金杯阁瑞斯汽车变速箱设计
摘要
从十八世纪工业革命开始到现在，人类科技可以说是突飞猛进。而汽车作为现今我们最常用的交通代步工具，其发展也是日新月异，新兴的高科技技术层出不穷，而变速器作为汽车传动系统中的一个不可或缺的部分，有很多发展创新的空间。本设计目的旨在于对金杯阁瑞斯型号汽车的变速箱进行设计，设计的结果在理想情况下，能够正常在汽车中使用运行。在对变速器的功能和结构进行介绍的基础上，主要研究其零件工作如何配合，如何完成动力的传输和传动比的改变。
中针对变速器这一装置，在介绍分析了其功能和工作原理的情况下，完成了利用CAD对变速器总体结构的绘制。在总体结构大致正确的情况下，一边拆画其主要零件，一边查阅相关书籍分析设计其主要零件。在校核设计过程中主要参照《机械设计》等相关书籍，然后对设计结果进行逐步校核审定设计结果，最后对整体设计进行确定。
本变速器基于两轴式变速器设计，参照其他汽车变速器设计方案最终完成了本汽车的中间轴式五档变速器。虽然在诸多方面的设计比较片面不严谨，但是基本适用于工作要求。
关键词：结构分析、零件设计、动力传输。
ABSTRACT
In the long history of human development, the industrial revolution can be said to really bring mankind into a new era of mechanization and automation. From the 18th century to the present, mechanized and truly popular to our side. And the car as our most commonly used means of transportation and transportation, its development is also changing, emerging high-tech technology after another, and the transmission as an integral part of the car drive system, there are many development of innovative space.
The purpose of this design is to design the gearbox of the Jinbei Gueri model car,which requires the design result to meet the requirements of thework, and the design result can be run normally. On the basis of the introduction of the function and structure of the transmission, the mainwork of how to copewith thework, how to complete the power transmission and transmission ratio changes.
In this paper, for the transmission of this device, in the analysis of its function andworking principle of the case, try to use CAD to draw the overall structure of the transmission. In the overall structure of the case is correct,while digging its main parts,while access to relevant books to analyze the design of its main parts. In the process of checking the design of the main reference to the"mechanical design" and other related books, and then the results of the design results of the audit design results, and finally to determine the overall design.
The transmission is based on the design of the two-shaft transmission,with reference to other automotive transmission design program to complete the car's intermediate shaft five-speed transmission. Although in many aspects of the design more one-sided is not strict, but basically applicable to thework requirements.
Keywords:Structural Analysis ;Part Design;Power Transmission.
