Torque converter, CVT, dual clutch lossis ib lub tsheb clutch, qhov txawv li cas?

Audiophiles quaj rau lub hnub nyoog digital thiab nws tsis muaj qhov sib sib zog nqus vinyl sov so; Cricket cov neeg tawm tswv yim ntsuas qhov Twenty20 raws li qhov tsis muaj rog, thiab tseem ob hom kev ntxub ntxaug tsis muaj dab tsi piv rau kev nyiam kev tsav tsheb uas muaj kev cuam tshuam zoo li txuas ntxiv mus rau qhov tsis siv neeg kis tau tus mob.

Nws tsis muaj teeb meem uas Formula 1 tsav tsheb ua nrog ob lub pedals thiab ob peb paddle shifters, cov neeg tsav tsheb uas tsav tsheb sib cav tias lub neej tsis muaj nuj nqis yam tsis muaj clutches thiab pedal seev cev.

Qhov tseeb, txawm li cas los xij, yog tias feem coob ntawm cov neeg yuav tsheb zoo siab muab lawv lub thawv rau hauv D rau "Ua Me" thiab yog li kev hloov pauv tsis siv neeg tau mus txog yuav luag txhua qhov chaw, nrog Tsoom Fwv Tebchaws Chamber of the Automotive Industry (FCAI) thov tias tsis siv neeg piav qhia. tshaj 70 feem pua ​​ntawm cov tsheb tshiab muag hauv Australia.

Frankly, nws yog ib qho xav tsis thoob tias tus lej no tsis siab dua thaum koj xav tias tsawg dua 4% ntawm cov tsheb muag hauv Asmeskas muaj kev sib kis ntawm phau ntawv.

Koj tsis tuaj yeem yuav tus tshiab Ferrari, Lamborghini lossis Nissan GT-R nrog phau ntawv kis.

Yog vim li cas rau qhov no tsis yog tsuas yog tub nkeeg xwb, tab sis kuj yog lub fact tias nyob rau hauv lub lem ntawm lub xyoo txhiab tsis siv neeg kis tau tus mob los ua ntau thiab zoo meej thiab economical, tawm hauv phau ntawv xaiv rau purists thiab cov neeg pluag.

Thiab qhov kev sib cav hais tias koj tsis tuaj yeem koom nrog kev tsav tsheb yam tsis muaj kev hloov pauv yuav tsis muaj zog txhua hnub thaum koj xav tias koj tsis tuaj yeem yuav tus tshiab Ferrari, Lamborghini lossis Nissan GT-R nrog kev sib kis ntawm phau ntawv (thiab txawm tias tus qauv sportiest Porsche). tsis txhob muab sijhawm rau koj).

Yog li cas lub tsheb tau dhau los ua qhov kev xaiv tsis siv neeg thiab dab tsi ua rau lawv ntxias kom tib neeg txaus siab them ntau dua rau lawv?

Torque Converter

Qhov no yog qhov kev xaiv tsis siv neeg tshaj plaws pom nyob rau hauv cov npe nrov Mazda, nrog rau cov khoom kim tshaj Japanese Lexus.

Es tsis txhob siv lub clutch tig lub cav torque rau thiab tawm ntawm lub gearbox, nyob rau hauv cov tsoos tsheb cov kis tau tus mob txuas mus tas li siv lub torque converter.

Torque converter automatics muaj qhov zoo ntawm qhov siab torque ntawm qis revs.

Qhov kev daws teeb meem me ntsis no thawb cov kua ib ncig ntawm lub tsev kaw nrog kev pab los ntawm qhov hu ua "impeller". Cov kua dej tsav lub turbine nyob rau sab nraud ntawm lub tsev, uas hloov cov tsav mus rau lub gearbox.

Lub torque converter tsis siv neeg muaj qhov zoo sib xws ntawm ntau torque ntawm qis revs, uas yog qhov zoo rau kev nrawm los ntawm kev nres thiab hla. Acceleration los ntawm ib tug standstill yog du, zoo li yog iav hloov, uas tsis yog ib txwm muaj teeb meem nrog jerky thaum ntxov 80s-style tsheb.

Yog li cas koj ua tau hloov cov iav?

Tej zaum koj yuav tau hnov ​​​​lub sij hawm "planetary gears" nyob rau ntawd, uas suab me ntsis loj, tab sis lub hauv paus yog hais txog lub zog ntawm ib leeg, zoo li lub hli revolve nyob ib ncig ntawm lub ntiaj teb. Los ntawm kev hloov lub zog uas tig mus rau lwm tus, lub khoos phis tawj kis tau tus mob tuaj yeem hloov cov iav piv thiab qhia cov iav uas haum rau kev nrawm lossis txav.

Ib qho ntawm cov teeb meem ib txwm muaj nrog torque converters yog tias lawv tseem ceeb tsis muaj txiaj ntsig vim tsis muaj kev sib txuas ncaj qha ntawm cov tswv yim thiab cov khoom tso tawm.

Niaj hnub no "lock-up" torque converters muaj xws li ib tug neeg kho tshuab clutch los muab ntau npaum clutching.

Ntxiv ib txheej ntawm paddle shifters rau lub kauj tsheb thiab cov niaj hnub torque converters tuaj yeem ua rau muaj kev txaus siab txawm tias lawv cov kwv tij uas muaj clutch.

Ib qho clutch gearbox

Cov kauj ruam tseem ceeb tom ntej rau kev sib kis tsis siv neeg yog ib qho clutch system, uas yog qhov pib zoo li phau ntawv sib kis nrog ob lub pedals xwb.

Lub khoos phis tawj tswj hwm lub clutch thiab kho lub cav ceev kom hloov cov iav du.

Los yog tsawg kawg yog lub tswv yim, vim hais tias nyob rau hauv kev xyaum no automated phau ntawv yuav siv sij hawm ib pliag kom disengage lub clutch, hloov iav thiab reengage, ua rau lawv jerky thiab annoying, zoo li ib tug kawm tsav tsheb los yog ib tug kangaroo nkaum hauv qab koj hood. .

Lawv feem ntau tau hloov pauv thiab yuav tsum zam thaum yuav siv.

BMW SMG (kev sib txuas lus sib txuas lus) yog ib tug pioneer nyob rau hauv daim teb no, tab sis thaum lub technical executives hlub nws, ntau tus neeg tau tsav chim vim nws ineptitude.

Qee lub tsheb tseem tawm tsam nrog tib lub clutch, xws li Fiat's Dulogic kis tau tus mob, tab sis lawv feem ntau tau hloov thiab yuav tsum zam thaum yuav tsheb siv.

Dual Clutch kis tau tus mob (DCT)

Lub kaw lus dual clutch suab zoo li nws yuav tsum yog ob zaug zoo, thiab nws yog.

Cov gearboxes siab heev, tej zaum feem ntau siv los ntawm Volkswagen nrog nws cov DSG (Direkt-Schalt-Getriebe lossis Direct Shift Gearbox), siv ob lub zog sib cais, txhua tus nrog nws tus kheej clutch.

Lub tsheb niaj hnub muaj txiaj ntsig nrog DCT tuaj yeem hloov lub zog hauv milliseconds xwb.

Hauv xya qhov kev sib kis ceev, 1-3-5-7 yuav nyob ntawm ib qhov txuas thiab 2-4-6 ntawm lwm qhov. Qhov no txhais tau hais tias yog tias koj tab tom nrawm rau hauv peb lub iav, plaub lub iav yuav raug xaiv, yog li thaum nws yog lub sijhawm hloov, lub khoos phis tawj tsuas tso tawm ib lub clutch thiab koom nrog lwm tus, ua rau yuav luag ua haujlwm. Lub tsheb niaj hnub muaj txiaj ntsig nrog DCT tuaj yeem hloov lub zog hauv milliseconds xwb.

Lub tshuab VW yog ceev, tab sis ob-clutch gearboxes siv nyob rau hauv lub tsheb zoo li Nissan GT-R, McLaren 650S thiab Ferrari 488 GTB muab staggeringly ceev hloov sij hawm thiab yuav luag tsis muaj torque poob nyob rau hauv nruab nrab.

Raws li nyuaj raws li nws yog rau cov purist nqos, nws kuj ua rau lawv sai thiab yooj yim rau kev tswj dua li tej phau ntawv.

Tsis tu ncua Variable Transmission (CVT)

Qhov no yuav zoo li qhov kev daws teeb meem zoo tshaj plaws, tab sis CVT tuaj yeem cuam tshuam rau qee tus neeg.

CVT ua raws nraim li nws hais ntawm daim ntawv lo. Hloov chaw ntawm kev hloov pauv ntawm tus naj npawb ntawm cov phiaj xwm ua ntej, CVT tuaj yeem hloov cov iav piv ntawm ya yuav luag tsis tas li.

Xav txog cov tsheb thauj neeg lub khob ntim rau ntawm lub qag, nrog rau lub qag khoob thib ob uas sib npaug rau thawj. Tam sim no muab lub elastic rau ntawm lub qag thiab lub khob hliav qab.

CVTs tuaj yeem ua kom lub cav khiav ntawm qhov ua tau zoo tshaj plaws

Yog tias koj txav cov roj hmab band nce thiab nqis ntawm lub khob hliav qab, koj yuav hloov ntau npaum li cas lub qag khoob yuav tsum tig kom tiav ib qho kev sib hloov ntawm lub khob hliav qab. Los ntawm kev txav lub bar nce thiab nqis, koj hloov lub iav piv.

Txij li cov iav piv tuaj yeem hloov pauv yam tsis hloov lub zog, CVTs tuaj yeem ua kom lub cav khiav ntawm qhov ua tau zoo.

Hauv kev xyaum, qhov no txhais tau hais tias thaum koj nrawm hauv lub tsheb nrog CVT, nws ua rau lub suab nrov tsis tu ncua es tsis txhob siv cov tsoos nce thiab nqis.

Nws yog kev lag luam heev, tab sis tsis suab zoo li lub cav yuav tsum. Ib zaug ntxiv, qhov no yog kev xav purist thiab qee tus neeg tsis pom qhov txawv ntawm txhua qhov uas tsis yog lub twj tso kua roj.

Yog li dab tsi los xaiv?

Niaj hnub nimno automatics muab kev lag luam roj zoo dua li phau ntawv qhia vim qhov kev xaiv ntau dua ntawm cov iav piv. Feem ntau phau ntawv kis tau tus mob muaj rau lub zog rau pem hauv ntej, txawm hais tias Porsche 911 muaj xya.

Niaj hnub nimno dual-clutch systems siv xya lub zog, torque converter tsheb mus txog rau cuaj, thiab CVTs tuaj yeem tsim ib qho yuav luag tsis muaj qhov kawg ntawm cov iav piv, txhais tau tias lawv muab cov roj zoo tshaj plaws.

Nrog rau kev hloov ceev uas tsis meej pem tus tsav tsheb ceev tshaj plaws, qhov tsis siv neeg tuaj yeem ua kom nrawm dua.

Nws tsis yog ultra-ceev dual-clutch systems; ZF's cuaj-ceev torque converter kis tau tus mob muaj kev hloov pauv uas tau hais tias yog "hauv qab qhov pib ntawm kev nkag siab".

Ntau tus kws tsim khoom siv hluav taws xob tau txav deb ntawm kev sib kis ntawm phau ntawv nkaus xwb.

Nws zoo li kab hlau rhuav rau kev coj noj coj ua; uas tau dhau los ua qeeb, nqhis dej, thiab sab laug-ko taw-kev xaiv.

Ntau tus automakers yog ditching phau ntawv kis tau tus mob nkaus, yog li nws tsis yog ib qho qauv kev xaiv kom txuag tau ob peb bucks.

Nws nyuaj rau ntseeg, tab sis kev tsav tsheb sib kis tau zoo yuav zoo li absurdly retro rau koj cov xeeb ntxwv raws li cov ntaub ntawv yas niaj hnub no.

Dab tsi yog qhov koj nyiam kis tau tus mob? Puas yog koj tseem tsav tsheb tus kws kho tsheb? Qhia peb seb koj xav li cas hauv cov lus hauv qab no.
