Will the automotive gear industry decline?

At present, the development of electric vehicles is in full swing. Electric cars are powered by onboard power supplies and are driven by electric motors, reducing gear usage compared to conventional cars. Some people have asserted that the automotive gear market will shrink.

Will the auto gear market really shrink? At the 2016 International Conference on the Industrialization of China's Auto Transmission, the reporter interviewed relevant experts with this question.

Sayuki Suzuki, a senior expert in technology integration at Japan's Gutco Co., Ltd., said: “In the past, the automobile has become more popular and there has been some increase in gear usage as the gear has been increased. Although the structure of the transmission part of the electric passenger car is extremely compact, only The ability to fit single-stage automatic transmissions has resulted in a reduction in the amount of gear used, but large-scale vehicles are not suitable for electrification and their gear usage will not be reduced. It will only lead to a drop in the overall automotive gear usage and will not cause the entire automotive gear market to shrink."

Automobile electrification requires gear transmission to effectively control noise at high speeds. This poses a challenge to traditional automotive gear companies. Li Shengqi, secretary-general of the China Automotive Automatic Transmission Innovation Union, pointed out: "Although the number of gears for electric vehicles has decreased, high-speed, high-precision, low-noise gear applications and automatic and lightweight development of transmission assemblies have promoted the technological content of automotive gear products. The added value will increase.Before significant advances in battery technology, traditional fuel vehicles, hybrid vehicles and pure electric vehicles will coexist, and the automotive gear industry will present a trend toward a reduction in the number of gears. In this sense, the automotive gear market Will not shrink."

In Japan, the gear industry is very developed. Gear technology is not advanced technology but mature technology. There are no new problems and new technologies. Students cannot write gear technical papers. Therefore, Japanese universities and colleges do not offer professional courses on gears. At the same time, the Japanese government is not willing to allocate funds to assist the gear industry. Does this mean that the automobile gear industry will disappear in Japan?

“The Japanese automobile gear industry will continue to develop.” The chairman of the Japan Gear Industry Conference and the former Chairman of the Japan Gear Industry Association, Yoshioka Yoshioka, denied that the automobile gear industry will disappear in Japan.

Yoshioka's second work introduced: "With Japan's universities and colleges not offering gear courses and the Japanese government's refusal to assist the gear industry, Japan's historical responsibility for personnel training in gears and gear technology inherited from the industry association. The Gear Industry Association assumed this responsibility and set up the Gear Academy, which is equivalent to a university, employs first-class university teachers, and gears experts who have achievements in the company, and rotates classes in Tokyo, Nagoya, and Osaka to try to get participants to the nearest class. , reduce travel fatigue and benefit gear companies."

When Suzuki Yoshi told a gear class in Japan, he always dedicate the words to young engineers: “Finding things that are based on the principles of principle and implementing them in accordance with your own beliefs; not forcing others to do something, but for people to do things with heart and mind. Thoroughly implement the principles of the scene, present things, and reality, and look directly at the nature of things. Always keep in mind the principles and principles! At present, there are many schools in China that are driving gear. Jigang Gongji believes that China's gear industry will also become very mature.

Chinese vehicle companies often require gear enterprises to process according to the given drawings. There are also many companies like Japan. Yoshioka Yoshioka said: "The gears produced in this way are cheap and of good quality. However, in accordance with the requirements of vehicle companies, gear companies are in a weak and passive position, and there are risks in operating the companies."

"Whole vehicle companies should coordinate and cooperate with gear companies to solve problems." Suzuki Yoshihide advocated the automotive industry to explore new issues related to gears.

Talking about the livelihood issues of gear companies, Suzuki Sayuki said: “The Japanese gear industry had many companies that year, and after the market competition, some companies were merged or closed down, and some companies grew. The Chinese gear industry now also has many companies, after fierce competition. In the market competition, some companies will also be merged or closed down, and some companies will grow stronger."

“The industrial revolution brought about by the new round of scientific and technological revolutions, the use of subversive battery technology, wheel hub motors and high-efficiency and lightweight on-board charging systems will inevitably cause revolutionary disruptions in the traditional automotive gear industry and even the gear transmission industry.” Li Shengqi called on the industry to attach great importance to it.
