Marka ay timaado usha wareejinta, waa inaan ka hadalnaa horumarka degdegga ah ee usha wareejinta elektaroonigga ah, noocyada kale ee usha wareejinta, iyo sharraxaad kale oo faahfaahsan.
Hadda waxaa suuqa yaal afar nooc oo shifters ah. Laga soo bilaabo taariikhda horumarinta, waa: MT (ManualTransmissionShifter, manual shift lever) - > AT (AutomaticTransmissionTransmissionShifter, Automatic gear lever) ilaa AMT (AutomatedMechanicalTransmissionShifter, semi-automatic gear lever), GSM (GearShiftModule, ama SBW = ShiftByWire, electronic gear lever)
Maadaama usha wareejinta ee MT iyo AT ay asal ahaan yihiin qaab-dhismeed farsamo oo saafi ah, xiriir yar ayay la leedahay usha wareejinta elektaroonigga ah. Sidaa darteed, sida lagu sharraxay bilowgii, tiir kale ayaa la sameeyay.
Kahor inta aynaan ka hadlin qalabka elektaroonigga ah ee loo yaqaan 'transfer lever', aan ka hadalno qalabka 'AMT'.
Kaaliyaha qalabka AMT ma aha oo kaliya inuu dhaxlo qaab-dhismeedka farsamada ee MT/AT si fiican, laakiin sidoo kale wuxuu adeegsadaa kicinta elektromagnetic-ka si uu u aqoonsado boosaska qalabka ama uusan aqoonsan, oo kaliya calaamadaha soo saarista boosaska qalabka kala duwan. Si fudud haddii loo dhigo, kabaalka qalabka AMT ama qaybta isku xirka waxaa lagu qalabeeyay birlabyo leh tiirar togan iyo kuwa taban oo ku yaal waqooyiga iyo koonfurta, waxayna beddelaan booskooda iyada oo loo marayo boosaska qalabka kala duwan. Guddiga saldhigga (PCB) oo ku qalabaysan SENSOR IC oo ku yaal kabaalka wareejinta AMT wuxuu soo saaraa kicinta magnetic-ka ee birlabyada boosaska kala duwan wuxuuna soo saaraa durdurro kala duwan. Qaybta processor-ka gaariga waxay u wareejin doontaa geerka u dhigma durdurrada ama calaamadaha kala duwan.
Marka laga eego dhinaca qaab-dhismeedka, usha wareejinta AMT waa mid ka adag usha wareejinta MT/AT, tignoolajiyadu way kor u kacday, qiimaha hal cutub ayaa ka qaalisan, laakiin OEM-ka gaariga, isticmaalka usha wareejinta AMT, ilaa inta isbeddel yar, taas oo ah, inta badan isticmaali karto tareenka korontada ee MT, sidaa darteed kharashka guud ee gaariga wuu hooseyn doonaa
Maxaa loo isticmaalaa kabaalka wareejinta AMT? Waa sababta oo ah usha wareejinta elektaroonigga ah waxay sidoo kale isticmaashaa mabda'a soo-saarista elektaroonigga ah ee usha wareejinta AMT si loogu wareejiyo geerka.
Si kastaba ha ahaatee, waxaa jira farqi u dhexeeya in Micro-CPU-ga lagu hayo substrate-ka iyo in aan mid la haysan.
Haddii substrate-ka (PCB) uu ku qalabaysan yahay Micro-CPU, wuxuu kala saari doonaa koronto kala duwan, wuxuu xaqiijin doonaa qalabkiisa u dhigma, wuxuuna macluumaadka qalabka u dhigma u diri doonaa ECU-ga gaariga qaab gaar ah oo gudbin ah (sida calaamadda CAN). Macluumaadka waxaa hela ECU-yada u dhigma (tusaale ahaan TCM, Xakamaynta Gudbinta) waxaana la farayaa gudbinta inay wareegto. Haddii uusan jirin Micro-CPU oo ku yaal looxa salka (PCB), kabaalka wareejinta elektaroonigga ah laftiisa waxaa loo diri doonaa ECU-ga gaariga iyada oo loo marayo calaamadda siligga si loogu wareejiyo qalabka.
Waxaa la dhihi karaa isticmaalka baarka shift-ka AMT waa tanaasul ku yimid OEM-ka baabuurta ee kharashka wax soo saarka baabuurta ee jaban, kaas oo leh labadaba cabbirka weyn ee baarka shift-ka MT/AT iyo doorashada kicinta elektaroonigga ah. Si kastaba ha ahaatee, doorashada baarka shift-ka elektaroonigga ah kuma koobna cabbirka, sidaa darteed baarka shift-ka elektaroonigga ah hadda waxaa loo sameeyay iyadoo ujeedadu tahay in la yareeyo sidii loogu talagalay. Sidaa darteed, meel bannaan oo dheeraad ah ayaa laga tagi karaa naqshadeynta gaariga. Intaa waxaa dheer, xuduudaha sida usha shift-ka Stroke iyo Operation Force sidoo kale waa la hagaajin karaa marka la barbar dhigo usha shift-ka farsamada, taasoo ka dhigaysa hawlgalku mid raaxo leh darawalka.
Waqtigan xaadirka ah, noocyada Lever-ka elektaroonigga ah ee suuqa yaalla waa sidan soo socota: Nooca Lever-ka, Nooca Rotary/Dial, Nooca Bus-ka Riixa, Nooca Column Lever-ka.
Tusaale ahaan, badhanka wuxuu si toos ah ugu soo laaban karaa qalabka P waxaana ku xiran kara BTSI (BRAKAING TRANSMISSION SHIFT INTERLOCK) ama wuxuu qaadan karaa kor u qaadis madax-bannaan. Nidaamka gaariga, baarka bareegga wuxuu la socdaa barnaamij qaan-gaar ah waa lama huraan, haddii kale wuxuu soo sheegi doonaa oo keliya khaladaad kala duwan, sidaa darteed wuxuu u baahan yahay inuu nadiifiyo barnaamijka. Lugta digaagga BMW ee toosan waxay sidoo kale leedahay shaqada ah inay dib ugu laabato qalabka P ka dib marka la damiyo.
Laga bilaabo bilowgii baarka weyn ee weyn ee farsamada gacanta, ilaa horumarinta baarka yar ee elektaroonigga ah ee fudud oo leh barnaamijkiisa gaarka ah, runtii waxay horumar weyn ka samaysay kuwa dhaadheer iyo kuwa dhaadheer, laakiin ma dhihi karo in isticmaalka baarka elektaroonigga ah uu noqon doono kharash kale oo baabuur ah oo hooseeya, laakiin wuu kordhi doonaa, sidaa darteed OEM-ka hadda jira wali waa naqshadaynta baarka farsamada gacanta. Laakiin iyadoo la kordhinayo baabuurta tamarta cusub, waxaa la saadaalin karaa in usha wareejinta elektaroonigga ah ay si tartiib tartiib ah u noqon doonto midda ugu muhiimsan mustaqbalka.
