Ponena za ndodo yosinthira, tiyenera kulankhula za kukula kwachangu kwa ndodo yosinthira zamagetsi, mitundu ina ya ndodo yosinthira, ndi kufotokozera kwina mwatsatanetsatane.
Tsopano pali mitundu inayi ya ma shifter pamsika. Kuchokera m'mbiri ya chitukuko, ndi awa: MT (ManualTransmissionShifter, manual shift lever) -> AT (AutomaticTransmissionTransmissionShifter, Automatic gear lever) kupita ku AMT (AutomatedMechanicalTransmissionShifter, semi-automatic gear lever), GSM (GearShiftModule, kapena SBW = ShiftByWire, electronic gear lever)
Popeza ndodo yosinthira ya MT ndi AT kwenikweni ndi kapangidwe ka makina, ilibe ubale wokwanira ndi ndodo yosinthira yamagetsi. Chifukwa chake, monga tafotokozera poyamba, mzere wina umapangidwa.
Tisanalankhule za chosinthira magetsi, tiyeni tikambirane za chosinthira cha AMT.
Chowongolera magiya a AMT sichimangolandira kapangidwe ka makina a MT/AT bwino, komanso chimagwiritsa ntchito electromagnetic induction kuti chizindikire malo a magiya kapena kusawazindikira, komanso zizindikiro zotulutsa za malo osiyanasiyana a magiya. Mwachidule, chowongolera magiya a AMT kapena gawo lake lolumikizirana lili ndi maginito okhala ndi ma poles abwino ndi oipa kumpoto ndi kum'mwera, ndipo amasintha malo ake kudzera m'malo osiyanasiyana a magiya. Bolodi loyambira (PCB) lokhala ndi SENSOR IC pa chowongolera magiya cha AMT limapanga induction yamaginito ku maginito m'malo osiyanasiyana ndipo limatulutsa mafunde osiyanasiyana. Gawo la purosesa yagalimoto lidzasuntha magiya ogwirizana ndi mafunde kapena zizindikiro zosiyanasiyana.
Kuchokera pamalingaliro a kapangidwe kake, ndodo yosinthira ya AMT ndi yovuta kwambiri kuposa ndodo yosinthira ya MT/AT, ukadaulo wakwera, mtengo wa unit imodzi ndi wokwera mtengo, koma kwa OEM yagalimoto, kugwiritsa ntchito ndodo yosinthira ya AMT, bola ngati kusintha pang'ono, ndiko kuti, kungagwiritse ntchito kwambiri njira yamagetsi ya MT, kotero mtengo wonse wagalimoto udzakhala wotsika.
Chifukwa chiyani AMT shift lever? Chifukwa chakuti electronic shift rod imagwiritsanso ntchito mfundo ya electromagnetic induction ya AMT shift rod poyendetsa magiya.
Komabe, pali kusiyana pakati pa kukhala ndi Micro-CPU pa substrate ndi kusakhala nayo.
Ngati substrate (PCB) ili ndi Micro-CPU, imasiyanitsa magetsi osiyanasiyana, kutsimikizira giya yake yofanana, ndikutumiza zambiri za giya yofanana ku ECU yagalimoto munjira inayake yotumizira (monga chizindikiro cha CAN). Zambirizo zimalandiridwa ndi ma ECU ogwirizana (monga TCM,TransmissionControl) ndipo giyayo imalangizidwa kuti isinthe. Ngati palibe Micro-CPU pa bolodi loyambira (PCB), lever yosinthira yamagetsi yokha idzatumizidwa ku ECU yagalimoto kudzera mu chizindikiro cha waya kuti isinthe giyayo.
Tinganene kuti kugwiritsa ntchito AMT shift bar ndi njira yabwino kwambiri yopangira magalimoto otsika mtengo, yomwe ili ndi kukula kwakukulu kwa MT/AT shift bar komanso kusankha electromagnetic induction. Komabe, kusankha electronic shift bar sikungodalira kukula, kotero electronic shift bar pakadali pano yapangidwa ndi cholinga cha miniaturization ngati maziko. Chifukwa chake, malo ochulukirapo angasiyidwe mu kapangidwe ka galimoto. Kuphatikiza apo, magawo monga shift rod Stroke ndi Operation Force amathanso kukonzedwa bwino poyerekeza ndi mechanical shift rod, zomwe zimapangitsa kuti ntchitoyo ikhale yabwino kwa dalaivala.
Pakadali pano, mitundu ya Lever yamagetsi pamsika ndi iyi: Mtundu wa Lever, Mtundu wa Rotary/Dial, Mtundu wa Push Switch, Mtundu wa Lever ya Column.
Mwachitsanzo, chogwiriracho chimatha kubwerera ku giya la P ndikutsekedwa ndi BTSI (BRAKING TRANSMISSION SHIFT INTERLOCK) kapena kukwera pa autonomous liftoff. Mu dongosolo la galimoto, braking bar imabwera ndi pulogalamu yokhwima ndikofunikira, apo ayi imangonena zolakwika zosiyanasiyana, kotero imafunika kukonza mapulogalamu. Mwendo wa nkhuku wa BMW womwe uli ndi ndodo yolunjika ulinso ndi ntchito yobwerera ku giya la P ukatha kuzimitsa.
Kuyambira pachiyambi cha kukula kwakukulu, makina osinthira magetsi akuluakulu, mpaka kupanga makina osinthira magetsi opepuka komanso opepuka okhala ndi pulogalamu yakeyake, kwapita patsogolo kwambiri pamakina osinthira magetsi aatali ndi aatali, koma sitinganene kuti kugwiritsa ntchito makina osinthira magetsi kudzakhala kotsika mtengo, koma kudzakwera, kotero OEM yomwe ilipo pakadali pano idakali kapangidwe ka makina osinthira magetsi. Koma ndi kuwonjezeka kwa magalimoto atsopano amphamvu, zitha kunenedweratu kuti makina osinthira magetsi pang'onopang'ono adzakhala otchuka mtsogolo.
