Idivayisi kanye nenqubo yokusebenza kwe-vacuum brake booster

I-vacuum booster ingenye yezinto ezibalulekile zohlelo lwamabhuleki ezimoto. Inhloso yalo enkulu ukukhulisa amandla adluliswa esuka enyaweni kuya ku-master brake cylinder. Ngenxa yalokhu, ukushayela kuba lula futhi kukhululeke ngokwengeziwe, futhi ukubopha amabhuleki kuyasebenza. Kulesi sihloko, sizohlaziya ukuthi i-amplifier isebenza kanjani, sithole ukuthi yiziphi izinto eziqukethe, futhi sithole nokuthi kungenzeka yini ngaphandle kwayo.

Umshini booster imisebenzi

Imisebenzi esemqoka yokuhlanza umshini (ukuqokwa okuvamile kwedivayisi) yile:

• ukwanda komzamo umshayeli acindezela ngawo iphedali yamabhuleki;
• ukuqinisekisa ukusebenza ngempumelelo kakhudlwana kohlelo lwamabhuleki ngesikhathi sokubopha amabhuleki okuphuthumayo.

I-vacuum amplifier idala amandla angeziwe ngenxa ye-vacuum evelayo. Futhi yilokhu kuqiniswa uma kwenzeka ibhuleki eliphuthumayo lemoto ihamba ngejubane elikhulu evumela ukuthi lonke uhlelo lwamabhuleki lusebenze kahle kakhulu.

Umshini brake booster device

Ngokwakheka, i-vacuum amplifier yicala elivalwe eliyindilinga. Ifakwe phambi kwesisekelo sebhuleki egumbini lenjini. Isigaxa esikhulu sebhuleki sitholakala emzimbeni waso. Kukhona olunye uhlobo lwedivayisi - i-hydraulic vacuum brake booster, efakwe engxenyeni ye-hydraulic yedrayivu.

I-vacuum brake booster iqukethe izinto ezilandelayo:

1. umzimba;
2. i-diaphragm (yamakhamera amabili);
3. ukuqapha valve;
4. ibhuleki pusher pusher;
5. induku ye-piston ye-hydraulic cylinder yamabhuleki;
6. buyela intwasahlobo.

Umzimba wedivayisi uhlukaniswe yidiaphragm yaba ngamakamelo amabili: i-vacuum ne-atmospheric. Owokuqala utholakala ohlangothini lwe-brake master cylinder, owesibili ohlangothini lwe-pedal brake. Nge-valve yokuhlola yesikhulisi, ikamelo lokuhlanza lixhunywe emthonjeni we-vacuum (vacuum), osetshenziswa njengokuphindaphindeka kokudla ezimotweni ezinenjini kaphethiloli ngaphambi kokunikeza uphethiloli kumasilinda.

Enjini kadizili, i-vacuum pump isebenza njengomthombo we-vacuum. Lapha, i-vacuum ekuphindaphindweni kokungeniswa ayinakwa, ngakho-ke ipompo kufanele. I-valve yokuhlola ye-vacuum brake booster iyayixhuma emthonjeni we-vacuum lapho injini imisiwe, kanye nalapho kwenzeka khona ukuthi i-vacuum pump ihluleke.

I-diaphragm ixhunywe ku-piston rod ye-master brake cylinder kusukela eceleni kwekamelo lokuhlanza. Ukuhamba kwayo kuqinisekisa ukuhamba kwepiston nomjovo woketshezi lwamabhuleki kuya kumasilinda esondo.

Igumbi elisemkhathini elisendaweni yokuqala lixhunywe ekamelweni elinomshini, futhi lapho iphediyali yamabhuleki icindezelwe, emoyeni. Ukuxhumana nomkhathi kunikezwa i-valve yomlandeli, ukunyakaza kwayo okwenzeka ngosizo lwe-pusher.

Ukuze kwandiswe ukusebenza kahle kwama-braking esimweni esiphuthumayo, uhlelo lokubopha amabhuleki oluphuthumayo ngendlela ye-electromagnetic rod drive olwengeziwe lungafakwa ekwakhiweni kwe-vacuum cleaner.

Umgomo wokusebenza kwe-vacuum brake booster

I-vacuum brake booster isebenza ngenxa yezingcindezi ezahlukahlukene zamagumbi. Kulokhu, esimweni sokuqala, ingcindezi kuwo womabili amakamelo izofana futhi ilingane nengcindezi eyenziwe ngumthombo we-vacuum.

Lapho i-pedal brake icindezelekile, i-pusher idlulisela amandla ku-valve yomlandeli, evala isiteshi esihlanganisa womabili amakamelo. Ukuqhubeka kokuhamba kwe-valve kusiza ukuxhumeka kwekamelo elisemkhathini ngomzila wokuxhuma emkhathini. Ngenxa yalokho, i-vacuum egumbini iyancipha. Umehluko wengcindezi emakamelweni uhambisa induku ye-piston ye-brake master cylinder. Lapho amabhuleki ephela, amakamelo axhuma kabusha futhi ingcindezi ekuwo ilingana. I-diaphragm, ngaphansi kwesenzo sentwasahlobo ebuyayo, ithatha isikhundla sayo sangempela. I-vacuum cleaner isebenza ngokulingana namandla okucindezela i-pedal brake, i.e. lapho umshayeli ecindezela kakhulu iphedali yamabhuleki, ilapho idivayisi izosebenza kahle khona.

Umshini Ukulekelela Izinzwa

Ukusebenza kahle kwe-vacuum booster ngokusebenza kahle kakhulu kuqinisekiswa uhlelo lwe-pneumatic braking system. Lesi sakamuva sihlanganisa inzwa elinganisa ijubane lokuhamba kwenduku yokukhulisa umsindo. Itholakala ngqo ku-amplifier.

Futhi ku-vacuum cleaner kukhona inzwa enquma izinga le-vacuum. Idizayinelwe ukukhombisa ukungabi nalutho ku-amplifier.

isiphetho

I-vacuum brake booster iyisici esibalulekile sohlelo lwe-braking. Ungenza, ngaphandle kwayo, kepha awudingi. Okokuqala, kufanele usebenzise umzamo owengeziwe lapho ubopha amabhuleki, kungadingeka ukuthi ucindezele nesinyathelo sokubhoda ngezinyawo zombili. Futhi okwesibili, ukushayela ngaphandle kwe-amplifier akuphephile. Esimweni lapho kubanjwa amabhuleki aphuthumayo, ibanga lamabhuleki lingavele linganeli.

Imibuzo nezimpendulo:

Iyini inhloso ye-vacuum brake booster valve? Le divayisi iqinisekisa ukukhishwa komoya ku-booster yebhuleki. Ivimbela umoya ukuthi ungangeni kulayini wamabhuleki, okungabangela ukuhluleka kwamabhuleki.

Isebenza kanjani i-valve ye-brake booster? Umgomo wokusebenza kwe-valve yokuhlola ye-vacuum brake booster ilula kakhulu. Ikhulula umoya ohlangothini olulodwa futhi ayivumeli umoya ukuthi ubuyele emuva.

Kwenzekani uma i-vacuum brake booster ingasebenzi? Ngomzamo ofanayo wokunyathela, imoto yaba yimbi kakhulu ukwehlisa ijubane. Uma ucindezela i-pedal, kuzwakala inyosi, ijubane lenjini liyakhuphuka. i-pedal ingase ibe nzima.

Ungahlola kanjani i-vacuum brake booster valve? Ukuze uhlole i-valve yokuhlola, kwanele ukuyikhipha ku-vacuum brake booster bese ushaya ipayipi efakwe kuyo ku-booster. I-valve enhle izogeleza ohlangothini olulodwa kuphela.
