Enziwa Kanjani Ama-Brake Rotors?

Uma ungumnikazi wemoto entsha futhi uzibuza ukuthi ama-rotor amabhuleki enziwa kanjani, funda ukuze ufunde kabanzi mayelana nenqubo.Lapha, sizoxoxa ngokuthi ama-brake rotor enziwa kanjani ngezinto ezithandwa kakhulu, i-aluminium alloy ne-ceramic.Sizophinde sihlole ukuthi kungani i-ceramic iyimpahla engcono kakhulu yama-rotor amabhuleki.Okokugcina, sizoxoxa ngokuthi zenzelwe kanjani ukusebenzisana ukuze zenze imoto enamandla kakhulu, ephephe kakhudlwana.

Ingxube ye-aluminium

Ucwaningo olushicilelwe ku-Bull.UMater.Isayensi.ibonisa ukuthi izindleko ze-aluminium alloy brake rotors zingaphansi kuka-2.5% kune-AA6063 ehlanzekile.Lokhu kunciphisa isisindo kuphinde kuzuzise amasistimu amasondo angaphakathi.Inqubo iphumelela ekunciphiseni isisindo sonke se-rotor ngo-20%.Izinzuzo zibalulekile.Ingxubevange ilula ngokwanele ukunciphisa isisindo sonke ngo-20%.Ngaphezu kwalokho, yehlisa isisindo sisonke ngo-30%.

Enye inzuzo ye-aluminium braking rotor ukuthi ayisindi, ahlakaza ukushisa ngokushesha, futhi ancibilike ezingeni lokushisa eliphansi kunezinye izinto eziningi.Le nto engasindi ifaneleka kakhulu izithuthuthu, njengoba zinesisindo esingaphansi kakhulu kunezimoto ezinzima.Ngaphezu kwalokho, amabhuleki e-aluminium alula kumabhuleki.Ngaphezu kwe-aluminium, i-carbon brake rotors iyinsimbi equkethe ikhabhoni.Okuqukethwe kwe-carbon metallic kuvimbela i-rotor ukuthi ingaqhekeki uma ingaphansi kwengcindezi ephezulu futhi kunciphisa umsindo wamabhuleki nokudlidliza.Nokho, lezi rotor zibiza kakhulu kune-ayoni.

I-alumina-coated aluminium brake rotor iyindlela esebenzayo ezimotweni zentengiso.Zingenziwa ngokwezifiso ukuze zivumelane nezidingo zesigaba ngasinye se-rotor.Ngaphezu kwalokhu, ama-rotor e-aluminium alloy brake mancane amathuba okuthi aklwebhe.Zihlala isikhathi eside.I-Aluminium alloy brake rotors ingenziwa ibukeke njenge-carbon brake rotor.

Indlela ekhethwayo yokukhiqiza i-aluminium alloy brake rotors ihlanganisa ukwenza ucezu lomsebenzi oluvela ku-billet.I-rotor billet ilungiselelwe ukuthi ibe nezindawo ezifiselekayo, ezifana nokumelana nezinga lokushisa eliphezulu nokumelana nokugqoka okuphezulu.I-prototype aluminium alloy brake rotor yakhiqizwa futhi inobubanzi obungaphandle obungu-12.2 amayintshi nogqinsi lwamayintshi angu-0.625.Yayinesisindo esingamakhilogremu angu-1.75 ngemva komshini.

Isinyathelo sokuqala sokukhiqiza i-aluminium alloy brake rotor ukudala isikhunta.Lesi sikhunta senziwe kusetshenziswa isigayo se-CNC.Phakathi nale nqubo, ishidi lensimbi elinezilinganiso eziqondile ze-rotor lisikwa kusetshenziswa isikhunta.Phakathi nenqubo, i-blade yokusika ifakwe ku-workpiece ekujuleni okufiselekayo.Ukufaka nokukhipha i-blade ngokuphindaphindiwe kungakhiqiza ama-rotor ngokujula ngokuqhubekayo.

I-aluminium alloy kanye ne-ceramic

Inqubo yokukhiqiza i-aluminium alloy kanye ne-ceramic brake rotors ihlanganisa ukungeza izingxenye ezisezingeni elisebenzayo kumpushana osekelwe ku-alumina.I-rotor ewumphumela inobukhulu obufanayo, kodwa ilula kakhulu.Ukukhiqiza okungeziwe kunganciphisa isisindo se-rotor ngamakhilogremu angu-20, okuwukuthuthuka okukhulu kunezindlela zendabuko.Ngaphezu kwalokho, ama-rotor e-ceramic ahlala isikhathi eside kune-aluminium alloy rotors.

Nakuba ama-rotor asekelwe ensimbi kuyizinhlobo ezivame kakhulu, angenziwa futhi ngezinye izinto.Izinzuzo eziningana zihlotshaniswa ne-high-tech brake rotors: zilula futhi zihlala isikhathi eside, futhi zingakwazi ukumelana namazinga okushisa aphezulu.Nokho, uma amabhuleki akho ejwayele ukuqhekeka, kungaba yingozi.Ama-rotor e-aluminium alloy brake ahlala isikhathi eside kunama-rotor asekelwe ku-iron, futhi ayabiza kakhulu.

Inqubo yokukhiqiza i-aluminium alloy disc rotor iyafana naleyo yokukhiqiza i-ceramic brake rotor.Ingxubevange yakhiwa ngokucindezela kanye nokukhama-casting aqukethe ama-alloys, njenge-AA356.Ingxenye eyinhlanganisela ye-rotor yenziwa ngomshini ngendlela oyifunayo.Ngemuva kwalokho, iphiliswa ukushisa ukuze kuzuzwe izici ezifiselekayo zendawo.Kuyindlela ephumelelayo evumela ukongiwa kwamandla.

Inqubo yokukhiqiza i-aluminium alloy noma i-ceramic brake rotor isebenzisa isithando somlilo esikhethekile.Ama-rotor abe esefakwa endaweni engenawo umoya-mpilo futhi embozwe ungqimba oluncane lwe-silicon.Kule nqubo, i-nitrogen iphonswa kuhhavini ukuze isuse umoya, ngaleyo ndlela iguqule i-silicon ibe uketshezi.Ngaphandle kokudlulisa ukushisa, i-rotor imelana nokugqwala nokugqwala.

Ngokungeziwe ku-dynamics yokushayela ethuthukisiwe, i-chassis engasindi nayo yehlisa ukusetshenziswa kukaphethiloli.Ngokusebenzisa i-bi-material brake disc, umenzi angonga ikhilogremu eyodwa kuya kwamabili ngebhuleki ngalinye.Kodwa-ke, isibalo esinembile sizoncika kumodeli yemoto kanye nenani lempahla edingekayo.Umqondo "Cobadisk" ungase usetshenziselwe izimoto kusukela A-to-S ingxenye.Ukwakhiwa kwayo okungasindi kuyenza ibe yisinqumo esifiselekayo kubashayeli bazo zonke izabelomali.

U-Santa brake ungumkhiqizi ochwepheshile wamabhuleki namabhuleki e-China onolwazi olungaphezu kweminyaka eyi-15.Njengefekthri yebhuleki ne-brake pads kanye nomphakeli, simboza imikhiqizo emikhulu yokuhlela yama-rotor e-auto brake nama-brake pads amanani ancintisanayo kanye nempahla yamabhuleki ka-Santa emazweni angaphezu kuka-30+ anamakhasimende ajabule angaphezu kuka-80+ emhlabeni.Siyakwamukela ekufinyeleleni imininingwane eyengeziwe!
