I-ASF - I-Audi Space Frame

I-ASF iqukethe ikakhulukazi izingxenye ezivaliwe zezingxenye ezixhunywe komunye nomunye ngemihlangano ebunjiwe yomjovo. Ngokusho kwe-Audi, ukuvuselelwa kabusha kuphindwe kahlanu kunensimbi.

Amandla aphelele adingekayo ekukhiqizeni yi-152-163 GJ uma kuqhathaniswa ne-127 GJ yenqola yensimbi efanayo.

Kuthuthukisiwe

Ngokuyinhloko, zifakwa ngephrofayili enjengebhokisi. Ama-alloys asetshenzisiwe angama-Al-Si alloys angashicilelwe anokuqukethwe okungu-Si okungaphezu kuka-0,2% ukuqinisekisa ukugeleza kwezulu nokuqina kwezulu lapho kuguga okufakelwayo.

amashidi

Isetshenziselwa amaphaneli athwala imithwalo, ama-slabs, uphahla nezingodo zomlilo, zibala u-45% wesisindo sesakhiwo. Ubukhulu bawo bukhulu ngokuphindwe ka-1.7-1.8 kunobo bensimbi. I-alloy 5182 esetshenzisiwe esifundeni se-T4 (ekhubazeka kakhulu) enomkhawulo wokunwebeka we-140-395 MPa. Ingasekelwa yize ine-magnesium engaphansi kuka-7% ngenxa yobukhona bezinye izingulube.

Amayunithi wabalingisi

Zisetshenziswa ezindaweni ezingaphansi kwengcindezi enkulu kakhulu.

Zenziwa kusetshenziswa inqubo ebizwa nge-VACURAL, efaka ukujova i-aluminium ewuketshezi kuzikhunta zokuhlanza ukuthola:

Ikhwalithi ephezulu nokufana, i-porosity ephansi kakhulu yokuqinisekisa izakhiwo eziphezulu zemishini kuhlanganiswe nobunzima obudingekayo ukumelana nokukhathala;

Ukudidiyelwa okuhle kuyadingeka ekujoyineni amaphrofayli.

Amasu wokuxhuma

Kusetshenziswa amasu amaningi:

Ukushisela kwe-MIG: kusetshenziselwa amashidi amancane nokujoyina ama-node kuphrofayili;

Ukushisela amabala: insimbi engafinyeleleki ngezinsimbi zezipikili;

Ukuqothula: okubaluleke kakhulu ekubukeni kwesakhiwo ngenxa yokwehla kokumelana okungaguquki; esetshenziselwa ukuhlanganisa amashidi ukuqinisa indawo enwetshiwe;

Ukuphakamisa: kusetshenziselwa ukuthwala izinto ezinendawo ekhulisiwe; ngobukhulu obufanayo, inokumelana okungaphezulu kuka-30% uma kuqhathaniswa nokushisela; futhi inenzuzo yokudinga amandla amancane futhi ayishintshi ukwakheka kwento.

Izinto zokunamathisela ezakhiwe ngesakhiwo: ezisetshenziselwa ingilazi engaguquki, emalungeni omnyango nakuma-bonnet (kanye ne-screwing), ekusekelweni kwe-absorber absorber (kanye ne-riveting ne-welding).

Ukuhlanganisa

Ngemuva kokubumba, ukuhlangana kwenzeka nge-robotic welding yezingxenye.

Ukuqedela kwenziwa ngokugaya nokugcoba nge-cations ezi-3 (iZn, Ni, Mn), ezikhuthaza ukunamathiselwa kongqimba lwe-cataphoresis ngokuntywila.

Umdwebo wenziwa ngendlela efanayo nemizimba yensimbi. Kakade kulesi sigaba, ukuguga okufakelwayo kokuqala kuyenzeka, okube sekuqedelwa ngokunye ukwelashwa kokushisa ku-210 ° C imizuzu engama-30.
