Nanming: I can build wonders

Chapter 306 Daming Brand "Rolls-Royce" Something Happened to the North (Subscribe!)

"Right, that is it."

Zhu Kezang held a stack of steel rods that were just made by the craftsmen that became shorter and slightly warped from bottom to top, and nodded with satisfaction.

"Then rivet the middle of the spring piece, and add an iron frame every half a foot to fix it."

"Yes, the little one will do it." The leading craftsman hurriedly responded.

The parts were made yesterday. Several craftsmen skillfully punched holes in the steel bars, riveted them, and installed the fixed frame. An [-] cm long leaf spring soon took shape, which was similar to the common ones on later generations of cars. The shock absorbers are quite similar.

The craftsmen of the Ming Dynasty Manufacturing Bureau can more or less know Braille, can understand industrial drawings, and have undergone standardized training in craftsmanship, but Zhu Kezang, the emperor of micro-manipulation, is still a little worried.

So, Zhu Kezang guided them hand in hand for two days, and Daming's first car shock spring soon took shape.

Of course, this is for the carriage.

In fact, the structure of this steel plate damping spring is very simple, that is, several layers of steel plates are riveted together, and a certain degree of warpage is left.

A skilled blacksmith can make several pairs a day.

However, although this thing is simple, it is the best structure optimized by people of later generations after repeated improvements. It has never appeared in the seventeenth century, and it definitely belongs to the high-tech of this era.

In addition, the steel damping spring has extremely high requirements on the material. If it is made of ordinary iron, it will not only have extremely poor elasticity, but will also break after a short period of time.

In order to build this thing, Zhu Kezang specially sent high-quality steel from Chengtianfu Steel Plant to solve the material problem.

On the other side of the factory, craftsmen are installing a "big wooden box" on wheels, and the work is obviously coming to an end.

There is a shaft in front of the wooden box, and the wheels are as high as half a person. It is the carriage of a carriage.

Different from the two-wheeled carriages commonly used in the Ming Dynasty, this cart has four wheels, which are mounted on the frame through two axles.

The most unique thing is that the front and rear of the frame are separated and connected together by a longitudinal axis, along which the two front wheels of the car can swing left and right.

This is a standard four-wheeled carriage!

Four-wheeled carriages have many advantages over two-wheeled carriages, such as two or three times the load capacity, no need for horses to struggle to maintain horizontal balance, smooth driving, and so on.

However, due to the fact that the turning radius of the wheels on the left and right sides is different when the four-wheel vehicle is turning, if the wheels are directly installed on the carriage, it will cause the embarrassing situation that the outer wheels are stuck on the ground when turning.

Fortunately, this problem can be solved with a simple frame steering knot. In layman's terms, the front axle is separated independently and connected to the frame with a longitudinal axis. When turning, the front and rear wheels deflect independently, and the slip problem is naturally eliminated. .

In fact, there have been vehicles with this structure in China in history, and they were mostly used as large freight vehicles.

However, due to the good adaptability of two-wheeled vehicles to uneven roads and low cost, two-wheeled vehicles have always been the first choice of Orientals, and the steering structure of four-wheeled vehicles has gradually been lost.

Due to the needs of moving the capital and transporting goods this time, Zhu Kezang took the craftsmen to trial-produce a four-wheeled carriage.

By the way, the container has already been successfully developed under the auspices of Huang Luzhuang. The new four-wheeled carriage was developed to fit the container.

In terms of transporting heavy goods and saving the physical strength of horses, four-wheeled carriages have great advantages. If they can take advantage of this opportunity to start mass production, they will also play a great role in military logistics in the future.

Moreover, Zhu Kezang's four-wheeled carriage also has "black technology" far beyond the West, that is, shock-absorbing springs and rubber wheels.

You know, the carriages of this era are all wooden wheels, which are directly mounted on the carriages with the axles, and there is no asphalt road, the bumps when driving can almost shake people apart.

In comparison, a car equipped with steel shock absorbing springs and rubber tires can filter out [-]% of the bumps. Although it is only a solid soft rubber tire, the ride comfort will definitely "kill" any carriage in this era.

In addition, the four-wheel structure is relatively stable in the horizontal direction, and the car body is more spacious. Even as a "sedan", it is a good choice.

It can be said that the carriage he ordered the craftsmen to build is the "Rolls-Royce" of the new Ming Dynasty!
Of course, the four-wheeled carriage also has its own disadvantages, that is, the passability is not as good as that of the two-wheeled carriage.

However, this car is mainly aimed at the "luxury car" market in big towns, and there is no problem in this regard when used in bustling cities.

In addition, according to Zhu Kezang's Daming infrastructure plan, the post road will be rebuilt according to the "highway" standard in the future, so the scope for the four-wheeled carriage to flex its muscles will be even greater.

"If you want to get rich, build roads first", Zhu Kezang has heard this sentence since he was a child. Convenient transportation is the fulcrum of economic development, and he is absolutely devoted to this aspect.

The railway has been relatively complete in Yizhou Island, but the cost of introducing it to China is too high, so it is better to build roads first.

It is conceivable that after a few years, "railways" and "highways" will be spread all over the land of Ming Dynasty. Whether it is the development of industry and commerce, or the mobilization of troops and logistics, and even communication, tourism, etc., will benefit from this and become Very convenient.

Zhu Ke Zangzheng told the craftsmen how to install the shock absorbing spring on the frame, and a guard came to report, "Your Majesty, the craftsmen of Chengtian Mansion have entered the city."

"It's finally here." Zhu Kezang showed a relaxed smile, and the manpower was finally in place. The number of craftsmen who had migrated earlier was too small to be enough.

"Let them settle down and come here to build a carriage together. The samples have already been prepared for them."

The site that Ying Tianfu gave to the General Manufacturing Bureau was the original Nanjing Military Bureau.

Although the scale of the Nanjing Military Bureau is large, it is still an old-fashioned manual workshop model, which is incompatible with the "advanced productivity" of Ming Dynasty.

Zhu Kezang considered that there should be no military pressure on Chengtianfu in the future, so he simply transferred all the technical backbones of the Ming Manufacturing Bureau to Yingtianfu.

With the nearly four-mile-long sheds and more than [-] craftsmen of the Nanjing Military Bureau, once the industrial standardization transformation is completed, a terrifying production capacity will explode. Almost his family can take on [-]% of the weapons manufacturing work of the Ming Dynasty.

After the guards who sent the order left, the old eunuch Li brought over tea again, "Your Majesty, take a rest. It's already noon, do you think you should go back to the palace for lunch first? I have to go to the shipyard in the afternoon..."

"Back to the palace?" Zhu Kezang frowned. The east of the palace city and the Longjiang Treasure Shipyard are to the north. It would be a waste of time to go back and forth.

In the afternoon, he will also inspect the Longjiang Treasure Shipyard. This treasure shipyard is not simple. It is the "birthplace" of Zheng He's treasure ships that sailed to the West more than 600 years ago.

"Don't bother, just eat on the spot."

Just when Zhu Kezang was about to eat, another guard handed Zhu Kezang a letter box sealed with wax, "Your Majesty, this is the information just sent by Jin Yiwei."

As soon as Zhu Kezang opened it and saw the contents, he said with a smile, "Haha, it's fun to watch from the north again!"
