Analytical Design on Steering Motion of Wheeled Vehicle

运用矢量和矩阵,确定了在车辆直线和转弯行驶时,导向轮轴和转向节臂的方位。进而导出节臂转角、转向角和外倾角之间关系,以及阿克曼转向中的节臂转角间理想关系等方程式,为各种轮式车辆转向机构的设计和研究提供了良好的基础。

To do a good analytical design for steering motion of wheeled vehicles is not a easy thing,so an excellent analyticalmodel of vehicle steering remain not being developed up to now.By using vector and matrix in this paper,the directions of guiding wheels and steering arms are determined analytically for both the vehicle going straight and making a turn.Several new and important formulas are obtained,such as the relationship among arm's turning angle,steering angle and camber angle,the ideal equations between two arm's turning angles under Ackermann steering.The model and formulas set up here are integral,distinct,succinct and accurate,providing a fine basis for precision design and deepgoing study of steering mechanisms in various wheeled vehicles.
