Akukhona e-Europe kuphela lapho imithetho engenamsindo “iqinile”. Esifundazweni sase-US saseCalifornia lezi zibangele I-Porsche 911 GT3 ngebhokisi lezandla alikwazi ukuthengiswa lapho.
Lesi sinqumo sithinta i-911 GT3 ne-911 GT3 Touring futhi kungenxa yokuthi okuhlukile kwebhokisi le-manual yemoto yezemidlalo yaseJalimane akuhlangabezani nezinga lokulinganisa umsindo le-SAE J1470. Ngamanye amazwi… “kunomsindo” kakhulu.
Lesi sivivinyo sadalwa ngo-1992, sazalwa enkathini lapho izimoto eziningi zinama-gearbox anezilinganiso ezinhlanu noma ezine kuphela. Into ebaluleke kakhulu ukuthi sekukhona enye isivivinyo (i-J2805), eyadalwa ngo-2020, ukuthi i-911 GT3 ene-gearbox ye-manual ingadlula, noma kunjalo, lokhu kuhlolwa okusha akukakaqaliswa eCalifornia.
Isivivinyo sisebenza kanjani?
Nakuba idokhumenti eyilawulayo inemininingwane eminingi kakhulu, ukuhlolwa kwe-SAE J1470 kungafingqwa ngendlela elula kakhulu: imodeli ezovunyelwa kufanele idlule (ngokusheshisa) eduze kombhobho ozoqopha izinga lomsindo owukhiphayo ngama-decibel ( dB).
Inhloso yalokhu kuhlola ukukala “izinga eliphezulu lomsindo elihambisana nokushayela emadolobheni”. Izindlela zokuhlola ziyahlukahluka kuye ngohlobo lwemoto, ubukhulu bayo, amandla kanye nohlobo lwebhokisi.
Ngokuvamile, ukuhlola kuhilela ukusheshisa ngesivinini esigcwele ukusuka ku-50 km/h kuze injini ifinyelele ku-rpm yayo ephezulu. Emamodeli anama-manual transmission ukuhlolwa kwenziwa ngegiya lesibili noma lesithathu, kanti uma kuyi-911 GT3 kwenziwa okwesithathu.
Ibhokisi le-PDK liyadlula futhi imanuwali ayikwenzi, ngani?
Ngenkathi esimweni samamodeli ane-manual transmission ukusheshisa kufanele kwenziwe ngokugcwele, okwesithathu, kuze kufike umugqa obomvu, esimweni samamodeli ane-othomathikhi, nakuba isincomo sokusheshisa ngokugcwele siyafana, asikwazi, noma kunjalo, yenza ibhokisi linciphise isilinganiso.
Zitholele imoto yakho elandelayo
Ukusheshisa ngesivinini esigcwele ku-911 GT3 nge-gearbox ye-PDK kungase kubangele ukuncipha okuningana (ekuqaleni ikwazi ukufinyelela cishe ku-80 km/h), ngakho-ke ayikwenzi ukuhlolwa nge-throttle egcwele futhi ngaleyo ndlela idlule ngaphandle kobunzima, kuze kube yilapho isivivinyo siphela ngaphambi kokuthi injini ifinyelele ekuvuselelweni okugcwele, okuyiphuzu elidala ukuthi imanuwali 911 GT3 "yehluleke".
Mayelana nabaseCalifornia asebe-ode iPorsche 911 GT3 eno-gearbox oshintshwayo, abakwaPorsche bathe bazothintwa abadayisi abahlukene ukuze bachazelwe ngalesi simo futhi uma befuna ukwenza kanjalo, bakhethe ukungena. okuhlukile nge-PDK gearbox.
