Mfundo yogwirira ntchito ya injini yopukuta
Mota yopukutira imayendetsedwa ndi mota. Kuyenda kozungulira kwa mota kumasinthidwa kukhala kuyenda kobwerezabwereza kwa mkono wopukutira kudzera mu njira yolumikizira ndodo, kuti zigwire ntchito yopukutira. Nthawi zambiri, chopukutira chimatha kugwira ntchito polumikiza mota. Posankha giya yothamanga kwambiri komanso yotsika, mphamvu yamagetsi ya mota imatha kusinthidwa, kuti ilamulire liwiro la mota kenako ilamulire liwiro la mkono wopukutira. Mota yopukutira imagwiritsa ntchito kapangidwe ka maburashi atatu kuti ithandize kusintha liwiro. Nthawi yosinthasintha imayendetsedwa ndi relay yosinthasintha. Ntchito yochapira ndi kutulutsa mphamvu ya return switch contact ya mota ndi resistance capacitor ya relay imagwiritsidwa ntchito kupanga wiper sweep malinga ndi nthawi inayake.
Pali giya yaying'ono yolumikizira yomwe ili m'nyumba yomweyi kumbuyo kwa mota ya wiper kuti ichepetse liwiro lotulutsa kufika pa liwiro lofunikira. Chipangizochi chimadziwika kuti wiper drive assembly. Shaft yotulutsa ya msonkhano imalumikizidwa ndi chipangizo chamakina kumapeto kwa wiper, ndipo kugwedezeka kobwerezabwereza kwa wiper kumachitika kudzera mu fork drive ndi spring return.
Chingwe cha rabara cha chotsukira ndi chida chochotsera mvula ndi dothi pagalasi mwachindunji. Chingwe cha rabara cha tsamba chimakanikizidwa pamwamba pagalasi kudzera mu chingwe cha kasupe, ndipo mlomo wake uyenera kufanana ndi ngodya yagalasi kuti ukwaniritse ntchito yofunikira. Nthawi zambiri, pamakhala chogwirira chotsukira chotsukira pa chogwirira cha chosinthira cha magalimoto, chomwe chili ndi magiya atatu: liwiro lotsika, liwiro lapamwamba komanso losasinthasintha. Pamwamba pa chogwirira ndi chosinthira kiyi cha chotsukira. Chosinthira chikakanikizidwa, madzi otsukira amatuluka kuti asambitse galasi ndi chotsukira.
Zofunikira pa khalidwe la injini ya wiper ndi zapamwamba kwambiri. Imagwiritsa ntchito mota ya DC permanent magnet, ndipo injini ya wiper yomwe imayikidwa pagalasi lakutsogolo nthawi zambiri imagwirizanitsidwa ndi gawo la makina a zida za nyongolotsi. Ntchito ya zida za nyongolotsi ndi njira ya nyongolotsi ndikuchepetsa liwiro ndikuwonjezera mphamvu. Shaft yake yotulutsa imayendetsa kulumikizana kwa mipiringidzo inayi, komwe kumasintha kayendedwe kozungulira kosalekeza kukhala kayendedwe ka swing kuchokera kumanzere kupita kumanja.
