From August 9 to 11, 2016, the International Symposium on the Industrialization of China's Auto Transmission was held at the Jinmao International Hotel, Weifang, Shandong. In this seminar, Shengrui Drive Co., Ltd. (Sherry) had a good news: Shengrui 8AT (8-speed automatic transmission) will exceed 100,000 units this year and will produce 300,000 units. Annual output enters.
Zhang Zhidong, Executive Director of Zhejiang Wanliyang Co., Ltd., highly praised: “The new progress of Shengrui 8AT industrialization has greatly enhanced the self-confidence in the industrialization of the automatic transmission in the domestic automobile industry!â€
After close discussions with nearly 200 delegates from the auto transmission industry at home and abroad, the seminar revealed that the industrialization of domestic auto transmissions has revealed three major problems while achieving new breakthroughs.
â– Development is Still Weary In the past five years, Shengrui has been firmly convinced and has worked hard to achieve the world's first 8AT batch production.
“We adhere to the market orientation and jointly develop with our customers, foster an autonomous AT (hydraulic automatic transmission) industrial chain, and drive the development of a large number of domestic parts and components companies, laying a solid foundation for domestic AT industry and foreign AT industry to compete.†Sheng Rui Director Liu Xiangwu introduced the 8AT industrialization experience at this seminar.
Zhang Zhidong pointed out: "The demand for China's auto transmission market is in a period of rapid growth, which will be critical in the next few years. We should soberly realize that the gap between the independent innovation capability of China's auto transmission and the developed countries is still very large."
According to Zhang Zhidong, Liu Xiangwu deeply feels that “China’s auto transmissions are still weak in research and development, and their products and technologies are uneven. China’s auto transmissions are still lacking in talents. Compared with developed countries, there are still talents in China’s auto transmissions. A long way to go; talent strategy should arouse great attention from the state. China's auto transmission development is dispersive and wasteful."
"These weak links should be the guideline for our actions. The industrialization of automobile automatic transmissions requires the integration of resources, and it is necessary to break through the catastrophes of their own actions and scattered forces." Liu Xiangwu advocated the development of the automobile automatic transmission industry.
In the next five years, Shengrui will complete the development and application of high-end automatic transmissions for the three platforms of traditional power vehicles, energy-saving vehicles and new energy vehicles, and build the first domestic automobile automatic transmission supporting industrial park and logistics park to create an international influence. Automotive automatic transmission research and development and manufacturing base.
Zhang Zhidong said: “Shengrui’s experience deserves attention. We must make full use of resources and experience in all aspects, make great efforts, work hard, and strive for excellence.â€
â– quality parts drag <br> <br> the seminar raised a very important issue, that is dragged domestic auto parts quality automatic transmission industrialization hind legs.
Zhang Zhidong said: "The quality of auto parts in China's auto transmission industry is far inferior to that of developed countries."
“Some parts and components needed for the industrialization of domestic auto transmissions are still dependent on imports.†Liu Xiangwu has deep feelings about Zhang Zhidong’s situation.
Fortunately, some domestic parts and components companies are striving to develop and produce qualified parts and components for the industrialization of automotive automatic transmissions.
Automotive automatic transmissions must have high-end seals. In the past, high-end seals used in domestic automotive automatic transmissions had been dependent on imports.
Yan Xubing, deputy general manager of Yantai Runfuxiang Oil Seal Co., Ltd. (abbreviated as Yantai Runxiangxiang), said in an interview with reporters: “The domestic parts and components technologies and products have not kept pace with the industrialization of automobile automatic transmissions and have restricted the industrialization of domestic automobile automatic transmissions. We are willing to contribute to changing this backward situation.We have spent 7 years working hard to tackle the problem and have now mastered the advanced sealing technology for automotive automatic transmissions. Currently, we have invested in high-end seals developed for Geely 6AT. During the test phase, high-end seals are being developed for the Shengrui 8AT and Japanese Aisin automatic transmissions."
The poor quality stability of large-volume supply is the biggest obstacle to the development of China's auto transmission industry. Dong Xubin said: "We will use three to five years to resolve the problem of the unstable quality of the high-end seals in automotive automatic transmissions."
To ensure the quality stability of auto transmission components, automatic production equipment is required. Yantai Runqixiang has purchased six advanced machines and two automatic production lines from Germany.
Dong Xubing said: “We will use automated production lines to ensure the consistency of product quality for mass production and reduce the gap between the quality stability of high-end seals for automotive automatic transmissions in China and developed countries. In the next three years, automation will become our business. Mainstream production."
Because the self-developed automotive automatic transmissions in China have not been able to support vehicles in batches, many domestic parts and components companies have been developing auto transmission accessories for many years and have not received market returns, no profit, and have been losing money. Dong Xubing did not feel pessimistic about this. He said: "The automobile automatic transmission industry is a sunrise industry. It is worthwhile to invest in this sunrise industry. Once the domestic automobile automatic transmission develops greatly, we can keep up and we will not be left behind!"
â– New energy power transmission assembly still needs improvement
“At present, there are four major problems with domestic new energy vehicle power transmission assembly products. One is the issue of the rationality of the matching between motors and automatic transmissions and speed reducers. The other is that the motor EMT (Electrically Controlled Mechanical Automatic Transmission upgraded version) faces The third problem is the reliability. The fourth problem is the change from singleness to diversity in the new energy auto transmission products.†These questions raised by Prof. Cheng Xiusheng of the College of Automotive Engineering of Jilin University drew the attention of many participants.
The rapid development of electric vehicles. Li Shengqi, secretary-general of the China Automotive Automatic Transmission Innovation Union, pointed out: “The automatic transmission and motor are optimized to match and highly integrated a highly efficient lightweight new powertrain, which is a rare common market opportunity for the Chinese automotive gear industry and the electric motor industry. However, the domestic industry The new electric powertrain has not been studied in depth. Shengrui has built a successful road for the domestic automotive automatic transmission industry in the field of innovation, development, cooperation, and innovation.
Multidisciplinary integration and cross-industry collaborative innovation are the fundamental driving forces for the transformation and upgrading of the automotive gear industry. The Chinese gear industry is undergoing a difficult transition. Li Shengqi said: "At this time, we advocate and expect the whole industry to jointly create the industry culture in the new period and the new situation, carry forward the achievements of others and also achieve their own spirit of cooperation and continuous innovation."
