CVT: Yuav ua li cas yog nws? Cia peb kawm

Muaj ib txhis tus naj npawb ntawm pub hom thaum lub tsheb yog tsiv. optimum engine kev kawm muaj peev xwm yuav ensured tsuas yog hais tias tus naj npawb ntawm cov theem nyob rau hauv lub gearbox kuj yuav infinite. Nyob rau hauv cov ntaub ntawv no nws yog tsim nyog los siv ib CVT. Yuav ua li cas yog nws? Nws yog tsuas yog nyob rau lub caij hom gearbox, uas tso cai rau stepless transformation ntawm lub iav piv nyob nruab nrab ntawm lub cav thiab kis tau tus mob. Qhov no txhais tau tias txhua txhua lub tsheb lag luam yuav ua hauj lwm nrog rau feem ntau zoo nqi ntawm cov iav ratio, es tshaj qhov nruab nrab, nyob rau hauv lwm yam embodiments ntawm transmissions.

CVT: Yuav ua li cas yog nws?

Nrog tas mus li lag luam ntawm lub engine dua efficiency yog tiav nyob rau hauv lub cheeb tsam ntawm pom revolutions, ntau zoo puab lub lag luam, yuav txo tau ntawm tshuaj lom emissions. Ntawm no yog lub iav piv yog hloov ntseeg nkaws es tsis txhob ntawm stepwise, li ntawd, hais tias xws li cov tsheb yog yus smoothness. Cov kev pab cuam lub neej ntawm cov kis Cheebtsam yog nce vim lub tsis tuaj kawm ntawv ntawm jerks thaum lub sij hawm iav hloov, nws yog ib qhov thiab yog tsiag ntawv los ntawm variator. Yuav ua li cas nws yog ib thiab yog dab tsi rau? Qhov no sib ntaus, yooj yim qauv, thiab txaus ntseeg tau. Raws li automatic transmissions, nws yog tsim los rhuav tshem ntawm cov neeg tsav tsheb los ntawm muaj hauj lwm ceev.

shortcomings

Tam sim no hais tias nws yog ib qhov tseeb yog dab tsi yog ib qhov zoo variator (nws yog dab tsi, koj twb paub), cov nqe lus nug tshwm sim raws li seb qhov no yog qhov zoo tagnrho gearbox. Tsis Lub ntsiab disadvantage ntawm qhov kev xaiv no yog tias nws yog tus txhuam uas yog tsis ua hauj lwm vim lub gearing, thiab vim kev sib txhuam, ces yog tau mus rau kis ib tug tsawg torque. Thaum nws tshaj cov ua hauj lwm tej chaw uas yuav npleem, ua rau ib tug intensive coj. Nws hais txog cov impossibility ntawm nws siv nyob rau hauv nrog ib tug haib engine.

CVT tsis tso ntev ua hauj lwm nyob rau hauv lub hom ntawm ntau load. Nws sai sai hnav tawm ntawm ntse jerks thiab braking cov yam ntxwv ntawm haib heev kev tsav tsheb style. Lub ntsiab ntawm qhov kev xaiv no - ib tug tus nyob ntsiag to lub zog.

Yuav ua li cas yog nws txoj ntsiab cai ntawm kev txiav txim?

Thaum lub caij, ob hom tsheb siv: torus thiab V-siv. Qhov thib ob muaj ib tug khub ntawm zawv zawg Pulleys ntawm uas tus siv yog tensioned. Ib tug ntawm cov Pulleys yog kev cob cog rua rau lub cav, li cov hlau lead, thiab lub thib ob nrog log - uas tau tsav. Pulleys zawv zawg, uas yog tsim los ntawm cov halves. Thaum lawv tuaj ua ke, muaj yog ib tug siv thawb tawm sab nraud, thiab thaum razdvizheniya siv tsis. Lub radii uas siv xyaum, cov kev hloov synchronously. Cov tshwm sim ntawm no yog ib tug tus hloov dua siab tshiab ntawm qhov kis tau tus mob piv yog hais tias tus tsav pulley voos kheej-kheej yog tsawg tshaj li tus qhev, ces tus hloov lwm lub tsev yuav raug muab txo, txwv tsis pub - ntau zog.

Dua CVT yuav siv cov conical disks es tsis txhob ntawm zawv zawg Pulleys thiab txoj siv tawv los hloov chais. Tsav phaj ua ke mus rau lub engine crankshaft, thiab tus qhev - cov kis. Lub chais yog pressed tiv thaiv cov discs thiab kis torque. Kho thiab CVTs nyob rau hauv lwm tus neeg mob yuav hloov lov qhov chaw nrog sawv daws yuav tshiab.
