Dab tsi yog ntsiag to thaiv thiab thaum twg nws yog hloov

Silent blocks (tom qab no hu ua "s / b") yog ib feem ntawm kev ncua, uas yog ob lub hlau bushings, ntawm qhov uas muaj cov roj hmab ntxig. Lub kaw lus ntsiag to txuas cov khoom ncua kev kawm rau ib leeg, dampens vibrations ntawm cov nodes. Cov blocks uas ntsiag to pab txhawb rau kev caij tsheb zoo vim qhov elasticity ntawm cov roj hmab, uas ua haujlwm raws li lub damper ntawm qhov raug ncua. 

Dab tsi yog ntsiag to thaiv thiab nws lub hom phiaj

Cov tshuab ntsiag to ua haujlwm kom tsis txhob deformation ntawm qhov kev ncua thiab lub cev ua haujlwm. Lawv yog thawj tus coj tawm cov kev poob siab thiab kev tshee, tom qab ntawd lawv tau xaum los ntawm kev nqus tau. Tsis tas li ntawd cov twj ywm uas ntsiag to tau muab faib ua cov pawg hauv qab no:

• kev tsim kho (nrog rau ib qho, ob lub roob lossis tsis muaj hlau ntsiab);
• kev tsim qauv (khoom tawg yooj yim lossis nrog lub qhov);
• hom kev txuas (bushings lossis tsev nyob nrog cov kab nraj);
• kev mus ncig (nruab nrab ntawm tes thiab "ntab");
• cov khoom siv (roj hmab lossis polyurethane).

Structurely, ntsiag to blocks txawv nyob rau hauv cov duab, nyob ntawm seb tus tsim ntawm lub lever. Feem ntau, ob lub bushings yog siv rau ntawm daim duab peb sab levers ntawm MacPherson hom pem hauv ntej ncua kev kawm ntawv - rear ntsiag to blocks nrog ob bushings, pem hauv ntej sawv daws yuav nrog ib tug puab ntsia liaj qhov rooj, tsis muaj txheej txheem. Los ntawm txoj kev, lub rear s / b ntawm lub hauv ntej ncua kev kawm ntawv yuav tsum tau hydrofilled. Qhov kev tsim no tso cai rau koj kom zoo dua nqus lub zog vibration, tab sis sai li sai tau thaum cov kua pib ntws tawm, qhov ua tau zoo ntawm cov blocks ntsiag to txo ​​qis.

Raws li cov qauv siv khoom, nws yog qhov zoo dua los siv cov khoom s / b, lawv cov peev txheej tau ntau dua.

Hais txog kev txav mus los, "floating" blocks ntsiag to yog tsim nyog tshwj xeeb. Lawv yog siv nyob rau hauv lub rear multi-txuas ncua kev kawm ntawv, lawv yuav tsum tau nias rau hauv lub steering knuckle los yog transverse pas nrig. Lub hub "floating" muaj ib txoj hauj lwm thib ob - kom lub log tig ywj siab ntawm ib lub kaum ntse ntse, thaum tseem tsis tau txav mus rau hauv lub dav hlau ntsug thiab kab rov tav. Cov khoom yog ib lub tawb, kaw rau ob sab nrog anther, nyob rau hauv uas lub pob khawm yog ntsia.Vim lub zog ntawm lub pob khawm, lub rear ncua kev kawm ntawv "steers" thaum tsim nyog, lub tsheb nyob rau hauv txoj kev yog ruaj khov nyob rau hauv lub ntse lem. rau qhov no .. Lub ntsiab tsis zoo ntawm "floating" bushing yog tias cov roj hmab khau looj plab hlaub yog qhov yooj yim heev rau ib puag ncig hnyav, tom qab ntawd nws dhau los ntawm plua plav thiab noo noo, txo qis lub neej ntawm ib feem. 

Cov twj uas ntsiag to nyob qhov twg?

Roj hmab-hlau bushings siv nyob rau hauv cov ntu raug tshem tawm hauv qab no:

• pem hauv ntej thiab nram qab lub teeb;
• txoj kab txuas ntev thiab transverse ntawm qhov txuas tom qab;
• raws li stabilizer bushings;
• hauv kauj tawv;
• hauv kev poob siab absorber;
• raws li mount rau lub hwj chim ntim thiab kis;
• ntawm subframes.

Kev siv tag nrho ntawm cov tshuab ntsiag to tsis txhob siv cov roj hmab Bushings tau txhim kho tus yam ntxwv kev ntawm lub tsheb nqaj hlau qis vim tias cov roj hmab hauv lub rooj sib tw ua haujlwm zoo dua rau kev sib ntswg, dampens kev ua kom zoo dua thiab tsis hnav kom nrawm dua. 

Hom thiab hom kev thaiv ntsiag to

Muaj ob pawg los ntawm qhov uas txhua daim uas ntsiag to tau txwv:

• Los ntawm cov khoom siv uas lawv tau ua;
• Los ntawm hom (hom thiab tsim).

Lub bushings ntawm lub nqaj qaum thiab pem hauv ntej tswj caj npab yog ua los ntawm roj hmab lossis polyurethane.

Los ntawm hom lawv txawv:

• Txuj tsis-caij. Cov ntu ntawd muaj lub tawb hlau nrog cov roj hmab ntxig rau hauv. Kuj tseem muaj kev hloov kho nrog ib tus ntxig hlau. Hauv qhov no, nws yuav muab tso rau sab hauv roj hmab hauv paus.
• Perforated ntsiag to thaiv lossis nrog cov kab noj hniav hauv ntu roj hmab. Xws li cov ntsuas ntsiag to muab kev sib hloov du ntawm kev sib zog. Qhov ntu yuav tsum tau nias hauv tusyees kom lub nra xa tawm tag nrho cov ntu ua haujlwm.
• Ntsiag to thaiv nrog asymmetric lugs. Cov seem tsis muaj qhov dhau ntawm lub qhov. Eyelets yog siv hloov. Txoj kev tsim qauv no tso cai rau koj los kho cov khoom uas muaj nyob hauv cov phiaj me chaw ua haujlwm sib ze.
• Ntab tsim. Sab nraud, cov nplais ntsiag to cov ntsiab lus zoo ib yam li pob bearings. Yog li hais tias thaum lub sijhawm ua haujlwm lub roj hmab tsis hnav, nws yog npog nrog cov roj hmab khau raj. Txoj kev hloov kho no muab kev txav mus los ntawm ntu ntu ntawm nws. Lawv tuaj yeem siv rau kev qib siab, tab sis ntau zaus lawv tau nruab rau hauv cov kauj ntoo ntawm lub hub.

Yuav kuaj xyuas cov ntawv nyob ntsiag to li cas?

Qhov nruab nrab cov peev txheej ntawm cov khoom siv roj hmab-hlau raug tshem tawm yog 100 km. S/b diagnostics yog ua txhua txhua 000 km. Ua li no, koj yuav tsum tau tsa lub tsheb ntawm lub nqa. Thawj qhov kev tshuaj xyuas yog pom, nws yuav tsum tau txheeb xyuas qhov muaj cov kab nrib pleb lossis ruptures ntawm roj hmab. Yog tias muaj cov kab nrib pleb, qhov no yog lub cim qhia tias s / b yuav tsum tau hloov sai sai.

Ntxiv mus, daim tshev yog nqa tawm siv mount. Kev qev tiv thaiv kev tiv thaiv kev qev, peb qog nws txoj haujlwm, thaum txoj hlab ntaws hlab ntuag yuav tsum nruj. Qhov no kuj siv rau kev cav cav, lub cav poob siab.

Ntawm kev mus, lub khob muaj zog ntawm kev tsis meej, "laxity" ntawm kev ncua ntawv hais txog kev hnav ntawm lub twj ywm.

Thaum pauv

Kev hloov pauv ntawm cov ntawv nyob ntsiag to tsuas yog tsim nrog pom tseeb hnav, nyob rau hauv lwm yam nws ua rau tsis muaj peev xwm kov lawv. Nws raug nquahu kom hloov cov roj hmab-hlau ntu ntawm ob sab, vim tias thaum mus, kev ncua yuav tsum pib ua kom pom nws tus kheej tsis txaus vim muaj qhov sib txawv hauv kev ua haujlwm ntawm lub levers. 

Los ntawm txoj kev, tsis yog txhua qhov kev ncua pib "suab" thaum s / w hnav. Piv txwv li: lub tsheb Mercedes-Benz W210 thiab BMW 7-series E38 nyob twj ywm "ntsiag to" mus txog qhov kawg, txawm tias thaum lub suab ntsiag to tawg tag. Qhov no qhia tias kev siv lub iav yuav tsum raug tshuaj xyuas raws li kev mus ncig thiab thawj cov cim ntawm kev coj tus cwj pwm tsis zoo.

Lub Neej Txom Nyem

Feem ntau, cov peev txheej ntawm cov khoom qub dhau mus txog 100 km lossis ntau dua, nyob ntawm seb lub tsheb ua haujlwm qhov twg. Kev hais lus ntawm analogues, cov kev xaiv pheej yig tshaj plaws yuav ua twb poob lawm ntawm ob txhiab kis lus mev. Cov mais ntu ntawm qhov zoo ib qho piv tau yog 000-50% ntawm cov peev txheej ntawm cov khoom qub. 

Yuav ua li cas hloov cov blocks ntsiag to kom raug

Qhov nyuaj ntawm cov txheej txheem los hloov cov blocks ntsiag to nyob ntawm tus qauv ntawm lub tsheb, ntau qhov tseeb ntawm hom kev ncua ntawm lub tsheb. Tab sis txawm nyob rau hauv cov qauv yooj yim tshaj plaws, cov blocks ntsiag to tsis yog ib txwm yooj yim los hloov.

Nov yog cov lus qhia ib kauj ruam rau ib ntus ntawm txoj haujlwm no:

1. Xaiv cov cuab yeej tsim nyog. Txhawm rau dai lub tsheb, koj yuav xav tau lub jack (yog tias nws tseem tsis tau nyob hauv cov cuab yeej tsav tsheb, ces nyob rau hauv ib kem tshooj paub meej yuav ua li cas xaiv nws rau koj lub tsheb). Koj tseem yuav xav tau cov txheej txheem wrenches. Txhawm rau ua kom yooj yim rau kev teeb tsa cov blocks ntsiag to, nws yog qhov zoo dua los yuav ib lub cuab yeej rau nias rau hauv khw. Tsis tas li ntawd, koj yuav xav tau ib tug tshwj xeeb ruber rau pob bearings.
2. Tsa ib sab ntawm lub tsheb thiab tshem tawm lub log uas raug tshem tawm.
3. Unscrew thiab tshem tawm cov txiv ntoo saum lub pob sib koom ua ke.
4. Lub caj npab suspension yog unscrewed.
5. Lub block uas ntsiag to yog nias tawm thiab ib qho tshiab yog nias rau hauv.
6. Lub lever yog mounted. Lubrication yog ntxiv kom qhov sib koom ua ke tsis hnav sai dua.
7. Cov txheej txheem tib yam yog ua nrog rau sab caj npab.
8. Lub log yog baited thiab nruj twb nyob rau hauv av.

Yog hais tias nyob rau hauv lub tsheb lub rear ib feem ntawm lub ncua kev kawm ntawv yog nruab nrog ntsiag to blocks, ces lawv yuav tsum tau hloov nyob rau hauv ib tug zoo sib xws:

• Lub tsheb nram qab yog dai tawm.
• Cov xwm txheej ntawm cov blocks uas ntsiag to thiab muaj kev ua si hauv cov levers raug kuaj xyuas.
• Cov blocks ntsiag to tom qab raug hloov yog tias muaj cov backlashes hauv cov levers lossis cov roj hmab ntawm cov khoom kom meej meej hnav tawm (muaj deformations lossis tawg).

Txwv tsis pub, cov blocks ntsiag to ntawm lub qag nram qab tau hloov pauv zoo ib yam li hauv pem hauv ntej. Cov log yog clamped thaum lub tshuab twb nyob rau hauv av los tiv thaiv lub tsheb los ntawm slipping ntawm lub jack.

Thaum hloov cov blocks uas ntsiag to, qhov ncua sij hawm geometry yog ib txwm ua txhaum, txij li cov levers thiab pob bearings yog unscrewed. Vim li no, tom qab ua haujlwm kho, nws yog ib qho tsim nyog yuav tau kho qhov kev sib tw. nws yog qhov tseem ceeb ntawm cov txheej txheem no tau piav qhia meej.

Qhov kev kaw ntsiag to twg zoo dua: polyurethane lossis roj hmab?

Qhov tseeb, yog tias lub suab tsis sib haum, qhov tsim nyog yuav hloov nws nrog qhov zoo ib yam, uas tau muab los ntawm cov neeg tsim khoom. Yog hais tias tus tsav tsheb tsis paub nrog lub cuab yeej ntawm nws lub tsheb, ces kev xaiv ntawm lub ntsiag to tuaj yeem nqa tawm raws li phau ntawv teev npe rau ib lub tsheb tshwj xeeb.

Ua ntej hloov cov twj ywm uas tsis muaj ntsiag to, tus tswv tsheb yuav tsum txiav txim siab ntawm cov khoom siv los ntawm qhov twg ua.

Hauv kev lag luam pib tsheb niaj hnub, tus neeg yuav khoom tau muab ob txoj kev xaiv: roj hmab thiab polyurethane analogues. Ntawm no yog qhov sib txawv.

Roj hmab uas ntsiag to thaiv

Hauv plawv ntawm cov ntawv uas ntsiag to yog cov roj hmab. Cov khoom no pheej yig thiab yooj yim mus nrhiav hauv khw muag khoom. Tab sis qhov kev xaiv no muaj ob peb yam tsis zoo:

• Cov peev txheej ua haujlwm me me;
• Tsim, txawm tias tom qab hloov;
• Lawv tsis zam lub zog kev cuam tshuam ib puag ncig, piv txwv li, cov roj hmab tawg hauv qab ntim hauv cov te hnyav.

Polyurethane tshuab ntsiag to

Qhov teeb meem tshwj xeeb tshaj plaws ntawm polyurethane ntsiag to cov khoom sib piv piv rau yav dhau los yog qhov nqi siab. Txawm li cas los xij, qhov kev xav tau dhau los ntawm qhov muaj ntau qhov zoo:

• Cov haujlwm ntsiag to;
• Lub tsheb tus cwj pwm ntawm txoj kev ua softer;
• Lub fulcrum tsis yog ntau heev deformed;
• Kev ua haujlwm nce hauv lub neej (qee zaum txog 5 zaug thaum piv nrog cov roj hmab roj hmab);
• Nws dampens kev co zoo dua;
• Txhim kho qhov kev tsav tsheb.

Vim li cas tsis ua hauj lwm thiab dab tsi tawg rau hauv lub tsev ntsiag to

Yeej, peev txheej ntawm txhua lub tsheb muaj feem cuam tshuam tsis tsuas yog nws cov khoom zoo, tab sis kuj los ntawm kev ua haujlwm. Nws thiaj li tshwm sim hais tias qhov zoo-thaiv ntsiag to kev txiav txim siab tsis ua rau nws cov khoom siv hauv lub tsheb uas niaj zaus tsav ntawm txoj kev tsis zoo.

Hauv lwm qhov xwm txheej, lub tsheb raug ua haujlwm mus rau txoj hauv kev hauv nroog ntau dua, thiab tus tsav tsheb tau tsav tsheb kom raug thiab ntsuas tau. Hauv cov xwm txheej zoo li no, txawm tias ib daim phiaj siv nyiaj ntsiag to tuaj yeem ua rau cov khoom tsis zoo.

Lub ntsiab ntawm cov ntu ntsiag to yog tawg los yog deformation ntawm cov roj hmab ib qho, vim tias nws yog damper rau lub dawscrum. Sib ntswg yuam ua rau nws ntawm qee cov ntshav. Qhov sib tsoo ntawm cov hlau ntu yog qhov tsawg kawg. Lub ntsiab tseem ceeb rau qhov no yog kev ua txhaum ntawm tus txheej txheem nias.

Roj hmab tshooj tawm ua ntej yug nyob rau hauv cov teeb meem hauv qab no:

• Kev ua txhaum lub thev naus laus zis los hloov cov ntsiag to. Thaum lub pob zeb thaiv kev sib tw nruj, lub tsheb yuav tsum khov kho ntawm nws lub log thiab tsis nres. Txwv tsis pub, ib feem ntu tsis raug txuas ntxiv yuav nrawm tom qab lub tshuab tau qis mus rau hauv av. Tom qab, cov roj hmab yuav tawg hauv qab kev thauj khoom ntxiv.
• Kev ua txhaum ntawm cov nias txheej txheem. Yog hais tias qhov ntu nruab nrog kev txiav txim siab, thaum lub sijhawm ua haujlwm thauj khoom yuav tsis faib tusyees.
• Ntuj coj thiab rhuav. Qee cov neeg tsav tsheb tau them nyiaj rau ntsiag to cov khoom nyob ntsiag to tsuas yog thaum muaj teeb meem nrog lawv, feem ntau tshaj qhov xav tau kev pab lub neej.
• Raug tshuaj lom ntau dhau. Qhov no yog lub laj thawj rau cov reagents uas tau nchuav rau ntawm txoj kev. Cov roj cav zoo tib yam tseem yuav tsoo roj hmab nrog yooj yim.

Ntawm no yog cov phiajcim koj tuaj yeem txiav txim siab tias cov ntsiag to uas yuav tsum tau hloov:

• Lub tsheb tsav yuav luag 100 mais (yog tias txoj kev tsheb tsis zoo, tom qab ntawd lub sij hawm hloov qis dua - tom qab kwv yees li 000-50 txhiab);
• Backlash zoo nkaus li, lub tsheb nres tsis ruaj khov thiab tsis xis tsav;
• Tus qauv qaij ntawm cov log tsheb coj tawm tsis sib xws (nws yuav tsum tau ris hauv siab tias qhov no tuaj yeem yog lwm qhov kev ua tsis zoo, uas tau piav qhia hauv cais cov lus);
• Qib mountings puas.

Nqa cov pa kom ncav sijhawm thiab ua tau zoo tu lub tsheb, tus tswv ntawm lub tsheb yuav zam kev pov tseg tsis tsim nyog ntawm kev kho qhov chaw uas tseem tsis tau tuaj txog.
