The Research Of Automatic Transmission Used In ZL30G Wheel Loader

Intellectualized automatic transmission is now the trend of the loader power train, which greatly improves the performance, the efficiency of the wheel loader and greatly alleviates the driver's working intensity.The paper is founded on analyzing the working characteristic of the wheel loader. The electronic control automatic transmission is rapidly successfully applied in the automobile so that it is gradually adopted in engineering fields. The development process of electronic control automatic transmission and background of its application are introduced. The main researching contents of automatic transmission and developing trend of automatic transmission are expounded . The basic knowledge of the Controller Area Network and the components of the 30G loader automatic transmission system are introduced. The component of the 30G loader power train including the engine and the converter are expounded. The matching characteristic of the engine and the converter are also at large expounded. The three parameters shift strategy that is based upon analyzing the characteristic traction of the 30G loader is put forward. The shift quality of the automatic transmission is introduced. The method that improves the shift quality of the automatic transmission is amply expounded.In conclusion, the theoretical research and application technology presented in the dissertation improve the performance of the loader. They are valuable for application of automatic technology on the loader.
