Idivayisi kanye nomgomo wokusebenza kwesilinda esikhulu sokubopha

Isici esiphakathi kohlelo lokubhaka amabhuleki wemoto yi-brake master cylinder (efushaniswe njenge-GTZ). Iguqula umzamo osuka kubhuleki lokunyathela ube umfutho wokubacindezela ohlelweni. Ake sicabangele imisebenzi ye-GTZ, isakhiwo sayo kanye nenqubo yokusebenza. Ake sinake izici zokusebenza kwe-element lapho kwenzeka ukwehluleka komunye wemigqa yayo.

I-Master cylinder: inhloso nomsebenzi wayo

Ngesikhathi unyathela amabhuleki, umshayeli usebenza ngqo kwi-brake pedal, edluliselwa kuma-piston we-master cylinder. Ama-piston, asebenza ku-brake fluid, enza ama-cylinders asebenzayo asebenze. Kusuka kubo, futhi, ama-piston enwetshiwe, acindezele ama-brake pads ngokumelene nezigubhu noma ama-disc. Ukusebenza kwesilinda esikhulu sebhuleki kusekelwe emphethweni we-brake fluid ukuthi ungacindezelwa ngaphansi kwesenzo samandla angaphandle, kepha ukudlulisa ingcindezi.

I-master cylinder inemisebenzi elandelayo:

• ukudluliswa kwamandla emishini kusuka esakhiweni sebhuleki usebenzisa ukubopha uketshezi kuya kumasilinda asebenzayo;
• ukuqinisekisa ukubopha amabhuleki ngempumelelo kwemoto.

Ukuze kwandiswe izinga lokuphepha futhi kuqinisekiswe ukuthembeka okuphezulu kohlelo, ukuhlinzekwa kokufakwa kwamasilinda amakhulu ayizigaba ezimbili. Isigaba ngasinye sisebenza ngesifunda saso sokubacindezela. Ezimotweni ezidonsa ngamasondo angemuva, isekethe lokuqala libhekelela amabhuleki amasondo angaphambili, okwesibili ngamasondo angemuva. Emotweni edonsa ngamasondo angaphambili, amabhuleki amasondo angakwesokudla ngaphambili nangakwesokunxele anikwa isekethe yokuqala. Owesibili ubhekele amabhuleki amasondo angaphambili kwesokunxele nangakwesokudla ngemuva. Lolu hlelo lubizwa ngokuthi idiagonal futhi lusetshenziswa kakhulu.

Idivayisi isilinda main ukubopha

I-master cylinder itholakala kwikhava le-brake servo. Umdwebo wesakhiwo se-main brake cylinder ulandelayo:

• umzimba;
• ithangi (ichibi) i-GTZ;
• i-piston (ama-2 ama-PC.);
• buyisela iziphethu;
• uphawu cuffs.

Idamu elikhulu le-master cylinder fluid litholakala ngqo ngaphezu kwesilinda futhi lixhunywe ezingxenyeni zalo ngokusebenzisa izimbobo zokudlula nezimbuyiselo. Idamu liyadingeka ukugcwalisa uketshezi olusehlelweni lwamabhuleki uma kwenzeka kuvuza noma kuhwamuka. Izinga le-liquid lingabhekwa ngokubonakalayo ngenxa yezindonga ezisobala zethangi, lapho kutholakala khona amamaki wokulawula.

Ngaphezu kwalokho, inzwa ekhethekile ethangini iqapha izinga loketshezi. Uma kwenzeka ukuthi uketshezi luwela ngaphansi kwesilinganiso esinqunyiwe, isibani sesixwayiso esisephaneli yethuluzi siyakhanya.

Izindlu zeGTZ ziqukethe ama-piston amabili aneziphethu zokubuyisa kanye nezindishi zokuvala injoloba. Ama-cuffs ayadingeka ukuvala ama-piston ezindlini, kanti intwasahlobo inikeza ukubuya futhi ibambe ama-piston endaweni yawo yoqobo. Ama-piston ahlinzeka ingcindezi efanele yokubamba uketshezi.

I-brake master cylinder ingafakwa ngokuzikhethela ngenzwa yokucindezela ehlukile. Lesi sakamuva siyadingeka ukuxwayisa umshayeli ngokungasebenzi kahle kwelinye lamasekethe ngenxa yokulahleka kobunzima. Inzwa yengcindezi ingatholakala kokubili ku-brake master cylinder nasendlini ehlukile.

Isimiso sokusebenza kwe-brake master cylinder

Okwamanje isicucu samabhuleki sicindezelwe, induku yokulekelela iqala ukucindezela i-piston eyinhloko yesifunda. Ngenkathi yokuhamba, ivala umgodi wokunweba, ngenxa yokuthi ingcindezi kulesi sifunda iqala ukwanda. Ngaphansi kwesenzo sengcindezi, isekethe lesibili liqala ukunyakaza kwalo, ingcindezi nayo ekhuphuka.

Ngomgodi wokudlula, uketshezi lwamabhuleki lungena esikhaleni esakhiwe ngesikhathi sokuhamba kwama-piston. Ama-piston ahamba inqobo nje uma intwasahlobo ebuyayo kanye nezitobhi ezindlini zivumela lokho. Amabhuleki asetshenziswa ngenxa yengcindezi enkulu edalwe kuma-piston.

Ngemuva kokumisa imoto, ama-piston abuyela endaweni yawo yokuqala. Kulokhu, ingcindezi esezifundeni kancane kancane iqala ukuhambisana naleyo esemkhathini. Ukukhishwa kumasekethe asebenzayo kuvinjelwe i-brake fluid, egcwalisa izikhala ezingemuva kwamapiston. Lapho i-piston ihamba, uketshezi lubuyela ethangini ngembobo yokudlula.

Ukusebenza kwesistimu uma kwehluleka elinye lamasekethe

Uma kwenzeka kuvuza uketshezi lwamabhuleki kwelinye lamasekethe, owesibili uzoqhubeka nokusebenza. I-piston yokuqala izohamba ngesilinda ize ixhumane ne-piston yesibili. Lesi sakamuva sizoqala ukunyakaza, ngenxa yokuthi amabhuleki wesifunda sesibili azocushwa.

Uma ukuvuza kwenzeka esifundeni sesibili, i-brake master cylinder izosebenza ngendlela ehlukile. I-valve yokuqala, ngenxa yokuhamba kwayo, ishayela i-piston yesibili. Lesi sakamuva sihamba ngokukhululeka kuze kube yilapho isitobhi sifinyelela ekugcineni komzimba wesilinda. Ngenxa yalokhu, ingcindezi esifundeni sokuqala iqala ukukhuphuka, futhi imoto ibhulekiwe.

Noma ngabe ukuhamba kwamabhuleki kukhushulwa ngenxa yokuvuza koketshezi, imoto izohlala ilawula. Noma kunjalo, ukubopha amabhuleki ngeke kuphumelele kangako.
