Ma aha oo kaliya Yurub in sharciyada aan buuqa lahayn ay "xoojiyeen". Gobolka California ee dalka Maraykanka kuwan ayaa sababay Porsche 911 GT3 sanduuqa gacanta laguma iibin karo halkaas.
Go'aanku wuxuu saameeyaa 911 GT3 iyo 911 GT3 Touring waxaana sabab u ah xaqiiqda ah in sanduuqa gearbox ee baabuurka isboortiga Jarmalku aanu buuxin heerka SAE J1470 ee cabbiraadda qaylada. Si kale haddii loo dhigo… aad bay u “qeyl badan tahay”.
Waxa la sameeyay 1992-kii, tijaabadani waxa ay dhalatay xilli ay baabuurta badankoodu lahaan jireen sanduuqyo gearbox ah oo leh shan ama xitaa afar saamiga. Waxa ugu xiisaha badan ayaa ah in uu jiro imtixaan kale (J2805), oo la sameeyay 2020, in 911 GT3 oo leh sanduuqa gearbox-ku uu gudbi karo, si kastaba ha ahaatee, tijaabadan cusub wali lagama hirgelin California.
Sidee buu imtixaanku u shaqeeyaa?
Inkasta oo dukumeentiga nidaaminaya uu yahay mid aad u faahfaahsan, imtixaanka SAE J1470 waxaa lagu soo koobi karaa si aad u fudud: qaabka la ansixinayo waa inuu dhaafaa (dardargelinta) ee ku xiga makarafoonka kaas oo diiwaangelin doona heerka dhawaaqa uu ku sii daayo decibels. dB)
Ujeedada imtixaankan waa in la cabbiro "heerka buuqa ugu sarreeya ee ku habboon wadista magaalada". Hababka imtixaanku way kala duwan yihiin iyadoo ku xidhan nooca gaadhiga, cufkiisa, awooda iyo nooca sanduuqa.
Guud ahaan, tijaabadu waxay ku lug leedahay dardargelinta xawli buuxa laga bilaabo 50 km/saacaddii ilaa matoorku ka gaadho rpm ugu badnaan. Marka la eego moodooyinka leh gudbinta buug-gacmeedka, tijaabada waxaa lagu sameeyaa qalabka labaad ama saddexaad, iyo xaaladda 911 GT3 waxaa la sameeyaa saddexaad.
Sanduuqa PDK wuu gudbay oo buuggu ma jiro, waayo?
Halka marka laga hadlayo moodooyinka leh gudbinta buug-gacmeedka dardargelinta waa in si buuxda loo sameeyaa, saddexaad, illaa laga gaadho khadka cas, marka la eego moodooyinka leh gudbinta tooska ah, inkasta oo talada si buuxda loo dardargeliyo ay isku mid tahay, haddana ma awoodo, si kastaba ha ahaatee. samee sanduuqa yaree saamiga.
Soo ogow gaadhigaaga xiga
Ku-dardargelinta xawaaraha buuxa ee 911 GT3 oo leh sanduuqa gear-ga ee PDK waxay sababi kartaa hoos u dhacyo dhowr ah (marka hore waxay awood u leedahay inay gaarto 80 km / h), sidaa darteed waligeed ma samaynayso tijaabada iyada oo ceejinta buuxa ah oo sidaas darteed ku gudubto dhib la'aan, ilaa sababtoo ah Tijaabadu waxay dhammaanaysaa ka hor inta aanu mishiinku gaadhin revs buuxa, si sax ah barta keenaysa buug-gacmeedka 911 GT3 inuu "fashilmo".
Marka laga hadlayo dadka Californian-ka ah ee horey u dalbaday Porsche 911 GT3 oo leh sanduuqa gear-ga-gacmeedka, Porsche wuxuu sheegay inay la xiriiri doonaan ganacsatada kala duwan si xaaladda iyaga loogu sharaxo oo ay awoodaan, haddii ay rabaan inay sidaas sameeyaan, dooro kala duwanaanshaha leh PDK gearbox.
