Dual Clutch Transmission (Dual Clutch Transmission) DCT yog qhov sib txawv ntawm qhov tsis siv neeg kis kab mob dav dav, nyem qhov no ntxiv ib daim duab los piav qhia tias nws yog raws li kev sib kis ntawm phau ntawv siv tsis siv neeg kis, ntxiv rau qhov yooj yim ntawm phau ntawv kis tau tus mob. thiab kev nplij siab ntawm kev sib kis tsis siv neeg Tsis tas li ntawd, nws tseem tuaj yeem muab lub zog tsis muaj kev cuam tshuam. Cov tsoos phau ntawv kis tau tus mob siv ib tug clutch. Thaum hloov lub zog, tus neeg tsav tsheb yuav tsum tau nqis los ntawm lub clutch pedal kom lub zog ntawm lub zog sib txawv koom nrog hauv kev ua haujlwm meshing, thiab lub zog tsis sib xws thaum lub sijhawm hloov, uas ua rau cov khoom tso tawm tsis sib xws. .
Taw qhia
Lub tshuab tseem ceeb ntawm DCT tsuas yog nyob hauv tes ntawm BorgWarner hauv Tebchaws Meskas thiab Schaeffler hauv Tebchaws Yelemees. BorgWarner yog tus muab cov thev naus laus zis tseem ceeb rau VW thawj tiam rau-ceev DSG (VW's DCT), muab cov khoom ntub ob-clutch rau VW DSG. Lub caij nplooj ntoos hlav no, Volkswagen nthuav tawm lub cim tshiab ntawm qhuav xya-ceev dual-clutch kis tau tus mob los ntawm LuK, ib feem ntawm Lub Tebchaws Yelemees Schaeffler Group.
txoj cai
Lub DCT muaj ob qhov kev tswj tsis siv neeg clutches, uas yog tsav los ntawm kev tswj hluav taws xob thiab hydraulic siab, thiab tuaj yeem tswj kev ua haujlwm ntawm ob lub clutches tib lub sijhawm. Thaum cov kis tau tus mob ua haujlwm, ib txheej ntawm lub zog tau koom nrog, thiab thaum lub iav hloov mus los, lub zog ntawm cov txheej txheem tom ntej ntawm lub zog tau raug xaiv, tab sis lub clutch tseem tsis raug; Thaum hloov, lub clutch yuav tshem tawm lub zog siv, Tib lub sijhawm, lwm qhov kev sib koom ua ke yog raug xaiv ua ntej, kom ntseeg tau tias tsawg kawg ib txheej ntawm lub zog yog tso tawm lub zog thaum lub sijhawm ua haujlwm tag nrho, kom tsis muaj lub zog cuam tshuam. Txhawm rau koom tes nrog cov haujlwm saum toj no, cov ncej tsav ntawm DCT tau muab faib ua ob ntu thaum tsiv, ib qho yog lub zog tsav thiab lwm qhov yog lub tog raj kheej kheej. Lub zog tsav ncej txuas rau 1st, 3rd, 5th thiab thim rov qab gears, thaum lub hollow driveshaft txuas rau 2nd, 4th thiab 6th gears. Cov ncej tsav ua kom tsis muaj kev cuam tshuam. Piv nrog rau cov tsoos phau ntawv kis tau tus mob, DSG yog yooj yim dua rau siv, vim hais tias nyob rau hauv qhov kawg tsom xam, nws tseem yog ib tug tsis siv neeg kis tau tus mob, tab sis siv cov tshiab technology ntawm DCT, uas ua rau cov phau ntawv kis tau tus mob tsis siv neeg ua hauj lwm, thiab zoo heev txhim kho cov roj kev lag luam. ntawm lub tsheb. Kev hloov pauv hloov pauv hloov tau nrawm dua thiab smoother, nrog kev xa tawm tsis muaj kev cuam tshuam. Raws li cov yam ntxwv thiab hom kev ua haujlwm ntawm DCT, DCT system tuaj yeem coj tus neeg tsav tsheb zoo li tsav tsheb sib tw. Tsis tas li ntawd, nws tshem tawm qhov kev xav ntawm kev sib kis ntawm phau ntawv lub torque cuam tshuam thaum hloov lub zog, ua rau kev caij tsheb ntau dua. Raws li nws txoj kev siv phau ntawv sib kis raws li lub hauv paus thiab nws cov qauv tsim tshwj xeeb, DCT tuaj yeem tiv taus torques txog 350 Nm,
technical keeb kwm
Xyoo 1940, Darmstadt University tus xibfwb qhia Rudolph Franke patented thawj ob-clutch kis tau tus mob, uas tau raug sim rau cov tsheb thauj khoom tab sis tsis tau muab tso rau hauv ntau lawm. Tom qab ntawd Porsche kuj tau tsim dual-clutch kis tau tus mob (PDK Porsche Doppel Kupplungen) nplooj siab rau kev sib tw. Txawm li cas los xij, nyob rau lub sijhawm ntawd, DCT / PDK thev naus laus zis tsis tau ua tiav rau hauv ntau lawm. Nyob rau hauv 1985, Audi siv dual-clutch technology rau kev sib tw Circuit Court, uas yog hu ua "Audi Sport Quattro S1 sib tw tsheb nrog dual-clutch technology". Lub tshuab hluav taws xob dual-clutch tau ua rau Audi mus rau hauv qhov kev sib tw loj hauv lub sijhawm ntawd thiab yeej ntau qhov kev sib tw. Los ntawm lig 1990s, Volkswagen thiab BorgWarner tau ua haujlwm ua ke los tsim thawj DualTronic(R) thev naus laus zis dual-clutch kis tau tus mob tsim nyog rau kev tsim khoom loj thiab kev siv tsheb loj. BorgWarner tau hloov DCT rau hauv kev sib kis tau zoo heev los ntawm kev siv cov khoom siv hluav taws xob-hydraulic tshiab. Xyoo 2002, DCT tau siv rau German Volkswagen Golf R32 thiab Audi TT V6. Xyoo 2003, nws tau nce qib mus rau lwm cov qauv xws li Golf. Nyob rau hauv 2004, lub DCT yog thawj match nrog ib tug TDI diesel cav nyob rau hauv lub German Volkswagen Touran. DCT tau dhau los ua "kev nyiam tshiab" hauv Tebchaws Europe vim nws txoj kev lag luam roj zoo heev. BorgWarner txoj haujlwm tshiab DCT tau teem sijhawm los tsim khoom rau xyoo no (2007), feem ntau yog rau cov neeg nrog caij tsheb thiab cov kis las, nrog rau kev tsim khoom txhua xyoo ntawm 600,000 teeb.
Kev faib tawm
ntub dual clutch kis tau tus mob, qhuav dual clutch kis tau tus mob
Kev siv technology
Thaum BorgWarner tau ua tiav nws cov phiaj xwm tshaj tawm thaum lub Kaum Ib Hlis 2007, nws xav tias yuav muab nws cov thev naus laus zis DualTronic(R) rau 2.3 lab dual-clutch kis tau tus mob txhua xyoo. Qhov kev loj hlob zoo kawg li no tau tsav los ntawm thawj cov npe ntawm lub tuam txhab dual-clutch kis tau tus mob thev naus laus zis, uas tau yeej kev lag luam los ntawm kev sib kis thiab cov tuam txhab tsheb thoob ntiaj teb, suav nrog Volkswagen, Audi, Bugatti, Shanghai Automotive Industry Corporation thiab Nissan cov haujlwm thiab Getrag cov haujlwm nrog. 5 ntiaj teb no automakers.
