广东工业大学 汽车前轮转向系统的设计 摘要 本设计课题为汽车前轮转向系统的设计， 课题以机械式转向系统的齿轮齿条式转向 器设计及校核、整体式转向梯形机构的设计及验算为中心。 首先对汽车转向系进行概述， 二是作设计前期数据准备，三是转向器形式的选择以及初定各个参数，四是对齿轮齿条 式转向器的主要部件进行受力分析与数据校核， 五是对整体式转向梯形机构的设计以及 验算，并根据梯形数据对转向传动机构作尺寸设计。 在转向梯形机构设计方面。运用了优化计算工具 Matlab 进行设计及验算。 Matlab 强大的计算功能以及简单的程序语法， 使设计在参数变更时得到快捷而可靠的数据分析 和直观的二维曲线图。 最后设计中运用 AutoCAD和 CATIA作出齿轮齿条式转向器的零件 图以及装配图。 关键词 ： 转向机构，齿轮齿条，整体式转向梯形， Matlab 梯形 广东工业大学 汽车前轮转向系统的设计 Abstract The title of this topic is the design of steering system. Rack and pinion steering of Mechanical steering system and integrated Steering trapezoid mechanism gear to the design as the center. Firstly make an overview of the Steering SystemSecondly. take a preparation of the data of the design. Thirdly, make a choice of the steering form and determine the primary parameters and design the structure of Rack and pinion steering. Fourthly, Stress analysis and data checking of the Rack and pinion steering. Fifthly, design of Steering trapezoid mechanism, according to the trapezoidal data make an analysis and design of Steering linkage. In the design of integrated Steering trapezoid mechanism the computational tools Matlab had been used to Design and Checking of the data. The powerful computing and Intuitive charts of the Matlab can give us Accurate and quickly data. In the end AutoCAD and CATIA were used to make a rack and pinion steering parts diagrams and assembly drawings Keywords: Steering system， Mechanical Type Steering Gear and Gear Rack， Integrated Steering trapezoid， Matlab Trapezoid 广东工业大学 汽车前轮转向系统的设计 目录 1 绪论 ........................................................................................................................................ 1 1.1 汽车转向系统概述 ...................................................................................................... 1 1.2 汽车转向系统的国内外现状及发展趋势 .................................................................. 2 1.3 研究内容及论文构成 ...............................................................................................
