| Abstract: | The domestic and overseas status and the shortage of electro-controlled gear shift of construction machinery were analyzed. The model for electro-hydraulics proportional gearshift with clutches control system used in the construction vehicles was developed. Based on analyzing the type and the development of shift strategy, the fuzzy shift strategy is presented. In order to examine the simulation modes and fuzzy shift strategy, the vehicle speed and the shift were simulated under typical driving conditions. A new way was presented for solving the electro-controlling problems of planet gearbox clutches of large and middle power construction machinery in our country. |
