Datang romantic little landlord

Then the only way is to find a way to transport this thousand stones of grain to Yinzhou.

But he asked Yang Zuan just now that Yinzhou has no waterways, so shipping is impossible, and the only way to transport is by land, using ox carts or horse-drawn carts.

With Datang's current ox cart transportation capacity, that's it. The horse cart is faster, but the load capacity is not good.

He patted his head depressedly, hoping to come up with a solution to the current predicament.

Su Changqing looked worried: "Wangyou, don't think about it, let's go to Uncle Cheng to intercede."

Li Wangyou thought about it for a long time, and really felt that there was no other way, so he could only sigh, and nodded silently.

He ordered Niu Wu to lead the horse, and the two rode on to go to Chang'an City for help.

Not long after leaving the entrance of Dingzhou Village, a carriage came towards him. Because the road was not wide, Li Wangyou and Niu Wu pulled his horse and stood aside, waiting for the carriage to pass first.

The carriage creaked and passed by them, and the handlebars nodded to the two of them in a friendly manner to express their gratitude.

After the carriage passed, Niu Wu pulled the rein and was about to push the horse forward, but he saw Li Wangyou sitting on the horse without moving, staring at the receding carriage, thinking about something.

"Lang Jun, what are you thinking? Let's go." Niu Wu urged.

Li Wangyou didn't speak, just stood there in a daze.

When Niu Wu was wondering, he saw Li Wangyou pull the rein suddenly: "Niu Wu, let's go back! I have a solution! Haha, I am indeed a genius!"

Li Wangyou didn't wait for Niu Wu, so he rode his horse and galloped towards the village. Niu Wu couldn't figure it out, so he had to turn his horse's head to follow.

Seeing Li Wangyou go and come back, the beautiful boss couldn't help but wonder: "Wangyou, why are you back?"

Lao Cunzheng and Yang Zuan were still in the main house of the Li family, and they were also very surprised to see him return suddenly.

"Haha, Changqing, I have a solution! As long as the four-wheeled carriage is built, the thousand shi grains will not be a problem!" Li Wangyou jumped off the horse and shouted loudly.

"Four-wheeled carriage?" Su Changqing didn't understand what he meant.

Lao Cunzheng and Yang Zuan were also confused by Li Wangyou's words, what is this four-wheeled carriage?

Four-wheeled carriages have been rare in China since ancient times, but four-wheeled carriages did appear in the Song Dynasty, as shown in the "Riverside Scene During the Qingming Festival".

However, that kind of four-wheeled carriage is different from the western ones. Its four wheels are installed on a fixed frame, so it cannot be steered. The steering problem is solved by the strength of the four oxen.

That's right, this is the reason why Huaxia's carriages and ox carts have two wheels since ancient times, and bogies have not been invented!

Four-wheeled carriages with bogies have appeared in the West since the Roman era, while the East has indeed taken a detour in this regard.

When Li Wangyou saw the Tang carriage just now, he always felt that something was wrong. After thinking about it for a long time, he suddenly realized that it was because the Tang carriage and the ox cart only had two wheels.

In terms of load, the four-wheeled carriage completely exploded the two-wheeled carriage.

Li Wangyou remembered that the Napoleon Legion in Europe relied on four-wheeled carriages to solve the problem of military transportation. At that time, each four-horse carriage carried a load of [-] tons!

It is equivalent to a four-wheeled carriage that can carry thirty stones of grain, and a thousand stones of grain can be easily pulled away by more than 30 four-wheeled carriages.

Moreover, the speed of the four-horse carriage is far faster than that of an ox cart.

The bullock cart can only travel seven or eight kilometers per hour, while the speed of the horse-drawn cart can reach about 160 kilometers.Calculated based on the carriage traveling for four hours a day, that is [-] kilometers.It only takes about three days to go from Chang'an City to Yinzhou.

"Mingfu, when did Sihu join the army and ask us to leave?" Li Wangyou asked, he needed time to gather people to try out the carriage.

"Depart from Chang'an City in five days."

"Can the cattle transporting grain be replaced by draft horses? I need more than 100 draft horses." Li Wangyou asked again.

Yang Zuan frowned: "Of course it's okay. After all, cows are more valuable than horses. Don't tell me you want to use a horse-drawn cart to transport grain? Horses are not as strong as cows."

"Yeah, Xiao Lang, this is not a joke. A horse-drawn cart can only pull five or six shi of grain, and an ox cart can pull nearly ten shi. If a horse-drawn cart is used, the number of people in the village will need to be dispatched. You can't do it." Old Village also quickly persuaded.

"Haha, don't worry, I can build a carriage that can pull thirty shi of grain! I'm going to find Carpenter Liu now!" After Li Wangyou finished speaking, he turned and ran out.

His words made Yang Zuan and Lao Cun look at each other head-on. Could it be that the young man of the Li family has lost his mind?

Thirty stones of grain in a carriage?How can this be!

Even an ox cart pulled by four oxen cannot carry so much, let alone a horse.

"Mingfu, look at the matter..." Ai Ai of the old village Zhengqi looked at Yang Zuan, hoping that he could persuade Li Wangyou.

This matter is related to the life and death of the whole village of Dingzhou Village, so it cannot be left to the Li family's Xiaolang's temper.

On the other hand, the beautiful boss at the side understood Li Wangyou's words, and his eyes lit up.Although she didn't know how much goods the four-wheeled carriage could hold, she knew that the four-wheeled carriage eliminated two carriages, and when she traveled abroad in later generations, she also made that kind of four-wheeled carriage to solicit tourists for sightseeing.

Two healthy horses can pull a dozen tourists around, which is much more powerful than Datang's ox carts.

Yang Zuan and Lao Cunzheng naturally didn't know this. After Li Wangyou ran out, the two of them were restless, and they couldn't figure out what Li Wangyou wanted to do.

Letting Lao Cunzheng lead the way, the two also walked to Carpenter Liu's house, preparing to see for themselves what Li Wangyou's "four-wheeled carriage" was.

At Carpenter Liu's home, Li Wangyou was busy with a charcoal pen, writing and drawing on paper, talking to Carpenter Liu while writing and drawing, and Carpenter Liu's three sons were watching from the sidelines.

Yang Zuan and Lao Cunzheng didn't know why, so they could only stand by and watch.After a long time, Li Wangyou finally put down the charcoal pencil, and Carpenter Liu and his three sons all looked excited when they heard this.

"Xiao Lang, you really are a literary star descending from the sky! You all know about such fetishes! I will try it out with my son right away. If it succeeds, Xiao Lang, you are another great achievement for the benefit of all people!" Carpenter Liu sighed. .

116 Four-wheeled carriage II

In fact, the four-wheeled carriage is not complicated, the key lies in the steering mechanism.

The steering mechanism is not difficult, just a layer of window paper, once it is broken, it will no longer be mysterious.

The front axle of the wagon is connected to the chassis by a rotating pivot so that the front wheels can turn.

The front wheels of the carriage are smaller than the rear wheels, and the front wheels are responsible for steering, while the rear wheels bear the weight.

Since it is four wheels, the load capacity of the vehicle itself will be higher than that of two wheels, there is no doubt about it.

As for the shock-absorbing and shock-absorbing springs of the carriages of the later generations, Li Wangyou didn't have extravagant hopes. Anyway, it was a carriage used to pull goods, so there was no need to consider any comfort issues.

The reason why he knew the structure of this carriage was not surprising. There was a cooperative carriage in the village when he was a child.

The favorite of a few brats is to ride in a carriage, and the carriage has broken down several times. Every time it is being repaired, Li Wangyou will watch eagerly from the sidelines, come and go, and figure out what is going on with the carriage .

Carpenter Liu and his three sons are really good at their craftsmanship. In addition, there are helpers in the family who build ox carts, and the wheels are ready-made.

He took his three sons with him, and within an hour, he processed a set of steering gear for a carriage out of wood, found the chassis of an ox cart, and installed it.

Not long after, the simple version of Datang's first four-wheeled carriage was built. Because it was temporarily modified with the chassis and wheels of the bullock cart, it looked a bit weird.

Lao Cun was walking around the "four-wheeled carriage" a few times, with a look of disbelief: "Xiao Lang, this is what you said, a carriage that can pull thirty stone? Don't worry, it's impossible."
