Kunoma iyiphi imoto yanamuhla kukhona i-wiper, lapho ukushayela kwamabhulashi kwenziwa khona ngendlela elula - i-trapezoid.Funda konke mayelana ne-wiper trapezoid, izinhlobo zabo ezikhona, ukuklama kanye nesimiso sokusebenza, kanye nokukhetha okulungile nokushintshwa kwalezi zingxenye kulesi sihloko.
Iyini i-wiper trapezoid?
I-Wiper trapezoid iyi-wiper drive, uhlelo lwezintambo nama-levers oluhlinzeka ngokunyakaza okuphindaphindiwe kwama-wiper blades ku-windshield noma ingilazi yomnyango wangemuva wezimoto.
Ezimotweni, amabhasi, ogandaganda nezinye izinto zokusebenza, kuhlala kune-wiper - uhlelo olusizayo oluhlanza i-windshield emanzini nokungcola.Izinhlelo zanamuhla ziqhutshwa ngogesi, futhi ukudluliswa kwamandla kusuka ku-motor kagesi kuya emabhulashini kwenziwa ngokusebenzisa uhlelo lwezintambo kanye nezinsimbi ezibekwe ngaphansi kwengilazi - i-wiper trapezoid.
I-wiper trapezoid inemisebenzi eminingi:
● Shayela ama-wiper blades enjini kagesi;
● Ukwakhiwa kokunyakaza okuhambisanayo kwamabhulashi (noma amabhulashi) anobude obudingekayo;
● Kuma-wiper anama-blade amabili nantathu, iqinisekisa ukunyakaza okuvumelanayo kwama-blades eduze kwama-trajectories afanayo noma ahlukene wensingo ngayinye.
I-wiper trapezoid eqinisekisa ukunyakaza "kwe-wipers" engilazini nge-amplitude edingekayo (ububanzi) kanye ne-synchrony, futhi ukungasebenzi kahle kwalesi yunithi ngokwengxenye noma kuphazamisa ngokuphelele ukusebenza kwalo lonke uhlelo.Mayelana nokuwohloka, i-trapezoid kufanele ilungiswe noma ishintshwe emhlanganweni, kodwa ngaphambi kokuqala ukulungisa, kufanele uqonde izinhlobo ezikhona zalezi zindlela, ukuklama kwazo kanye nesimiso sokusebenza.
Zonke izimoto, ogandaganda nemishini eyahlukene ifakwe ama-relay-regulators.Ukungasebenzi kahle kwalolu phiko kuphazamisa ukusebenza kwalo lonke uhlelo lukagesi, kwezinye izimo lokhu kungaholela ekuwohlokeni kwemishini kagesi nemililo.Ngakho-ke, umlawuli ongalungile kufanele ashintshwe ngokushesha ngangokunokwenzeka, futhi ukuze kukhethwe kahle ingxenye entsha, kuyadingeka ukuqonda izinhlobo ezikhona, ukuklama kanye nesimiso sokusebenza kwabalawuli.
Izinhlobo, ukwakheka kanye nesimiso sokusebenza kwe-wiper trapezoid
Okokuqala, wonke ama-trapezoid angahlukaniswa ngezinhlobo ezintathu ngokuya ngenani lamabhulashi:
● Okokusula ngebhulashi elilodwa;
● Okwama-wiper ane-double blade;
● Okwamawipha anezinhlamvu ezintathu.

Ngesikhathi esifanayo, ukushayela kwebhulashi elilodwa akukwazi ukubizwa ngokuthi i-trapezoid, ngoba ezimweni eziningi yakhiwe kuphela ku-motor kagesi nge-gearbox ngaphandle kwezinduku ezengeziwe noma ngenduku eyodwa.Futhi ama-trapezoid amabhulashi amabili nantathu anomshini ofanayo ngokuyisisekelo futhi ahluke kuphela ngenani lezinduku.
Ngokulandelayo, ama-trapezoid amabhulashi amabili nantathu angahlukaniswa abe izinhlobo ezimbili ngokuya ngendawo lapho i-motor kagesi ixhumeke khona:
● I-Symmetrical - i-motor kagesi itholakala phakathi nendawo ye-trapezoid (phakathi kwamabhulashi), iqinisekisa ukunyakaza kokubili kwe-brush rods ngesikhathi esisodwa;
● I-Asymmetric (i-asymmetrical) - injini kagesi ibekwe ngemuva kwe-trapezoid, ihlinzeka ngokushayela kwayo nge-thrust yangemuva eyengeziwe.

Namuhla, ama-trapezoid asymmetric avame kakhulu, anedivayisi elula kakhulu.Ngokuvamile, isisekelo sokuklama sakhiwe izinduku ezimbili ezinamaphiko, ku-hinge phakathi kwezinduku futhi ekupheleni kwesinye sazo kukhona ama-leashes - ama-levers anobude obuncane, axhunywe ngokuqinile kuma-roller ama-levers shayela.Ngaphezu kwalokho, i-leash ephakathi ingafakwa ngokuqondile ekuhlanganyeleni kwe-hinge yezinduku ezimbili (kulokhu, izinduku ezimbili ne-leash ziphuma endaweni eyodwa), noma zixhume izinduku ngamahinge amabili, futhi zithwale i-roller engxenyeni ephakathi.Kuzo zombili izimo, ama-leashes ahambisana nezinduku, okuqinisekisa ukuphambuka kwawo ngesikhathi sokunyakaza okuphindaphindiwe kwezinduku.
Ama-roller ayenziwe ngendlela yezinsimbi ezimfushane zensimbi, phezulu lapho izintambo zinqunywa noma izikhala zinikezwa ukulingana okuqinile kwe-wiper blade levers.Ngokuvamile, ama-roller atholakala kuma-bearings angenalutho, wona, aphethwe ngamabakaki anezimbobo zokubopha.Ngokuphela kwamahhala kwe-thrust yesibili, i-trapezoid inamathiselwe ku-gearbox yemoto kagesi, enomklamo olula kakhulu - ngesimo se-crank ebekwe ngqo ku-motor shaft, noma efakwe egiyeni legiya lokunciphisa izikelemu. .I-motor kanye ne-gearbox kagesi ihlanganiswe ibe yiyunithi eyodwa, lapho kungatholakala khona ukushintshwa komkhawulo, okuqinisekisa ukuthi amabhulashi ame endaweni ethile lapho i-wiper icishiwe.
Izinduku, ama-leashes, ama-roller kanye nabakaki bemishini yenziwa ngokugxiviza kusuka eshidini lensimbi noma ngokugoba izikhala ze-tubular, ezinokuqina okuphezulu kokugoba.Ama-hinges enziwe ngesisekelo sama-rivets noma ama-caps, ama-plastic bushings kanye nama-caps okuzivikela afakwe ezindaweni zokuhlanganisa ama-hinge, ukugcotshwa okwengeziwe kunganikezwa.Izimbobo ze-hinge emigqeni ngokuvamile ziyi-oval ukuqinisekisa umzila odingekayo wamabhulashi.
I-wiper drive isebenza kanje.Lapho i-wiper ivuliwe, i-crank iguqula ukunyakaza okujikelezayo kwe-motor shaft ibe ukunyakaza okuphindaphindayo kwezinduku ze-trapezoid, ziyachezuka endaweni yazo emaphakathi ziye kwesokudla nakwesokunxele, futhi ngemichilo iphoqa ama-roller ukuthi ajikelezise endaweni ethile. i-angle - konke lokhu kuholela ekudlidlizeni kwesici kwama-levers namabhulashi atholakala kuwo.
Ngokufanayo, ama-trapezoids ama-wiper amabhulashi amathathu ahlelwe, afaka kuphela induku yesithathu nge-leash, ukusebenza kwesistimu enjalo akufani nalokho okusanda kuchazwa.
I-trapezoid ye-Symmetrical nayo iyisistimu yezinduku ezimbili eziveziwe kanye nezintambo, kodwa ama-leashes atholakala emaphethelweni ahlukene wezinduku, futhi i-leash eyengeziwe noma i-lever ifakwe ku-hinge phakathi kwezinduku ukuxhuma ku-gearbox ye-motor kagesi.Ukwandisa ukuqina nokwenza lula ukufakwa, ubakaki ungafakwa ku-trapezoid enjalo - ipayipi elixhuma i-leashes yebhulashi, engxenyeni emaphakathi lapho kungaba khona isiteji sokufaka i-motor kagesi nge-gearbox.Uhlelo olunjalo aludingi ukuqiniswa okuhlukene kwama-leashes noma ama-roller, okwandisa ukunethezeka kwawo nokuthembeka uma kuqhathaniswa nezinye izinhlobo ze-trapezoid.
I-Wiper trapezoids ingatholakala ngaphansi noma ngaphezu kwe-windshield endaweni ekhethekile (igumbi) elakhiwe izingxenye zomzimba.Abakaki abanama-lever roller ebhulashi bafakwa emzimbeni (flush) kusetshenziswa izikulufu ezimbili noma ezintathu (noma amabhawudi), kanti umkhondo we-roller uvamise ukuvalwa ngezindandatho zenjoloba noma amakepisi / amakhava okuzivikela.Injini kagesi eno-gearbox ifakwa ngqo esithweni somzimba noma kubakaki abaqhamuka ne-trapezoid.Ngokufanayo, ama-windshield we-windshield e-single-brush yengilazi yangemuva afakiwe.
Indlela yokukhetha futhi esikhundleni se-wiper trapezoid
Ngesikhathi sokusebenza kwe-wiper, izingxenye ze-trapezoid zayo ziyaguga, ziwohloke noma zigoqe - ngenxa yalokho, wonke umshini uyeka ukwenza imisebenzi yawo ngokujwayelekile.Ukungasebenzi kahle kwe-trapezoid kuboniswa ukunyakaza okunzima kwamabhulashi, ukuma kwawo ngezikhathi ezithile kanye nokukhishwa kwe-desynchronization, futhi konke lokhu kungase kuhambisane nomsindo owandayo.Ukukhomba ukungasebenzi kahle, kuyadingeka ukuhlola i-trapezoid, futhi uma ukuwohloka kungenakuqedwa, buyisela umshini.
I-trapezoid enezicucu ezintathu
Yilawo ma-trapezoid kuphela aklanyelwe ngokukhethekile kule moto okufanele athathwe ukuze ashintshwe - lena yindlela kuphela yokuqinisekisa ukuthi i-wiper ingafakwa ngokujwayelekile futhi izosebenza ngokuthembekile.Kwezinye izimo, kuvunyelwe ukusebenzisa ama-analogue, noma kunjalo, ngisho nasezimotweni zemodeli efanayo yeminyaka ehlukene yokukhiqiza, izindlela zingahluka ekuqinisweni nasekuklanyweni kwezingxenye ngazinye (okuhlotshaniswa nokushintsha kwesakhiwo somzimba, indawo yengilazi, njll.).
Ukushintshwa kwe-trapezoid kufanele kwenziwe ngokuhambisana nemiyalelo yokulungiswa kwemoto.Imvamisa, ukudiliza yonke indlela, kwanele ukususa izinsimbi zebhulashi, bese uqaqa izibophelelo zamabakaki ama-roller noma ubakaki abavamile, bese ususa umhlangano we-trapezoid nge-motor kanye ne-gearbox.Kwezinye izimoto, i-trapezoid kanye ne-motor kagesi zisuswa ngokuhlukana, futhi ukufinyelela kwezibophelelo zabo kwenziwa ezinhlangothini ezahlukene ze-niche ngaphansi kwe-windshield.Ukufakwa komshini omusha kwenziwa ngokulandelana, futhi kungase kudingeke ukuthi kugcotshwe ezinye izingxenye.Lapho wenza ukufakwa, kuyadingeka ukuqapha indawo efanele yezinduku, ama-leashes nezinye izingxenye ze-trapezoid, ngaphandle kwalokho ukusebenza komshini kungase kuphazamiseke.Uma i-trapezoid ikhethiwe futhi ifakwe ngendlela efanele, i-wiper izosebenza ngokuthembekile, igcine ukuhlanzeka nokungafihli kwengilazi kuzo zonke izimo.
