齿轮齿条转向器设计.doc

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式 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 toa 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 ofa 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.
