摘要:为提高多轴车辆转向助力系统的性能,以转向系统中转向连杆为研究对象,分别设计了两种助力油缸布置方案,使用ADAMS分别建立了两种方案下转向连杆系统的动力学模型,模型包括转向梯形连杆、转向器连杆和桥间转向机构连杆,通过仿真得到了两种方案中所有杆件在原地转向过程中,由助力油缸驱动克服转向阻力时所受的拉力或压力,分析了各个拉杆在整个转向过程中的受力变化。结果表明:随着转向角度的增大,转向杆系受力普遍增加,其中桥间转向机构连杆受力最大;在两种油缸布置方案中,三油缸布置方案能够使得杆系受力均匀,减少桥间转向杆的受力。

Abstract:In order to optimize the performance of power steering system of multi axle vehicle, this paper took the steering linkage of steering system as the research object, designed two cylinder power layout scheme and established dynamics model of the steering linkage of two scheme by ADAMS. The forces acting on the steering bar which driven by the power cylinder to overcome the steering resistance of the two schemes were obtained by simulation, and the force changes of the tie bars in the whole steering process were analyzed. The results show that with the increase of the steering angle, steering linkage force is generally increased and the bridge between the connecting rod steering mechanisms of had the maximum force. In the two cylinder layout, three cylinder layout scheme can make the rod force uniform and reduce the force of steering linkage between bridge.
