Ithini iphampu ye-brake master enebhodwe
Iphampu ye-automobile brake master enebhodwe yingxenye ebalulekile yohlelo lwamabhuleki emoto, umsebenzi wayo oyinhloko ukugcina uwoyela wamabhuleki, nokudlulisa amandla amabhuleki ngohlelo olusebenza ngamanzi, ukuze kuzuzwe ukwehla kwemoto noma ukuma. Iphampu eyinhloko yamabhuleki ngokuvamile itholakala endaweni yenjini futhi ixhunywe ebhodweni likawoyela wamabhuleki kanye ne-subpump yebhuleki.
Isimiso sokusebenza sephampu ye-brake master
Lapho umshayeli ecindezela i-brake pedal, i-piston ku-brake master pump iphushwa i-pedal, ecindezela uwoyela webhuleki. Amafutha amabhuleki acindezelwe adluliselwa empompini yebhuleki ngayinye ngepayipi likawoyela, futhi ipiston empompini iyaphushwa ukuze ithinte iphedi yebhuleki nesigubhu sebhuleki ngemva kokucindezela, okukhiqiza ukungqubuzana, ukuze kuzuzwe umphumela wokubhuleka. Lapho ibhuleki i-pedal ikhululwa, amafutha ebhuleki ageleza abuyele empompini eyinhloko, alungele ibhuleki elilandelayo.
Amafutha ebhuleki angasebenza
Ibhodwe likawoyela wamabhuleki lisetshenziselwa ukugcina uwoyela wamabhuleki nokuqinisekisa ukuthi isistimu yamabhuleki inemithombo eyanele ye-hydraulic. Ibhodwe likawoyela wamabhuleki liklanywe kucatshangelwa ibhalansi yengcindezi, evumela umoya ukuthi ungene futhi uphume ngezintuba ukuze ulondoloze ukucindezela okuzinzile ebhodweni likawoyela. Ngenxa yokuthi umoya uqukethe umhwamuko wamanzi, amafutha ebhuleki ebhodweni lamafutha ebhuleki azomunca kancane kancane amanzi, okuzothinta ukusebenza kwamabhuleki, ngakho-ke kuyadingeka ukuhlola nokushintsha uwoyela webhuleki njalo.
Umsebenzi oyinhloko wepompo ye-brake master ukugcina uwoyela wamabhuleki kanye nokudlulisa amandla okubhuleka ngowoyela wamabhuleki. .
I-brake master pump ingenye yezingxenye ezibalulekile ze-automotive brake system, futhi umsebenzi wayo omkhulu ukushayela ukushayisana phakathi kwe-brake pad kanye nesigubhu sebhuleki ukuze kuzuzwe ukwehla kwemoto ngisho nokuma. Lapho umshayeli ecindezela i-pedal yebhuleki, i-piston kupompo ye-brake master iqhutshwa yi-pedal, futhi umfutho wamafutha webhuleki udluliselwa kumaphampu amancane ngokusebenza kwe-push rod. Le nqubo isakaza izicathulo zamabhuleki ngaphandle, iqinisekisa ukuthi amabhuleki axhumene nengaphakathi lesigubhu sebhuleki, akhiqize umphumela wokubhuleka .
Imisebenzi ethile yepompo ye-brake master enebhodwe ihlanganisa:
Gcina uwoyela wamabhuleki : Ibhodwe likawoyela wamabhuleki lisetshenziselwa ukugcina uwoyela wamabhuleki ukuze kuqinisekiswe ukuthi isistimu yamabhuleki inemithombo ye-hydraulic eyanele ukuze isebenze.
ibhalansi yengcindezi : Ibhodwe likawoyela wamabhuleki liklanyelwe ukuvumela umoya ukuthi ungene futhi uphume ukuze ulondoloze ibhalansi yengcindezi ngaphakathi kwesistimu yamabhuleki. Lapho ibhuleki licindezelwa, umoya osebhodweni likawoyela webhuleki uyamuncwa, futhi lapho ibhuleki likhululwa, umoya uyaphuma, ukuze kugcinwe uhlelo lusebenza ngokujwayelekile.
vimbela umoya ukuthi ungangeni : isivalo sebhodwe likawoyela webhuleki siklanywe ngembobo yokukhipha umoya kanye ne-gasket yokuvala ukuze kuqinisekiswe ukuthi umoya wangaphandle ungangena lapho ibhuleki licindezelwa, futhi umoya ungaphuma lapho ibhuleki likhululwa, ukuze kuvinjwe umoya ukuthi ungangeni kuwoyela webhuleki futhi kuthinte umphumela wokubhuleka.
Umgomo wokusebenza wephampu yebhuleki yemoto enebhodwe ikakhulukazi uhlanganisa lezi zinyathelo ezilandelayo:
I-brake pedal operation : Uma umshayeli ecindezela ibhuleki elinyathelayo, i-piston ekupompo eyinhloko yebhuleki iyaphonseka, futhi lokhu kuhlohla kudluliselwa kuwoyela webhuleki nge-push rod.
Ukudluliswa kwengcindezi : uwoyela wamabhuleki ukhiqiza ingcindezi kumjikelezo kawoyela futhi udluliselwa ku-piston yepompo yebhuleki yesondo ngalinye ngepayipi likawoyela.
isenzo sokubhuleka : i-piston yepompo yegatsha ingaphansi kwengcindezi yokuphushela amabhuleki amabhuleki ngaphandle, ukuze amabhuleki amabhuleki kanye nokushayisana kwesigubhu sebhuleki, kukhiqize ukungqubuzana okwanele ukunciphisa isivinini sesondo, ukuze kufinyelele ukubhuleka.
ukukhululwa kwe-pressure : ngemva kokukhulula i-pedal yebhuleki, ukuzungezisa kwesondo kuzokwenza ipiston yephampu yegatsha imiswe kabusha, uwoyela we-hydraulic ubuyela ebhodweni likawoyela lepompo lamabhuleki eliyinhloko ngepayipi, futhi ibhuleki lingakhululwa.
Ngaphezu kwalokho, ukwakheka kwepompo ye-brake master ngebhodwe kuhlanganisa nezingxenye ezibalulekile nemisebenzi:
I-piston ne-push rod : Ipiston iphushwa ibhuleki bese iphusha uketshezi lwebhuleki, futhi i-push rod isebenza njengokudluliswa kwamandla.
uwoyela can : Gcina uwoyela wamabhuleki ukuze uqinisekise ukuthi kunomfutho kawoyela owanele ngesikhathi sokubhuleka.
Mayelana nokugcinwa nokugcinwa, kunconywa ukuthi uhlole izinga kanye nekhwalithi yamafutha e-brake njalo ukuze uqinisekise ukuthi amafutha ahlanzekile futhi angenawo umswakama, ngoba umswakama uzonciphisa indawo yokubilisa yamafutha e-brake futhi uthinte umphumela wokubopha. Ngasikhathi sinye, ukushintshwa okujwayelekile kukawoyela wamabhuleki kanye nokuhlanzwa kwesistimu yamabhuleki kungandisa impilo yesevisi yephampu yebhuleki eyinhloko futhi kuqinisekise ukuphepha kokushayela.
