摘　　要：该文主要介绍了四轮驱动挂装车液压系统的设计原理,简要介绍了挂装车的结构设计。该挂装车采用后轮驱动、四轮转向的方式,其工作装置可以在6个自由度上进行调整,并在驻车制动、工作装置液压系统中设置应急系统,确保挂装车的作业安全。样机的研制成功证明了该挂装车液压系统的设计是合理、适用的。This paper describes the design of the hydraulic system of the loading truck for equipment hanging on aircraft with four wheels steering. And the paper describes the design of the truck＇ s structure. The truck which with rear-wheel-drive and four-wheel-steering has a hanging structure which with 6-freedom. For the safety of the truck during hanging equipment on aircraft, there is an emergency hydraulic- circuit connecting to the parking hydraulic-circuit and the hanging hydraulic- circuit. The success of designing and producing the first truck proves that the design of hydraulic system of the truck is logical and useful.
