摘要
基于阿克曼原理,详细分析了双导杆转向传动机构的结构特性和运动特性;从理论上证明了该机构能够保证轿车两侧车轮不在同一轴线(由于路况原因)情况下,仍然能够满足纯滚动理论要求,从而达到减小汽车轮胎磨损的目的;在此基础上,对转向横拉杆的平移距离d与汽车转向角α(β)之间的关系和关键参数e的取值方法进行了分析和探讨;结果表明,双导杆转向传动机构可以实现比传统转向机构更小的转弯半径,而且设计简单.
Based on Ackerman principle, the characteristic of structure and movement of double guide rod steering actuator is analyzed in detail. In theory, It is proved that the actuator makes declination of two sided wheels fully satisfy requirement of complete rolling theoretically even if two-sided wheels of saloon car are not in the same axis. And therefore,it can greatly reduce abrasion of saloon car tyre. The paper also analyzes the relation of moving distance of across tie bard and automotive steering angle α（β）, and discusses how to select key parameter e. As a result,it is shown that the sectional double guide rod steering actuator could get smaller turning radius compared with traditional steering system but the design is easier.
