Abstract:
According to the tires' serious wear phenomenon and running deviation of a four axle heavy vehicle with double front axle steering mechanism reported by one enterprise,a mathematical model of vehicle's steering and suspension system was established,the motion interference between suspension and steering system was researched, and then the double swing arm's movement rules was analyzed.Finally,this paper took an optimization design of the incompatibility of the movement between suspension and steering linkage,and the trend of tires' non-pure rolling, to reduce the tires' wear and improve the moving compatibility between suspension and steering system,making the road performance of this vehicle much better than before.
Key words: double front axle steering, interference, double swing arm, optimization design
摘要:
针对企业反映的某四轴重型车双前桥转向时出现的轮胎严重磨损和跑偏现象,通过建立该车的转向和悬架系统数学模型,对悬架与转向杆系的运动干涉计算方法进行了研究,并分析了双摇臂机构的运动规律。对悬架与转向杆系运动不协调量,以及轮胎做非纯滚动的趋势进行了优化设计,从而减小了轮胎磨损量,改善了悬架和转向杆系的运动干涉,使车辆的行驶性能更加优越。
