Ezimotweni eziningi zanamuhla kanye nemishini ekhethekile, indawo yokumisa i-hood yakudala ngendlela yenduku ithathwa ama-absorbers akhethekile (noma iziphethu zegesi).Funda konke mayelana nama-hood shock absorbers, inhloso yawo, izinhlobo ezikhona nezici zedizayini, ukugcinwa nokulungisa esihlokweni.
Inhloso ye-hood shock absorber
Ezimotweni zesimanje kanye nezinye izinto zokusebenza, ukunakwa okukhulu kakhulu kukhokhwa ekuphepheni kwabantu ngesikhathi sokusebenza nokugcinwa.Amathuluzi amasha uma kuqhathaniswa aqinisekisa ukuphepha kanye lula ekunakekeleni nasekulungiseni okokusebenza ahlanganisa ama-absorber ahlukahlukene (izitobhi zegesi) zehood.Le ngxenye elula yaqala ukufakwa ezimotweni, ogandaganda, imishini ekhethekile nemishini ehlukahlukene muva nje, kodwa isivele yaqashelwa futhi, mhlawumbe, esikhathini esizayo izoshintsha ngokuphelele izitobhi zebha ezingalungile nezingathembeki kakhulu.
I-hood shock absorber noma, njengoba kuvame ukubizwa kanjalo, isitobhi segesi iyithuluzi lokuvula/ukuvala ngokuphephile ihood nokuyigcina ivuliwe.Le ngxenye ixazulula izinkinga ezimbalwa:
- Usizo ekuvuleni i-hood - i-stop iphakamisa i-hood, ngakho-ke umnikazi wemoto noma umakhenikha akudingeki enze umzamo futhi adonse izandla zakhe phezulu;
- Ukuvulwa nokuvala i-hood ngaphandle kokushaqeka - i-shock absorber ivimbela ukushaqeka okwenzeka ezindaweni ezimbi kakhulu ze-hood;
- Ukubamba okuthembekile kwe-hood endaweni evulekile.
Ngaphezu kwalokho, i-shock absorber ivikela i-hood ngokwayo kanye nokuvala uphawu okuseduze kanye nezingxenye zomzimba kusuka ekukhubazekeni okungenzeka ngesikhathi sokuthinteka.Ngakho-ke, ukuba khona kwe-hood shock absorber kwandisa ukuphila kwalezi zingxenye, futhi kwandisa kakhulu ukusebenza kalula, ukugcinwa nokulungiswa kwezimoto ezihlomele.
Izinhlobo nesimiso sokusebenza kwe-hood shock absorbers (iziphethu zegesi)
Kufanele kushiwo ngaso leso sikhathi ukuthi wonke ama-absorber hood shock asetshenziswa namuhla ayiziphethu zegesi, afanayo ekwakhiweni nasesimisweni sokusebenza kwemithombo yegesi yefenisha (noma ukuphakamisa igesi).Kodwa-ke, kwezobuchwepheshe, ngokungafani nokukhiqizwa kwefenisha, kusetshenziswa izinhlobo ezimbili ze-shock absorbers:
- Igesi (noma i-pneumatic) ene-damping enamandla;
- Uwoyela wegesi (noma i-hydropneumatic) ene-hydraulic damping.
Ama-absorbers wegesi ngokuvamile ahlelwe kalula.Ziyi-cylinder ngaphakathi okukhona i-piston phezu kwenduku.I-outlet of the rod from the cylinder is hermetically seal with a gland assembly ukuvimbela ukuvuza kwegesi.Ezindongeni ze-cylinder kukhona iziteshi lapho, ngesikhathi sokusebenza kwe-shock absorber, igesi igeleza isuka komunye umgodi iya kwesinye.Isilinda sigcwaliswa ngegesi (imvamisa i-nitrogen) ngengcindezi ephezulu.
I-gas spring isebenza kanje.Lapho i-hood ivaliwe, i-absorber shock iyacindezelwa, ngenxa yalokho kukhona ivolumu ethile yegesi ngaphansi kwengcindezi ephakeme endaweni engenhla-piston.Lapho uvula izingidi ze-hood, ingcindezi yegesi ku-absorber shock idlula isisindo se-hood, ngenxa yalokho ikhuphuka.Esikhathini esithile, i-piston iwela iziteshi zomoya lapho igesi ingena khona endaweni ye-piston, ngenxa yalokho ukucindezela kwesikhala esingenhla se-piston kwehla futhi ijubane lokuphakamisa i-hood liyancipha.Ngokuqhubeka nokunyakaza, i-piston ivala iziteshi, futhi phezulu kokuvula i-hood, i-piston ima kahle ngesendlalelo segesi esiphumela.Lapho i-hood ivaliwe, konke kwenzeka ngokulandelana, kodwa umfutho wokuqala wokuhamba kwe-hood unikezwa ngezandla zomuntu.
I-Dynamic damping isetshenziswa ku-gas shock absorber.Ukuphakamisa nokwehliswa kwe-hood ngenxa yokwehla okuqhubekayo kwengcindezi yegesi kwenzeka ngesivinini esinciphayo, futhi esigabeni sokugcina ihood ima ngokushelela ngenxa yokumiswa kwepiston "emcamelo" wegesi.
Imithombo ye-Hydropneumatic inomshini ofanayo, kodwa umehluko owodwa: iqukethe inani elithile lamafutha, lapho i-piston icwiliswa khona lapho i-hood iphakanyiswa.I-hydraulic damping isetshenziswa kulezi zinto ezidonsa ukushaqeka, njengoba umthelela we-hood lapho izikhundla ezidlulele zifinyelelwa ucinywa uwoyela ngenxa ye-viscosity yawo.
I-Hydropneumatic shock absorbers, ngokungafani ne-pneumatic shock absorbers, iphakamisa ihood ngokushesha futhi ngaphandle kokunciphisa isivinini kuyo yonke indawo, kodwa ama-absorber we-pneumatic shock avula ukuvuleka okushelelayo ngamandla amancane ezindaweni ezimbi kakhulu.Naphezu kwalomehluko, namuhla zombili izinhlobo zemithombo yegesi zilingana nokusatshalaliswa okufanayo.
Izici zokuklama nezici ze-hood shock absorbers
Ngokwesakhiwo, wonke ama-absorber hood shock (iziphethu zegesi noma izitobhi) ayafana.Ziyi-cylinder, ukusuka ohlangothini olulodwa lapho kuphuma induku ye-piston.Ekupheleni kwe-cylinder kanye nokuphela kwenduku, amalunga ebhola ayenziwa, ngosizo lapho i-shock absorber ifakwe ku-hood kanye nomzimba.Ngokuvamile, ama-hinges akhiwe ngesisekelo sezikhonkwane zebhola anamacebiso anezintambo, ingxenye yebhola ibanjwe ukukhiya ku-absorber shock, futhi ngosizo lwengxenye enezintambo kanye ne-nut, iphinikhodi ifakwe kubakaki.
Ngokuvamile, ukubamba i-hood, kwanele ukuba ne-absorber eyodwa yokushaqeka, kodwa ezimotweni eziningi, amagandaganda nezinye izinto ezisetshenziswayo ezinama-hood anzima, ama-absorbers amabili asetshenziswa ngesikhathi esisodwa.
Ukufakwa kwe-shock absorbers kwenziwa endaweni lapho, lapho induku inwetshiwe ngokugcwele, i-hood ivuliwe ngokugcwele.Kulokhu, ukuqondiswa kwe-shock absorber ngokuhlobene ne-hood nomzimba kwenziwa ngokuya ngohlobo lwayo:
- I-Pneumatic (gas) shock absorbers - ingafakwa kunoma iyiphi indawo, kokubili ngenduku phansi (emzimbeni) kanye nenduku phezulu (kuya ku-hood).Ukuma emkhathini akuphazamisi umsebenzi wabo;
- I-Hydropneumatic (i-gas-oil) i-shock absorbers - kufanele ifakwe endaweni "yenduku phansi", ngoba kulokhu ungqimba lwamafutha luzohlala lukhona ngaphansi kwe-shock absorber, okuqinisekisa ukusebenza kwayo kahle kakhulu.
I-gas stop ye-hood iyingxenye elula, kodwa futhi idinga ukuhambisana nemithetho ethile yokusebenza nokugcinwa.
Izinkinga zokugcinwa nokulungiswa kwama-hood shock absorbers
Ukwandisa impilo yesitobhi segesi ye-hood, kufanele ulandele izincomo ezimbalwa ezilula:
- Ungalethi i-hood endaweni ephezulu ngamandla esandla - i-hood kufanele ivule kuphela ngaphansi kwamandla adalwe yi-shock absorber;
- Esikhathini sasebusika, udinga ukuphakamisa nokuvala i-hood ngokushelela futhi ngaphandle kwama-jerks, usize ngezandla zakho, ngaphandle kwalokho kukhona ingozi yokulimaza i-frozen shock absorber;
- Ama-absorbers okuthuthumela awavunyelwe ukuba ahlakazwe, abhekane nokushaqeka, ukushisa ngokweqile, njll - lokhu kugcwele ukulimala okunzima, njengoba kukhona igesi ngaphansi kwengcindezi ephezulu ngaphakathi.
Uma kwenzeka ukuphuka kwe-shock absorber, lapho i-depressurized noma ukuvuza kwamafutha (okuthinta ukusebenza kwayo), ingxenye kufanele ishintshwe emhlanganweni.Lapho uthenga i-absorber entsha yokushaqeka, kuyadingeka ukuncika ezincomweni zomkhiqizi, kodwa kuyamukeleka ukuyifaka esikhundleni sezingxenye ezifanayo nezici.Into eyinhloko ukuthi i-shock absorber ithuthukisa amandla okwanele okuphakamisa i-hood futhi inobude obanele.
Ukushintsha i-hood shock absorber kwehla ekukhululeni nasekuqiniseni amantongomane amabili, kwezinye izimo kungase kudingeke ukuthi kushintshwe abakaki.Lapho ufaka i-absorber entsha yokushaqeka, kuyadingeka ukuhambisana nezidingo zokuma kwayo, okungukuthi, kuye ngohlobo, beka induku phezulu noma induku phansi.Amaphutha okufaka awamukeleki, njengoba lokhu kuzoholela ekusebenzeni okungalungile kwe-shock absorber futhi kwandise ingozi yokulimala lapho kwenziwa umsebenzi endaweni yenjini.
Ngokusebenza kahle kwe-hood shock absorber futhi ngokulungiswa kwayo okulungile, ukusebenza kwemoto, ugandaganda noma olunye uhlobo lwemishini kuzoba lula futhi kuphephe kuzo zonke izimo.
