I-Drum Brake Operation

Namuhla, amabhuleki avame kakhulu esiwathola emotweni yethu yi amabhuleki ama-disc. Nokho, izimoto eziningi namanje ifakwe amabhuleki esigubhu ku-asi yangemuva. Ezinye izimoto zize zibe nazo zombili izinhlobo, amabhuleki ediski angemuva, asetshenziswa njengebhuleki lesevisi, namabhuleki ezigubhu angemuva, asetshenziselwa ukupaka kuphela.

Amabhuleki esigubhu esiwaziyo namuhla, Zasungulwa ngo-1902 nguLouis Renault., kodwa kwaze kwaba ngo-1930 lapho kwethulwa khona ukusebenza kwamabhuleki nge-hydraulic. Namuhla, sizobona izici zamabhuleki ezigubhu, ukusebenza kwawo kanye izinkinga ezingenzeka.

I-Drum Brake Operation

Umgomo wokusebenza kwalolu hlobo lwamabhuleki ngu Kulula kakhulu. Izicathulo zamabhuleki zicindezela ngaphakathi kwesigubhu ukuze zimise ukunyakaza ngokungqubuzana. Okungeyona into engaphezu kokuguqula amandla e-kinetic abe ukushisa.

Izingxenye zayo zisebenza kanje: uma sicindezela i- i-brake pedal, i-hydraulic system ithwala i i-brake fluid kuze kube isigqoko se-bowler noma izigqoko ze-bowler, okuyinto ngenxa pistons yayo press the izicathulo ngokumelene ne i-tambor. Uma siyeka ukunyathela i-pedal, imithombo yokubuya ihlukanisa izicathulo nesigubhu.

Izingxenye

I-Los izisekelo zokubopha isigubhu Izicathulo, i-hydraulic cylinder, iziphethu, i-lever yokulungisa kanye nesigubhu ngokwaso. Uma kugqokwa amabhuleki ezigubhu awawagqoki njengamabhuleki amadisc. Leli qiniso lingathonywa kakhulu yiqiniso lokuthi zitholakala ku-axle yangemuva, lapho imoto ingathandi ukubhuleka kakhulu njengangaphambili.

Izinyawo

Ngokufanele uqinise isigubhu kusuka ngaphakathi, izicathulo anesimo esigobile ukuze uvumelane nesimo sakho. Ngokuvamile kwenziwa ngaphakathi insimbi futhi zimbozwe yi i-ferodo linings, okuyizona ezicindezelwa isigubhu.

Njengoba behlanganiswe isigubhu i ukushintsha izicathulo kuyinkimbinkimbi. Kufanele ususe isigubhu ukuze ufinyelele ithemu lapho zinamathiselwe khona. Khona-ke kufanele ususe wonke ama-rivets ayibambe endaweni.

Isilinda seHydraulic noma isilinda

Izitsha noma amasilinda yizici ukuthi gcwalisa nge-brake fluid, okucindezelayo kubangela i izibhamu aphume futhi aphushe izicathulo aze afike esigubhu. Ngokuvamile banamapiston amabili, elilodwa ohlangothini ngalunye, ukusunduza izicathulo ezimbili.

Imithombo yokubuyisela

Bangamatheku aphethe buyisela izinyawo endaweni yazo yokuqala lapho singalibambi ibhuleki. Kufanele baqine ngokwanele ukuze benze umsebenzi wabo, kodwa bangabi namandla kangangokuthi bangene endleleni yokubhuleka.

ukulungisa i-lever

Uyena ophethe lungisa ibanga ukusuka ezicathulweni kuya kusigubhu njengoba i-ferodo linings igqoka. Ngaleyo ndlela akumele badlulele phambili ukuze bafinyelele isigubhu. Okuthile okungathinta ikhono lakho lokubhuleka.

Isigubhu

Ikhamera ye-360

Lona ucezu ukuthi ihlanganisa lonke uhlelo lwamabhuleki futhi? ithola ukucindezela kwezicathulo. Ngenxa yalesi sizathu, igxilwe kuhabhu yesondo ukuze ijikeleze nayo, kuyilapho izicathulo ze-brake nezinye izingxenye zinamathiselwe ku-fixed plate, eboshelwe ku-spindle.

Plato

Yilapho i- izingxenye zangaphakathi zokubopha isigubhu: amasilinda, iziphethu, i-lever yokulungisa nezicathulo.

Izinhlobo zamabhuleki ezigubhu

I-Simplex

Lolu uhlelo lwamabhuleki esigubhu kulula kakhudlwana. Inesilinda kuphela esinomthwalo wokucindezela izicathulo ngokumelene nesigubhu. Ngokuvamile itholakala engxenyeni engenhla yalezi, kuyilapho zisekelwa ingxenye yazo engezansi esisekelweni.

Lolu hlelo lune-a ukuphazamisa, ukuthi abanye abafana ukuphuka kwesigubhu bazamile ukuxazulula. Njengoba izicathulo zithinta kuphela phezulu kwesigubhu, i-braking ayisebenzi kakhulu. Ngaphezu kwalokho, ukujikeleza kwesigubhu kubangela ukuthi isicathulo esisohlangothini lwesiqondiso sokuhamba sicindezele kanzima (isicathulo esiyinhloko), kuyilapho enye ngakolunye uhlangothi ingakwazi ukwenza umsebenzi wayo (isicathulo sesibili).

Duplex

Ukuze ugweme lokhu, uhlelo lwe-Duplex lunayo izitsha ezimbili ezicindezela amaphedi ukusuka phezulu nangaphansi, okuvumela ukuthi kube khona ukuxhumana okwengeziwe kwephedi futhi bobabili bangasebenzisa amandla afanayo okubhuleka. Ngakho-ke kulesi simiso, zombili izicathulo eziyinhloko. Okubi ukuthi ngokuthola ukungqubuzana okwengeziwe, ibhuleki yesigubhu nayo ishisa kakhulu.

I-Twinplex

Ngalolu hlelo, kufunwa lokho izicathulo ezimbili ziyinhloko ohlangothini olulodwa lokuhamba kanye nesesibili kwenye. Izicathulo zinamathele ezintantayo, ngakho-ke indawo yazo iyanyakaziswa ukuze yonke indawo yazo ithinte isigubhu.

I-Duo-servo

Iwuhlobo lwamabhuleki esigubhu afana kakhulu ne-Duplex, kodwa izicathulo zihamba ngesilinda phezulu bese zidudulana nge shayela induku komunye. Lolu hlelo lukuvumela ukuthi ube namandla amakhulu okubhuleka.

I-Drum Brake Vs. I-Disc Brake

Nakuba isigubhu saphuka isetshenziswa ngaphansi kakhulu kunediski, akuzona zonke ezimbi kulesi simiso. Nazi izinto ezinhle nezimbi zazo zombili lezi zinhlelo:

Amabhuleki esigubhu

buhle:

• eshibhile kokubili ekwenziweni kwayo nasekugcinweni kwayo
• ukugqunywa, abakwazi ukufaka izakhi eziwohlokayo. Into engenzeka kuma-disc brakes. Isibonelo, ukuthi phakathi kweShayina phakathi kwe-disc nama-pads, ukuthi uma sibhuleka kuzowohloka zombili izingxenye.

Umthengi:

• ukumelana kancane nokukhathala ngoba ukugqunywa kuphole kancane
• ushintsho yezicathulo kuyinto more complex ukuthi i ushintsho lwe-disc brake pad
• Ukusetshenziswa ngendlela engafanele kwama-linings kuye ngohlobo lwebhuleki yesigubhu.

Amabhuleki eCeramic noma e-carbon-ceramic: okuhle/nobubi, amanani nezinhlobo

Amabhuleki ediski

buhle:

• ukwanda kwamandla okupholisa. Okuyinikeza ukumelana okukhulu nokukhathala futhi ngakho-ke ivumela ukuthi yenziwe ngaphansi kwemizamo emikhulu ngaphandle kokulahlekelwa amandla amaningi ngenxa yokushisa okweqile.
• ushintsho lamaphilisi yi kulula kakhudlwana ukuthi kumabhuleki esigubhu
• amabhuleki afanayo kungakhathaliseki ukuthi uhamba ngakuphi. Into esemabhulekini esigubhu ayinjalo, kuya ngohlobo okuyilo.

Umthengi:

• ibhuleki lokupaka liyinkimbinkimbi ukuthi kumabhuleki esigubhu
• njengoba i-braking surface incane, izinga lokushisa liphakeme. Okuthile okunxeshezelwa ezimotweni ezisebenza kahle ezinama-multi-piston brake discs
• idinga ingcindezi eyengeziwe ukuze ibhuleki, njengoba ngokungafani namabhuleki esigubhu, ayinawo umphumela onika amandla.

I-Drum Brake Maintenance

Ukugcinwa kwebhuleki yesigubhu liyivelakancane kakhulu, ngoba aguga angaphansi kwama-disc. Ikakhulukazi uma zikwi-asi yangemuva, ngoba lapho kufanele zimelane kuphela phakathi kuka-25 no-30% we-braking. Ngaphezu kwalokho, izicathulo zinendawo enkulu yokuxhumana, ngakho ziguga kancane kancane.

I-elementi evame ukushintshwa yi- i-hydraulic cylinder. Le cylinder ingavuza i-brake fluid futhi, uma ingena ohlelweni, ingamanzisa izicathulo, iphazamise ukusebenza kahle kwamabhuleki.

Ngokuqondene nezakhe i-tamborKwenzeka okufanayo nangama-brake disc. Kufanele zishintshwe kancane kakhulu, ngakho ingahlala impilo yemoto. Ngezinye izikhathi, zingalungiswa ukuze izicathulo ezintsha zilingane kahle. Nakuba lokhu kusebenza akuvamile ukwenziwa namuhla.

intengo yokushintsha amabhuleki esigubhu

Intengo yamabhuleki ezigubhu incane kunaleyo yamabhuleki ediski. Zonke izingxenye zingabiza phakathi kwama-euro angama-50 noma ayi-100 kumamodeli ajwayelekile. Yize leyo ntengo ingaba phezulu kakhulu ezimotweni ezinkulu ezifakwe lolu hlobo lwamabhuleki. Okuthile okujwayelekile kuyo yonke indawo noma Phakamisa, ezidinga isistimu yamabhuleki engakwazi ukuthola uthuli noma amatshe.

Izinkinga ezingenzeka zamabhuleki esigubhu

Elinye lamaphutha esingawathola ohlelweni lwe-drum brake ukulahlekelwa ukusebenza kahle. Ngenxa yokubhuleka okulandelanayo, izinga lokushisa lomhlangano liyakhuphuka futhi, njengoba isistimu evaliwe, inobunzima bokupholisa futhi umuntu omaziyo angavela ikhula.

Kungase kwenzeke nakithi ukuthi unyawo luqhelelane nokusekelwa kwalo, ngalo isondo liyabhajwa. Kulesi simo kungase kudingeke ukuthi ushintshe izicathulo noma u-riveting endala, uma kungenzeka. Uma kungenjalo, kuzofanele kushintshwe yonke ikhithi ye-drum brake ngenxa yokulimala kwesindala.
