摘 要: | 为了解决传统联合收割机田间转向时对地表的破坏、减少田间频繁转向时对摩擦片的损耗及缩短田头转向时间,设计了一种通过制动差速器齿轮从而使得动力反转的原地转向机构。分析了系统的工作原理,计算校核了核心部件的强度,针对相关转向性能进行了干沙路面动力学仿真。仿真结果显示该机构可实现3种转向模式:在输出动力侧加载线速度相同时,原地转向模式转过90°用时最短、功耗最高、转矩最大;自由转向模式中进行转向微调时无需使用摩擦片;单边制动转向模式能够进行急转向。所建立的路面模型可以为下一步的田间作业模拟奠定基础。

Abstract: | In order to solve the damage of the field surface when the combine harvester steering ,reduce the loss of the friction plate when combine harvester frequently steering in the field , shorten the turnaround time .design a pivot steering transmission which reversal the power by brake differential gear .Analyse the working principle of the system , calculate and check the strength of the core components , in connection with the related steering performance conduct a dynamic simulation .The result show that the mechanism can achieve three types of steering , when the power output side load the same line speed , the pivot steering with the shorst time , the maximum power consumption and the maximum torque ,fine-turn steering don ’ t need to use friction plate , the pavement model can lay the foundation for next field operations simu-lation . |
