China's auto transmission industry has made new progress in its industrialization

In the past, in the China Automotive Industry Science and Technology Award, automatic transmission-related technology projects were difficult to achieve outstanding performance. This time, two projects won prizes, which undoubtedly shows that the automatic transmission industry has accumulated to a considerable degree in technological progress. The reporter interviewed Li Shengqi, secretary-general of the China Gear Professional Association. He not only talked to reporters about the progress of the industrialization of auto transmissions, but also briefed reporters on other major technological advances in the gear industry.

Li Shengqi disclosed that as of the end of 2012, China's automobile automatic transmission industrialization has made many new developments. For example, Tianjin Zhongde Transmission Co., Ltd. has accumulatively sold more than 1,700 AMTs and is well-operated on hybrid buses in more than 10 provincial capital cities; Hunan Jiangrong Rongda Vehicle Drives Co., Ltd. has cumulatively produced and sold more than 15,000 CVTs. The company has an annual capacity of 50,000 sets of CVTs and has formed strategic partnerships with a number of self-owned brand vehicle companies; 8AT of Weifang Shengrui Drive Co., Ltd. has completed a 48,000-kilometer endurance test at the Xiangfan Auto Testing Ground, equipped with the Shengrui 8AT. Landwind X5 was successfully launched at the Guangzhou Auto Show; Guangxi Yuchai, Nanjing Green Control and other companies based on the AMT hybrid power transmission system have achieved mass production, breaking the monopoly of foreign companies in the field; joint research and development of Shanghai Jiaotong University and Hangzhou Iveco The dry dual-clutch automatic transmission received the general acceptance of the 863 project organized by the Ministry of Science and Technology.

In addition to its application in the automotive industry, gear technology also plays a crucial role in major national science and technology projects. For example, the docking mechanism developed by Guizhou Qunjian Precision Machinery Co., Ltd. “Group Construction Gears” helped Tiangong No. 1 and Shenzhou No. 9 achieve aerospace rendezvous and docking; China Aviation Industry Corporation Xi’an Automatic Flight Control Research Institute passed “information and industrialization”. "Convergence and integration", using the integration of mechanical, electrical, hydraulic, control, and information technology innovations to achieve the transformation and upgrading of the gear industry.

The "China Gear Industry Alliance", which is composed of a hundred enterprises, is regarded as a major event for the gear industry in 2012. Through anti-fatigue and long-life technologies, it solves the long-standing problems of short life, poor reliability, and heavy structure in the gear industry, with a view to achieving the sustainable and healthy development of the entire industry. This is the result of nearly 100 enterprises in the gear industry. Heartfelt. It is understood that the industrial alliance has become an important technical force for the gear industry to take enterprises as the main body, combine production, learning, research and application, and jointly innovate to overcome common technical difficulties in the industry.

Li Shengqi introduced that after many years of exploration and practice, the gear industry has formed a clear industry concept and industry strategy. He stated that “the goal is to build a strong country with gears, take technology innovation as the main line, and transform and upgrade and integrate the two as the main attack direction, and take the anti-fatigue and long-life gear manufacturing technology and the industrialization of automotive automatic transmission as the breakthrough point, strong national ethic. The responsibility of the times will enable the gear industry to reach the world advanced level by 2020."
