汽车制动系设计毕业论文.doc

摘要随着高速公路的迅速发展和车速的提高以及车流密度的日益增大，为了保证行车安全、停车可靠，汽车制动系的工作可靠性显得日益重要。本说明书主要介绍了捷达轿车制动系统的设计。首先介绍了汽车制动系统的发展、结构、分类，并通过对鼓式制动器和盘式制动器的结构及优缺点进行分析。最终确定方案采用液压双回路前盘后鼓式制动器。除此之外，它还介绍了前后制动器、制动主缸的设计计算，主要部件的参数选择及制动管路布置形式等的设计过程。关键字：制动；鼓式制动器；盘式制动器；液压AbstractWiththerapiddevelopmentofExpresswayandincreasethespeedandtrafficdensityincreasingdaybyday,inordertoguaranteethetrafficsafety,parking,automotivebrakingsystemworkingreliabilitybecomesmoreandmoreimportant.Thispapermainlyintroducesthedesignofbrakingsystemofthejettatypeofcar.Fistofall,brakingsystem’sdevelopment,structureandcategoryareshown,andaccordingtothestructures,virtuesandweaknessofdrumbrakeanddiscbrake,analysisisdone.Atlast,theplanadoptinghydroidtwo-backwaybrakewithfrontdiscandreardrum.Besides,thispaperalsointroducesthedesigningprocessoffrontbrakeandrearbrake,brakingcylinder,parameter’schoiceofmaincomponentsbrakingandchannelsettings.Keywords:braking;brakedrum;brakedisc;hydroidpressure目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc312224418"摘要PAGEREF_Toc312224418\hIHYPERLINK\l"_Toc312224419"AbstractPAGEREF_Toc312224419\hIIHYPERLINK\l"_Toc312224420"第1章绪论PAGEREF_Toc312224420\h1HYPERLINK\l"_Toc312224421"1.1制动系统绪论PAGEREF_Toc312224421\h1HYPERLINK\l"_Toc312224422"1.2汽车制动系应满足如下要求：PAGEREF_Toc312224422\h2HYPERLINK\l"_Toc312224423"第2章制动系统方案论证分析与选择PAGEREF_Toc312224423\h5HYPERLINK\l"_Toc312224424"2.1制动器形式方案分析PAGEREF_Toc312224424\h5HYPERLINK\l"_Toc312224425"2.2鼓式制动器PAGEREF_Toc312224425\h5HYPERLINK\l"_Toc312224426"2.3盘式制动器PAGEREF_Toc312224426\h8HYPERLINK\l"_Toc312224427"2.4制动驱动机构的结构形式选择PAGEREF_Toc312224427\h9HYPERLINK\l"_Toc312224428"2.4.1简单制动系PAGEREF_Toc312224428\h9HYPERLINK\l"_Toc312224429"2.4.2动力制动系PAGEREF_Toc312224429\h9HYPERLINK\l"_Toc312224430"2.4.3伺服制动系PAGEREF_Toc312224430\h10HYPERLINK\l"_Toc312224431"2.5液压分路系统的形式的选择PAGEREF_Toc312224431\h11HYPERLINK\l"_Toc312224432"第3章制动系统设计计算PAGEREF_Toc312224432\h13HYPERLINK\l"_Toc312224433"3.1制动系统主要参数数值PAGEREF_T
