Indima ephambili yediski yebhuleki yangaphambili kwinkqubo yokubhuleka kweemoto
Kwinkqubo yokuqhobosha iimoto, idiski yebhuleki yangaphambili yenye yezona zinto zibalulekileyo eziqinisekisa ukhuseleko lokuqhuba, kwaye ithwala uxinzelelo olukhulu lokuqhobosha kunediski yebhuleki yangasemva. Ngokwezibalo, ngexesha lokuqhobosha iimoto, idiski yebhuleki yangaphambili kufuneka ithwale i-70%-80% yamandla okuqhobosha. Oku kungenxa yempawu zomzimba zokuba iziko lomxhuzulane wesithuthi litshintshela phambili ngexesha lokuqhobosha - ubunzima benxalenye engaphambili yesithuthi bunyuka ngequbuliso bufikelele kwi-70% yobunzima besithuthi siphela. Idiski yebhuleki yangaphambili kufuneka iguqule amandla e-kinetic esithuthi abe ngamandla obushushu ngokusebenzisa ukungqubana okunamandla aphezulu kunye nee-brake pads, oku kwenza ukuba isantya okanye ukuma ngokukhawuleza.
Umsebenzi wediski yebhuleki yangaphambili awupheleli nje "ekunciphiseni isantya"; ikwangumthwalo obalulekileyo wokusebenza okuzinzileyo kwenkqubo yokubhuleka. Liqonga eliphambili lokuguqula amandla e-kinetic, livelisa ubushushu ngokubhidliza ukuze kudliwe i-inertia yesithuthi; kwangaxeshanye, uninzi lweediski zebhuleki zangaphambili zamkela uyilo lwediski olunomoya, olunesakhiwo esingenanto esinokukhawulezisa i-convection yomoya kwaye sikhuphe ngokukhawuleza ubushushu obuphezulu obuyi-500-700℃ obuveliswa kukubhidliza, kuthintelwe ukungaphumeleli kweebhuleki okubangelwa kukuncipha kobushushu; ngaphezu koko, sisiphelo sokusebenza seenkqubo ezincedisayo ze-elektroniki ezifana ne-ABS, ezisebenzisana neesensa ukulungisa amandla okubhuleka ngexesha langempela ukuqinisekisa ukuba amavili awavaleki ngexesha lokubhidliza okungxamisekileyo kunye nokugcina uzinzo lolawulo lwesithuthi.
Xa kuthelekiswa nediski yebrake yangasemva, uyilo lwediski yebrake yangaphambili lunika ingqalelo engakumbi ekuhlengahlengiseni ukusebenza. Ngokwesiqhelo, ububanzi bediski yebrake yangaphambili bukhulu, njengediski yebrake yangaphambili yeCorolla enobubanzi obuyi-287mm, ngelixa idiski yangasemva iyi-255mm kuphela. Indawo enkulu yokungqubana inokubonelela ngamandla okubhuleka; izixhobo zisebenzisa kakhulu i-HT200 okanye i-HT250 grey cast iron, kwaye ezinye iimodeli eziphezulu zisebenzisa i-alloy cast iron ukuqinisekisa amandla aneleyo kunye nokumelana nokuguguleka kumaqondo obushushu aphezulu kunye noxinzelelo oluphezulu; ngokwesakhiwo, uninzi lweediski zebrake zangaphambili zixhotyiswe ngee-calipers ze-double-piston, ezinokusebenzisa amandla okubhuleka ngokulinganayo kwaye zilungelelanise neemeko zokubhuleka eziqhelekileyo ezifana nokuhamba edolophini kunye nokuqhuba entabeni.
Iimpazamo eziqhelekileyo kunye nezizathu zediski yebhuleki yangaphambili
Ukungcangcazela kweebhuleki kunye nengxolo engaqhelekanga
Le yeyona nto ixhaphakileyo ebonakalisa iimpazamo kwidiski yebrake yangaphambili, ikakhulu ngenxa yokuphambuka komgangatho womphezulu wediski. Ngokwemigangatho yoshishino, xa impazamo yomgangatho womphezulu osebenzayo wediski yebrake idlula i-0.05mm, indawo yoqhagamshelwano phakathi kwephedi yebrake kunye nomphezulu wediski iya kutshintsha rhoqo ngokujikeleza kwediski, nto leyo ebangela ukuguquguquka kwe-torque yebrake, kwaye emva koko ibangele ukungcangcazela kwevili lokuqhuba kunye nokungcangcazela komzimba. Ukuqhambuka rhoqo okungxamisekileyo yenye yezona zizathu ziphambili. Ngexesha lokuqhambuka, ubushushu bomphezulu wediski bunyuka bufikelele kwi-600℃, kwaye umphezulu wediski uthambekele ekuguqukeni kobushushu phantsi kobushushu obuphezulu; ukuguguleka kwexesha elide kwemiqolo, amanyathelo, okanye ukuqina okungafanelekanga kwe-torque ngexesha lokufakwa nako kunokwenza kube nzima ukuphambuka komgangatho womphezulu.
Izizathu zengxolo engaqhelekanga zahlukile: umhlwa okanye ukuqokelelwa kokungcola kumphezulu wediski yebrake, xa ikhuhla kwi-brake pad, kuya kuvelisa isandi esibukhali sokukrwela sesinyithi; xa i-brake pad igugile ukuya kubukhulu obumiselweyo, ipleyiti yesinyithi engasemva iya kudibana ngqo nediski, ikhuphe ingxolo engaqhelekanga eqhubekayo; ukongeza, ii-brake disc kunye nee-hub screws ezikhululekileyo, okanye ukulungiswa okungafanelekanga kwenkqubo yebrake, okubangela umgama ongaqhelekanga phakathi kwe-brake pad kunye nomphezulu wediski, kunokubangela ingxolo engaqhelekanga eyenzeka rhoqo.
Ukwehla kobushushu kunye nokwehla kokusebenza
Ngexesha lokuqhuba ngokuqhubekayo okanye ukubhuleka rhoqo ngexesha likaxakeka, idiski yebhuleki yangaphambili ihlala ikwimeko yobushushu obuphezulu ixesha elide. Ukuba ubushushu abufiki ngexesha elifanelekileyo, kuya kwenzeka into yokubola kobushushu - i-torque yokubhuleka iyancipha kakhulu, i-pedal yebhuleki iyathamba, kwaye umgama wokubhuleka uyandiswa. Oku kungenxa yokuba i-coefficient yokungqubana kwezinto zediski yebhuleki iyancipha phantsi kobushushu obuphezulu, kwaye umphezulu wediski unokuba nemingxunya yobushushu, nto leyo ebangela ukuba ukusebenza kokubhuleka kube buthathaka ngakumbi. Ukuvaleka kwediski yomoya okanye umxholo wokufuma ogqithisileyo kulwelo lwebhuleki (ngaphezulu kwe-3%) okukhokelela ekunciphiseni ukusebenza kakuhle kokubhuleka kobushushu zizizathu eziqhelekileyo ezingathanga ngqo zokubola kobushushu.
Ukuguga okugqithisileyo kunye nobukhulu obungonelanga
Ubomi obuqhelekileyo bokuguguleka kwediski yebhuleki yangaphambili bumalunga neekhilomitha eziyi-8-120,000, kodwa ukubhukha rhoqo ngexesha likaxakeka, ukuqhuba ixesha elide kwindawo exineneyo, kunye neminye imikhwa emibi yokuqhuba kuya kuyinciphisa kakhulu ubomi bayo benkonzo. Xa ubukhulu bediski yebhuleki buguguleka bufikelela ngaphantsi kwe-1/3 yobukhulu bokuqala (ngesiqhelo ubukhulu bokuqala buyi-22-30mm, kwaye kufuneka ilumke xa iguguleka bufikelela ngaphantsi kwe-22mm), amandla ayo aya kuncipha kakhulu, kungekuphela nje ukunciphisa impembelelo yokubhukha kodwa nokuqhekeka okunokwenzeka ngexesha lokubhukha, okubangela iingozi ezinkulu zokhuseleko. Ukongeza, ukuba izinto zephedi yebhuleki ziqinile kakhulu kwaye kukho izinto zangaphandle ezixutyiweyo, kuya kukhawulezisa ukuguguleka kwediski yebhuleki, kwenze imingxunya enzulu.
Ukuxilongwa kweengxaki kunye neengcebiso zokugcinwa kwemihla ngemihla
Xa ujongene nokusilela kwediski yebhuleki yangaphambili, kufuneka kulandelwe into ephambili xa kulungiswa iingxaki: Okokuqala, jonga imeko yomphezulu wediski uze ulinganise ukuba ithe tyaba usebenzisa isalathisi sokudayela. Ukuba ukuphambuka kudlula umgangatho, umaleko womphezulu we-0.5-1mm ungasuswa kusetyenziswa idiski yediski (ukubuyisela ukuba ithe tyaba), kwaye ukuba ukuguguleka kukhulu, kufuneka kutshintshwe; okwesibini, jonga ubukhulu bephedi yebhuleki. Ukuba ubukhulu obuseleyo bungaphantsi kwe-3mm, kutshintshwe kuyimfuneko. Kwangaxeshanye, qinisekisa ukuba izinto zephedi yebhuleki ziyafana nezo zediski yebhuleki; ekugqibeleni, jonga imeko ye-hydraulic yenkqubo yebhuleki. Tshintsha rhoqo ulwelo lwebhuleki (rhoqo emva kweminyaka emi-2 okanye iikhilomitha ezingama-40,000), uqinisekise ukuba umxholo womswakama ungaphantsi kwe-3%, kwaye ukhuphe umoya kwinkqubo.
Ngexesha lokulungiswa kwemihla ngemihla, kuphephe ukuhlamba imoto ngqo xa idiski yebrake ishushu ukuthintela ukuguquka kwediski okubangelwa kukutsha kakhulu; jonga ubukhulu kunye nokuthamba kwediski yebrake kanye kwikhilomitha ezingama-30,000, kwaye ulinganise ibhalansi yetayara kanye kwikhilomitha ezili-10,000 ukuthintela ukungalingani kwetayara ekubeni kubangele umonakalo omkhulu kwi-brake judder; phuhlisa imikhwa emihle yokuqhuba, unciphise ukuqhobosheka rhoqo ngexesha longxamiseko, kwaye usebenzise ukuqhobosheka kwenjini ukunceda ekunciphiseni isantya ngexesha lokwehla okude ukunciphisa umthwalo wediski yebrake yangaphambili.
