Thaum nws rattles thiab khob - Dab tsi ua rau kev vibrations hauv lub tsheb
Tsav tsheb yog qhov tshwj xeeb tshaj yog qab ntxiag thaum nws ua tiav nrog kev nplij siab siab tshaj plaws. Smooth glide ntawm txhua qhov nrawm, suab paj nruag qab ntxiag thiab tsis muaj suab nrov sab nraud - yog qhov zoo npaum li cas nws yog tsav koj lub tsheb. Tab sis yog hais tias nws rattles, co thiab vibrates, ces tsav kev txaus siab sai sai hloov mus rau hauv ib tug tiag tiag kev nyuaj siab. Tsis tas li ntawd, lub tsheb vibrating kuj tuaj yeem ua rau muaj kev puas tsuaj sai thiab ua rau muaj xwm txheej tsav tsheb txaus ntshai. Tias yog vim li cas koj yuav tsum nco ntsoov tshawb xyuas txawm tias qhov kev vibrations tsis muaj zog. Feem ntau, qhov xwm txheej tsuas yog zuj zus.
Feem ntau ua rau, ib qho tsos mob
Lub tsheb vibrating yog ib qho kev kuaj mob uas tsis yog tshwj xeeb. . Muaj ob peb yam ua tau rau tus mob no. Tej yam ua rau lub tsheb vibration yog:
- taug qab geometry
- chassis
- cav
- tso pa system
- log tsheb
- cardan ncej
Yog li ntawd, nws yog ib qho tsim nyog yuav tau txiav txim siab ntau dua vim li cas rau qhov kev hloov ntawm kev tsav tsheb. Qhov no yog ua tiav systematically.
| 1. Lub vibrations tshwm sim ntawm qhov ceev? 2. Kev vibrations kuj tshwm sim thaum lub tsheb raug kaw tab sis dov? 3. Puas muaj kev vibrations thaum lub tsheb nres nrog lub cav khiav? 4. Kev vibrations tshwm sim thaum nres? |
1. Kev vibrations hauv lub tsheb, nyob ntawm qhov ceev.
Yog tias kev vibrations tshwm sim tsuas yog thaum muaj kev kub ceev, qhov no feem ntau yog vim log tsheb los yog counterweights . Lawv tuaj yeem tawm ntawm ntug. Tom qab ntawd, lub log tsis tig "hauv lub voj voog". Txhawm rau kho qhov teeb meem, mus ntsib koj lub rooj cob qhia ze tshaj plaws thiab ua kom lub log sib npaug.
Txawm hais tias qhov kev puas tsuaj tuaj yeem kho tau sai thiab pheej yig, nws yuav tsum tsis txhob ncua sijhawm ntev. Log vibration cuam tshuam rau tag nrho lub kauj mechanism . Tie rod xaus, stabilizers thiab wishbones kuj raug kev txom nyem.
 Yog hais tias ib lub kauj iav puas lawm, lub tsheb yuav co txawm nyob rau hauv qis ceev . Txawm nyob rau ceev 20 km / h muaj qhov "mos" tsav tsheb xav tias yuav tsis zoo thiab tsis zoo ntawm kev nrawm dua. Qhov no tshwm sim, piv txwv li, thaum ntaus ib tug curb ntawm lub kaum sab xis. Tom qab ntawd cov pob txha feem ntau khoov me ntsis thiab lub pob sib koom ua tsis tiav. Ces ob leeg yuav tsum tau hloov. |
| Cov tsos mob zoo sib xws tshwm sim thaum lub shock absorbers ua tsis tiav. . Lub tsheb ces bounces ntau dhau, ua rau nws nyuaj rau taug qab. Yog hais tias lub tsheb yog crook, lub springs yog tawg. Nyob rau hauv cov ntaub ntawv no, ib yam nkaus thiab, lub tshuab tsis thaws kom zoo thiab pib vibrate. |
| Cov log tsheb qub thiab tsis zoo kuj tuaj yeem ua rau muaj kev vibration. . Yog hais tias lub log tsheb muaj "brake phaj" los yog cov carcass tawg ntawm sab, nws yuav pib vibrate thaum tsav tsheb. Qhov kev puas tsuaj no yuav tsum tau kho tam sim ntawd, vim tias lub log tsheb tuaj yeem tawg tau txhua lub sijhawm. |
| Yog hais tias lub axles khau raj puas thiab roj tau leaked , lub log bearing yuav kub heev. Nws kuj tuaj yeem pom tau vim muaj kev vibrations thaum tsav tsheb. Nws yooj yim heev kom pom: cov log tau tig tag nrho txoj kev tawm, thiab koj tuaj yeem saib tom qab lub kauj. Yog tias txhua yam npog hauv cov roj dub, koj paub qhov twg cov kev vibrations tuaj. .tsuas txoj kev tawm yog disassemble txhua yam thiab hloov lub anther thiab log bearing. Txawm li cas los xij, nco ntsoov , uas axle khau raj yuav puas los ntawm kev laus los yog marten tom. Hauv ob qho xwm txheej tag nrho lwm yam khoom siv roj hmab xws li hoses, lub tes tsho thiab rwb thaiv tsev yuav tsum tau kuaj xyuas. Feem ntau, koj yuav pom lwm qhov uas puas lawm. |
Qhov ua rau ntawm kev vibrations ntawm lub log tseem tsis tau txheeb xyuas: Yog hais tias lub log bolts yog xoob los yog pib xoob, lawv yuav qhia qhov no nrog lub zog vibration ntawm lub log. . Qhov no yog ib tug loj tsim yuam kev, thiab nws yuav tsum tau kho sai nrog tus ntoo khaub lig. Tag nrho cov log yuav tsum tau nruj nrog lub torque ciaj ntswj ntawm qhov chaw ua haujlwm tshwj xeeb ze tshaj plaws.Txawm li cas los xij, lub log tsis xoob li ntawd. . Yog hais tias lawv tau raug mounted ua ntej ces nws muaj feem ntau yuav muaj kev cuam tshuam sab nraud. Hauv qhov no, koj yuav tsum ceeb toom rau tub ceev xwm. |
2. Kev vibrations thaum tsav tsheb
Yog tias lub tsheb vibrates thaum lub cav tawm, ces qhov teeb meem yuav raug txo kom tsawg kev ncua , kauj tsav tsheb los yog log tsheb .
3. Kev vibrations thaum lub tsheb nres tab sis qhib
Yog tias qhov kev vibrations tuaj ntawm lub cav, qhov no yuav yog vim li cas hauv qab no:
- Faulty cav mount
- ib lossis ntau lub tog raj kheej tsis ua haujlwm
- clogged roj lim
- tsis xws luag dual loj flywheel
| Yog hais tias lub cav mount yog xoob los yog txawm tawg , qhov no txhais tau hais tias lub cev muaj zog tsis raug txuas nrog nws cov ntsiab lus damping. Tom qab ntawd nws pib mus ncig thiab ua rau rumble thiab co ntawm lub cev. |
| Lub txim hluav taws xob tsis raug lossis xoob hluav taws xob hluav taws xob yuav txaus ua rau ib lub tog raj kheej tsis ua haujlwm. . Tom qab ntawd lub tog raj kheej tsuas yog "rub" tus so. Qhov no ua rau lub cav tsis sib haum me ntsis, uas tuaj yeem pom tshwj xeeb tshaj yog thaum lub tsheb nres. Txawm li cas los xij, nws yog qhov zoo tshaj kom paub qhov txhaum no thaum tsav tsheb:lub tsheb poob ntau lub zog thiab tsis nrawm dua li qub. |
| Tib yam tshwm sim yog tias cov roj lim tau txhaws. . Nws tsuas yog kis tau roj av lossis diesel tsis sib npaug, uas txhais tau hais tias lub cav tsis tau muab cov roj sib npaug. Nws kuj tuaj yeem ua rau muaj kev vibrations thiab tsis muaj zog. |
| Dual mass flywheel yog ib feem ntawm lub clutch. . Nws yog ib tug loj rotating tivthaiv uas yuav tsum tau rau smooth shifting. Txawm li cas los xij, nws yog lubricated tas mus li thiab yog li ntawd muaj lub neej ua haujlwm tsawg. Thaum lub roj nplua nyeem tau siv tom qab 150 km khiav, nws qhov kev txiav txim ua qhov sib txawv: es tsis txhob ua kom lub tsheb du, nws rumbles ntau dua, vibrates thiab khob. Tib txoj kev tawm yog los hloov nws, tab sis nws kim heev. Qhov kev ua txhaum no tuaj yeem txo qis dua: yog tias nws rattles thaum hloov lub zog, nws feem ntau yog ob pawg flywheel, txhawm rau tiv thaiv qhov txhaum no, nws raug nquahu kom hloov lub dual pawg flywheel raws li kev ceev faj thaum kho lub clutch. Txawm hais tias lub dual-mass flywheel tseem muaj qhov seem kev pab cuam lub neej 20 km Nws feem ntau tsis tsim nyog tos ntev li ntawd. Yog hais tias txhua yam twb disassembled, koj yuav tsum nqis peev txog 250 Euro thiab txuag cov nqi kho tom ntej. |
| Ntawm qhov tod tes, nws tseem pheej yig dua yog tias cov kev vibrations los ntawm qhov tso pa tawm: yog tias cov roj hmab khaws cia ploj lawm, cov pa tawm tuaj yeem tsoo hauv qab . Nyob ntawm seb qhov no tshwm sim sai npaum li cas los yog ntau npaum li cas, nws yuav hnov zoo li kev vibration. |
| Tib yam tshwm sim yog tias cov screws ntawm lub manifold yog xoob . Qhov no tsis tshua muaj, tab sis qee zaum nws tshwm sim. Tej kev ua txhaum no feem ntau yuav raug kho nyob rau hauv ob peb kauj ruam yooj yim. |
4. Kev vibrations hauv lub tsheb thaum nres
Yog tias muaj kev vibration muaj zog thaum braking, feem ntau qhov no tsuas muaj ib qho laj thawj: lub brake disc tau ua wavy . Qhov no tshwm sim thaum lub discs overheat, lub nres pistons txeeb, los yog cov khoom siv tsis zoo siv rau ntawm lub disc lossis cov ntaub qhwv.
Xaus: Kev kuaj mob zoo, kev tsav tsheb nyab xeeb
Kev txheeb xyuas qhov ua rau muaj kev vibrations hauv lub tsheb ua rau nws yooj yim dua los nrhiav thiab kho qhov tsis raug. Txawm hais tias koj xav kho qhov kev puas tsuaj koj tus kheej los yog kho nws los ntawm kev cob qhia: los ntawm kev piav qhia cov tsos mob kom raug, kev tshawb nrhiav qhov laj thawj ua sai dua.
