Yuav ua li cas mus xaiv: CVT los yog tsis siv neeg?

Feem ntau cov neeg tsav tsheb tseem ua ntej mus yuav ib lub tsheb, twb txiav txim siab, los yog CVT automatic tuaj tos thiab tej zaum txawm xav mechanics. Tab sis tej zaum nyob rau hauv cov kev xaiv tseem muaj teeb meem. Nws yuav tsum tau saib mus rau hauv qhov teeb meem, uas gearbox yog zoo dua? Ceeb tshaj, lub CVT ntev los no nyob, vim hais tias ntawm cov uas nws ua hauj lwm zoo shortcomings tsis paub zoo. Txawm li cas los robotic stepless kis tau tus mob muaj ntau yam zoo.

Raws li qhov zoo ntawm ib tug tsis siv neeg kis tau tus mob yuav tsum tau hu ua ib tug txo cov roj noj, ib tus nqi pheej yig kis tau tus mob, uas tsis muaj nqi ntawm txij nkawm. Raws li drawbacks feem ntau emit tsawg ceev thiab du shifting.

Robotized kis tau tus mob yog pom tias yuav tau qhov zoo tshaj plaws tshuaj. Nws yog ntsia tau rau hauv lub BMW M-series. Nws yog raws li rau hauv lub rau-speed gearbox, uas txhais tau hais tias switching tawm lub hydraulics thiab lub clutch.

Raws li variator zoo cais smoothness thiab siab switching ceev, ib ntsis roj noj. Qhov tsis zoo yog xam tau tias yog nqi ntawm cov kis tau tus mob thiab tus nqi ntawm nws cov tom ntej txij nkawm.

Lub npov no yog ib tug tsis tu ncua nce mus nce los kis tau tus mob systems, uas nteg lub lub hauv paus rau ib tug heev yooj yim txoj ntsiab cai - torque hau hwj chim rau tus roj hmab siv tsim los ntawm lub conical log, uas ua rau nws tau mus ua ib lub pulley siv kis tau tus mob. Daws, los yog CVT automatic, nws yog ib qho tseem ceeb kom paub txog lub biggest shortcomings ntawm thawj - cov tsis muaj rov qab thiab nruab nrab iav. Qhov no yuav ua tau ib tug tseem ceeb chaw khuam siab rau ib co kev xaiv.

CVT: lag luam

Lub hauv paus nteg variator iav, cov nuj nqi uas yog ib tug compound ntawm lub log thiab lub engine. Nws yuav txawm peem rau thiab ua, uas muaj ib tug ntsia hlau thiab ib tug kab ntsig maum. Thaum ua hauj lwm nrog xws li ib tug tsav yog feem ntau tau ib tug du transformation ntawm tus tsav ceev raws li tus tswv thiab tus qhev. Txawv pab kiag li lawm tau ntev tau siv xws npaj.

Daws, los yog CVT automatic tuaj tos, yuav tsum tau paub txog cov pros thiab cons thawj. Cia tus thawj tham txog qhov zoo yam. Lub tsheb, nyob rau hauv uas ib tug variator tsiv ntseeg nkaws, uas tsis muaj tej laim, jumps. Nrog ua ceev tshwm heev me ntsis suab nrov, ua louder. Xws li ib tug lub tsheb yooj yim neeg ntaus ib tug haib tshuab, uas yog txuam nrog lub sij hawm-saving, uas feem ntau yog siv nyob rau hauv ceev selector. Thaum lifting ib lub tsheb tsis yob rov qab, thiab ntawm lub tsheb teeb nres.

Nyob rau hauv tag nrho cov tshwm sim, lub tsheb nrog ib tug CVT pib rau koj tsiv heev ntseeg nkaws, tsis overloading cov kis. Tsav lub feem ntau yooj yim, vim nws muaj tsuas yog ob tug pedals.

Nyob rau hauv cov tsheb lub cav suab yog heev tiaj tus, nrog ib qho kev nce nyob rau hauv ceev tsis tau hnov suab nrov dhau. Tag nrho cov no yog ua tau tsuas yog ua tsaug rau ib tug tshwj xeeb electronics, stabilizing lub load rau ntawm lub cav. Peb yuav hais tias ib lub tsheb nrog ib tug CVT muaj ib tug ntau ntawm cov zoo, cov tseem ceeb tshaj plaws ntawm no yog roj economy, raws li zoo raws li lub tseem yuam pib.

Txawm li cas los, qhov no kis tau tus mob tseem muaj disadvantages. Tsheb nrog peev xwm loj xyaw tsis txawm peem rau nrog variator. Kis yuav tsum tau sau nrog ib tug tshwj xeeb cov kua, thiab ces tsis haum rau ib tug uas twb tau merged nrog rau lwm cov PPC yog tso cai nyob rau hauv cov ntaub ntawv ntawm ib tug tsis siv neeg kis tau tus mob. variator lag luam yog tsis yooj yim sua yam uas tsis tau siv ib tug plurality ntawm sensors, xws li siab sensor, ceev thiab lwm tus neeg.

Nyob rau hauv Feem ntau, thaum txiav txim siab seb yog dab tsi xaiv, los yog CVT automatic, cia siab feem ntau ntawm seb koj puas kam mus nyob rau ib fundamentally tshiab ntsiab cai ntawm kev tswj lub tsheb.
