Ngokomlando, ezimotweni ezingemuva kwe-hatchback ne-station wagon, i-tailgate ivuleka phezulu.Nokho, kulokhu, kunenkinga yokugcina umnyango uvuliwe.Le nkinga ixazululwa ngempumelelo yi-gas shock absorbers - funda ngalezi zingxenye, izici zazo, ukugcinwa nokulungisa esihlokweni.
Inhloso yama-absorber omnyango wangemuva
Izimoto eziningi zakuleli nezakwamanye amazwe ngemuva kwe-hatchback ne-station wagon zifakwe i-tailgate evuleka ibheke phezulu.Lesi sixazululo silula futhi silula kakhulu, ngoba ungasebenzisa ama-hinges afanayo ukuvula umnyango, futhi umnyango ngokwawo kulula ukulinganisa kunokuba uvule eceleni.Ngakolunye uhlangothi, ukuvula i-tailgate phezulu kudinga izinyathelo ezikhethekile zokuqinisekisa ukunethezeka nokuphepha.Okokuqala, kuyadingeka ukuqinisekisa ukuthi umnyango ugcinwe ngokuphephile endaweni ephezulu, kanye nokusiza ukuvula umnyango kubantu abafushane.Yonke le misebenzi ixazululwa ngosizo lwe-shock absorbers ye-tailgate.
I-tailgate shock absorber (noma i-gas stop) iyisisetshenziswa somoya noma se-hydropneumatic esixazulula inani lemisebenzi:
- Usizo ekuvuleni umnyango - i-shock absorber iphakamisa ngokuzenzakalelayo umnyango, isindisa amandla omnikazi wemoto;
- Ukunciphisa ukushaqeka nokushaqeka lapho umnyango ongemuva uvulwa futhi uvalwa ngokugcwele - ingxenye ivimbela ukushaqeka okwenzeka lapho umnyango uphakanyiswa futhi wehliselwa ezindaweni ezimbi kakhulu;
- Ukuqinisekisa ukuphepha lapho umnyango uvulekile - i-shock absorber igcina umnyango endaweni ephezulu ngaphandle kokusetshenziswa kwezitobhi ezengeziwe, ukuvimbela ukuvala ngaphansi kwesisindo sawo noma imithwalo yomoya ebuthakathaka;
- Ukuvikelwa komnyango ongemuva, izakhi zokuvala kanye nezakhiwo zomzimba wemoto ekuguqulweni nasekubhujisweni lapho umnyango uvaliwe.
Kodwa okubaluleke kakhulu, i-tailgate shock absorber yandisa ukunethezeka kwemoto, njengoba ikuvumela ukuba uvule kalula futhi uvale i-trunk ngisho nezandla zakho zigcwele, esimweni sezulu esibandayo, lapho imoto ingcolile, njll. Ngakho-ke, i-tailgate shock absorber. iyingxenye ebalulekile yemoto, okwenza kube lula, ntofontofo futhi iphephe.
Izinhlobo, idivayisi kanye nokusebenza kwe-shock absorbers (izitobhi) zomnyango ongemuva
Njengamanje, kusetshenziswa izinhlobo ezimbili ze-tailgate shock absorbers:
- Pneumatic (noma igesi);
- Hydropneumatic (noma igesi-amafutha).
Lawa ma-absorber othusayo ayahluka kuyo yomibili imininingwane yokuklama kanye nezici zomsebenzi:
- I-Dynamic damping isetshenziswa ku-pneumatic (gas) shock absorbers;
- Ku-hydropneumatic (gas-oil) shock absorbers, i-hydraulic damping isetshenziswa.
Kulula ukuqonda umehluko phakathi kwalezi zinhlobo zamadivayisi, kwanele ukuhlakaza isakhiwo sabo kanye nesimiso sokusebenza.
Zombili izinhlobo ze-shock absorbers zinomklamo ofanayo.Asekelwe kusilinda esigcwele i-nitrogen ngaphansi kwengcindezi ephakeme ngokwanele.Ngaphakathi kusilinda kune-piston exhunywe ngokuqinile endongeni.Induku ngokwayo ikhishwa ngomhlangano we-gland - yenza imisebenzi yomibili yokugcoba induku nokuvala isilinda.Engxenyeni ephakathi yesilinda, ezindongeni zayo, kuneziteshi zegesi ze-cross-section encane, lapho igesi evela endaweni engenhla ye-piston ingageleza endaweni ye-piston nakwehlukile.
Akukho okunye ku-absorber shock, futhi ku-hydropneumatic shock absorber, ohlangothini lwenduku, kukhona ukugeza kwamafutha.Futhi, i-piston inomehluko othile - inama-valve.Ubukhona bukawoyela obunikeza ukudambisa amanzi okudonsa amanzi, okuzoxoxwa ngakho ngezansi.
I-pneumatic shock absorber ye-tailgate inomgomo olula wokusebenza.Lapho umnyango uvaliwe, i-absorber shock iyacindezelwa, futhi ekamelweni elingaphezu kwepiston kukhona umthamo omkhulu wegesi ngaphansi kwengcindezi ephezulu.Uma uvula umnyango ongemuva, ingcindezi yegesi ayisalingani ngokukhiya, idlula isisindo somnyango - ngenxa yalokho, i-piston iphushwa ngaphandle, futhi umnyango ukhuphuka kahle.Lapho i-piston ifinyelela engxenyeni ephakathi yesilinda, kuvuleka umgudu lapho igesi igeleza kancane iye kwelinye (piston) igumbi.Ukucindezela kuleli gumbi kuyanda, ngakho i-piston iyancipha kancane kancane futhi ijubane lokuvula umnyango liyancipha.Lapho iphuzu eliphezulu lifinyelelwa, umnyango uyama ngokuphelele, futhi umthelela udambisa "umcamelo" wegesi owakha ngaphansi kwepiston.
Ukuvala umnyango, kufanele udonswe phansi ngesandla - kulokhu, i-piston izovula kabusha iziteshi zegesi ngesikhathi sokunyakaza kwayo, ingxenye yegesi izogeleza endaweni ye-piston engenhla, futhi lapho umnyango uvaliwe ngokuqhubekayo. izoncipha futhi iqongelele amandla adingekayo ekuvuleni okulandelayo komnyango.
I-oil shock absorber isebenza ngendlela efanayo, kodwa lapho iphuzu eliphezulu lifinyelelwa, i-piston icwiliswa emafutheni, ngaleyo ndlela inciphise umthelela.Futhi kulokhu kudonsa ukushaqeka, igesi igeleza phakathi kwamakamelo ngendlela ehluke kancane, kodwa azikho umehluko oyinhloko ovela ku-pneumatic shock absorber kuwo.
Njengoba sekushiwo kakade, okuthiwa i-dynamic damping isetshenziswa ezitobhini zegesi ye-pneumatic.Kuboniswa ukuthi ijubane lokuvula umnyango liyancipha kancane kancane kusukela ekuqaleni kwe-piston ukuya phezulu, futhi umnyango ufika endaweni ephezulu ngesivinini esiphansi.Okusho ukuthi, igalelo lidambisiwe hhayi esigabeni sokugcina sokuvula i-tailgate, kodwa njengokungathi kucishiwe kuyo yonke ingxenye yethrafikhi.
I-hydraulic damping inomehluko obalulekile: umthelela udanjiswa kuphela engxenyeni yokugcina yokuvuleka komnyango ngokucwilisa ipiston emafutheni.Kulokhu, umnyango kuyo yonke ingxenye yendlela uvuleka ngesivinini esiphezulu futhi cishe esifanayo, futhi ubhuleki ngaphambi nje kokufinyelela iphuzu eliphezulu.
Ukuklama kanye nezici zokufakwa kwezitobhi zegesi zomnyango ongemuva
Zombili izinhlobo ze-shock absorbers zinokuklama okufanayo kanye nesakhiwo.Ziyi-cylinder (imvamisa ipendiwe emnyama ukuze kube lula futhi ibonakale kalula) okuphuma kuyo isiqu esipholishwe isibuko.Emaphethelweni avaliwe e-cylinder naphezu kwenduku, izinsimbi zenzelwe ukukhwezwa emnyango nasemzimbeni.I-shock absorbers ifakwe i-hinged, ngosizo lwezikhonkwane zebhola, zicindezelwe noma zilungiswe ngenye indlela ezisekelweni ezifanele ekugcineni kwe-shock absorber.Ukufakwa kwezikhonkwane zebhola emzimbeni nasemnyango - ngokusebenzisa izimbobo noma amabakaki akhethekile anamantongomane (imicu inikezwa eminwe yalokhu).
Ama-absorber othusayo, kuye ngohlobo, anezici zokufaka.I-pneumatic-type shock absorbers (igesi) ingafakwa kunoma iyiphi indawo, ngoba ukuqondiswa emkhathini akuthinti ukusebenza kwabo.Ama-absorber we-Hydropneumatic shock angafakwa kuphela nge-stem phansi, ngoba uwoyela kufanele uhlale ungaphezulu kwe-piston, okuqinisekisa izimfanelo ezinhle kakhulu zokudambisa.
Ukugcinwa nokulungiswa kwezinqamuleli ze-tailgate shock
Ama-absorber omnyango wangemuva awadingi ukunakekelwa okukhethekile phakathi nayo yonke impilo yesevisi.Kudingeka kuphela ukuhlola ngezikhathi ezithile lezi zingxenye ngobuqotho bazo futhi kuqashwe ukubukeka kwe-oyela smudges (uma i-hydropneumatic shock absorber).Uma kutholakala ukungasebenzi kahle futhi kukhona ukuwohloka kokusebenza kwe-absorber shock (ayiphakamisi kahle umnyango, ayidambisi ukushaqeka, njll.), kufanele ishintshwe emhlanganweni.
Ukushintsha i-shock absorber kuvame ukwehlela kulokhu okulandelayo:
1.Phakamisa i-tailgate, qinisekisa ukugcinwa kwayo ngesitobhi esengeziwe;
2.Khipha amantongomane amabili abambe izikhonkwane zebhola ze-shock absorber, susa i-shock absorber;
3.Faka i-shock absorber entsha, qinisekisa ukuma kwayo okulungile (i-stem up noma i-rod down, kuye ngokuthi hlobo luni);
4.Qinisa amantongomane ngamandla anconyiwe.
Ukwandisa impilo ye-shock absorbers futhi ukwandise impilo yabo, kufanele ulandele izincomo ezimbalwa zokusebenza ezilula.Ikakhulukazi, akufanele "ubasize" ukuphakamisa umnyango, akufanele uphakamise umnyango ngokucindezela okuqinile, njengoba lokhu kungaholela ekuqhekekeni.Ngenkathi ebandayo, udinga ukuvula i-tailgate ngokucophelela, okuhle kunakho konke ngemuva kokufudumala i-cabin, njengoba ama-absorbers ashubile abandayo futhi asebenze kancane kancane.Futhi-ke, akuvunyelwe ukuqaqa lezi zingxenye, uziphonsa emlilweni, uzibeke ekushayweni okunamandla, njll.
Ngokusebenza ngokucophelela, i-tailgate shock absorber izosebenza isikhathi eside futhi inokwethenjelwa, okwenza imoto ibe yinto ekhululekile futhi elula ezimweni ezihlukahlukene.
