Chapter 1147

Since you want to make a horse-drawn carriage, then you must first make high-end goods, after all, a horse-drawn carriage made of shock-absorbing devices such as springs naturally has to take the high-end route before it can be sold at a price.

Not only should shock-absorbing springs be installed, but also metal bearings should be used to increase durability and wear resistance, and at the same time, a large number of metal parts should be used, which can not only make the carriage stronger, but also reduce the weight of the carriage.

“…… This is, hey, I don't feel right, this kind of carriage you designed is actually four wheels? ”

"That's right, the fist product of the vehicle workshop that I am going to build, or that we are going to set up, is this four-wheeled carriage. In the past, there were not enough good traffic conditions, and the most practical thing was a two-wheeler, because it could drive in rough terrain conditions. But now the industry is different......"

"Nowadays, the main traffic in my Great Song Dynasty, although it is still dominated by yellow dirt roads, there are several very important traffic arteries, which have become straight and smooth, and they are very strong and smooth cement straights, and there is no pressure at all to use four-wheeled carriages on such roads."

The advantage of a four-wheeled vehicle is that it has a large carrying capacity and runs smoothly. The disadvantage is that the four-wheeled carriage needs to be driven on a relatively flat surface. Wang Yang remembered that the Roman Empire in the West attached great importance to the construction of road transportation.

This is where there is the proverb that all roads lead to Rome, and the Roman Empire built nearly 80,000 kilometers of flat avenues at its peak, making this kind of carriage very popular.

The roads built by the Romans were very strong and durable, and for the military avenues and important arterial routes, they were generally paved in four tiers.

The excavation depth can generally reach 1 to 1.5 meters, and the lowest layer is made of some small stones, mortar or clay as the foundation; the second layer is impervious layer, which is mixed and compacted with small pebbles, gravel, bricks and concrete; The third layer is laid on the foundation with high-quality concrete mixed with lime, sand, cement, and compacted with a machine.

The final layer is paved with chiseled or flat stone or gravel, with a slight convex middle to allow rainwater to flow to both sides. For secondary or private roads, surface paving may be omitted.

After the fall of the Roman Empire, the roads fell into disrepair over the centuries. The most practical at this time is the two-wheeler, as it can be driven in rough terrain conditions.

Today's Great Song Dynasty, after several years of construction, has built more than 20,000 miles of cement straights, and now, all the roads in Tokyo Bianliang City have also been renovated and hardened, which is very suitable for four-wheeled carriages.

From Tokyo Bianliang to Chang'an, from Chang'an to the north to Yan'an, and even to Yanzhou, Youzhou and other places in the north of Shaanxi. Continuing to the west, it has been repaired to Qinzhou on Qinfeng Road.

If you start north from Bianliang, Tokyo, you can directly reach Taiyuan Mansion on Hedong Road, and the cement straight road to Zhending Mansion on Hebei West Road is also nearing completion.

To the east, the land of Suzhou that reached the Huainan East Road southeast of Yingtianfu has been built. To the south, it has also been built to reach Yingchang Mansion.

With so many miles of cement straights, this is the reason why Wang Yang decided to develop a four-wheeled carriage.

"Compared with the two-wheeled carriage, the principle of the four-wheeled carriage is more stable and the load will be higher, because the load bearing is completely handed over to the carriage itself, and the horse only needs to exert the force of pulling forward, and does not need to bear the weight of the carriage......"

With Wang Yang's explanation, Wan Bin listened with a confused expression. "Although the foolish brother is reckless and doesn't quite understand, it sounds like a powerful look."

“…… It doesn't matter, let's buy a car and horse shop first, and then I'll personally supervise the construction, and when we have the real thing, you will understand. Wang Yang rubbed his eyebrows helplessly, it is really difficult to communicate with these guys who don't have much knowledge of mathematics, physics and chemistry, it seems that only by taking out dry goods and letting them see is believing.

#####

Wan Bin bought a carpenter's workshop that used to specialize in making ox carts and donkey carts, but now that the industry has changed its name, the wealthy Wanhong Group not only bought this carpenter workshop, but also re-signed the contract with these craftsmen who originally worked in Chen's carpenter workshop.

The salary has increased by 30% compared to the original. Let the dozens of craftsmen in this carpenter's workshop smile one by one, and they are naturally full of energy.

Wang Yang not only brought the drawings, but also personally guided the scene, in just five days, a new and very beautiful four-wheeled carriage prototype appeared in front of Zhao Ji, Wan Bin, Li Yu and others.

"It's really four wheels, but can four wheels really turn?" Li Yu touched the short beard on his chin, and muttered to Wan Bin beside him with a puzzled expression.

"I guess it's okay...... If you can't steer, then what is the use of such a carriage even if it is heavy? Wan Bin also said with a deeply appreciative expression.

As for Zhao Ji, at this moment, His Royal Highness Duan Wang was squatting on the ground regardless of his image, and his eyes full of curiosity and freshness were falling on the connection between the first two wheels of the four-wheeled carriage and the carriage chassis, and he was amazed there.

"I see, I can't imagine that Mr. is not only theoretical, but also practical, otherwise, such a delicate design......"

Wang Yang next to him was directing Wu Qilang and Wang Jing to put on the harness there. The one used is naturally the mount of his own king's officials.

And the craftsmen involved in the production of this four-wheeled carriage are standing by with eager and expectant eyes.

After getting ready, Wu Qilang jumped into the front row of the groom in front of him, and quickly lifted the reins.

"Wait a minute, let me go up and try it." Before Wu Qilang spurred the horse, Zhao Ji, who had been maintaining an obscene squatting posture, jumped up, flexibly jumped into the carriage and sat down.

"You two, why don't you go up and try it too?" Wang Yang also stepped into the carriage and raised his hand towards Wan Bin and Li Yudao.

"This, can this be moved?" Li Yu and Wan Bin couldn't help but peep at each other.

"Don't worry, Wang Jing, you also go up to the front and sit with that Wu Qilang, you two also hurry up, and Ling Zong, you stand in the back......" Wang Yang waited for the two brothers to also get into the carriage, closed the unpainted door, and then walked towards Ling Zong, who was standing on the side with an eager look.

Ling Zong was overjoyed, and after agreeing, he jumped directly to the back of the carriage.

"We have seven people here, and this is just one horse, can we really pull it?" Mo said that it was a guy like Wan Bin who lacked knowledge of mathematics, physics and chemistry, even if it was Zhao Ji, he couldn't help but be stunned at the moment.

Seven big men, one person is calculated as an average of one hundred and fifty catties, which is more than a thousand catties, plus the weight of the carriage itself, how can there be a thousand catties, that is, more than two thousand catties, Wang Yang is not afraid of crushing his own backbone.
