更换车轮The2-piecebearingadapterdesignsimplifiesthereplacementoperationsignificantly:分体式轴箱结构显著地简化了更换过程：Thewheelsetcanberemovedwithaminimumamountofeffort.

仅用最小的努力就可以拆除轮对。Itisonlyrequiredtoremovethebearingcaporretainer,todisconnectthetractionmotorcablesandseparatethetractionmotorfromthenosesuspension.

仅需拆掉轴承盖或保持器，断开牵引电机电缆，并使牵引电机与电机吊杆分离。Dampersandtractionlinksremainwiththebogieframeassembly.

减振器和轴箱拉杆仍然与转向架构架总成保持在一起。Springsremainwiththebogieframeassembly.

一系弹簧仍然与转向架构架总成保持在一起。Theinstallationofthewheelsetdoesnotrequireafixture(ormanpower)tokeepthebearinghousingandthelinksandspringsalignedandsecuredduringliftingofthedroptable.

安装轮对时无需在升起落轮台的过程中使用工装（或人力）来保持轴箱、轴箱拉杆和一系弹簧的对位。H.D.Schaller Sept.2006D.1.Bearingadapterassembly轴箱总成(Continued续)ADVANTAGESOF2-PIECEBEARINGADAPTERDESIGN分体式轴箱结构的好处Bearingadaptersalsoofferbenefitsintermsofincreasedreliability:分体式轴箱还有益于提高可靠性：Sincedampersandtractionlinksremainwiththebogieframeassembly,thereisnoneedtore-torquethemountinghardwareofthesecomponents.Thesejointsaretorquedtospecbythemanufacturerandwillbedisconnectedonlyforcomponentreplacementoratoverhaul.Theriskofboltscominglooseissignificantlyreduced.

由于减振器和轴箱拉杆仍然与转向架构架总成保持在一起，因此无需重新用扭矩扳手拧紧这些零件的紧固件。这些连接由机车制造商按照规范紧固到规定扭矩，仅在更换这些零件或大修时才断开，因此显著降低了螺栓松动的风险。Thejournalbearingassembly(cartridgetypebearings)willnotbetouchedoropenedduringwheelsetchange.Theassemblyremainssealedwithoutanyriskofcontaminationofbearingassemblyorlubricant.

在更换轮对过程中不会接触或打开轴箱轴承总成（单元式轴承）。整个总成保持密封状态，因此没有污染轴承总成或润滑脂的风险。H.D.Schaller Sept.2006D.1.Bearingadapterassembly轴箱总成(Continued续)BEARINGADAPTERDESIGN轴箱结构Theproposedmaterialforthebearingadapteriscaststeelwithayieldstrengthof205MPaorbetter.

所建议的轴箱材料是屈服强度为205兆帕或更好的铸钢。Thefrontcoverandthelateralstopsupportwillbeintegratedintotheupperbearinghousing.Thisimprovesthestructuralintegrityofthebearingadapterandreducestheamountofflexing,whichcancauseundesiredjournalbearingloading(pinching).Thisdesignalsoeliminatesanumberofinterfaces(lessmachining,noboltedjoints,higherreliability).

在轴箱上体结构中还集成了前盖和横向止挡支承，这改善了轴箱结构的完整性并且减少了因轴箱的挠曲所造成的不希望看到的轴承附加载荷（夹紧）。该结构还消除了很多接合面，因此机加工量少，没有螺栓连接，提高了可靠性。Retainer保持器Upperhousing轴箱上体H.D.Schaller Sept.2006D.1.Bearingadapterassembly轴箱总成(Continued续)BEARINGADAPTERDESIGN轴箱结构(Continued续)Lateralthrustpadmountingface横向止推片安装面Tractionrodmountingface轴箱拉杆安装面Dampermountingface减振器安装面Shoulderswithlead-inchamfers肩部带有导入倒角Speedrecordermountingface速度传感器安装面H.D.Schaller Sept.2006D.2.PrimaryCoilSpring一系螺旋弹簧2setsofdoublecoilspringsareplacedonthebearingadapteratequaldistancetothecenterlineoftheaxle.

在轴箱上装有两套双螺旋弹簧，两侧弹簧中心到车轴中心距离相等。Staticdeflectionofthecurrentproposalisaround120mm=4.75”(Targetis100to125mm).

目前建议的静挠度约为120毫米=4.75英寸（目标是100到125毫米）TheODoftheouterspringisapproximately280mm;theheightisaround240mm.

外簧的外径约为280毫米，压缩高约240毫米。SpringswillbemadeoutofAlloyspringsteelfrompeeledbars.

弹簧将用去皮的合金弹簧钢棒材制造。Springswillhaveatravelreserve,whenverticalstopscontact(differencebetweenstopheightandsolidheight).

当垂向止挡接触时弹簧将有一个行程储备（停止高度与压并高度之差）Thecompactdesignhadbeenselected,sothatspringpocketsintheframearenotneeded.Thisreducesthemanufacturingcostoftheframe,improvesmanufacturabilityandrepresentsamorerobustdesign.

由于选择了紧凑型设计，因此无需在转向架构架上设计出弹簧套。这降低了构架的制造成本，改善了工艺性并体现了更稳健的设计。Rubberpadsareaddedbetweenthecoilspringsandthebearingadaptertoreducehighfrequencyloadtransfer.

在轴箱与螺旋弹簧之间增加了橡胶垫以减少高频载荷的传递。H.D.Schaller Sept.2006D.2.PrimaryCoilSpring一系螺旋弹簧

横向止推垫板和非金属垫板构成了轴箱与转向架构架之间传递横向载荷的途径。Thelateralthrustpadisabondedrubbercomponent,whichprovidestheproperstiffnessforgoodlateralrideandhighstability.

横向止推垫板是一个粘结的橡胶零件，它能提供适当的刚度以便实现好的横向行驶质量和高稳定性。Thelateralthrustpadismountedtothebearingadapterfrontplate.Inspection,removalandreplacementarepossiblewithoutdroppingthewheelset.

横向止推垫板安装在轴箱的前端板上。无需落轮就可以进行检查、拆除和更换。Thenon-metallicpadisboltedtoasupportonthebogieframe.

非金属垫板通过螺栓固定在位于转向架上的支撑上。Thereisasmallclearanceof1mmbetweenthethrustpadandthenon-metallicpadontheendaxles.

在端轴上的横向止推垫板和非金属垫板之间有1毫米的小间隙。Theareaiseasilyaccessible.Ifneeded,padscouldbeshimmedtomaintainclearance.

该区域易于接近。如果需要，可以通过给垫板加垫来保持间隙。Thecenteraxlewillnothavearesilientthrustpad,butasteelplatewith15mmofclearance,whichissufficientforgoodcurvingperformance.

中间轴没有弹性止推垫板，用一块钢板形成15毫米的间隙，足以提供好的曲线通过性能。Lateralthrustpad横向止推垫板Non-metallicpad非金属垫板H.D.Schaller Sept.2006D.3.Lateralstop横向止挡(Continued续)Shim垫片Padreplacement更换垫板H.D.Schaller Sept.2006D.4.VerticalstopandInterlock垂向止挡及安全锁Theverticalstopisintegratedintotheuppersectionofthebearingadapterandthelateralstopsupport.Bothfaceswillbemachined.

轴箱上部结构和（位于构架上的）横向止挡支撑上各集成有垂向止挡的一部分。两个接触面都需要加工。Currentconcepthasanominalclearanceof55mm=46%ofstaticdeflection.

目前概念的名义间隙为55毫米，是静态位移的46％。Theinterlockisinstalledin-betweentheenvelopeofthespringsandconsistsof:

减振要求应来自于行驶质量模拟。Theverticaldampershouldbeeasilyaccessibleforinspectionandreplacement.

垂向减振器应易于接近以便进行检查和更换。Fornormaltypeofservicethelifeexpectancyshouldbeequaltothebogieoverhaulinterval.

在正常维护条件下，其预期寿命应与转向架大修周期相等。Abarmountdesignispreferredasthemostreliablemethodofattachment.

由于销轴式安装方式是最可靠的连接方式所以首选这种方式。Thereshouldbesufficientstrokereserveincompressionandtension.

在压缩和拉伸过程中都应有足够的行程裕量。CURRENTCONCEPT当前概念Ridesimulationshaveshown,thatanoffsetlocationoftheverticaldampersreducedthehighfrequencyloadtransferfromthetracktothecarbody.

行驶模拟已经显示，偏置的垂向减振器能衰减从轨道向车体的高频载荷传递。Bestarrangementiswithdampersonaxle1and3leading.

最佳布置是将减振器放置在1轴和3轴偏向前进方向一侧。Currentdampingrateis6kNat0.100m/s(=1350lbs).

当前的阻尼率是在0.100m/s时为6千牛（1350磅）。Finaldampingcharacteristicwillbedefinedaftercarbodystructureandcabisolationhavebeenfinalized.

轴箱拉杆应尽可能长以降低因轴箱垂向运动对销套产生的扭转载荷和因轮对横向运动对销套产生的摆动载荷，并减少对垂向和横向刚度的影响。Verticalbearingadaptermovementshouldresultinbushingtorsionalangle.Thismeans,thebushingaxisshouldbeparalleltothelateralaxis.

轴箱的垂向运动将导致销套的扭角。这意味着，销套轴线应与横轴平行。Doublebondedrubberbushingsarepreferredtoreducethetendencytowalkout.

首选采用双面粘结的橡胶销套以降低滑出的趋势。Innermemberofbushingshouldbeofconventionalbarmountdesign.

销套的内层零件应具有传统的销轴安装结构。Thetractionrodshouldbereplaceablewithouttheneedofdroppingthewheelset.

应该可以在无需落轮的条件下更换轴箱拉杆。Thetractionrodshouldbeof“1-piecedesign”.

轴箱拉杆应该为单体式结构。Theprimarytractionrodsshallbeeasilyaccessibleforinspectionandreplacement.Itshouldnotbenecessarytoremoveothermajorcomponentstoaccessthetractionrods.

轴箱拉杆应易于接近以便进行检查和更换。在接近轴箱拉杆时应无需拆除其它主要零件。H.D.Schaller Sept.2006D.7.Primarytractionrod一系轴箱拉杆SOLUTION解决方案Tractionrodsare660mmlong,whichisagoodcompromisebetweenspaceenvelopeandbushingloading.
