Amasondo e-car light alloy:

Embonini yezimoto, amasondo e-alloy angamasondo enziwe nge-alloy ye-aluminium noma i-magnesium.Ama-alloys ayinhlanganisela yensimbi nezinye izakhi.Ngokuvamile zinikeza amandla amakhulu phezu kwezinsimbi ezihlanzekile, ngokuvamile ezithambile kakhulu futhi zidonsa kakhulu.Ama-alloys e-aluminium noma e-magnesium ngokuvamile alula ngamandla afanayo, ahlinzeka ngokuqhutshwa kokushisa okungcono, futhi ngokuvamile akhiqiza ukubukeka kwezimonyo okuthuthukisiwe phezu kwamasondo ensimbi.Nakuba insimbi, into evame ukusetshenziswa kakhulu ekukhiqizweni kwamasondo, iyingxubevange yensimbi nekhabhoni, igama elithi “isondo lengxubevange” ngokuvamile ligcinelwa amasondo enziwe ngama-alloys angenayo insimbi.

Amasondo alula angathuthukisa ukuphatha ngokunciphisa i-unspring mass, okuvumela ukumiswa ukuthi kulandele indawo eduze kakhulu futhi ngaleyo ndlela kuthuthukise ukubamba, nokho akuwona wonke amasondo e-alloy alula kunezilinganiso zawo zensimbi.Ukwehliswa kwesisindo sezimoto zizonke kungasiza ekunciphiseni ukusetshenziswa kukaphethiloli.

Ukulawulwa kokushisa okungcono kanye nedizayini yesondo evuleke kakhudlwana kungasiza ukususa ukushisa okuvela kumabhuleki, okuthuthukisa ukusebenza kwebhuleki ezimeni zokushayela ezidingeka kakhulu futhi kunciphise ithuba lokuncipha kokusebenza kwamabhuleki noma ngisho nokwehluleka ngenxa yokushisa ngokweqile.

Amasondo e-alloy nawo athengelwa izinjongo zezimonyo nakuba ama-alloys ashibhile asetshenziswa ngokuvamile awakwazi ukumelana nokugqwala.Ama-alloys avumela ukusetshenziswa kwezinto ezikhangayo ezingenalutho zensimbi, kodwa lezi zidinga zivalwe ngopende noma ngamasondo.Noma ngabe avikeleke kanjalo amasondo asetshenziswayo ekugcineni azoqala ukugqwala ngemuva kweminyaka emi-3 kuya kwemi-5 kodwa ukulungiswa kabusha sekutholakala kabanzi ngezindleko.Izinqubo zokukhiqiza nazo zivumela imiklamo eyinkimbinkimbi, enesibindi.Ngokuphambene, amasondo ensimbi avamise ukucindezelwa eshidini lensimbi, abese eshiselwa ndawonye (imvamisa eshiya amaqhuqhuva angabukeki) futhi kufanele apendwe ukugwema ukugqwala kanye/noma kufihlwe ngamakhava amasondo/izikepisi zehabhu.

Amasondo e-alloy abiza kakhulu ukukhiqiza kunamasondo ensimbi ajwayelekile, ngakho-ke awavamile ukufakwa njengempahla evamile, kunalokho adayiswa njengezengezo ozikhethela noma njengengxenye yephakheji yokunquma ebiza kakhulu.Kodwa-ke, amasondo e-alloy avame kakhulu kusukela ngo-2000, manje anikezwa ngezimoto ezisezingeni eliphezulu kanye ne-subcompact, uma kuqhathaniswa neminyaka eyishumi ngaphambili lapho amasondo e-alloy ayevame ukungezona izinketho zemboni ezimotweni ezingabizi.Amasondo engxubevange kudala afakwa njengezisetshenziswa ezijwayelekile ezimotweni zenani eliphezulu zikanokusho noma zezemidlalo, ezinamasondo amasondo amakhulu noma “okukhethekile” okuyizinketho.Izindleko eziphezulu zamasondo e-alloy ziwenza akhange kumasela;ukulwa nalokhu, abakhiqizi bezimoto nabathengisi bavame ukusebenzisa amantongomane okukhiya adinga ukhiye okhethekile wokuwasusa.

Amasondo amaningi e-alloy akhiqizwa kusetshenziswa i-casting, kodwa amanye akhiwe.Amasondo afojiwe ngokuvamile alula, anamandla, kodwa abiza kakhulu kunamasondo acijile.Kunezinhlobo ezimbili zamasondo omgunyathi: ucezu olulodwa kanye ne-modular.Amasondo afojiwe ajwayelekile angase abe nomklamo oneziqephu ezimbili noma ezintathu.Amasondo ajwayelekile anezicucu eziningi ahlanganisa isisekelo serimu elingaphakathi, udebe lwangaphandle kanye nocezu olumaphakathi nesondo elinezimbobo zamantongomane.Zonke izingxenye zesondo le-modular ziphethwe ngamabhawudi.I-Rayone KS001 ingelinye lamasondo omgunyathi aneziqephu ezintathu ezaziwa kakhulu ngokwesibonelo.

Ukukhethwa okukhulu kwamasondo engxubevange kuyatholakala kubanikazi bezimoto abafuna amasondo alula, abukekayo, angavamile, kanye/noma amakhulu ezimotweni zabo.Nakuba ukushintsha inhlanganisela yesondo lensimbi nethayi elijwayelekile ngamasondo e-alloy alula kanye namasondo ephrofayili okungenzeka abe phansi kungase kubangele ukusebenza okuthuthukile nokubamba, lokhu akubambi ngempela uma kusetshenziswa amasondo aya ngokwandayo.Ucwaningo lweCar and Driver olwenziwe kusetshenziswa ukukhethwa kwamasondo engxubevange anobukhulu obuhlukene ukusuka ku-15” kuya ku-21” ku-(38,1cm kuya ku-53,34 cm) wonke afakwe ngendlela efanayo nemodeli yamathayi abonisa ukuthi kokubili ukusheshisa nokonga kukaphethiloli. wahlupheka ngamasondo amakhulu.Baphinde baphawula ukuthi ukunethezeka kokugibela nomsindo kuphazamisekile ngenxa yamasondo amakhulu.

Izindlela Zokukhiqiza:

Ukuqambakungenziwa ngenqubo eyodwa noma enezinyathelo eziningi ezakha ama-alloys ahlukahlukene e-magnesium, ngokuvamile i-AZ80, ZK60 (MA14 eRussia).Amasondo akhiqizwa ngale ndlela ngokuvamile anokuqina okuphezulu kanye ne-ductility kunamasondo e-aluminium, nakuba izindleko ziphakeme kakhulu.

I-High Pressure die Casting (HPDC).Le nqubo isebenzisa idayizi ehlelwe emshinini omkhulu onamandla okuvala aphezulu ukuze ubambe idayisi evaliwe.I-magnesium encibilikisiwe ithululelwa epayipini lokugcwalisa elibizwa ngokuthi i-shot sleeve.I-piston iphusha insimbi ku-die ngesivinini esikhulu nokucindezela, i-magnesium iqina futhi i-die ivuliwe futhi isondo liyakhululwa.Amasondo akhiqizwe ngale ndlela anganikeza ukuncipha kwentengo kanye nokuthuthukiswa kokumelana nokugqwala kodwa ane-ductile encane futhi enamandla aphansi ngenxa yemvelo ye-HPDC.

I-Low pressure Die casting (LPDC).Le nqubo ivamise ukusebenzisa i-steel die, ihlelwa ngaphezu kwe-crucible egcwele i-magnesium encibilikisiwe.Ngokuvamile i-crucible ivalwa ngokumelene ne-die futhi ingxube yegesi enomfutho womoya/yekhava isetshenziswa ukuphoqa insimbi encibilikisiwe ukuthi ikhuphuke ngeshubhu yokugcwalisa enjengotshani edayini.Uma ecutshungulwa kusetshenziswa izindlela zokuzijwayeza ezingcono kakhulu Amasondo e-LPDC anganikeza ukuthuthuka kokusebenza kwe-ductility phezu kwamasondo e-magnesium e-HPDC nanoma imaphi amasondo e-aluminium asakazwayo, ahlala e-ductile encane kune-magnesium engumgunyathi.

Ukusakazwa kwamandla adonsela phansi.Amasondo e-magnesium-cast-cast abekhiqizwa kusukela ekuqaleni kwawo-1920 futhi ahlinzeka nge-ductility enhle, kanye nezakhiwo ezihlobene ngaphezu kwalokho okungenziwa ngokusakazwa kwe-aluminium.Izindleko zamathuluzi amasondo adonsela phansi aphakathi kwezindleko ezishibhe kakhulu kunoma iyiphi inqubo.Lokhu kuye kwavumela ukukhiqizwa kwe-batch encane, ukuguquguquka kokuklama kanye nesikhathi esifushane sokuthuthukiswa.
