inkcazelo
Iipakethi zeBrake, ezikwabizwa ngokuba yi-automobile brake pads, zibhekisa kwisixhobo sokukhuhlana esimiswe kwigubu lebrake okanye idisk yebrake ejikeleza ngamavili.Iingcingo ezixubeneyo kunye neentsimbi ezixutywayo ziphantsi koxinzelelo lwangaphandle kwaye zivelise ukukhuhlana ukufezekisa injongo yokunciphisa isithuthi.
Iipakethi ze-automobile brake ngokubanzi zenziwe ngepleyiti yentsimbi, umaleko wokuncamathelisa kunye nebhloko yokukhuhlana.Ipleyiti yentsimbi kufuneka ipeyintwe ukuthintela umhlwa.I-SMT-4 ye-furnace tracker yokushisa isetyenziselwa ukufumanisa ukuhanjiswa kweqondo lokushisa kwenkqubo yokugubungela ukuqinisekisa umgangatho.
Umgaqo wokusebenza we-brake ikakhulu kwi-friction.Ukruthakruthwano phakathi kweephedi zebrake kunye neediski zebrake (amagubu) kunye namatayara kunye nomhlaba usetyenziselwa ukuguqula amandla e-kinetic esithuthi sibe ngamandla obushushu obukhuhlaneyo ukumisa imoto.Inkqubo ye-brake efanelekileyo nesebenzayo kufuneka ibonelele ngokuzinzileyo, okwaneleyo kunye nokulawulwa kwamandla okunyathela, kwaye ibe nokuhanjiswa okulungileyo kwe-hydraulic kunye nezakhono zokutshatyalaliswa kobushushu ukuqinisekisa ukuba amandla aqhutywe ngumqhubi kwi-pedal ye-brake inokudluliselwa ngokupheleleyo kwaye ngokufanelekileyo kwi-master cylinder Kwaye nganye i-sub-cylinder, kunye nokuphepha ukusilela kwe-hydraulic kunye nokuthotywa kwebhuleki okubangelwa kubushushu obuphezulu.Inkqubo yeziqhoboshi emotweni yahlulwe yangamacandelo amabini: idiskhi kunye negubu, kodwa ngaphandle kwenzuzo yeendleko, iziqhoboshi zegubu azisebenzanga kangako kunedisk brakes.
"Ukukhuhlana" kubhekiselele kuxhathiso lwentshukumo phakathi kweendawo ezidityaniswayo zezinto ezimbini ezishukumayo.Amandla okhuhlane (F) alingana nemveliso yomlinganiso wokukhuhlana (μ) kunye noxinzelelo oluthe nkqo oluqhelekileyo (N) kumphezulu wokungqubana, obonakaliswa njengefomula yomzimba: F=μN.Kwinkqubo yeziqhoboshi: (μ) ibhekiselele kumlinganiso wokukhuhlana phakathi kwephedi yebrake kunye nediski yebrake, kwaye i-N ngamandla asetyenziswa yipiston yebrake yebrake kwibhreyikhi pad (iPedal Force).I-coefficient ye-friction enkulu, i-coefficient ye-friction enkulu eyenziwe, kodwa i-coefficient ye-friction phakathi kwe-brake pad kunye ne-disc iya kutshintsha ngenxa yobushushu obuphezulu obuveliswa emva kokuxutywa, oko kukuthi, i-coefficient ye-friction (μ) iyatshintsha ngeqondo lokushisa Nangona kunjalo, uhlobo ngalunye lwephedi yokuqhobosha lune-coefficient ehlukeneyo yokutshintsha ijika ngenxa yokwahlukana kwezinto.Ke ngoko, iipakethi zeebhuleki ezahlukeneyo ziya kuba namaqondo obushushu ahlukeneyo okusebenza kunye nomgangatho wobushushu osebenzayo.Oku kuxa uthenga iibrake pads.Into ekufuneka uyazi.
Ukuhanjiswa kwamandla okuqhobosha
Amandla asetyenziswa yi-brake caliper piston kwi-brake pads kuthiwa: iPedal Force.Emva kokuba amandla omqhubi kwi-pedali ye-brake yandisiwe sisileva se-pedal mechanism, amandla ayandiswa ngumgaqo woxinzelelo lwe-vacuum umahluko ngonyuso lwamandla, olusetyenziselwa ukutyhala isilinda esilawula ibrake.Uxinzelelo lwehydraulic oluveliswa yi-brake master cylinder isebenzisa i-liquid incompressible transmission effect, ethi idluliselwe kwi-sub-cylinder nganye nge-hose ye-brake, kwaye uxinzelelo lwandiswa "ngumgaqo wePascal" ukutyhala ipiston ye-sub-cylinder. ukwenza amandla kwi-brake pads.“Umthetho kaPascal” (uMthetho kaPascal) uthetha ukuba uxinzelelo lolwelo nakweyiphi na indawo kwisikhongozeli esivaliweyo siyafana.
Uxinzelelo lufunyenwe ngokwahlula amandla asetyenzisiweyo kwindawo yokufumana amandla.Xa uxinzelelo lulingana, sinokusebenzisa ukutshintsha umlinganiselo weendawo ezisetyenzisiweyo kunye nokunyanzeliswa kokufumana amandla ukuphumeza umphumo wokukhulisa amandla (P1 = F1 / A1 = F2 / A2 = P2) .Isetyenziswa kwinkqubo yebrake, umyinge woxinzelelo lwe-master cylinder ukuya kwi-cylinder ngumlinganiselo wendawo yepiston ye-master cylinder ukuya kwindawo yepiston yesilinda.
Ixhotyiswe nge: ABS
I-ABS: Inkqubo yeBrake yokutshixa, njengoko negama lisitsho, yi “Anti-lock Brake System”.Wonke umntu uyazi ukuba eyona mpembelelo inkulu ye-braking yenzeke kwangoko phambi kokuba amatayara atshixiwe.Ukuba i-braking force inokugcinwa ngokulinganayo kunye ne-friction yetayara, umphumo omkhulu wokuqhawula uya kufumaneka.Xa i-braking force ye-brake inkulu kunokukhuhla kwetayara, kuya kubangela ukuba ivili litshixeke.Lakuba ivili litshixiwe, ukukhuhlana phakathi kwetayara kunye nomhlaba kuya kutshintsha ukusuka “kwi-static friction” ukuya “kwi-dynamic friction”.Akukhona kuphela ukungqubuzana kuncitshiswe kakhulu, kodwa i-steering ilahlekile.Ukukwazi ukulandela umkhondo.Ngenxa yokuba ukutshixa itayara kusisiphumo sokuthelekisa amandla okuqhobosheka kunye namandla okukhuhlana phakathi kwetayara nomhlaba, oko kukuthi, umda wokuba itayara litshixekile ngelixa imoto ibaleka kuxhomekeke kwiimpawu zetayara. ngokwayo, imeko yendawo yendlela, i-engile yokumisa, kunye noxinzelelo lwetayara.
Iimpawu zenkqubo yokunqunyanyiswa "zihluke kumaxesha ngamaxesha".I-ABS isebenzisa izinzwa zesantya sesithuthi ezifakwe kumavili amane ukumisela ukuba amatayara atshixiwe, ukuphelisa izinto ezingaqinisekanga zeemvakalelo zomntu, kunye nokulawula ngokuchanekileyo ukukhutshwa kwangethuba koxinzelelo lwehydraulic ye-cylinder yebrake ukuthintela iziqhoboshi ukuba zingatshixwa..Uninzi lwe-ABS yangoku ithatha uyilo olunokuthi lunyathele ngokuqhubekayo kwaye lukhulule amaxesha angama-12 ukuya kuma-60 ngesekhondi (12 ~ 60 Hz).Xa kuthelekiswa namaxesha ama-3 ukuya kuma-6 abagqatswa abachwepheshile, linqanaba eliphezulu lokusebenza.
Okukhona kuphezulu ukunyathela ukunyathela, kokukhona Amandla okuqhobosha anokugcinwa emphethweni kufutshane nomda.Ukuchaneka kunye nokuthembeka okunokuthi i-ABS ikwazi ukufikelela kuyo idlulile imida yabantu, ngoko sithi: I-ABS iyona nto ixabisa kakhulu isixhobo xa uthenga imoto.Ngokukodwa ingozi enxulumene ne-Air-Bag.
