Drum mabhureki

Drum mabhureki ane shangu mbiri dzinotungamira.Mumwe anotungamirira asi mumwe achitevera.Kana motokari ichifamba, shangu dzose dziri mbiri dzinoita semitungamiri.Nekumashure, mapistoni ari muhumburumbira yega yega anoita seanotsika kumashure.Dual twin lead bhutsu dzine mapiston anotama kumativi ese.Rudzi urwu rwebhureki rinowanzo kuwanikwa kumashure kwerori diki.Kunyange zvazvo kusungirirwa kwe-sided-sided kunogona kuguma kune rimwe-sided load paforogo yepamberi, maviri-mapatya anotungamira shangu isarudzo iri nani kune motokari dzakawanda.

Drum brake system inoshandisa silinda inotenderera neshangu dzinokwesha panzvimbo inokweshana kuti mota inonoke.Shangu dzinoita kupesana nedhiramu kana pedal yaburitswa, ichigadzira hydraulic pressure.Kudhumhana uku kunoita kuti bhutsu dzemabhureki dziite kurira uye kunonoka mota.Izvi zvinonzi "self-applying."

Chimwe chikamu chedhiramu mabhureki ndiko kupera kwayo.An anchor abutment yakaiswa pane yekumashure-plate yakatarisana neiyo expander unit.Iyo anchor abutment inoshanda sehinge, iyo inoita kuti shangu dzirege kutenderera nedhiramu kana bhureki raiswa.Kune mhando mbiri huru dzeanchors: single-pini uye kaviri-pini.Rudzi rwekare rwunonyanya kuwanda mumotokari dzemagetsi.

Motokari yakatanga kushandisa mabhureki edhiramu yemazuva ano yaiva Maybach.Louis Renault akashandisa asbestos yakarukwa lining yedhiramu brake lining nekuti yaibvisa kupisa zvirinani kupfuura chero chinhu chipi zvacho.Dzimwe mota dzaishandisa mhando dzemadhiramu mabhureki.Mamodheru ekare aishandisa marevheti, tsvimbo, tambo, uye shangu dzemuchina.Mapiston aishandiswa neoiri muhumburumbira diki.Aya masisitimu emuchina aive akajairika kusvika kuma1980, asi dzimwe mota dzakaramba dzichidzishandisa.

Diski mabhureki

Musiyano uripo pakati peaya maviri madhiramu marudzi ndewekuti anoshanda pamusimboti mumwechete uye ese ari maviri anoshandiswa pamotokari imwechete.Munyaya ye disc mabhureki, zvisinei, dhisiki yakamira uye caliper inofamba-famba maererano ne rotor.Iyo yemukati brake pad inotsikirirwa padhisiki panguva yebhureki uye rekunze brake pad rinodhonzwa parotor.Munguva iyi, mabhureki mapedhi anopisa uye anomanikidzwa kurwisa disc.Iyi nzira inozivikanwa se "pad imprinting," iyo inobatsira kune braking simba.

Zvikamu zvinopisa zvemadhisiki zvinogona kusvika pakupisa kwakanyanya.Kana izvi zvikaitika, simbi inopinda shanduko yechikamu.Carbon musimbi inogona kudonha kubva musimbi uye kuumba kabhoni-heavy carbide matunhu.Cementite, zvisinei, chinhu chakasiyana pane simbi yakakandwa uye yakaoma zvakanyanya uye ine brittle.Iyo hainawo kutora kupisa zvakanaka, kukanganisa kuvimbika kwe disc.

Disc mabhureki anozivikanwawo se caliper mabhureki.Vanoshandisa hydraulic pressure kusunda shangu dzichitarisana nemukati medhiramu yebhureki.Aya mabhureki musanganiswa wemapistoni uye anogona kushandisa mapiston anosvika masere.Madhisiki mabhureki ndiyo yakajairika mhando yemabhureki madhiramu.Zvisinei, kune mamwe marudzi akawanda.Kana iwe uchitsvaga bhureki nyowani, disc mabhureki anogona kunge akakukodzera iwe.

Mabhureki edhisiki anosiyana nemabhureki edhiramu nenzira dzakawanda.Mabhureki edhisiki anoburitsa kupisa kwakanyanya uye kukweshana, zvinoreva kuti zvikamu zvawo hazvina hupenyu hurefu.Mukuwedzera, nhamba yezvikamu mu disc brake inowedzera mukana wekukundikana.Mabhureki edhiramu anogona kuita ruzha zvakare, kunyanya kana ari kushandiswa nevatyairi vasingazive zvavari kutaura nezvazvo.

Kuzvisunga mabhureki

Kune maviri akakosha ekuzvishandisa ega mabhureki emhando dzedhiramu: kukweshera-kushandisa uye kukwesha-kunwa.Iyo yekutanga inoshandisa friction-aplying zvishandiso kupa simba rekubhureki, iro rinoiswa kune pedal panguva inononoka-pasi.Madhiramu ega ega anoshandisa dhiramu kuisa simba, nepo friction-absorbing masisitimu anoshandisa rotor.Musiyano uripo pakati pemhando mbiri idzi dzemabhureki uri mumichina yavo.

Kana zvigubhu zvemabhureki zvinozvimisikidza zvichishandiswa kumashure, zvinobata mota kana huremu hwemotokari huchienda kushangu inotevedza.Izvi zvinogona kunge zvichikonzerwa nekutenuka kwemateru kana kudzosera kumashure mafambiro.Munyaya yekutungamirira-shangu mabhureki, shangu inotungamira iri pedyo nekuwedzera.Zvakakosha kupa ngwariro yakafanira pakukokorodza bhureki kana yadimburwa.Kutadza kuita izvi kunogona kutungamira kune kunotyisa bhureki uye kukiya kunobvira.

Mabhureki anokwenya anoshandisa friction-adhesive material kuisa simba padhiramu.Iyi friction-adhesion material inobatsira mabhureki kushandisa simba kuvhiri, asi inogona kukonzera kukanganisa uye kuzunguzika panguva yekubhureki.Madhiramu emabhureki anokwenya anogonawo kuita kuti mutyairi ashandise simba rakawanda pabhureki pedal pane zvaanoda kuti amise motokari.

Kuzvishandisa wega mabhureki madhiramu ane zvinhu zviviri zvikuru: iyo yekumashure-ndiro uye anchor abutment.Iyo anchor abutment, iyo iri pakatarisana neiyo expander unit, inoshanda sehinge yeshangu.Iyi back-plate inopa tsigiro ye cylinder expander uye inowanzogadzirwa ne ribbed steel.Iyo anchor abutment inoshandawo seguruva-nhoo yebhureki dhiramu uye shangu musangano.

Dzokai zvitubu

Chitubu chekudzoka chinhu chinofambiswa chinoshandiswa kubata shangu dzebhureki kumashure mushure mekunge silinda yevhiri yaburitsa kudzvanywa kubva kune braking system.Zvichienderana nemagadzirirwo ehurongwa, zvitubu zvekudzoka zvinogona kusungirirwa kune ese ari maviri anoteedzera uye anotungamira shangu kana anchored panzvimbo yepakati.Mamwe madhiramu mabhureki masisitimu anoshandisa chitubu chimwe chete uye mamwe anoshandisa refu, yakaomarara simbi bhaa yakabhenda kuita U chimiro.Migumo yezasi yechitubu yakabatana neshangu inoteedzera uye magumo ekumusoro eU chimiro anonamatira kune inotungamira shangu.

Shangu inotungamira inofamba ichienda kune imwe nzira yedhiramu kana bhureki raiswa, izvo zvinoita kuti shangu dzitsigire pamusoro pemukati wedhiramu nekumanikidza kukuru.Iyi servo mhedzisiro inozivikanwa seye-self-boosting maitiro.Silinda yevhiri inogara piston uye hydraulic pressure inosunda shangu dzichienda nechemukati medhiramu.Zvose zvitubu zvinodzoka zvinofanirwa kugadziriswa nguva dzose, saka zvakakosha kune inoshanda mabhureki system.

Chitubu chekudzoka uye mapistoni zvikamu zviviri zvakakosha zvedhiramu brake.Kana mabhureki achitsikirirwa, brake fluid inomanikidzwa kupinda mucylinder yevhiri kusunda shangu dzebhureki padhiramu.Zvitubu zvinodzosa zvidhonze kuti vadzokere kunzvimbo dzavo dzekuzorora.Kana bhureki raburitswa, zvitubu zvekudzoka gadzirisa shangu dzemabhureki kumashure.Chitubu chekudzoka ndicho chikamu chekupedzisira chebhureki system, uye ndiyo inonyanya-inoshandiswa mhando.

Kunyange zvazvo piston uye zvitubu zvekudzoka zvinoshanda kuisa bhureki, chigubhu hachikurumidzi kubatana neshangu.Dzinoda kutanga dzakatsikirirwa bhutsu dzisati dzaenda kudhiramu.Hybrid disc/drum systems, kune rumwe rutivi, inongobhureka nemadhisiki pane light pedal pressure.Iyi mhando yebraking system inoda yakakosha metering valve kudzivirira iyo hydraulic pressure kuti isasvike kumberi calipers kusvika matsime ekudzoka akundwa.

Brake pads

Kune mhando mbiri huru dzemabhureki madhiramu: fixed uye slack.Zvichienderana nerudzi rwemotokari, iyo yekupedzisira inoshandiswa mumotokari dzinorema.Ose ari maviri akagadzirwa kuti ashande mukudzivirira kukweva kwevhiri-cylinder uye kuderedza ruzha rwemotokari.Fixed drums inoratidzira rotor uye disc-yakafanana neshangu-expanders inowanzoitika mumotokari.Zvisinei, marudzi ose ane maitiro akasiyana.

Semuenzaniso, madhiramu anowedzera mukati ane simba rekumira rakaderera pane mamwe awo esimbi nesimbi.Otomatiki magiya mabhokisi anowanzo anofarira mukati-anowedzera madhiramu, nepo madhiramu achisarudzirwa magiya mabhokisi.Drum mabhureki anowanzo shandiswa pamavhiri ekumashure emotokari, uye anozadzisa disc system kumberi.Iyo mechanic hand-brake inopindirana nemabhureki edhiramu.

Kana yakadzvanywa padhiramu, shangu inotungamira inofamba ichienda kune imwe nzira sedhiramu, uye shangu yekutevera inoenda kune imwe nzira.Mhedzisiro iyi inozivikanwa se servo athari, uye inobatsira shangu kudzvanya kurwisa chigubhu nesimba guru.Mune yakajairwa mabhureki system, bhutsu inotungamira inoenda kumberi kwakanangana nedhiramu, uku iyo inoteedzera shangu ichidzokera kumashure.Kazhinji, mabhureki edhiramu anoiswa kumashure kwemotokari dzinotakura vanhu.

Ndeapi maviri anonyanya kufarirwa mabhureki madhiramu, uye anosiyana sei?Kuti udzivise matambudziko, mabhureki anofanirwa kuongororwa nguva nenguva.Kutadza kuita izvi kunogona kukonzera kupera kwemabhureki.Brake fade inokonzerwa nekupisa kwezvikamu zvebhureki, uye kusanganiswa kwezvinhu izvi.Iyo yemukati-inowedzera mabhureki madhiramu, semuenzaniso, anogona kuwedzera dhayamita nekuda kwekuwedzera kwekupisa.Kuripa, shangu dzinofanira kufamba mberi kana kuti mutyairi anofanira kuisa brake pedal zvishoma.
