Nres Pads: interface tseem ceeb rau kev nyab xeeb hauv tsheb

Cov nres nres yog cov kev sib txhuam tsis muaj kev sib txhuam ntawm cov khoom nres disc nres, qhov tseem ceeb rau kev hloov kho lub zog (cua sov) kom qeeb lossis nres tsheb. Lawv qhov kev ua tau zoo cuam tshuam cuam tshuam kev nyab xeeb, suab nrov, plua plav, thiab ntev. Nkag siab txog lawv cov lej, hom, thiab cov yam ntxwv yog qhov tseem ceeb rau cov engineers, technicians, thiab qhia cov neeg siv khoom.

Cov Khoom Siv Hluav Taws Xob: Ib Txoj Kev Txhiab Hniav

Cov ntaub ntawv nres nres niaj hnub no yog cov sib xyaw ua kom nruj, feem ntau suav nrog:

1. Kev sib txhuam hloov kho (30-60%): Cov ntaub ntawv tseem ceeb tsim kev sib txhuam. Piv txwv li:

Nws yog xim hlau: hlau, hlau, tooj liab (raug ua ntu).

Ceramics: silicon carbide, alumina, ceramic fibers.

Abrasives: silica, alumina, magnesium oxide (huv rotors, hloov kho kev sib txhuam).

Cov roj nplua nyeem: Graphite, molybdenum disculide (txo cov suab nrov, ruaj khov kev sib txhuam).

Kev txhawb nqa: Aramid Fibers (Kevlar), iav cov fibers, carbon fibers (lub zog, fade, fade tiv taus).

2. Cov txheej txheem sib dhos (15-25%): Thermoset cov khoom siv (feem ntau phenol) uas tuav cov matrix ua ke, kho nyob rau hauv tshav kub kub thiab siab. Lawv yuav tsum muaj kev ncaj ncees ntawm qhov kub.

3. Tumpers (10-30%): Khoom zoo li barite (barium sulfate), bacium carbonate, lossis cashew txiv ntseej plhaub derivatives. Lawv tswj tus nqi, ntom, thermal conductivity, thiab manufacturity.

4. Cov cuab yeej hloov kho (5-15%): Ntxiv rau cov kev xav tau tshwj xeeb: Vermiculite hais rau cov rwb thaiv tsev thermal, hlau sulfides rau fade tiv taus.

Loj Nres Pad Hom: Kev Ua Yeeb Yam & Cov Ntawv Thov

1. Tsis -} Asbestos Organic (Nao):

Composition: feem ntau cov organic fibers (iav, ntsuaslar, cellulose), fillers, thiab resins. COPPER -} dawb variants dominate tam sim no.

Cov yam ntxwv: Cov neeg nyob ntsiag to, qis rotor hnav, tsawg hmoov av, tus nqi nruab nrab. Keeb kwm softer, tab sis cov qauv niaj hnub muaj cov khaub thuas zoo thiab zoo ib yam rau kev tsav tsheb txhua hnub.

Qhov zoo tshaj plaws rau: Txheem cov neeg caij tsheb tsheb, lub teeb {{{0} Lub luag haujlwm thov. Cov nrov xaiv OE xaiv rau ntau cov sedans thiab SUVs. Niaj hnub nimno naos kev muaj zoo txhua - nyob ib ncig ntawm kev ua haujlwm.

2. Semi - nws yog xim hlau:

Composition: 30-65% ferrous hlau (steel, hlau wool), graphite, txhuam cov hloov kho, binders. Tooj liab tseem nyob hauv qee qhov tab sis tsis lees paub.

Cov yam ntxwv: Tshav kub ua tau zoo heev dissipation, zoo - kub ua tau zoo thiab fadeistance. Muaj peev xwm tsis muaj peev xwm nrov, plua plav, thiab ua rau ntau dua rotor hnav dua nao lossis ceramic. Feem ntau ruaj.

Qhov zoo tshaj plaws rau: cov tsheb hnyav (SUVs, tsheb thauj khoom), kev ua tau zoo cov ntawv thov (sprited txoj kev tsav tsheb), spain. Nquag o ntawm cov tsheb thauj khoom / SUVs.

3. Ceramic:

Kev sib xyaw: high - density} rensity ceramic fibers / tebchaw, tsis {{1} ferrous ovricers hloov kho, fitters, khi cov resins. Tooj - dawb.

Cov yam ntxwv: kev ua haujlwm nyob ntsiag to heev, feem ntau lub teeb {{{xim), minimal rotor hnav, ruaj khov zoo tshaj qhov kub thiab txias. Tsawg dua qhov pib "tom" dua li qee qhov semi- meters thaum txias, feem ntau raug nqi. Zoo heev fade kuj rau feem ntau txoj kev siv.

Qhov zoo tshaj plaws rau: Hwm cov tsheb caij nyoog, cov tsheb khoom kim heev, vim cov suab nrov / hmoov av), cov tsav tsheb ua ntej kev nyiam huv thiab nyob ntsiag to. Cov tseem ceeb hauv tus nqi them rov qab tom qab kev pab cuam thiab OE rau EVS / Mid- high kawg tsheb.

4. Tsawg {- nws yog xim hlau variant nrog ib feem me me (10 {}} 20%) ntawm cov mos mos (tooj liab) ntxiv rau ib qho nao puag. Muaj kev sib npaug ntawm kev ua kom zoo dua thiab ua kom kub siab dua li cov qauv nao nrog cov suab tsawg dua / hmoov av dua li cov xim hlau tag nrho.

5. Kev sib tw / kev ua tau zoo: Cov qauv tshwj xeeb (feem ntau sintered xim av, carbon {1} {{1 {{{{2} Weè Works {. Ua ntej tshaj tawm kev sib txhuam coefficient ntawm qhov kub siab heev, fade tsis kam, thiab kev hloov kho. Kev ua suab nrov, plua plav, rotor hnav, thiab kev ua si txias. Tsis haum rau kev siv txoj kev ib txwm siv.

Kev Ntsuas Cov Ntsiab

Kev sib txhuam coefficient (μ): ntsuas siv fais fab. Ntau Dua {{{{= sheetter nres deb, tab sis yuav tsum tau ua tib zoo ntsuas. Yuav tsum ruaj khov thoob plaws.

Fade Kuj: muaj peev xwm tswj kev sib txhuam thaum kub tau nce siab heev tshwm sim thaum lub sij hawm ua dua qhuav. Tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm tsav tsheb.

Hnav tus nqi: Yuav ua li cas nrawm nrawm rau. Cuam tshuam rau kev ua neej ntev thiab tus nqi ntawm cov tswv cuab. Txhoj puab heev pads hnav sai dua.

Rotor coj: qee cov ntaub qhwv ua qauv nyuaj rau lub cev nres tsheb dua lwm tus.

Suab nrov (Squeal / Txiav Txim): tshwm sim los ntawm kev co ntawm ncoo / rotor interface. Dampening shims, chamfers, slots, thiab kev sib txhuam kev txhuam khoom tshwj xeeb.

Ntau tiam: tus nqi thiab hom hmoov av tso tawm thaum lub sijhawm braking. Ceramics feem ntau ua qhov tsawg tshaj plaws (thiab ntais - xim.

Kev tom mob txias: kev ua tau ua haujlwm thaum thawj peb nres thaum cov ntaub qhwv / Rotors txias. Tseem ceeb heev rau kev nyab xeeb hauv txhua yam xwm txheej.

Pedal xav / hloov: Tus tsav tsheb lub tswv yim nrhiav kev tawm tswv yim thiab muaj peev xwm los txhawb kev tswj hwm braking.

Xaiv lub ncoo kom yog

Xaiv qhov tseeb ncoo cuam tshuam ntau yam:

1. Tsheb thov: Match ncoo ntaus rau lub tsheb yuag, Powertrain (Ev vs. Ice), thiab raug, kev ua haujlwm, kev ua tau). Sab laj rau oe specifications lossis cov npe rov qab tau tom qab cov lus qhia.

2. Tsav tsheb style: Cov tsav tsheb hnyav yuav tsum tau them dua siab dua; cov neeg sawv cev ua ntej muaj cov hmoov av ntsiag to thiab cov hmoov av qis.

3. Ib puag ncig cov xwm txheej: ntub dej / huab cua huab cua nce kev pheej hmoo - padsting "kev ua yeeb yam thiab corrosion inibitors muaj txiaj ntsig.

4. Nyiaj txiag yog tus nqi them, semi- met} me ntsis kev lag luam (txawm tias siab {}}} kev ua haujlwm naos muaj nyob). Xav txog kev ua haujlwm ntev thiab tus nqi pib.

5. Cov ntsiab lus tseem ceeb: Kev ua suab nrov, plua plav, rotor, rotor lub neej, pib tom, thiab siab {1}-}} kub ua tau zoo.

6. Ua kom zoo: lo nrog cov npe ntawm cov neeg muab khoom siv lossis cov cim npe (piv txwv li cov khoom lag luam Tswjhwm zoo nyob rau hauv kev sib txhuam cov khoom lag luam yog qhov tseem ceeb rau kev nyab xeeb thiab kev ua tau zoo sib xws.

Txij Nkawm & Kev Nyab Xeeb

Cov nres nres tau hnav cov khoom. Kev kuaj xyuas tsis tu ncua (visually lossis ntawm cov ris tsho menyuam) yog qhov tseem ceeb heev. Kev tsis quav ntsej cov ntaub qhwv rau kev rotor kev puas tsuaj, ploj ntawm braking zog, thiab muaj peev xwm caliper kev puas tsuaj. Nco ntsoov hloov cov ntaub qhwv hauv qag teeb (ob qho tib si pem hauv ntej lossis ob sab nraub qaum). Lub chaw pw kom zoo -} hauv (cov txheej txheem tsim khoom lag luam) yog qhov tseem ceeb rau txheej txheem kev hloov tsim ntawm lub rotor.

Nres Past Technology txuas ntxiv mus sai, tsav los ntawm cov khoom science, ib puag ncig ua, thiab hloov tsheb architectures. Nkag siab txog cov khoom siv nyiaj txiag, hom, kev ua yeeb yam cov yam ntxwv, thiab xaiv cov neeg muaj feem xyuam rau kev txiav txim siab uas ua rau muaj kev nyab xeeb, kev ua tau zoo, thiab ib puag ncig cuam tshuam. Lub ncoo nres tsheb uas muaj kev txo hwj chim nres yog ib qho tseem ceeb thiab cov khoom tiv thaiv nyuaj ntawm lub plawv ntawm kev nyab xeeb kev nyab xeeb kev nyab xeeb.
