摘　　要：根据某高速轮式工程机械高原使用时热平衡系统出现的过热问题,分析了过热问题产生的原因,改进设计了热平衡系统,采用分离油水散热,冷却水、变矩器油、液压油使用各自的散热器,散热风扇采用液压马达驱动,控制器根据系统温度状态自动控制风扇转速等方法,经仿真分析及实车试验,解决了机械热平衡系统高原使用的过热问题,实现了平原、高原地区兼顾使用,拓展了装备的环境适应性及应用范围。According to the overheating problems of thermal equilibrium system for a high-speed wheeled engineering machinery in plateau, the causes of overheating problems is analyzed and the design of thermal equilibrium system is improved. Through the use of separate water and oil cooling, cooling water and torque converter oil and hydraulic oil using the respective radiator, cooling fan is driven by a hydraulic motor , fan speed is automatically controlled according to the system temperature. The simulation analysis and real vehicle test are carried out, the overheating problems of thermal equilibrium system in plateau are resolved, The machinery can be used in plateau and plain, and can expand the equipment environmental adaptability and application scope.
