Thaum hloov cov shock absorber struts
Txheem
Thaum tsav tsheb, kev ncua ntawm lub tsheb yog raug rau cov khoom hnyav heev. Tshwj xeeb tshaj yog qhov no yog yooj yim los ntawm ib tug ntse tsav style. Thiab ntawm peb txoj kev sib tsoo, cov khoom thauj feem ntau muaj qhov ua rau poob siab.
Txhawm rau txo cov loads thiab dampen qhov tshwm sim kev vibrations, ncua kev kawm ntawv struts yog ntsia rau hauv tsheb. Tsis tsuas yog caij kev nplij siab, tab sis kuj muaj kev nyab xeeb nyob ntawm qhov zoo ntawm kev ua haujlwm thiab qhov xwm txheej ntawm cov racks.
Hnav shock absorbers tuaj yeem ua tsis tau thaum lub sijhawm tsis zoo tshaj plaws, piv txwv li, thaum lub sijhawm ua haujlwm hnyav lossis tig ntawm kev kub ceev. Qhov no yog tshwj xeeb tshaj yog muaj tseeb rau pem hauv ntej ncua kev kawm ntawv struts ntawm pem hauv ntej-log tsav tsheb.
Khib thiab shock absorber. Qhov txawv yog dab tsi
Ntau tus neeg tsav tsheb tsis tshua nkag siab tias lub shock absorber yog dab tsi thiab nws txawv li cas ntawm lub shock absorber. Cov neeg muag khoom feem ntau ua rau muaj qhov tsis meej pem los ntawm kev lees paub cov neeg yuav khoom tias lawv yog ib qho thiab tib yam.
Ib qho kev poob siab absorber yog ib lub tog raj kheej nrog lub piston ntawm tus pas nrig. Lub tog raj kheej yog ntim nrog cov kua nplaum los yog roj. Nrog rau txoj kab ntsug ntawm qhov kev ncua, lub piston nias ntawm cov kua thiab nws maj mam ntws mus rau lwm qhov ntawm lub tog raj kheej los ntawm qhov me me hauv lub piston. Nyob rau hauv ntxaib-tube shock absorbers, muaj lwm qhov ib ncig ntawm lub tog raj kheej ua haujlwm.
Nyob rau hauv no embodiment, cov kua (los yog roj) raug yuam los ntawm lub valve rau hauv lub tog raj kheej thib ob. Qhov no tsuas yog ua haujlwm hauv compression thiab muaj peev xwm noj cov khoom tseem ceeb hauv kev coj ntawm nws axis.
Yog hais tias lub shock absorber yog hnav, braking kev ua tau zoo txo, log tsheb hnav sai dua, lub tsheb sways thiab bounces, thiab tsav tsheb yuav nkees heev rau tus neeg tsav tsheb. Yog tias qhov poob siab absorber tawg, koj tuaj yeem caij mus ntxiv rau ib ntus.
Lub ncua kev kawm ntawv strut yog ib tug complex chav tsev, lub ntsiab ntawm uas yog ib tug roj los yog gas-filled telescopic shock absorber. Lub caij nplooj ntoos hlav steel hnav rau ntawm nws (tej zaum yuav tsis tuaj ntawm qee qhov racks) ua lub caij nplooj ntoos hlav. Lub sab sauv ntawm lub khib yog txuas nrog lub cev los ntawm ib tug thrust bearing.
Qhov qis kawg yog txuas rau lub kauj khawm los ntawm txoj kev uas ntsiag to. Qhov kev tsim no muab kev txav mus los hauv lub dav hlau kab rov tav. Yog li, qhov poob siab absorber strut ua kom cov kev taw qhia ntawm lub log nyob rau hauv qhov chaw, kev ncua ntawm lub cev thiab damping ntawm kev co - ob qho tib si ntsug thiab sab.
Cov khib nyiab yog lub zog tseem ceeb uas siv cov khoom hnyav thiab yuav tsum hnav. Qhov tseeb, nws yuav tsum suav tias yog cov khoom siv tau. Nws tsis yog qhov ua tau mus txuas ntxiv nrog lub khib nyiab tawg.
Vim li cas cov teeb meem khib tsis tuaj yeem tsis quav ntsej. suav nyiaj
Vim yog qhov poob siab absorber los yog hnav tawm struts, kev sib cuag ntawm lub log nrog txoj kev deteriorates, uas cuam tshuam tsis zoo rau kev ruaj ntseg thiab kev tswj xyuas. Qhov no yog tshwj xeeb tshaj yog pom thaum lub sij hawm ntse maneuvers ntawm ceev. Kev coj cwj pwm tsis zoo ntawm lub tsheb ua rau muaj kev pheej hmoo ntawm kev sib tsoo.
Rau cov neeg uas qhov no suab tsis txaus ntseeg, nws tsim nyog saib qhov teeb meem los ntawm kev saib nyiaj txiag.
Raws li cov struts hnav tawm, tag nrho cov kev vibrations pib xa mus rau lub cev, lub load ntawm lub undercarriage Cheebtsam, raws li zoo raws li lub kauj, nce, pab txhawb rau lawv ceev ceev. Nres ncoo thiab discs yuav puas.
Lub faulty shock absorber, txawm tias muaj qhov tsis sib xws ntawm lub log me ntsis, ua rau lub log tsheb hnyav thiab tsis sib xws, txo lawv txoj kev pab cuam lub neej.
Nws yog ib qho yooj yim los xam thiab xyuas kom meej tias lub sij hawm hloov ntawm cov racks hnav yuav zam kev siv nyiaj ntau dua yav tom ntej.
diagnostics
Thaum lub sijhawm ua haujlwm ntawm lub tsheb, cov khoom poob siab feem ntau ua haujlwm 3-4 xyoos, feem ntau ntau dua. Tab sis lub sijhawm no tuaj yeem txo qis yog tias koj txiav txim siab txuag nyiaj thiab yuav khoom pheej yig tsis zoo. Cov peev txheej ntawm cov racks kuj nyob ntawm qhov tseeb installation, tsav tsheb style thiab txoj kev.
Nws ua rau tsis muaj kev txiav txim siab los sim manually pob zeb lub tsheb los txiav txim siab txog kev noj qab haus huv ntawm cov shock absorbers. Qhov tseeb amplitude ntawm lub tsheb buildup nyob rau hauv cov lus tsa suab yog ntau dua, yog li no txoj kev yuav tsuas qhia tag nrho cov poob siab absorbers.
Ntau ntau txog lub xeev ntawm cov racks yuav qhia tus cwj pwm ntawm lub tsheb hauv kev txav. Cov tsos mob hauv qab no yuav qhia tau tias muaj teeb meem:
- khob los yog creaking thaum tsav tsheb;
- tseem ceeb co thiab ntev damping ntawm vibrations ntawm lub tshuab lub cev;
- deterioration nyob rau hauv tuav, tshwj xeeb tshaj yog pom thaum nkag mus rau ib tug tig ntawm ceev;
- nce kev ncua deb ntawm qhov tsis muaj teeb meem nrog lub brakes;
- Thaum lub sij hawm acceleration, lub rear ntawm lub tsheb squats noticeably, thiab thaum braking, nws nods;
- pom tseeb ib qho ntawm cov kua dej ntws tawm vim yog hnav poob siab absorber roj foob;
- tsis sib xws log hnav;
- deformation ntawm lub shock absorber lub tog raj kheej, lub caij nplooj ntoos hlav corrosion los yog lwm yam kev puas tsuaj rau lub strut ntsiab.
Kev kuaj pom tseeb dua tuaj yeem ua rau ntawm qhov chaw pabcuam, uas muaj qhov tshwj xeeb sawv ntsug. Lub tsheb yog rocked rau ntawm nws, thiab cov sensors sau lub amplitude ntawm lub vibrations. Yog li ntawd, lub kaw lus txiav txim siab txog lub neej ntawm cov racks uas yog feem pua, thiab cov kws kho mob tshwj xeeb muab cov lus xaus rau qhov ua tau ntawm lawv txoj haujlwm ntxiv.
Kho lossis hloov
Ncaj nraim shock absorbers yog xyaum tsis raug kho. Yog tias peb tab tom tham txog racks, ces qee qhov chaw pabcuam yuav muab cov kev pabcuam zoo li no. Tab sis nws yuav tsum tau nco ntsoov tias rau kev kho, feem ntau yuav, cov khoom siv yuav raug siv, thiab kev hloov pauv yuav ua rau tus qauv tsim uas yuav cuam tshuam rau kev nyab xeeb. 50 txhiab kilometers yog qhov siab tshaj plaws uas koj tuaj yeem lav tau tom qab kho qhov no.
Nws yog qhov ntse dua los yuav thiab nruab racks tshiab. Ua ntej, koj yuav hnov qhov txawv tam sim ntawd, thiab qhov thib ob, thaum lub sijhawm ua haujlwm ib txwm koj yuav tsis nco qab txog qhov teeb meem rau ntau xyoo.
Rack xaiv
Tom qab hloov cov racks, tus cwj pwm ntawm lub tsheb ntawm txoj kev tuaj yeem hloov tau zoo heev. Ua ntej tshaj plaws, nws nyob ntawm hom kev poob siab absorber.
Roj shock absorbers feem ntau pom muaj nyob rau hauv cov qauv siv nyiaj txiag. Lawv zoo heev rau kev ntsuas kev tsav tsheb hauv nroog, tab sis ntawm kev kub ceev vim overheating thiab foaming ntawm cov roj, lawv efficiency yog sharply txo.
Nyob rau lub caij ntuj no, xws li kev poob siab absorbers yuav tsum tau sov so, yog li ua ntej kom nrawm, koj yuav tsum tau tsav ntawm qhov ceev rau qee lub sijhawm.
Qhov kev xaiv zoo tshaj plaws tuaj yeem suav tias yog roj-roj shock absorbers. Txawm hais tias lawv yog kwv yees li 20 feem pua ntau dua, lawv muab kev tuav zoo ntawm txhua qhov nrawm.
Nyob rau hauv txhua rooj plaub, nws yog zoo dua mus yuav ib tug thawj spare qhov chaw los yog ib tug analogue los ntawm zoo-tsim manufacturers -,,,. Xws li kev yuav khoom yuav them nrog kev ntseeg siab thiab lub neej ua haujlwm ntev.
Thiab nco ntsoov: txhawm rau kom muaj kev ruaj ntseg ntawm lub tsheb, nws yog ib qho tsim nyog yuav tsum tau hloov cov racks ua khub - 2 rear lossis 2 pem hauv ntej.
