本科生毕业设计（论文）摘要随着高速公路的不断发展，汽车车速的不断提高，车流密度也不断增大。现代汽车对制动系的工作可靠性要求日益提高。因为只有制动性能良好，制动系工作可靠的汽车才能充分发挥出其高速行驶的动力性能并保证行驶的安全性。由此可见，本次制动系统设计具有实际意义。对于福田风景轻型客车的制动系统设计，首先制定出制动系统的结构方案，本设计确定采用前盘后鼓式制动器，串联双腔制动主缸，HH型交叉管路布置。其次计算制动系统的主要设计参数(确定同步附着系数，制动力分配系数，制动器最大制动力矩)，制动器主要参数设计和液压驱动系统的参数计算。再次利用计算机辅助设计绘制装配图，布置图和零件图。最终进行制动力分配编程，对设计出的制动系统的各项指标进行评价分析。通过本次设计的计算结果表明设计出的制动系统是合理的、符合标准的。其满足结构简单、成本低、工作可靠等要求。关键词：福田风景轻型客车；制动系统设计；前盘后鼓式制动器；制动主缸AbstractWiththecontinuousdevelopmentofhighways,thecontinuousimprovementofvehiclespeed,trafficdensityhasincreasedcontinuously.HyundaiMotorbrakeontheworkoftheincreasingreliabilityrequirements.Onlygoodbrakingperformance,thebrakingsystemofreliablecartogivefullplaytoitshigh-speeddrivingperformanceandtoensurethatthemomentumonsecurity.Evidently,thisbrakingsystemdesignofpracticalsignificance.ForthedesignofFotonViewLightBus,Firstdevelopedstructureofthebrakingsystem,thedesigndeterminedbypre-andpost-drumbrakes,dual-chambertandembrakemastercylinders,HH-cross-linelayout.Thiswasfollowedbycalculationofthemainbrakingsystemdesignparameters(attachmentcoefficientdeterminedsimultaneously,thebrakingforcedistributioncoefficient,thebiggestbrakebraketorque),themainparametersofdesignandbrakehydraulicdrivesystemparameters.Drawingonceagainusecomputer-aideddesignassemblydrawing,layoutplansandparts.Finalbrakingforcedistributionofprogramming,thedesignofthebrakingsystemofindicatorstoevaluatetheanalysis.Throughthisdesigncalculationsdesignedtoshowthatthebrakingsystemisreasonable,inlinewithstandards.Tomeetitsstructureissimple,lowcost,reliabilityrequirements.Keywords：FotonViewLightBus；BrakeSystemDesign；Qianpanhougubrake；Brakemastercylinders目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc201920158"第1章绪论PAGEREF_Toc201920158\h1HYPERLINK\l"_Toc201920159"1.1制动系统工作原理PAGEREF_Toc201920159\h1HYPERLINK\l"_Toc201920160"1.2汽车制动系统的组成PAGEREF_Toc201920160\h2HYPERLINK\l"_Toc201920161"1.3汽车制动系统的类型PAGEREF_Toc201920161\h2HYPERLINK\l"_Toc201920162"1
