摘　　要：介绍全液压装载机传动系统的结构特点和工作原理,并建立静液压无级变速传动系统的数学模型,从理论上阐述闭式液压回路的变速机理。以全液压装载机车速缓慢且铲掘无力为例进行分析并给出故障排除的一般步骤和方法。理论分析和实践应用均表明:液压回路和离合器摩擦片是全液压装载机传动系统的薄弱环节,在使用过程中需要定期进行维修和保养。Structural characteristics and working principle of transmission system of full hydraulic loader are introduced,mathematical model of hydrostatic continuously variable transmission system is established,and transmission mechanism of closed hydraulic circuit is theoretically expounded.Taking full hydraulic loader with slow speed and weak digging as an example for analysis,general steps and methods of troubleshooting are given.Both theoretical analysis and practical application show that hydraulic circuit and clutch friction plate are weak links of transmission system of full hydraulic loader,which need to be repaired and maintained regularly in use.
