Dab tsi yog qhov hnav ntawm cov brakes
Txhua tus neeg nyiam lub tsheb yuav tsum paub tias hom nres disc hnav zoo li cas, uas lawv tuaj yeem ua haujlwm nyab xeeb, thiab qhov twg yog qhov txwv, thiab nws tsim nyog hloov cov discs.
Qhov tseeb yog tias qhov siab tshaj plaws hnav ntawm cov nres discs dhau lawm, muaj peev xwm ua rau muaj xwm txheej ceev. Yog li, nyob ntawm tus qauv tsim ntawm lub nres nres, lub nres piston tuaj yeem cuam tshuam los yog tsuas yog poob ntawm nws lub rooj. Thiab yog tias qhov no tshwm sim ntawm kev kub ceev - nws yog qhov txaus ntshai heev!
Tso cai hnav ntawm cov brakes
Yog li, dab tsi yog qhov tso cai hnav ntawm cov brakes? Hnav tus nqi rau cov brakes yog tsim los ntawm txhua qhov chaw tsim khoom. Cov kev txwv no nyob ntawm lub cav fais fab ntawm lub tsheb, qhov loj thiab hom nres discs. Kev txwv hnav yuav txawv rau ntau hom discs.
Piv txwv li, lub thickness ntawm ib tug tshiab nres disc rau cov nrov Chevrolet Aveo yog 26 hli, thiab tseem ceeb heev hnav tshwm sim thaum tus nqi coj mus rau 23 hli. Raws li, qhov tso cai hnav ntawm tus nres disc yog 24 hli (ib chav nyob ntawm txhua sab). Nyob rau hauv lem, disc manufacturers muab cov ntaub ntawv hais txog qhov hnav txwv ntawm qhov chaw ua hauj lwm ntawm lub disc.
Qhov no yog ua tiav siv ib qho ntawm ob txoj kev. Thawj yog ib daim ntawv sau ncaj qha rau ntawm ntug. Piv txwv li, MIN. TH. 4 hli. Lwm txoj kev yog lub cim nyob rau hauv daim ntawv ntawm ib tug notch nyob rau hauv lub kawg ntawm lub disk, tab sis nyob rau hauv nws sab hauv (kom lub block tsis txhob ntaus nws). Raws li kev xyaum qhia, txoj kev thib ob yog yooj yim dua, vim hais tias nrog kev nce hauv kev hnav mus txog qhov tseem ceeb, lub disk pib nres hauv jerks, uas yuav pom meej meej los ntawm tus neeg tsav tsheb thaum nres.
Raws li lub nruas nres discs, lawv tsis txo qis thaum lawv hnav, tab sis nce hauv lawv txoj kab uas hla. Yog li ntawd, txhawm rau txiav txim siab seb lawv hnav zoo li cas, koj yuav tsum tau kuaj xyuas lub puab kab uas hla thiab saib seb nws tsis dhau qhov kev tso cai. Qhov siab tshaj plaws tso cai ua haujlwm txoj kab uas hla ntawm lub nruas nres yog stamped ntawm nws sab hauv. feem ntau nws yog 1-1,8 hli.
Ntau qhov kev pab cuam hauv Is Taws Nem thiab hauv qee lub khw muag khoom pib qhia tias nres disc hnav yuav tsum tsis pub tshaj 25%. Qhov tseeb, hnav yog ib txwm ntsuas nyob rau hauv cov units, uas yog, nyob rau hauv millimeters! Piv txwv li, ntawm no yog ib lub rooj zoo ib yam li cov uas tau muab rau ntau lub tsheb hauv lawv cov ntaub ntawv.
| Parameter npe | Nqe, mm |
|---|---|
| Nominal nres disc thickness | 24,0 |
| Yam tsawg kawg nkaus disc thickness ntawm qhov siab tshaj plaws hnav | 21,0 |
| Qhov siab tshaj plaws tso cai hnav ntawm ib qho ntawm cov dav hlau disc | 1,5 |
| Qhov siab tshaj plaws disc runout | 0,04 |
| Yam tsawg kawg nkaus admissible thickness ntawm kev sib txhuam hauv ob sab phlu ntawm cov khau nres | 2,0 |
Yuav ua li cas txiav txim siab hnav ntawm cov brakes
Kev kuaj xyuas tus brake disc hnav tsis yog qhov nyuaj, qhov tseem ceeb yog kom muaj lub caliper lossis micrometer ntawm tes, thiab yog tias tsis muaj cov cuab yeej zoo li no, tom qab ntawd qhov xwm txheej hnyav koj tuaj yeem siv tus pas ntsuas lossis npib (ntxiv rau hauv qab no). Lub thickness ntawm lub disc yog ntsuas ntawm 5 ... 8 cov ntsiab lus nyob rau hauv ib lub voj voog, thiab yog hais tias nws hloov, ces nyob rau hauv tas li ntawd mus rau lub hnav ntawm lub nres cheeb tsam, muaj curvature los yog unevenness hnav. Yog li ntawd, nws yuav tsim nyog tsis tsuas yog hloov nws ntawm qhov txwv, tab sis kuj yuav tsum paub tias yog vim li cas vim qhov tsis sib xws ntawm cov nres disc tshwm sim.
Yuav kuaj li cas
Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws nws yog qhov zoo tshaj plaws kom tshem tawm lub log, vim tias qhov tuab ntawm lub disc tsis tuaj yeem ntsuas lwm yam, thiab yog tias koj xav tau xyuas qhov hnav ntawm lub nruas nres tom qab, koj yuav tsum tshem tawm tag nrho. nres mechanism. Thaum ua tiav kev kuaj xyuas ntxiv, nws yuav tsum tau coj mus rau hauv tus account tias cov disks hnav tawm ntawm ob sab - sab nraud thiab sab hauv. Thiab tsis yog ib txwm sib npaug, yog li koj yuav tsum paub txog qib kev hnav ntawm lub disk ntawm ob sab ntawm lub disk, tab sis ntau ntxiv rau hauv qab no.
Ua ntej kuaj xyuas, koj yuav tsum paub cov ntaub ntawv hais txog qhov tuab ntawm cov nres nres tshiab rau ib lub tsheb tshwj xeeb. Nws tuaj yeem pom nyob rau hauv cov ntaub ntawv thev naus laus zis lossis hauv disk nws tus kheej.
Txwv tsis pub hnav ntawm cov brakes
Tus nqi ntawm qhov siab tshaj plaws tso cai hnav yuav nyob ntawm qhov loj me ntawm lub disk thiab lub zog ntawm lub tsheb sab hauv combustion engine. Feem ntau, tag nrho hnav ntawm tag nrho cov disc rau cov neeg caij tsheb yog li 3 ... 4 hli. Thiab rau cov dav hlau tshwj xeeb (sab hauv thiab sab nraud) txog 1,5 ... 2 hli. Nrog xws li hnav, lawv twb yuav tsum tau hloov. Rau cov brakes uas muaj ib lub dav hlau (feem ntau yog ntsia ntawm lub tsheb nres), cov txheej txheem yuav zoo sib xws.
Kev kuaj xyuas qhov hnav ntawm cov brake discs suav nrog kev kuaj xyuas qhov tuab ntawm ob lub dav hlau ntawm lub disc, qhov loj ntawm lub xub pwg nyom, thiab tom qab ntawd muab cov ntaub ntawv no sib piv nrog tus nqi nominal uas lub disc tshiab yuav tsum muaj, lossis cov kev pom zoo. kuj ntsuam xyuas qhov dav dav ntawm kev puas tsuaj ntawm thaj chaw ua haujlwm ntawm lub disk, uas yog, kev tsis sib xws, muaj cov grooves thiab cov kab nrib pleb (qhov loj ntawm qhov tawg yuav tsum tsis pub tshaj 0,01 hli).
Thaum lub sij hawm soj ntsuam, koj yuav tsum tau saib qhov loj ntawm cov grooves ntawm kev ua hauj lwm thiab lawv cov qauv. Cov grooves me me yog ib txwm hnav. Nws raug nquahu kom hloov cov discs ua ke nrog cov ntaub qhwv yog tias muaj qhov sib sib zog nqus grooves. Nyob rau hauv cov ntaub ntawv ntawm conical hnav ntawm lub nres disc, nws yog tsim nyog los hloov nws thiab xyuas lub nres caliper. Yog hais tias cov kab nrib pleb los yog lwm yam corrosion thiab discoloration pom nyob rau hauv lub disc, nws yog feem ntau txuam nrog thermal phenomena uas tshwm sim vim tsis tu ncua thiab ntau dhau ntawm qhov kub thiab txias ntawm lub disc. Lawv ua rau braking nrov thiab txo braking efficiency. Yog li ntawd, nws kuj yog qhov tsim nyog los hloov cov disk thiab nws yog qhov tsim nyog los txhim kho cov khoom zoo dua nrog kev txhim kho cua sov.
Nco ntsoov tias thaum lub disc hnav, ib qho ntug tsim nyob ib ncig ntawm lub voj voog (cov ntaub qhwv tsis rub rau nws). Yog li ntawd, thaum ntsuas, nws yog ib qho tsim nyog los ntsuas qhov chaw ua haujlwm. Nws yooj yim dua ua qhov no nrog lub micrometer, vim tias nws cov "circling" ua haujlwm tso cai rau koj tsis txhob kov nws. Nyob rau hauv cov ntaub ntawv ntawm kev siv ib tug caliper, nws yog tsim nyog los tso tej yam khoom nyob rau hauv nws gauges, lub thickness ntawm uas coincides nrog rau hnav ntawm cov ntaub qhwv (piv txwv li, daim ntawm tin, hlau npib, thiab lwm yam).
Yog hais tias tus nqi ntawm lub thickness ntawm lub disk tag nrho los yog ib qho ntawm nws cov dav hlau qis dua tus nqi tso cai, lub disk yuav tsum tau hloov nrog ib qho tshiab. Yuav tsum tsis txhob siv lub nres nres nres!
Yog tias koj tsis muaj lub micrometer ntawm tes, thiab nws tsis yooj yim los xyuas nrog lub caliper vim muaj ib sab, koj tuaj yeem siv lub npib hlau. Piv txwv li, raws li tus nom Central Bank ntawm Russia, lub thickness ntawm ib npib nrog lub ntsej muag tus nqi ntawm 50 kopecks thiab 1 ruble yog 1,50 hli. Rau lwm lub tebchaws, cov ntaub ntawv tseem ceeb tuaj yeem nrhiav pom ntawm cov vev xaib raug cai ntawm lub tsev txhab nyiaj hauv nruab nrab ntawm cov tebchaws.
Txhawm rau txheeb xyuas qhov tuab ntawm lub nres nres nrog lub npib, koj yuav tsum muab nws tso rau ntawm qhov chaw ua haujlwm ntawm lub disc. Feem ntau, qhov tseem ceeb ntawm ib qho chaw disk yog nyob rau hauv 1,5 ... 2 hli. Siv lub caliper, koj tuaj yeem pom qhov hnav tuab ntawm ob qho tib si ib nrab ntawm cov disk thiab tag nrho cov tuab ntawm tag nrho cov disk. Yog tias ntug tsis hnav tawm, koj tuaj yeem ntsuas ncaj qha los ntawm nws.
Dab tsi cuam tshuam rau nres disc hnav?
Lub degree ntawm hnav ntawm cov brakes yog nyob ntawm ntau yam. Ntawm lawv:
- Tsav tsheb style ntawm tus neeg nyiam tsheb. Lawm, nrog nquag braking nyuaj, ntau disc hnav thiab nres ncoo hnav tshwm sim.
- Cov kev ua haujlwm ntawm lub tsheb. Nyob rau hauv roob lossis toj roob hauv pes, cov brakes hnav sai dua. Qhov no yog vim ntuj tsim, txij li thaum lub nres system ntawm xws li tsheb yog siv ntau zaus.
- Hom sib kis. Ntawm cov tsheb uas muaj kev sib kis ntawm phau ntawv, cov discs, zoo li cov ntaub qhwv, tsis hnav sai li sai tau. Conversely, nyob rau hauv lub tsheb nruab nrog ib tug tsis siv neeg kis tau tus mob los yog ib tug variator, disc hnav tshwm sim sai dua. Qhov no tau piav qhia los ntawm qhov tseeb tias txhawm rau kom nres lub tsheb nrog kev sib kis tsis siv neeg, tus neeg tsav tsheb raug yuam kom siv lub tshuab nres nkaus xwb. Thiab lub tsheb nrog "mechanics" feem ntau tuaj yeem ua rau qeeb qeeb vim lub tshuab hluav taws xob sab hauv.
- Hom nres discs. Tam sim no, cov nram qab no cov brakes discs yog siv rau cov neeg nrog caij tsheb: ventilated, perforated, notched discs, thiab khoom discs. Txhua hom no muaj nws tus kheej zoo thiab qhov tsis zoo. Txawm li cas los xij, raws li kev xyaum qhia, cov khoom siv tsis tau nrawm tshaj plaws, thaum lub tshuab cua thiab perforated discs ntev dua.
- Hnav chav kawm. Nws ncaj qha nyob ntawm tus nqi thiab hom disk qhia saum toj no. Ntau tus neeg tsim khoom tsuas yog qhia qhov tsawg kawg nkaus mais rau lub tsheb uas tus nres disc tsim los ntawm chav kawm hnav tsis kam.
- Nres ncoo hardness. Lub softer lub brake ncoo, lub softer nws ua hauj lwm nrog lub disc. Ntawd yog, cov peev txheej disk nce. Nyob rau hauv cov ntaub ntawv no, lub braking ntawm lub tsheb yuav smoother. Hloov pauv, yog tias lub ncoo nyuaj, ces nws hnav tawm lub disc sai dua. Braking yuav ntse dua. Qhov zoo tshaj plaws, nws yog qhov xav tau tias cov chav kawm hardness ntawm lub disc thiab cov chav kawm hardness ntawm cov ntaub qhwv zoo sib xws. Qhov no yuav txuas ntxiv lub neej ntawm tsis tsuas yog lub nres nres, tab sis kuj lub nres nres.
- Tsheb hnyav. Feem ntau, cov tsheb loj (xws li crossovers, SUVs) yog nruab nrog cov kab loj dua discs thiab lawv cov nres nres yog qhov muaj zog dua. Txawm li cas los xij, nyob rau hauv cov ntaub ntawv no, nws tau qhia tias lub tsheb thauj khoom (uas yog, nqa cov khoom thauj ntxiv lossis nqa lub tsheb hnyav) nres discs hnav sai dua. Qhov no yog vim qhov tseeb tias yuav tsum nres lub tsheb thauj khoom, koj xav tau ntau lub zog uas tshwm sim hauv lub tshuab nres.
- Qhov zoo ntawm cov khoom siv disc. Feem ntau, pheej yig nres discs yog ua los ntawm cov hlau tsis zoo, uas hnav tawm sai dua, thiab tseem tuaj yeem muaj qhov tsis xws luag thaum lub sijhawm (curvature, sagging, tawg). Thiab raws li, qhov zoo dua cov hlau los ntawm qhov no los yog qhov disk yog tsim, nws yuav kav ntev dua ua ntej hloov.
- Serviceability ntawm lub nres system. Kev ua tsis tiav xws li teeb meem nrog lub tog raj kheej ua haujlwm, cov lus qhia caliper (nrog rau qhov tsis muaj lubrication nyob rau hauv lawv), qhov zoo ntawm cov dej nres tuaj yeem cuam tshuam rau kev hnav ntawm cov brakes sai.
- Lub xub ntiag ntawm anti-lock system. ABS system ua haujlwm ntawm lub hauv paus ntsiab lus ntawm optimizing lub zog ntawm lub ncoo nias ntawm lub nres disc. Yog li ntawd, nws ncua lub neej ntawm ob lub ncoo thiab discs.
Thov nco ntsoov tias feem ntau qhov hnav ntawm lub hauv ntej nres discs ib txwm tshaj qhov hnav ntawm lub nraub qaum, vim lawv raug quab yuam ntau dua. Yog li ntawd, cov kev pab cuam ntawm lub hauv ntej thiab nram qab nres discs yog txawv, tab sis nyob rau tib lub sij hawm muaj ntau yam kev cai rau hnav kam rau ua!
Qhov nruab nrab, rau tus qauv tsheb neeg caij tsheb siv hauv nroog, kev kuaj xyuas disk yuav tsum tau ua kwv yees li ntawm 50 ... 60 txhiab kilometers. Kev tshuaj xyuas tom ntej thiab ntsuas kev hnav yog ua tiav nyob ntawm qhov feem pua ntawm kev hnav. Ntau cov discs niaj hnub rau cov neeg nrog caij tsheb yooj yim ua haujlwm rau 100 ... 120 txhiab kilometers nyob rau hauv nruab nrab kev ua haujlwm.
Yog vim li cas rau qhov tsis sib xws ntawm cov brakes
Qee lub sij hawm thaum hloov cov brakes, koj tuaj yeem pom tias cov qub tau hnav tsis sib xws. Ua ntej txhim kho cov discs tshiab, koj yuav tsum txheeb xyuas cov laj thawj vim li cas lub brake disc hnav tsis sib xws, thiab, raws li, tshem tawm lawv. Lub uniformity ntawm disc hnav zoo heev cuam tshuam rau kev ua haujlwm braking! Yog li, kev hnav tsis sib xws ntawm tus brake disc tuaj yeem tshwm sim los ntawm cov hauv qab no:
- Khoom tsis zoo. Muaj tsawg zaus, tshwj xeeb tshaj yog rau pheej yig nres discs, lawv tuaj yeem ua los ntawm cov khoom siv tsis zoo lossis tsis ua raws li cov cuab yeej tsim nyog.
- Kev teeb tsa tsis raug ntawm cov nres discs. Feem ntau, qhov no yog banal distortion. Qhov no yuav ua rau conical disc hnav nrog rau qhov tsis sib xws ntawm tus nres nres. Thaum pib, lub disc tuaj yeem raug tho, tab sis nws tseem zoo dua los hloov cov disc nrog ib qho tshiab.
- Kev teeb tsa tsis raug ntawm cov pawm nres. Yog hais tias ib qho ntawm cov ntaub qhwv tau ntsia crookedly, ces, raws li, hnav yuav tsis sib xws. Tsis tas li ntawd, ob qho tib si disc thiab lub brake ncoo nws tus kheej yuav hnav tsis sib xws. Qhov no yog vim li cas yog ib qho tseem ceeb rau twb hnav nres discs, vim hais tias cov ntaub qhwv hnav tawm sai dua li cov disc.
- Cov av nkag mus rau hauv lub caliper. Yog hais tias lub nres caliper tiv thaiv khau boots puas, cov khib nyiab me me thiab dej yuav nkag mus rau qhov chaw txav mus. Yog li, yog tias muaj teeb meem hauv kev txav mus los (tsis sib xws, mob stroke, souring) hauv lub tog raj kheej ua haujlwm thiab cov lus qhia, ces qhov sib xws ntawm lub ncoo quab yuam nyob rau thaj tsam ntawm disk cuam tshuam.
- Curve qhia. Tej zaum nws yuav tsis sib npaug vim yog kev teeb tsa tsis raug ntawm cov pawm nres lossis kev puas tsuaj rau cov khoom siv. Piv txwv li, raws li ib tug tshwm sim ntawm kev kho ntawm lub nres system los yog kev huam yuaj.
- Kev xeb. Qee qhov xwm txheej, piv txwv li, tom qab lub sijhawm ntev ntawm kev tsis ua haujlwm ntawm lub tsheb hauv huab cua nrog cov av noo siab, lub disc yuav dhau los ua corroded. Vim yog nws, lub disk tuaj yeem hnav tsis sib xws thaum ua haujlwm ntxiv.
Thov nco ntsoov tias nws yog qhov ua tau, tab sis tsis pom zoo, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam nws nws yog qhov tsim nyog yuav tsum tau txiav txim siab. Nws nyob ntawm nws tus mob, qib ntawm hnav, nrog rau cov txiaj ntsig ntawm cov txheej txheem. Qhov tseeb tias lub disk muaj qhov curvature yuav tshwm sim los ntawm lub khob uas tshwm sim thaum braking. Yog li ntawd, ua ntej sib tsoo cov grooves los ntawm qhov chaw ntawm lub disc, nws yog ib qho tsim nyog yuav tsum ntsuas nws cov dej ntws thiab hnav. Tus nqi nkag ntawm lub disc curvature yog 0,05 hli, thiab lub runout tshwm twb nyob rau ntawm ib tug curvature ntawm 0,025 hli.. Cov tshuab tso cai rau koj zom cov disc nrog kev kam rau siab ntawm 0,005 hli (5 microns)!
xaus
Kev hnav ntawm cov brake discs yuav tsum tau kuaj xyuas txhua txhua 50 ... 60 txhiab kilometers, los yog muaj teeb meem tshwm sim nyob rau hauv lub lag luam ntawm lub tsheb lub braking system. Txhawm rau txheeb xyuas tus nqi hnav, koj yuav tsum tau tshem lub disc thiab siv lub caliper lossis micrometer. Rau cov neeg caij tsheb niaj hnub feem ntau, qhov kev tso cai disc hnav yog 1,5 ... 2 hli ntawm txhua lub dav hlau, lossis txog 3 ... 4 hli hla tag nrho cov tuab ntawm cov disc. Hauv qhov no, nws yog ib txwm tsim nyog los ntsuas qhov hnav ntawm lub dav hlau sab hauv thiab sab nraud ntawm cov disks. Sab hauv ntawm lub disc ib txwm muaj me ntsis hnav ntau dua (los ntawm 0,5 hli).
