I-Audi inqume ukuthatha elinye igxathu eliya phambili, mayelana nokusungulwa kwezimoto, nomqondo ongeyona into entsha embonini yezimoto kodwa oletha izinzuzo ezinkulu. Zitholele imithombo entsha ye-fiberglass yakwa-Audi.
Ngokuhambisana nokutshalwa kwezimali ekuthuthukisweni kwezinjini ezikhulayo kanye nezinto eziyinhlanganisela ezivumela ukunciphisa isisindo, kuyilapho kukhulisa ukuqina kwesakhiwo se-chassis nemizimba, i-Audi iphinda iphendukela ezintweni eziyinhlanganisela, ukuze isetshenziswe kwezinye izingxenye .
FUNDA OLUNYE: I-Toyota yethula umcabango omusha wezimoto ezixubile
I-Audi izibophezele ekuthuthukiseni nasekukhuliseni lobu buchwepheshe, konke ngenjongo eyodwa: ukonga isisindo, ngaleyo ndlela kuthuthukiswe ukushesha nokuphatha amamodeli ayo esikhathi esizayo.
Lena imfashini entsha yomnyango wocwaningo nentuthuko wakwa-Audi: the I-fiberglass ye-helical kanye nemithombo yokucindezela ye-polymer eqinisiwe . Umbono owawuvele usetshenziswe ngabakwaChevrolet, kuCorvette C4 ngo-1984.
Ukukhathazeka okukhulayo ngesisindo sokumiswa, kanye nomthelela wesisindo eseqile sezinto ezimisiwe ekusebenzeni nasekusetshenzisweni, kuholele ekutheni i-Audi igxile ekuthuthukisweni kwezikimu zokumisa ezilula. Lokhu kufanele kulethe izinzuzo ezicacile mayelana nesisindo, ukusetshenziswa okuthuthukisiwe kanye nokuphendula okungcono okuguquguqukayo okuvela kumamodeli ayo.
AKUMELE UPHUTHELWE: I-Wankel Engine, ukuzungezisa isimo
Lo mzamo wobunjiniyela we-Audi, no-Joachim Schmitt oyinhloko yephrojekthi, uthole ukubambisana okuhle enkampanini yase-Italy i-SOGEFI, ephethe ilungelo lobunikazi elihlangene lobuchwepheshe nomkhiqizo we-Ingolstadt.
Uyini umehluko ngemithombo yensimbi evamile?
U-Joachim Schmitt ubeka umehluko ngombono: ku-Audi A4, lapho i-suspension springs ku-axle yangaphambili inesisindo esingafika ku-2.66kg ngayinye, iziphethu ze-fiberglass reinforced polymer (GFRP) zinesisindo esingu-1.53kg kuphela ngesethi efanayo. Umehluko wesisindo esingaphezu kuka-40%, ngezinga elifanayo lokusebenza nezinzuzo ezengeziwe esizokuchazela zona maduzane.
Zikhiqizwa kanjani lezi ziphethu ze-GFRP ezintsha?
Ukubuyela kancane kulokho okuyiziphethu zokucindezela ikhoyili, zenzelwe ukuqongelela amandla ngesikhathi sokucindezelwa futhi ziwasebenzise ekuqondeni. Ngokuvamile zikhiqizwa ngocingo lwensimbi, olunomumo we-cylindrical. Uma kudingekile ukusebenzisa amandla aphakeme ashukumisayo ezindaweni ezincane, izintambo zibunjwa nezinye izimo, kuhlanganise ne-parallel helical, ngaleyo ndlela zakha ukuvunguza ekugcineni ngakunye.
Ukwakheka kweziphethu
Ukwakheka kwalezi ziphethu ezintsha kunomongo okhula ngomqulu omude we-fiberglass, elukiwe futhi efakwe ne-epoxy resin, lapho kamuva umshini unesibopho sokusonga ama-spiral ngemicu eyengeziwe eyinhlanganisela, kwamanye ama-engeli angu-±45°, uma kuqhathaniswa i-axis longitudinal.

Lokhu kwelashwa kubaluleke ngokukhethekile, ngoba kungenxa yokusebenzisana phakathi kwalezi zingqimba ezisekelanayo lapho kuzonikeza intwasahlobo izici ezengeziwe zokucindezelwa kanye ne-torsion. Ngale ndlela, imithwalo ye-torsional entwasahlobo iguqulwa imicu ibe yi-elasticity kanye namandla okucindezela.
Isigaba sokugcina sokukhiqiza
Esigabeni sokugcina sokukhiqiza, intwasahlobo isemanzi futhi ithambile. Kungalesi sikhathi lapho kwethulwa khona ingxubevange yensimbi enezinga eliphansi lokushisa elincibilikayo, bese kuthi isiphethu ku-GFRP sibhakwa kuhhavini esingaphezu kuka-100 °, ukuze ingxubevange yensimbi ihlanganise ngokuvumelana, ngokuqiniswa kwe-fiberglass. .
Yiziphi izinzuzo zalezi ziphethu ze-GFRP, uma kuqhathaniswa nezinsimbi zendabuko?
Ngaphezu kwenzuzo esobala yesisindo esingaba ngu-40% entwasahlobo ngayinye, iziphethu ze-GFRP azithintwa ukugqwala, ngisho nangemva kwamakhilomitha amaningi anemihuzuko nokuqhekeka okubonakala esakhiweni sazo. Ngaphezu kwalokho, awanamanzi ngokuphelele, okungukuthi, amelana nokusebenzelana nezinye izinto zamakhemikhali abrasive, njengemikhiqizo yokuhlanza amasondo.
Enye yezinzuzo zalezi ziphethu ze-GFRP zihlobene nokuthembeka nokuqina kwazo, lapho ziboniswe khona ekuhlolweni ukuze zikwazi ukugijima i-300,000 km ngaphandle kokulahlekelwa izakhiwo zazo ezinwebekayo, ezidlula kakhulu impilo ewusizo yabalingani babo besethi yokumiswa, ama-shock absorbers. .

Lena inqubo yokuqala abakwa-Audi abebekhiqiza ngayo ama-prototypes okuhlola, ngaphambi kokuqala ukukhiqiza izinkulungwane zalezi zingxenye minyaka yonke.
Ngokusho kohlobo lwamandandatho, ukukhiqiza lezi ziphethu ezintweni ezihlanganisiwe kudinga amandla amancane kunemithombo yensimbi yendabuko, noma kunjalo, izindleko zabo zokugcina ziphakeme kancane, okuyinto engase ivimbele ubuningi babo iminyaka embalwa eyengeziwe. Ekupheleni konyaka, i-Audi kulindeleke ukuthi imemezele lezi ziphethu zemodeli esezingeni eliphezulu.
