Kwiimoto, iibhasi kunye nezinye izixhobo ezinamabhuleki asebenza nge-pneumatically, ukuhanjiswa kwamandla ukusuka kwigumbi lokuqhawula ukuya kwiipads kwenziwa ngendlela ekhethekileyo-i-lever yokulungelelanisa.Funda konke malunga neelevers, iintlobo zazo, ukuyila kunye nokusebenza, kunye nokukhetha kwazo kunye nokutshintshwa, funda inqaku.
Yintoni i-lever yokulungisa i-brake?
Ukulungelelanisa i-lever ye-brake ("i-ratchet") - iyunithi yeebhuleki zevili zezithuthi ezixhotyiswe nge-pneumatically operating system;Isixhobo sokudlulisa i-torque ukusuka kwigumbi le-brake ukuya kwi-brake pad drive kunye nokulungelelanisa (i-manual okanye ngokuzenzekelayo) i-gap yokusebenza phakathi kwe-friction linings ye-pads kunye nomphezulu we-drum ye-brake ngokutshintsha i-angle ye-knuckle yokwandisa.
Uninzi lweemoto zanamhlanje ezinamavili anzima kunye nezixhobo ezahlukeneyo zeemoto zixhotyiswe ngenkqubo yebrake esebenza ngepneumatically.Ukuqhuba kweendlela ezifakwe kumavili kwinkqubo enjalo kuqhutyelwa ngoncedo lwamagumbi okuqhawula (TC), ukubethelwa kwentonga engakwazi ukutshintsha okanye ukutshintsha kwimida emxinwa kakhulu.Oku kunokukhokelela ekusebenzeni kakubi kwebrake xa iipakeki zigugile - ngaxa lithile, uhambo lwentonga alusayi kuba sanele ukukhetha umgama owandisiweyo phakathi komgca we-lining kunye nomphezulu wegubu, kwaye ukunyathela nje akuyi kwenzeka.Ukuyicombulula le ngxaki, iyunithi eyongezelelweyo iyangeniswa kwiibhuleki zevili ukutshintsha nokugcina umsantsa phakathi kwemiphezulu yala macandelo - i-lever adjustment lever.
I-lever yokulungisa inemisebenzi emininzi:
● Uqhagamshelo lomatshini lwe-TC kunye neknuckle yokwandisa ukwenzela ukuhambisa amandla kwiipads ukwenza i-braking;
● Ukugcinwa kwezandla okanye okuzenzekelayo komgama ofunekayo phakathi kweelini zokukhuhla kunye nomphezulu wokusebenza wedramu yebrake ngaphakathi kwemida emiselweyo (ukukhethwa kwesithuba ngokuguga kancinci kweelini);
● Uhlengahlengiso lokucocwa ngesandla xa ufaka iilenki ezitsha zokukhuhlana okanye igubu, emva kokuba uqhoboshele ixesha elide xa uqhuba ukuhla nakwezinye iimeko.
Ngombulelo kwi-lever, i-gap efunekayo phakathi kweepads kunye ne-drum igcinwe, ephelisa isidingo sokulungelelanisa i-stroke ye-brake rod ye-brake kwaye iphazamise ezinye iindawo zeendlela zokuqhawula.Le yunithi idlala indima ebaluleke kakhulu ekuqinisekiseni ukusebenza ngokuqhelekileyo kwenkqubo yokuqhokra kwaye, ngenxa yoko, ukhuseleko lwesithuthi.Ngoko ke, ukuba i-lever ingasebenzi kakuhle, kufuneka ithathelwe indawo, kodwa ngaphambi kokuthenga inxalenye entsha, kufuneka uqonde ukuyila, umgaqo wokusebenza kunye neempawu zokulungelelanisa.
Iintlobo, uyilo kunye nomgaqo wokusebenza kwe-lever yokulungisa i-brake
Iindidi ezimbini zohlengahlengiso zisetyenziswa kwizithuthi:
● Ngomlawuli wezandla;
● Ngomlawuli ozenzekelayo.
Uyilo olulula kakhulu luyi-levers kunye nomlawuli we-manual, eziqhelekileyo kwiimoto kunye neebhasi zeminyaka yokuqala yokuvelisa.Isiseko sale nxalenye ngumzimba wensimbi ngendlela ye-lever enesandiso esisezantsi.I-lever inomngxuma omnye okanye ngaphezulu wokubamba igumbi lokuqhawula kwifolokhwe.Kukho umngxuma omkhulu ekwandisweni kokufaka igiya yeentshulube eneendawo zokubeka ngaphakathi, intshulube ene-axis i-perpendicular to the lever body.I-axis yombungu kwelinye icala iphuma emzimbeni, kwisiphelo sayo sangaphandle kukho i-turnkey hexagon.I-axle igxininiswe ekujikeni ngeplate yokutshixa, ebanjwe ngebholithi.Ukongezelela, i-lock yebhola yebhola inokufumaneka kwi-lever - inikezela ukulungiswa kwe-axis ngenxa yokugxininiswa kwebhola yensimbi kwiindawo ezijikelezayo kwi-axis.Ukunyanzeliswa kwebhola kunokulungiswa ngesithinteli esinemisonto.Indawo yokufakela i-gear gear ye-slot-gear kunye ne-worm ivalwe kumacala omabini kunye nezigqubuthelo zetsimbi kwiirivets.Kwindawo yangaphandle yendlu kukho igrisi efanelekileyo yokubonelela nge-lubricant kwi-gear kunye ne-valve yokukhusela ukukhutshwa kwezixa ezigqithisileyo zegrisi.
I-lever yokulungelelanisa kunye nohlengahlengiso lwezandla
I-auto-adjusting lever inesixhobo esinzima ngakumbi.Kwi-lever enjalo kukho iinxalenye ezongezelelweyo-i-ratchet cam mechanism, kunye nezibophelelo ezihambayo kunye nezisisigxina ezidityaniswe ne-worm axis, eqhutywa yi-pusher esuka kwi-leash ebekwe kwicala lomzimba.
I-lever ene-automatic regulator isebenza ngolu hlobo lulandelayo.Ngomsantsa oqhelekileyo phakathi kweepads kunye ne-drum, i-lever isebenza ngendlela efanayo njengoko ichazwe ngasentla - idlulisela nje amandla kwifolokhwe ye-brake yegumbi ukuya kwi-knuckle yokwandisa.Njengoko iipads ziphela, i-lever ijikeleza kwi-angle enkulu, oku kulandelwa yintambo egxininisekile kwi-bracket.Kwimeko yokuguga ngokugqithisileyo kwe-linings, i-leash ijikeleza kwi-angle enkulu kwaye ijika i-clutch ehambayo nge-pusher.Oku, kukhokelela ekujikelezweni komatshini we-ratchet ngenyathelo elinye kunye nokujikeleza okuhambelanayo kwe-worm axis - ngenxa yoko, i-spline gear kunye ne-knuckle axis yokwandisa idityaniswe kuyo ijikeleza, kunye nomsantsa phakathi kweepads kunye igubu liyancipha.Ukuba ukujika kwesinyathelo esisodwa akwanele, ngoko ngexesha lokunyathela okulandelayo, iinkqubo ezichaziweyo ziya kuqhubeka de ukukhutshwa okugqithisileyo kuthathwe isampuli ngokupheleleyo.
I-lever yokulungelelanisa kunye nohlengahlengiso oluzenzekelayo
Ngaloo ndlela, i-lever ilungelelanisa ngokuzenzekelayo isikhundla se-brake pads ngokubhekiselele kwi-drum njengoko i-friction linings igugile, kwaye ukuya kukutshintshwa kwee-linings ayifuni ukungenelela.
Zombini ezi ntlobo zeziqhoboshi ziyinxalenye yeziqhoboshi zesondo zangaphambili nasemva, ngokuxhomekeke kuyilo, zinokuba nemingxuma enye ukuya kwesibhozo okanye ngaphezulu kwi-lever yohlengahlengiso olurhabaxa lweziqhoboshi ngokucwangcisa ngokutsha ifolokhwe ye-brake chamber rod okanye ukuyifakela. amagumbi eentlobo ngeentlobo.Ekubeni i-lever ibonakaliswe kwiimpembelelo ezimbi zendalo ngexesha lokusebenza, inika i-O-rings ukukhusela iindawo zangaphakathi kumanzi, ukungcola, iigesi, njl.
Imiba yokukhetha, ukutshintshwa kunye nokugcinwa kwe-lever yokulungisa i-lever
I-lever yokulungisa i-brake igugile kwaye ingasetyenziswa ngokuhamba kwexesha, efuna ukutshintshwa kwayo.Ngokuqinisekileyo, inxalenye inokulungiswa, kodwa namhlanje kwiimeko ezininzi kulula kwaye kuyabiza ukuthenga nokufaka i-lever entsha kunokubuyisela endala.Ukutshintshwa, kufuneka ukhethe i-levers kuphela kwezo ntlobo zifakwe kwimoto ngaphambili, nangona kunjalo, ukuba kuyimfuneko, ungasebenzisa i-analogues kunye nemilinganiselo efanelekileyo yokufakela kunye neempawu.Ukutshintsha i-lever ehlengahlengiswayo ngesandla nge-lever ezenzekelayo kwaye ngokuphambeneyo kwiimeko ezininzi akunakwenzeka okanye kufuna ukuguqulwa kwendlela yevili lokuqhawula.Ukuba uceba ukufaka i-lever yomnye imodeli okanye komnye umenzi, ngoko kufuneka utshintshe zombini i-levers kwi-axle ngokukhawuleza, ngaphandle koko ukulungelelaniswa kwe-gap kumavili asekunene nasekhohlo kungenziwa ngokungalingani kunye nokuphulwa kweebhuleki.
Ukufakwa kwe-lever kufuneka kuqhutywe ngokuhambelana nemiyalelo yokulungiswa nokugcinwa kwesi sithuthi.Njengomthetho, lo msebenzi uqhutyelwa ngamanyathelo amaninzi: i-lever ifakwe kwi-axis ye-knuckle ekhulayo (ekufuneka iqhawule umtshato phantsi kwesenzo semithombo), ngoko i-axis ye-worm ijikelezwa ngokuphambene ne-clockwise kunye nesitshixo de umngxuma kwi-lever ihambelana nefoloko yentonga ye-TC, emva koko i-lever igxininiswe ngefoloko kwaye i-axis ye-worm igxininiswe kunye neplate yokugcina.
Indlela yokuqhawula ivili kunye nendawo yelever yokulungelelanisa kuyo
Izixhobo zolu hlobo zifana noyilo kwiimpawu ezixutyushwa ngasentla, kodwa zineenkcukacha ezongezelelweyo - uphondo oluthe ngqo ("uphondo"), i-spiral ("cochlea") okanye olunye uhlobo.Umva wophondo ubekwe kwicala le-membrane, ngoko ukungcangcazela kwe-membrane kubangela ukuba wonke umoya obekwe eluphondweni ungcangcazele - oku kubonelela ngokuphuma kwesandi sokwakheka kwembonakalo ethile, ithoni yesandi ixhomekeke kubude. kunye nomthamo wangaphakathi wophondo.
Eyona nto ixhaphakileyo yimiqondiso ye-compact "snail", ethatha indawo encinci kwaye inamandla amakhulu.Kancinci kancinane izibonakaliso "zephondo", ezithi, xa zandisiwe, zinembonakalo ekhangayo kwaye zingasetyenziselwa ukuhlobisa imoto.Kungakhathaliseki ukuba luhlobo luni lophondo, ezi ZSP zinazo zonke iingenelo zeempawu zokungcangcazela eziqhelekileyo, eziqinisekisa ukuthandwa kwazo.
Uyilo lwesandi senwebu yesigodlo
Kwixesha elizayo, i-lever ene-regulator manual kufuneka isetyenziswe - ngokuguqula imbungu, ulungise umgama phakathi kweepads kunye ne-drum.I-lever ene-automatic regulator idinga ungenelelo lwezandla kwiimeko ezimbini: xa utshintsha i-friction linings kunye nakwimeko ye-jamming ye-brakes ngexesha lokuhla kwexesha elide (ngenxa yokuxhatshazwa, i-drum iyatshisa kwaye yanda, okukhokelela ekwandeni kokukhutshwa i-lever iyanciphisa ngokuzenzekelayo i-gap, kodwa emva kokuyeka, i-drum ipholisa kwaye iyancipha, nto leyo inokukhokelela kwi-jamming of brakes).Kwakhona ngamaxesha athile kuyimfuneko ukongeza i-lubricant kwiilevers ngokusebenzisa izifakelo zegrisi (phambi kokukhama i-lubricant ngevalve yokhuseleko), ngokuqhelekileyo ukuthambisa kwenziwa ngexesha lokugcinwa kwexesha lonyaka kusetyenziswa izithambiso zegrisi zeempawu ezithile.
Ngokukhetha okufanelekileyo, ukufakwa okufanelekileyo kunye nokugcinwa kwangethuba kwe-lever, iibhuleki zamavili ziya kusebenza ngokuthembekileyo nangokufanelekileyo kuzo zonke iimeko zokusebenza.
