汽车制动系的理论分析

东北大学本科生毕业设计（论文）专用纸I摘要随着社会的飞速发展，科技越来越发达，世界也变得越来越小了，造成这个现象的基本原因就是交通工具的发展和普及，尤其是汽车的应用，灵活高速的汽车给我们的生活带来了极大便利。一方面，轿车变的越来越重、动力越来越大；另一方面，人们越来越强调汽车驾乘的舒适性和安全性。因而，作为能保证汽车安全行驶的组成部分之一——制动系，有必要对它的组成构件进行较为详尽的设计计算和理论分析。本文系统详细的介绍了汽车制动系的结构型式及其主要构件的设计计算，阐述了制动器的两种结构型式及选择和各自的工作原理、制动系的主要参数及其选择、制动器主要零部件的结构设计和分析计算、制动驱动结构的结构型式选择与设计计算、制动力分配的调节装置以及辅助制动系等。并且通过以上的比较分析，在经济可靠的基础上选择归纳了Mazda6轿车制动系主要构件的结构与参数，予以最为合理的配置。其中重点介绍了汽车车制动系的主要构件——浮钳盘式制动器、液压双会路制动主缸的分析计算和防抱死系统、驱动防滑系统的理论分析。论文的最后对摩擦衬片的摩擦特性进行了校核。关键词：汽车制动系理论分析东北大学本科生毕业设计（论文）专用纸II内容摘要或文献综述：AbstractAsthesocietyismakinggreatprogress,scientifictechnologybecomesmoreandmoredeveloped,andtheworldbecomessmallerandsmaller.Thebasiccauseofthisisthedevelopmentandpopularizationoftransportations,especiallytheapplicationofautomobiles,whichbringgreatconveniencetoourlives.Ononehand,whatthecarchangesisheavierandheavier,motiveforceisgreaterandgreater;Ontheotherhand,peopleemphasizecomfortablenessandsecuritythattheautomobiledrivesmoreandmore.Therefore,asguaranteeingoneofthecomponentsthattheautomobilegoessafely--thebrakesystem,itisnecessarytocarryonexhaustivedesigningcalculationandtheoryanalysisforcompositioncomponent.Thistextmainlyintroducesthestructurepatternofthebrakesystemanditsdesigningcalculationofmaindepartments,andexplainstwokindsofstructurepatternsandchoosingandone'sownoperationprincipleofthebrake,mainparameterofthebrakesysteminthedepartmentandchoosing,structuraldesignandcalculationofthemainsparepartofthebrake,applyingthebrakeurgesthestructurepatternofthestructuretochooseanddesignandcalculate,makestheregulationdevicethatpowerdistributesandappliesthebrakeinthedepartmentetc.Throughcomparativeanalysisoftheabove,isitsumupMazda6carapplythebrakestructureandparameter,departmentofmainmembertochooseonthebasisofthethingthateconomyisreliable,inordertoreachanddisposebest.Especially,itintroducesthemainmemberofthedepartmentofthebrakesystemamongthem--Floatpincersrecordsoftypebrake,hydraulicpressurepairsofmeetingwayapplythebrakeanalysisofmastercylindercalculatewithanti-lockbrakingsystem,urgeslipresistancesystematictheoryanalyse.Andhavecheckedtorubingthefrictioncharacteristiclinedwithsliceattheendofthethesis.Keyword:AutomobileThebrakesystemTheoriesanalysis东北大学本科生毕业设计（论文）专用纸III目录摘要..................................................................................................................................IAbstract...........................................................................................................................II第一章绪论....................................................................................................................11.1引言....................................................................................................................11.2制动装置概述....................................................................................................11.2.1制动装置各系统及其功能.........................................................................21.2.2制动系组成部分及功能.............................................................................31.2.3对制动装置的要求.....................................................................................3第二章制动器综述........................................................................................................52.1制动器及其材料的发展历史简介....................................................................52.2汽车制动器的评价指标....................................................................................72.3鼓式制动器的工作原理....................................................................................82.4盘式制动器的工作原理....................................................................................92.4.1制动过程的工作原理.................................................................................92.4.2盘式制动器制动力矩的计算...................................................................112.5现代鼓、盘式制动器优缺点的比较..............................................................122.6理想的制动系统..............................................................................................14第三章汽车制动驱动机构的选择..............................................................................173.1制动驱动机构的结构形式及分类..................................................................173.1.1简单制动系...............................................................................................173.1.2动力制动系...............................................................................................183.1.3伺服制动系...............................................................................................193.1.4制动管路的多回路系统...........................................................................203.2Mazda6轿车制动驱动机构的选择.............................................................21第四章汽车制动器主要零件的结构设计及计算......................................................244.1制动盘的设计..................................................................................................244.2制动钳的设计..................................................................................................274.2.1制动器最大制动力矩的确定............................................
