速騰和福克斯是A級(jí)車(chē)中的兩大競(jìng)爭(zhēng)車(chē)型，其中一個(gè)賣(mài)點(diǎn)就是都采用了獨(dú)立的后懸掛。速騰的叫“多連桿后懸掛”，福克斯的叫“SLAControlBlade后懸掛”。經(jīng)過(guò)對(duì)比，發(fā)現(xiàn)兩個(gè)懸掛有很多相似之處。FordControlBladeSuspensionAlotofattentionandmarketinghasbeencomingoutofFordrecentlyabouttheirnewControlBlade™rearsuspension.DetailsandengineeringfactsarepredictablysketchybuttheglossymarketingbrochureswilltellyouthisrevolutioninrearsuspensionwillmakeyourFordFocushandlebetter,griptheroadbetter,andbrakebetterthaneverythingelseontheroad.Itwarrantssomeinvestigationwhentheymakeclaimslikethat,butitturnsoutwhattheymeanis"we'vegotanewsuspensionsystem",andnotmuchelse.Itactuallystartedoutitslifesometimearound1998inFordofAustraliaandIbelieveHoldenhadsomethingtodowithittoo.Sincethenitsbecomefarmoremainstream.So"ControlBlade"isthesnappymarketingnamethatFordusetodescribetheirnewsystem.Itsoundsgood,looksgoodonpaper,andhasanauraof21stcentury-nessaboutit."Blade".Ooh.Cool.Therealityisn'tquitesocoolthough-controlbladeisbasicallyanevolutionoftrailing-armsuspension.HoweveritsstillaninterestingdevelopmentanditdoesservethepurposeforwhichForddesignedit.TheprimarypurposeofControlBladesuspensionistoincreasetheinteriorspaceavailableinthevehicle.Mostsuspensionsystemsusedindailydrivershavestruttowersfrontandrear.Inthefrontit'snotreallyaproblem,butintherearitimpedesonboot(ortrunk)space.Fordwantedtogivemorespaceinthebackandneededtofindagoodwaytoremoveorreducethesizeofthestruttowers.TheresultistheirControlBladesystemwhichinessenceseparatestheshockabsorberfromthesprings.Todothis,Fordneededtouseatrailing-armtypesuspensionsothattheydidn'thaveswingarmsupunderthewheelarches.Thespringswereshortenedandmovedinboardandunderneath.Inonevariation,theshockabsorbersstillsitverticallybutthespacetheytakeupnowishugelyreducedbecausetheynolongerhavethecoilspringsaroundtheoutside.Inthesecondvariationtheshockabsorberisasubminiatureunitmountedinboardofthespringsunderneaththevehicle.I'mnotsureofthemeritsofthesuper-shortshockabsorberbutFordseemtothinkitworks.Thecontrolbladesthemselvesarebasicallythetrailingarmswhichgivelateralsupportandprovidetheverticalpivotpointfortheentireunit.TheFordspielsaysthisaboutControlBlade："Ithasthekeyfunctionofpromotingrideandreducingroadnoisetransmission,whileprovidingthefreedomtoletthelaterallinksdefinetoeandcamberbyabsorbinganyrearwardforcesandallowingtherestofthesuspensiontodoit'sjobuninterrupted.EffectivelyisolatingthehandlingcomponentsofthenewIRSfromtheroadnoiseandimpactharshnesscomponentsofthesuspension.".InEnglish?Itmeansbetterhandlingandlessroadnoise.Lookingatthebasicdesignit'snotdifficulttoseethatthissystemhasamuchlowercentreofgravitythanaMacphersonstrut(forexample).LowerC-of-Ginavehicleisalwaysagoodthing.ThegeometryoftheControlBladesystemalsoprovidessignificant'anti-dive'underbrakingforce,whichmeansathecarbodywilldivelesswhenyoujumponthebrakeswhichinturntranslatesintomorewell-behavedbrakingresponse.LowerC-of-G,lessrollandlesspitchduringbrakingalladduptobetterhandling,althouthwhethertheaveragedriverwouldnoticeornotisadifferentmatter.Anotherfunctionofthissystemisthatthey'veseparatedthetwobasicfunctionsofsuspension.Withthespringsandshockabsorbersbeingmountedindifferentplaces,Fordhavemanagedtooptimisethefunctionofthesecomponents.It'ssimilarinconcepttowhatBMWdidwiththeteleleverfrontsuspensiononmotorbikes-separatingbrakingfromsuspensionforces,onlyinthecontrolbladesystem,itseparatesthespringingsupportofthesuspensionfromtheshockreducingfunctionsoftheshockabsorbers.而幾乎相同的設(shè)計(jì)，大眾卻把這套懸掛系統(tǒng)叫做“四連桿獨(dú)立懸掛”。大眾的官方說(shuō)明：緊湊的四連桿后懸架結(jié)構(gòu)是PQ35平臺(tái)底盤(pán)系統(tǒng)最大的變化之處，改變了PQ34平臺(tái)上的半獨(dú)立扭桿梁式（目前很多大眾車(chē)也在用這個(gè)），而以中高檔轎車(chē)上采用的獨(dú)立式四連桿代替，大大提高整車(chē)的舒適性和操控性。四連桿后橋由以下部分組成：三個(gè)擺臂(下擺/彈簧臂8,橫拉桿7,上擺臂6)和一個(gè)縱向拖臂4組成(看圖對(duì)號(hào)入座)，每個(gè)車(chē)輪有一個(gè)橫拉桿，能獨(dú)立區(qū)分縱向和橫向的動(dòng)力傳遞，在與前懸架完美配合下，使整車(chē)具有良好的平穩(wěn)性和駕駛舒適性。后懸架不但保持著德國(guó)車(chē)的一貫硬朗，又兼具了良好的乘坐舒適性。懸架幾何結(jié)構(gòu)可產(chǎn)生中性或略帶不足轉(zhuǎn)向，有利于轉(zhuǎn)向穩(wěn)定。
