Iyini ingalo ye-valve rocker ne-tappet
Ingalo ye-vela ye-valve valve rocker ne-tappet yizingxenye ezibalulekile ze-valve ye-valve ye-automobile yemoto, futhi ngamunye wabo unomsebenzi othize nomphumela.
Ingalo ye-valve rocker
I-Valve Rocker ARM iyingxenye ebalulekile yendlela ye-Valve Valve, indima yayo eyinhloko ukusebenza ne-camshaft ukuqinisekisa ukuvula okufika ngesikhathi nokuvalwa kwe-valve, ukuze uqedele inqubo yokudla kanye nokuqeda inqubo. Ingalo ye-rocker iyi-lever engalweni emibili enomgodi ophakathi nomhlaba ophakathi nendawo. Ingalo emfushane ifakwe isikulufa sokulungiswa kwe-valve ye-valve ohlangothini olulodwa, futhi ingalo ende ihlinzekwa ngobuso bokusebenza kwe-arc ukucindezela i-valve.
I-Valve Tappet
Umsebenzi oyinhloko we-tappet ye-valve ukudlulisa ukunyakaza namandla we-camshaft kwinduku ye-push noma i-valve, bese ucindezela induku yokucindezela noma i-valve ukunqoba amandla e-valve ntwasahlobo. I-tappet idinga ukumelana namandla e-lateral asetshenziswe yi-cam ngesikhathi sokusebenza bese uyidlulisela emzimbeni noma ekhanda lesilinda. Ama-tappets angahlukaniswa ngama-tappets asebenza ngomshini futhi ahlotshisiwe, ngalinye linesakhiwo sakho esithile nomsebenzi:
I-Mechan Tappet: Imvamisa yenziwe ngensimbi ye-alloy noma i-alloy cast iron nge-great virrance. Isakhiwo silula kepha imvume ye-valve idinga ukulungiswa njalo.
I-Hydraulic tappet: isusa ngokuzenzakalelayo imvume ye-valve ngaphandle kokulungiswa futhi yehlise umsindo wokudlulisa. I-hydraulic tappet yakhiwa ngomzimba we-tappet, i-plunger kanye nentwasahlobo yesinxephezelo, njll., Elungiswa ngokuzenzakalelayo ngokucindezela kwamafutha nesenzo sentwasahlobo.
Izimo ezithile zesicelo nezinzuzo nobubi
I-Mechan Tappet: Isakhiwo esilula, kepha dinga ukulungiswa njalo nokulungiswa kwe-valve imvume. Kusebenza ezimweni ezingadingi ukulungiswa okuphezulu.
I-Hydraulic tappet: Isakhiwo esiyinkimbinkimbi kepha singashintshwa ngokuzenzakalelayo, sinciphise umsebenzi wokulungisa, kufanelekile ukuthembeka okuphezulu kanye nezidingo zomsindo zesimo sesehlakalo. I-hydraulic tappet ilungiswa ngokuzenzakalelayo ngesenzo sokucindezela kukawoyela kanye nentwasahlobo, okungasusa i-valve imvume futhi kunciphise umsindo wokuhambisa.
Iqhaza le-Valve Rocker AML kanye ne-tappet ikakhulukazi kufaka phakathi lezo zinto ezilandelayo:
Indima ye-tappet
Umsebenzi oyinhloko we-tappet ukudlulisa i-strust ye-camshaft kwinduku ye-push noma induku ye-valve, bese ucindezela induku ye-push noma i-valve ukunqoba amandla entwasahlobo ye-valve bese uhambisa. Ngasikhathi sinye, ama-tappings abuye athwale amabutho alandelwayo anikezwe ukujikeleza kwe-camshast. I-tappet ingahlukaniswa ngezinhlobo ezimbili: i-tappet ejwayelekile ne-hydraulic tappet:
I-Tappet ejwayelekile: kufaka phakathi i-tappet yokukhunta, i-barrel tappet ne-roller tappet. Ama-Tappets ajwayelekile ayizinhlaka eziqinile futhi awakwazi ukuqeda ngokuzenzakalela imvume ye-valve, ngakho-ke kuyadingeka ukulungisa i-valve imvume njalo.
I-Hydraulic tappet: ingasusa imvume ye-valve yenjini, asikho isidingo sokushintsha i-valve imvume, futhi inganciphisa umsindo wokuhambisa we-valve mechanism. I-hydraulic tappet iguqula ngokuzenzakalelayo i-valve imvume ngokucindezela kukawoyela kanye nesenzo sendawo yokunxephezela ukuqinisekisa ukuthintana okusondele phakathi kwe-valve ne-cam.
Indima ye-rocker ingalo
Umsebenzi oyinhloko we-rocker ingalo ukudlulisa amandla endongeni ye-push noma i-cam kuya e-valve ngemuva kokushintsha indlela yokuvula. Umhlangano we-Rocker ARM uhlanganisa ingalo ye-rocker, shaft ye-rocker arm, isihlalo sokusekelwa, isikulufa sokulungiswa kwe-valve charection nezinye izingxenye. Lezi zingxenye zisebenza ngokubambisana ukuqinisekisa ukuvulwa okunembile nokuvalwa kwe-valve, ngaleyo ndlela kulawulwa ngenqubo yokudla nokuphelelwa amandla futhi kuqinisekiswe ukusebenza okujwayelekile kwenjini.
Umgomo othize wokusebenza
Lapho injini isebenza, i-crankshaft ishayela i-camshaft yokujikeleza ngendlela yokuhambisa, futhi i-cam ku-camshaft idonsela induku ye-push noma i-valve nge-tashet. Lapho ingxenye ephakanyisiwe ye-cam iqhuma ngokumelene ne-tappet, i-tappet idlulisela amandla ku-push rod noma i-valve, ivule i-valve. Ngokujikeleza kwekati, i-valve ivalwa kancane kancane ngaphansi kwesenzo sentwasahlobo. Ingalo ye-rocker idlulisa amandla enduku ye-push noma i-cam, iqinisekisa ukuthi i-valve ivula futhi ivale ngokunembayo.
