題目：寶萊轎車前輪制動(dòng)器設(shè)計(jì)姓名：班級(jí)學(xué)號(hào)：指導(dǎo)教師：摘要-I-摘要汽車制動(dòng)系的基本功用是使行駛中的汽車減速或停車，在下坡行駛的汽車的車速保持穩(wěn)定以及使已停駛的汽車在原地或坡道上駐留不動(dòng)的機(jī)構(gòu)。汽車制動(dòng)系直接影響著汽車的安全性和停車的可靠性。隨著高速公路的迅速發(fā)展和車速的提高以及車流密度的日益增大，為了保證行駛安全、停車可靠，汽車制動(dòng)系的工作可靠性顯得日益重要。也只有制動(dòng)性能良好、制動(dòng)系工作可靠的汽車才能充分發(fā)揮其動(dòng)力性能。汽車的制動(dòng)系是汽車行車安全的保證，許多制動(dòng)法規(guī)對(duì)制動(dòng)系提出了許多詳細(xì)而具體的要求，這是我們?cè)O(shè)計(jì)的出發(fā)點(diǎn)。從制動(dòng)系的功用及設(shè)計(jì)的要求出發(fā)，依據(jù)給定的設(shè)計(jì)參數(shù)，進(jìn)行方案論證。對(duì)各種形式的制動(dòng)器的優(yōu)缺點(diǎn)進(jìn)行了比較后，選擇了前盤后鼓的形式。這樣既保證了較高的制動(dòng)效能又有很好的穩(wěn)性。關(guān)鍵詞制動(dòng)系；制動(dòng)盤；摩擦塊；制動(dòng)效能Abstract-II-AbstractTheautomobilebrakingsystembasicfunctioniscausesinthetraveltheautomobiletodecelerateortostop,stabilizesaswellascausesalreadytheautomobileinthedownhilltravelautomobilevehiclespeedmaintenancewhichstopstripsinkeepsthemotionlessorganizationonin-situortheslopeway.Theautomobilebrakingsystemdirectlyisaffectingthereliabilitywhichtheautomobilesecurityandstops.Increasedaybydayalongwiththehighwayrapiddevelopmentandthevehiclespeedenhancementaswellasthestreamofvehiclesdensity,inordertoguaranteethetravelissafe,stopsreliably,theautomobilebrakingsystemoperationalreliabilityappearsdaybydayimportantly.Alsoonlythebrakingqualitytobegood,thebrakingsystemworkreliableautomobilecanfullydisplayitspowerperformance.Theautomobilebrakingsystemistheautomobiletrafficsafetyguarantee,manyappliedthebrakethelawsandregulationstoproposetothebrakingsystemmanydetailedandconcreterequest,thiswasastartingpointwhichwedesigned.Embarksfromthebrakingsystemfunctionandthedesignrequest,thebasisassignsthedesignvariable,carriesontheplanproof.Hascarriedonthecomparisonaftereachkindofformbrakegoodandbadpoints,afterhaschosenthemorningmarketthedrumform.Likethisbothhadguaranteedhigherappliesthebrakethepotencyandtohavetheverygoodstability.KeywordsBrakingsystemBrakediscDragblockBrakingquality目錄-1-目錄摘要.IAbstract.II第1章緒論.31.1汽車制動(dòng)系概述.31.2汽車制動(dòng)器的工作原理.51.3畢業(yè)設(shè)計(jì)的目的和意義.6第2章制動(dòng)器結(jié)構(gòu)型式及選擇.82.1鼓式制動(dòng)器的結(jié)構(gòu)型式及選擇.82.2盤式制動(dòng)器的結(jié)構(gòu)型式及選擇.92.2.1定鉗盤式制動(dòng)器.102.2.2浮鉗盤式制動(dòng)器.122.2.3全盤式制動(dòng)器.122.3盤式和鼓式制動(dòng)器比較.13第3章制動(dòng)系的主要參數(shù)及其選擇.153.1制動(dòng)力與制動(dòng)力分配.153.1.1制動(dòng)時(shí)前、后輪的地面法向反作用力.153.1.2前、后制動(dòng)器制動(dòng)力的理想分配曲線.173.2具有固定比值的前、后制動(dòng)器制動(dòng)力與同步附著系數(shù).193.3制動(dòng)器的制動(dòng)力矩.203.4利用附著系數(shù)與制動(dòng)效率.21第4章制動(dòng)器的設(shè)計(jì)計(jì)算.244.1原始數(shù)據(jù)和技術(shù)參數(shù).244.2參數(shù)選擇以及數(shù)據(jù)計(jì)算.244.2.1盤式制動(dòng)器主要參數(shù)的確定.244.2.2摩擦塊磨損均勻性驗(yàn)證.254.2.3緊急制動(dòng)時(shí)前后輪法向反力及附著力距.254.2.4同步附著系數(shù)的確定.264.2.5制動(dòng)器的效率.274.2.6制動(dòng)力矩以及盤的壓力.274.2.7同步附著系數(shù)的驗(yàn)算.284.2.8摩擦襯塊的磨損特性的驗(yàn)算.28第5章制動(dòng)驅(qū)動(dòng)機(jī)構(gòu)的結(jié)構(gòu)型式選擇與設(shè)計(jì)計(jì)算.295.1制動(dòng)驅(qū)動(dòng)機(jī)構(gòu)型式.295.1.1簡(jiǎn)單制動(dòng)系.295.1.2動(dòng)力制動(dòng)系.295.1.3伺服制動(dòng)系.305.2分
