Qhov teeb meem loj tshaj plaws uas tuaj yeem tshwm sim hauv lub kaw lus nres ntawm lub tsheb yog kev vibration thaum nres. Vim li no, nyob rau hauv qhov xwm txheej hnyav, lub tsheb tsuas yog tsis nres thaum lub sijhawm, thiab kev sib tsoo yuav tshwm sim. Cov kws tshaj lij ntaus nqi rau qhov tseeb tias thaum muaj xwm txheej ceev, tus neeg tsav tsheb yuav ntshai ntawm kev ntaus hauv lub kauj thiab pedals thiab yuav tsis muaj zog ntawm kev nias lub nres. Qhov phem tshaj qhov teeb meem no tsuas yog ib qho kev ua haujlwm tsis siv neeg ua haujlwm nkaus xwb. Muaj ob peb lub laj thawj tseem ceeb rau tus cwj pwm ntawm lub tsheb no - cov teeb meem pom tau yuav tsum tau kho tam sim ntawd. Txoj kev nyab xeeb nyob ntawm nws.

Yuav ua li cas thiaj paub kev vibrations?

Ob lub nres nres thiab lub kauj tsheb feem ntau khob - nws zoo li lub kaw lus tiv thaiv kev cuam tshuam hauv cov txheej txheem nres. Koj tuaj yeem ntes cov kev vibrations thaum nres ntawm qhov qhuav thiab txawm nto.

Nws yog qhov zoo tshaj los sim lub tsheb rau kev co ntawm asph alt. Tom qab ntawd ABS, yog tias nws nyob hauv lub tsheb, yuav tsis cuam tshuam rau cov txheej txheem. Nws yog ib qho tsim nyog yuav tsum tau ceev mus rau 80 km / h, thiab tom qab ntawd maj mam, tab sis tsis muaj kev thaiv lub log, pib qeeb. Yog tias muaj cov yam ntxwv vibration thaum braking, ces koj yuav tsum xav txog kev kho.

Ua rau vibrations ntawm tus brake pedal

Qhov tshwm sim tsis zoo no tuaj yeem tshwm sim rau ntau yam. Feem ntau, cov kws tshaj lij nco ntsoov nres discs, nres nruas. Tsawg zaus (tab sis kuj yuav tsum tsis txhob txiav tawm), huab cua pom nyob rau hauv cov kab ntawm lub nres system. Qee lub sij hawm yog vim li cas lub log tsheb tsis zoo, lub log tsis sib xws. Crooked wheels kuj yog qhov kev vibration ntawm lub kauj thaum braking. Tsis tshua muaj teeb meem nrog kev ua haujlwm ntawm lub kaw lus tiv thaiv, txawm li cas los xij, qhov kev ua haujlwm tsis zoo no tau yooj yim kuaj los ntawm lub tsheb ECU. Ntawm cov laj thawj, cov khoom hnav yuav tsis raug txiav txim siab.

Nres ncoo corrosion

Lub tsheb yog ua los ntawm hlau, tab sis hlau corrodes. Txawm hais tias lub tsheb tau khaws cia hauv qhov chaw sov, koj yuav tsum tsis txhob xav tias nws tsis xeb. Yog tias lub tsheb tau sawv ntev ntev, ces corrosion tshwm nyob rau hauv qhov chaw uas cov ntaub qhwv tuaj rau hauv kev sib cuag nrog cov discs. Hauv qhov no, thaum thawj zaug sim nres, kev vibration ntawm tus nres pedal thaum lub sijhawm braking yog pom meej meej. Qee zaum qhov teebmeem no ploj mus ntawm nws tus kheej. Tab sis feem ntau cov disc thiab cov ntaub qhwv yuav tsum tau hloov.

paj tsis zoo

Dhau li ntawm corrosion, lawv tsuas yog tsis zoo. Niaj hnub no, kev sib yuav yog ib qho yooj yim. TABSISYog hais tias cov discs tsis zoo heev, ces txheej ua hauj lwm ntawm lub block yuav hnav tsis sib xws. Ntawm qee cov ntaub qhwv, qhov sib txhuam hauv ob sab phlu crumbles nyob rau hauv tag nrho cov pieces. Kev vibration ntawm lub kauj tsheb thaum lub sijhawm braking tshwm sim los ntawm kev xoob haum ntawm cov ntaub qhwv thiab cov disc.

Hloov lub geometry ntawm tus nres disc

Qhov no yog lwm qhov laj thawj uas ua rau muaj kev vibrations ntawm tus brake pedal thiab lub kauj tsheb. Nws muaj nyob rau hauv ib tug ntse txias ntawm lub disk. Thaum tus neeg tsav tsheb muaj kev tsav tsheb nruj heev thiab txav mus los ntawm ib lub teeb tsheb mus rau lwm qhov, cov discs tsuas yog tsis muaj sijhawm kom txias. Tab sis overheating kuj tuaj yeem tshwm sim thaum tsav tsheb ntsiag to vim lub caliper, uas tsis tuaj yeem muab kev tshem tawm txaus ntawm cov ntaub qhwv thiab cov disc.

Yog tias lub tsheb tsav mus rau hauv lub pas dej, tus brake disc txias heev thiab tawg lossis deforms. Tom qab xws li deformations, nws zoo li lub tsheb kauj vab log nrog "daim duab yim". Qhov teeb meem yog qhov pom qhov sib txawv ntawm cov disk yuav tsis pom. Yog hais tias tom kawg yog qhov tsis zoo, ces overheating cuam tshuam nws heev detrimentally. Deformations yog muab rau nws, uas txhais tau hais tias kev co ntawm lub pedal thaum lub sij hawm braking yog yooj yim inevitable.

Deformations hauv nruas brakes

Nruas Nruas yog qhov ua tau zoo, tab sis qee zaum teeb meem tuaj yeem tshwm sim nrog lawv. Lawv, zoo li cov disks, tuaj yeem ua kom sov (tab sis tsawg dua). Overheating tshwm sim yog tias, ceev ceev, tus neeg tsav tsheb tsis nco qab tso lub tsheb ntawm lub tsheb nres thiab tib lub sijhawm taug kev deb txaus. Tus tsav tshebtej zaum yuav tsis txawm pom tias lub tsheb yog xyaum tsis txav. Thaum nres, tus brake tseem tsa, los yog tus brake twitches dua.

Los ntawm lub tsev kawm ntawv chav kawm ntawm physics nws paub tias thaum rhuab, cov hlau nyiam nthuav. Thaum nws txias, nws shrinks. Nyob rau hauv cov ntaub ntawv ntawm lub nruas nres, cov ntaub qhwv yuav tsis tso cai rau lub nruas rov qab mus rau nws li qub. Raws li qhov tshwm sim, cov duab geometry hloov pauv thiab siv daim duab ntawm lub ellipse. Yog li qhov kev vibration ntawm tus nres pedal thaum braking. Txhawm rau kom muaj kev nyab xeeb, lub tsheb nres system muaj ob lub voj voog sib luag lossis kab pheeb ces kaum. Nruas brakes niaj hnub no tsuas yog pom nyob rau hauv lub rear qag ntawm cov nyiaj txiag tsheb. Txawm li cas los xij, yog hais tias nyob rau hauv ib lub tsheb engineers tsim ib tug parallel circuit, ces ntaus ntawm lub pedals yuav hnov. Yog hais tias nws yog kab pheeb ces kaum, lub kauj tsheb vibrates thaum braking. Koj tuaj yeem txheeb xyuas lub nruas deformed lossis puas los ntawm qhov ci ntawm qhov chaw ua haujlwm. Nws yuav yog heterogeneous.

Brake cylinders

Lub tog raj kheej sab nraub qaum thiab pem hauv ntej yuav tsis ua haujlwm zoo. Feem ntau cov khoom ntawm lub nres nres tsuas yog tig qaub thiab tom qab ntawd poob. Qhov no ua rau lub pedal vibrate thaum braking. Kev daws qhov teeb meem no yooj yim heev - tsuas yog tshuaj tsuag WD-40 lossis cov roj zoo sib xws rau hauv cov txheej txheem no (ib qho analogue yog tsim los ntawm Mannol). Tab sis feem ntau tsuas yog hloov pauv xwb.

Hub ua rau muaj kev vibrations thaum braking

Qhov no yog qhov ua rau tsawg heev, tab sis koj yuav tsum tsis txhob txiav nws tawm. Feem ntau lub hub yog deformed tsuas yog nyob rau hauv ib qho kev huam yuaj los yog muaj zog heev cuam tshuam. Txawm li cas losthaum nws tsoo lub qhov, lub log feem ntau yuav tawm ntawm lub tsheb lossis kev co yuav tshwm sim ntawm lub kauj tsheb thaum tsav tsheb. Nws yuav tsis yog superfluous mus xyuas lub log bearing. Yog tias nws hnav tau pom, ces nws yog qhov laj thawj tseem ceeb rau cov tsos ntawm cov neeg ntaus. Rau kev kuaj mob, koj yuav tsum jack up lub tsheb (tso tawm lub log) thiab xyuas nws cov kev ua si - sway ntawm sab mus rau sab. Kev ua si yuav tsum tsawg, thiab kev sib hloov yuav tsum tsis muaj suab thiab hum.

Txoj haujlwm nres thiab pedal ntaus

Yog tias lub kaw lus nres tau ua haujlwm zoo, thiab qhov kev vibration thaum nres tseem hnov, thiab tib lub sijhawm nws tsis tuaj yeem pom cov khoom tsis zoo hauv txhua txoj kev, ces cov teeb meem tau muab zais rau hauv qhov chaw tsis tshua pom tseeb..

Nyob rau hauv cov xwm txheej zoo li no, cov kws tshaj lij qhia kom kuaj xyuas lub log sib npaug. Qhov tseeb yog tias thaum tsis sib npaug, lub zog centrifugal ua rau lub log. Nws yog tus ua rau txhua yam teeb meem. Tus neeg tsav tsheb uas paub txog tuaj yeem txheeb xyuas lub log tsis sib npaug. Tab sis nyob rau hauv cov ntaub ntawv no, lub vibrations yuav tsis tau tsuas yog nyob rau hauv lub pedals, tab sis thoob plaws hauv lub cev. Koj yuav tsum tau kuaj xyuas lub hauv ntej ncua kev kawm ntawv. Kev vibration nyob rau hauv tus nres pedal thaum braking tuaj yeem yog ib qho cim ntawm deformed suspension caj npab los yog xoob mountings.

Nws raug nquahu kom ua tib zoo xyuas qhov kev ntseeg siab ntawm lub cev nrawm, ncua kev kawm thiab nres qhov system. Cov chaw pabcuam feem ntau pom cov bolts tsis zoo thoob plaws hauv lub tsheb. Qhov teeb meem no yuav muaj teeb meem tshwj xeeb yog tias lub tsheb feem ntau siv rau ntawm txoj kev tsis zoo.

Nres Caliper

Ib yam ntxivIb qho laj thawj tsis tshua muaj kev vibration tshwm sim thaum braking yog lub zog tsis sib xws ntawm lub caliper. Yog li ntawd, nws jams. Tab sis nws yog ib qho nyuaj heev los txheeb xyuas qhov teeb meem ntawm koj tus kheej - koj yuav tsum tau mus ntsib qhov chaw pabcuam tshwj xeeb.

vibration thaum braking ntawm nrawm

Thaum lub tsheb tsav tsheb ntawm kev kub ceev, qhov chaw nres tsheb yuav raug cua sov. Nws yog qhov ua tau tias lub disc thiab caliper tau kub heev, jam, thiab vim li ntawd, ntawm qhov nrawm thaum braking, vibration lossis txawm muaj zog co.

Txoj kev phom sij: xoob log

Qhov no yog ib qho teeb meem kho tau yooj yim. Kev kuaj mob kuj yog ib qho yooj yim. Nws yog vim li no uas muaj ntau yam kev vibrations thiab ntaus feem ntau tshwm sim. Ib lossis txawm tag nrho plaub lub log yuav xoob.

Yuav yooj yim npaum li qhov laj thawj no, nws txaus ntshai heev. Yog tias qhov teeb meem tsis pom nyob rau lub sijhawm, qhov tshwm sim tuaj yeem ua rau muaj kev txaus ntshai heev tsis yog rau tus neeg tsav tsheb lossis nws cov neeg caij tsheb, tab sis kuj rau lwm tus neeg siv txoj kev. Kho hauv qhov no, uas yog, yog tias koj tsis pom cov neeg ntaus hauv lub sijhawm, tuaj yeem kim heev. Cov hub tau tawg, lub log disks yog deformed, nres discs yog deformed thiab lub mounting qhov ntawm lub disk yog tawg. Yog tias muaj kev vibration thaum lub sijhawm braking, nws yog qhov zoo dua rau ib zaug kom paub tseeb tias tag nrho cov bolts tau nruj nruj txaus. Tab sis koj yuav tsum tsis txhob rub nws mus rau tus cwj pwm squeak ib yam.

Dab tsi ua rau ntaus thiab vibration?

Cov laj thawj no tsis tshua muaj, tab sis tseem yuav tsum tau xav txog. Qee zaum ntsibCov teeb meem me me hauv lub kauj tsheb lossis pob pob qij txha ntawm lub tsheb hauv qab yog hnav dhau lawm.

Tsis tas li, kev vibrations thiab ntaus yuav tshwm sim vim hnav cov khoom poob siab. Tab sis nyob rau hauv cov ntaub ntawv no, cov nyhuv yuav hnov thaum lub sij hawm ntawm kev sib hloov. Tsis tas li ntawd, kev ntaus hauv lub tshuab nres thiab lub kauj tsheb tuaj yeem ua rau muaj kev cuam tshuam ntawm lub tsheb muaj zog.

Qhov teeb meem puas tuaj yeem tsis quav ntsej?

Yog tias kev vibration tshwm sim thaum nres (VAZ-2170 tsis muaj qhov tshwj xeeb), ces nws yog qhov zoo dua mus ntsib qhov chaw nres tsheb yam tsis muaj kev ncua. Tab sis koj tuaj yeem kaw koj lub qhov muag rau qhov teeb meem no rau ib lub sijhawm - qee cov neeg tsav tsheb zoo li no thoob plaws xyoo. Txawm li cas los xij, yog tias qhov laj thawj nyob hauv qhov tsis muaj zog nruj ntawm cov txiv ntoo ntawm lub log, ces qhov no yog qhov txaus ntshai heev. Xws li kev ntaus hauv lub kaw lus nres ua rau muaj qhov tseem ceeb ntawm lwm qhov hauv lub chassis.

Tsis tas li, kev vibration ntawm qhov nrawm, raws li tau hais tseg, tuaj yeem ua rau muaj kev sib tsoo - nws yooj yim heev kom tsis txhob tswj lub tsheb. Tsav tsheb yog qhov txaus ntshai ntawm nws tus kheej, thiab yog tias cov tsos mob tshwm sim, nws yog qhov zoo dua los nrhiav thiab tshem tawm qhov ua rau. Tsis txhob ua phem rau koj tus kheej thiab cov neeg caij tsheb. Khaws koj lub tsheb kom zoo - saib xyuas koj tus kheej thiab koj cov neeg koj hlub.
