Lirota tsa Brake li Etsoa Joang?

Haeba u mong'a koloi e ncha 'me u ipotsa hore na li-rotor tsa brake li etsoa joang, joale bala ho ithuta ho eketsehileng ka mokhoa ona.Mona, re tla tšohla hore na li-rotor tsa brake li entsoe joang ka thepa e tsebahalang haholo, alloy ea aluminium le ceramic.Re tla boela re hlahlobe hore na ke hobane'ng ha ceramic e le thepa e ntle ka ho fetisisa bakeng sa li-rotor tsa brake.Qetellong, re tla tšohla hore na li etselitsoe ho sebetsa 'moho joang ho etsa koloi e matla haholoanyane, e sireletsehileng haholoanyane.

Motsoako oa aluminium

Phuputso e phatlalalitsoeng ho Bull.Mater.Sci.e bontša hore litšenyehelo tsa aluminium alloy brake rotors ke 2.5% ka tlase ho AA6063 e hloekileng.Phokotso ena ea boima e boetse e tsoela molemo tsamaisong ea mabili a ka hare.Mokhoa ona o atleha ho fokotsa boima ba rotor ka 20%.Melemo ke ea bohlokoa.Alloy e bobebe ho lekana ho fokotsa boima ba 'mele ka 20%.Ho feta moo, e fokotsa boima ba kakaretso ka 30%.

Molemo o mong oa li-rotor tsa braking tsa aluminium ke hore li bobebe, li tlosa mocheso ka potlako, 'me li qhibiliha ka mocheso o tlase ho feta lisebelisoa tse ling tse ngata.Thepa ena e bobebe e loketse haholo lithuthuthu, kaha boima ba tsona bo tlase haholo ho feta likoloi tse boima.Ho feta moo, li-rotor tsa aluminium li bonolo holima mariki.Ho phaella ho aluminium, li-rotor tsa carbon brake ke tšepe e nang le carbon.Lintho tsa tšepe tsa carbon li thibela rotor hore e se ke ea robeha ha e le tlas'a khatello e matla 'me e fokotsa lerata le ho thothomela.Leha ho le joalo, li-rotor tsena li theko e boima ho feta tšepe.

Alumina-coated aluminium brake rotor ke khetho e sebetsang bakeng sa likoloi tsa khoebo.Li ka etsoa ka tloaelo ho lumellana le litlhoko tsa karolo ka 'ngoe ea rotor.Ho phaella ho sena, li-rotor tsa aluminium alloy brake ha li na monyetla oa ho ngolisoa.Li boetse li tšoarella ho feta.Aluminium alloy brake rotor e ka etsoa hore e shebahale joalo ka lirotara tsa brake tsa carbon.

Mokhoa o ratoang oa ho etsa li-rotor tsa aluminium alloy brake o kenyelletsa ho lokisa sesebelisoa ho tsoa ho billet.The rotor billet e lokiselitsoe hore e be le thepa e lakatsehang, e kang ho hanyetsa mocheso o phahameng le ho hanyetsa ho apara holimo.Ho ile ha etsoa prototype aluminium alloy brake rotor 'me e na le bophara ba lisenthimithara tse 12.2 le bophara ba lisenthimithara tse 0.625.E ne e le boima ba lik'hilograma tse 1,75 ka mor'a ho sebetsa ka mochine.

Mohato oa pele oa ho etsa aluminium alloy brake rotor ke ho theha hlobo.Mofuta ona o entsoe ka leloala la CNC.Nakong ea ts'ebetso ena, lesela la tšepe le nang le litekanyo tse nepahetseng tsa rotor le khaoloa ho sebelisoa hlobo.Nakong ea ts'ebetso, lehare la ho itšeha le kenngoa ka har'a workpiece ho ea botebo bo lakatsehang.Ho kenya le ho ntša lehare khafetsa ho ka hlahisa li-rotor tse nang le botebo bo tsoelang pele.

Aluminium alloy le ceramic

Mokhoa oa ho etsa aluminium alloy le ceramic brake rotor o kenyelletsa ho kenyelletsa likarolo tse sebetsang hantle ho phofo e thehiloeng ho alumina.Rotor e hlahisoang e na le botenya bo tšoanang, empa e bobebe haholoanyane.Ho etsa lintho tse eketsehileng ho ka fokotsa boima ba rotor ka liponto tse 20, e leng ntlafatso e kholo ho feta mekhoa ea setso.Ho phaella moo, li-rotor tsa ceramic li tšoarella ho feta li-rotor tsa aluminium alloy.

Le hoja li-rotor tse entsoeng ka tšepe ke tsona mefuta e tloaelehileng ka ho fetisisa, li ka boela tsa etsoa ka lisebelisoa tse ling.Melemo e 'maloa e amahanngoa le li-rotor tse phahameng tsa theknoloji: li bobebe ebile lia tšoarella,' me li khona ho mamella mocheso o phahameng.Leha ho le joalo, haeba mariki a hao a tloaetse ho robeha, ho ka ba kotsi.Aluminium alloy brake rotor e tšoarella ho feta li-rotor tse thehiloeng ka tšepe, hape li theko e boima haholo.

Mokhoa oa ho etsa aluminium alloy disc rotor o tšoana le oa ho etsa rotor ea brake ea ceramic.The alloy e thehoa ka ho tobetsa le ho penya-ho lahla li-alloys tse nang le aluminium, tse kang AA356.Karolo e kopantsoeng ea rotor e entsoe ka mokhoa o lakatsehang.Ka mor'a moo, e phekoloa ka mocheso ho finyella litšobotsi tse lakatsehang tsa holim'a metsi.Ke mokhoa o sebetsang hantle o lumellang ho baballa matla.

Mokhoa oa ho etsa aluminium alloy kapa ceramic brake rotor o sebelisa sebōpi se khethehileng.Joale li-rotor li kenngoa sebakeng se se nang oksijene 'me li koahetsoe ka lesela le lesesaane la silicon.Ts'ebetsong ena, naetrojene e pompeloa ka ontong ho tlosa moea, kahoo e fetola silicon hore e be metsi.Ntle le ho fetisoa ha mocheso, rotor e hanyetsana le mafome le ho senya.

Ntle le matla a matla a ho khanna, chassis e bobebe e boetse e theola tšebeliso ea mafura.Ka ho sebelisa bi-material brake disc, moetsi a ka boloka kilogram e le 'ngoe ho isa ho tse peli ka brake.Leha ho le joalo, palo e nepahetseng e tla itšetleha ka mohlala oa koloi le palo ea thepa e hlokahalang.Khopolo ea "Cobadisk" e ka sebelisoa bakeng sa likoloi tse tsoang karolong ea A-to-S.Kaho ea eona e bobebe e ba etsa khetho e lakatsehang bakeng sa bakhanni ba lichelete tsohle.
