附錄1譯文無級變速器的行星齒輪機構(gòu)采用雙行星齒輪機構(gòu),行星架上固定有內(nèi)、外行星齒輪和右支架,其中右支架是通過螺栓固定在行星架上,外行星齒輪和齒圈嚙合,內(nèi)行星齒輪和太陽輪嚙合。它們可以實現(xiàn)前進和倒檔。無級變速機構(gòu)由金屬傳動帶和主、被動工作輪組成。金屬傳動帶由兩百多個金屬片和兩組金屬環(huán)組成,每個金屬片的厚度為1.4mm,在兩側(cè)工作輪擠壓力作用下傳遞動力。每組金屬環(huán)由9或12片厚度為0.18mm的帶環(huán)疊合而成,金屬環(huán)的功用是提供預(yù)緊力,在動力傳遞過程中,支撐和引導(dǎo)金屬片的運動,有時承擔(dān)部分轉(zhuǎn)矩的傳遞。主、被動工作輪由可動和不動錐盤兩部分組成?？刂葡到y(tǒng)是用來實現(xiàn)無級變速器系統(tǒng)傳動比無級自動變化的。在無級變速器系統(tǒng)中,采用機-液控制系統(tǒng)或電-液控制系統(tǒng)。它主要由油泵齒輪泵和滾子葉片泵、液壓調(diào)節(jié)閥速比和帶與輪間壓緊力的調(diào)節(jié)、傳感器油門和發(fā)動機轉(zhuǎn)速和主、從工作輪的液壓缸及管道組成,實現(xiàn)傳動無級變速的調(diào)節(jié)。速比控制、夾緊力控制和起步離合器的控制是無級變速控制系統(tǒng)的關(guān)鍵。由于無級變速機構(gòu)可提供的速比變化范圍為2.60.445左右,不能完全滿足整車傳動比變化范圍的要求,故設(shè)有中間減速機構(gòu)。無級變速器的變速原理很簡單,但也很巧妙。傳動器的主、被動工作輪的固定和可動兩部分形成V形槽,與金屬傳送帶嚙合。當主、被動工作輪可動部分作軸向移動時,改變了傳送帶的回轉(zhuǎn)半徑,從而改變傳動比?？蓜虞喌妮S向移動是根據(jù)汽車的使用要求,通過液壓控制系統(tǒng)進行連續(xù)地調(diào)節(jié),實現(xiàn)無級變速傳動。附錄2英文參考資料Continuouslyvariabletransmissionofplanetarygearmechanismbasedondoubleplanetarygearmechanismandplanetaryframefixedintheouterplanetgearandrightbracketrightbracketisthroughboltontheplanet,outerplanetgearandgearmeshingandinnerplanetgearandSunwheelgear.Theycanrealizetheforwardandreversegear.MetalV-beltcontinuouslyvariableinstitutionsandmajor,composedofpassivewheel.MetalV-beltiscomposedof200metalandtwometalring,eachsheetmetalthicknessof1.4mm,bothsidesundertheeffectofwheelpressuretransferofpower.Eachsetofmentalringby9or12thethicknessof0.18mmbandsuperimposed,functionistoprovidepre-tighteningforceofmetallicring,intheprocessofpowertransfer,supportandguidethemovementofmetal,sometimesbearpartofthetorquetransfer.ActiveandPassivebymovableandfixedbevel-wheeloftwoparts.Controlsystemisusedforcontinuouslyvariabletransmissionsystemfortransmissionratioofcontinuouslychanging.Inthecourseofcontinuouslyvariabletransmissionsystemusingaircraft-hydrauliccontrolsystemofelectric-hydrauliccontrolsystem.Rollervanepumpanditsmainoilpumpgearpump,hydrauliccontrolvalveratioandzoneandonthecompactionforceregulation,sensors,throttleandenginespeedandfromtherunnerofhydrauliccylinderandpipecompositionandrealizationofdrivingsteplessadjustment.Ratiocontrol,clampingforcecontrolandstartingclutchcontrolisthekeytocontinuouslyvariablecontrolsystem.Duetothecontinuouslyvariableratiorangeoforganizationscanprovideabout2.60.445,cannotmeettherequirementsofvehicletransmissionratioofrangeandaslowdowninthemiddleinstitution.Steplessspeedtransmissionprincipleisverysimple,butitisalsoveryclever.TransmissionmainpassivewheeloffixedandmovableformaV-shapeslotoftwoparts,andmetalconveyormesh.WhentheLordandpassivewheelpartsforaxialmoving,changetheradiusofgyrationoftheconveyorbelt,thuschangingtheratio.
