The invention discloses an automatic following steering control hydraulic system of a ladle transport vehicle, which is mounted on the ladle transport vehicle. Comprising a variable displacement piston pump, a front steering control system, a front steering execution element, a front steering following system, a rear steering control system, a rear steering execution element, a rear steering following system, a front wheel position feedback device, a rear wheel position feedback device, a PLC and a remote controller. When a driver rotates a steering wheel in a front cab to conduct front wheel steering, the PLC controls the rear steering following system according to the front wheel steering angle fed back by the front wheel position feedback device, the rear steering oil cylinder and the front steering oil cylinder are made to be synchronous, and the function that the rear wheels automatically and synchronously follow the front wheel to conduct steering is achieved. The device is accurate in neutral position returning, small in synchronization error of the front and rear oil cylinders, good in repeatability and free of oil supplementing.
本发明公开了一种铁水包运输车自动跟随转向控制液压系统,安装于铁水包运输车上,包括变量柱塞泵、前转向控制系统、前转向执行元件、前转向跟随系统、后转向控制系统、后转向执行元件、后转向跟随系统、前轮位置反馈装置、后轮位置反馈装置、PLC控制器和遥控器;当驾驶员在前驾驶室内转动方向盘进行前轮转向时,PLC控制器根据前轮位置反馈装置反馈的前轮转向角度控制后转向跟随系统,使后转向油缸与前转向油缸同步,实现后轮自动同步跟随前轮转向功能。本发明回中位精准,前后油缸同步误差小,重复性好,且无需补油。
