摘　　要：利用运动学原理分析偏转车轮的转向规律,得出运动参数表达式。简要介绍三种偏转车轮转向方式的特点,重点介绍铰接转向的概念及特点,举例分析铰接式液压动力转向机构。针对铰接式车架的特点,利用运动学和数学理论,对铰接转向机构的运动学规律进行详细论述和推导,得出相应的表达式,指出铰接转向机构的不足。SThe kinematic theory is used to analyze how deflecting wheels steer in order to establish the kinematic parameter expressions.The paper briefs the features of three steering modes made by deflecting wheels and focuses on the concept and characteristics of articulated steering system and takes examples to study an articulated hydraulic steering linkage.Based on the structure of articulated frames,the paper uses the kinematics and mathematical theories to study and deduces the motion of articulated steering system and establish the expression and also points out the drawbacks.
