Ezimotweni ezinezinhlelo zokubhuleka ezisebenza nge-hydraulically, i-brake fluid igcinwa esitsheni esikhethekile - i-reservoir ye-master brake cylinder.Funda konke mayelana amathangi e-GTZ, ukwakheka kwawo, izinhlobo ezikhona nezici, kanye nokukhetha nokushintshwa kwalezi zingxenye esihlokweni.
Inhloso nemisebenzi yethangi le-GTZ
Ithangi le-GTZ (ithangi le-cylinder master brake, ithangi lokunweba le-GTZ) liyingxenye ye-master brake cylinder yesistimu ye-brake eqhutshwa ngamanzi;isitsha sokugcina uketshezi lwamabhuleki bese ulunikeza i-GTZ ngesikhathi sokusebenza kwesistimu yamabhuleki.
Izimoto ezithwala abantu, amaloli ezentengiselwano kanye namaloli amaningi aphakathi nendawo afakwe amasistimu amabhuleki esondo asebenza ngogesi.Ngokuvamile, uhlelo olunjalo luqukethe i-brake master cylinder (GTZ), nge-vacuum noma i-pneumatic amplifier ehambisana ne-brake pedal, namasilinda amabhuleki asebenzayo (RTC) kumabhuleki amasondo axhunywe ku-GTZ ngohlelo lwamapayipi.I-brake fluid ekhethekile isebenza ohlelweni, okuqinisekisa ukudluliswa kwamandla kusuka ku-GTZ kuya ku-RTC futhi, ngaleyo ndlela, amabhuleki asetshenziswa.Ukugcina ukunikezwa kwamanzi ohlelweni, kusetshenziswa isici esikhethekile - indawo yokugcina isilinda ye-brake master.
Umdwebo ojwayelekile wesistimu yamabhuleki esebenza nge-hydraulically actuated
Ithangi le-GTZ lixazulula imisebenzi eminingana ebalulekile:
● Isebenza njengesitsha sokugcina uketshezi lwamabhuleki;
● Inxephezela ukwanda okushisayo koketshezi;
● Inxephezela ukuvuza okuncane koketshezi ohlelweni;
● Ihlinzeka ngokunikezwa kwamanzi ku-GTZ ngesikhathi sokusebenza kohlelo;
● Yenza imisebenzi yesevisi - iqapha izinga loketshezi lwamabhuleki nokugcwaliswa kwalo, okubonisa ukwehla okuyingozi kwezinga loketshezi.
Ithangi le-GTZ libaluleke kakhulu ekusebenzeni okujwayelekile kwesistimu yamabhuleki, ngakho-ke ukuphepha kwayo yonke imoto.Ngakho-ke, uma kwenzeka noma yikuphi ukungasebenzi kahle, le ngxenye kufanele ilungiswe noma ishintshwe ngesikhathi esifanele.Ukuze wenze ukushintshwa okulungile, kufanele uqonde izinhlobo ezikhona zamathangi e-GTZ nezici zawo.
Izinhlobo, ukwakheka kanye nezici zamathangi e-GTZ
Amathangi e-GTZ asetshenziswa njengamanje ahlukaniswe ngamaqembu amabili amakhulu:
● Isigaba esisodwa;
● Izigaba ezimbili.
Ithangi le-GTZ elinesigaba esisodwa
Ithangi le-GTZ elinezigaba ezimbili
Amathangi anesigaba esisodwa afakwe kuzo zombili izingxenye ze-GTZ zesigaba esisodwa kanye nezigaba ezimbili zamaloli nezimoto.Amasilinda esigaba esisodwa ahlanganiswe ne-pneumatic noma vacuum brake booster asetshenziswa emalolini aphakathi nendawo, angaba amabili awo (i-GTZ eyodwa yama-axle contours yangaphambili nangemuva) noma amathathu (i-GTZ eyodwa ye-axle contour yangaphambili neyodwa isondo ngalinye elingemuva).Ngakho, emotweni enjalo kungase kube amathangi amabili noma amathathu single-section.
Kwezinye izimoto ezifuywayo (inani le-UAZ ne-GAZ onobuhle), i-GTZ enezigaba ezimbili ezinamathangi e-single-section asetshenziswa, ngayinye esebenza esigabeni sayo futhi ayixhunyiwe kwenye.Kodwa-ke, lesi sixazululo sinezingqinamba eziningi, kufaka phakathi ubunzima besistimu kanye nokwehla kokuthembeka kwalo.Ngakolunye uhlangothi, ukuba khona kwamathangi amabili kuqinisekisa ukusebenza okuzimele kwe-circuits yesistimu ye-brake, ngakho-ke, uma ukuvuza kwe-fluid kusuka kumjikelezo owodwa, okwesibili kuzohlinzeka ikhono lokulawula imoto.
Amathangi anezigaba ezimbili afakwe kuphela ku-GTZ enezigaba ezimbili zezimoto namaloli.Amathangi anjalo anobukhulu obunyukile kanye nokufakwa okubili kokuxhuma ezigabeni zesilinda.Kuzo zonke izimoto ezine-GTZ enezigaba ezimbili, kufakwe ithangi elilodwa elinezigaba ezimbili.Amathangi anezigaba ezimbili enza kube lula ukuklama kohlelo lonke futhi anikeze ukudlula uketshezi phakathi kwamasekethe, okuqeda ukwehluleka komunye wabo.
Ngokwesakhiwo, wonke amathangi e-GTZ alula futhi ahluke ngemininingwane kuphela.Amathangi ayipulasitiki (imvamisa enziwe ngepulasitiki emhlophe eguquguqukayo, okwenza kube lula ukulandelela izinga le-liquid), ucezu olulodwa noma lwenziwe ngama-halves amabili okuphonswa, engxenyeni engenhla kukhona intamo yokugcwalisa enentambo noma ye-bayonet, evalwe nge isivalo, engxenyeni engezansi kukhona okokufakwayo.Emathangeni amaningi, okokufakwayo kubunjwa kusuka kupulasitiki, kodwa emalolini amathangi anengxenye eyodwa, ukufakwa kwensimbi okufakwe intambo kuvame ukusetshenziswa.Eceleni kungase kube nefasitela elikhanyayo elinamamaki wezinga eliphezulu nelincane le-liquid.Kwezinye izimo, izinsimbi ezengeziwe zinikezwa - amabakaki noma ama-eyelets.Emathangeni e-GTZ anezigaba ezimbili, ukuhlukaniswa kobude obuphansi kutholakala phakathi kwezigaba, okuvimbela ukugeleza okuphelele koketshezi kusuka engxenyeni eyodwa kuya kwesinye lapho imoto inqoba imithambeka noma lapho ushayela ezindaweni ezingalingani zomgwaqo.
Amathangi angaba nokufakwa okukodwa, okubili noma okuthathu.Ukufakwa okukodwa kwenziwa emathangini e-GTZ esigaba esisodwa, futhi amabili nantathu emathangini anezigaba ezimbili, ukufakwa kwesithathu kungasetshenziswa ukunikeza uketshezi kusilinda se-hydraulic clutch drive.
Izinhlobo ezimbili zamapulaki zisetshenziselwa ukuvala ithangi:
● Evamile enamavalvu akhelwe ngaphakathi;
● Ngamavalvu kanye nenzwa yezinga le-liquid.
Ukuklama nokufakwa kwethangi le-GTZ
Amapulaki avamile anama-valve okulinganisa ukucindezela ku-reservoir (ukungenisa umoya ongaphandle) kanye nokucindezela kokukhulula lapho kushisa noma kunoketshezi oluningi ohlelweni.Kumapulaki ohlobo lwesibili, ngaphezu kwama-valve, inzwa yezinga le-liquid yohlobo lwe-float yakhelwe ngaphakathi, ixhunywe kusibonisi kudeshibhodi.Inzwa iyinzwa yomkhawulo, iqalwa lapho izinga le-liquid lehla ngaphansi komkhawulo othile, livala isifunda sesibani esiyisixwayiso esihambisanayo.
Ukufakwa kwamathangi kungenziwa ngezindlela ezimbili:
● Ngqo emzimbeni we-GTZ;
● Hlukanisa ne-GTZ.
Esimweni sokuqala, ithangi elinokufakwa kwalo ngokuvala ama-rubber bushings lifakwe emigodini engxenyeni engenhla yecala le-GTZ, izinsimbi ezengeziwe noma amabakaki angasetshenziselwa ukulungiswa okuthembekile. indawo ekahle egumbini lenjini noma kwenye indawo, futhi ukuxhumana ne-GTZ kwenziwa kusetshenziswa amapayipi aguquguqukayo.I-tank ixhunywe kubakaki bensimbi ngama-clamps noma izikulufa, ama-hoses aboshwe ngama-clamps.Isixazululo esifanayo singatholakala kwezinye izimoto zasekhaya, kuhlanganise Vaz-2121.
Ithangi le-GTZ lokubekwa ngokwehlukana nesilinda
I-GTZ efakwe ithangi
Kunoma yikuphi, ikhetha indawo ye-reservoir lapho i-brake fluid ingageleza ngamandla adonsela phansi ku-brake master cylinder, iqinisekisa ukusebenza okuvamile kwalo lonke uhlelo ezimweni ezihlukahlukene.
Indlela yokukhetha nokufaka esikhundleni se-brake master cylinder reservoir
Amathangi e-GTZ alula futhi anokwethenjelwa, kodwa angakwazi ukwehluleka ngenxa yokuchayeka ezindaweni ezinolaka, imithelela yemishini neyokushisa - noma yikuphi ukuqhekeka, ukuphuka kokufakwa noma ukuwohloka kwamandla okulungiswa kwepulaki kungaholela ekuwohlokeni kwamabhuleki kanye nesimo esiphuthumayo.Ngakho-ke, ithangi kufanele lihlolwe njalo (ngokugcinwa okuhleliwe kwesistimu ye-brake), futhi uma kutholakala ukungasebenzi kahle, shintsha umhlangano.
Ukuze ulishintshe, kufanele uthathe ithangi le-GTZ kuphela lohlobo nemodeli enconywe umenzi wemoto.Ezimotweni ezifuywayo, kulula ukuthola amathangi, njengoba eziningi zazo zisebenzisa izingxenye ezihlangene, izimoto ezenziwe kwamanye amazwe, udinga ukusebenzisa amathangi kuphela ngokuhambisana nezinombolo zabo zekhathalogi.Ngesikhathi esifanayo, kunconywa ukuthenga ama-bushings, ama-hoses (uma ekhona) kanye nezinsimbi.
Ukushintshwa kwethangi kufanele kwenziwe ngokuhambisana nemiyalelo yokulungisa le modeli yemoto ethile.Kodwa ngokuvamile, i-oda lomsebenzi imi kanje:
1.Susa uketshezi ethangini (kunconywa ukusebenzisa isirinji enkulu noma isibani);
2.Uma kukhona okokufaka isilinda esiyinhloko se-clutch, nqamula ipayipi ethangini bese ulibeka ukuze uketshezi lungaphumi kulo;
3.Uma kukhona i-tank fastening, yisuse (susa izikulufu, susa i-clamp);
4.Khipha ithangi, uma linezigaba ezimbili, lisuse emigodini ngamandla esandla, uma liyingxenye eyodwa, lisuse ekufakeni okufakwe imicu;
5.Hlola ama-bushings, uma wonakalisiwe noma aqhekekile, faka amasha, ngemva kokuhlanza indawo yokufakwa kwawo kanye nengxenye engenhla yomzimba we-cylinder;
6.Faka ithangi elisha ngokulandelana.
Lapho umsebenzi usuqedile, kufanele ugcwalise uketshezi lwamabhuleki bese umpompa uhlelo ukuze ukhiphe amabhamuza omoya.Ngemva kokupompa, kungase kudingeke ukugcwalisa uketshezi ezingeni elidingekayo elikhonjiswe ethangini.Ngokukhetha okulungile kwethangi nokushintshwa kwayo okufanele, isistimu ye-brake yemoto izosebenza kahle futhi inokwethenjelwa kunoma yiziphi izimo.
