机械式六档变速器设计说明书（含10张CAD图纸）.doc

摘要 变速器是汽车传动系中的主要部件之一。主要用来改变发动机传到驱动轮上的转矩和转速，它设计的好坏直接影响到汽车的实际使用性能。变速器由变速传动机构和变速操纵机构两部分组成。变速传动机构的主要作用是改变转距和转速的数值和方向；操纵机构的主要作用是控制传动机构，实现变速器传动比的改变，即实现换挡，以达到变速变距。本题目主要进行三轴六挡机械式变速器的设计，包括齿轮传动部分并进行相关的计算与校核Abstract Transmission in the automotive transmission lines, one of the most important components.mainly used to change the engine driving wheel on the spread of torque and speed, Transmission speed by a variable speed transmission and control mechanism of two parts. The main role of the variable-speed transmission is to change the value of torque and rotational speed and direction; manipulation of the organizations main role is to control the transmission mechanism, transmission gear ratio to achieve the exchange, that is, to achieve shift in order to achieve variable-speed pitch. This subject, mainly for automotive six-axis mechanical transmission gear structural design, including the gear drive parts, control of part of the, etc., and the associated calculation and verification, through the design and verification,The main structure of the transmission line design standards, parts intensity reached the use requirements.Automobile transmission is by changing the transmission ratio, the engine crankshaft in turn refused to change and adapt at the start, acceleration, road traffic and to overcome the obstacle of different driving conditions and speed of the drive wheel traction with different demands and needs. Popular divided into manual transmission (MT), automatic transmission (AT), manual / automatic transmission, non-stage transmission. Automotive Transmission usually after the former cabinet and cabinet composition. Keywords:Transmission,Axis 6 block,gear ratio,gear wheel （说明书含80页）需要整套联系 QQ 605039661 注:此说明书含部分内容，需要完整版联系QQ 605039661 目录 摘要 1 Abstract 1 目录 3 第1章 绪论 5 1.1 选题的背景及意义 5 1.2 变速器的功用和要求 7 1.3 国内外研究状况 8 1.4 部分已知的主要参数 10 1.5 本章小结 11 第2章 机械式变速器的概述及其方案的确定 12 2.1 变速器的功用和要求 12 2.2 变速器结构方案的确定 12 2.2.1 变速器传动机构的结构分析与型式选择 12 2.2.2 倒挡传动方案 17 2.3 变速器主要零件结构方案的分析 18 2.3.1 齿轮
