I-Master brake cylinder - idivayisi kanye nesimiso sokusebenza

Umsebenzi wokuqala we-hydraulic drive yamabhuleki emoto ukuguqula amandla okucindezela i-pedal ibe umfutho we-fluid ngokulingana nayo emigqeni. Lokhu kwenziwa yi-main brake cylinder (GTZ), etholakala endaweni yesivikelo senjini futhi ixhunywe ngentonga ku-pedal.

Yini okufanele i-GTC yenze?

I-Brake fluid ayicindezeleki, ngakho-ke ukudlulisa ingcindezi ngayo kuma-piston amasilinda aphezulu, kwanele ukusebenzisa amandla ku-piston yanoma iyiphi yazo. Leyo eklanyelwe lokhu ngokukhethekile futhi exhunywe ku-pedal yebhuleki ibizwa ngokuthi eyinhloko.

I-GTZ yokuqala yahlelwa ukuba ibe sezingeni eliphansi kalula. Induku yayinanyathiselwe ku-pedal, umkhawulo wayo wesibili ucindezelwe phezu kwepiston nge-elastic sealing cuff. Isikhala esingemuva kwepiston sigcwele uketshezi oluphuma kusilinda ngokuhlanganiswa kwamapayipi. Kusukela phezulu, kwanikezwa uketshezi oluqhubekayo oluqukethwe ethangini lokugcina. Yile ndlela amasilinda e-clutch master ahlelwa ngayo manje.

Kodwa isistimu yamabhuleki ibaluleke kakhulu kunokulawula i-clutch, ngakho-ke imisebenzi yayo kufanele iphindwe. Abazange baxhumanise amasilinda amabili komunye nomunye; isixazululo esinengqondo kwakuwukudala i-GTZ eyodwa yohlobo lwe-tandem, lapho ama-piston amabili atholakala ochungechungeni kusilinda esisodwa. Ngamunye wabo usebenza kumjikelezo wakhe, ukuvuza okuvela komunye akunawo umphumela ekusebenzeni komunye. Ama-contours asakazwa phezu kwemishini yesondo ngezindlela ezahlukene, ngokuvamile kusetshenziswa isimiso se-diagonal, ikhodi, uma kwenzeka noma yikuphi ukwehluleka okukodwa, amabhuleki engemuva elilodwa nesondo elilodwa langaphambili ahlala esebenza, kodwa hhayi ohlangothini olulodwa, kodwa eduze nomgwaqo. i-diagonal yomzimba, ngaphambili kwesokunxele nangemuva kwesokudla noma okuphambene nalokho. Nakuba kunezimoto lapho amapayipi awo womabili amasekhethi elingana namasondo angaphambili, asebenza kuwo amasilinda ahlukene.

Izingxenye ze-GTZ

Isilinda sinamathiselwe esivikelweni senjini, kodwa hhayi ngqo, kodwa nge-vacuum booster eyenza kube lula ukucindezela i-pedal. Kunoma yikuphi, induku ye-GTZ ixhunywe ku-pedal, ukwehluleka kwe-vacuum ngeke kuholele ekungasebenzini okuphelele kwamabhuleki.

I-GTC ihlanganisa:

• umzimba we-cylinder, lapho ama-piston ahamba khona;
• etholakala phezulu ethangini eline-brake fluid, enezinsimbi ezihlukene zesekethe ngayinye;
• amapiston amabili alandelanayo anemithombo yokubuya;
• ama-lip-type seal ku-piston ngayinye, kanye nasendaweni yokungena yezinduku;
• ipulaki enentambo evala isilinda kusukela ekugcineni okuphambene nenduku;
• ukufakwa kwe-pressure outlet ngayinye yamasekethe;
• i-flange yokukhweza emzimbeni we-vacuum booster.

I-reservoir yenziwe ngepulasitiki ebonakalayo, njengoba kubalulekile ukulawula njalo izinga le-brake fluid. Ukucosha umoya ngamapiston akwamukelekile, amabhuleki azohluleka ngokuphelele. Kwezinye izimoto, amathangi abekwe endaweni lapho umshayeli ebonakala khona njalo. Ngokulawulwa kude, amathangi afakwe inzwa yeleveli enenkomba yokuwa kwayo kuphaneli yensimbi.

I-oda lomsebenzi we-GTZ

Esimweni sokuqala, ama-pistons asendaweni yangemuva, imigodi ngemuva kwayo ixhumana noketshezi ethangini. Iziphethu ziwagcina ekunyakazeni okuzenzakalelayo.

Njengomphumela womzamo ovela endongeni, i-piston yokuqala iqala ukunyakaza futhi ivimbele ukuxhumana ne-tank ngomphetho wayo. Umfutho we-cylinder uyanda, futhi i-piston yesibili iqala ukunyakaza, idonsa uketshezi emgqeni wayo. Izikhala zikhethwa kulo lonke uhlelo, amasilinda asebenzayo aqala ukufaka ingcindezi kumapads. Njengoba cishe akukho ukunyakaza kwezingxenye, futhi uketshezi aluthinteki, ukuhamba okuqhubekayo kuyama, umshayeli ulawula ukucindezela kuphela ngokushintsha umzamo wonyawo. Ukuqina kokubhuleka kuncike kulokhu. Isikhala esingemuva kwamapiston sigcwele uketshezi ngokusebenzisa izimbobo zokunxephezela.

Lapho amandla esuswa, ama-piston abuyela ngaphansi kwethonya lemithombo, uketshezi luphinde lugeleze emigodini yokuvula ngokulandelana okuphambene.

Umgomo wokubhuka

Uma enye yezifunda ilahlekelwe ukuqina kwayo, khona-ke uketshezi ngemuva kwepiston elihambisanayo luzokhishwa ngokuphelele. Kodwa ukucindezela kabusha okusheshayo kuzonikeza uketshezi oluthe xaxa kumjikelezo omuhle, okwandisa ukuhamba kwe-pedal, kodwa ukucindezela kumjikelezo omuhle kuzobuyiselwa futhi imoto isazokwazi ukunciphisa. Akudingekile kuphela ukuphinda ukucindezela, ukulahla amanani amasha engeziwe kusuka ethangini lokucindezela ngokusebenzisa isekethe evuzayo. Ngemva kokumisa, kusala kuphela ukuthola ukungasebenzi kahle futhi ukuqede ngokupompa uhlelo emoyeni ovalelekile.

Ukungasebenzi kahle okungenzeka

Zonke izinkinga ze-GTZ zihlotshaniswa nokuhluleka kwezimpawu. Ukuvuza ngama-piston cuffs kuholela ku-fluid bypass, i-pedal izohluleka. Ukulungisa ngokufaka ikhithi akusebenzi, manje sekuyisiko ukufaka esikhundleni somhlangano we-GTZ. Ngalesi sikhathi, ukugqoka nokugqwala kwezindonga ze-cylinder sekuqalile, ukubuyiselwa kwabo akufanelekile ngokwezomnotho.

Ukuvuza kungabonwa futhi endaweni lapho ithangi linamathiselwe khona, lapha ukufaka esikhundleni sezimpawu kungasiza. I-tank ngokwayo inamandla ngokwanele, ukwephulwa kokuqina kwayo akuvamile.

Ukukhishwa kokuqala komoya kusilinda esisha kwenziwa ngokuwugcwalisa ngoketshezi ngamandla adonsela phansi ngokufakwa kwawo womabili amasekethe kukhululiwe. Ukupompa okuqhubekayo kwenziwa ngokusebenzisa ukufakwa kwamasilinda asebenzayo.
