| 摘 要： | 分析了分置式转向助力机构的液压缸活塞杆与转向直拉杆相铰接的球头销的运动特性，建立了其轨迹方程及压力角的数学模型。通过计算机辅助分析，求得了该点压力角的变化规律及给定杆系参数下压力角的最佳变化区间。对FR1608运输车转向助力机构的分析结果表明，在转向器转向垂臂的标准摆动范围内，设计参数满足最佳压力角要求。

| Abstract: | This paper analysed the kinematic properties of ball joint hinged on the piston rod and steering drag link of a separated assistant steering mechanism, and the equations of the path and mathematical model of pressure angle were established. The changing regularity of pressure angle of ball joint and the optimum position region of pressure angle in given rod structure were proved through computer aided analysis. It is indicated through the analysis of assistant steering mechanism of the farm transporter model FR1608 that within the range of standard swinging of the pitman arm, the design rod structure satisfies the requirement of optimum pressure angle. |
