Loader hydraulic system and loader
The invention discloses a loader hydraulic system and a loader in the technical field of loaders, a variable pump inputs hydraulic oil into a steering hydraulic cylinder through a priority valve and a steering gear, and the hydraulic oil is used for controlling the loader to steer; the variable pump inputs hydraulic oil into the first execution element and the second execution element through the priority valve and the energy-saving multi-way valve and is used for controlling the first execution element and the second execution element to complete single action or composite action. An LS2 port of the energy-saving multi-way valve is connected with an LS3 port of the priority valve and used for controlling the steering hydraulic cylinder, the first execution element and the second execution element to complete single action or composite action; the combined combined action of steering, movable arm and tipping bucket of the loader can be realized, the variable effect of the variable pump is fully exerted, and energy conservation is realized.
本发明公开了装载机技术领域的一种装载机液压系统及装载机，本发明变量泵通过优先阀、转向器将液压油输入转向液压缸，用于控制装载机转向；变量泵通过优先阀、节能多路阀将液压油输入第一执行元件和第二执行元件，用于控制第一执行元件、第二执行元件完成单一动作或复合动作；所述节能多路阀的LS2口与所述优先阀的LS3口连接，用于控制转向液压缸、第一执行元件、第二执行元件完成单一动作或复合动作；能够实现装载机转向、动臂、翻斗的联合组合复合动作，充分发挥变量泵的变量效果，实现节能。
