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。

摘  要:
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 simulation.
