摘要
基于国内多数车辆为定轮距或轮距人工有级可调,不能实现灵活调节轮距的现状,提出一种将底盘车桥交叉布置,通过改变车桥夹角来无级调节轮距的方法.介绍了交叉变轮距车辆底盘结构,分析了车辆轮距调整和转向原理,借助MATLAB对转向机构进行优化设计,并且分析了交叉变轮距车辆的转向误差.结果表明,转向机构优化后的交叉变轮距车辆转向时产生的误差在允许范围内,能够使转向更加接近理想状态,对交叉变轮距车辆的研究具有一定的参考价值.
Due that the wheel-track most domestic vehicles are fixed or artificially-adjustable,not flexible to adjust wheel-track,a method is proposed across the chassis axle to change the axle angle to adjust wheel-track.Firstly,the chassis structure of crossing variable wheel-track vehicle is analyzed on wheel track adjustment and steering.By using MatlabTM for optimal design on steering mechanism,the steering error is then obtained.Finally,it is indicated that the errors are within the allowable range,whereas the steering approaches the ideal state.
