a while, suddenly reached out and picked up the carriage to look at its bottom, leaned over to look at the frame for a while, and muttered:

"The terrain of the West is flatter than ours, and I am afraid that they have never thought that China will have so many mountains and rugged roads, so it seems that it cannot be copied, and it needs to be changed according to China's national conditions."

"Change? How to change? ”

Without immediately answering Chen Sanwen's question, Li Dan glanced around the room and saw that there seemed to be paper and pen on the table on one side, and immediately instructed Xiao Niu: "Grind ink, find a piece of paper to spread out." ”

As Maverick did the trick, he pointed to the bottom of the car and the frame and said, "We've got to find a way to put a shock absorber in between." ”

"Shock absorbers?"

"There are four points of contact between the carriage and the frame, and the pressure of the carriage will be conducted at these four points as much as it loads."

Li Dan walked to the table, picked up the pen, drew a rectangle, and tapped four dots to tell Chen Sanwen.

Just as he was about to continue, he frowned at the paper and instructed the calf: "Go to the shop and get a good piece of paper, and buy some good pen and ink." The calf agreed to go out and do it.

Li Dan first drew on the ready-made paper, he revised the original plan, connected the seat of the driver and the front end of the carriage to simplify, and then installed a shock-absorbing bow steel plate between the underframe and the axle sleeve.

"You see, each plate has a different size and bow force, and when it is squeezed from the upper compartment or the lower frame, the pressure is released layer by layer, so that the purpose of shock absorption can be achieved.

Wouldn't installing one of these shock absorbers at each of the four points take care of the front and back, left and right? ”

"Wonderful!" Chen Sanwen clapped his hands and shouted: "This is all solved, how did San Lang come up with it?" ”

"Where is the root of the problem? As long as it is solved, everything is solved at all! Li Dan put down his pen and pointed to the explanation:

"The bumps are because the wheel bushings are fixed directly to the underframe, so the unevenness of the ground is transmitted directly to the axles and the cabin through the wheels.

So if there is a certain design between the axle, the underframe and the carriage, like a quilt to delay this transmission, is there much less bump?

This is also the reason why when the woman goes out, the coachman is laying fur and quilts in the car!

It's just that this layer of foreshadowing is changed to a different form, and the shock absorber is moved to the base frame. ”

After he finished speaking, he asked, "Do you know what a spring is?" Seeing Chen Sanwen shaking his head, he picked up the sawdust from the ground, wrapped it around the pen barrel, and then stood the pen on the table:

"You see, when there is pressure on it, it squeezes down, the pressure disappears, the hand releases, it goes back to its original position, and so on.

If this thing is made of thick steel wire, one end is fixed in the carriage, and the other end is fixed in the underframe, does the people and goods above feel like they are hanging in the clouds, and they will not be too bumpy? ”

"It's extreme, it's extreme!" Chen Sanwen clapped his hands and shouted.

"In this way, there are shock-absorbing devices between the carriage and the chassis, between the chassis and the axles, even if you walk on mountain roads!"

"Ingenuity!" The two looked back and saw that it was Chen Gang's face flushed with excitement, his eyes shining, and Han An standing behind him with a smile.

Chen Gang stepped forward and said, "The old man originally had doubts, but now he has no doubts.

Li Sanlang is so talented, and he is devoted to Xiao'er, Chen Gang admires it. The owner is above, please be worshiped by the little old man! ”

As he spoke, Li Dan hurriedly returned the salute in a panic, helped Chen Gang up, and said:

"Since Dan is sincere and cooperative, there is no reason to hide his selfishness. The old shopkeeper can rest assured, Dan will teach him everything, and I believe that soon the three brothers will be able to understand it! Chen Gang was overjoyed and said goodbye.

The crowd immediately went to the front and invited three or five neighbors to testify.

The terms were confirmed on the three white deeds brought by Li Dan and copied, and since then the name has been changed to "Xingyuan Chexing".

Li Dan pressed his handprint on behalf of Xiao Qian's family, accounting for fifty percent of the shares, the Chen family accounted for three and a half percent of the shares, and the remaining one and a half percent belonged to the Han family, and Chen Gang and Han An also pressed their own handprints.

After eating and drinking, and giving the Witnesses money, everyone was happy and dispersed. Chen Sanwen continued to work on revising his samples.

Li Dan left the car dealership and came to the restaurant and called Liu Hongsheng and said, "What, how many people have you gathered?"

Sixteen? Okay, call them all, and borrow two more cars to go to the county government to load things.

Tell the eldest brother to get food for twenty people and send it to the back of the City God Temple. After saying that, he took the calf and left first.

Liu Hongsheng didn't know what to carry to the county office, but since San Lang said it, it should be a good thing.

Seeing that the time was almost noon, he hurriedly went to find someone, leaving two or three to help Liu Yuansheng get food, and the others went to the county office.

When he came to the door, he saw a large pile of weapons, and Song Xiaoniu stood next to him and couldn't close his mouth. Li Dan thanked Director Xiao in the barracks and walked out and greeted everyone with a smile:

"Don't be stunned, get on the car and transport it to the City God Temple, it's all for us!" The crowd cheered, and even the guards at the door laughed.

Li Dan was also happy, although these 120 people were still counted according to the Minfu team in the end, but Director Xiao won 240 taels of silver, and he had already got it in Beicheng, which helped Li Dan establish his authority to some extent.

After he left yesterday, Fan Xianling persuaded Zhao Jintang to gather the people of Nancheng to participate in the patrol at the head of the city within three days.

Li Dan gave an idea to Director Xiao, saying that each of the 120 people should be decorated with a complement in front of him and behind him, with the word "auxiliary" in front and the word "Yu Gan" in the back, and the black characters on a white background are relatively neat and imposing.

Director Xiao felt reasonable, so Li Dan asked him for three letters, and prepared to go back to find some women to make up for them.

It doesn't cost three hundred dollars to buy some white cloth and black cloth, but the women give three dollars for each person they make, and the total is only seven hundred dollars.

The important thing is that these people are distinguished from ordinary people when they have a complement, and even if they are pulled out, others will know that he is in this team, so that in case of bandits, they can distinguish between friend and foe.
