In fact, rolling bearings were not a new invention by Zhao Peng in this era. Bearings have a long history in China. As early as eight thousand years ago, China had ceramic sliding bearings. Later, because the bearings were used on vehicles, sliding bearings made of wood were directly used. Later, with the emergence of bronzeware, bronze sliding bearings appeared. In the Qin and Han Dynasties, vehicles used bronze sliding bearings and added grease to lubricate; after the Tang Dynasty, sliding bearings were made of cast iron; during the Yuan Dynasty, rolling bearings appeared.

However, in the Qing Dynasty, China's bearing technology, which was originally ahead of the West, was far behind the West. In the Westernization Movement in the late Qing Dynasty, Western rolling bearings were introduced to China, but the backwardness of the Qing Dynasty's steel technology made the rolling bearings produced by the Qing Dynasty use beads made of cast iron to bear the load. The consequence is that this kind of iron bead bearing is very easy to damage.

Just imagine, let alone trains, carriages, and cars, even if a bicycle uses cast iron bearings, it won’t take long to break the iron beads in the bearings.

Why do people have much worse impression of the Qing Dynasty than that of the Yuan Dynasty when they were also foreign races? Because one suppressed science and said science was a skillful silver skill, while the other developed science; one was a sick man in East Asia in the eyes of Westerners, and the other was a yellow peril in the eyes of Westerners. After the Yuan Dynasty inherited the industry and commerce of the Southern Song Dynasty, although the entry of the Semen people brought certain damage to the industry and commerce of China, the Yuan government did not suppress industry and commerce, but the Qing Dynasty directly banned the sea and closed the country, resulting in China being far behind the West since then.

Just imagine, if you want to change with the Yuan Dynasty, China would not be beaten so badly by the West.

Both Ming Heyou respected Confucianism, but the Yuan Dynasty simply canceled scientific research at the beginning, so scholars could only study science. Therefore, the science and technology of the Yuan Dynasty was not behind. Muskets and cannons were all born during the Yuan Dynasty. To this day, there are still crow guns at the end of the Yuan Dynasty in the arsenal of the Ming Dynasty.

Although the Ming Dynasty had already begun to lag behind the West in technology, the Ming Dynasty was a Han regime after all, and the Ming Dynasty was also catching up. The imitation firearms had reached the Western level. In other technologies, they were also catching up and not lag behind the West. However, the Qing army entered the pass, but interrupted the process of China.

In the late Qing Dynasty, although the Westernization Movement had been catching up with some in terms of technology, the Qing Dynasty was a barbarian regime after all, and the Qing rulers had never been on the same mind as the Han people. Defense of the Han Dynasty was better than defense of the barbarians. Those who violated our Qing Dynasty would have to pay compensation even if they were far away. In the Sino-French War, the Qing Dynasty won, but the treaty of the defeated country was still signed, let alone the Sino-Japanese War and the Eight-Nation Alliance. If it were not the Sino-Japanese War of 1894-1895, Japan would not have won the Sino-Japanese War. It was the reparations from the Sino-Japanese War that fattened up the evil wolf of Japan.

Not to mention the Qing Dynasty's hair shaving and clothing changes, literary inquisition, etc. that destroyed the Han culture. That's why there was such a saying: Wear the Qing Dynasty and do not rebel, and put on electric drills in chrysanthemums.

Although rolling bearings appeared in the Yuan Dynasty, the rolling bearings later returned to sliding bearings. The reason was that the early rolling bearings were very unreliable and the rollers were very easy to break. The carriages using rolling bearings were damaged and unusable for a long time, so they returned to the path of sliding bearings lubricated with grease.

However, the rolling bearings from hundreds of years ago have been abandoned for a long time and have been lost. What's more, the rolling bearings brought by Zhao Peng use modern styles of rolling bearings, so if there were no Zhao Peng's samples, Liang Xu would not be able to make rolling bearings by himself.

The rolling bearings brought by Zhao Peng are actually a catalyst for the development of Foshan's steel industry. When Liang Xu and Foshan people see the potential profits of rolling bearings, they will naturally vigorously develop the steel industry. When the steel industry develops, the military industry and the machinery industry will naturally develop, one by one, leading to the development of industrialization.

"Shopkeeper Liang, if this thing can be made and qualified spring steel can be made, I can help you produce a new type of vehicle to ensure it can be sold." Zhao Peng threw a bait to Liang Xu.

Liang Xu stood up and saluted: "Please give me a hundred thoughts, and the Cao people promise to make items that satisfy the Marquis!"

"We can save costs and change the roller bearing into ball bearings and put steel balls into the bearings, which is much cheaper than circular steel columns." Zhao Peng finally made a suggestion.

The weight of a four-wheeled carriage carrying passengers is not too large. Ball bearings can withstand the weight of a carriage. Roller bearings are suitable for use with heavier vehicles. For example, in future train bearings, roller bearings will be used.

The high-quality steel for manufacturing bearings, coupled with the spring steel for manufacturing vehicle suspension systems, has promoted the steel industry. High-quality steel can be used to produce machinery and weapons, and spring steel is a key component of flintlock guns and even future firing guns.

The emergence of bearings has also made the efficiency of water conservancy machinery higher, and it can use water conservancy machinery to produce more advanced machinery. With more advanced machinery, the steam engine can be born.

In fact, it is not many years before the Western powers began to lead the industrial revolution. In the original time and space, Britain had already begun to build a large number of hydraulic factories. Decades later, in 1698, the steam engine was also born. More than a hundred years later, Watt was not the inventor of the steam engine. He just improved the steam engine. The early steam engine could only be used to pump water. Watt's improved reciprocating steam engine could turn linear motion into circular motion, which led to the birth of trains and ships.

Industrialization is linked one after another. If you fantasize about developing industrialization under the conditions of nothing, it is simply a dream. With a certain foundation, you can develop on this basis and develop to a certain level, and then develop on this basis and accumulate layer by layer, and finally the industrial revolution can be born.

Liang Xu made a promise, so he summoned several workers and began to smelve high-quality steel. Zhao Peng brought three carpenters and two blacksmiths to build a four-wheeled carriage.

Three carpenters built the carriage based on Zhao Peng's design drawings, while Zhao Peng personally led the blacksmith to build the car frame. The frame of the four-wheeled carriage is the key. The front two wheels are relatively small and are responsible for the steering function. The rear two wheels are large and are responsible for supporting the carriage.

Under the guidance of Zhao Peng, the blacksmith bent the thick iron sheet to form a "several" frame, and then welded the frames, first made into a rear auxiliary frame, an iron frame extending forward from the main frame, and to the end, drilling a hole, and then connecting the axle of the front frame and the rear frame with this hole. The front frame can rotate, while the rear frame is fixed.

Two blacksmiths took two days to prepare the frame, and Liang Xu also brought several workers to build four rolling bearings, twelve spring steel strips and four pairs of spiral springs.

Zhao Peng got the bearing and spring steel strips, and he was still very satisfied with Liang Xu's craftsmanship. Next, he installed the bearing on the axle, then combined the three spring steel strips into one piece, and installed them on the axle. A flexible connection was adopted between the axle and the frame, so that the car could reduce vibration in the car while walking.

The wheels are then mounted on the bearings, and the completed carriage is then placed on the frame.

The carriage and the frame are not directly fixed with bolts. Put four spiral springs on the frame and then fix the carriage on the four springs.

It took a total of three days before and a brand new four-wheeled carriage was completed.

When the test drive was coming, Liang Xu got on the four-wheeled carriage with curiosity. A craftsman acted as a coachman, sat in front, driving two horses to run and pull the carriage.

The four-wheeled carriage was walking very fast. The two horses pulling the carriage were obviously very relaxed. The horse ran happily with its hooves. Liang Xu, who was sitting in the carriage, saw the carriage driving on the uneven stone road with his own eyes, but when he was sitting in the carriage, he felt that the vehicle was not vibrating much, and he felt as stable as if he was sitting in a sedan.
