Kufanele ashise kangakanani ama-brake discs emotweni?
Okuqukethwe
Ama-brake discs aklanyelwe ukushisisa. Lena ukuphela kwendlela yokuguqula amandla e-kinetic emoto esheshayo ibe ukushisa bese iwachitha emkhathini. Kodwa lokhu kufanele kwenzeke ngokuqinile ngomyalo womshayeli. Ukushisa kwamabhuleki kuzo zonke ezinye izimo kubonisa ukuba khona kokungasebenzi kahle, kanye nezinketho eziphuthumayo, okungukuthi, ukushisa ngokweqile.
Izici zesistimu yamabhuleki emoto
Umsebenzi wamabhuleki ukumisa imoto ngokushesha nangokuphepha ngangokunokwenzeka. Indlela elula yokwenza lokhu ngosizo lwamandla okushayisana, okwenzeka ezindleleni zamabhuleki.
Amabhuleki atholakala ezimotweni zesimanje esondweni ngalinye ukuze akwazi ukubamba ngokugcwele amathayi emgwaqeni.
Umsebenzi usebenzisa:
- ama-brake discs noma izigubhu, izingxenye zensimbi ezihlobene nama-wheel hubs;
- ama-brake pads, ahlanganisa isisekelo kanye nama-linings enziwe ngezinto ezine-coefficient ephezulu yokungqubuzana ngokumelene ne-cast iron noma insimbi futhi ngesikhathi esifanayo imelana nokushisa okuphezulu ngokuguga okuncane kokubili kwamaphedi ngokwawo kanye nama-disc (izigubhu);
- i-brake drive, i-mechanical, i-hydraulic kanye nemishini kagesi edlulisa amandla ukusuka ezilawulweni zomshayeli kuya ezindleleni zamabhuleki.
Kunezinhlobo eziningana zama-brake systems, indima ebalulekile ekushiseni kwama-disc idlalwa yisevisi kanye namabhuleki okupaka.
Zombili zisebenza ngendlela efanayo - umshayeli ngedrayivu udala amandla emishini kuma-brake pads, acindezelwa kuma-disc noma izigubhu. Kukhona i-friction force eqondiswe ngokumelene ne-inertia yemoto, amandla e-kinetic ayancipha, ijubane liyehla.
Ingabe kufanele kushise ama-brake discs nezigubhu?
Uma sibala amandla okubhuleka, futhi lokhu kungamandla akhululwa ngendlela yokushisa ngesikhathi sokubhuleka ngesikhathi seyunithi, khona-ke izodlula amandla enjini izikhathi eziningi.
Kulula kakhulu ukucabanga ukuthi injini ishisa kanjani, kuhlanganise namandla athathwe namagesi e-exhaust futhi asetshenziswe emsebenzini owusizo wokuhambisa imoto nomthwalo.
Kungenzeka ukwaba inani elikhulu kangaka lamandla kuphela ngokwenyuka okukhulu kwezinga lokushisa. Kuyaziwa kusukela ku-physics ukuthi ubuningi be-flux yamandla bulingana nomehluko wezinga lokushisa, okungukuthi, umehluko phakathi kwe-heater nesiqandisi. Lapho amandla engenaso isikhathi sokungena esiqandisini, kulokhu kungumoya wasemkhathini, izinga lokushisa liyakhuphuka.
I-disk ingakhanya ebumnyameni, okungukuthi, ithole amadigri angamakhulu amaningana. Ngokwemvelo, ngeke sibe nesikhathi sokuphola phakathi kwe-braking, kuzoshisa lonke uhambo.
Izizathu ezishisayo
Kunomehluko omkhulu kakhulu phakathi kokushisisa nokushisa ngokweqile. Ukushisa kuyinto evamile, okungukuthi, ibalwa futhi ihlolwe ngabathuthukisi bezimoto, futhi ukushisa ngokweqile kuyisimo esiphuthumayo.
Kukhona okungahambanga kahle, izinga lokushisa likhuphuke kakhulu. Endabeni yamabhuleki, lokhu kuyingozi kakhulu, ngoba izingxenye ezishisiwe azikwazi ukusebenza ngokujwayelekile, zilahlekelwa amandla, i-geometry kanye nensiza ngokushesha okukhulu.
Imiphumela yokushayela kwi-handbrake
Into elula cishe bonke abashayeli be-novice abahlangabezana nayo ukukhohlwa ukususa ibhuleki yokupaka ekuqaleni kokunyakaza.
Sekuyisikhathi eside onjiniyela bezabalaza ngempumelelo nalokhu kukhohlwa. Bekunama-alamu alula nemisindo aqanjwayo uma uzama ukusuka efakwe ama-pads aqinile, kanjalo nama-handbrake azishintshayo ashaywa ngogesi uma imoto ima isuka.
Kodwa uma usashayela amaphedi acindezelwe, amandla adlulisiwe abalulekile azoshisa izigubhu kangangokuthi ama-pad linings azosha, insimbi izokonakala, futhi amasilinda amanzi avuze.
Lokhu kuvame ukuqashelwa kuphela lapho amathayi kumadiski eqala ukubhema. Kuzodinga ukulungiswa okubanzi nokubizayo.
I-caliper piston enamathele
Ezindleleni ze-disc, awekho amadivaysi ahlukene okukhipha ama-pistons kuma-pads. Ukucindezela ohlelweni lwe-hydraulic kuyasuswa, amandla okubamba abe yi-zero, futhi amandla okuxubana alingana nomkhiqizo wokucindezela ku-block kanye ne-coefficient of friction. Okungukuthi, "zero" akunandaba ukuthi iyiphi inombolo - kuyoba "zero".
Kodwa akusebenzi njalo. Ibhulokhi kufanele ihoxiswe ngengxenye yemilimitha, okungenani ngenxa yokunwebeka kwe-cuff yokuvala. Kodwa uma ukugqwala kwenzeke phakathi kwe-piston nesilinda se-caliper, futhi i-piston iboshwe, amaphedi azohlala ecindezelwe ngamandla angewona aziro.
Ukukhululwa kwamandla nokushisa okungalawuleki kuzoqala. Izophela kuphela ngemva kokuba ukushuba okuthile kwesendlalelo kususiwe ekumbondeleni ngenxa yokushisa nokulahlekelwa izakhiwo. Ngesikhathi esifanayo, idiski nayo izoshisa kakhulu.
Umoya ohlelweni lokubhuleka
Akuvamile, kodwa umphumela ubonakale lapho amaphedi ecindezela ngokuzenzakalelayo kuma-disc ngenxa yokumpompa okungalungile kwedrayivu evela emoyeni.
Iyanda ekushiseni futhi iqala ukucindezela amaphedi ngokumelene namadiski ngokusebenzisa amasilinda. Kodwa noma kunjalo, ngaphambi kokushisa ngokweqile, umshayeli uzoqaphela ukuthi imoto empeleni ayinciphisi.
Ukugqoka i-brake disc
Uma egqokwe, ama-discs alahlekelwa isimo sawo sejometri esifanelekile. Kuvela ukukhululeka okubonakalayo kubo, amaphedi azama ukungena kuwo.
Konke lokhu kuholela ekuxhumaneni okungalindelekile phakathi kwezindawo zama-disc kanye ne-linings, futhi noma yikuphi othintana nabo kuzosho ukushisa ngokweqile nayo yonke imiphumela elandelayo.
Ukushintshwa okungalungile kwama-brake pads
Uma ubuchwepheshe bokushintsha i-pad buphulwa, kukho konke ukulula kwabo esimweni se-disc brake, ama-pads angase ajame ku-caliper.
Ukungqubuzana okubangelwayo kuzoshisa kakhulu i-disc kanye ne-caliper guide vane, okuzokwandisa isimo kuphela. Ivamise ukuphetha ngokuthi umshayeli abone imisindo ephuma ngaphandle kanye nokwehla kakhulu kokusebenza kwamabhuleki.
Ungawasusa kanjani ama-discs okushisa
Kunemithetho elula yokonga amabhuleki ekushiseni ngokweqile:
- sebenzisa amabhuleki ezimeni eziphuthumayo kuphela nalapho ume okokugcina, kuzo zonke ezinye izimo, ugudle ugu ngaphansi kokuphonswa kwenjini okuhle noma okungekuhle;
- ungasebenzisi amabhuleki ekwehleni okude ezintabeni, injini kuphela noma ibhuleki lentaba, uhlelo lwenkonzo cishe luzosinda endaweni ephansi kakhulu yokwehla kokuqala okukhulu, ukuze uqiniseke ngalokhu, kwanele ukubala amandla amandla imoto enawo esiqongweni sentaba;
- gcina izindlela zamabhuleki zisesimweni esiphelele, uqinisekisa ukuthi akukho ukugqwala kwama-hydraulics neziqondiso ngokushintshwa ngakunye kwamapads, kusetshenziswa okokugcoba okukhethekile kanye nemephu yesicelo sayo;
- buyisela ngesikhathi esifanele ama-disc ngokuguga ngokweqile, ngaphandle kokulinda ukubonakala kwawo okuphelele.
Amadiski ashiswe ngokweqile kufanele ashintshwe. Baye balahlekelwa amandla, i-coefficient yabo yokungqubuzana ishintshile ngisho nangamapayipi amasha, futhi okubaluleke kakhulu, ayilingani endaweni, okuzoholela kuma-jerks nokushisa okusha.
Imiphumela yokusebenza okungalungile kwesistimu yamabhuleki
Amadiski ashiswe ngokweqile ajwayele ukushintshwa lapho kuzwakala i-thump ku-pedal yebhuleki kuya ekugqithweni kwesondo. Uma lesi sinyathelo esiyisibopho singanakwa, khona-ke ukubhujiswa kwe-disc ngesikhathi sokubopha kungenzeka.
Lokhu kuvame ukuthi kugcine ngokuba ne-catastrophic wheel jam bese imoto ishiya umzila ngendlela engaqondakali. Ngomfudlana ominyene wesivinini esikhulu, ingozi enkulu ayinakugwenywa, cishe nezisulu.
Ku-MOT ngayinye, ama-disc ahlolwa ngokucophelela. Akufanele kube nemibala e-tint evela ekushiseni ngokweqile, ukukhululeka okuphawulekayo, ukugoba noma inethiwekhi yokuqhekeka.
Ama-disc ahlala eshintshwa kanye nama-pads, futhi uma kwenzeka ukugqoka okungalingani - futhi nokubuyekezwa kwama-calipers.
