Kwiimoto zanamhlanje, inkqubo encedisayo inikezelwa enika ukunyakaza okukhululekile ngexesha lemvula - i-wiper.Le nkqubo iqhutywa yi-motor geared.Funda konke malunga nale yunithi, iimpawu zayo zoyilo, ukhetho, ukulungiswa kunye nokutshintshwa kwinqaku.
Injongo kunye nemisebenzi ye-wiper gear motor
I-wiper geared motor yimoto yombane enamandla aphantsi edityaniswe nebhokisi yegiya esebenza njengokuqhuba kwizisuli zesithuthi.
Izithuthi kufuneka ziqhutywe kuzo zonke iimeko zemozulu, kubandakanywa ngexesha lemvula yazo zonke iintlobo - imvula kunye nekhephu.Kwakhona, ukusebenza kwemoto, itrektara, ibhasi okanye naziphi na ezinye izixhobo akufanele zichaphazeleke ngokungena kwamanzi kunye nokungcola kwi-windshield.Konke oku kubonelelwa yinkqubo encedisayo efakwe ngaphambili kunye / okanye kwifestile yangasemva - ii-wipers ze-windshield.Ukucoca ngokuthe ngqo iglasi kwenziwa ngamabhulashi akhethekileyo ashukumayo, ukuqhubela phambili okubonelelwa yiyunithi eyakhelweyo ye-electromechanical - i-motor geared.
I-wiper gear motor inemisebenzi emithathu ephambili:
● Wiper blade drive;
● Ukuqinisekisa intshukumo ebuyelanayo yeencakuba zosula;
● Misa iibhrashi kwenye yeendawo ezigqithisileyo xa i-wiper icinyiwe.
Imeko kunye nokusebenza kwe-motor geared ayixhomekanga kuphela ekusebenzeni kwe-wiper, kodwa ekusebenzeni ngokuzithemba nokukhuselekileyo kwesithuthi.Ngoko ke, iyunithi ephosakeleyo kufuneka ilungiswe okanye itshintshwe.Kodwa ngaphambi kokuba uye evenkileni ukuze ufumane injini entsha, kufuneka uqonde ukuyila, ukusebenza kunye neempawu zala macandelo eemoto.
Uyilo, ukusebenza kunye neempawu zeemotor ezilungiselelwe ukusula
Kwiimoto ezininzi zale mihla, kusetyenziswa iinjini zombane zohlobo lweentshulube.Uyilo lweyunithi enjalo lulula kakhulu, lubandakanya iinxalenye ezimbini eziphambili:
● Injini yokuqhuba amandla aphantsi;
● Ibhokisi yegiya ebekwe kwindlu egxunyekwe ngokuqinileyo kwindawo yemoto ecaleni kweshafu yayo.
I-motor yombane idla ngokuba yi-commutator, ngoku ngqo, kumbane wokubonelela nge-12 okanye i-24 V. Ukukhusela iindawo zangaphakathi ze-injini kwiimpembelelo ezimbi zokusingqongileyo (amanzi, uthuli, ukungcola okuhlukeneyo), ityala elitywiniweyo okanye isigqubuthelo esongezelelweyo sokukhusela. iyasetyenziswa.Olu yilo lukuvumela ukuba ubeke i-wiper gear motor kwiindawo zomzimba wemoto ezinokhuseleko oluncinci.
Ibhokisi yegiya luhlobo lwentshulube, olubonelela ngotshintsho kwisantya se-shaft yokuphuma ngaxeshanye kunye nokujikeleza kwe-90-degree ye-torque flow.Ngokwesakhiwo, iibhokisi zegiya ziziindidi ezimbini:
● Ngokuqhutywa ngokuthe ngqo kwesixhobo esiqhutywayo esivela kwimbungu;
● Ngegiya eqhutywayo ngegiya eliphakathi (eliphakathi) ledayamitha encinci.
Ulwakhiwo ngokubanzi lwemoto yegiya yokucima
Kwimeko yokuqala, ibhokisi yegiya inamacandelo amabini kuphela: intshulube eqhagamshelwe kwi-motor shaft kunye negiya eqhutywayo enamazinyo econcave.Kwimeko yesibini, i-gearbox inamacandelo amathathu okanye amane: intshulube eqhagamshelwe kwisixhobo esiphakathi (okanye iigiya ezimbini) ezinobubanzi obuncinci, kunye nesixhobo esiqhutywayo.Umbungu udla ngokuba yintsimbi, i-single-pass, kaninzi usikwa ngokuthe ngqo kwishafti yemoto yombane.Indawo engaphambili yombungu (okanye umngxuma ekusikwe kuwo intshulube) ibekwe kumkhono (isinyithi, i-ceramic) okanye i-bearing, kunye nokubuyisela amandla avela kwi-axial avela kwi-worm, indawo engasemva ye-injini ye-injini iphumle. kwi-thrust bearing ekwisiphelo esingasemva sendlu.
Igiya eqhutywayo yebhokisi yegiya ifakwe kwi-shaft yentsimbi eyodlula ngaphaya kwendlu yebhokisi yegiya, i-crank ixhonywe kwindawo yayo ephumayo, ethi yona idityaniswe ne-wiper trapezoid (i-rod yokudibanisa i-rack kunye neentonga).I-crank, kunye ne-trapezoid, iguqula intshukumo ejikelezayo yegiya ibe yintshukumo ephindaphindayo yeencakuba zosula.
Ibhokisi yegiya ibekwe kwindlu etywiniweyo exhonywe kwizindlu zemoto ukusuka kwicala leshaft yayo.Indlu yebhokisi yegiya ikwathatha izinto zolawulo oluzenzekelayo lwe-wiper:
- Umda wokutshintsha - abafowunelwa bokucima imotor elungiselelwe kwenye yeendawo ezigqithisileyo zeebrashi;
- I-Thermobimetallic fuse yokucima i-injini xa ishushu xa kukho ukuxinana okanye ukugcwala.
Umda wokutshintshwa kwemoto yombane uqinisekisa ukuba iibrashi ziyeke kwenye yeendawo ezigqithiseleyo - kwindawo ephantsi okanye ephezulu, kuxhomekeke kuhlobo lwe-wiper kunye neempawu zoyilo zekhebhu yesithuthi.Olu qhagamshelwano luvulwa yikhamera ekhethekileyo kwi-gear, kwaye ukuvalwa rhoqo kunikezelwa yintwasahlobo.Ukusebenza kokutshintsha umda kuchazwe ngezantsi.
I-fuse ye-thermobimetallic iphinda isetyenziswe, ifakwe kwikhefu kwelinye leentambo zamandla zemoto yombane exhunywe kumnxeba wokutshintsha umda.I-fuse iqinisekisa ukuba isiphaluka sombane wombane wombane sivulwa xa ivaliwe okanye ilayishwe kakhulu ngenxa ye-jamming ye-armature.
Ukuxhoma iiracks (ngokuqhelekileyo iziqwenga ezintathu) zihlala zenziwe kwizindlu zebhokisi yegiya, ngoncedo apho yonke iyunithi ixhonywe ngokuthe ngqo kwinxalenye yomzimba okanye kwisibiyeli sentsimbi (ekuthi, nayo, isebenze njengesiseko sokunyuka. i-wiper trapezoid).Imingxuma yokunyuka iyenziwa kwi-bracket, apho i-rubber okanye i-plastiki bushings ifakwe khona, ibonelela ngokufakela okuqinileyo kweyunithi, kunye nokuthotywa kwe-damping kunye ne-vibrations.I-motor geared ye-wiper yangaphambili ifakwe phantsi okanye ngaphezulu kwe-windshield kwii-niches ezifanelekileyo (umzekelo, kwi-air intake ye-heater), i-wiper yangasemva ifakwe phantsi kwe-trim yomnyango ongasemva okanye ongasemva.Ukudibanisa i-node kwinethiwekhi yombane yemoto, ikhonkco eliqhelekileyo linikezelwa kwi-wire harness okanye kumzimba.

Imoto elungiselelweyo isebenza ngolu hlobo lulandelayo.Xa i-wiper ivuliwe, i-injini yangoku ingena kwi-injini ngokutshintsha umda kunye ne-bimetallic fuse, i-shaft yayo iqala ukujikeleza, kunye ne-gearbox ye-worm, kunye ne-crank kunye ne-trapezoid, inika intshukumo ephindaphindiweyo yeebrashi.Xa i-wiper icinyiwe, i-injini yesekethe yamandla ayivuli kwangoko, kodwa okwangoku nje ikhamera ifikelela kwigiya yonxibelelwano lomda wokutshintsha - kulo mzekelo, iibhrashi ziyeke kwindawo egqithisileyo kwaye zingahambi ngakumbi.Kwenzeka okufanayo xa i-wiper itshintshelwa ekusebenzeni okuphakathi, kodwa emva kokumisa okuthile (kusetwa yi-wiper breaker relay), i-current inikezelwa kwi-motor ngokudlula umda wokutshintshela umda, iibrashi zenza ii-oscillations ezininzi, kwaye ziphinde zime kwakhona. isikhundla esigqithisileyo, ngoko umjikelo uphinda.
Uninzi lweemotor ezilungiselelwe ukusula zineebhokisi zegiya ezinomndilili wegiya we-50: 1, oqinisekisa ukusebenza kweeblades kumjikelo we-5-60 umjikelo (ujingiwe kuwo omabini amacala) ngomzuzu ngeendlela ezahlukeneyo (rhoqo kwaye ziphazamisekile).
Unokukhetha njani ngokufanelekileyo, ukulungisa kunye nokutshintsha i-wiper gear motor
Ukuba i-motor geared ayiphumelelanga, ukusebenza kwe-wiper kuphazamiseka de iglasi ayikwazi ukucocwa ngokupheleleyo.Ukungasebenzi kakuhle kunokubonakaliswa ngeengxolo ezahlukeneyo kunye ne-squeaks evela kwibhokisi yegiya.Ukuchonga uhlobo lokuqhekeka, kuyimfuneko ukujonga indibano, uze uyilungise okanye uyibuyisele kwindibano.Ngokuqhelekileyo, iingxaki zivela kwibhokisi yegiya - ukunxitywa kwegiya kwenzeka kunye nomonakalo kwi-bushings / bearings / thrust bears, kunqabile ukuba kubonakale ukungasebenzi kakuhle kwimoto yombane.Unokuzama ukubuyisela i-gearbox, kodwa ngokunxiba okufanayo kweegiya, kulula ukutshintsha indibano yendibano.
Kuphela i-gearbox motor yodidi olufakwe kwimoto ngumenzi kufuneka ithathelwe indawo.Ukuba oku akunakwenzeka ngenxa yaso nasiphi na isizathu, ngoko unokuzama ukufaka iyunithi yodidi olwahlukileyo okanye imodeli, kodwa ngokuqhelekileyo kule meko kukho ubunzima bofakelo (ekubeni imingxuma yokunyuka kunye nemilinganiselo yamacandelo ayihambelani) kwaye kuhlengahlengiso olulandelayo.Kuyimfuneko ukwenza umsebenzi ngokuhambelana nemiyalelo yokulungiswa kwesithuthi.
Ngokukhetha okuchanekileyo kunye nokutshintshwa kwemoto elungiselelweyo, i-wiper iya kuqala ukusebenza ngaphandle kohlengahlengiso olongezelelweyo, ukubonelela ngokuqhuba kakuhle kuyo nayiphi na imozulu.
