Ukulawula ukuhanjiswa okunethezekile nokungakhathali ezimotweni zanamuhla, kusetshenziswa i-hydraulic clutch drive, enye yezindima eziyinhloko edlalwa yi-master cylinder.Funda nge-clutch master cylinder, izinhlobo zayo, ukwakheka nokusebenza, ukukhetha okulungile nokushintshwa kulesi sihloko.
Iyini i-clutch master cylinder?
I-Clutch master cylinder (GVC) - iyunithi ye-hydraulic drive yokuvula nokuvala i-clutch yama-transmissions alawulwa ngesandla (ama-manual transmissions);I-hydraulic cylinder eguqula amandla asuka emlenzeni womshayeli abe yingcindezi yoketshezi olusebenzayo kusekethe yokushayela.
I-GVC ingenye yezingxenye eziyinhloko ze-hydraulic clutch actuator.Amasilinda amakhosi kanye nesigqila, axhunywe ngepayipi lensimbi, enza isifunda esivaliwe se-hydraulic drive, ngosizo lapho i-clutch ivaliwe futhi ihlanganyele.I-GVC ifakwe ngqo ngemuva kwe-clutch pedal futhi ixhunywe kuyo ngenduku (i-pusher), isilinda sesigqila sifakwe ku-clutch house (insimbi) futhi ixhunywe ngentonga (pusher) kwimfoloko yokukhulula i-clutch.
I-master cylinder idlala indima ebalulekile ekusebenzeni kokudluliselwa, lapho iphuka, ukushayela imoto kuba nzima noma akunakwenzeka ngokuphelele.Kodwa ukuze uthenge isilinda esisha, kubalulekile ukuqonda ukuklama nezici zalo mshini.
Izinhlobo zamasilinda e-clutch master
Wonke ama-GCP anomklamo ofanayo kanye nesimiso sokusebenza, kodwa ahlukaniswe ngezinhlobo eziningana ngokuya ngendawo kanye nokwakheka kwethangi elinoketshezi olusebenzayo, inani lamaphistoni kanye nokwakheka komzimba wonke.
Ngokwendawo kanye nokwakheka kwethangi, amasilinda yilawa:
● Nechibi elihlanganisiwe loketshezi olusebenzayo kanye nethangi elikude;
● Ngethangi elikude;
● Ngethangi elisendaweni yesilinda.
| I-Clutch master cylinder ene-reservoir ehlanganisiwe | I-Clutch master cylinder ene-reservoir ekude | I-Clutch master cylinder ene-reservoir efakwe emzimbeni |
Uhlobo lokuqala lwe-GCS wumklamo ophelelwe yisikhathi ongavamile ukusetshenziswa namuhla.Umshini onjalo ufakwe ngokuqondile noma nge-engeli ethile, engxenyeni yayo engenhla kukhona ithangi elinoketshezi olusebenzayo, ukunikezwa kwalo okugcwaliswa ku-tank ekude.Amasilinda ohlobo lwesibili nolwesithathu asevele eseyimishini yesimanjemanje, kwelinye lawo ithangi likude futhi lixhunywe ku-cylinder nge-hose, kanti kwelinye ithangi lifakwe ngqo emzimbeni we-cylinder.
Ngokwenani lamapiston e-GCS, kukhona:
● Ngepiston elilodwa;
● Ngamapiston amabili.
| I-Single-piston clutch master cylinder | I-Clutch master cylinder enamapiston amabili |
Esimweni sokuqala, i-pusher ixhunywe ku-piston eyodwa, ngakho amandla avela ku-clutch pedal adluliselwa ngqo oketshezini olusebenzayo.Esimweni sesibili, i-pusher ixhunywe ku-piston ephakathi, esebenza ku-piston eyinhloko bese ingena kuketshezi olusebenzayo.
Okokugcina, ama-GCA angaba nezici ezihlukahlukene zokuklama, isibonelo - kwezinye izimoto, le divayisi yenziwa esimweni esisodwa ne-master brake cylinder, amasilinda angatholakala ngokuqondile, ngokuvundlile noma nge-engeli ethile, njll.
Idizayini kanye nesimiso sokusebenza kwamasilinda ayinhloko we-clutch
Umdwebo ojwayelekile wedrayivu yokukhishwa kwe-hydraulic clutch
Okulula kakhulu ukuhlelwa kwe-GCS ngethangi elisusiwe lafakwa emzimbeni.Isisekelo sedivayisi siyi-cylindrical cast case, lapho kwenziwa khona ama-eyelets okufaka ama-bolts nezinye izingxenye.Ngakolunye uhlangothi, umzimba uvalwa ngepulaki elinentambo noma ipulaki enokulingana ukuze kuxhunywe epayipini.Uma umzimba uvaliwe ngepulaki eyimpumputhe, khona-ke ukufakwa kutholakala endaweni eseceleni yesilinda.
Engxenyeni emaphakathi yesilinda, kukhona okufanelekile ukuxhuma ethangini ngepayipi noma isihlalo sokufaka ithangi ngqo emzimbeni.Ngaphansi kokufaneleka noma esihlalweni endlini yesilinda, kwenziwa izimbobo ezimbili: imbobo yesinxephezelo (i-inlet) ye-diameter encane kanye nomgodi wokuchichima we-diameter eyengeziwe.Izimbobo zihlelwe ngendlela yokuthi lapho i-clutch pedal ikhishwa, imbobo yesinxephezelo itholakala phambi kwe-piston (kusuka ohlangothini lwesifunda se-drive), futhi umgodi wokudlula utholakala ngemuva kwepiston.
I-piston ifakwe emgodini womzimba, ngakolunye uhlangothi kukhona i-pusher exhunywe ku-clutch pedal.Ukuphela komzimba ohlangothini lwe-pusher kumbozwe ngekepisi lenjoloba likathayela elivikelayo.Lapho i-clutch pedal icindezelekile, i-piston ihlehliswa endaweni ephakeme kakhulu nge-spring spring etholakala ngaphakathi kwesilinda.Ama-GCA anamaphiston amabili asebenzisa amapiston amabili abekwe ngokulandelana, phakathi kwamapiston kukhona i-O-ring (cuff).Ukusetshenziswa kwama-pistons amabili kuthuthukisa ukuqina kwesekethe ye-clutch drive futhi kukhulisa ukuthembeka kwalo lonke uhlelo.
Induku.Lesi yisisekelo senduku yokuxhuma ehlanganisa amakhanda futhi iqinisekise ukudluliswa kwamandla kusuka ekhanda le-piston kuya ku-crank.Ubude benduku bunquma ukuphakama kwamapiston nokushaywa kwawo, kanye nokuphakama okuphelele kwenjini.Ukufeza ukuqina okudingekayo, amaphrofayili ahlukahlukene anamathiselwe ezintini:
● I-i-beam ngokuhlelwa kwamashalofu aqondile noma ahambisana nezimbazo zamakhanda;
● I-Cruciform.
Ngokuvamile, induku inikezwa iphrofayili ye-I-beam ene-longitudinal yokuhlelwa kwamashalofu (ngakwesokudla nakwesobunxele, uma ubheka induku yokuxhuma eduze nezimbazo zamakhanda), amanye amaphrofayili asetshenziswa kancane.
Ishaneli ibholwa ngaphakathi kwenduku ukuze kuhlinzekwe amafutha kusukela ekhanda elingezansi kuya ekhanda elingaphezulu, kwezinye izinduku zokuxhuma amagophe aseceleni enziwa kusukela kumzila omaphakathi ukuze kufafazwe uwoyela ezindongeni zesilinda nezinye izingxenye.Ezindongeni ze-I-beam, esikhundleni sesiteshi esiboshiwe, ithubhu yokuhlinzeka ngamafutha ensimbi exhunywe kwinduku enabakaki bensimbi ingasetshenziswa.
Ngokuvamile, induku imakwa futhi imakwe ukuze kufakwe ingxenye efanele.
Ikhanda le-piston.Imbobo iqoshwe ekhanda, lapho kucindezelwa khona umkhono wethusi, odlala indima yokuthwala ithafa.Iphinikhodi ye-piston ifakwe emkhonweni ngegebe elincane.Ukuze ugcobe izindawo zokungqubuzana zephini kanye nomkhono, imbobo yenziwa ekugcineni ukuze kuqinisekiswe ukugeleza kwamafutha kusuka esiteshini ngaphakathi kwenduku yenduku yokuxhuma.
Ikhanda le-crank.Leli khanda liyalahleka, ingxenye yalo engezansi yenziwe ngendlela yekhava ekhishwayo ebekwe phezu kwenduku yokuxhuma.Isixhumi singaba:
● Iqonde - indiza yesixhumi isendaweni efanele endongeni;
● I-Oblique - indiza yesixhumi yenziwe nge-engeli ethile.
| Induku yokuxhuma ngesixhumi sekhava eqondile | Induku yokuxhuma ene-oblique cover connector |
Amasilinda anjalo asebenza kanje.Lapho i-clutch pedal ikhishwa, i-piston isesimweni esibi kakhulu ngaphansi kwethonya lentwasahlobo yokubuya futhi ukucindezela komkhathi kugcinwa kumjikelezo we-clutch drive (njengoba i-cavity yokusebenza yesilinda ixhunywe ku-reservoir ngokusebenzisa imbobo yesinxephezelo).Lapho i-clutch pedal icindezelwa, i-piston ihamba ngaphansi kwethonya lamandla onyawo futhi ijwayele ukucindezela uketshezi kumjikelezo wedrayivu.Lapho i-piston ihamba, imbobo yesinxephezelo iyavala futhi ingcindezi kumjikelezo wedrayivu iyanda.Ngesikhathi esifanayo, uketshezi lugeleza embotsheni yokudlula ngemuva kohlangothi olungemuva lwepiston.Ngenxa yokwanda kwengcindezi kumjikelezo, i-piston yesilinda esisebenzayo inyakaza futhi inyakaze imfoloko yokukhishwa kwe-clutch, ephusha i-rearing bear - i-clutch inqanyuliwe, ungashintsha igiya.
Ngesikhathi sokukhululwa kwe-pedal, i-piston ku-GVC ibuyela endaweni yayo yasekuqaleni, ingcindezi kumjikelezo wehla futhi i-clutch ihileleke.Lapho i-piston ibuyiswa, uketshezi olusebenzayo olunqwabelene ngemuva kwalo lukhinyabezwa ngaphandle kwe-bypass port, okuholela ekunciphiseni ukunyakaza kwepiston - lokhu kuqinisekisa ukubandakanyeka okushelelayo kwe-clutch kanye nokubuyiselwa kwalo lonke uhlelo endaweni yalo yokuqala. isimo.
Uma kukhona ukuvuza koketshezi olusebenzayo kusekethe (okungenakugwenywa ngenxa yokuqina okunganele kwamalunga, ukulimala kwezimpawu, njll.), khona-ke inani elidingekayo loketshezi livela ethangini ngokusebenzisa imbobo yesinxephezelo.Futhi, le mbobo iqinisekisa ukungaguquguquki kwevolumu yoketshezi olusebenzayo ohlelweni lapho izinga lokushisa lishintsha.
Ukuklanywa nokusebenza kwesilinda esine-reservoir ehlanganisiwe yoketshezi olusebenzayo kuhluke kancane kulokho okuchazwe ngenhla.Isisekelo sale GVC siwumzimba wabalingisi okhwezwe mpo noma nge-engeli.Engxenyeni engenhla yomzimba kukhona indawo yokugcina amanzi asebenzayo, ngaphansi kwethangi kukhona isilinda esinepiston elayishwe entwasahlobo, kanti ipusher exhunywe ku-clutch pedal idlula ethangini.Odongeni lwethangi kungase kube nepulaki yokugcwalisa uketshezi olusebenzayo noma into yokuxhuma ithangi elikude.
I-piston engxenyeni engenhla ine-recess, imbobo yobubanzi obuncane ibhotshwa eduze kwepiston.I-pusher ifakwe ngaphezu komgodi, esimweni esihoxisiwe kukhona igebe phakathi kwabo lapho uketshezi olusebenzayo lungena khona ku-cylinder.
I-GVC enjalo isebenza kalula.Lapho i-clutch pedal ikhishwa, ingcindezi yasemkhathini ibonakala kumjikelezo we-hydraulic, i-clutch ibanjwe.Ngesikhathi sokucindezela i-pedal, i-pusher ihlehla, ivale imbobo ku-piston, ivale uhlelo, futhi iphushele i-piston phansi - ukucindezela kumjikelezo kuyakhuphuka, futhi isilinda esisebenzayo sivule imfoloko yokukhulula i-clutch.Lapho i-pedal ikhishwa, izinqubo ezichazwe zenziwa ngokulandelana okuphambene.Ukuvuza koketshezi olusebenzayo kanye nokushintsha kwevolumu yayo ngenxa yokushisa kunxeshezelwa ngembobo yepiston.
Ukukhetha okulungile, ukulungiswa nokushintshwa kwama-GVC
Ngesikhathi sokusebenza kwemoto, i-GCC ithwala kanzima, okuholela ekugugeni kancane kancane kwezingxenye zayo ngazinye, ikakhulukazi ama-piston cuffs (amapiston) kanye nezimpawu zenjoloba.Ukugqoka kwalezi zingxenye kubonakala ngokuvuza koketshezi olusebenzayo kanye nokuwohloka kwe-clutch (i-pedal dips, isidingo sokucindezela i-pedal izikhathi eziningana, njll.).Inkinga ixazululwa ngokushintsha izingxenye ezigugile - kulokhu udinga ukuthenga ikhithi yokulungisa futhi wenze umsebenzi olula.Ukudilizwa, ukuhlakazeka, ukushintshwa kwezingxenye kanye nokufakwa kwe-cylinder kufanele kwenziwe ngokuhambisana nemiyalelo yokulungisa nokugcinwa kwemoto.
Kwezinye izimo, kukhona ukungasebenzi kahle kwe-clutch master cylinder - ukuqhekeka, ukuphuka kwezindlu, ukuphuka kokufakwa, njll. Ukuze ushintshe, udinga ukukhetha i-cylinder yohlobo olufanayo nenombolo yekhathalogi eyayifakwe emotweni ngaphambili. , ngaphandle kwalokho isilinda ngeke sikwazi ukufakwa nhlobo, noma i-clutch ngeke isebenze kahle.
Ngemuva kokufaka i-GVC entsha, kuyadingeka ukulungisa i-clutch ngokuhambisana nezincomo zemiyalelo.Imvamisa, ukulungiswa kwenziwa ngokushintsha ubude benduku (kusetshenziswa inati elifanele) le-pedal kanye nendawo ye-piston pusher, ukulungiswa kufanele kusethwe ngokushaywa kwamahhala kwe-clutch pedal enconywe umenzi wemoto (25) -45 mm ezimotweni ezahlukene).Esikhathini esizayo, kuyadingeka ukugcwalisa izinga le-liquid ethangini futhi uqaphe ukubukeka kokuvuza ohlelweni.Ngokulungiswa okufanele kanye nokugcinwa njalo, ama-GVC kanye nayo yonke i-clutch drive izohlinzeka ngokulawulwa kokudlulisela okuqiniseka kuzo zonke izimo.
