1.Material Composition & Manufacturing txheej txheem
Qhov no yog qhov tseem ceeb tshaj plaws.
1. Khoom siv:
- Cam khwb cia hlau (Grey Iron):Tus qauv rau ntau lub tsheb. Zoo sib npaug ntawm kev ua tau zoo, hnav tsis kam, thiab tus nqi. Cov alloy tshwj xeeb (carbon, silicon, chromium cov ntsiab lus) cuam tshuam lub zog, thermal stability, thiab hnav.
- Cov pa roj carbon-Ceramic Composite:Kev ua haujlwm siab heev. Exceptional tshav kub kuj (tsawg kawg ploj), lub neej ntev, thiab lub teeb yuag. kim heev thiab siv rau siab -kawg kis las/supercars.
- Bimetallic/Semi-Hloov:Ib tug cam khwb cia hlau kev sib txhuam nplhaib bonded rau ib tug txhuas los yog stainless hlau hub. Txo qhov hnyav thiab txhim kho cov cua txias tab sis yog qhov nyuaj rau kev tsim khoom.
2. Casting Quality:Kev ywj pheej los ntawm impurities (slag, huab cua hnab tshos) thiab kev ntxhov siab sab hauv ua kom lub zog zoo ib yam thiab tiv thaiv kev sib tsoo lossis tawg.
3. Kev kho cua sov & Machining:Cov txheej txheem zoo liannealing(kom txo tau kev ntxhov siab) thiabprecision machiningrau du, parallel nto yog qhov tseem ceeb. High- cov discs zoo feem ntau ua rau cov cua sov tshwj xeeb kom ruaj khov ntawm cov hlau.
2. Cov khoom cua sov
Braking hloov lub zog kinetic rau hauv qhov kub heev.
1. Thaum tshav kub kub muaj peev xwm & Dissipation:Lub disc yuav tsum nqus thiab dissipate tshav kub sai kom tsis txhob:
- Nres Fade:Poob lub zog nres thaum lub disc thiab cov ntaub qhwv overheat.
- Warping:Tsis sib xws cua sov thiab cua txias tuaj yeem ua rau qhov sib txawv ntawm thickness (runout), ua rau pedal pulsation.
- Kev tawg:Thermal kev nyuaj siab los ntawm ceev, huab cua hloov pauv.
2. Vented Designs:Feem ntau niaj hnub rotors pem hauv ntej yog vented nrog cov fins sab hauv los kos cov cua sov kom deb ntawm qhov chaw sib txhuam.
3. Directional Vanes:High- discs kev ua tau zoo muaj qhov nkhaus lossis "ncej" vanes uas ua haujlwm zoo li lub kiv cua centrifugal, ua rau muaj kev txhim kho huab cua thiab cua txias.
3. Mechanical & Structure Design
1. Loj (inch & Thickness):Txoj kab uas hla loj dua tsub kom torque (tsawg zog) thiab txhim kho qhov txias vim qhov chaw ntau dua. Cov tuab txaus xav tau rau lub peev xwm kub thiab ua kom tau raws li qhov kev txwv tsawg kawg nkaus.
2. Fin Design:Raws li tau hais, cov duab thiab kev taw qhia ntawm cov cua txias sab hauv yog qhov tseem ceeb rau kev ua haujlwm rotors.
3. Hub Design:Kev sib txuas rau lub log hub yuav tsum yog qhov tseeb kom txo qis kev khiav tawm thiab kev co.
4. Qhov & Qhov Nta:
- Slotted Discs:So tawm cov ntaub qhwv ntsej muag thiab tawm, txhim kho tom hauv cov dej ntub dej, tab sis ua kom cov ntaub qhwv npog.
- Drilled Discs:Feem ntau rau kev zoo nkauj thiab qee qhov kev tshem tawm dej; lawv tuaj yeem ua rau tawg nyob rau hauv kev siv huab cua. Qhov zoo tshaj plaws rau siab -kev siv txoj kev.
- Ua ke:Slotted thiab drilled muab kev sib haum xeeb tab sis feem ntau yog rau siab -kev ua tau zoo ntawm txoj kev.
4. Cov yam ntxwv saum npoo & txheej txheej
1. Initial Surface Finish:Kev ua tiav zoo ib yam ua kom cov ntaub pua chaw zoo - hauv cov pawm nres.
2. Txheej & Kev Kho Mob:
- Geomet® Txheej (los yog zoo sib xws):Kev tiv thaiv corrosion-cov tshuaj tiv thaiv tau siv rau qhov tsis yog- qhov chaw sib txhuam (lub kaus mom, cov npoo) txhawm rau tiv thaiv xeb thiab ua kom zoo dua qub.
- Zinc, Nickel, lossis Cadmium Plating:Ua haujlwm zoo sib xws los tiv thaiv- lub hom phiaj corrosion.
- Nitriding / Carbonizing:Kev kho deg hardening kom hnav tsis kam thiab txo cov qhab nia.
5. Ua raws li Cov Qauv & Kev Ntsuas
- OEM vs. Tom qab kev muag khoom:OEM discs raug tsim los ua kom tau raws li lub tuam txhab tsim tsheb cov qauv tshwj xeeb rau lub suab nrov, kev vibration, hnyav (NVH), thiab kev ua haujlwm.
- Cov ntawv pov thawj:Reputable manufacturers ua raws li cov qauv zoo thoob ntiaj teb (xws li ISO, JIS, DIN).
- Kev kuaj:Cov rotors zoo tau raug kuaj nruj rau qhov sib npaug, thermal cycling, qhov tseeb qhov tseeb, thiab cov khoom sib xws.
Cov cim qhia tsis zoo ntawm Nres Nres Discs
- Premature Warping:Ua rau nres pedal pulsation.
- Hnav ntau dhau los yog tsis sib xws:Kev nrawm nrawm los yog sib sib zog nqus.
- High Susceptibility rau Rust:Tshwj xeeb tshaj yog nyob rau ntawm kev sib txhuam nto tom qab lub sij hawm luv luv ntawm inactivity.
- Kev tawg:Nyob rau hauv ib txwm muaj lossis nruab nrab kev ntxhov siab.
- Suab nrov (squealing/groaning):Feem ntau yog vim qhov tsis zoo ntawm qhov chaw tiav lossis cov khoom tsis sib xws.
- Incorrect Dimensions los yog Imbalance:Ua rau kev vibration lossis tsis tsim nyog.
