货车转向桥设计摘要随着汽车行业的发展随着汽车行业的发展，作为汽车的关键零部件的转向桥也得到了相应的发展，基本以形成了专业化、系列化生产的局面。而且随着生产水平的发展，汽车的行驶速度不断提高，人们对汽车的性能要求也越来越高，如何保证既要具有较高的行驶速度又要具有良好的转向性能，就成了必须要解决的问题。本次设计为载重汽车的转向桥，此桥需要适应在不同的路况，不同的速度下使汽车保持稳定的行驶，并且使货车转向桥具有良好的稳定性和灵敏性。文中介绍了转向桥的概念，用途，总体布局，通过对前轴、转向节、转向梯形、主销等零件的尺寸和结构的设计，选择合适的材料，并对其进行强度的校核，以保证所本次设计的转向桥符合汽车道路行驶要求。关键词：转向桥；前梁；主销；定位参数The Design of Steering Axle TruckAbstractWith the development of the automotive industry, as a key component of the steering axle car has also been a corresponding development, basic to the formation of a specialized, series production of the situation. And with the development of the production level, the travel speed car continues to improve, people on the cars performance requirements are also increasing, how to ensure that it is necessary to have a higher travel speed and also has good steering performance, it becomes necessary to solve the problem. ?The design for the trucks steering axle, this bridge needs to adapt to different road conditions, different speeds making the car stable under travel, and the steering axle truck has good stability and sensitivity. This paper introduces the concept of steering axle, use, overall layout, through the front axle, steering knuckles, steering the size and structure of the trapezoid, kingpin and other parts of the design, selection of suitable materials, and its strength and the order ensure that the design of the steering axle in line with the requirements of automobile roads.Key words: initial velocity method; gas emission rate; mine panel目 录 摘要1 Abstract1第一章 绪论11.1汽车转向桥的概述11.2转向桥的研究意义11.3转向桥的发展背景21.3.1转向系统发的发展历史21.3.2我国转向系统的发展21.4转向桥的分类与基本结构31.5典型车型前桥总成结构3第二章 转向桥的零件分析52.1前梁52.2转向节62.3转向梯形62.3.1整体式转向梯形62.3.2断开式转向梯形72.4主销92.5转向节臂92.6轮毂组合92.7轴承102.7.1轮毂轴承102.7.2转向节止推轴承102.7.3主销轴承102.8转向拉杆总成102.8.1转向球头112.8.2转向直拉杆112.8.3转向横拉杆112.9前轮摆振的机理112.9.1自激摆振112.9.2受迫摆振12第三章 转向桥的设计计算133.1转向从东桥的主要零件尺寸的确定133.1.1参考车型制动系相关主要参数数值133.1.2实际参数133.2转向从动桥主要零件的校核143.2.1 前梁在制动工况与侧滑工况下的校核143.2.2转向节在制动和侧滑工况下的应力计算183.2.3主销与转向节衬套在
