Loader stabilizing module, hydraulic system and loader
The invention discloses a loader stabilizing module, a hydraulic system and a loader. A main valve element comprises a first oil port used for being connected with an oil source, a second oil port connected with a rodless cavity of a movable arm oil cylinder, a third oil port connected with a rod cavity of the movable arm oil cylinder, a fourth oil port connected with an energy accumulator and a fifth oil port connected with an oil return port T; the pressure balance valve core comprises a second oil port connected with the energy accumulator and a first oil port connected with the oil return port T; a first control end of the pressure balance valve core is connected with a second oil port of the main valve; the electromagnetic reversing valve comprises a first oil port used for being connected with the energy accumulator, a second oil port connected with the oil return port T and a third oil port connected with the second control end of the main valve element and the second control end of the pressure balance valve element. And the electromagnetic directional valve is used for controlling the connection state between the energy accumulator and the oil return port T, so that the pressure between the rodless cavity of the boom cylinder and the energy accumulator is balanced. The pressure between the rodless cavity oil way and the energy accumulator is balanced according to the pressure change of the rodless cavity of the hydraulic system, sudden shaking of an execution part caused by inconsistency of the pressure between the rodless cavity and the energy accumulator at the moment when the stabilizing module is started is avoided, and the driving comfort and the working efficiency of the whole machine are improved.
本发明公开一种装载机稳定模块、液压系统及装载机，主阀芯包括用于连接油源的第一油口、连接动臂油缸无杆腔的第二油口、连接动臂油缸有杆腔的第三油口、连接蓄能器的第四油口和连接回油口T的第五油口；压力平衡阀芯包括用于连接蓄能器的第二油口、连接回油口T的第一油口；压力平衡阀芯的第一控制端与主阀第二油口连接；电磁换向阀包括用于连接蓄能器的第一油口、连接回油口T的第二油口、连接主阀芯的第二控制端与压力平衡阀芯的第二控制端的第三油口；电磁换向阀用于控制蓄能器与回油口T之间的连接状态，从而平衡动臂油缸无杆腔与蓄能器之间的压力。本发明根据液压系统无杆腔的压力变化平衡无杆腔油路和蓄能器之间的压力，避免稳定模块开启瞬间，无杆腔压力与蓄能器之间的压力不一致，导致的执行件突然抖动，提高驾驶舒适性以及整机工作效率。
