Yintoni ingalo yevalve rocker kunye netappet
Ingalo yevalve yemoto kunye netappet zizinto ezibalulekileyo zendlela yevalve yemoto, kwaye nganye yazo inomsebenzi othile kunye nesiphumo. ...
Ingalo yerokhi yevalve
Ingalo yevalve yevalve yinxalenye ephambili yendlela yevalve ye-injini, indima yayo ephambili kukusebenza necamshaft ukuqinisekisa ukuvulwa nokuvalwa kwangethuba kwevalve, ukuze kugqitywe inkqubo yokungena kunye nokuphuma. Ingalo yerocker yilever enengalo ezimbini kunye nomngxuma weshaft ophakathi njenge fulcrum. Ingalo emfutshane ixhotyiswe ngesikrufu sokulungelelaniswa kwevalve kwelinye icala, kwaye ingalo ende ibonelelwa ngobuso obusebenzayo be-arc ukutyhala ivalve.
I-valve tappet
Umsebenzi ophambili wetappet yevalvu kukudlulisa intshukumo kunye namandla ecamshaft kwintonga yokutyhala okanye ivalve, kwaye utyhale intonga yokutyhala okanye ivalve ukoyisa amandla omthombo wevalve. I-tappet kufuneka imelane ne-lateral force eyenziwa yi-CAM ngexesha lokusebenza kwaye idlulisele kumzimba okanye intloko ye-cylinder. Iitapethi zinokwahlulwa zibe ziitapethi zoomatshini kunye ne-hydraulic, nganye inesakhiwo sayo kunye nomsebenzi wayo:
Itappet yoomatshini : idla ngokwenziwa ngentsimbi yealloyi okanye intsimbi ephoswe ngengxubevange enokumelana nokunxiba kakuhle. Ulwakhiwo lulula kodwa ukucocwa kwevalve kufuna ukulungiswa rhoqo.
I-tappet ye-hydraulic : Isusa ngokuzenzekelayo ukucocwa kwevalvu ngaphandle kohlengahlengiso kwaye inciphisa ingxolo yothumelo. I-tappet ye-hydraulic iqulunqwe ngumzimba we-tappet, i-plunger kunye nomthombo wembuyekezo, njl., Elungiswa ngokuzenzekelayo ngoxinzelelo lweoli kunye nesenzo sentwasahlobo .
Iimeko ezithile zesicelo kunye neenzuzo kunye nokungalunganga
Itappet yoomatshini : Ulwakhiwo olulula, kodwa lufuna ukugcinwa rhoqo kunye nohlengahlengiso lokucocwa kwevalvu. Isebenza kwiimeko ezingadingi ukugcinwa okuphezulu.
i-hydraulic tappet : Isakhiwo esintsonkothileyo kodwa sinokuhlengahlengiswa ngokuzenzekelayo, sinciphise umsebenzi wokulungisa, silungele ukuthembeka okuphezulu kunye neemfuno zengxolo yendawo yesehlakalo. I-tappet ye-hydraulic ilungiswa ngokuzenzekelayo ngesenzo soxinzelelo lwe-oyile kunye nentwasahlobo, enokuphelisa ukukhutshwa kwevalve kunye nokunciphisa ingxolo yokuhambisa.
Indima yengalo yevalve rocker kunye netappet ikakhulu ibandakanya le miba ilandelayo:
Indima yetappet
Umsebenzi ophambili wetappet kukudlulisa ukutyhala kwecamshaft kwintonga yokutyhala okanye intonga yevalvu, kwaye utyhale intonga yokutyhala okanye ivalve ukoyisa amandla omthombo wevalve kunye nokuhamba. Ngexesha elifanayo, ukubethelwa kwakhona kuthwala imikhosi esecaleni eyenziwa ngokujikeleza kwecamshaft. I-tappet inokohlulwa ibe ziindidi ezimbini: i-tappet eqhelekileyo kunye ne-hydraulic tappet:
tappet eqhelekileyo : kubandakanywa i-fungus tappet, i-barrel tappet kunye ne-roller tappet. Iitapethi eziqhelekileyo ziyizakhiwo eziqinileyo kwaye azikwazi ukuphelisa ngokuzenzekelayo ukukhutshwa kwevalve, ngoko ke kuyimfuneko ukulungelelanisa ukukhutshwa kwevalve rhoqo.
I-tappet ye-hydraulic : inokuphelisa ukucocwa kwevalvu ye-injini, akukho mfuneko yokulungelelanisa ukucocwa kwevalvu, kwaye inokunciphisa ingxolo yokuhanjiswa kwendlela yevalve ye-injini. I-tappet ye-hydraulic ilungisa ngokuzenzekelayo ukukhutshwa kwe-valve ngoxinzelelo lwe-oyile kunye nesenzo sombuyekezo we-spring ukuze kuqinisekiswe uqhagamshelwano olusondeleyo phakathi kwevalve kunye ne-CAM.
Indima yengalo yerocker
Umsebenzi oyintloko wengalo ye-rocker kukugqithisa amandla ukusuka kwintonga yokutyhala okanye i-CAM ukuya kwivalve emva kokutshintsha indlela yokuyivula. Indibano yengalo ye-rocker ibandakanya ingalo ye-rocker, i-rocker arm shaft, isihlalo senkxaso, isikrufu sokulungelelaniswa kwevalve kunye namanye amalungu. Ezi nxalenye zisebenza kunye ukuqinisekisa ukuvulwa ngokuchanekileyo kunye nokuvalwa kwevalve, ngaloo ndlela ilawula inkqubo yokungena kunye nokukhupha kunye nokuqinisekisa ukusebenza okuqhelekileyo kwe-injini.
Umgaqo wokusebenza othe ngqo
Xa i-injini isebenza, i-crankshaft iqhuba i-camshaft ukuba ijikeleze kwindlela yokuhambisa, kwaye i-CAM kwi-camshaft ityhala intonga yokutyhala okanye ivalve kwi-tashet. Xa inxalenye ephakanyisiweyo ye-CAM ityhala kwi-tappet, i-tappet idlulisela amandla kwi-push rod okanye i-valve, ivula i-valve. Ngokujikeleza kweCAM, i-valve ivalwe ngokuthe ngcembe phantsi kwesenzo sentwasahlobo. Ingalo yerocker idlulisela amandla entonga yokutyhala okanye i-CAM kwivalve, iqinisekisa ukuba ivalve ivula kwaye ivale ngokuchanekileyo.
