Umgaqo wokusebenza we-brake ngokuyinhloko usuka kwi-friction, ukusetyenziswa kwe-brake pads kunye ne-disc ye-brake (i-drum) kunye namathayi kunye ne-friction yomhlaba, amandla e-kinetic yesithuthi aya kuguqulwa kumandla okushisa emva kokutshatyalaliswa, imoto iya kuyeka. Inkqubo efanelekileyo nesebenzayo yokuqhobosha kufuneka ibonelele ngokuzinzileyo, okwaneleyo kunye nokulawuleka kwamandla okuqhobosheka, kwaye ibe nokuhanjiswa kwe-hydraulic elungileyo kunye nomthamo wokuchitha ubushushu ukuqinisekisa ukuba amandla aqhutywa ngumqhubi osuka kwi-pedal ye-brake anokudluliselwa ngokupheleleyo nangempumelelo kwimpompo ephambili kunye iimpompo ezisezantsi, kwaye unqande ukusilela kwe-hydraulic kunye nokubola kwebhuleki okubangelwa kubushushu obuphezulu. Kukho iziqhoboshi zediski kunye neziqhoboshi zegubu, kodwa ukongeza kwinzuzo yeendleko, iziqhoboshi zegubu azisebenzanga kangako kunedisk brakes.
ingxabano
"Ukukhuhlana" kubhekiselele kuxhathiso lwentshukumo phakathi komphezulu wonxibelelwano wezinto ezimbini ezikwintshukumo ehambelanayo. Ubungakanani bamandla okukhuhlana (F) ngokomlinganiselo wemveliso yomlinganiso wokukhuhlana (μ) kunye noxinzelelo oluthe nkqo olulungileyo (N) kumphezulu wamandla okukhuhlana, obonakaliswa ngefomula ebonakalayo: F=μN. Kwinkqubo yeziqhoboshi: (μ) ibhekiselele kumlinganiso wokukhuhlana phakathi kwephedi yebrake kunye nediski yebrake, kwaye u-N yiPedal Force esetyenziswa yipiston yebrake yebrake kwibrake pad. I-coefficient ye-friction enkulu eveliswa kukukhuhla okukhulu, kodwa i-coefficient ye-friction phakathi kwe-brake pad kunye ne-disc iya kutshintsha ngenxa yobushushu obuphezulu obuveliswa yi-friction, oko kukuthi, i-coefficient ye-friction (μ) iyatshintshwa kunye iqondo lobushushu, uhlobo ngalunye lwephedi yokuqhawula ngenxa yezixhobo ezahlukeneyo kunye negophe elahlukileyo lokukhuhlana, ngoko ke iipakethi ezahlukeneyo zebrake ziya kuba nobushushu obuhlukeneyo bokusebenza, kunye nomgangatho wobushushu osebenzayo. wonke umntu kufuneka azi xa ethenga iibrake pads.
Ukudluliselwa kwamandla okuqhobosha
Amandla asetyenziswa yi-brake caliper piston kwi-brake pad ibizwa ngokuba yiPedal Force. Emva kokuba amandla omqhubi onyathela kwi-pedal ye-brake anyuswe sisiphatho se-pedal mechanism, amandla anyuswa kukunyusa amandla e-vacuum kusetyenziswa umgaqo-siseko womahluko woxinzelelo lwe-vacuum ukutyhala impompo ye-brake master. Uxinzelelo lolwelo olukhutshwe yimpompo ye-brake master isebenzisa isiphumo sothumelo samandla esinganyamekiyo, esigqithiselwa kwimpompo nganye engaphantsi ngetyhubhu yebrake, kwaye "umgaqo wePASCAL" usetyenziselwa ukukhulisa uxinzelelo kunye nokutyhala ipiston ye-sub- impompo ukwenza amandla kwi-brake pad. Umthetho kaPascal ubhekisa kwinto yokuba uxinzelelo lolwelo luyafana kuyo yonke indawo kwisikhongozeli esivaliweyo.
Uxinzelelo lufunyenwe ngokuhlula amandla asetyenzisiweyo ngendawo egxininisiweyo. Xa uxinzelelo lulingana, sinokufikelela umphumo wokukhulisa amandla ngokuguqula umlinganiselo wendawo esetyenzisiweyo kunye noxinzelelo (P1 = F1 / A1 = F2 / A2 = P2). Kwiinkqubo ze-braking, umlinganiselo wempompo epheleleyo kwi-sub-pump yoxinzelelo ngumlinganiselo wendawo yepiston yempompo epheleleyo ukuya kwindawo yepiston ye-sub-pump.
