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 pefformance 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 cold recycling milling machine have been diseussed and designed in this paper. On the basis of analyzing the performance requirements of the cold recycling milling machine and moving system conditions， the overall parameters of the cold recycling milling machine have been determined ; kinematics and dynamics analysis of the rack milling machine have been done ; Power analysis of the moving system and milling rotor system have been done.Aecording to the rules of kinematies， dynamics of cold recycling tracked milling machine and the requirements of milling machine moving system，the hydraulic moving system and automatic power distribution control programme which
