Based on the plan of all-wheel steering system for three-axle vehicles, the corresponding steering linkage mecha-nism is designed, the mathematic model ofthe mechanism is established, and design and calculation are also carried out by u-sing the nonlinear optimization command in MATLAB.The result shows that the mechanism′s steering curve can well fit the theoretical Ackermann curve, and the error between the wheels′theoretical and practical steering angles is relatively small, thus presenting a high precision.In addition, this mechanism can well cooperate with the hydraulic steering system and thus can help to realize the real-time accuracy control of wheels′steering angle.
