Lub tsheb siv ntau yam kev qhia. Ib qho ntawm cov no yog lub log bearing. UAZ kuj tau nruab nrog lawv. Nws yog ib feem tseem ceeb ntawm txhua lub tsheb. Tom qab tag nrho, nws yog cov kabmob no uas ua kom muaj kev sib hloov ntawm kev tsav tsheb thiab tsav lub log nyob ib ncig ntawm lub axis. Cov node yog nyob rau hauv enormous load. Yog li ntawd, nws muaj peev xwm hais tias UAZ pem hauv ntej hub bearing yuav poob sib nrug. Cov peev txheej ntawm cov khoom no yog dab tsi, cov cim qhia ntawm kev ua tsis tiav thiab yuav hloov li cas? Tag nrho cov no - tom qab hauv peb tsab xov xwm.

Resource

Nyob rau nruab nrab, lub neej kev pab cuam ntawm lub caij no yog kwv yees li 150 txhiab kilometers.

Tab sis nws tsim nyog sau cia tias daim duab no yuav txawv heev. Ntawm ib lub tsheb UAZ Patriot, lub hub bearing tuaj yeem mus txog 300 txhiab, thiab ntawm lwm qhov nws tuaj yeem poob sib nrug los ntawm 40.

Vim li castshwm sim?

Kev puas tsuaj ntawm cov kabmob tshwm sim feem ntau vim tsis muaj lubrication. Nws tuaj yeem raug ntxuav tawm ntawm lub tawb. Qhov no tshwm sim tshwj xeeb tshaj yog rau cov tsheb uas siv nyob rau hauv off-road. Thaum hla lub ford tom ntej, dej nkag tsis tau tsuas yog cov choj thiab lub thawv, tab sis kuj UAZ hub bearing. Yog li ntawd, lub caij ua haujlwm "qhuav". Tsis tas li ntawd, UAZ hub bearing ua tsis tiav nyob rau hauv lub xub ntiag ntawm cov khoom paug. Plua plav thiab av yuav ua haujlwm zoo li abrasive hauv qhov clip. Kev thauj khoom siab kuj yog qhov ua rau tsis ua haujlwm ntawm lub log bearing. Yog tias lub tshuab feem ntau siv rau ntawm qhov chaw ntxhib, npaj rau qhov kev hloov pauv uas yuav los tom ntej. Tsis tas li ntawd, lub caij tsis nyiam cov pits loj. Txawm tias nyob rau ntawm txoj kev tsheb loj, tag nrho cov pob yuav tsum tau ua tib zoo saib xyuas. Lub hub bearing tsis nyiam tsav sloppy. Tsis tas li ntawd, kev poob siab raug xa mus rau lwm cov khoom raug tshem tawm. Cov no yog shock absorbers thiab ntsiag to blocks ntawm levers (nyob rau hauv rooj plaub ntawm Patriot pem hauv ntej ncua kev kawm ntawv).

Nyob tsis tshua muaj, qhov ua rau tawg yog lub Hoobkas ua haujlwm tsis zoo. Tias yog vim li cas UAZ hub bearing (tus naj npawb 127509 hauv phau ntawv teev npe) poob sib nrug los ntawm 30 txhiab, txawm hais tias nws muaj cov peev txheej sib txawv.

Kev teeb tsa kom raug yog tus yuam sij rau cov peev txheej siab

Kuv yuav ua li cas yog tias lub caij tsis rov qab hloov? Thiab tsis yog tom qab 30, tab sis 3 txhiab kilometers? Nws yog txhua yam hais txog qhov tsis ncaj ncees lawm installation. Qhov no yog ib qho ntawm cov laj thawj vim li cas lub log bearings poob. Yog tias koj nruab lub caij ntawm lub kaum sab xis tsis ncaj ncees lawm (obliquely), ces lub loadib clip yuav nce ntau zaus. Nyob rau hauv rooj plaub no, ib feem yuav vau twb nyob rau hauv thawj txhiab kilometers.

Lwm qhov tseem ceeb yog lub zog nruj. Yog hais tias, thaum hloov, tus tswv tau nruj lub bearing txiv ntseej, lub loads ntawm nws kuj yuav nce ntau zaus. Ib feem yuav kub txhua lub sijhawm. Yog li ntawd, UAZ yuav tsum tau hloov lub hub bearing dua.

Yuav txiav txim siab hnav li cas?

Txij li lub caij no cuam tshuam nrog lub hub, qhov kev ua tsis tiav yuav cuam tshuam nrog lub log. Kev txiav txim siab txog qhov tsis ua haujlwm yog qhov yooj yim heev. Ntawm qhov kev txav mus los, koj yuav hnov "qhuav crunch" (qhov no yog li cas cov txheej txheem kheej kheej yob). Qhov no txhais tau hais tias cov haiv neeg sab hauv yog tawg thiab cov koob spin unevenly. Lub suab no yuav muaj zog dua lub sijhawm.

Tsis tas li ntawd, kev ua haujlwm tsis zoo yuav ua rau muaj kev vibrations. Lawv tuaj yeem kis tau mus rau lub kauj tsheb thiab mus rau lub cev nws tus kheej. Tsav tsheb zoo li no yog qhov txaus ntshai heev, vim tias muaj kev pheej hmoo ntawm lub log wedge. Thaum muaj kev kub ceev, qhov no tuaj yeem ua rau tsis muaj kev tswj xyuas.

Yog koj tseem tsis quav ntsej qhov teeb meem, lub tsheb yuav pib rub mus rau ib qho kev taw qhia. Koj yuav tsum tau nqa lub kauj tsheb mus tas li kom ncaj nraim mus tom ntej.

Yuav hloov li cas? Tshem lub hub

Hmoov zoo, kev tsim ntawm Ulyanovsk-ua SUVs yog qhov yooj yim heev. Yog li ntawd, koj tuaj yeem hloov UAZ rear hub bearing nrog koj tus kheej txhais tes. Cia wb mus ua haujlwm.

Ua ntej, peb yuav tsum tau jack li ib feem ntawm lub tsheb, yav tas los torn tawmlog bolts. Lub tsheb muab tso rau ntawm lub tes tuav. Tsis tas li ntawd, nws raug nquahu kom nruab lub log chocks. Txhawm rau tshem tawm cov kabmob, koj yuav tsum tshem tawm tag nrho lub hub. Ua ntej, tshem lub brake disc. Tom ntej no, unscrew peb kho screws uas mus rau lub hau ntawm lub log tawm clutch. Peb tshem tawm cov ntsiab lus no thiab tig tawm rau lub bolts ntawm lub coupling nws tus kheej. Nyob rau hauv rooj plaub no, koj yuav tsum tau kho lub hub nrog ib tug mounting spatula. Txwv tsis pub, nws yuav scroll thaum lub sij hawm dismantling ntawm cov khoom. Tom qab tshem lub coupling, peb khoov lub tab ntawm lub xauv lub tshuab ntxhua khaub ncaws thiab unscrew lub ntsuas phoo ntawm lub hub nws tus kheej. Tom ntej no, tshem tawm lub tshuab ntxhua khaub ncaws nrog ib tug minus screwdriver. Unscrew lub hub txiv ntoo thiab lub hub sib dhos nws tus kheej.

Kev hloov pauv cov kabmob

Yog li, lub hub yog nyob rau hauv tes - nws tseem tsuas yog tshem tawm cov khoom qub thiab nruab ib lub tshiab. Txhawm rau ua qhov no, peb muab lub hau ntswj ntawm peb txhais tes thiab tshem tawm lub nplhaib puab ntawm lub hub. Cov ntsiab lus kawg kuj raug coj tawm. Thov nco ntsoov tias txhawm rau rhuav lub caij, koj yuav tsum tshem tawm cov qog. Nws yog pov tseg thiab tsis tuaj yeem rov nruab. Nyob rau theem tom ntej, peb tshem lub tshuab ntxhua khaub ncaws ntawm lub hub foob thiab unscrew lub puab bearing nplhaib.

Tag nrho cov ntsiab lus tshem tawm yuav tsum tau degreased - koj tuaj yeem siv roj av lossis nqus cov khoom hauv kerosene. Thaum txhim kho lub hub tshiab ntawm lub UAZ, xyuam xim rau cov xwm txheej ntawm cov khoom sib txuas nrog nws. Lub xub ntiag ntawm cov poholes, khawb thiab lwm yam cim ntawm kev hnav yog tsis tsim nyog. Thaum hloov, ob lub log sab hauv thiab sab nraud yog hloov.

Txhawm rau extrude ib qho qub, koj yuav tsumsiv lub ruber. Maj mam nyem lub kav hlau txais xov ntawm lub nplhaib sab hauv thiab sab nraud thiab rub cov khoom tawm.

Installation

Nws tsis raug tso cai rau nruab lub caij nrog rauj lossis lwm yam improvised. Txhawm rau kom tsis txhob cuam tshuam, siv lub mandrel. Peb yuav nias rau hauv cov kabmob tshiab nrog nws. Tom qab kev txhim kho tiav, qhov zoo ntawm qhov haum ntawm lub caij yuav tsum tau rov kuaj dua. Cov kabmob rings yuav tsum tsis txhob tig los ntawm tes. Kev sib dhos ntxiv yog ua nyob rau hauv qhov kev txiav txim rov qab.

ntsiab lus tseem ceeb: saib cov kabmob zawm torque. Cov txiv ntseej hloov yuav tsum nruj nrog lub zog ntawm 30 txog 40 Nm. Tig lub log ntawm lub tsheb jacked los ntawm tes - nws yuav tsum tig tau yooj yim. Nyob rau hauv cov ntaub ntawv no, ib tug me me backlash yog tso cai. Nws tsis yog qhov tsim nyog los zawm cov txiv ntoo kho txhua txoj hauv kev - yuav tsum muaj cov thermal clearance rau cov kabmob.

Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws

Ua ntej txhim kho cov kabmob, xyuas qhov zoo ntawm lubrication ntawm "koob". Feem ntau manufacturers tsis qhia lubrication. Vim li no, cov peev txheej poob qis heev. Raws li rau hom roj nplua nyeem, koj yuav tsum tau siv tsuas yog tshwj xeeb - rau lub log bearings. Ib txwm "Litol" lossis "graphite" yuav tsis ua haujlwm.

Zoo kawg

Yog li, peb pom yuav ua li cas hloov lub hub bearing ntawm lub tsheb UAZ ntawm peb tus kheej thiab nws cov tsos mob ntawm kev ua haujlwm tsis zoo yog dab tsi. Txhawm rau tshem tawm kev hnav ntxov ntxov, nws tsim nyog muab cov koob lub ntsiab nrog cov roj nplaum zoo thiab tshem tawm cov kev cuam tshuam thaum lub sijhawm teeb tsa.
