Nres thiab nres

Cov brakes yog lub luag haujlwm rau hloov lub zog kinetic rau hauv tshav kub. Thiab qhov cua sov no yog dissipated ntawm lub disc thiab nres nres.

Keeb kwm, disc brakes tau qhia hauv xyoo 1953 hauv lub tsheb. Tom qab ntawd lawv tau ua los ntawm chrome-plated steel los tiv thaiv tshav kub ntawm tus nqi ntawm cov coefficient ntawm kev sib txhuam. Nws yog nyob rau hauv thaum ntxov 1970s uas cov discs, pib sau, tau drilled nrog cua ducts. Txoj kab uas hla thiab thicknesses ces nce.

steel discs yog hloov nrog carbon discs; carbon discs muaj qhov zoo ntawm qhov hnyav (2 zaug sib dua li cov hlau) thiab tshwj xeeb tshaj yog nyob rau hauv qhov tseeb tias lawv tsis muaj qhov txo qis hauv kev ua haujlwm nyob ntawm qhov kub thiab txias. Koj yuav tsum paub tias thaum peb tham txog carbon discs, lawv yog cov sib tov ntawm ceramic fibers thiab carbon.

Tus nres nres

Cov no yog cov ntaub qhwv uas tuaj rau hauv kev sib cuag nrog lub brake disc thiab nres lub maus taus. Lawv cov ntaub ntawv tuaj yeem yog sintered hlau (encapsulated) lossis organic (ceramic).

Spacers yuav tsum tau xaiv raws li hom rim - cam khwb cia hlau, hlau lossis stainless hlau - thiab tom qab ntawd raws li hom maus taus, tsav tsheb, thiab siv koj xav ua tawm ntawm nws.

Organic: feem ntau thawj, lawv muaj li ntawm aramid fibers (xws li kevlar) thiab graphite. Lawv tsis nruj dua li cov hlau thiab hnav cov discs tsawg dua.

Lawv feem ntau pom zoo rau hauv nroog / txoj kev loj siv qhov twg cov brakes yog siv me ntsis.

Sintered hlau: Lawv yog tsim los ntawm cov hmoov hlau (bronze, tooj liab, hlau) thiab ceramic thiab graphite fibers, tag nrho cov ua los ntawm particle board ntawm kub / siab. Tshwj xeeb rau cov tsheb ua si / dej, lawv muaj zog dua braking thaum tsis tshua muaj siab rau qhov kub thiab txias. Yog tias lawv hnav tsawg dua, lawv hnyav dua kom hlawv. Yog li ntawd, nws yog ib qho tseem ceeb los xyuas seb cov discs yog tsim los txhawb cov sintered hlau daim hlau, txwv tsis pub cov discs yuav raug puas tsuaj.

Cov ntaub qhwv kuj txawv raws li lawv siv / qhov kub thiab txias: txoj kev 80 ° txog 300 °, kis las 150 ° txog 450 °, sib tw 250 txog 600 °.

Nco ntsoov! cov phaj tsis zoo heev kom txog thaum lawv ncav cuag qhov kub thiab txias. Yog li ntawd, txoj kev tsis tshua muaj siab txog 250 ° ... uas txhais tau hais tias kev sib tw hauv av yuav ua haujlwm tsawg dua li kev siv txhua hnub.

Kev hloov pauv ntau zaus

Lub neej ntawm cov ntaub qhwv yuav yog nyob ntawm seb lawv muaj pes tsawg leeg, tab sis tshwj xeeb tshaj yog nyob ntawm koj hom kev tsav tsheb thiab qhov zaus uas koj thov rau lub brakes. Kev cia siab thiab nres yuav maj mam txuas lub neej ntawm gaskets. Kuv hloov cov pawm tsuas yog tom qab 18 km ... "yog tias koj maj nrawm, koj yog neeg lim hiam" 😉

Nres disk

Nres pads tom hlau discs.

Cov discs no feem ntau muaj peb ntu:

1. khiav: ua los ntawm steel / stainless hlau los yog cam khwb cia hlau, hnav tawm, khawb tshaj kilometers.
2. Kev sib txuas: Nws muab kev sib txuas ntawm txoj kev khiav thiab cov fretboard los ntawm cov nplhaib lossis rivets. Qhov kev ua si tsim suab nrov ua haujlwm.
3. fret: kev txhawb nqa uas txuas lub maus taus mus rau txoj kab nres.

Nyob ntawm seb muaj pes tsawg qhov chaw thiab lawv cov qauv, peb tab tom tham txog disks:

• Tsau: nres khiav ua los ntawm tib yam khoom raws li fret
• Semi-floating: frets thiab lem yog ua los ntawm cov khoom sib txawv thiab yog riveted.
• Floating: lub nres khiav yog ua los ntawm cov khoom uas tsis yog fret; ob qho tib si txuas nrog lub nplhaib nruab nrab uas tawm ntawm txoj kev ywj pheej ntawm kev txav mus los ntawm lub disc: qhov siab tshaj plaws ntawm cov nres disc. Qhov no tso cai rau cov imperfections nyob rau hauv lub log thiab bearing clearance kom puv. Cov ntaub qhwv hauv nruab nrab kuj tso cai rau txoj hauv kev los tso nws tus kheej hauv txoj hauv kev zoo tshaj plaws hauv kev sib raug zoo nrog cov ntaub qhwv.

Cov hlau ntawm lub brake disc txiav txim siab cov ntaub qhwv yuav tsum tau siv. Stainless hlau disc yuav siv hlau phaj. Lub cam khwb cia hlau disc yuav siv cov paib organic. Conversely, cam khwb cia hlau disc tsis zam sintered hlau spacers.

Discs tuaj yeem ncav cuag 500 ° C kub dua! paub tias stainless hlau disc deforms saum 550 °.

Lub disc hnav tawm thiab hloov ib txwm tom qab 3-5 teev ntawm shims.

Tsis txhob hnov ​​​​qab xyuas lawv cov tsos thiab cov tsos ntawm microcracks.

Koj yuav tsum paub tias lub disc uas nyias dhau ua kom sov sai dua; nws cov hauj lwm zoo thiab endurance yog txo.

Nres calipers

Floating: xyuas thiab lubricate tag nrho cov axles, hloov cov hauv qab yog tias tsim nyog.

Tsau: Txheeb xyuas qhov dej ntws, Steer the Pads Axis

Tswv yim: Ntxuav cov discs thiab clamps nrog xab npum dej.

Nres hose

Lawv feem ntau yog ua los ntawm cov roj hmab. Tom qab ntawd nws yog txaus los xyuas kom meej tias tsis muaj cov kab nrib pleb vim muaj hnub nyoog, nruj thiab cov xwm txheej ntawm cov nres fittings.

Muaj cov hoses nrog Teflon core thiab stainless hlau braid thiab tom qab ntawd them nrog PVC sheath tiv thaiv.

Tswv kheej kheej

Txheeb xyuas nws qhov kev pom dav dav, qhov muaj peev xwm xau los yog dej (cov yeeb nkab, pom iav, piston foob) thiab qhov siab ntawm cov dej nres. Nws raug nquahu kom hloov cov dej nres txhua ob xyoos nyob rau hauv rooj plaub ntawm DOT4. Txhua xyoo yog DOT5.

Tswv yim:

Txheeb xyuas qhov xwm txheej ntawm cov ntaub qhwv tsis tu ncua. Ib txheej ntawm cov ntaub qhwv tus nqi tsuas yog tshaj 15 euros, tab sis cov ntaub ntawv raug nqi ntau dua 350 euros! Koj yuav tsum hloov cov phau ntawv ntawm ob lub discs tib lub sijhawm (txawm tias ib qho ntawm cov kev ua si tseem zoo li zoo).

Raws li nrog rau txhua qhov tshiab, yuav tsum tau saib xyuas tshwj xeeb thaum thawj ob peb mais kom muab lub sijhawm rau cov ntaub qhwv kom hloov mus rau cov discs. Nyob rau hauv luv luv, maj mam siv lub brakes: me ntsis repetitive thiab maj mam braking.

Sau tus nqi:

Nco ntsoov, sab laug thiab sab xis discs txawv thiab feem ntau txawv ntawm ib vintage mus rau lwm tus.

Kuj tseem muaj cov rims hloov tau nrog cov nqi poob qis dua 150 euros. Tab sis hav, tsis txhob cia siab tias qhov zoo ib yam!

Brochure nqi:

Hauv Fabkis cov khoom siv: € 19 (Dafy Moto)

Hauv Carbonne Lorraine: 38 euros (ref: 2251 SBK-3 pem hauv ntej rau 1200).

Tam sim no, yog tias koj txiav txim siab hloov txhua yam tib lub sijhawm thiab suav nrog kev ua haujlwm, nws yuav raug nqi koj nyob ib ncig ntawm € 100 suav nrog VAT (pem hauv ntej vaj huam sib luag teeb: 2 * 158,53 FHT, rear npog teeb: 142,61 FHT, mounting pob 94,52 FHT).
