CVT kufala - ubwino ndi kuipa kwa gearbox ndi siyana mu galimoto

Kutumiza kwa CVT kuli ndi mayina osiyanasiyana amalonda, monga Multitronic ya mtundu wa Audi. Mosiyana ndi njira zodziwikiratu, kuchuluka kwa magiya pano ndi - theoretically - yopanda malire, chifukwa chake, palibe masitepe apakatikati (pali ochepera komanso apamwamba). Dziwani zambiri za kutumiza kwa CVT!

Kodi variator imagwira ntchito bwanji? Nchiyani chimapangitsa izo kuonekera?

Chifukwa cha CVT yopangidwa mwapadera, mphamvu yamagetsi yagalimoto imagwiritsidwa ntchito bwino. Ichi ndi chifukwa chakuti basi amasankha chiŵerengero cha zida kuti kukhalabe injini liwiro pa mlingo woyenera. Pakuyendetsa bwino, izi zitha kukhala 2000 rpm, koma pothamangitsa zitha kukwera mpaka pomwe injini imafikira makokedwe ake apamwamba. Dziwani kuti limagwirira ndi zabwino zonse mafuta ndi dizilo, ndipo ngakhale magalimoto hybrid.

Kupanga ndi kugwira ntchito kwa CVT kufala kosalekeza

Chimodzi mwazinthu zazikulu zomwe mapangidwe ndi magwiridwe antchito amtundu uliwonse wamakono wa CVT ndi zida za bevel (zotulutsa ndi zowawalira), zomwe zimatchedwa CVT. Mapangidwe ovuta amakhalanso ndi makina oyendetsa galimoto kupyolera mu lamba wolemera wachitsulo. Ndi unyolo wa maulalo mazana angapo. Amasankhidwa mwapadera kuti makulidwe, m'lifupi komanso ngakhale taper angle. Komabe, njira zamakono zamakono sizingagwire ntchito bwino popanda kutenga nawo mbali pamagetsi.

Chinthu chapakati chomwe chimasankha magawo omwe makina osasunthika agalimoto amagwira ntchito ndi gawo lapadera lowongolera. Imayang'ana malo a accelerator pedal komanso kuthamanga kwa galimoto komanso kuthamanga kosalekeza kwa unit drive. Pazifukwa izi, imayang'anira kusuntha kwa chosinthira posuntha mawilo a bevel pafupi kapena motalikirana. Chifukwa chake, amasintha momwe amagwirira ntchito motero amasintha chiŵerengero cha zida zomwe zimagwiritsidwa ntchito pano. Makinawa amagwira ntchito mofanana ndi derailleur yanjinga, koma pakadali pano, tilibe zoletsa za magiya apakatikati monga magiya.

Kugwiritsa ntchito ma transmissions mosalekeza pamagalimoto amakono.

Chifukwa cha magwiridwe antchito a variator, zida zamagetsi zokha Kupatsirana kosalekeza kumagwiritsidwa ntchito makamaka pamagalimoto amakono okhala ndi miyeso yaying'ono ndipo, molingana ndi kulemera kocheperako. Monga lamulo, ali ndi ma motors okhala ndi mphamvu zochepa komanso torque yotsika kwambiri. Chifukwa cha izi, malamba kapena maunyolo omwe amayendetsa galimotoyo sakhala ndi katundu wambiri, zomwe zimakulolani kupanga njira zodalirika zotumizira. Magalimoto okhala ndi makina a injini okhala ndi torque pafupifupi 200 Nm amaonedwa kuti ndi abwino kwambiri pano.

Kutumiza kwa CVT m'magalimoto a 4 × 4

Kutumiza kwatsopano kwa CVT kumapezekanso m'magalimoto akuluakulu a 4 × 4, monga momwe zimasonyezedwera ndi mitundu yopangidwa ndi mtundu wa Japan Mitsubishi. Akatswiri aluso amawapanga kuti akhale abwino kwa magalimoto olingana ndi kukula kwa magalimoto akuluakulu kapena magalimoto akuluakulu. Mayankho a kalasiyi amagwiritsidwanso ntchito pamagalimoto a mawilo awiri, mwachitsanzo. njinga zamoto. njinga yamoto yovundikira okonzeka ndi mtundu wa gearbox anaonekera pa msika mu 1938. 

Ubwino wa CVT

Ubwino waukulu wa kufala kwa CVT ndikutha kuchepetsa kugwiritsa ntchito mafuta. Mudzaona ndalama, makamaka ngati mutatsatira malamulo oyendetsa galimoto ndikuyembekezera zomwe zikuchitika pamsewu. Kumene, ntchito wamphamvu kwambiri accelerator pedal ndithu zimakhudza kumwa mafuta, mosasamala kanthu kuti galimoto ali ndi zodziwikiratu kapena kufala Buku. Ubwino wina ndikutha kuchepetsa ndalama zogwirira ntchito m'magalimoto omwe ali ndi injini zama torque, i.e. mu dizilo.

Phindu lotchulidwa nthawi zambiri lomwe mungazindikire mukayendetsa mozungulira tawuni ndikuyenda kosalala ndikusintha mwachangu mmbuyo ndi mtsogolo. 

Zoyipa za bokosi la variator 

The kuipa monga mokweza pang'ono ntchito ya stepless variator poyerekeza makina ochiritsira. Izi zimachitikanso chifukwa cha phokoso lochokera ku chipinda cha injini, chopangidwa ndi galimoto (ngakhale kuthamanga kwa kuyenda kumakhala pafupifupi kosalekeza). Madalaivala ambiri amalabadiranso pafupipafupi kulephera kwa gearbox, koma nthawi zambiri sichifukwa cha kapangidwe kake, koma chifukwa cha ntchito yolakwika ndi kukonza.

Kuwonongeka kofala kwa ma variable speed automatic transmission (e-CVT)

Chimodzi mwazolakwika zomwe zimafala kwambiri pamagetsi a CVT ndi kuvala lamba wagalimoto (kapena unyolo). Mawilo omwe amapanga dongosolo la CVT, lomwe ndi chinthu chofunikira kwambiri pakupatsirana kosalekeza kosalekeza, nawonso amatha kuvala pang'onopang'ono.

Kulephera kofulumira kumakhudzidwa makamaka ndi kugwiritsa ntchito kwambiri dongosolo, mwachitsanzo, kuyendetsa masewera olimbitsa thupi kapena kuthamanga kwambiri. Pazifukwa izi, galimoto yokhala ndi CVT sayenera kugwiritsidwa ntchito ngati njanji kapena mpikisano wamsewu. Ndikofunikanso kusintha mafuta a gear nthawi zonse, monga mafuta odzolanso amawonjezera mphamvu zotsutsana mkati mwa kufala kwadzidzidzi, ndipo, chifukwa chake, kuvala kwake mofulumira. Ndizofunikira kudziwa kuti zovuta zambiri zachotsedwa munjira zaposachedwa zolembedwa ndi e-CVT zomwe zimagwiritsidwa ntchito pamagalimoto osakanizidwa.

Mtengo wa ntchito ndi kukonza kwa variator

Kukwera mtengo kwa ntchito ndi kukonza Ma gearbox othamanga osinthika ndi amodzi mwa mikangano yodziwika bwino motsutsana ndi chisankho chamtunduwu. Kodi muyenera kuvomereza mfundo zawo? Osati kwenikweni, chifukwa nthawi zambiri mavuto amadza chifukwa cha ntchito yosayenera ya gawo kufala, ndipo nthawi yomweyo kukonza galimoto ndi makina unverified. Zotsatira za njirayi ndi ntchito zodula, zomwe zimagwirizanitsidwanso ndi mtengo waukulu wa zida zosinthira.

Dziwani kuti ma CVT awa nthawi zambiri amakhala olimba pang'ono poyerekeza ndi ma transmission wamba omwe amagwiritsidwa ntchito masiku ano. Mfuti zodziyendetsa zokha payekha. Komabe, amapereka ulendo wosavuta komanso wothamanga, ndipo nthawi yomweyo amadziŵika ndi mafuta otsika kwambiri pamene akusunga mfundo za "eco driving". Gawo lawo lofunikira ndi chowongolera chapadera chamagetsi, chomwe chingalephereke chifukwa cha chinyezi chomwe chimalowa m'dongosolo kapena ma surges amphamvu omwe amalumikizidwa ndi kulumikiza chowongolera kuti azilipiritsa batire.

Zothandiza komanso zogwira ntchito za CVT gearbox

Kulimbikitsidwa ndi amakanika ambiri odziwa zambiri komanso eni magalasi, kufalitsa kothandiza komanso kogwira ntchito kwa CVT ndi chisankho chabwino kwambiri kwa anthu ambiri. Ubwino wake udzayamikiridwa makamaka ndi ogwiritsa ntchito magalimoto, makamaka akuyendayenda mumzinda. Ndi kukonza koyenera, kufalitsa kosasintha kosinthika kumakhala ndi moyo wautali wautumiki komanso ntchito yopanda mavuto.
