Yog vim li cas lub gearbox nrov
Feem ntau, lub suab nrov hauv lub gearbox, ob qho tib si hauv phau ntawv thiab tsis siv neeg, tshwm thaum roj qib tau poob lawm los yog lub iav lubricant tsis siv tau lawm. Qhov xwm ntawm lub suab zoo ib yam li ib tug hlau clang, uas intensifies raws li lub ceev ntawm lub tsheb nce. Yog li, lub suab nrov hauv lub gearbox nrog qib roj qis tshwm:
ATF daim dipstick
- thaum lub tsheb txav ceev (qhov siab dua, lub suab nrov nrov);
- nyob rau hauv idle ceev ntawm lub internal combustion engine;
- thaum lub sij hawm acceleration (yuav tsum maj mam nce nyob rau hauv lub ntim ntawm hum);
- nyob rau hauv nruab nrab iav;
- thaum lub cav khiav txias.
Yog vim li cas rau lub rumble los ntawm lub gearbox thaum lub internal combustion engine yog khiav ntawm ib tug txias yuav tsum tau them. nyob rau hauv lub thickness ntawm iav roj thiab nws cov pa phem.
Lwm qhov laj thawj yog vim li cas lub gearbox yog buzzing yog ib feem tsis ua hauj lwm ntawm cov bearings ntawm thawj los yog theem nrab shafts. Nyob rau hauv cov ntaub ntawv no, lub suab yuav zoo li ib tug hlau hum. Thawj (tsav) ncej bearings yuav hum hauv cov xwm txheej hauv qab no:
- tam sim ntawd tom qab pib lub combustion engine nyob rau hauv ib tug txias;
- thaum lub combustion engine yog khiav ntawm tsawg speeds (thaum thawj, thib ob, lub hum txo);
- thaum tsav tsheb ntug hiav txwv;
- thaum lub cav khiav ntawm kev kub ceev.
Nyob rau hauv cov ntaub ntawv ntawm tsis ua hauj lwm ntawm cov bearings ntawm lub thib ob (tsav) ncej box hum yuav pom:
Bearing ntawm lub tswv yim ncej ntawm lub gearbox Vaz-2110
- thaum tsav tsheb hauv txhua hom;
- nyob rau hauv tsab ntawv tsa suab, txawm li cas los xij, thaum lub clutch nyuaj siab, lub hum ploj;
- lub hum nyob rau hauv lub thawv nce raws li lub iav thiab ceev nce (uas yog, lub hum yog tsawg heev nyob rau hauv thawj iav, thiab lub nrov tshaj plaws nyob rau hauv thib tsib).
Nrog rau qhov tseem ceeb ntawm cov iav los yog synchronizers, qhov xwm txheej kuj yuav tshwm sim thaum lub gearbox howls. Lub suab nyob rau tib lub sij hawm zoo li ib tug hlau clang, uas intensifies raws li lub cav ceev nce. Feem ntau, cov hum tshwm nyob rau hauv ib qho tshwj xeeb iav. Qhov no tsim teeb meem ntxiv:
- iav yog ib qho nyuaj rau tig ntawm phau ntawv kis tau tus mob;
- Nyob rau hauv cov lus tsa suab, qhov suav nrog ceev yuav "yav tawm", uas yog, lub iav selector yog teem rau qhov nruab nrab txoj hauj lwm.
Raws li kev sib kis tsis siv neeg, lawv cov hum kuj tuaj yeem tshwm sim vim kev coj tus kheej, cov roj tsawg, iav hnav. Txawm li cas los xij, hauv kev sib kis tsis siv neeg, lub hum tuaj yeem tshwm sim thaum nws ua tsis tiav:
- kev sib txhuam khub;
- tus kheej qhov chaw ntawm lub torque converter.
Dab tsi tuaj yeem yog lub suab nrov hauv lub gearbox
Lub suab nrov ntawm lub thawv tuaj yeem hnov txog qhov sib txawv, nyob ntawm qhov kev puas tsuaj, nws tsis yog tsuas yog ua haujlwm nrog lub suab nrov, tab sis kuj hawb pob lossis buzzes. Cia peb piav qhia luv luv ntawm cov laj thawj yog vim li cas cov nodes saum toj no ua rau qhov tseeb tias lub gearbox howls thiab buzzes. kom koj nkag siab tias yuav ua li cas nrog nws thiab yuav kho qhov teeb meem li cas.
Hwj chim gearbox
Feem ntau yog vim li cas rau lub suab nrov nyob rau hauv lub gearbox zoo li lub howl yog ib qho qub, qias neeg los yog tsis raug xaiv kis roj. Yog tias nws qib tsis txaus, yog li qhov tshwm sim ntawm qhov no, cov bearings thiab lwm qhov txav ntawm lub thawv yuav khiav qhuav, ua suab nrov. Qhov no tsis yog tsuas yog tsis xis nyob thaum tsav tsheb, tab sis kuj muaj teeb meem rau qhov chaw. Yog li ntawd, nws yog ib txwm tsim nyog los tswj cov roj theem nyob rau hauv lub gearbox thiab nws viscosity.
Qhov thib ob yog vim li cas lub gearbox howls yog nyob rau hauv hnav ntawm nws bearings. Lawv tuaj yeem quaj vim qhov hnav tsis zoo, tsis zoo, cov roj nplua nyeem me me hauv lawv, lossis cov av uas tau nkag mus rau hauv.
Yog hais tias lub thawv tsis muaj suab nrov thaum tsis ua haujlwm nrog lub clutch tso tawm, nyob rau hauv nruab nrab iav thiab thaum lub tsheb nyob twj ywm, ces feem ntau yuav cov kabmob ntawm lub hauv paus ncej yog nrov. Yog tias lub thawv buzzes ntau dua hauv thawj lossis thib ob iav, ces hnyav load mus rau pem hauv ntej bearings. Yog li ntawd, nws yog ib qho tsim nyog yuav tau kuaj xyuas qhov input ncej bearing.
Ib yam li ntawd, cov tswv yim ncej bearing tuaj yeem ua suab nrov thaum lub tsheb yog coasting lossis tsuas yog tom qab pib lub cav combustion, txawm tias qhov ceev npaum li cas. Feem ntau cov suab nrov ploj hauv qhov no thaum lub clutch nyuaj siab. Yog vim li cas rau qhov no yog tias thaum lub clutch nyuaj siab, lub hauv paus tsis tig, cov kabmob kuj tsis tig, thiab, raws li, tsis ua suab nrov.
Hnav gearbox iav
Yog tias lub thawv nrov nrov hauv 4th lossis 5th iav, ces qhov no hnyav load mus rau lub rear bearings, uas yog, qhov thib ob ncej. Cov kabmob no tuaj yeem ua suab nrov tsis yog nyob rau hauv lub zog siab, tab sis kuj nyob rau hauv ib qho twg, nrog rau kev thim rov qab. Ntxiv mus, lub hum intensifies nyob rau hauv cov ntaub ntawv no nrog ib tug nce nyob rau hauv lub zog (nyob rau hauv lub thib tsib hum nws yuav siab tshaj plaws).
iav hnav - Qhov no yog qhov thib peb vim li cas lub thawv quaj. Cov suab nrov zoo li no tshwm sim nyob rau hauv ob qhov xwm txheej: plam ntawm cov hniav thiab ib qho kev sib cuag tsis raug ntawm lawv. Lub suab no txawv ntawm lub suab nrov, nws zoo ib yam li cov hlau nplaum. Qhov no squeal kuj tshwm sim nyob rau hauv load los yog thaum lub sij hawm acceleration.
Feem ntau qhov ua rau lub suab nrov yog qhov tseeb ntawm lub iav thaum lub suab tshwm ntawm ib qho tshwj xeeb iav. Lub gearbox ua suab nrov thaum tsav tsheb ntawm kev ceev vim yog banal hnav ntawm cov iav sib thooj ntawm cov ncej thib ob. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau cov gearboxes nrog cov mileage siab (los ntawm 300 txhiab kilometers lossis ntau dua) vim yog cov hlau tseem ceeb thiab / lossis cov roj qis hauv lub thawv.
Howling box tshuab
Nyob rau hauv ib tug tsis siv neeg kis tau tus mob, "culprit" ntawm howling yuav ua tau torque converter. Cov pob caus no yog hu ua "donut" vim nws cov duab. Torque converter hums thaum hloov lub zog thiab nyob rau hauv qis speeds. Raws li kev tsav tsheb nrawm, lub suab nrov ploj (tom qab li 60 km / h). Cov cim qhia ntxiv kuj qhia txog kev tawg ntawm "donut":
- tsheb slippage thaum pib;
- kev vibration ntawm lub tsheb thaum tsav tsheb;
- tsheb jerks thaum lub sij hawm tsis sib xws;
- cov tsos ntawm ib tug burnt tsw los ntawm tsis siv neeg kis;
- cov kiv puag ncig tsis nce siab dua qee qhov txiaj ntsig (piv txwv li, siab dua 2000 rpm).
Nyob rau hauv lem, breakdowns ntawm lub torque converter tshwm rau cov hauv qab no yog vim li cas:
Torque converter nrog tsis siv neeg kis
- hnav ntawm ib tus neeg sib txhuam discs, feem ntau yog ib lossis ntau dua ntawm lawv cov khub;
- hnav lossis puas rau cov hniav;
