The invention provides a forklift steering electro-hydraulic control system which comprises a frame and a steering device hinged to the frame, a driving oil cylinder for driving the steering device to rotate extends out of the frame, and the driving oil cylinder is connected to a whole forklift hydraulic system. The controller is used for controlling the extension length of the driving oil cylinder when the steering angle of the steering device is switched; and the controller synchronously controls the whole vehicle hydraulic system to be matched with the reversing speed of the steering device. A steering device is arranged at the front end of a frame, a driving oil cylinder drives the steering device to conduct rotation angle switching action, meanwhile, the driving oil cylinder is connected to a whole vehicle hydraulic system, the extending length of the driving oil cylinder is matched with the reversing speed of the steering device through a controller, and the whole vehicle hydraulic system provides oil for the driving oil cylinder to reach the preset extending length. The accuracy of the steering angle of the steering device is ensured by the extension length of the driving oil cylinder.
本发明提供了一种叉车转向电液控制系统,包括车架和铰接设于车架上的转向装置,车架上还伸出有驱动转向装置回转的驱动油缸,驱动油缸连接至整车液压系统;还包括在转向装置的转向角度切换时,控制驱动油缸的伸出长度的控制器;控制器同步控制整车液压系统与转向装置的换向速度相匹配。车架前端设置转向装置,由驱动油缸驱动转向装置进行转动角度切换动作,同时将驱动油缸连接至整车液压系统,通过控制器将驱动油缸的伸出长度与转向装置的换向速度相匹配,由整车液压系统提供驱动油缸达到预定伸出长度的油量,由驱动油缸的伸出长度确保转向装置转向角度的准确性。
