Magudumu a aloyi, omwe amadziwikanso kuti aluminiyamu alloy wheels, ndi mawilo agalimoto omwe amapangidwa makamaka kuchokera ku aluminiyamu alloy (kapena ma aloyi ena opepuka monga aluminiyamu-ma magnesium alloys) kudzera m'njira monga kusungunula, kufota ndi kupanga.
Poyerekeza ndi-mawilo onse achitsulo, mawilo a alloy ndi opepuka (akulemera 10–20% kuchepera), zomwe zimathandiza kuchepetsa kugwiritsa ntchito mafuta komanso kuwongolera kamvekedwe kake; Amaperekanso matenthedwe abwino kwambiri, kukana kwa dzimbiri komanso kusinthika kokongola, kuwapangitsa kuti azitha kuwononga mwachangu kutentha komwe kumapangidwa panthawi ya braking ndipo potero amachepetsa chiopsezo cha magudumu.
Zosiyanasiyana
Kutengera ndi momwe amapangira, mawilo a alloy amawagawa kukhala ma wheel (omwe ndi otsika mtengo komanso amagwiritsidwa ntchito kwambiri popanga zambiri) ndi mawilo opangira (omwe amapereka mphamvu zapamwamba komanso zopepuka zopepuka, ndipo amagwiritsidwa ntchito kwambiri-pamagalimoto oyenda bwino).
Mawilo opangira, makamaka, amapangidwa pogwiritsa ntchito mphamvu ya masauzande kapena masauzande a matani kuti akanikize mwachindunji ma ingots olimba a aluminiyamu kuti apange mawonekedwe, monga 'kupangira chitsulo'. Amadziwika ndi mphamvu zambiri, kulemera kopepuka, kuyendetsa bwino kwamafuta komanso kusamalira bwino. Komano, mawilo otayira amapangidwa ndi kutentha kwa aluminiyamu kumadzimadzi, kuwatsanulira mu nkhungu ndikulola kuti iziziziritsa ndikuyika. Njira imeneyi ndi yosavuta, yotsika mtengo-ndipo imalola kuti pakhale mapangidwe osiyanasiyana. Kusiyanitsa pakati pa awiriwa kumakhala makamaka pakupanga zinthu, zomwe zimapangitsa kusiyana kwakukulu kwa ntchito, kulemera ndi mtengo.
Kuyerekeza Kuyerekeza
| Dzina lazogulitsa | Mawilo opangidwa | Mawilo oponya |
| Kapangidwe kachitsulo | kapangidwe ka mamolekyulu owundikiza kwambiri, opanda porosity kapena looseness | ikhoza kukhala ndi pores, yokhala ndi mawonekedwe otayirira |
| Mphamvu ndi Kulimba | Kulimba kwakukulu kwambiri komanso kukana kukhudzidwa kwakukulu; komabe, alibe mphamvu-ndipo sangagwedezeke chifukwa cha ziwawa, amatha kusweka. | Mphamvu zolimbitsa thupi ndi kulimba kwabwino; amatha kupindika ndikupunduka paziwopsezo, potero amatenga mphamvu yamphamvu. |
| Kulemera | chopepuka; 15-20% yopepuka kuposa mawilo oponyedwa ofanana kukula | cholemera |
| Mapangidwe ndi Maonekedwe | Chifukwa cha kuchepa kwa njira zopangira, mapangidwe awo ndi osavuta, koma amapereka makina olondola kwambiri. | Amabwera m'mapangidwe osiyanasiyana ndipo amatha kukhala ndi mapangidwe ovuta komanso ovuta. |
| Mtengo | Pamwamba; njira yopanga ndi yovuta, ndipo mtengo wake ndi wokwera kangapo kuposa wa mawilo oponyedwa, kapena kuposa | Pansi; oyenera kupanga-mawu okwera kwambiri; mtengo wabwino kwambiri |
Posankha mawilo a alloy, muyenera kuyeza zomwe mungasankhe potengera zomwe mukufuna. Kuti mugwiritse ntchito m'banja tsiku ndi tsiku, sankhani ma die{1}cast wheels, omwe ndi okwera mtengo kwambiri, amakhala ndi masitayelo osiyanasiyana, ndikuwonetsetsa kuyenda motetezeka. Ngati mukufuna mawilo opepuka kuti muwongolere magwiridwe antchito, kapena ngati mukufuna kusintha, lingalirani mawilo opangidwa, omwe amapereka mphamvu zambiri koma amabwera pamtengo wokwera.
Kuphatikiza apo, muyenera kusamala kwambiri mukamakweza kukula kwa magudumu. Musamachite mwachimbulimbuli zazikulu zazikulu; ndikofunikira kuwonetsetsa kuti zikugwirizana kwambiri ndi magawo ofunikira agalimoto yoyambirira, monga bolt pattern, offset (ET value) ndi pakati bore. Kulephera kutero kungayambitse zovuta kuyika, kugwedezeka kwa msewu kapena ngakhale ngozi zachitetezo. Mukamagula, ndikofunikira kuika patsogolo zinthu zomwe zadutsa chiphaso chovomerezeka ndikuwunika mosamala magudumu kuti muwone zolakwika monga porosity, ming'alu kapena ma burrs. Pewani zinthu zomwe zili ndi zilembo 'zitatu-ayi' zomwe zili ndi dzina lililonse ngati n'kotheka kuti mutsimikizire kuyendetsa bwino galimoto.
