  Chapter 20 The difference between spoke wheel and spoke wheel

  Out of the inspection field, Liang Hongjun talked and laughed and led Ma Jian and Zhao Guoyang to the three-story building of the Technical Quality Department.

  Liang Hongjun's office is in the innermost part of the third floor, and the one outside is the office of Vice Minister Wang Hongxi.

   When he passed by, he saw that there was no one inside, so Liang Hongjun didn't say anything. He gave a few words to a technician who passed by, and then led them to his office.

  After being seated, Liang Hongjun poured a glass of water for Ma Jian and Zhao Guoyang himself, and started chatting.

  The two leaders chatted all over the world, Zhao Guoyang naturally didn't want to interrupt, and only said a few words when Liang Hongjun asked him.

Seeing that Zhao Guoyang seemed a little reserved, Liang Hongjun smiled and said: "Xiao Zhao, I guess you are not interested in the topic we are talking about. Leave us alone and read the newspaper for a while. When Minister Wang comes back, let's talk again." Let's talk about work."

  Zhao Guoyang secretly laughed in his heart, but he didn't refute the words of the two leaders. He sat down honestly and picked up the newspaper on the table and read it.

   Just after reading it for a while, an article in this newspaper caught Zhao Guoyang's attention.

   This is a large newspaper in the machinery manufacturing industry, called "Made in China".

  Zhao Guoyang in his previous life was very familiar with this newspaper. He also accepted an exclusive interview with this newspaper and wrote several special articles with unique insights.

  Basically, many of the most advanced technologies in the domestic manufacturing industry were first exposed in the newspaper "Made in China".

  Seeing the newspapers and periodicals he was so familiar with at this time, Zhao Guoyang naturally became interested.

  He also wanted to know what was the level of the domestic machinery manufacturing industry in the early 1990s.

  He quickly glanced at the main page of this newspaper, which basically talked about the advanced management methods of foreign large-scale machinery manufacturers, with little involvement in technology.

   It is no wonder that at the current stage, the blockade of China by Western countries has not been fully lifted, and many technologies are still kept secret from China.

  In a corner of the sub-page, an article signed by Xiangxi Sanyuan Welding Material Factory, Zhang Fugen's article fell into Zhao Guoyang's eyes.

  Because the world after rebirth may not be exactly the same as the original one, Zhao Guoyang really doesn't know who this Zhang Fugen is.

  But Zhao Guoyang is very familiar with the welding materials factory in Sanyuan City, Xiangxi Province.

   This small factory, which looks inconspicuous now, is the predecessor of Wuyi Heavy Industry, the largest construction machinery manufacturer in China in the future.

  In the era before Zhao Guoyang's rebirth, Wuyi Heavy Industry had developed into the fifth largest construction machinery manufacturer in the world and the largest concrete machinery manufacturer in the world. It was definitely a behemoth in the domestic machinery manufacturing industry.

  The current Wuyi Heavy Industry is undoubtedly not yet established, but this article is definitely of some reference value.

  Because if Zhao Guoyang remembers correctly, the Sanyuan City Welding Material Factory in Xiangxi Province will soon be renamed Wuyi Group Co., Ltd.

   In other words, the establishment of "May Day Heavy Industry" has entered the countdown.

  Perhaps, this article is a throwback to this ambitious enterprise, hoping to attract the attention of high-level technical personnel in the industry.

  This article is about the difference between spoke wheels and spoke wheels.

  First of all, explain the concept of the panel. The disc used to connect the rim to the hub is called a web. Most of the spokes are stamped, and some are cast.

  The steel plate used for the wheel spoke plate of a car is relatively thin, and it is often stamped into an ups and downs shape to improve rigidity.

  In order to reduce the weight of the wheel and accelerate the heat dissipation of the wheel hub, some cars are mostly made of aluminum alloy casting. In order to ensure the balance performance of high-speed driving, a balance block is added to the spoke plate.

  The rim and web are welded together and bolted to the wheel hub or brake drum to form the wheel.

  The wheel is dynamically balanced with a balance weight, and the wheel decoration cover is installed outside the spoke plate, which constitutes the entire structure of the spoke plate wheel.

   Spoke wheels are much simpler. The spokes of this wheel are steel wire spokes or cast spokes that are integrally cast with the hub. Wheels include rims and hubs in one piece.

  The difference between the two is obvious.

  Because of the high price and inconvenient maintenance and installation of steel wire spoke wheels, foreign countries have gradually eliminated them.

  It is only used in racing cars and some high-end cars, such as the Lincoln sedan produced in the United States, which still uses spoke wheels.

   In addition, there is a special cast spoke wheel, which is usually used for heavy-duty vehicles with a large load.

  Although the article makes a little mention of this cast spoke wheel, Zhao Guoyang believes that this technology must have been mastered by the Sanyuan Welding Material Factory.

  After talking about the advantages and disadvantages of the two types of wheels, the topic of the article changed, and I began to think about the possibility of the application of spoke-plate wheels in the motorcycle industry.

  In fact, if Zhao Guoyang remembers correctly, this technology was already used by Huaxia manufacturers as early as a year ago, that is, in 1990.

  In the memory of his previous life, in 1990, Changnan Aircraft Manufacturing Company of Ganzhou Province launched the Changjiang CJ750 new three-wheeled motorcycle, and its rim used a web-type structure.

   Just because it is not a regular two-wheeled motorcycle, this innovation has not attracted attention in the industry.

  After the company in Changnan City used the new technology of spoke-plate wheels, it not only eliminated the trouble of frequent adjustment and threading of spoke-type rims in the past, but also greatly improved the convenience of maintenance.

   This point is also the focus of this article.

  After reading this article carefully, Zhao Guoyang still has some ideas.

  In his opinion, if this article can be taken seriously by industry experts, it will definitely improve Huaxia's motorcycle production technology to a higher level.

  In addition, on large machinery, this technology is also useful.

  For example, large-scale rice transplanters and harvesters used in agriculture can greatly improve production efficiency if spoke-type wheels are used.

   It’s just, judging from the space occupied by this article and the position of the layout. At least in the eyes of the editor of "Made in China", its importance does not seem to be high.

   Such a discovery made Zhao Guoyang secretly sigh.

  Sometimes, it is not that China, a great country, lacks innovation and development, let alone lacks talents. It is just that it is neglected or buried because of bad luck.

   Just as Zhao Guoyang was sighing over there, there was a knock on the door of Liang Hongjun's office.

   Then, a middle-aged man who looked like a leader walked in, wearing a gray Chinese tunic suit with a 30-70 cut.
