“Prioritizing the development of AMT and CVT, timely development of DCT, and proper production of AT.†This was one of the key points of the industry development plan proposed by China Gear Professional Association five years ago, but it did not attract the attention of the automotive industry at that time. Because the gap between China's auto transmission industry and foreign countries is obvious, whether it can catch up with the advanced level of developed countries is not to shout a slogan to solve the problem. Five years later, what are the developments of these four automatic transmissions? Four kinds of domestic automatic transmissions have formed the basis of industrialization The reporter learned from the China Gear Professional Association that after the development in recent years, the domestic autonomous transmission plant has gradually transformed the above-mentioned programmatic plans into reality, and four types of automatic transmissions such as AMT, CVT, DCT, and AT have been Domestically formed different degrees of industrialization basis. In the AMT field, Nanjing Afu Automotive Control System Co., Ltd., with AMT products with a 0.6-1.3-liter engine, has been applied in batches on certain models such as Great Wall, Changhe Suzuki and Zhongtai; AMT products of Chongqing Qingshan Industry Co., Ltd. have been in small batches. The Dongyue MPV model will be put into production within one year. In the field of commercial vehicles, several manufacturers of AMT products based on city buses have entered the trial phase, especially for hybrid buses AMT products, and they have been able to ensure the controllability and comprehensive fuel economy of buses. The role of large; multi-range AMT products for heavy trucks have also been successfully developed by Fast and other manufacturers. The safety and convenience of driving has been fully demonstrated during the trial process. In the field of CVT, autonomous CVT manufacturers, mainly Jiangrong Rongda Vehicle Transmission Co., Ltd., have already achieved industrialization of small-batch production in domestic Lifan and Zhongtai vehicles, and installed more than 1,000 vehicles per month. Others, such as Beijing Videdi Automotive Technology Co., Ltd.'s Activech CVT technology, also study the driving comfort and energy-saving effects from different perspectives. If the industrialization is successful, it will have a great impact on the entire automotive industry. In the field of DCT, Chongqing Qingshan, Geely Automobile, Jianghuai Automobile, Hangzhou Iveco and other companies have gradually industrialized the world’s most technologically advanced automatic transmission products, and will break the automatic transmission subdivision monopolized by European companies. Market pattern. In the AT field, Weifang Shengrui Drive Co., Ltd. has used international resources and introduced German technology, although it has long believed that AT products are the most mature technology in automatic transmissions, foreign patent monopoly is the most serious, and domestic industrialization is the most difficult branch. The independently developed 8AT product adopts a four-degree-of-freedom planetary transmission mechanism and five shifting elements arranged in two shafting arrangements to solve the problem of compact layout and convenient shifting. The product can also be extended to 7th and 6th gears. And 5 block. The development of Shengrui broke through the blockade of foreign patents, and the research and development team led by Beijing Airlines also broke the conventional model of domestic companies’ R&D as the main body. Assembly Innovation Alliance R&D Common Technology In the process of developing autonomous brand automatic transmissions, domestic related companies are first faced with common technical problems. To this end, at the end of 2009, with the initiative of the China Gear Professional Association and the China Automotive Engineering Society, more than 30 related key enterprises, universities, research institutes and other units spontaneously organized the establishment of an automotive automatic transmission assembly innovation alliance. Its purpose is to jointly research and develop common technologies to form the independent innovation capability of China's energy-saving transmission assembly, break through foreign technology blockade, and form an autonomous automatic transmission assembly industry. The reporter noticed that, unlike some industrial alliances, the goal set by the Autotransmission Consortium has emphasized the “assemblyâ€. In other words, it emphasizes the link between the industry chain of related companies and the final supporting and application of products. Moreover, in the long run, the goal of the alliance members is not to make efforts for large multinational corporations to earn money. It is devoted to the real industrialization of China's autonomous automatic transmission products. Li Shengqi, secretary-general of the China Gear Professional Association, disclosed to reporters that since large foreign companies usually use forward design methods, our companies are in a wide range of design methods, test and detection technologies, software and hardware equipment and technical databases, and foreign advanced level gaps. Larger, making the current domestic independent enterprise research and development to "make up" in many ways. The main role of the alliance and the association is to form a lead in common technologies and reach consensus with members to jointly undertake the development of core technologies and key components. According to reports, the R&D and reliability of key components and core components, and the matching, calibration, and optimization of complete vehicles and engines in the several technologies being developed by the China Gear Professional Association and its members, are all around the electronic control system. Hardware and software R&D, etc., are the top priorities in the process of industrialization of automatic transmissions. In the “Guidance Catalogue for Industrial Structure Adjustment (2011 Edition)†recently released by the National Development and Reform Commission, there are DCTs and AMTs in the encouraged industrial projects; AT products with 4 speeds and below are mentioned in the eliminated and restricted industrial projects. . Li Shengqi expressed his support for this. He believes that the diversification of the development of China's automatic transmissions will not be wrong. However, today, energy conservation has become a national strategy, and 4AT products will certainly be eliminated. Therefore, he expressed concern that some manufacturers are still preparing to introduce 4AT technology. It is worth noting that the industry’s concern is that compared with the situation in the past few years when R&D was conducted by several independent transmission manufacturers in China, “it is now awake for the entire vehicle company.†Li Shengqi told reporters, “The reality has once again proved that the market can not change. To come to technology, domestic independent auto companies and transmission-related companies are the only way to promote the industrial process."
