哈尔滨工业大学毕业设计（论文）-I-摘要随着大型客车市场的竞争加剧，提高设计效率、提高制动性能，使制动系工作可靠发挥汽车高速行驶的动力性能并保证行驶的安全性，降低成本等，已经成为主要的竞争手段。因此，对客车制动器的设计是非常重要的。本设计是针对CA6120D116大型客车后轮的鼓式制动器及相应驱动机构的设计。设计中采用的是S型凸轮鼓式制动器，驱动机构采用气压驱动。本文介绍了论文研究的目的和意义、鼓式制动器的各种结构型式及选择、并对相关参数及结构进行选择及设计计算，然后对制动气室进行设计计算，最后对数据强度校核。关键词：客车，制动系统，鼓式制动器，气压驱动更多设计请咨询245250987哈尔滨工业大学毕业设计（论文）-II-AbstractWiththelargebusmarketcompetition,improvethedesignefficiency,improvebrakingperformance,thebrakingsystemtoplayareliablehigh-speeddynamicperformanceofvehicleandtoensuredrivingsafety,reducecostsandsoon,hasbecomeamajormeansofcompetition.Therefore,thedesignofbusbrakesisveryimportant.ThisdesignisforCA6120D116largebusreardrumbrakeandthecorrespondingdrivemechanismdesign.ItisusedS-camdrumbrakesandpneumatic-drivendrivemechanism.Thisarticledescribesthepurposeandsignificanceoftheresearch,variousstructuraltypesofdrumbrakes,andchoice,andselecttherelevantparametersandstructureanddesigncalculations,andthenthebrakechamberdesigncalculations,thefinalstrengthcheckofdata.Keywords：Bus,BrakeSystem，Drumbrake，Pressure-driven哈尔滨工业大学毕业设计（论文）-III-目录摘要......................................................................................................................ⅠAbstract...................................................................................................................Ⅱ第1章绪论..............................................................................................................11.1论文研究的目的及意义.............................................................................11.2论文研究的方向.........................................................................................11.3制动系的功用及应满足的要求.................................................................2第2章鼓式制动器的结构型式及选择..................................................................42.1领从蹄式制动器.........................................................................................62.2双领蹄式制动器.........................................................................................82.3双向双领蹄式制动器.................................................................................92.4单向增力式制动器.....................................................................................92.5双向增力式制动器...................................................................................102.6鼓式制动器方案的确定...........................................................................102.6.1制动效能因数................................................................................102.6.2本设计中鼓式制动器的优选........................................................11第3章制动器的主要参数及选择........................................................................133.1制动力与制动力分配系数.......................................................................133.2同步附着系数...........................................................................................163.3制动强度和附着系数利用率........................................................
