井下装载机由于工作环境及工作条件的限制，要求其行车时必须制动可靠，这就对井下装载机的液压制动系统提出了更高的要求。本文对WJD／WJ－2型电动、内燃井下装载机液压制动系统使用中出现的问题进行分析，在消化吸收国外技术的基础上，选用国产液压元件，设计出～套新型液压
Due to the limitation of working environment and working conditions, the downhole loader requires that its driving must be braked reliably, which puts forward higher requirements on the hydraulic braking system of the downhole loader. This paper analyzes the problems in the use of WJD / WJ-2 electric and internal combustion well under hydraulic brake system. Based on the digestion and absorption of foreign technologies, the domestic hydraulic components are selected to design a new set of hydraulic
