A hydraulic system for a crawler travelling apparatus includes: a pair of crawler drive subsystems; an action element driving subsystem; the control handle is used for inputting an action instruction of the action element; a main pump; controlling an oil source; and a controller. Each track driving subsystem comprises a track motor; a crawler main valve for controlling the main pump to supply hydraulic oil to the crawler motor; the hydraulic control pedal is configured to receive the control oil from the control oil source and output pilot pressure to the track main valve. The hydraulic system further comprises a pressure sensor for detecting pilot pressure output by the hydraulic control pedals and a pressure regulating valve arranged between the control oil source and the input ports of the two hydraulic control pedals. And the controller controls the pressure regulating valve based on an action instruction of the action element input by the control handle so as to regulate the pressure of control oil supplied to the hydraulic control pedal by the control oil source.
一种用于履带行走式设备的液压系统包括:一对履带驱动子系统;动作元件驱动子系统;用于输入动作元件的动作指令的操控手柄;主泵;控制油源;以及控制器。每个履带驱动子系统分别包括:履带马达;履带主阀,其控制主泵向履带马达供应工作油;液控脚踏,其配置成接收来自控制油源的控制油并且向履带主阀输出先导压力。液压系统还包括检测液控脚踏输出的先导压力的压力传感器,以及布置在控制油源与两个液控脚踏的输入端口之间的压力调节阀。控制器基于经操控手柄输入的动作元件的动作指令控制压力调节阀,以调节控制油源向液控脚踏供应的控制油的压力。
