Audi yahisemo gutera indi ntera, mubijyanye no guhanga ibinyabiziga, hamwe nigitekerezo kitari gishya mubikorwa byimodoka ariko bizana inyungu nyinshi. Menya Audi nshya ya fiberglass.
Mu buryo bubangikanye nishoramari mugutezimbere moteri ikora neza nibikoresho bikomatanya bigabanya kugabanya ibiro, mugihe byongera ubukana bwimiterere ya chassis numubiri, Audi yongeye guhindukirira ibikoresho, kugirango ikoreshwe mubindi bice.
REBA NAWE: Toyota itanga igitekerezo gishya kumodoka ya Hybrid
Audi yiyemeje guteza imbere no gukwirakwiza ikoranabuhanga, byose bifite intego imwe: kuzigama ibiro, bityo bikazamura ubuhanga no gukoresha imiterere yigihe kizaza.
Nibintu bishya byishami ryubushakashatsi niterambere rya Audi: the helical fiberglass na polymer byongerewe imbaraga zo guhonyora . Igitekerezo cyari kimaze gukoreshwa na Chevrolet, muri Corvette C4 mu 1984.
Guhangayikishwa cyane nuburemere bwo guhagarikwa, hamwe nuburemere bwuburemere bukabije bwibintu byahagaritswe kumikorere no kubikoresha, byatumye Audi yibanda kumajyambere ya gahunda yo guhagarika byoroheje. Ibi bigomba kuzana inyungu zisobanutse mubijyanye nuburemere, kunoza imikoreshereze hamwe nigisubizo cyiza kiva mubitegererezo byacyo.
SI UKUBURA: Moteri ya Wankel, kuzunguruka leta
Iyi mbaraga yubuhanga bwakozwe na Audi, hamwe na Joachim Schmitt uyoboye umushinga, babonye ubufatanye bwiza muri societe yo mubutaliyani SOGEFI, ifite ipatanti ihuriweho nikoranabuhanga hamwe nikirango cya Ingolstadt.
Ni irihe tandukaniro hamwe n'amasoko y'ibyuma bisanzwe?
Joachim Schmitt ashyira itandukaniro mubitekerezo: muri Audi A4, aho amasoko yo guhagarikwa kumurongo wimbere ufite uburemere bugera kuri 2.66kg buri umwe, fibre nshya ya fiberglass ishimangira polymer (GFRP) ipima 1.53kg imwe kumurongo umwe. Itandukaniro ryibiro birenga 40%, hamwe nurwego rumwe rwimikorere ninyungu zinyongera tuzagusobanurira mukanya.
Nigute aya masoko mashya ya GFRP yakozwe?
Tugarutse gato kubintu byo guhunika coil, bigenewe gukusanya imbaraga mugihe cyo kwikuramo no kubikoresha muburyo bwo kwaguka. Mubisanzwe bikozwe mumashanyarazi, hamwe na silindrike. Iyo bibaye ngombwa gukoresha imbaraga za torsional zo hejuru mumwanya muto, insinga zibumbabumbwe nizindi shusho, harimo na parike ihanamye, bityo ikazunguruka kuri buri mpera.
Imiterere y'amasoko
Imiterere yaya masoko mashya afite intangiriro ikura binyuze mumuzingo muremure wa fiberglass, igahuzwa kandi igaterwa na epoxy resin, aho nyuma imashini ishinzwe kuzinga imizunguruko hamwe nizindi fibre yibumbiye hamwe, kuruhande rwa ± 45 °, ugereranije umurongo muremure.
KWIBUKA: Nuburyo moteri ya Nissan GT-R ikorwa
Ubu buvuzi bufite akamaro kanini, kubera ko binyuze mu mikoranire hagati yibi byiciro byombi bizatanga isoko yinyongera yo kwikuramo hamwe na torsion. Muri ubu buryo, imitwaro ya torsional inyuze mumasoko ihindurwa na fibre muburyo bworoshye kandi bwo kwikuramo.
Icyiciro cyanyuma cyo gukora
Mu cyiciro cya nyuma cyo gutanga umusaruro, isoko iracyatose kandi yoroshye. Aha niho hashyirwaho umusemburo wibyuma hamwe nubushyuhe buke bwo gushonga, hanyuma isoko muri GFRP itekwa mu ziko hejuru ya 100 °, kugirango ibivanze byuma bishobore guhuzwa mubwumvikane, hamwe no gukomera kwa fiberglass .
Ni izihe nyungu z'aya masoko ya GFRP, ugereranije n'ibyuma gakondo?
Usibye uburemere bugaragara bwa 40% mugihe cyimpeshyi, amasoko ya GFRP ntabwo yangizwa no kwangirika, kabone niyo haba nyuma yibirometero byinshi hamwe no gushushanya hamwe nibice bigaragara mumiterere yabyo. Byongeye kandi, birinda amazi rwose, ni ukuvuga, birwanya imikoranire nibindi bikoresho bya chimique byangiza, nkibikoresho byoza ibiziga.
Ikindi cyiza cyaya masoko ya GFRP kijyanye no kwizerwa kwabo no kuramba, aho bagaragaye mubizamini kugirango babashe kwiruka kilometero 300.000 batabuze imitungo yabo ya elastique, ahanini bakarenza ubuzima bwingirakamaro bwabafatanyabikorwa babo bahagaritse, abikuramo. .
BYINSHI KUVUGA: Ibisobanuro byose bya moteri nshya ya 1.5 Skyactiv D.
Nibikorwa byambere aho Audi yagiye ikora prototypes zayo, mbere yo gutangira gutanga ibihumbi nibi bice buri mwaka.
Ukurikije ikirango cyimpeta, kubyara ayo masoko mubikoresho bisaba imbaraga nke ugereranije nibyuma gakondo, icyakora, igiciro cyanyuma kiri hejuru gato, kikaba ari ikintu gishobora kubangamira ubwiyongere bwabo mumyaka mike. Umwaka urangiye, biteganijwe ko Audi izatangaza ayo masoko kumurongo wohejuru.
