林德叉车H25-5结构分析与保养

-1-摘要林德叉车具有装卸和搬运功能，机动灵活，能适应多变的装卸搬运要求，普遍适用于港口、车站、货场、车间、仓库、油田及机场等处，还可以进入船舱和集装箱内进行装卸作业，除此之外，还广泛应用于军事部门和特殊防爆部门，有的车辆可无人驾驶，到人员不断接近的地方工作适用于柔性加工系统，总之，随着物流技术的不断发展和工业化水平的提高，叉车使用范围将日益扩大，成为一种产量与品种很多的装卸搬运机械。本叉车是参照市场上已有产品林351系列H30D叉车介绍，基本参数与相近，最大载重量也为3吨，本论文主要介绍了动力系统、传动系统、转向系统、提升系统，操纵系统和其他附属设施，其中传动系统的静压传动系统和双踏板系统为创新点。现代叉车技术发展的主要趋势是充分考虑舒适性、安全可靠性和可维护性,产品专业化、系列多样化,大量应用新技术,完善操控系统,重视节能和环保,全面提升产品的性能和品质。通过对国际国内叉车造型设计的现状分析，运用工业设计的理论和方法，研究了叉车造型设计的要素及设计原则：造型要求简洁明快、线条流畅，以体现车身的力度感与坚实稳重的感；色彩．力求单纯，给人以轻松、愉悦的感觉，主色调以明度较高的黄色、橙色为宜；车身前后左右要求有宽大的玻璃，仪表具有良好的可读性。研究结果对叉车设计具有重要的实际指导意义。关键词：叉车；静压传动；指尖操纵系统；双踏板系统ABSTRACTLindeForkliftscandohandingworks,andcanflexibilitytoadapttochangingofhandingrequirements,andgenerallyapplicabletoports,railwaystations,freightyard,workshops,warehouses,oilfieldsandtheairportandplaces,andforkliftscouldstillenterthecabinandcontainerhandingoperationswithin.Inaddition,forkliftsarealseowidelyusedinmilitaryandspecialexplosion—proofsector,somevehicleswillbeunmanned,thatofficersshouldhotworkinplacesclosetoorforFlexibleManufacturingSysterm.Inshort,asthelogisticsandtechnologicaldevelopmentandtheenhancementofthelevelofindustrialization,theuseofforkliftswillbeexpanding,anditwillbecomeayieldvarietieswithalotofmaterialhandingmachinery.TheforkliftisbasedproducesalreadyonthemarketinDalian6113BG-10-tonforkliftdesign,thebasitparameterswassimilar,forthelargestloadof10tons.Themaindeginofthedesignisthetransmission,Otherpartsonlybrieflydescribesordonotgiventhedesign.Withinthistotal,thetransmissionofthree-axis,gearbex,slidinggeartransmission,simpleandcompactstructure,bythesameagenciestoachieveavariablespeedtransmissionandreverseoperation..Themajortrendofmoderntechnologydevelopmentoftheforktruckistobefullyinconsiderationofthefriendlyoperation,thereliability,thesafety,thegoodmaintenance,thespecialization,theseries,andthediversificat,andtoadoptnewtechnology,toimprovesteeringsystem,andtofocusonenergysavingandenvironmentprotectioninordertopromotethetruck’scapacityandquality.Basedontheanalysisofcurrentstatusofinternationalanddomesticforklifttruckformdesign，thekeyelementsanddesignprinciplesinforklifttruckformdesignwasresearchedusingindustriMdesigntheoryandmethodology：ItWasputforwardthattheformofforklifttruckshouldbesimpleandlivelytllsmoothlinesinordertoconveythesenseofstrengthandsteadiness；thecolorstrivessimplicitytomakepeoplefeelpleasantandlight—mainlyusingtonesofyeHow-2-andorange；thereshouldbebigassatthefrontandbackoftrucks；thein—strumentsshouldbeeasytoread．Theresearchresultsprovidedpracticalreferenceforforklifttruckdesign．Keywords：forktruck;Hydrostatictransmission;Fingertipmanipulationsystem;Two-pedalsystem目录绪论..................................................................................................................................................................-3-1叉车的基础知识..........................................................................................................................................-4-1.1叉车的分类........................................................................................................................................-4-1.2林德叉车代号....................................................................................................................................-4-1.3叉车的基本组成................................................................................................................................-5-1.4叉车的基本原理.............................................................................................................................-5-1.5叉车的基本参数................................................................................................................................-6-1.5.1额定承载能力Q....................................................................................................................-6-1.5.2载荷中心C............................................................................................................................-6-1.5.3剩余承载能力：....................................................................................................................-6-1.5.4直角堆垛通道(最小理论)宽度(Ast):...................................................................................-6-1.5.5平衡重式叉车(四支点结构）(b12/2b13)........................................................................-7-1.6楼面承载............................................................................................................................................-7-2林德内燃叉车传动系统..............................................................................................................................-8-2.1静压传动的基本原理.......................................................................................................................-8-2.2斜盘变量柱塞泵的工作原理............................................................................................................-8-2.3斜盘柱塞马达的工作原理................................................................................................................-9-2.4静压传动的优点.......................................................
