Mfundo yogwirira ntchito ya brake imachokera ku kukangana, kugwiritsa ntchito ma brake pads ndi brake disc (ng'oma) ndi matayala ndi kugwedezeka kwapansi, mphamvu ya kinetic ya galimotoyo idzasinthidwa kukhala mphamvu ya kutentha pambuyo pa kukangana, galimoto idzayima.Dongosolo labwino komanso logwira ntchito bwino la braking liyenera kupereka mphamvu yokhazikika, yokwanira komanso yowongoka, komanso kukhala ndi ma hydraulic transmission and heat dissipation capacity kuonetsetsa kuti mphamvu ya dalaivala kuchokera pa brake pedal imatha kuperekedwa mokwanira komanso moyenera ku mpope wamkulu ndi mapampu ang'onoang'ono, ndikupewa kulephera kwa ma hydraulic ndi kuwola kwa mabuleki chifukwa cha kutentha kwakukulu.Pali mabuleki a ng'oma ndi mabuleki a ng'oma, koma kuwonjezera pa mtengo wake, mabuleki a ng'oma sagwira ntchito bwino kuposa mabuleki a disk.
kukangana
"Friction" imatanthawuza kukana kwa kuyenda pakati pa malo okhudzana ndi zinthu ziwiri zomwe zikuyenda.Kukula kwa mphamvu ya kukangana (F) kumayenderana ndi zomwe zimakokerana (μ) ndi kukakamiza koyimirira koyimirira (N) pamtunda wa mphamvu yogundana, yowonetsedwa ndi mawonekedwe akuthupi: F=μN.Pa ma brake system: (μ) amatanthauza kugundana pakati pa brake pad ndi brake disc, ndipo N ndi Pedal Force yoyendetsedwa ndi pisitoni ya brake caliper pa brake pad.Kuchulukirachulukira komwe kumapangidwa ndi kukangana kwakukulu, koma kugunda kwapakati pakati pa brake pad ndi disc kudzasintha chifukwa cha kutentha kwakukulu komwe kumapangidwa ndi kukangana, ndiko kunena kuti, kugunda kwapakati (μ) kumasinthidwa ndi kutentha, mtundu uliwonse wa pad ananyema chifukwa cha zipangizo zosiyanasiyana ndi kukangana koyenera pamapindikira, kotero ziyangoyango ananyema osiyana adzakhala osiyana mulingo woyenera kwambiri kutentha ntchito, ndi yogwira ntchito kutentha osiyanasiyana, ichi ndi aliyense ayenera kudziwa pogula ma brake pads.
Kusamutsa mphamvu ya braking
Mphamvu yoyendetsedwa ndi pisitoni ya brake caliper pa brake pad imatchedwa Pedal Force.Mphamvu ya dalaivala ikaponda pa brake pedal imakulitsidwa ndi chowongolera cha makina opondaponda, mphamvuyo imakulitsidwa ndi mphamvu ya vacuum yomwe imagwiritsa ntchito mfundo ya kusiyana kwa vacuum pressure kukankhira pampu ya brake master.Kuthamanga kwamadzimadzi komwe kumaperekedwa ndi mpope wa brake master kumagwiritsa ntchito mphamvu yamadzimadzi yosasunthika, yomwe imaperekedwa ku mpope uliwonse wapampopi kudzera pamachubu oboola, ndipo "PASCAL mfundo" imagwiritsidwa ntchito kukulitsa kuthamanga ndikukankhira pisitoni ya sub- mpope kuti agwiritse ntchito mphamvu pa brake pad.Lamulo la Pascal limatanthawuza kuti mphamvu yamadzimadzi imakhala yofanana paliponse mu chidebe chotsekedwa.
Kupanikizika kumapezeka mwa kugawa mphamvu yogwiritsidwa ntchito ndi malo opanikizika.Pamene kupanikizika kuli kofanana, tikhoza kukwaniritsa zotsatira za kukulitsa mphamvu mwa kusintha gawo la malo ogwiritsidwa ntchito ndi opanikizika (P1 = F1 / A1 = F2 / A2 = P2).Kwa ma braking systems, chiŵerengero cha pampu yonse ndi mphamvu ya pampu yaing'ono ndi chiŵerengero cha malo a pistoni a pampu yonse ndi pisitoni ya pampu yaing'ono.
