Umgaqo osebenzayo webrake uvela kakhulu ekungqubaneni, ukusetyenziswa kwee-brake pads kunye ne-brake disc (drum) kunye namatayara kunye nokungqubana komhlaba, amandla e-kinetic esithuthi aya kuguqulwa abe ngamandla obushushu emva kokungqubana, imoto iya kuma. Inkqubo yokubhuleka elungileyo nesebenzayo kufuneka ibonelele ngamandla okubhuleka azinzileyo, aneleyo kwaye alawulekayo, kwaye ibe namandla okudlulisa amanzi amdaka kunye nokusasazwa kobushushu ukuqinisekisa ukuba amandla asetyenziswa ngumqhubi kwi-brake pedal anokudluliselwa ngokupheleleyo nangokufanelekileyo kwimpompo ephambili kunye nee-sub-pumps, kwaye kuthintelwe ukungaphumeleli kwe-hydraulic kunye nokubola kwee-brake okubangelwa kubushushu obuphezulu. Kukho ii-disc brakes kunye nee-drum brakes, kodwa ukongeza kwinzuzo yeendleko, ii-drum brakes azisebenzi kakuhle kakhulu kunee-disc brakes.
ukungqubana
"I-Friction" ibhekisa kukumelana kwentshukumo phakathi kwemiphezulu yoqhagamshelwano lwezinto ezimbini xa zihambelana nentshukumo. Ubungakanani bamandla okuxinana (F) buhambelana nemveliso ye-friction coefficient (μ) kunye noxinzelelo oluthe tye (N) kumphezulu wamandla okuxinana, oluchazwa yifomyula ebonakalayo: F=μN. Kwinkqubo yebrake: (μ) ibhekisa kwi-friction coefficient phakathi kwe-brake pad kunye ne-brake disc, kwaye i-N yiPedal Force esetyenziswa yi-brake caliper piston kwi-brake pad. Okukhona i-friction coefficient inkulu, kokukhona i-friction coefficient inkulu, kodwa i-friction coefficient phakathi kwe-brake pad kunye ne-disc iya kutshintsha ngenxa yobushushu obuphezulu obuveliswa yi-friction, oko kukuthi, i-friction coefficient (μ) itshintshwa ngobushushu, uhlobo ngalunye lwe-brake pad ngenxa yezinto ezahlukeneyo kunye ne-friction coefficient curve eyahlukileyo, ngoko ke ii-brake pads ezahlukeneyo ziya kuba nobushushu obufanelekileyo bokusebenza, kunye noluhlu lobushushu bokusebenza olufanelekileyo, oku kufuneka wonke umntu azi xa ethenga ii-brake pads.
Ukudluliselwa kwamandla okubhuleka
Amandla asetyenziswa yi-brake caliper piston kwi-brake pad abizwa ngokuba yiPedal Force. Emva kokuba amandla omqhubi onyathela i-brake pedal anyuswe yi-lever ye-pedal mechanism, amandla anyuswa yi-vacuum power boost esebenzisa umgaqo womahluko woxinzelelo lwe-vacuum ukutyhala i-brake master pump. Uxinzelelo lolwelo olukhutshwa yi-brake master pump lusebenzisa i-liquid incompressible power transmission effect, edluliselwa kwi-sub-pump nganye nge-brake tube, kwaye "umgaqo we-PASCAL" usetyenziselwa ukwandisa uxinzelelo kunye nokutyhala i-piston ye-sub-pump ukuze isebenzise amandla kwi-brake pad. Umthetho kaPascal ubhekisa kwinto yokuba uxinzelelo lolwelo lufana kuyo yonke indawo kwisikhongozeli esivaliweyo.
Uxinzelelo lufunyanwa ngokwahlula amandla asetyenziswayo ngendawo exinezelekileyo. Xa uxinzelelo lulingana, singafikelela kwisiphumo sokwandiswa kwamandla ngokutshintsha umlinganiselo wendawo esetyenzisiweyo kunye nendawo exinezelekileyo (P1=F1/A1=F2/A2=P2). Kwiinkqubo zokuqhobosha, umlinganiselo wepompo iyonke kuxinzelelo lwepompo encinci ngumlinganiselo wendawo yepiston yepompo iyonke kwindawo yepiston yepompo encinci.
