The invention discloses a steering control device and method for a three-fulcrum multi-directional driving forklift. Steering wheel and main controller, an absolute value encoder is arranged in the steering wheel; the absolute value encoder is used for collecting a rotation signal of a steering wheel; the absolute value encoder controls the steering angle of one steering wheel through the main controller according to the mode switching switch; the steering angles of the other two steering wheels are regulated and controlled through an algorithm executed by the main controller according to thesteering angles of the steering wheels controlled by the absolute value encoder; the mode switching switch controls the walking modes of the whole vehicle, and the walking modes comprise the straight-going large-radius steering mode, the straight-going small-radius steering mode, the side-going steering mode, the diagonal steering mode and the pivot rotation mode. Multiple steering modes are set,the steering angles of the left front wheel, the right front wheel and the rear driving wheel can be adjusted in a linkage mode in different modes, operation steps are simplified, abrasion of the steering wheels is reduced, and working safety is guaranteed.

    本发明公开了一种三支点多向行驶叉车的转向控制装置和方法,包括方向盘和主控制器,所述方向盘内设置有绝对值编码器,所述绝对值编码器用于收集方向盘的转动信号,所述绝对值编码器根据模式切换开关通过主控制器控制一个转向轮的转向角度,另外两个转向轮的转向角度通过主控制器执行的算法根据绝对值编码器所控制的转向轮的转向角度调控,所述模式切换开关控制整车的行走模式,包括直行大半径转向模式、直行小半径转向模式、侧行转向模式、对角转向模式和原地回转模式;本发明设置了多种转向模式,左前轮、右前轮和后驱动轮的转向角度能够在不同模式下进行联动调整,简化了操作步骤,减小了转向轮磨损,保证了工作的安全性。
