Lub disc nres muaj ntau yam zoo uas tau ua kom nws siv tau rau hauv feem ntau ntawm cov tsheb:
- High thermal efficiency, raws li lub disk yuav luag tag nrho qhib thiab muaj rau cua txias los ntawm sab nraum cua.
- Simplicity thiab compact tsim.
- Yooj yim ntawm kev saib xyuas cov xwm txheej ntawm qhov hnav ntawm cov ntaub qhwv thiab cov discs.
- Muaj peev xwm siv qhov cua ntxiv nrog kev pab los ntawm cov qauv sab hauv ntawm lub disc thiab nws cov perforation.
- Tsawg rhiab heev rau cov av thiab ingress ntawm noo noo vim muaj tej yam kev mob zoo rau nws tus kheej tu.
Cov khoom siv rau cov discs feem ntau yog cam khwb cia hlau, uas muaj cov khoom zoo sib xws thiab lawv cov kev ruaj ntseg, tsis tshua muaj steel, thiab rau kev siv kis las, cov ntaub ntawv sib xyaw yog siv uas tso cai rau kev ua haujlwm ntawm qhov kub thiab txias yam tsis muaj zog thiab geometry.
Cov ntaub qhwv muaj cov hlau substrate, uas cov ntaub ntawv sib txhuam ua los ntawm cov khoom uas tau xaiv los ntawm ntau xyoo ntawm kev tshawb fawb tau kho nrog cov kua nplaum tshwj xeeb thiab molded spikes.
Qhov nyuaj ntawm no yog nyob rau hauv kev sib haum xeeb ntawm ntau yam tsis sib haum xeeb, siab coefficient ntawm kev sib txhuam ntawm cam khwb cia hlau thiab hlau, hnav tsis kam, muaj peev xwm los tiv thaiv discs los ntawm hnav, kub stability thiab tsawg kawg nkaus suab nrov acoustic.
Nruas brakes
Lawv suav nrog lub nruas nres nyob rau hauv daim ntawv ntawm lub tog raj kheej kaw ntawm ib sab thiab nres nres ua haujlwm ntawm lawv qhov chaw sab hauv.
Lub tog raj kheej hydraulic ua haujlwm kuj tseem nyob hauv; thaum koj nias lub pedal, lawv thawb cov ntaub sib cais, nias lawv tawm tsam cov nruas. Lub ncoo cheeb tsam tsuas yog me ntsis me dua lub puab cylindrical nto.
Kev siv cov txheej txheem no raug txwv, vim qee qhov kev tsis txaus ntseeg:
- txias imperfections, pads ua hauj lwm nyob rau hauv ib tug kaw kab noj hniav;
- tsis zoo tiv thaiv ntawm ob sab hauv thaum dej nkag mus rau hauv lub nres;
- qhov loj me thiab qhov hnyav ntawm tag nrho cov qauv.
Nyob rau tib lub sijhawm, cov nruas muaj lawv tus kheej zoo, tshwj xeeb tshaj yog tiv thaiv kev sib kis, kev ua haujlwm ntev thiab kev siv tshuab yooj yim ntawm kev tsim khoom.
Vim li cas cov pawm nres, discs thiab nruas hnav tawm
Kev sib txhuam, ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov brakes, muaj cov ntsiab lus zoo ntawm lub cev. Qhov no yog ib qho kev sib tsoo ntawm me ntsis irregularities, roughness ntawm rubbing nto, uas tsis tas yuav nyob twj ywm yam tsis muaj txim rau lawv.
Thiab cov txiaj ntsig no yog qhov sadder, qhov siab dua coefficient ntawm kev sib txhuam, uas yog, lub tshuab nres sai dua. Peb yuav tsum xaiv qhov kev sib haum xeeb ntawm qhov zoo ntawm braking thiab durability ntawm qhov chaw.
Raws li kev paub ntau xyoo, cov ntaub ntawv hauv ob sab phlu thiab cov ntaub ntawv disc raug xaiv raws li qhov nruab nrab disc tuaj yeem muaj sia nyob peb lossis plaub pawg ntawm cov ntaub qhwv. Qhov no yog qhov zoo tshaj plaws nyob rau hauv cov nqe lus ntawm qhov piv ntawm tus nqi ntawm ib tug loj heev thiab kim disc rau tus nqi ntawm tus nqi pheej yig pads, uas yog xam tau tias yog consumables.
Ua rau hnav ceev
Txo kev pab cuam lub neej ntawm kev sib txhuam cov ntsiab lus yog tshwm sim los ntawm ntau yam.
- Kev caij. Nws yog ib qho tseem ceeb uas nrog kev siv cov pedal nquag, hnav yuav mus sai dua, tshwj xeeb tshaj yog tias cov brakes tsis muaj sijhawm txias.
- Deviations nyob rau hauv cov khoom ntawm cov khoom. Tsis yog ib txwm muaj kev hloov pauv tam sim no, discs (nruas) thiab cov ntaub qhwv ntsej raug ntsia raws nraim tib yam li lawv nyob hauv lub hoobkas. Cov discs tuaj yeem tsim los ntawm cov hlau cam khwb cia ntawm qhov sib txawv hardness thiab carbon cov ntsiab lus, thiab cov ntaub qhwv yog tsim los ntawm kev siv cov thev naus laus zis sib txawv, siv cov khoom siv tsoos tsis muaj asbestos, suav nrog cov hlau lossis cov organic fibers. Yog li ntawd, nws yog qhov ua tau, nrog kev ua haujlwm sib npaug hauv ntau qhov sib xyaw ua ke, hloov cov ntaub qhwv los yog discs ntau zaus.
- Cov av ntawm qhov chaw ua haujlwm. Plua plav thiab xuab zeb ua hauj lwm raws li abrasives, uas accelerates hnav.
- Disc corrosion thiab hauv ob sab phlu khoom degradation. Lawv tuaj yeem tshwm sim ob qho tib si vim tsis tshua muaj kev siv cov brakes, thiab rov ua dua, tas li overheating.
- Malfunctions ntawm cov lus qhia apparatus ntawm tus nres. Cov ntaub qhwv yuav tsis nias tusyees, ua rau tsis zoo ib leeg hnav.
- Log bearing teeb meemthaum lub log backlash ua rau tsis tu ncua ntawm cov ntaub qhwv ntawm lub disc.
- Kev ua txhaum cai hauv kev tswj qhov khoob. Tsis saib xyuas ntawm kev hloov lub nruas nres lossis kev hloov pauv ntawm pistons hauv disc nres.
Raws li koj tuaj yeem pom, kev hnav nrawm tuaj yeem tshwm sim ob qho tib si vim li cas thiab los ntawm tus neeg tsav tsheb tsis txaus siab.
Vim li cas ho tsis hnav ntawm qhov chaw tshwm sim
Qhov no feem ntau yog vim kev txhim kho sab hauv ntawm cov pistons thiab lub tog raj kheej hauv hydraulic tsav. Tshwj xeeb tshaj yog nyob rau hauv multi-piston mechanisms. Kuj tseem muaj souring nyob rau hauv phau ntawv qhia apparatus ntawm lub caliper.
Lub bracket warps, ua rau cov ntaub qhwv yuav tsum nias nyuaj ntawm ib ntug dua li lwm qhov. Lub caliper yuav tsum tau disassembled, ntxuav thiab lubricated, tiv thaiv lub lubricant los ntawm kev sib txhuam nto. Tab sis nws yog qhov zoo dua los hloov qhov chaw.
Dab tsi yog qhov txaus ntshai ntawm hnav ntawm qhov chaw ntawm lub nres system
Thaum cov khoom mus txog qhov tseem ceeb, qhov kev ua haujlwm ntawm lub braking poob, uas tsis yog ib txwm pom tau vim yog cov khoom khaws cia hauv lub braking system. Qhov no yog ib qho kev dag ntxias, cov brakes tuaj yeem ua tsis tau sai sai nrog qhov tshwm sim tsis tuaj yeem.
Ntawm qhov siab tshaj plaws ntawm cov ntaub qhwv ntsej muag, nrog kev hnav tsis tau, cov pistons txuas mus deb dhau ntawm lub tog raj kheej, poob rau hauv corroded, yav tas los tsis siv. Muaj qhov tshwm sim siab ntawm jamming nrog avalanche zoo li nce hauv hnav thiab ua tsis tiav.
Qhov no yog exacerbated los ntawm ib tug txo nyob rau hauv lub thickness ntawm lub disk hauv qab no cov kev txwv. Txhua lub tsheb muaj nws tus qauv yam tsawg kawg nkaus, uas yuav tsum tau tswj ntawm txhua qhov kev saib xyuas.
Tshawb xyuas cov ntaub qhwv tsis tau tshem lub log
Nws tsis yog ib txwm ua tau qhov no yam tsis tau tshem lub log. Lub disc yuav tsum muaj qhov deb txaus ntawm cov spokes los muab kev tswj qhov muag. Qee zaum koj yuav tsum siv daim iav thiab lub teeb nyem.
Yog tias peb xav txog thaj tsam ntawm kev sib cuag ntawm lub ncoo thiab lub disc, ces nyob rau hauv lub teeb pom kev zoo koj tuaj yeem pom qhov loj ntawm kev sib txhuam hauv ob sab phlu ntawm lub ncoo substrate.
Feem ntau qhov txwv tus nqi yog 2-3 hli. Nws yog qhov txaus ntshai rau kev tsav tsheb mus ntxiv. Thiab nws yog qhov zoo dua tsis coj nws mus rau tus nqi no, tom qab qhov seem 4 hli nws yog lub sijhawm los hloov cov ntaub qhwv.
Qhov teeb meem yog qhov nyuaj ntxiv los ntawm qhov yuav luag tiav qhov tsis muaj tseeb ntawm kev ntsuam xyuas cov ntaub qhwv sab hauv zais hauv qab caliper.
Txawm hais tias nws tuaj yeem pom los ntawm qhov kawg ntawm lub disk, qhov no yuav muab cov ntaub ntawv me me, cheeb tsam no hnav tsis sib xws, thiab tseem muab zais los ntawm ntug tsim thaum hnav ntawm lub voj voog ntawm lub disk. Ntawd yog, nrog kev hnav tsis sib xws ntawm cov ntaub qhwv, kawm tsuas yog sab nrauv yuav tsis muab dab tsi.
Hmoov zoo, cov neeg tsim qauv feem ntau muab qhov ntsuas hluav taws xob lossis acoustic hnav txwv. Lub thaiv pib creak yam ntxwv los yog teeb rau qhov taw qhia ntawm lub dashboard.
Cov lus pom zoo rau kev hloov cov pawm nres
Tus tsim ntawm lub brakes ntawm tag nrho cov tshuab yog zoo sib xws, yog li cov nram qab no nta ntawm kev saib xyuas ntawm cov units yuav txawv.
- Cov ntaub qhwv ib txwm hloov pauv hauv cov teeb tsa ntawm tib lub qag. Nws yog qhov tsis tsim nyog los hloov lawv ib zaug nrog kev hnav tsis sib xws.
- Thaum hloov cov ntaub qhwv, nws yog ib qho tsim nyog yuav tau lubricate lawv tag nrho cov cuab yeej qhia nrog qhov tshwj xeeb kub muaj pes tsawg leeg.
- Kev kuaj xyuas yuav tsum tau ua raws li kev ywj pheej ntawm kev txav ntawm cov piston hauv lub tog raj kheej hydraulic.
- Nyob rau hauv cov ntaub ntawv ntawm tsis sib xws ntawm lub disc los yog tshaj qhov txwv ntawm nws geometry, lub disc yuav tsum tau hloov unconditionally.
- Thaum thawb lub pistons nyob rau hauv cov ntaub qhwv tshiab, kev ntsuas yuav tsum tau ua kom ywj siab nce cov kua dej hauv lub tog raj kheej lub tog raj kheej, thiab tom qab ntawd coj cov qib mus rau qhov qub.
- Thawj zaug koj nias lub pedal tom qab txhim kho lub ncoo, nws ntog los ntawm, yog li koj tsis tuaj yeem tawm mus yam tsis tau nias lub nres ob peb zaug.
- Thaum xub thawj, cov ntaub qhwv yuav khiav hauv, yog li qhov ua tau zoo ntawm cov brakes yuav tsis rov qab los tam sim ntawd.
- Tsheb qag nruas mechanisms yuav tsum tau kho tus brake.
Yuav tsis muaj qhov tsis txaus ntseeg hauv kev saib xyuas ntawm lub tshuab nres. Tsis txhob cia siab tias kev hloov cov ntaub qhwv yuav daws tau txhua yam teeb meem.
Nyob rau hauv tshwj xeeb tshaj yog cov mob hnyav, koj yuav tsum tau hloov kho tag nrho cov ntsiab lus ntawm lub cev, hoses, dej ua haujlwm, mus txog rau kev hloov cov calipers, txawm tias nws kim npaum li cas. Txawm li cas los xij, qhov tshwm sim yuav kim dua.
