Gear mafuta - pamene kusintha ndi kusankha mafuta oyenera kufala Buku ndi kufala basi?

Udindo wa mafuta mu gearbox

Magalimoto amagwiritsa ntchito madzi osiyanasiyana, kuphatikizapo mafuta. Chofala kwambiri ndi mafuta a injini, m'malo mwake nthawi zonse amaonetsetsa kuti galimoto ikuyenda bwino. Mafuta ang'onoang'ono kapena ochulukirapo angayambitse injini kugwidwa ndi kuthamangitsidwa kwazinthu zina. 

Kodi ndizofanana ndi mafuta a gear? Osafunikira. Mafuta mu gearbox amagwira ntchito zingapo, monga:

• kondomu ya munthu zinthu;
• kuchepetsa kukangana;
• kuzizira kwa zigawo zotentha;
• kufewetsa ndi kunyowetsa zida kugwedeza mbali iyi ya galimoto;
• kuchepetsa kugwedezeka;
• chitetezo cha ziwalo zachitsulo ku dzimbiri. 

Kuonjezera apo, mafuta otumizira ayenera kusunga mkati mwa kufalitsa koyera. Mafuta a gear ayenera kufanana ndi momwe galimoto yanu ikufunira. Ndikofunikira ngati idzakhala galimoto yamatauni, kaya idzakhala galimoto yamasewera kapena galimoto yobweretsera. 

Kodi ndikofunikira kusintha mafuta a gearbox? Kodi ndizofunikiradi?

Nthawi zambiri, opanga magalimoto sapereka kusintha kwa mafuta muzotengera zodziwikiratu. Ndiye cholinga chake ndi chiyani? Kodi ndikofunikira kusintha mafuta a gearbox? Amakanika amavomereza kuti mafuta atsopano amatsitsimutsa ndikuzizira bwino. Ndikofunikira kuti ziwalo zonse zopatsirana zizigwira ntchito moyenera. Nthawi zambiri, izi zitha kuthandiza kupewa kulephera kotheka kapena kuwonjezera nthawi yokwera galimoto.

Mafuta otumizira pamanja sangakhale opsinjika ngati mafuta a injini, koma amathanso kukalamba. Mafuta atsopano adzagwira ntchito bwino. Bokosi la gear lidzakhala ndi moyo wautali chifukwa zigawo zake zamkati zimakhala zodzaza bwino komanso zokhazikika.

Mutha kukhala mukudabwa chifukwa chake opanga samalimbikitsa kusintha mafuta a gearbox. Mwina amaganiza kuti galimoto latsopano adzakhala ndi mwini woyamba salinso kuposa kuyembekezera kusintha koyamba kwa madzimadzi ichi kufala.

Kodi kusintha mafuta gearbox?

Kuvomerezeka kosintha mafuta a giya sikungatsutsidwe. Dziwani kuti kusintha koteroko kumafunika kangati. Chifukwa chakuti mafutawo amakwirira zigawo zamkati zomwe zimayenda mosalekeza, moyo wamafutawo umachepa pakapita nthawi. Kusintha kwamafuta ku gearbox tikulimbikitsidwa aliyense 60-120 zikwi. mtunda. Ma gearbox ena okhala ndi ma clutch awiri (double clutch) angafunike kukonzanso pafupipafupi kuposa ena chifukwa cha momwe amagwirira ntchito. Ikhoza kukhala kamodzi pa 40-50 zikwi. mtunda.

Chingakhale chanzeru kusintha mafuta a gear pokhapokha nthawi ya chitsimikizo itatha. Kupanda kutero, kudzipangira nokha m'malo mwa mafuta mu gearbox kudzasokoneza chitsimikizo cha wopanga.

Ndi mafuta ati omwe mungasankhire potumiza pamanja komanso kuti azitumiza zodziwikiratu?

Ngati mwaganiza kusintha chida kufala, muyenera kusankha bwino ntchito madzimadzi. Mafuta otumizira pamanja ndi osiyana ndi mafuta otumizira okha chifukwa amagwira ntchito mosiyana.

Mafuta osankhidwa ayenera kukwaniritsa zofunikira za wopanga galimotoyo. Ma Agents amagawidwa molingana ndi sikelo ya API GL yopangidwa ndi American Petroleum Institute. Mafuta otumizira pamanja ali mumitundu 2, 3, 4 ndi 5. Chofunikanso ndi kalasi ya viscosity, yolembedwa ndi chizindikiro cha SAE pamodzi ndi manambala: 70, 75, 80, 85, 90, 110, 140, 190 ndi 250.

Mafuta opangira ma torque okhala ndi chosinthira ma torque ndi zowongolera kapena magalimoto okhala ndi ma clutch apawiri ayenera kukhala amtundu wina - ATF (Automatic Transmission Fluid). Idzakhala ndi magawo oyenera okhudzana ndi kukhuthala kwake. Kusankhidwa mosamala kwa mafuta otumizira ndikofunikira pakugwira ntchito moyenera kwa njira yonse yotumizira. Ngati musankha mankhwala olakwika, sangayankhe mokwanira ku zipangizo zomwe wopanga amapanga bokosilo. Zambiri zomwe mungasankhe mafuta osankhidwa bwino zimapezeka m'buku la eni ake a galimoto.
