低速载货汽车车架和悬架的设计生本科生(论文)-学位论文.doc

山东科技大学大学本科生毕业设计（论文）PAGE\*MERGEFORMAT4Ⅰ低速载货汽车车架和悬架的设计摘要本课题结合生产实际，对低速载货汽车车架及悬架系统进行了设计。设计内容主要包括：参与总体设计；车架、悬架结构型式分析和主要参数的确定；车架、悬架结构设计。整个设计过程遵循以下原则和技术标准：规范合理的型式和尺寸选择，结构和布置合理；保证整车良好的平顺性能。工作可靠，结构简单，装卸方便，便于维修、调整；尽量使用通用件，以便降低制造成本；在保证功能和强度的要求下，尽量减小整备质量。低速载货汽车上用得比较广泛的是边梁式车架和非独立悬架，因为边梁式车架和非独立悬架结构简单，比较经济实用，便于维修和改装。考虑到车架和悬架在整车设计中的作用，首先进行了车架、悬架的总体设计，然后对车架、悬架结构进行了设计，最后对车架、悬架的结构进行了受力综合分析，在次基础上确定了它们的主要参数。关键词：低速货车;车架;悬架;设计ABSTRACTThistopiccombinedproduction,thelowspeedtruckframeandsuspensionsystemhavebeendesigned.Themaincontentofthedesigninclude:thedesignoftheparticipationsystem,analysisofthestructurepatternoftheframeandsuspensionanddeterminationofthemainparameter,designofthestructureoftheframeandsuspension.Duringtheentiredesignprocess,theprinciplesandthetechnicalstandardsarefollowed:thereasonablepatternandthesize,thestructureandarrangement;thegoodsmoothperformanceoftheentirevehicle;withreliablework,simplestructure,loadingandunloading,advantageousfortheserviceandtheadjustment;asfaraspossiblegeneralparts,inordertoreducethecostoftheproduction,thefunctionandtheintensityrequestareguaranteed,thequalityisreducedasfaraspossible.Thesideframeandnon-independentsuspensionareusedquitewidelyonthelowspeedtruck,becausethesideframeandnon-independentsuspensionstructurearesimple,economicalandpractical,advantageousfortheserviceandtherefit.Consideredthefunctionoftheframeandsuspensionintheentirevehicledesign,firstlythatthewholeoftheframeandsuspensionsystemiscarriedondesigning,thenthestructureoftheframeandsuspensionhavebeencarriedondesigning,finallythestressgeneralizedanalysisofthestructureoftheframeandsuspensionhasbeencarriedon,theirmainparameterhasbeendeterminedintheinferiorfoundation.Keywords：LowSpeedTruck;Frame;Suspension;design目录TOC\o"1-3"\h\z\uHYPERLINK"file:///C:\\Documents%20and%20Settings\\沈保成\\桌面\\0210110131%20刘小锋\\设计封面和目录.doc"\l"_Toc137020151#_Toc137020151"摘要PAGEREF_Toc294175822\hIAbstractPAGEREF_Toc294175823\hII目录Ⅲ第1章前言1.1车架的发展1.2悬架的发展HYPERLINK"file:///C:\\Documents%20and%20Setti
