Akukhona eYurophu kuphela ukuba imithetho engenangxolo iye "iqinisa". Kwilizwe laseMelika laseCalifornia ezi zibangele Porsche 911 GT3 enebhokisi yezandla ayinakuthengiswa apho.
Isigqibo sichaphazela i-911 GT3 kunye ne-911 GT3 Touring kwaye kungenxa yokuba i-gearbox ye-manual eyahlukileyo yemoto yezemidlalo yaseJamani ayihambelani nomgangatho we-SAE J1470 wokulinganisa ingxolo. Ngamanye amazwi… “ingxolo” kakhulu.
Yadalwa ngo-1992, olu vavanyo lwazalwa ngexesha apho iimoto ezininzi zineebhokisi zegiya ezinemilinganiselo emihlanu okanye emine kuphela. Eyona nto inomdla kakhulu kukuba sele kukho olunye uvavanyo (i-J2805), eyakhiwe ngo-2020, ukuba i-911 GT3 enebhokisi yegiya ye-manual ingadlula, nangona kunjalo, olu vavanyo lutsha alukaphunyezwa eCalifornia.
Lusebenza njani uvavanyo?
Nangona uxwebhu olulawulayo luchazwe ngokugqithiseleyo, uvavanyo lwe-SAE J1470 lunokushwankathelwa ngendlela elula kakhulu: imodeli eya kuvunywa kufuneka idlule (ngokukhawuleza) ecaleni kwe-microphone eya kurekhoda inqanaba lengxolo eliphuma kuyo kwiidecibels ( dB).
Injongo yolu vavanyo kukulinganisa “elona nqanaba liphezulu lengxolo elihambelana nokuqhuba ezidolophini”. Iindlela zokuvavanya ziyahluka ngokuxhomekeke kuhlobo lwesithuthi, ubunzima bayo, amandla kunye nohlobo lwebhokisi.
Ngokuqhelekileyo, uvavanyo lubandakanya ukukhawuleza kwisantya esipheleleyo ukusuka kwi-50 km / h de injini ifikelele kwi-rpm yayo ephezulu. Kwimeko yeemodeli ezine-manual transmission, uvavanyo lwenziwa kwi gear yesibini okanye yesithathu, kwaye kwimeko ye-911 GT3 yenziwa kweyesithathu.
Ibhokisi yePDK iyadlula kwaye incwadana ayifuni, ngoba?
Ngelixa kwimeko yeemodeli ezinokuhanjiswa kwencwadana ukukhawuleza kufuneka kwenziwe ngokupheleleyo, okwesithathu, de kufike umgca obomvu, kwimeko yeemodeli ezinokuhanjiswa ngokuzenzekelayo, nangona isincomo sokukhawulezisa ngokupheleleyo siyafana, asikwazi, nangona kunjalo, yenza ibhokisi inciphise umlinganiselo.
Fumana imoto yakho elandelayo
Ukukhawulezisa ngesantya esipheleleyo kwi-911 GT3 nge-gearbox ye-PDK kunokubangela ucutho oluninzi (ekuqaleni iyakwazi ukufikelela malunga ne-80 km/h), ngoko ayikhe ilwenze uvavanyo nge-throttle epheleleyo kwaye iyigqithise ngaphandle kobunzima, de kube ngenxa yokuba uvavanyo luphela phambi kokuba injini ifikelele revs ngokupheleleyo, ngokuchanekileyo inqaku ebangela manual 911 GT3 ukuba "yasilela".
Ngokuphathelele abantu baseCalifornia ababesele beyi-odole i-Porsche 911 GT3 ene-gearbox ye-manual, i-Porsche ithe bayakuqhagamshelwa ngabathengisi abahlukeneyo ukuze bacaciselwe imeko kwaye bakwazi, ukuba bafuna ukwenjenjalo, bakhethe. Umahluko ngePDK gearbox.
