Kungani i-pedal yebhuleki yathamba ngemva kokushintsha ama-brake pads
Okuqukethwe
Ngisho nento elula njengokushintsha ama-brake pads, empeleni, ukungenelela kokulungisa ohlelweni lokuphepha olubaluleke kakhulu. Udinga ukwazi zonke izinto ezicashile nemiphumela engenzeka yenqubo, abaningi abangayibukeli phansi, futhi ngemva kokuqeda umsebenzi, bangase bamangale ngemiphumela.
Enye yezinkinga ezivele ukwehluleka (ukuthamba) kwe-pedal ukuya phansi esikhundleni se-viscous evamile kanye ne-braking enamandla.
Kungani i-pedal ihluleka ngemva kokufaka amaphedi
Ukuze uqonde ingqikithi yalokho okwenzekayo, kubalulekile ukuqonda ngokucacile, okungenani ezingeni lomzimba, ukuthi uhlelo lwe-brake yemoto lusebenza kanjani. Yini ngempela okufanele yenzeke ngemva kokucindezela i-pedal, nokuthi kwenzekani ngemva kwezenzo eziyiphutha.
I-pedal rod ngokusebenzisa isilinda esidonsa amanzi kakhulu idala ingcindezi emigqeni yamabhuleki. Uketshezi alukwazi ukucindezelwa, ngakho-ke amandla azodluliselwa ngamasilinda esigqila kuma-calipers kuma-brake pads futhi azocindezela ngokumelene nama-discs. Imoto izoqala ukwehla.
Amandla okubamba amaphedi kufanele abe abalulekile. I-coefficient of friction of linings on cast cast iron or steel of the disk ayinkulu kakhulu, futhi amandla okushayisana anqunywa ngokunembile umkhiqizo wawo ngamandla acindezelayo.
Kusuka lapha, ukuguqulwa kwe-hydraulic yesistimu kubalwa, lapho ukunyakaza okukhulu kwe-pedal kuholela ekuhambeni kwe-pad encane, kodwa kukhona ukuzuza okuphawulekayo kwamandla.
Konke lokhu kuholela esidingweni sokubeka amaphedi ebangeni elincane ukusuka kudiski. I-self-advance mechanism iyasebenza, futhi izindawo ezingaphezulu zamaphedi kanye nediski ezihlanganayo kufanele zibe flat ngokuphelele.
Ngemva kokushintsha amaphedi okokuqala, zonke izimo zokusebenza okujwayelekile zizophulwa:
- lapho ukhipha izingxenye ezindala futhi ufaka izingxenye ezintsha, ama-pistons amasilinda asebenzayo acwiliswe ku-caliper ngangokunokwenzeka, ngaphandle kwalokho, ngenxa yomehluko wobukhulu bamapads, ukufakwa akunakwenzeka, amaphedi amasha aphakama ngegebe elingavamile. ;
- ama-pads amadala afakwa kuma-discs, ngenxa yalokho okwavela impumuzo kuzo zonke izindawo, kodwa ukucindezelwa kwawo kanye ne-protrusions kuhambisana nendawo yokukhwelana, lokhu akuzange kube namphumela emsebenzini;
- izingxenye ezintsha kuzodingeka zixhumane nediski egugile isikhathi esithile, ngaphambi kokungena, hhayi nge-surface yonke, kodwa ngama-protrusions kuphela;
- noma ngabe ama-flat discs amasha afakiwe, ukuhlangana okuhle kwezindawo ezingaphezulu ngeke kufike ngokushesha, ukusebenza kahle kwe-braking kuzokwehla, okusho ukuthi ukuhamba kwe-pedal kuzokwanda.
Konke lokhu kuzoholela emiphumeleni emibili engathandeki. Ngemuva kokucindezela kokuqala, i-pedal izohluleka, futhi ngeke kube khona ukwehla. I-stroke ye-cylinder rod izosetshenziselwa ukuhambisa amaphedi kuma-discs, ukuchofoza okuningana kungase kudingeke ngenxa yesilinganiso esikhulu esinemibandela segiya le-drive.
Ngokuzayo, i-pedal izoba mnene kunokuvamile, futhi amabhuleki azoba ne-viscous encane ngenxa yokuxhumana okungaphelele kwama-pads nama-disc.
Ngaphezu kwalokho, amanye amaphedi anempahla enjalo ukuthi ukuze afake imodi yokusebenza, adinga ukufudumala kahle futhi athole izimfanelo ezidingekayo ze-lining material, okuzokwandisa i-coefficient ye-friction kuya kubalwa, okungukuthi, okujwayelekile.
Ungaxazulula kanjani inkinga
Ngemuva kokushintshwa, imithetho emibili elula kufanele igcinwe ukuze kuqinisekiswe ukuphepha.
- Ngaphandle kokulinda imoto ukuthi iqale ukuhamba, emva kwalokho izothola amandla e-kinetic futhi idinga ukuma phambi kwesithiyo, kuyadingeka ukucindezela i-pedal izikhathi eziningana kuze kube yilapho izuza ubulukhuni obufunayo nesivinini esincane ngaphambi kokuba ihambe.
- Ngemuva kokushintshwa, kuyadingeka ukulungisa izinga loketshezi olusebenzayo ku-master cylinder reservoir. Ngenxa yoshintsho endaweni yama-pistons, ingxenye yawo ingalahleka. Kuze kube yilapho kungena umoya ohlelweni, lapho ukupompa imigqa yomoya kuyadingeka.
Lokhu kuzoba ukuphela komsebenzi, kodwa ukusebenza kahle kwamabhuleki kusengenzeka ukuthi kubuyiselwe ngokushesha.
Okufanele ukwenze uma imoto ibhuleka kabi ngemva kokushintsha amaphedi
Ezimweni eziningi, imoto izophuka kangcono njengoba ama-pads ehlikihla kuma-disc. Lena inqubo yemvelo, akukho okungaphezu kwenkathi ethile yokuqapha edingekayo.
Imoto isazoma ngokuzethemba, kodwa umzamo kuma-pedals uzokhula kulokhu. Kungase kuthathe amashumi amakhilomitha ukubuyisela ngokugcwele ukusebenza okuvamile.
Kodwa kwenzeka ukuthi umphumela we-braking obuthakathaka awuhambi, futhi i-pedal ihlala ithambile futhi idinga ukuhamba nomzamo omkhulu.
Lokhu kungase kube ngenxa yezici zempahla yolwelwesi lwezingxenye ezintsha. Umkhiqizi ngamunye unendlela yakhe yokuthuthukisa:
- amaphedi aqine kakhulu aguga kancane, kodwa aphuka kabi futhi adle ngokushesha i-disc;
- ukuthambisa ngokweqile kunikeza i-viscosity enhle yamabhuleki, kodwa futhi nokuguga okusheshayo kwamaphedi;
- ezinye izingxenye zijwayelene kakhulu nesitayela sokushayela sezemidlalo futhi zidinga ukufudumala ukuze kwandiswe i-coefficient of friction;
- imikhiqizo eshibhile yezakhamuzi, ngokuphambene nalokho, ishisa ngokushesha futhi iqale ukwehlisa ijubane kabi;
- ngokusho kokwakheka kwezinto ezisetshenziswayo, wonke ama-pads ahlukile, insimbi, ithusi, i-carbon fiber, i-ceramics kanye nezinhlobonhlobo zezinto eziphilayo nezinye izinto ezihlanganisayo zisetshenziswa, ngenxa yalokho, kungase kubonakale kumshayeli ukuthi imithetho yokufaka esikhundleni yephuliwe, akunjalo ngaso sonke isikhathi.
Okokugcina, kungenzeka ukwenza isiphetho mayelana nokusebenza kuphela ngemva kokugijima okuthile. Uma imiphumela engathandeki ingahambi futhi ingashintshi, kuyadingeka ukuhlola isimo sesistimu ye-brake, kungenzeka ukuthi uguqule ama-pads abe ngcono futhi.
Kuyasiza nokushintsha ama-discs uma amadala eguge kabi, nakuba engekho ubukhulu obukhulu. Kodwa esimweni sokusebenza kabi kwamabhuleki, kufanele kuthathwe izinyathelo ngokushesha, lokhu kuyinkinga yezokuphepha.
