Iyini ingalo ye-valve rocker kanye ne-tappet
Ingalo ye-rocker valve yemoto kanye ne-tappet kuyizingxenye ezibalulekile zendlela yokusebenza kwe-valve yenjini yemoto, futhi ngayinye yazo inomsebenzi nomphumela othize.
Ingalo ye-rocker ye-valve
Ingalo ye-rocker ye-valve iyisici esibalulekile sendlela yokusebenza kwe-valve yenjini, indima yayo eyinhloko ukusebenza ne-camshaft ukuqinisekisa ukuvulwa nokuvalwa kwe-valve ngesikhathi, ukuze kuqedwe inqubo yokungenisa nokukhipha umoya. Ingalo ye-rocker iyi-lever enezingalo ezimbili enembobo yomgodi ophakathi njenge-fulcrum. Ingalo emfushane ifakwe isikulufu sokulungisa i-valve clearance ohlangothini olulodwa, kanti ingalo ende inikezwe ubuso obusebenzayo be-arc ukuze kucindezelwe i-valve.
I-valve tappet
Umsebenzi oyinhloko we-valve tappet ukudlulisa ukunyakaza namandla e-camshaft ku-push rod noma i-valve, bese ucindezela i-push rod noma i-valve ukuze unqobe amandla esiphethu se-valve. I-tappet idinga ukumelana namandla aseceleni asetshenziswa yi-CAM ngesikhathi sokusebenza bese iwadlulisela emzimbeni noma ekhanda lesilinda. Ama-tappet angahlukaniswa ngama-tappet emishini kanye ne-hydraulic, ngalinye linesakhiwo salo kanye nomsebenzi walo othize:
I-tappet yomshini: ngokuvamile yenziwe ngensimbi ye-alloy noma insimbi ye-alloy ephikiswayo enokumelana okuhle nokuguguleka. Isakhiwo silula kodwa isikhala se-valve sidinga ukulungiswa njalo.
I-tappet ye-hydraulic: Iqeda ngokuzenzakalelayo ukuvuleka kwe-valve ngaphandle kokulungiswa futhi inciphisa umsindo wokudlulisa. I-tappet ye-hydraulic yakhiwe ngomzimba we-tappet, i-plunger kanye ne-spring compensation, njll., elungiswa ngokuzenzakalelayo yingcindezi kawoyela kanye nokusebenza kwe-spring.
Izimo ezithile zohlelo lokusebenza kanye nezinzuzo kanye nokungalungi
I-tappet yomshini: isakhiwo esilula, kodwa sidinga ukulungiswa njalo kanye nokulungiswa kwesikhala se-valve. Isebenza ezimweni ezingadingi ukulungiswa okuphezulu.
I-tappet ye-hydraulic: isakhiwo esiyinkimbinkimbi kodwa singalungiswa ngokuzenzakalelayo, sinciphise umsebenzi wokulungisa, sifanelekela ukuthembeka okuphezulu nezidingo zomsindo wendawo. I-tappet ye-hydraulic ilungiswa ngokuzenzakalelayo ngesenzo sokucindezela kukawoyela kanye nesipilingi, okungasusa ukuvuleka kwe-valve futhi kunciphise umsindo wokudlulisa.
Indima yengalo ye-valve rocker kanye ne-tappet ihlanganisa kakhulu izici ezilandelayo:
Indima ye-tappet
Umsebenzi oyinhloko we-tappet ukudlulisa ukusunduza kwe-camshaft ku-push rod noma i-valve rod, bese ucindezela i-push rod noma i-valve ukuze unqobe amandla esiphethu se-valve bese uhamba. Ngesikhathi esifanayo, ukuthepha nakho kuthwele amandla aseceleni asetshenziswa ukujikeleza kwe-camshaft. I-tappet ingahlukaniswa ngezinhlobo ezimbili: i-tappet evamile kanye ne-hydraulic tappet:
i-tappet evamile : kufaka phakathi i-fungus tappet, i-barrel tappet kanye ne-roller tappet. Ama-tappet avamile ayizakhiwo eziqinile futhi awakwazi ukususa ngokuzenzakalelayo i-valve clearance, ngakho-ke kuyadingeka ukulungisa i-valve clearance njalo.
I-tappet ye-hydraulic : ingasusa ukuvuleka kwe-valve yenjini, asikho isidingo sokulungisa ukuvuleka kwe-valve, futhi inganciphisa umsindo wokudlulisa wendlela ye-valve yenjini. I-tappet ye-hydraulic ilungisa ngokuzenzakalelayo ukuvuleka kwe-valve ngokusebenzisa ingcindezi kawoyela kanye nesenzo sesiphethu esikhokhelayo ukuqinisekisa ukuthi i-valve ne-CAM ziyaxhumana eduze.
Indima yengalo ye-rocker
Umsebenzi oyinhloko wengalo ye-rocker ukudlulisa amandla kusuka ku-push rod noma i-CAM kuya ku-valve ngemva kokushintsha indlela ukuze ivuleke. I-rocker arm assembly ihlanganisa ingalo ye-rocker, i-rocker arm shaft, isihlalo sokusekela, isikulufu sokulungisa i-valve clearance nezinye izingxenye. Lezi zingxenye zisebenza ndawonye ukuqinisekisa ukuvulwa nokuvalwa okunembile kwe-valve, ngaleyo ndlela zilawula inqubo yokungenisa nokukhipha umoya futhi ziqinisekise ukusebenza okuvamile kwenjini .
Isimiso esiqondile sokusebenza
Uma injini isebenza, i-crankshaft ishayela i-camshaft ukuze ijikeleze ngendlela yokudlulisa, kanti i-CAM eku-camshaft isunduza induku yokusunduza noma ivalvu nge-tashet. Lapho ingxenye ephakanyisiwe ye-CAM isunduza i-tappet, i-tappet idlulisela amandla kunduku yokusunduza noma ivalvu, ivule ivalvu. Ngokuzungeza kwe-CAM, ivalvu ivalwa kancane kancane ngaphansi kwesenzo sesipilingi. Ingalo ye-rocker idlulisela amandla enduku yokusunduza noma i-CAM kuvalvu, iqinisekisa ukuthi ivalvu ivuleka futhi ivaleka ngokunembile.
