The Ministry of Science and Technology recently accepted and accepted the National 863 Project “Technology Development for Heavy-Duty Commercial Vehicle Automatic Transmission†led by China National Heavy Duty Truck Group Datong Gear Co., Ltd. in Wuhan. The acceptance expert group unanimously held that the scientific research achievements completed in the implementation of the project and the technical performance indicators of the prototype all reached relevant technical standards.
With the continuous development of science and technology and the intensification of the lack of international energy, energy saving and environmental protection have become new competition points in the domestic and foreign automotive industry. At present, the configuration of the AMT automatic transmission in the European and American heavy-duty commercial vehicle market has realized industrialization. AMT automatic transmission simplifies the driver's operation, improves driving safety, reduces fuel consumption, reduces pollutant emissions, and increases user economic benefits. Many enterprises and related institutions in China are still at the prototype development stage so far, failing to grasp the core technology of AMT.
AMT automatic transmission is based on the MT manual transmission, automatic shifting through integrated shift control system and electronic control unit. It not only maintains the high transmission efficiency of MT manual transmission, but also has a good production inheritance, and is suitable for China's national conditions. The market prospect is very broad. The research and development of the AMT automatic transmission project is of great significance to advancing the technological advancement of China's heavy-duty commercial vehicles, enhancing the competitiveness of China's heavy-duty commercial vehicles in the international automotive market, and promoting the building of a harmonious society in China. Therefore, it is imperative to accelerate the independent innovation and industrialization of the complete set of technologies for China's "automobile transmission assembly."
In January 2007, the Ministry of Science and Technology formally approved the implementation of the research and development of the project of "the development of heavy-duty commercial vehicle automatic transmission technology." Big Tooth Company specially established an AMT project research and development team to complete the AMT automatic transmission prototype design, detailed design, prototype prototype, prototype bench test, sample loading road test and product prototype calibration.
In the course of project R&D, Dazuo Company established the AMT automatic transmission comprehensive performance test platform; completed 19 AMT automatic transmission enterprise standards; published 9 papers, including 4 EIs; obtained 1 patent after the completion of the project There are 4 patents accepted and 5 patents are being filed.
