The moving system of milling machine is generally four-wheel independent hydraulic driving. The damage extent of the roads, the hardness of the road, the depth of the milling and the condition of the tools will have an impact on the moving hydraulic driving system.In order to increase the operation performance and reliability of milling machine, ensure the milling machine with higher productivity, operation quality and economic benefit, increase the performance of milling machine, the moving system of 2-meter milling machine have been discussed and designed in this paper.On the basis of analyzing the performance requirements of the 2-meter milling machine and moving system conditions, the overall parameters of the 2-meter milling machine have been determined; kinematics and dynamics analysis of the track milling machine have been done; power analysis of the moving system and milling rotor system have been done. According to the rules of kinematics, dynamics of 2-meter tracked milling machine and the requirements of milling machine moving system, the hydraulic moving system and automatic power distribution control programme which meet the operating characteristics of the milling machine have been designed; the main control programme of hydraulic system and the match parameters between hydraulic moving system and engine have been determined.Keywords：track milling machine，moving system，hydraulic system，de
