CVT

CVT gearbox (kapena CVT) ndi chipangizo chomwe chimatumiza mphamvu zozungulira (ma torque) kuchokera ku injini kupita ku mawilo, kutsitsa kapena kukulitsa liwiro la gudumu (chiwerengero cha zida) pa liwiro lomwelo la injini. Chinthu chosiyana ndi chosinthira ndikuti mutha kusintha magiya m'njira zitatu:

• pamanja;
• zokha;
• malinga ndi pulogalamu yoyambirira.

CVT gearbox ndi mosalekeza kusintha, ndiye kuti, si kusintha masitepe kuchokera giya wina, koma mwadongosolo kusintha chiŵerengero zida mmwamba kapena pansi. Mfundo yogwira ntchito imeneyi imatsimikizira kugwiritsa ntchito mphamvu kwa mphamvu yamagetsi, kumapangitsa kuti machitidwe asinthe ndikuwonjezera moyo wautumiki wa makina (zochitikira pa Favorit Motors Group of Companies service center zimatsimikizira izi)

Bokosi la variator ndi chipangizo chosavuta, chimakhala ndi zinthu zotsatirazi:

• chipangizo asynchronizing injini ndi gearbox (poyambira);
• mwachindunji siyana siyana;
• chipangizo choperekera kumbuyo (nthawi zambiri gearbox);
• magetsi olamulira;
• pompa hydro.

Pamagalimoto am'badwo waposachedwa, mitundu iwiri yamitundu yosiyanasiyana imagwiritsidwa ntchito kwambiri - V-belt ndi toroid.

Mbali za ntchito ya V-lamba CVT mabokosi

Bokosi la V-belt CVT ndi ma pulleys olumikizidwa ndi V-lamba wopangidwa ndi mphira wamphamvu kwambiri kapena chitsulo. Pulley iliyonse imapangidwa ndi ma discs awiri opangidwa mwapadera omwe amatha kusuntha ndikusintha makulidwe a pulley panthawi yoyenda, kuwonetsetsa kuti lambayo akuyenda movutikira kwambiri.

Mtundu wa V-lamba sungathe kupereka mowongoka (kuyendetsa mobwerera), popeza lamba amatha kuzungulira mbali imodzi. Kuti muchite izi, bokosi la V-lamba la V-lamba lili ndi zida zamagetsi. Bokosi la gear limatsimikizira kugawidwa kwa mphamvu m'njira yoti kusuntha kwa "kumbuyo" kumatheka. Ndipo gawo lowongolera zamagetsi limagwirizanitsa kukula kwa ma pulleys molingana ndi magwiridwe antchito amagetsi.

Mawonekedwe a ntchito ya toroidal CVT mabokosi

The toroidal variator mwadongosolo imakhala ndi ma shaft awiri okhala ndi mawonekedwe a toroidal. Mitsinje ndi coaxial ndi ulemu wina ndi mzake, ndi odzigudubuza ndi clamped pakati pawo. Pakugwira ntchito kwa bokosi, kuwonjezeka / kuchepa kwa chiŵerengero cha gear kumachitika chifukwa cha kusuntha kwa ma rollers okha, omwe amasintha malo chifukwa cha kayendedwe ka ma shafts. The torque imafalikira chifukwa cha mphamvu yothamanga yomwe imapezeka pakati pa ma shafts ndi ma rollers.

Komabe, ma gearbox a toroidal CVT sagwiritsidwa ntchito kawirikawiri m'makampani amakono amagalimoto, popeza alibe kudalirika kofanana ndi malamba amakono a V.

Ntchito zowongolera zamagetsi

Kuwongolera CVT, galimoto ili ndi dongosolo lamagetsi. Dongosolo limakupatsani mwayi wochita ntchito zingapo:

• kuwonjezeka / kuchepa kwa chiŵerengero cha magiya molingana ndi njira yogwiritsira ntchito mphamvu;
• Kuwongolera magwiridwe antchito a clutch (momwe wosinthira makokedwe nthawi zambiri amachita);
• dongosolo la magwiridwe antchito a gearbox (posintha).

Dalaivala amayendetsa CVT pogwiritsa ntchito lever (chosankha). Chofunika kwambiri cha kayendetsedwe kake ndi kofanana ndi magalimoto omwe ali ndi magalimoto odziwikiratu: muyenera kusankha ntchito (kuyendetsa kutsogolo, kuyendetsa kumbuyo, kuyimitsa galimoto, kuyendetsa galimoto, etc.).

Malangizo ogwiritsira ntchito ma variators

Akatswiri a Favorit Motors Group of Companies amawona kuti ma gearbox a CVT sali oyenera kunyamula katundu chifukwa chakuchulukirachulukira kwa injini. Komabe, kukula kwa ntchito yawo pa magalimoto okwera ali ndi tsogolo lowala, chifukwa kufala mosalekeza zosiyanasiyana ndi losavuta ndi yabwino ngati n'kotheka kwa madalaivala.

Pa nthawi yomweyo, palibe malangizo enieni eni magalimoto ndi CVT. Galimotoyo imamva bwino m'misewu yamzindawu komanso m'misewu, chifukwa kuchepa / kuwonjezeka kwa liwiro ndikosavuta momwe mungathere.

Komabe, monga momwe zimakhalira ndi mtundu uliwonse wa kufalitsa, zinthu ziwiri zidzakhudza moyo wa makinawo: kalembedwe kameneka komanso kusintha kwamadzimadzi panthawi yake. Panthawi imodzimodziyo, m'pofunika kutsindika zapadera za kukonza makina: ngati galimoto ikugwiritsidwa ntchito m'mizinda yokha, ndiye kuti kusintha kwa mafuta sikofunikira. Poyendetsa msewu, ndi ma trailer kapena pamsewu wothamanga kwambiri, opanga amalangiza kusintha mafuta pambuyo pa makilomita 70-80 zikwi.

Eni magalimoto ndi CVT (V-belt version) amadziwa kuti lamba ayenera kusinthidwa pambuyo makilomita 120 zikwi. Ngakhale ngati palibe zolakwika zowoneka panthawi yoyendetsa galimoto, muyenera kuganizira mozama ndondomekoyi, chifukwa kunyalanyaza kusintha lamba kungayambitse kuwonongeka kwa bokosi.

Ubwino wa mtunduwu pamitundu ina yotumizira

CVT imatengedwa kuti ndi mtundu "wapamwamba" wopatsirana. Pali zifukwa zingapo zochitira izi:

• kusuntha kosalala kwa chiŵerengero cha gear kumapereka mphamvu zabwinoko poyambira kapena kuthamanga;
• chuma cha kugwiritsa ntchito mafuta;
• kukwera kosalala komanso kosalala kwambiri;
• palibe kuchepa ngakhale pakukwera kwautali;
• kusamalidwa kosayenera (mapangidwewo ndi osavuta, ali ndi kulemera kochepa kuposa, mwachitsanzo, kufala kwachikale kokha).

Masiku ano, kuchuluka kwa opanga magalimoto akubweretsa ma CVT m'magalimoto. Mwachitsanzo, chomera cha Ford chili ndi chitukuko chake m'dera lino, kotero kuti mbadwo watsopano wa magalimoto umapangidwa ndi Ecotronic kapena Durashift CVT.

Kukhazikika kwa ntchito ya CVT ndikuti pakusintha chiŵerengero cha zida, phokoso la injini silimasintha, zomwe sizili zofanana ndi mitundu ina ya kufalitsa. Komabe, ena opanga mitundu yaposachedwa ya CVTs ayamba kugwiritsa ntchito zotsatira za kuchuluka kwa phokoso la injini malinga ndi kuchuluka kwa liwiro lagalimoto. Ndipotu, oyendetsa galimoto ambiri amazoloŵera kusintha phokoso la injini ndi mphamvu zowonjezera.

Mwiniwake aliyense wagalimoto amasankha galimoto malinga ndi zomwe amakonda, zosowa zake komanso luso lazachuma. Magalimoto okhala ndi CVT amadziwika ndi kudalirika komanso kuchuluka kwa kukana kuvala, koma matekinoloje atsopano ndi okwera mtengo kwambiri. Mutha kusankha mwachangu galimoto malinga ndi zomwe mukufuna komanso zomwe mungathe ngati mutasankha galimoto yoyenera. Favorit Motors Group of Companies imapereka mitundu yosiyanasiyana kuchokera kwa opanga osiyanasiyana pamitengo yotsika mtengo.

Only mbiri yabwino galimoto misonkhano akhoza kuchita diagnostics, kukonza ndi kusintha siyana. Paza akatswiri a Favorit Motors technical center pali zida zonse zofunikira zowunikira ndi kukonza, zomwe zimakuthandizani kuti muchepetse zovuta zakusintha kwanthawi yayitali mwachangu komanso kwakanthawi kochepa.

Ambuye odziwa bwino a Favorit Motors adzachita zowunikira zapamwamba zamitundu, kukhazikitsa zomwe zimayambitsa kusagwira ntchito ndikuzichotsa. Ndipo, kuwonjezera, iwo amalangiza olondola ntchito gearbox CVT. Njira yokonzanso ikuvomerezedwa ndi kasitomala, ndipo mtengo wokonzanso ndi kubwezeretsa ntchito umalengezedwa pambuyo pa matenda.
