I-Audi yagqiba ekubeni ithathe elinye inyathelo eliya phambili, ngokubhekiselele kwi-innovation ye-automotive, kunye nengcamango engeyonto entsha kwishishini leemoto kodwa ezisa inzuzo enkulu. Fumana imithombo entsha ye-fiberglass yakwa-Audi.
Ngokunxuseneyo notyalo-mali ekuphuhliseni ii-injini ezikhulayo kunye nezixhobo ezidibeneyo ezivumela ukunciphisa ubunzima, ngelixa ukwandisa ukuqina kwesakhiwo se-chassis kunye nemizimba, i-Audi iphinda iguqukele kwizinto ezidibeneyo, ukwenzela ukusetyenziswa kwamanye amacandelo .
FUNDA KWAKHONA: IToyota inikezela ngembono entsha kwiimoto ezixutyiweyo
I-Audi izinikele ekuphuhliseni nasekukhuliseni le teknoloji, yonke into inenjongo enye: ukugcina ubunzima, ngaloo ndlela iphucula i-agility kunye nokuphathwa kweemodeli zayo zexesha elizayo.
Le yindlela entsha yesebe lophando nophuhliso lwe-Audi: i I-helical fiberglass kunye nemithombo yoxinzelelo lwepolymer eyongeziweyo . Ingcamango eyayisele isetyenziswe yiChevrolet, kwiCorvette C4 ngo-1984.
Inkxalabo ekhulayo kunye nobunzima bokunqunyanyiswa, kunye nefuthe lobunzima obugqithisileyo bezinto zokunqunyanyiswa ekusebenzeni kunye nokusetyenziswa, kwakhokelela ekubeni i-Audi igxininise ekuphuhliseni izikimu zokunqunyanyiswa okulula. Oku kufuneka kuzise iinzuzo ezicacileyo ngokubhekiselele kubunzima, ukusetyenziswa okuphuculweyo kunye nokuphendula okungcono okuguquguqukayo kwiimodeli zayo.
AKUMELE UPHOSEWE: Injini yeWankel, ukujikeleza okumsulwa
Lo mzamo wobunjineli owenziwe ngu-Audi, kunye no-Joachim Schmitt oyintloko yeprojekthi, wafumana intsebenziswano efanelekileyo kwinkampani yase-Italiya i-SOGEFI, ebambe ilungelo elilodwa lomenzi weteknoloji kunye ne-brand ye-Ingolstadt.
Uthini umahluko kunye nemithombo yentsimbi eqhelekileyo?
UJoachim Schmitt ubeka umahluko ngokwembono: kwi-Audi A4, apho ukunqunyanyiswa kwemithombo kwi-axle yangaphambili inobunzima be-2.66kg nganye, i-fiberglass entsha yokuqinisa i-polymer (GFRP) imithombo kuphela inobunzima be-1.53kg nganye kwiseti efanayo. Umahluko wobunzima obungaphezulu kwe-40%, kunye nenqanaba elifanayo lokusebenza kunye neenzuzo ezongezelelweyo esiya kukuchazela ngomzuzwana.
Iveliswa njani le mithombo mitsha ye-GFRP?
Ukubuyela kancinane kwinto eyimithombo ye-coil compression, yenzelwe ukuqokelela amandla ngexesha lokunyanzeliswa kunye nokuzibhokoxa kwicala lokwandiswa. Ngokuqhelekileyo ziveliswa kwintambo yensimbi, ene-cylindrical shape. Xa kuyimfuneko ukusebenzisa imikhosi ephezulu ye-torsional kwiindawo ezincinci, iingcingo zibunjwa kunye nezinye iimilo, kubandakanywa ne-helical ehambelanayo, ngaloo ndlela zenza i-spiral kwisiphelo ngasinye.
Ubume bemithombo
Ulwakhiwo lwale mithombo mitsha inondoqo ophuhla ngomqulu omde we-fiberglass, ephothiweyo kwaye ifakwe kwi-epoxy resin, apho kamva umatshini unoxanduva lokusonga i-spirals ngemicu eyongezelelweyo edibeneyo, kwii-engile ezitshintshanayo ze-± 45 °, i-axis yobude.
UKUBA UKHUMBULE: Yenziwa ngolu hlobo injini yakwaNissan GT-R
Olu nyango lubaluleke ngokukhethekileyo, kuba kungenxa yentsebenziswano phakathi kwala maleko axhasayo apho aya kunika intwasahlobo eyongezelelweyo yoxinzelelo kunye neempawu ze-torsion. Ngale ndlela, imithwalo ye-torsional ngentwasahlobo iguqulwa yi-fibers ibe yi-elasticity kunye ne-compression forces.
Isigaba sokugqibela semveliso
Kwinqanaba lokugqibela lemveliso, intwasahlobo isemanzi kwaye ithambile. Kule nqanaba apho i-alloy yensimbi eneqondo lokushisa eliphantsi lokunyibilika iqaliswa, kwaye ke intwasahlobo kwi-GFRP ibhaka kwi-oven engaphezulu kwe-100 °, ukwenzela ukuba i-alloy metallic idibanise ngokuvumelana, kunye nokuqina kwe-fiberglass. .
Ziziphi iingenelo zale mithombo ye-GFRP, xa kuthelekiswa nentsimbi yendabuko?
Ukongeza kwi-advanteji yobunzima obucacileyo malunga ne-40% ngentwasahlobo, imithombo ye-GFRP ayichatshazelwa kukuhlwa, nasemva kweekhilomitha ezininzi ezinemikrwelo kunye neentanda ezibonakala kwisakhiwo sazo. Ngaphezu koko, azinamanzi ngokupheleleyo, oko kukuthi, zixhathisa ukusebenzisana nezinye izinto zekhemikhali ezinobungozi, ezifana neemveliso zokucoca iivili.
Enye yeenzuzo zale mithombo ye-GFRP inxulumene nokuthembeka kunye nokuqina kwayo, apho ibonakaliswe kwiimvavanyo ukuze ikwazi ukuqhuba i-300,000 km ngaphandle kokulahlekelwa iipropati ezi-elastic, idlula kakhulu ubomi obuncedo bamaqabane abo amisiweyo, i-shock absorbers. .
UMOTO ONOKUTHETHA: Zonke iinkcukacha zenjini entsha yakwaMazda eyi-1.5 Skyactiv D
Le yinkqubo yokuqala apho i-Audi ivelise iiprototypes zovavanyo, ngaphambi kokuba iqalise ukuvelisa amawaka ala macandelo ngonyaka.
Ngokohlobo lwamakhonkco, ukuvelisa le mithombo kwizinto ezidibeneyo kufuna amandla amancinci kunemithombo yensimbi yendabuko, nangona kunjalo, iindleko zabo zokugqibela ziphezulu kancinci, nto leyo enokuthi ithintele ubuninzi babo iminyaka embalwa. Ekupheleni konyaka, kulindeleke ukuba i-Audi ibhengeze le mithombo yemodeli ephezulu.
