Isilinda esikhulu (i-Master Cylinder), esaziwa nangokuthi uwoyela oyinhloko wamabhuleki (umoya), umsebenzi waso oyinhloko ukusunduza uketshezi lwamabhuleki (noma igesi) ukuze ludluliselwe kusilinda ngasinye samabhuleki ukuze kusunduzwe i-piston.
Isilinda se-brake master siyi-cylinder ye-hydraulic ye-piston esebenza ngendlela eyodwa, futhi umsebenzi wayo ukuguqula okufakwayo kwamandla omshini yi-pedal mechanism kube amandla e-hydraulic. Kunezinhlobo ezimbili zama-cylinder e-brake master, i-single-chamber kanye ne-dual-chamber, ezisetshenziswa ngokulandelana ezinhlelweni zokubhuleka ze-hydraulic ze-single-circuit kanye ne-dual-circuit.
Ukuze kuthuthukiswe ukuphepha kokushayela kwezimoto, ngokwezidingo zemithethonqubo yethrafikhi, uhlelo lokubhuleka kwesevisi yezimoto manje selusebenzisa uhlelo lokubhuleka olunezisekelo ezimbili, olwakhiwe uchungechunge lwamasilinda amakhulu egumbi eli-1 (amasilinda amakhulu egumbi eli-1 asusiwe). uhlelo lokubhuleka olunezisekelo ezimbili.
Njengamanje, cishe zonke izinhlelo zokubhuleka ze-hydraulic ze-dual-circuit ziyizinhlelo zokubhuleka ze-servo noma izinhlelo zokubhuleka ezishintshashintshayo. Kodwa-ke, kwezinye izimoto ezincane noma ezilula, ukuze kwenziwe isakhiwo sibe lula, futhi ngaphansi kwesimo sokuthi amandla e-brake pedal awadluli ububanzi bamandla omzimba womshayeli, kukhona futhi amanye amamodeli asebenzisa isilinda esikhulu se-tandem dual-chamber brake master ukuze akhe uhlelo lwe-dual-circuit manual hydraulic brake.
Isakhiwo sesilinda esikhulu sebhuleki eliphindwe kabili esihlanganisiwe
Lolu hlobo lwesilinda se-brake master lusetshenziswa ohlelweni lwe-hydraulic brake olunezijikelezo ezimbili, olulingana namasilinda amabili e-brake master e-single chamber axhunywe ochungechungeni.
Indlu yesilinda esikhulu sebhuleki ifakwe i-piston yesilinda sangaphambili 7, i-piston yesilinda sangemuva 12, isipilingi sangaphambili sesilinda 21 kanye nesipilingi sangemuva sesilinda 18.
I-piston yesilinda engaphambili ivalwe ngendandatho yokuvala 19; i-piston yesilinda engemuva ivalwe ngendandatho yokuvala 16, futhi ibekwe ngendandatho yokugcina 13. Ama-reservoir amabili oketshezi axhunyaniswa ngokulandelana nekamelo elingaphambili B kanye nekamelo elingemuva A, futhi axhunyaniswa namasilinda esondo lebhuleki elingaphambili nelingemuva ngama-valve awo okukhipha uwoyela 3. I-piston yesilinda engaphambili icindezelwa amandla e-hydraulic e-piston yesilinda engemuva, kanti i-piston yesilinda engemuva iqhutshwa ngqo yinduku yokucindezela. 15 push.
Uma isilinda esikhulu sebhuleki singasebenzi, ikhanda le-piston kanye nendebe emakamelweni angaphambili nangemuva kutholakala phakathi kwemigodi ye-bypass 10 kanye nemigodi yokubuyisela 11. Amandla okunwebeka entwasahlobo yokubuya ye-piston yesilinda sangaphambili makhulu kunalawo entwasahlobo yokubuya ye-piston yesilinda sangemuva ukuqinisekisa ukuthi ama-piston amabili asesimweni esifanele uma engasebenzi.
Uma ubhuleka, umshayeli unyathela i-pedal yebhuleki, amandla e-pedal adluliselwa entongeni yokusunduza 15 ngendlela yokudlulisa, bese esunduza i-piston yesilinda yangemuva 12 ukuze iqhubekele phambili. Ngemva kokuba indebe yesikhumba imboze umgodi we-bypass, ingcindezi engaphakathi kwesikhala sangemuva iyanda. Ngaphansi kwesenzo sengcindezi ye-hydraulic ekamelweni langemuva kanye namandla entwasahlobo esilinda sangemuva, i-piston 7 yesilinda sangaphambili iya phambili, kanti ingcindezi engaphakathi kwegumbi langaphambili nayo iyakhula. Lapho i-pedal yebhuleki iqhubeka nokucindezelwa phansi, ingcindezi ye-hydraulic emagumbini angaphambili nangemuva iyaqhubeka nokukhula, okwenza amabhuleki angaphambili nangemuva abhuleke.
Uma ibhuleki likhishwa, umshayeli ukhulula iphedali yebhuleki, ngaphansi kokusebenza kwezipilingi zepiston zangaphambili nangemuva, i-piston kanye nenduku yokusunduza esilinda sebhuleki kubuyela endaweni yokuqala, bese uwoyela osepayipini ucindezela ukuvula ivalvu yokubuyisela uwoyela 22 bese ugeleza emuva. Isilinda sebhuleki siyabhuleka, ukuze umphumela wokubhuleka unyamalale.
Uma isekethe elawulwa yigumbi langaphambili yehluleka, i-piston yesilinda sangaphambili ayikhiqizi ingcindezi ye-hydraulic, kodwa ngaphansi kwamandla e-hydraulic e-piston yesilinda sangemuva, i-piston yesilinda sangaphambili isunduzelwa phambili, futhi ingcindezi ye-hydraulic ekhiqizwa yigumbi langemuva isengenza isondo langemuva likhiqize amandla okubhuleka. Uma isekethe elawulwa yigumbi langemuva yehluleka, ikamelo langemuva alikhizi ingcindezi ye-hydraulic, kodwa i-piston yesilinda sangemuva iya phambili ngaphansi kwesenzo senduku yokusunduza, futhi ithinta i-piston yesilinda sangaphambili ukuze isunduzele i-piston yesilinda sangaphambili phambili, futhi ikamelo langaphambili lisengakhiqiza amabhuleki okucindezela e-Hydraulic amasondo angaphambili. Kungabonakala ukuthi uma noma yiliphi isethi yamapayipi ohlelweni lwe-hydraulic brake lwe-dual-circuit yehluleka, i-brake master cylinder isasebenza, kodwa i-pedal stroke edingekayo iyandiswa.
