Indlela uTyalo-mali olulahlwayo oluvumela ngayo ukuKhanya kuMveliso weZithuthi zoMbane
Utshintsho lwezithuthi zombane luhlengahlengisa ishishini leemoto kwihlabathi ngesantya esingazange sabonwa ngaphambili. Ngo-2030, izithuthi zombane ziqikelelwa ukuba ziphendule ngaphezu kwe-30% yokuthengiswa kweemoto ezintsha kwihlabathi jikelele, eziqhutywa yimimiselo yolawulo, imfuno yabathengi yokuzinza, kunye nenkqubela phambili ekhawulezayo kubuchwepheshe bebhetri. Nangona kunjalo phantsi kweentloko malunga neekhemikhali zebhetri kunye neziseko zokuhlawula kukho umngeni wobunjineli obusisiseko omisela impumelelo ye-EV: ubunzima .
Yonke igram yobunzima besithuthi ichaphazela ngokuthe ngqo uluhlu lokuqhuba - eyona metric ibalulekileyo yokwamkelwa kwabathengi be-EV. Izifundo ze-International Energy Agency (IEA) zibonisa ukuba ukunciphisa i-10% kubunzima bezithuthi kunokuphucula uluhlu lwe-EV nge-6-8%. Oku kwenza ukuba ukukhanya kungabi yinto yokwenza nje kuphela kodwa ibe sisicwangciso esibalulekileyo kubavelisi be-EV. Kwaye ekudibaneni kokuchaneka, ukusebenza, kunye nokunciphisa ubunzima, ukuchithwa kotyalo-mali kuye kwavela njengeteknoloji ebalulekileyo yokuvumela.
I-Lightweighting Imperative kuYilo lwe-EV
Ngokungafaniyo ne-injini yomlilo yangaphakathi (i-ICE) izithuthi, apho iibhloko ze-injini ezinzima kunye nokuhanjiswa kwamkelwe njengezinto eziqhubekayo, ifilosofi yoyilo lwe-EV iphatha onke amacandelo njengethuba lokunciphisa ubunzima. Ibhokisi yegiya yokunciphisa isithuthi, ukwakhiwa kweemoto, indawo ebiyelweyo ye-inverter, ulwakhiwo lwebhetri, kunye nezinto ezixhonyiweyo zonke ziithagethi zobunzima bokukhanya.
Iindlela zokwenziwa kwemveli zijongene nemida yendalo:
- Ukugalelwa kwesanti kuvelisa iindawo ezirhabaxa kunye neendonga ezingqindilili (ngokuqhelekileyo yi-6-10mm), yongeza ubunzima obungeyomfuneko.
- I-Die casting ibonelela ngeendonga ezinqabileyo kodwa ukhetho oluncinci lwe-alloy kunye neendleko eziphezulu zezixhobo zejometri ezinzima
- Ukutshiza kwi-billet inkunkuma ye-40-60% yezinto eziphathekayo kwaye ayikwazi ukuvelisa i-cavities yangaphakathi
Ukwenziwa kotyalo-mali (ukuphosa iwax elahlekileyo) kuyayiqhawula le mida ngokuvumela ubukhulu bodonga bube buncinci njenge-3.0mm, iijiyometri zangaphakathi ezintsonkothileyo, kunye noluhlu olubanzi lweealloyi - zonke zinemiphetho engaphezulu ecutha ukusetyenzwa.
Ukwenziwa koTyalo-mali kweAluminiyam: Izinto eziKhethekileyo kwii-EVs
I-aluminium alloys, ngokukodwa i-A356.2 (Al-Si7Mg), ibe yinto ekhethiweyo ye-EV yesakhiwo kunye ne-powertrain components. Ngoxinaniso lwe-2.68 g/cm³ - malunga nesinye kwisithathu sentsimbi etyhidiweyo - ialuminiyam ihambisa umlinganiselo wokomelela ukuya kubunzima xa iphathwa ngokufanelekileyo ubushushu.
Izinto eziphambili ze-aluminium EV eziveliswe ngokusasazwa kotyalo-mali ziquka:
UkuNcitshiswa kweZindlu zeGearbox : Ibhokisi yegiya enesantya esinye kwii-EV ezininzi ifuna indlu ekhaphukhaphu kwaye izinzile ngokwemilinganiselo. I-aluminiyam yotyalo-mali oluyi-A356.2 ifikelela ubukhulu bendonga obuyi-3.5mm ngelixa igcina ukuqina okufunekayo kulungelelwaniso lwegiya oluchanekileyo. Ukulungiswa kokushisa kwe-T6 (isisombululo kwi-540 ° C, ukuguga kwi-155 ° C) ivelisa amandla okunyamezela ngaphezu kwe-228 MPa - eyaneleyo kwizicelo zebhokisi kunye nemithwalo ebalulekileyo ye-torque.
I-Inverter kunye ne-Motor Housing : Umbane we-EV wombane uvelisa ubushushu obuninzi ekufuneka buchithwe ngokufanelekileyo. I-Aluminiyam ye-thermal conductivity ye-150 W / m · K - ngaphezu kokuphindwe kathathu kwentsimbi etyhidiweyo - yenza ukuba ibe yinto efanelekileyo kwi-inverter enclosures. Ukuphoswa kotyalo-mali kwenza kudityaniswe amaphiko okupholisa kunye nemijelo yangaphakathi ngokuthe ngqo kwindlu, ukuphelisa imfuno yokushisa okuhlukeneyo.
Amacandelo okuvaleka kwebhetri : Ngelixa iipakethi zebhetri ezigcweleyo zisebenzisa ialuminiyam ekhutshiweyo kunye nestampu, izibiyeli zotyalo-mali, iindawo zokukhwela, kunye neebhokisi ezidityanisiweyo ngaphakathi kolwakhiwo lwebhetri luzuza kubuchule benkqubo bokudala iijiyometri ezintsonkothileyo ezinobunzima obuncinci.
I-Suspension kunye ne-Chassis Brackets : I-EV-specific suspension designs isoloko ifuna izibiyeli zesiko ezivumela i-geometry ehlaziyiweyo kunye nobunzima obuphezulu obungaxutywanga kwiimodyuli zebhetri. Ukwenziwa kotyalo-mali kuvelisa la macandelo nge-topology ephuculweyo - imathiriyeli kuphela apho uhlalutyo loxinzelelo lufuna oko.
Ukuchaneka Okuchaphazela ngokuthe ngqo i-NVH
Izithuthi zombane zisebenza phantse zithe cwaka xa zithelekiswa neenqwelo ze-ICE, zenza iNgxolo, iVibration, kunye noHarshness (NVH) ukusebenza kubaluleke ngakumbi kunangaphambili. Izinto ebezigqunywe ngaphambili yingxolo yenjini ngoku zivakala ngokuvakalayo.
Ukuchaneka komda wotyalo-mali - ngokuqhelekileyo ukunyamezela i-CT6 ngokwe-ISO 8062 nganye - iqinisekisa ukuba izihlalo ezithwele, imingxuma yegiya, kunye nojongano olunyukayo ziveliswa ngaphakathi kwe-±0.02mm. Oku kuchanekileyo kunciphisa ukulungelelaniswa kwegiya, kunciphisa ukuhanjiswa kwe-vibration, kunye nokuphelisa iintshukumo ezincinci ezivelisa ingxolo engafunekiyo. Xa idityaniswe nomatshini we-CNC weendawo ezibaluleke kakhulu zokukhwelana, amacandelo e-EV otyalo-mali afezekisa imigangatho ye-NVH eyahlula i-premium EV brand.
Inkululeko yoYilo yaMacandelo e-EV aDityanisiweyo
Enye yezona nzuzo zinamandla zotyalo-mali lokwenziwa kwe-EV yinkululeko yoyilo . Inkqubo ye-wax elahlekileyo ivumela iinjineli ukuba zidibanise amacandelo amaninzi kwi-casting enye, ukuphelisa ukuhlangana kwendibano, i-fasteners, kunye neendlela ezinokuvuza.
Umzekelo, indlu yemoto ye-EV yemveli inokuba ngamalungu amahlanu ahlukeneyo adityaniswe kunye. Ukulingana kotyalo-mali kunokudibanisa i-flange yokunyuka, ijacket yokupholisa, isihlalo sokuthwala, kunye nokungena kwekhebula kwindawo enye. Le ndlela yokwenza:
- Yehlisa ukubalwa kwenxalenye ngama-40–60%
- Iphelisa ii-gaskets zokutywina kunye neendawo zokuvuza ezinokubakho
- Yehlisa ixesha lokuhlanganisa kunye neendleko
- Ukuphucula ukuqina kwesakhiwo ngokusebenzisa imathiriyeli eqhubekayo
Iipateni zale mihla ze-3D eziprintiweyo zewax ziyomeleza ngakumbi le nkululeko yoyilo, ivumela iinjineli ukuba zenze iijiyometri ezinokuthi zingenzeki ngenaliti yewax eqhelekileyo iyafa. Iitshaneli zokupholisa zangaphakathi ezilandela iindlela eziphuculweyo zobushushu, iziseko zembambo eziphilayo eziphefumlelweyo kuphuculo lwe-topology, kunye nobukhulu beendonga eziguquguqukayo zonke ziyafezekiswa ngeepatheni ze-wax eziprintiweyo ze-3D - itekhnoloji ethi uNingbo Ruican adityaniswe nayo kwi-EV component prototyping workflow.
Uzinzo: i-Casting's Circular Economy Advantage
Njengoko ishishini le-EV lizibeka njengenye indlela ezinzileyo, iinkqubo zokwenziwa kwemveliso ngasemva kwamacandelo e-EV ziza kuqwalaselwa. Ukusatshalaliswa kotyalo-mali kunika iingenelo zozinzo lwendalo:
- Ukuveliswa kobume obukufutshane nomnatha kunciphisa inkunkuma yempahla ibe ngaphantsi kwe-10% (vs. 40–60% yokwenza machining kwibillet)
- I-Aluminiyamu yokuphinda isetyenziswe - ngaphezulu kwe-90% ye-aluminiyam yotyalo-mali inokuphinda isetyenziswe kwakhona ekupheleni kobomi kunye nokuthotywa kwepropathi okuncinci
- Ukusebenza kakuhle kwamandla — iziko zale mihla zokunyibilikisa ezisetyenziswa kutyalo-mali zifikelela kuma-85% amandla okusebenza ngokufanelekileyo vs.
- Ukukhutshwa kwezithuthi ezincitshisiweyo - izinto ezilula zinciphisa ubunzima besithuthi, ziphucula ngokuthe ngqo uluhlu lwe-EV kunye nokunciphisa ukusetyenziswa kwamandla ngexesha lokuphila kwesithuthi.
