Hydraulic bulldozer and walking control system thereof
The invention discloses a hydraulic bulldozer and a walking control system thereof, and the walking control system comprises a steering control system with a steering clutch and a brake, and a variable-speed control system with a plurality of variable speed clutches, the steering control system comprises a steering brake control valve group (5) used for controlling a steering clutch and a brake and a pilot steering valve group (4) used for hydraulic pilot control of the steering brake control valve group, the variable-speed control system comprises a variable-speed control valve group for controlling a plurality of variable-speed clutches and a pilot variable-speed valve group (6) for hydraulically pilot-controlling the variable-speed control valve group. According to the hydraulic bulldozer, a traditional mechanical control mechanism is replaced with electro-hydraulic control, control over steering and speed changing can be programmed through a controller, operation is intelligent, visual and precise, the remote control function can be added, remote control over far and near distances is achieved, gear display can be achieved through an electric control system, and intelligent extended functions such as neutral gear locking and the like are realized.
本发明公开了一种液力推土机及其行走操控系统，行走操控系统包括具有转向离合器和制动器的转向控制系统以及具有多个变速离合器的变速控制系统，转向控制系统包括用于控制转向离合器和制动器的转向制动控制阀组(5)以及用于液压先导控制转向制动控制阀组的先导转向阀组(4)，变速控制系统包括用于控制多个变速离合器的变速控制阀组以及用于液压先导控制变速控制阀组的先导变速阀组(6)。本发明的液力推土机中，采用了电液控制取代了传统的机械控制机构，转向和变速的控制可用控制器编制程序，操作智能化、可视化、精准化，可增加遥控功能，实现远近距离的遥控控制，还可以从电控系统实现档位显示，空挡档位锁定等智能化扩展功能。
