Chapter 1147

Since you want to make a carriage, then make high-end goods first. After all, carriages made with shock absorbing devices such as springs naturally have to go on a high-end route before they can be sold at a price.

Not only does it require the installation of shock-absorbing springs, but also metal bearings need to be used to increase durability and wear resistance. At the same time, a large number of metal parts are adopted, which not only makes the carriage stronger, but also reduces the weight of the carriage.

"...This is, huh, I don't feel right. The carriage you designed is actually four wheels?"

"Yes, I'm going to want to manufacture, or the fist products of the vehicle workshop we are going to set up, are this kind of four-wheeled carriage. In the past, there were no good enough transportation conditions, and the most practical one was the two-wheeled carriage because it could drive under rough terrain conditions. But now the industry is different..."

"Although the main traffic in our Song Dynasty is still mainly yellow dirt roads, there are several very important traffic roads that have become straight and smooth, and very solid and flat cement straight roads. There is no pressure to use a four-wheeled carriage on such roads."

The advantage of four-wheeled vehicles is that they have large load capacity and stable operation. The disadvantage is that four-wheeled vehicles need to drive on a relatively flat road surface. Wang Yang remembers that the Roman Empire in the West paid great attention to the construction of road traffic.

This is why there is a proverb like a road leading to Rome. The Roman Empire built nearly 80,000 kilometers of flat avenues at its peak, making this kind of four-wheeled carriage very popular.

The roads built by these Romans are very strong and durable. For military avenues and important trunk lines, four-story paving methods are generally adopted.

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

The last layer is paved with chiseled flat stones or gravel, and is slightly raised in the middle to facilitate rainwater to flow to both sides. For secondary or private roads, surface paving may be eliminated.

After the fall of the Roman Empire, the roads gradually collapsed after centuries of disrepair. The most practical one at this time was a two-wheeler because it could drive under rough terrain conditions.

Today, after years of construction, the Song Dynasty has built a cement straight road of more than 20,000 miles long. Now, all roads in the city of Bianliang in Tokyo have been transformed and hardened, which is very suitable for driving a four-wheeled carriage.

From Tokyo Bianliang to Chang'an, from Chang'an to Yan'an Prefecture, and even to Yanzhou, Youzhou and other places on the north Shaanxi road. Continue to go west, Qinzhou, where Qinfeng Road has been built.

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

To the east, the Suzhou area has been built to Huainan East Road southeast of Yingtian Prefecture. To the south, the Suzhou area has been built to arrive at Yingchang Prefecture.

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

"Compared with the principle of a four-wheeled carriage, the principle is more stable and the load will be higher, because the load bearing is completely handed over to the carriage itself. The horse only needs to use the power of pulling forward, without having to bear the weight of the carriage..."

Following Wang Yang's explanation, Wan Bin was confused. "Although my foolish brother Lu Du and doesn't understand very well, he sounds very powerful."

"...It doesn't matter. Let's buy a carriage shop first, and then I will supervise it myself. Once you have the real thing, you will understand." Wang Yang rubbed his eyebrows helplessly. It was really difficult to communicate with these guys who don't have much knowledge of physics and chemistry. It seems that only by taking out the real information and letting them see it is real.

Wan Bin bought a carpenter workshop that used to specialize in making ox carts and donkey carts. However, the industry has been renamed. The wealthy Wanhong Group not only bought this carpenter workshop, but also the craftsmen who originally worked in the Chen family carpenter workshop have also signed contracts again.

The wages increased by 30% compared to before. The dozens of craftsmen in this carpenter workshop smiled and were naturally full of energy.

Wang Yang not only brought the drawings, but also personally provided guidance on the spot. In just five days, a brand new and very beautiful four-wheeled carriage appeared in front of Zhao Ji, Wan Bin, Li Yu and others.

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

"It should be possible... you can't turn. So what's the use of such a carriage even if it's load-loaded?" Wan Bin said with a deep expression of agreement.

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

"So that's it. I didn't expect that the teacher not only had great theory, but also did it. Otherwise, he could design so exquisitely..."

Wang Yang next to him was commanding Wu Qilang and Wang Jing to put on harnesses there. Of course, he was the one who was Wang Daguanren’s own mount.

And the craftsmen who participated in the production of this four-wheeled carriage were standing aside with eager and anticipated eyes.

After getting ready, Wu Qilang jumped to the front row where the groom was riding, and quickly lifted the reins.

"Wait a moment, let me go up and try it." Before Wu Qilang could whip the horse, Zhao Ji, who had just maintained a vulgar squatting position, jumped up and flexibly jumped onto the carriage and sat down.

"You two, do you want to try it too?" Wang Yang also stepped onto the carriage and raised his hand to Wan Bin and Li Yu.

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

"Don't worry, Wang Jing, you go up to the front and sit with Wu Qilang. You two hurry up, and Ling Zong, stand behind..." After Wang Yang and the two of them got on the carriage, they closed the unpainted car door, and then walked towards Ling Zong who was standing beside him, who was eager to try.

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

"We have seven people here, and only one horse can really pull it?" Not to mention that it was a guy like Wan Bin who lacks math, physics and chemistry knowledge, even Zhao Ji couldn't help but look shocked at this moment.
