某轻型车转向器设计
摘要
本次设计设计一款用于轻型汽车的转向器。论文首先对转向系的作用，基本
构成、要求和转向系统的总体性能进行了分析，同时对转向系的空间位置及结构
特点进行分析，确定了转向梯形的型式，简单的概述了转向传动机构。确定了转
向器的结构和布置形式，分析了转向器的啮合传动的特点和传动效率。根据汽车
工程参考某款轻型汽车的转向器的参数，对转向器进行设计，并对齿轮齿条的
齿面接触强度和齿根弯曲强度进行校核，同时利用 AUTOCAD 软件绘制装配图
和零件图。
关键词：汽车 转向系统 转向器 齿轮齿条 强度

The designe of light vehicle vergence implements
Abstract
The vergence implement design is used for light automobile originally time. Effect
that the thesis is first to vergence, the population function basically, composing ,
demanding system has carried out analysis. The characteristic has carried out analysis
on space location and structure changing to a department at the same time , simple
summary changing to transmission-mechanism. Have ascertained the structure
changing to an implement and have arranged a form, have analysed the characteristic
and drive efficiency changing to the implement falling-in drive. And the project
consults some light automobile of money vergence implement parameters according
to the automobile , design that to changing to an implement be in progress, the flank
of a tooth to gear wheel rack contacts the intensity and the curved intensity of
dedendum carrying out the core of school , makes use of the AUTOCAD software to
draw assembling picture and part picture at the same time.
