车辆毕业设计-东风摆臂式垃圾车设计(全套CAD图纸)

摘要垃圾车在现代生活中起到的作用越来越大，越来越被人们的重视。现代的垃圾车设计在专用车设计中的占有的地位也越来越高。目前，垃圾车设计普遍存在着价位过高，与当前垃圾车的实际接受能力存有一定的距离，致使高消费的垃圾专用车的消费量较小。本设计从市场现实需求角度出发，看重实际，把设计功能较完善合理，充分满足功能要求作为设计目标。在设计中,积极使用新型材料、降低成本价格,以期生产出占有市场优势,功能全，价格低，市场需求量较多的实用型摆臂垃圾车。本设计中的主要工作及过程如下：首先进行了专用车辆的发展现状的简要的概述，接下来就是方案的分析与选择，其中包括底盘、副车架以及托架的选择设计，总布置方案的分析和确定。然后进入了专用装置的设计，有液压系统的设计、取力器的选用以及摆臂的设计等，最后是对各种装置的校核和汽车总性能的计算。关键词：专用汽车；摆臂式垃圾车；液压系统；摆臂ABSTRACTGarbagetrucktherolewhichplaysinthemodernlifeisgettingbiggerandbigger,moreandmorebypeople'svalue.Themoderngarbagetruckdesignthestatuswhichholdsintheprivatecardesignisalsogettinghigherandhigher.Atpresent,garbagetruckdesignuniversalexistencechangestothehighconsumption,hascertainlycertainlywiththecurrentactualgarbagetruckmarketdemandisuncoordinated,thecausehighconsumption'strashprivatecar'sconsumptionquantityissmall.Regardsthereality,frommarketrealisticdemandangleembarking,isperfectthedesignfunctionreasonably,insatisfiesthefunctionrequestinthefoundation,usesthenewmaterial,totruncatethelowprice,toholdthemarketsuperioritypositivelytotakethedesignideaandthestartingpoint,producesthefunctionentire,thecostislow,themarketdemandmanypracticalsuspendsthearmgarbagetruck.Themaincontactofthedesignasfollows:first,itintroducesthespecial-purposeautomobile'sdevelopment;secondly,itintroducestheanalysisandchooseoftheproject;theprojectincludesthedesignofthechassis,theassistantframe,thebracketandensuringthetotalproject.Thirdly,itintroducesthedesignofspecialequipment,includingthedesignofhydraulicpressure,thechooseoftheimplementandthedesignofthewavingarmofrubbishtruck.Finally,itchecksallthekindsofequipmentandcalulatesthecapabilityofthespecial-purposeautomobile.Keywords：Special-PurposeAutomobile;TheWavingArmOfGarbageTruck;HydraulicSystem;SuspendingArm目录摘要......................................................................................................................................ΙABSTRACT.......................................................................................................................Ⅱ第1章绪论........................................................................................................................11.1专用汽车的发展......................................................................................................11.2专用汽车概念和分类..............................................................................................31.3专用汽车设计要求..................................................................................................31.4摆臂式垃圾汽车的设计内容..................................................................................5第2章东风摆臂式垃圾汽车底盘的选取................................................................62.1底盘的选取...................................................................................................................62.1.1汽车底盘选型要求...........................................................................................62.1.2底盘选型...........................................................................................................62.1.3底盘的选取.......................................................................................................72.2选用的底盘主车架的尺寸...........................................................................................82.3摆臂垃圾车质量参数的估算.......................................................................................82.4本章小结.......................................................................................................................8第3章摆臂式垃圾车车厢结构设计.......................................................................103.1车厢设计....................................................................................................................103.2车厢车斗的外形设计................................................................................................113.2.1厢斗形状的确定...............................................................................................113.2.2厢斗的尺寸设计...............................................................................................123.2.3厢斗选材...........................................................................................................123.3摆臂式垃圾车举升机构的设计................................................................................133.3.1摆臂液压缸的选用...........................................................................................133.3.2摆臂的设计.......................................................................................................143.3.3摆臂的受力分析...............................................................................................153.3.4摆臂的设计计算与校核...................................................................................183.4支腿的设计.................................................................................................................213.5总体结构设计.............................................................................................................223.6本章小结.....................................................................................................................23第4章摆臂式垃圾车副
