On May 20, 2016, the Ministry of Industry and Information Technology's National Key Project "High-Power Construction Machinery Electro-Mechanical-Hydraulic Control Automatic Transmission with Automatic Shift," jointly undertaken by HAGG as the lead entity, along with Jilin University, Zhengzhou Institute of Mechanical Research, and Changlin Co., Ltd., successfully completed full-vehicle prototype operation tests at Changlin Co., Ltd.'s test facility. The next step will involve further optimization based on these trials, followed by comprehensive vehicle-level factory acceptance tests and ultimately handing over the product to relevant users for performance evaluation in real-world applications.
This automatic transmission is an engineering machinery gearbox independently developed by HAGG. It primarily consists of key components such as a hydraulic transmission, an electronic control unit (TCU), a shift lever, and wiring harnesses. The gearbox features essential automatic shifting functions, along with advanced safety, diagnostic, and auxiliary capabilities. The development of the automated shifting system was led by Dr. Xingzhong Li from HAGG as part of his postdoctoral research project. Under the guidance and coordination of Chief Engineer Bin Song, the project leader, team members from the Technical Center worked diligently over more than a year, successfully completing each phase—including project plan validation, critical component development, bench testing, and full-vehicle calibration trials—ultimately achieving the prototype's seamless automatic shifting functionality in a complete vehicle setup.
The successful implementation of this project has propelled the company's development in electro-hydraulic control automation technology, providing robust technical support for the industrialization of related automatic transmission products in fields such as construction machinery and rail vehicles.
