前盘后鼓制动系毕业设计说明VIP专享VIP免费

摘要国内汽车市场迅速发展,然而随着汽车保有量的增加，带来的安全问题也越来越引起人们的注意，而制动系统则是汽车主动安全的重要系统之一。汽车制动系使行驶中的汽车减速或停车、使下坡行驶的汽车车速保持稳定以及使已停驶的汽车在原地(包括在斜坡上)驻留不动的机构。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，汽车制动系的工作可靠性显得日益重要。也只有制动性能良好、制动系工作可靠的汽车，才能充分发挥其动力性能。本说明书主要介绍了飞度轿车制动系统的设计。首先介绍了汽车制动系统的结构、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。关键词：制动、盘式制动器、鼓式制动器、设计参数、制动性能ABSTRACTDomesticautomobilemarketdevelopingquickly,however,withtheincreaseoftheautopossession,bringsecurityismoreandmoreattention,andbrakesystemistheimportantcaractivesafetysystemone.Thebrakeisamovingcarslowdownorstop,makethedownhillcarsspeedstabilityandmakealreadyinplaceofthecartheyoffend(includinginslope)stayfixedinstitution.Withtherapiddevelopmentofthehighwayspeedandtheimprovementoftrafficdensityandincreasesdaybyday,inordertoguaranteesafety,carbrakesystemreliabilityofworkappearincreasinglyimportant.Alsoonlybrakeperformanceisgood,brakesystemreliablecarandfullyplayitsdynamicperformancethismanualmainlyintroducesthedesignofthecarbrakesystemflyingacross.Firstthispaperreviewedtheautomobilebrakingsystemstructure,classification,andthroughtothedrumbrakediscbrakeandthestructureandtheadvantagesanddisadvantagesareanalyzed.Ultimatelydeterminetheschemeadoptshydraulicdoublecircuitwithdiskanddrumbrakesystem.Keywords:brake、diskbrake、drumbrake、designparameters、brakingperformance、目录1绪论...........................................................................................................................11.1制动系统概述................................................................................................11.1.3制动系的作用及其组成...................................................................11.1.2制动系一般工作原理.......................................................................11.1.3制动系的类型...................................................................................21.1.4制动系的设计要求...........................................................................31.2制动系统研究现状及发展趋势....................................................................62制动系统方案论证分析与选择...............................................................................82.1制动器结构型式及选择................................................................................82.1.1盘式制动器.......................................................................................82.1.2鼓式制动器......................................................................................102.2制动驱动型式选择.......................................................................................142.2.1简单制动系.....................................................................................142.2.2动力制动系......................................................................................152.2.3伺服制动系......................................................................................152.3制动主缸型式...............................................................................................162.4制动管路型...
