四轮底盘转向方式对工作行程率影响的研究

摘要

In order to achieve small turning radius and improve the working stroke rate of four-wheel chassis , agricultural machinery can improve the operational efficiency .The four-wheel tractor operating in small plot turning radius and field width can influence the blank line time .In order to improve small plots of blank line time , the key to come to the chassis with a small turning radius , and can not require reversing steering directly into the next furrow forms .The author believes front axle swing steering-wheel-drive chassis is more suitable way of small plots operations .In the steering , The chassis control the rotation of the front axle drive wheels , the front axle steering device rotates around the initiative , drive chassis to any angle turning .Through compared the front axle swing steering working stroke rate with deflection chassis ’ , the front axle swing steering chassis enhance the work small plots stroke rate .%实现四轮底盘小半径转弯，提高小地块工作行程率可提高农业机械的作业效率。通过对现有的四轮拖拉机在小地块作业时转弯半径、地头宽度对空行时间的影响分析，得出提高小地块空行时间的关键是底盘要具有转弯半径小、不需要倒车便可直接驶入下一畦的转向形式。作者认为前桥摆转转向方式四驱底盘更加适合小地块作业。该底盘在转向时，通过控制前桥驱动轮的转动，使前桥主动围绕着前桥中心点的转向装置转动，带动底盘以任意角度转向。通过将前桥摆转转向式底盘的工作行程率与偏转式底盘相比较，证明前桥摆转转向底盘更能提高小地块工作行程率。
