摘要:
PROBLEM TO BE SOLVED: To reduce energy loss, and to improve responsiveness of a steering control system.
SOLUTION: When a steering operating element is quickly operated, opening area of a steering flow control valve 4 is quickly increased to quickly reduce a pressure difference (Pp'-PL) between in front and rear of the steering flow control valve 4. When the pressure difference (Pp'-PL) between in front and rear of the steering flow control valve 4 is quickly reduced, a flow control valve 6 is energized by spring force of a spring 6f to quickly move toward a valve position 6b in order to increase the pressure difference (Pp'-PL) in front and rear to make it coincide with a set pressure. Pressure oil at a flow rate α to spare and flowing in a discharging oil passage 7 till then is quickly supplied from the flow control valve 6 to a steering hydraulic cylinder 5 through the steering flow control valve 4. An output Q' thereby quickly rises in relation to an input St.

要解决的问题:减少能量损失,提高转向控制系统的响应能力。 解决方案:当转向操作元件快速操作时,转向流量控制阀4的开口面积快速增加,以快速减小转向流量控制阀4前后的压力差(Pp'-PL) 当转向流量控制阀4的前后的压力差(Pp'-PL)迅速降低时,流量调节阀6通过弹簧6f的弹簧力被激励,以迅速向阀位6b移动 以增加前后的压力差(Pp'-PL)使其与设定压力一致。 直到那时在排出油路7中备用和流动的流量α的压力油通过转向流量控制阀4从流量控制阀6迅速地供给到转向液压缸5.输出Q'因此迅速上升 与“输入”的关系版权所有(C)2005,JPO&NCIPI
