Calculation of Guide Wheel Offset of Front Wheel Guide Tractor

前轮导向拖拉机转向系统的设计,导向轮原地转向阻力矩的计算是前提,行业推荐的计算导向轮阻力矩的方法中尤为重要的一步就是对导向轮偏距的计算。根据几何三角关系建立计算导向轮偏距的数学几何模型,并对拖拉机设计手册中给出的计算公式进行了推导分析,同时也给出了第2种计算导向轮偏距的计算公式,并进行了计算过程的推导。

In the design process of the front wheel-oriented tractor steering system, the calculation of guide wheel＇s in-situ steering resistance moment is precondition. The industry-recommended method for calculating the guided resistance torque is an especially important step in calculating the guide wheel offset. Based on the geometric relationship,a mathematical geometric model of guide wheel offset is established, and the calculation formula given in the tractor design manual is deduced and analyzed. At the same time, the second formula for calculating the guide wheel offset is obtained, and the calculation process is deduced.
