Kodi Kusiyana ndi Chiyani Ndipo Kumagwira Ntchito Motani?
Mu dziko la magalimoto, zinthu zambiri zimagwira ntchito mogwirizana kuti zipereke magwiridwe antchito abwino, chitonthozo, komanso chitetezo kwa oyendetsa ndi okwera. Chinthu chimodzi chofunikira chomwe nthawi zambiri chimanyalanyazidwa ndi kusiyana. Nkhaniyi ifotokoza tanthauzo la kusiyana, momwe kumagwirira ntchito, komanso chifukwa chake kuli kofunikira kwambiri mu makina otumizira magalimoto a galimoto.
Kumvetsetsa Kusiyana
Mwachidule, chosiyanitsa ndi chinthu chomwe chimalola mawilo omwe ali pa axle imodzi kuzungulira pa liwiro losiyana. Izi ndizofunikira kwambiri makamaka pamene galimoto ikuzungulira. Popanda chosiyanitsa, mawilo amkati ndi akunja angazungulire pa liwiro lomwelo, zomwe zimapangitsa kuti matayala asamayende bwino, komanso kuti galimoto isayende bwino.
Mbiri Yosiyana
Kusiyana kumeneku si chinthu chatsopano; lingaliroli linayamba ku Roma wakale. Komabe, kugwiritsidwa ntchito kwake pa magalimoto amakono kunayamba m'zaka za m'ma 19 ndi injiniya wa ku France Onésiphore Pecqueur. Kapangidwe koyambirira aka kasintha kukhala kamakono komwe timakudziwa lero.
Mtundu Wosiyana
Pali mitundu yosiyanasiyana ya ma differentials omwe amagwiritsidwa ntchito m'magalimoto osiyanasiyana, kuphatikizapo:
1. Kusiyanitsa Kotseguka
Uwu ndiye mtundu wofala kwambiri wa ma differential. Mawilo mwachibadwa amakumana ndi liwiro losiyana ndi ma torque popanda kulowererapo kulikonse kuchokera ku dongosolo. Ngakhale kuti ndi othandiza komanso otsika mtengo, differential iyi ili ndi zovuta pamene gudumu limodzi litaya mphamvu.
2. Chosiyana Chotsekedwa
Kusiyana kumeneku kumalola mawilo onse awiri omwe ali pa ekseli imodzi kuzungulira pa liwiro lomwelo. Ngakhale kuti kumathandizira kuti matayala azigwira bwino ntchito, mtundu uwu ukhoza kupangitsa kuti matayala azigwira ntchito movutikira komanso kuti aziwonongeka kwambiri.
3. Kusiyanitsa Kochepa kwa Slip (LSD)
Cholinga cha LSD ndi kuthana ndi zovuta za differential yotseguka. Differential iyi imalola kusiyana kwa liwiro pakati pa mawilo awiriwa, koma ndi zoletsa zina kuti zisatayike kugwira ntchito pa gudumu limodzi.
4. Kusiyanitsa kwa Tork Vectorial (Kusiyanitsa kwa Torque Vectorial)
Uwu ndi ukadaulo wapamwamba womwe umagawa mphamvu ya galimoto ku gudumu lililonse. Dongosololi limagwiritsa ntchito masensa ndi ma actuator osiyanasiyana kuti liwongolere kugwira ntchito bwino kwa galimoto komanso kukhazikika, makamaka ikatembenuka movutikira kapena misewu yoterera.
Momwe Kusiyanitsa Kumagwirira Ntchito
Ngakhale zingamveke zovuta, mfundo yoyambira yogwiritsira ntchito differential ndi yosavuta. Nazi njira zoyambira za momwe differential imagwirira ntchito:
Kutumiza Mphamvu Kuchokera ku Injini
Injini ya galimoto imapanga mphamvu, yomwe imatumizidwa ku giya. Kuchokera ku giya, mphamvu imatumizidwa ku shaft yoyendetsera, yomwe imalumikizidwa ku differential.
Zida Anatipatsa
Mkati mwa chosiyanitsa muli sitima yamagetsi yokhala ndi giya ya pinion, giya ya ring, giya ya kangaude, ndi magiya am'mbali. Sitima yamagetsi iyi imagwira ntchito yogawa mphamvu kuchokera ku axle yoyendetsera kupita ku mawilo onse awiri.
Kusiyana kwa Liwiro la Mawilo
Galimoto ikamayenda molunjika, mawilo onse awiri amalandira mphamvu yofanana. Komabe, galimoto ikatembenuka, gudumu lakunja liyenera kuzungulira mofulumira kuposa gudumu lamkati. Apa ndi pomwe kusiyana kumabwera, zomwe zimapangitsa kuti liwiro lizisiyana popanda kutayika kwakukulu kwa mphamvu.
Kulamulira Kugwira Ntchito
Mu mitundu ina yosiyana, monga ma differentials ocheperako (LSDs) ndi ma torque vectoring systems, ma torque ena amawongolera kugawa kwa ma torque kuti akonze kugwirika kwa ma torque ndi kukhazikika kwa galimoto. Mwachitsanzo, mu LSD, gudumu limodzi likataya kugwirika kwa ma torque, makinawo amaletsa kusiyana kwa liwiro ndikutumiza ma torque ambiri ku gudumu ndi kugwirika kwabwino.
Ubwino ndi Kuipa kwa Kusiyana
Keuntungan
1. Kusinthasintha Kowonjezereka: Ma differential amalola kusiyana kwa liwiro pakati pa mawilo awiri pa ekseli imodzi, zomwe zimapangitsa kuti galimotoyo ikhale yosavuta kuzungulira.
2. Kugwira Bwino Kwambiri: Mitundu yamakono yosiyana monga LSD ndi torque vectoring imapereka mphamvu yogwira bwino kwambiri, makamaka pamsewu woterera kapena pamalo osafanana.
3. Kuchepa kwa Kuwonongeka kwa Matayala: Mwa kulola mawilo kuzungulira pa liwiro losiyana, kusiyana kumeneku kumathandiza kuchepetsa kuwonongeka kwa matayala kosagwirizana.
Kusowa
1. Kuvuta ndi Mtengo: Ma differentials, makamaka mitundu yapamwamba monga LSD ndi torque vectoring, ali ndi zovuta zambiri ndipo amatha kuwonjezera ndalama zosamalira ndi kukonza.
2. Zofooka za Kugwira Ntchito mu Ma Differential Otseguka: Ma differential otseguka ali ndi zofooka zazikulu pankhani ya kugwira ntchito, makamaka ngati gudumu limodzi lataya kugwira ntchito pamwamba.
3. Kugwiritsa Ntchito Mafuta: Machitidwe ovuta kwambiri monga torque vectoring differentials amatha kuwonjezera kugwiritsa ntchito mafuta chifukwa pali zinthu zambiri zosuntha zomwe zimafuna mphamvu.
Kusamalira Kosiyana
Ndikofunikira kusunga differential yanu bwino mwa kukonza nthawi zonse. Zina mwa zinthu zomwe mungachite ndi izi:
Kusintha kwa Mafuta Osiyanasiyana
Mafuta osiyanitsa ndi ofunikira popaka mafuta mkati mwa differential, kuchepetsa kukangana ndi kuwonongeka. Nthawi zambiri amalangizidwa kusintha mafuta osiyanitsa ndi ena makilomita 40,000 mpaka 60,000 aliwonse, koma izi zimatha kusiyana kutengera mtundu wa galimotoyo komanso momwe imagwirira ntchito.
Kuyang'ana Kachitidwe
Yendani nthawi zonse muone ngati pali zinthu zosiyanitsira magetsi, magiya owonongeka, kapena mavuto ena omwe angakhalepo. Kuwunika kumeneku kuyenera kuchitidwa ndi makanika waluso yemwe amadziwa bwino makina osiyanitsira magetsi.
Kuteteza Kutaya kwa Madzi
Kutuluka kwa madzi mu differential kungawononge zigawo zake mwa kupangitsa kuti mafuta asamayende bwino. Kuonetsetsa kuti ma seal ndi ma gasket omwe amagwiritsidwa ntchito mu differential system ali bwino ndi njira yofunika kwambiri yopewera.
Tsogolo Losiyana
Ukadaulo ukusintha nthawi zonse, ndipo kusiyana sikusiyana. Mu nthawi ya magalimoto amagetsi ndi odziyimira pawokha, kusiyana kukuchitikanso mwatsopano. Mwachitsanzo, magalimoto ena amagetsi amagwiritsa ntchito makina oyendetsa pawokha pa gudumu lililonse, zomwe zingachotse kufunikira kwa kusiyana kwachikhalidwe. Kuphatikiza apo, ukadaulo wa AI ndi makina ophunzirira akuyembekezeka kukulitsa kuthekera kwa kusiyana kwa torque ndi maulosi olondola komanso kusintha kwa nthawi yeniyeni.
Mapeto
Chosiyanitsa ndi chinthu chofunikira kwambiri pamakina a galimoto, zomwe zimathandiza kuti mawilo a pa ekseli imodzi azitha kusinthasintha, kusuntha bwino, komanso kukhala omasuka kuyendetsa. Ngakhale chili ndi zovuta zina, monga ndalama zambiri zokonzera magalimoto apamwamba, ubwino womwe ma differentials amapereka umawapangitsa kukhala chinthu chofunikira kwambiri, makamaka m'magalimoto amakono. Podziwa bwino momwe ma differentials amagwirira ntchito ndikusamalira magalimoto, magalimoto amatha kusamalidwa kuti agwire bwino ntchito m'misewu yosiyanasiyana.
