驱动式圆盘犁机组的受力分析

以整个机组为对象，对驱动式圆盘犁机组作受力分析．计算了拖拉机前后轮载荷的变动量，机组的直线行驶性能，驱动式圆盘犁在水平面内的平衡，以及工作参数、悬挂参数对水平面内平衡的影响，并以１ＬＹＱ－４２２驱动式圆盘犁机组田间实测数据进行验算．结果表明，拖拉机前后轮载荷变动量及偏转力矩均较小；当耕作速度较大时，圆盘偏角对平衡性能影响较大；水平瞬心π２靠近驱动轮轴及右侧时可提高平衡能力．

Force analysis on power driven disk plow tractor mounting unit

In this paper ,the forces on power driven disk plow tractor mounting unit and the performance of keeping tractor traveling straight were calculated, the formula of load alterations on the tractor′s front and back wheels have been deduced,and the effect of working and linkage parameters on power driven disk plow balance on horizontal were discussed. There was a further calculation using the field test data of 1LYQ 422 power driven disk plow tractor mounting unit.The results showed that the load alterations on the tractor′s front and back wheels were small, and there was a significant effect of disk tilt angle on balance performance. The balance capacity could be improved by π2 near the right side of driving wheels.
