Ezimotweni zanamuhla, kunikezwa uhlelo olusizayo olunikeza ukunyakaza okunethezekile ngesikhathi semvula - i-wiper.Lolu hlelo luqhutshwa yi-motor geared.Funda konke mayelana nale yunithi, izici zayo zokuklama, ukukhetha, ukukhanda nokushintshwa esihlokweni.
Inhloso kanye nemisebenzi ye-wiper gear motor
I-wiper geared motor iyinjini kagesi enamandla aphansi ehlanganiswe no-gearbox osebenza njengokushayela izisusi zezimoto.
Izimoto kufanele zisetshenziswe kuzo zonke izimo zezulu, okuhlanganisa phakathi nemvula yazo zonke izinhlobo - imvula neqhwa.Futhi, ukusebenza kwemoto, ugandaganda, ibhasi nanoma yimuphi omunye umshini akufanele kuthinteke ngokungena kwamanzi nokungcola kwi-windshield.Konke lokhu kunikezwa uhlelo olusizayo olufakwe ngaphambili kanye / noma ifasitela elingemuva - ama-windshield wiper.Ukuhlanza ingilazi ngokuqondile kwenziwa ngamabhulashi akhethekile ahambayo, ukushayela okuhlinzekwa yiyunithi eyakhelwe ngaphakathi ye-electromechanical - i-motor geared.
I-wiper gear motor inemisebenzi emithathu eyinhloko:
● I-Wiper blade drive;
● Ukuqinisekisa ukunyakaza okuhambisanayo kwama-wiper blades;
● Misa amabhulashi kwenye yezindawo ezidlulele kakhulu lapho i-wiper icishiwe.
Isimo kanye nokusebenza kwe-motor geared akuxhomekile kuphela ekusebenzeni kwe-wiper, kodwa ekusebenzeni ngokuzethemba nokuphephile kwemoto.Ngakho-ke, iyunithi enephutha kufanele ilungiswe noma ishintshwe.Kodwa ngaphambi kokuya esitolo ukuze uthole injini entsha ehloselwe, kufanele uqonde ukuklama, ukusebenza nezici zalezi zingxenye zezimoto.
Idizayini, ukusebenza kanye nezici ze-wiper geared motors
Ezimotweni eziningi zesimanje, kusetshenziswa izinjini zikagesi zohlobo lwezimpethu.Ukwakhiwa kweyunithi enjalo ngokuvamile kulula, kuqukethe izingxenye ezimbili eziyinhloko:
● Injini yokushayela enamandla aphansi;
● U-gearbox obekwe endlini ogxunyekwe ngokuqinile endaweni yemoto eceleni komphini wawo.
I-motor kagesi imvamisa i-commutator, yamanje eqondile, ye-voltage yokunikezela ye-12 noma i-24 V. Ukuvikela izingxenye zangaphakathi zenjini emathonyeni amabi emvelo (amanzi, uthuli, ukungcola okuhlukahlukene), ikesi elivaliwe noma isembozo sokuvikela esengeziwe. iyasetshenziswa.Lo mklamo ikuvumela ukuthi ubeke i-wiper gear motor ezindaweni zomzimba wemoto ezinokuvikeleka okuncane.
I-gearbox iwuhlobo lwesikelemu, oluhlinzeka ngokushintsha kwejubane le-shaft yokuphuma kanyekanye nokujikeleza kwe-torque engu-90-degree.Ngokwesakhiwo, ama-gearbox ayizinhlobo ezimbili:
● Ngokushayela okuqondile kwegiya eliqhutshwa isibungu;
● Ngegiya elishayelwa ngamagiya aphakathi (maphakathi) anobubanzi obuncane.
Isakhiwo esijwayelekile se-wiper gear motor
Esimweni sokuqala, i-gearbox iqukethe izingxenye ezimbili kuphela: isibungu esixhunywe ku-motor shaft kanye negiya eliqhutshwayo elinamazinyo angama-concave.Esimweni sesibili, i-gearbox iqukethe izingxenye ezintathu noma ezine: isibungu esixhunywe egiyeni eliphakathi (noma amagiya amabili) we-diameter encane, negiya eliqhutshwayo.Isibungu sivamise ukuba yinsimbi, i-single-pass, imvamisa sisikwa ngqo ku-shaft yenjini kagesi.Ingxenye engaphambili yesibungu (noma i-shaft okusikwe kuyo isibungu) itholakala emkhonweni (insimbi, i-ceramic) noma i-bearing, futhi ukunxephezela amandla e-axial avela ku-worm, ingxenye engemuva ye-shaft yenjini ihlezi. ku-thrust bear etholakala ekugcineni kwezindlu.
Igiya elishayelwayo le-gearbox lifakwe ku-shaft yensimbi edlulela ngale kwendlu ye-gearbox, i-crank ifakwe engxenyeni yayo ephumayo, yona exhunywe ku-wiper trapezoid (i-rod rod rack nezinduku).I-crank, kanye ne-trapezoid, iguqula ukunyakaza kwegiya kube ukunyakaza okuphindaphindayo kwama-wiper blades.
U-gearbox ubekwe endaweni evalekile ebekwe phezu kwendlu yenjini ukusuka eceleni komphini wawo.I-gearbox housing iphinde ifake izinto zokulawula i-wiper okuzenzakalelayo:
- I-Limit switch - othintana nabo bokucisha injini egiyelwe kwesinye sezikhundla ezidlulele zamabhulashi;
- I-Thermobimetallic fuse yokuvala injini uma ishisa uma kuba nokuminyana noma ukulayishwa ngokweqile.
Ukushintsha okulinganiselwe kwemoto kagesi kuqinisekisa ukuthi amabhulashi amisa kwesinye sezikhundla ezimbi kakhulu - ngaphansi noma phezulu, kuye ngohlobo lwe-wiper kanye nezici zokuklama zekhebhu yemoto.Laba othintana nabo bavulwa yikhamera ekhethekile egiyeni, futhi ukuvala njalo kunikezwa isiphethu.Ukusebenza komkhawulo wokushintsha kuchazwe ngezansi.
I-thermobimetallic fuse iyasebenziseka kabusha, ifakwe ekuqhekekeni kwenye yezintambo zamandla zemoto kagesi ezixhunywe kothintana nomshini wokushintsha umkhawulo.I-fuse iqinisekisa ukuthi umjikelezo wokuphakelwa kwamandla wemoto kagesi uyavuleka uma ivaliwe noma ilayishwe kakhulu ngenxa yokuminyana kwe-armature.
Ama-racks okufakwayo (imvamisa izingcezu ezintathu) avame ukwenziwa ku-gearbox yezindlu, ngosizo lapho yonke iyunithi ifakwa ngqo engxenyeni yomzimba noma kubakaki bensimbi (okubuye kube yisisekelo sokukhweza. i-wiper trapezoid).Izimbobo ezifakwayo zenziwa kubakaki, lapho kufakwa khona i-rubber noma i-plastic bushings, ehlinzeka ngokufakwa okuqinile kweyunithi, kanye nokuthuthumela okumanzi nokudlidliza.I-motor geared ye-wiper yangaphambili ifakwe ngaphansi noma ngaphezulu kwe-windshield ezindaweni ezifanele (isibonelo, ekungeneni komoya we-heater), i-wiper yangemuva ifakwe ngaphansi kwe-trim yomnyango ongemuva noma ongemuva.Ukuze uxhume i-node kunethiwekhi kagesi yemoto, isixhumi esijwayelekile sinikezwa kuhhanisi lezintambo noma emzimbeni.

i-wiper gear motor Shaft side wiper gear motor
I-motor geared isebenza kanje.Lapho i-wiper ivuliwe, i-current ingena enjini ngokusebenzisa i-switch limit kanye ne-bimetallic fuse, i-shaft yayo iqala ukujikeleza, futhi i-gearbox ye-worm, kanye ne-crank ne-trapezoid, inikeza ukunyakaza okuphindaphindiwe kwamabhulashi.Lapho i-wiper icishiwe, isifunda samandla enjini asivuli ngokushesha, kodwa kuphela ngesikhathi ikhamera ifinyelela igiya loxhumana nabo be-switch limit - kulokhu, amabhulashi ayeka endaweni ephakeme futhi angaqhubeki phambili.Okufanayo kwenzeka lapho i-wiper idluliselwa ekusebenzeni ngezikhathi ezithile, kodwa ngemva kokumiswa okuthile (kusethwa yi-wiper breaker relay), i-current inikezwa ku-motor ngokudlula umkhawulo wokushintsha, amabhulashi enza ama-oscillations ambalwa, futhi aphinde amise isikhundla esiphezulu, khona-ke umjikelezo uphinda.
Iningi lama-motor geared wiper anama-gearbox anesilinganiso segiya esijwayelekile esingu-50: 1, esiqinisekisa ukusebenza kwama-blades ngemvamisa yemijikelezo engu-5-60 (ukushwibeka kuzo zombili izinkomba) ngomzuzu ngezindlela ezahlukahlukene (njalo futhi ngezikhathi ezithile).
Ungakhetha kanjani kahle, ulungise futhi ushintshe i-wiper gear motor
Uma i-motor geared ihluleka, ukusebenza kwe-wiper kuphazamiseka kuze kube yilapho ingilazi ingakwazi ukuhlanzwa ngokuphelele.Ukungasebenzi kahle kungabonakala ngemisindo ehlukahlukene kanye nokukhala okuvela ku-gearbox.Ukukhomba uhlobo lokuqhekeka, kuyadingeka ukuhlola umhlangano, bese ulungisa noma uwufake esikhundleni emhlanganweni.Imvamisa, izinkinga ziphakama ku-gearbox - ukugqokwa kwegiya kwenzeka kanye nokulimala kwama-bushings / ama-bearings / thrust bears, ukungasebenzi kahle okungajwayelekile kubonwa ku-motor kagesi.Ungazama ukubuyisela u-gearbox, kodwa ngokugqokwa komfaniswano wamagiya, kulula ukufaka esikhundleni somhlangano.
I-gearbox motor kuphela yohlobo olufakwe umenzi emotweni okufanele ithathwe ukuze ishintshwe.Uma lokhu kungenakwenzeka nganoma yisiphi isizathu, ungazama ukufaka iyunithi yohlobo oluhlukile noma imodeli, kodwa ngokuvamile kulokhu kuba nobunzima ekufakeni (njengoba izimbobo ezikhulayo nobukhulu bezingxenye azifani) futhi ekulungiseni okulandelayo.Kuyadingeka ukwenza umsebenzi ngokuhambisana nemiyalelo yokulungisa imoto.
Ngokukhetha okulungile nokushintshwa kwe-motor geared, i-wiper izoqala ukusebenza ngaphandle kokulungiswa okwengeziwe, inikeze ukushayela okunethezekile kunoma yisiphi isimo sezulu.
