摘要
基于多体动力学理论,建立了驱动桥系统分析模型。在综合考虑了壳体和各个传动件引起的系统变形的基础上,分析得到了主减速器齿轮副的传递误差、齿面接触斑点、振幅等评价驱动桥动力学特性的因素,以及驱动桥整体传动系统的振动频率与动态响应和桥壳的受力变形。研究了主减速器弧齿锥齿轮振动变形对驱动桥系统动力学特性的影响。针对分析结果中出现的轮齿啮合质量的缺陷,进行齿轮的修形优化。对比修形前后的分析结果,提出了改善齿轮副传动质量的修形方案。该方案提升了驱动桥主减速器的动力学特性,并为驱动桥整体动力学性能改善和壳体的结构优化提供了依据。
Based on the theory of multi-dynamics,an analysis model of driving axle transmission system is built up.The system deflection caused by driving axle housing and components are synthetically considered.Transmission error,contact pressure,amplitude of main reducing gear,whole transmission system vibration frequency,dynamic response and deformation from housing are generated from dynamics system analysis.The influence of vibration and deformation of spiral bevel gears on the dynamic performance of driving axle is studied.The defect of meshing quality is found,and some improvement measures are put forward.Compared with the analysis results of the spiral gear without optimization,the solutions of optimization can improve the dynamic properties of main reducing gear.The solutions also provide the basis of optimization for dynamic performance of complete driving axle.
