The invention discloses a two-way cushion valve, a loader steering system and method and a loader, the two-way cushion valve comprises a valve block body, and a left overflow valve, a right overflow valve, a control valve, a left one-way valve, a right one-way valve, a left damper and a right damper which are connected with the valve block body, and the valve block body is further provided with an L oil port and an R oil port; the oil port L is respectively communicated with an inlet of the left overflow valve and an outlet of the left one-way valve, and is communicated with a left control end of the control valve through the left damper; the oil port R is respectively communicated with an inlet of the right overflow valve and an outlet of the right one-way valve, and is communicated with the right control end of the control valve through the right damper; an outlet of the left overflow valve and an outlet of the right overflow valve converge and then enter the control valve. An outlet of the control valve is connected with an inlet of the left one-way valve and an inlet of the right one-way valve. The steering impact of the steering system of the loader can be effectively reduced, and the steering stability of the loader is improved.

    本发明公开了一种双向缓冲阀、装载机转向系统、方法及装载机,双向缓冲阀包括:阀块体及与所述阀块体连接的左溢流阀、右溢流阀、控制阀、左单向阀、右单向阀、左阻尼和右阻尼,所述阀块体上还设置有L油口和R油口;L油口分别与左溢流阀的入口、左单向阀的出口连通,同时通过左阻尼与控制阀的左控制端连通;R油口分别与右溢流阀的入口、右单向阀的出口连通,同时通过右阻尼与控制阀的右控制端连通;左溢流阀的出口、右溢流阀的出口合流后进入控制阀,控制阀的出口分别连接左单向阀的入口和右单向阀的入口。本发明可以有效降低装载机转向系统的转向冲击,提高装载机的转向稳定性。
