装载机多路阀气动操纵系统设计

Design of Aerodynamic Operating System of Loader Multiple Valve

论述了装载机现行的操纵机构,对液压先导操纵阀的应用局限性进行了分析。介绍了气动助力器的工作原理,通过对操纵手柄上的期望力的分析计算获得满足性能要求的操纵力。装载机操纵机构借助助力器的助力作用,可以用较小的操纵力对装载机进行轻松操纵,从而使操作轻便灵活。

This paper introduced the current operating system of loader, analyzed the application limitation of hydraulic pilot control valve, introduced the working principle of aerodynamic booster. Through calculation and analysis, we got the expected force which acted on the operating handle. With the force of the aerodynamic booster, we can manipulate the loader relaxedly with less force, and control it conveniently and easily.
