Firstly, this paper discusses the development actuality of the research on double-front axle steering system and power-train of automobile. Based on the structure of the design experiences from others, the kinematics formula of double-front axle steering system is fetched, and the mathematical model of optimization design of double rocking arms mechanism and steering trapezium mechanism is established by space geometry method. Considering the difference between the real steering angle from wheels and the ideal steering angle from the ideal formula as the objective function, the optimization design method of double-front axle steering system is presented.
