Kis CVT - yog dab tsi? Automotive kis tau tus mob - CVT

Cia li txaus kom muaj ib lub tsheb, nws yog ib qho tseem ceeb kuj yuav to taub hais tias nws thiab yuav ua li cas nws ua hauj lwm. Lawm, tsis muaj ib tug tsis yuav tsum tau ib tug zoo tsav tsheb meej kev txawj ntse ntawm lub hauv paus ntsiab lus hauv cov combustion engine, tab sis tsawg kawg qhov yooj yim tej yam uas koj yuav tsum to taub hais tias kho lub tsheb yog tias tsim nyog. Tu siab, muaj breakdowns. Thiab tam sim no peb yuav tsom rau ib lub caij tseem ceeb. Kis CVT - yog dab tsi? Nws yog nyob rau no lub npe thiab peb mam li tham ntxiv.

kis tau tus mob

Nws yog nrog cov ntsiab cai thiab yuav tsum tau pib. Thawj thiab foremost koj yuav tsum to taub li cas no ntaus ntawv raws li ib tug tag nrho. Thiab ces yuav tau xav rau ntawm lub npe ntawm yuav ua li cas los txua lub CVT gearbox, nws yog dab tsi, thiab hais txog. D.

Yog li, kis tau tus mob - ib tug yuav tsum tau caij lub tsheb. Qhov tseeb yog tias tsis muaj nws, tag nrho cov ua hauj lwm ntawm ib tug complex combustion mechanism mus awry. Cov hauj lwm ntawm cov kis yog mus rau kis torque los ntawm lub engine rau cov log tsheb. Ua tau, nws kuj ua rau yus lub tsheb nyob rau hauv tsab ntawv tsa suab. Yog li ntawd, raws li koj tau pom, nws tseem ceeb yog ib qhov nyuaj rau overestimate.

Nyob rau hauv tas li ntawd, muaj lwm yam kev khiav dej num, xws li hloov tus traction, ceev thiab zuag qhia tag nrho cov kev taw qhia. Kis muaj tag nrho constellation ntawm ntau qhov chaw. Nyob rau hauv cov ntaub ntawv no peb xav xwb nyob rau hauv lub gearbox. Tab sis rau nws nws yuav yog ib lub me ntsis qis.

Nyob rau hauv tas li ntawd, koj kuj yuav tsum paub tias lub tsheb yog feem ntau yog siv electro-mechanical, thiab tej zaum kuj phau ntawv kis. Thaum kawg, qhov no yog qhov teeb meem no hnub no.

Kis - dab tsi nws yog

Yuav ua li cas koj yuav tsum to taub yog qhov tseeb hais tias xws li ib tug system yog cov yam ntxwv tsuas yog rau cov tsheb nrog nrog combustion xyaw. Nyob rau hauv lwm yam mob, xws li tej kev hluav taws xob tsheb, tsis muaj leverage yuav tsis tau. Cia li vim hais tias muaj yog tsis muaj tej kev xav tau.

Ua hauj lwm gearbox nws tus kheej yog raws li nram no: lub engine, uas yog siv nyob rau hauv tsheb, muaj ib tug heev ntau yam ntawm torque. Log, nyob rau hauv lem, yuav tsis tig nyob rau tib lub ceev. Cov kev siv theem kis tau tus mob no tso cai rau ib tug sib txawv nyob rau hauv ceev. KP kuj yuav pab kom cov neeg tsav tsheb tswj cov kev ceev ntawm kev sib hloov, acceleration thiab tseg cia nyob rau hauv lub sij hawm.

Los ntawm tej yam uas lwm tus neeg hais tias: hnub no thov cov neeg kho tshuab gearbox, manually ua, tsis siv neeg thiab nce mus nce los ceev. Tias lawv yuav nyob.

Los ntawm txhais tes gearbox

Tshwj xeeb tshaj yog yuav tsis tau nyob rau hauv no, tab sis tej yam uas tseem muaj nqis hais. Piv txwv li, lub operating hauv paus ntsiab lus. Yog li ntawd, nws yog nyob rau hauv lub complex mechanism ntawm shafts thiab zog. Nws yog lawv thiab tus neeg tsav tsheb ua hauj lwm los ntawm hloov lub kis tau tus mob qib, tsuas kho mechanism rau qhov tseeb lag luam rau nws. Tag nrho ob peb ua ke ntawm mechanisms txawv los ntawm ib lwm iav ratio, los ntawm uas yuav nyob ntawm seb cov kev ceev, uas sib sau tag nrho cov tshuab raws li ib tug tag nrho.

Nyob rau hauv Feem ntau, yuav luag txhua lub tsheb, uas muaj peev xwm yuav pom nyob rau hauv lub nroog, Txawm hais tias ib tug mechanical, es ib tug tsis siv gearbox lub CVT, lub tsuas yog peb-txoj kev. Qhov no txhais tau tias lub hom yuav muaj tsib los sis rau. Qhov ntawd yog plaub, thiab tejzaum nws tsib speeds tsav rau pem hauv ntej thiab rov qab rau hauv lub ceev kom hloov cov kev taw qhia. Nyob rau hauv no txoj kev, thiab nws tsim tau ib tug 5-ceev gearbox.

Tej zaum tuaj nyob piv txwv ntawm ib tug plaub-txoj kev lub thawv, thiab hais tias muaj lub thib rau, thiab txawm xya iav.

Qhov no yuav tsum tau hu ua ib tug meej overkill rau ib lub nroog tsheb. Yog hais tias peb tham txog cov ntau lug nyob rau hauv lub neeg nrog caij tsheb lawv yuav tsis siv.

Tsis Siv Neeg kis tau tus mob

Technically, tej kis tau tus mob uas yog tau mus ua hauj lwm ntawm nws tus kheej, tsis muaj kev koom tes ntawm cov neeg tsav tsheb, uas yog, ncav qhov kev kawm ceev, tsuas yog hloov lub ua ke ntawm shafts, yog suav tias yog tsis siv neeg. Tab sis nyob rau hauv qhov tseeb, nws feem ntau yog raug xa mus rau xwb planetary hydro system. Lawv yog cov feem ntau ntau, thiab nws yog yuav luag ib txwm hais txog lawv. Xav txog lwm cov kev xaiv vim hais tias nws yog tsis tsim nyog.

Yog hais tias muaj nqis mentioning txog electro thiab electro-mechanical pab kiag li lawm. Lub fact tias tag nrho cov ua hauj lwm nyob rau hauv lub electronics, ces muaj yog ib tug tej yam ib theem zuj zus ntawm kev ua "sewn" mus rau hauv lub heev phau ntawv no.

Txawm li cas los, tus neeg tsav tsheb yog tsis tau kiag li cais los ntawm cov txheej txheem - nws yog tsim nyog rau kev ruaj ntseg. Yog li ntawd, tus txiv neej qab lub log yuav xaiv cov hom kev lag luam los ntawm lub tsheb. Ua tau, nws yog los ntawm no nam nyob ntawm yuav ua li cas sai sai qhov kev hloov iav thiab yog dab tsi ceev tsis pub tshaj nce.

Yuav kom tswj cov chaw feem ntau siv pa zog. Txawm li cas los, nws lub hom phiaj hloov lub sij hawm, tab sis kom ntau tsav tsheb tsuas paub. Txawm li cas los, muaj ib co qauv ntawm cov tshuab, qhov twg cov nyees khawm yog siv. Nyob rau niaj hnub lub tsheb no feem ntau yog tau mus ntsib ib tug tag nrho cov numeric keypad, uas yog, nyob rau hauv qhov tseeb, ntawm lwm yam uas lub system.

CVT

Kis, kis tau tus mob - tag nrho cov no, ntawm chav kawm, yog ib qho tseem ceeb cov lus qhia. Tab sis tam sim no koj yuav tsum tau tuaj mus rau lub ntsiab ntsiab lus ntawm kev sib tham. Uas yog variativnoj gearbox. Ua tau, nyob rau hauv no thiab tag nrho cov xim yuav tsum teem.

CVT, los yog Tujtaws kuj tsis paub meej Kis, - precisely vim hais tias qhov no tsiaj ntawv stands rau. Lub peculiarity ntawm no kis tau tus mob yog hais tias nws yog muaj peev xwm mus hloov cov kev ceev ntau ntseeg nkaws. Yog li ntawd nws yog tau kom tsis txhob cia li jerks, uas yog cov yam ntxwv ntawm cov neeg kho tshuab thiab txawm mos ub - rau tsis siv neeg kis tau tus mob.

Qhov zoo ntawm cov xws li ib tug system ntau ntau. Tab sis nws yuav tsum tau muab sau tseg rau hauv lub tseem ceeb tshaj plaws ntawm lawv - lub peev xwm los siv cov torque ntawm lub cav ceev nrog lub siab tshaj plaws tau efficiency. Txhua yam yog vim cov hauj lwm ua ke ua hauj lwm ntawm lub engine Cheebtsam. Nyob rau hauv tas li ntawd, cov roj economy thaum uas siv cov xws li ib tug ntaus ntawv yog heev siab heev, thiab yog li caij - ib tug Library.

Niaj hnub no lawv yog siv heev dua lwm yam rau cov neeg nrog caij tsheb. Qhov tseeb hais tias technically lawv yog cov heev complex, vim hais tias mus ua lawv loj txaus thiab muaj hwj chim rau tib lub tsheb laij los yog tso tsheb hlau luam - ua hauj lwm exigeant. Dhau li lawv lub hom phiaj - mus ua lub neej yooj yim dua rau tus neeg zoo tib, thiab lawv tau paub mus ncig teb chaws mus rau lub ntsiab saloon thiab hatchback.

Qauv thiab muaj nuj nqi ntawm lub variator

Kis CVT - yog dab tsi? Yuav kom to taub, peb yuav tsum xub to taub nws cov ntaus ntawv. Nyob rau hauv Feem ntau, nws yog ib tug heev complex mechanism, uas twb tau hais ua ntej lawm. Tab sis mus piav qhia txog cov kev qauv li sai tau.

Yog li, ib tug tseem ceeb qhov chaw yog nyob los ntawm ib tug ntaus ntawv uas muab simultaneous kis tau tus mob rau engine ceev thiab disconnect nws los ntawm lub thawv. Siv mus ua hauj lwm nyob rau hauv ib tug nruab nrab txoj hauj lwm. Variator nws tus kheej raws li xws li yog siv rau kev tsav tsheb thaum twg ceev. Ib tug cais mechanism yog tshuaj rov qab - lub fact tias cov CVT yog tsuas yog tsis tau muab lub heev zog nyob rau hauv no cov kev taw qhia. Yog li ntawd nws yog tsim nyog los qiv uas nyob rau hauv tsis siv neeg transmissions.

Devices uas yog siv yuav txawv. Tam sim no nws yog tus thawj nyob rau hauv daim ntawv, uas yog, cov kev hloov ntawm lub zog. Piv txwv li, feem ntau yog ib tug torque converter. Ntxiv mus, muaj cov centrifugal thiab electromagnetic clutch, thiab nyob rau hauv tas li ntawd - multidisk "ntub."

variants ntawm lub variator

Qhov no tautology yog heev tsim nyog. Lub fact tias cov creation ntawm lub CVT mechanism yuav siv tau ib tug me ntsis txawv los ntawm lwm yam, uas cuam tshuam rau lub lag luam.

Piv txwv li, qhov uas pheej yig thiab heev - ib tug V-siv nce mus nce los ceev. Nws yuav siv ib qho siv tsav, tsim los ntawm ob tug conical disks. kawg zog muaj feem xyuam rau lub zuag qhia tag nrho lub cheeb thiab tswj los ntawm ib tug hydraulic mechanism.

Koj cov menyuam roj hmab tau ntev dhau mus rau hauv oblivion, tsuas yog vim nws fragility. Nrog ib tug ua hauj lwm pab rau tag nrho cov ntawm tsib caug txhiab kilometers thiab es cov neeg pluag yooj, tsis muaj dab tsi ceeb nyob rau hauv no. Lawv hloov los ntawm nws yog xim hlau koj cov menyuam ntawm ob peb ib daim hlab ntawm hlau. Tag nrho cov teeb meem ntawm yav dhau los versions tau lawm.

Yog lwm tau txoj kev ua hauj lwm - hlau saw. Yooj Yim yog superior rau tag nrho cov hom ntawm cov miv nyuas. Rau tag nrho cov mem tes kis siv tib lub high-zoo thiab check heev steel cones. Tag nrho cov no yog tsim nyog los ua rau kom cov kev pab cuam lub neej. Vim qhov no yog ib tug ncaj niaj hnub tsim, nws tsis yog li ntawd nws supplants tag nrho cov counterparts los ntawm kev ua lag luam. Ntawm no yog lub loj tshaj efficiency thiab cov losses xam qhovkev nyob rau hauv lub torque kis tau tus mob, yog tsis tshua.

CVT (Kis). cons

Zoo li lwm yam kev ntaus ntawv, nws tsis yog tiv thaiv kab mob los ntawm cov drawbacks. Lawv tsuas pab txhawb cov kev pab cuam uas coj qhov ua kom ntawm no mechanism.

Firstly, reseeding rau ib lub tsheb nrog xws li ib tug gearbox es tsis txhob ntawm lub niaj zaus koj yuav ua tau ntev txaus los mus xav tias ib txhia tsis xis. Qhov tseeb hais tias cov kev ceev tej zaum yuav txawv nyob rau hauv ib ntau yam. Qhov no yog tshwj xeeb tshaj yog muaj tseeb thaum lub tsheb accelerating. Tab sis qhov no drawback yog offset los ntawm qhov tseeb hais tias lub chaw ua hauj lwm nws tus kheej yog ntau tus. Raws li twb tau hais ua ntej, yog tsis muaj jerks thiab lwm yam "yeej ntawm lub neej" nyob rau phem txoj kev.

Koj muaj peev xwm kuj pabneeg ib cov tswv yim piv txwv ntawm ib tug zoo-paub lub tsheb manufacturers. Piv txwv li, kis tau tus mob CVT Nissan. Ib tug ntawm cov qauv, "Altima" 2013 tso tawm, nruab nrog xws li ib tug system. Yog li ntawd, cov neeg tsav tsheb tsis txaus siab txog cov tsis muaj rhiab heev yog heev tseem ceeb. Txawm li cas los, tsis yog txhua txhua paub tias nws, nws yog tsim nyog tshwj xeeb mention. Raws li lub taub hau ntawm lub tuam txhab hais tias, hais tias xws li pab kiag li lawm yog ib tug zoo lwm txoj rau automation, tab sis kuj nyob rau hauv tas li ntawd mus rau lub uas tsis muaj roj noj thiab nyoog emissions.

Nws yuav tsum coj mus rau hauv tus account lub fact tias tsis yog txhua tus CVT yog tau tiv nrog lub towing. Nyob rau hauv tas li ntawd, tag nrho cov unreliability ntawm lub qub qauv ntawm xav damped lub koob npe nrov ntawm tag nrho cov system. Tab sis tej teeb meem no feem ntau solved rau hnub tim. Yam tsawg kawg nyob rau hauv cov nqe lus ntawm durability.

purchase

Lwm interesting taw tes - tus nqi ntawm lub gearbox. Tus taw tes ntawm no yog hais tias cov variator yuav tsum yuav nkaus - ib zaug nrog cov kis tau tus mob. Txwv tsis pub, tsis muaj kev txiav txim zoo ntawm xws li ib tug purchase yuav tsis tau yooj yim. Thiab ntawm no thiab muaj cov tib teeb meem, vim hais tias cov teeb meem nqi yog heev, heev. Kis - ib tug tseem ceeb ib feem ntawm lub tsheb, ces koj yuav cawm tsis tau nws.

Tsuas yog tus purchase nws tus kheej muaj peev xwm ua rau ib tug tag nrho ntawm ntau tshaj 200 txhiab rubles. Feem ntau, txawm tias ib tug ntau heev. Thiab qhov no tsis muaj xws li installation, dua kev soj ntsuam, thiab hais txog. D.

Txawm li cas los, mus nrhiav tau xws li cov ntsiab nws yog heev sai tau. Rau lub hom phiaj no muaj ob lub ntsiab txoj kev. Tus thawj - yog hu rau lub chaw muab kev pab los yog cov khw muag cov ceg nyob rau hauv koj lub zos (nws yuav qhia qhov chaw yuav qhov chaw rau lawv lub tsheb), tsev loj qhov chaw los yog sim ua txhua yam li koj tus kheej. Uas yog yuav nrog nws. Txawm li cas los, nyob rau hauv lub caij nyoog kawg no cov ntaub ntawv, tsis muaj ib tug yuav lees tias koj muaj kev ruaj ntseg ntawm koj lub peev.

Raws li rau installation, zoo npaum li cas yog hais tias nws yuav tsum nqa tawm los ntawm cov kws tshwj xeeb. Tsis muaj txaus nyob rau hauv kev soj ntsuam nrog zoo xws li cov mechanisms, ib qho yooj yim rau hau ntswj li. Thiab muab tus nqi siv, nws yog tsis heev tsim nyog.

Kho ntawm automatic transmissions

Cov tom ntej no taw tes tseem ceeb ntawm lub hom phiaj - yog mus kawm kom saib xyuas ntawm lawv tus kheej "nqos". Ua tau hu ua CVT automatic kis tau tus mob yog tsis nkaus muaj tseeb, vim hais tias cov kis tau tus mob raws li xws li muaj tsuas yog tsis muaj. Tab sis nyob rau hauv kev nws tsis yog li ntawd ib qho tseem ceeb.

Cov feem ntau yooj yim yog ib feem ntawm tus tsim - txoj siv tawv. Ua tau, feem ntau ntawm cov tsis siv neeg kis tau tus mob kho cov lus dag nyob rau hauv nws hloov. Qhov teeb meem no yog hais tias nrov hnub no, steel saw yog heev tau puas txawm lub khob hliav qab hwj, tsis hais txog ntawm lawv lub zog. Tab sis nws muaj peev xwm twb ua rau mob loj heev txim.

Koj yuav tsum tau saib rau cov kev ceev sensor. Lub preset tsis yog tshwj xeeb robust, feem ntau tsis. Piv txwv li, nyob so ntawm txoj siv tawv, nws tsuas tsis tau lawm, txawm tias tus kis tau tus mob translates rau hauv thaum muaj xwm ceev hom. Cov yav tas, li cas los xij, yog tsis yog txhua txhua-haib, thiab tseem yuav cawm tsis tau koj los ntawm lub txim. Incidentally, lub roj hloov nyob rau hauv cov thawv tsuas yog nyob rau tshwj xeeb noj. Ib tug neeg txawj mechanics uas paub ntau yam txog kev pab cuam stepless variator nyob rau hauv Russia yog heev me me. Yog li ntawd, txawm xws li ib tug yooj yim txheej txheem raws li ib tug kev hloov rau roj, nws ua heev problematic rau lub tsheb tswv.

xaus

Ua tau, uas yog tag nrho cov koj yuav tsum paub txog cov variator. Yog li ntawd tam sim no koj tsis muaj yuav tsum tau teev nyob rau hauv xws li ib tug yooj yim lo lus nug: "Kis CVT - yog dab tsi?" Nws yuav tsum tau muab sau tseg hais tias qhov no ntaus ntawv yog capricious. Nws yog zoo li ib lo lus yuav piav txog nws. Khov rau sis tsis ncaj txoj kev, tshwj xeeb tshaj yog nyob rau hauv unpaved, ib co teeb meem nrog ib tug guarantee thiab tag nrho cov kev ntseeg - tag nrho cov no tsis txhawb npaum li cas cog qoob loo. Yog li ntawd, nws yog tsis zoo li mus rau tiv nrog cov kev sib tw nyob rau hauv Lavxias teb sab kev ua lag luam.

Cuaj kaum Kis CVT (CVT) yog heev haum rau kev siv. Nyob rau hauv ib co txoj kev uas nws yog txawm superior rau nws cov counterparts. Albeit no gearbox thiab tau tsav mus tsis zoo tag nrho, nws yog tseem tsim nyog ntawm cov xim.

Yog li ntawd, peb pom xws li ib tug kis tau tus mob ntaus ntawv raws li stepless variator.
