Yintoni indibano yengalo yeroller rocker yemoto
I-automotive roller rocker arm assembly yinxalenye ebalulekileyo ye-injini valve train, equka ikakhulu ii-rocker arm arm arm, ii-rocker arm shafts kunye nee-push rods. Isebenzisa isakhiwo se-roller ukunciphisa ukungqubana kunye nokwandisa intshukumo ye-camshaft.
Umsebenzi oyintloko
Guqula intshukumo yokujikeleza ye-camshaft ibe yintshukumo ethe tye yeevalvu, lawula ukuvulwa nokuvalwa kweevalvu, kwaye ufezekise imijikelo emine yestroke yokungenisa, ukucinezelwa, ukuvelisa umbane kunye nokuphuma kwenjini.
Iimpawu zesakhiwo
Isebenzisa uyilo lwe-lever enengalo ezimbini. Isiphelo sengalo ende siqhagamshelwe kwisiqu sevalvu, kwaye isiphelo sengalo emfutshane sixhotyiswe ngesikrufu sokulungisa ukususwa kwevalvu.
Ixhotyiswe ngemijelo yeoyile yokuthambisa kunye nemingxunya yeoyile ngaphakathi ukuqinisekisa ukuthambisa okulungileyo
Intloko idla ngokuba yi-cylindrical kwaye iqengqeleka ecaleni kobuso be-valve stem xa ijika ukuze inciphise ukuguguleka
Umahluko wohlobo
Kukho iintlobo ezimbini eziqhelekileyo: ii-valve stem rocker arms kunye nee-roller rocker arms. Phakathi kwazo, i-roller rocker arm iguqula i-sliding friction ibe yi-rolling friction ngokusebenzisa ii-needle roller bearings, nto leyo enokunciphisa ukuguguleka kwaye iphucule ulawulo lwe-valve lift.
Umsebenzi we-automotive roller rocker arm assembly kukuguqula intshukumo yokujikeleza ye-camshaft ibe yintshukumo ethe tye yeevalvu, ukulawula ngokuchanekileyo ukuvulwa nokuvalwa kweevalvu, kunye nokufezekisa umsebenzi wokusasazwa kweevalvu zenjini.

Intshukumo yokujikeleza ye-camshaft iguqulwa ibe yintshukumo ethe tye yeevalvu ngesakhiwo se-lever, ukuqinisekisa ukuba iivalvu ziyavuleka kwaye zivalwe ngexesha.
Ulawulo lwevalvu ye-Youdaoplaceholder0
Ukuphucula i-valve lift curve ukuze kufezekiswe ulawulo oluchanekileyo lokungenisa kunye nokukhupha umoya kuchaphazela ngokuthe ngqo ukusebenza kakuhle kokutshaja kunye nokusebenza kakuhle kokutsha kwenjini.
Inkxaso yenkqubo ye-Youdaoplaceholder0
Njengenxalenye ephambili yesitimela sevalvu, kufuneka imelane nokutyhalwa okudluliswa yi-camshaft kunye namandla okusabela entwasahlobo yevalvu ukuqinisekisa uzinzo lwenkqubo yothumelo.
Iziphene kwi-roller rocker arm assembly yemoto zihlala zibonakala njengengxolo engaqhelekanga yenjini, amandla aphantsi, ukusetyenziswa kwepetroli okwandisiweyo kunye nezinye iimpawu. Izizathu ezithile ziquka iziphene zoyilo, ukuthambisa okungekho ngokwaneleyo, ukusebenza komthwalo omninzi kunye nezinye izinto.
Iimpawu eziqhelekileyo zempazamo
Ingxolo engaqhelekanga yentsimbi: Isandi esicacileyo sokungqongqoza kwentsimbi senzeka ngesantya esingenzi nto okanye esiphantsi, kwaye ingxolo engaqhelekanga inokuqina ngexesha lokukhawulezisa.
I-Youdaoplaceholder0 Ukulahleka kwamandla: Ukuvulwa nokuvalwa okungaqhelekanga kweevalvu kubangela ukungangeni ngokwaneleyo, okubangela ukukhawulezisa okubuthathaka kunye nokusabela okulibazisekileyo kwe-throttle.
I-Youdaoplaceholder0 Ukusetyenziswa kwepetroli okwandisiweyo : Ukusebenza kakuhle kokutsha kwehla, kwaye ukusetyenziswa kwepetroli kunokunyuka nge-10% ukuya kwi-20%.
Ubunzima bokuqalisa: Ukungasebenzi kakuhle kakhulu kunokubangela ukungaphumeleli kokuqala okanye ukulibaziseka.
Uhlalutyo lweZinto ezibangela iziphene
Isiphene soyilo lwe-Youdaoplaceholder0: Uyilo lwengalo ye-rocker kwezinye iimodeli lunengxaki yokuxinwa koxinzelelo, nto leyo enokukhokelela ekuguqukeni okanye ekuqhekekeni phantsi komthwalo omkhulu wexesha elide.
I-Youdaoplaceholder0 Ukuthambisa okungaqhelekanga : Ioyile yenjini enganelanga, isihluzi esivalekileyo okanye uxinzelelo olungaqhelekanga lwepompo, okubangela ukungqubana okomileyo phakathi kweentsimbi.
Umsebenzi we-Youdaoplaceholder0 Umthwalo ophezulu: Ukuqhuba ngesantya esiphezulu rhoqo okanye ukunyuka umthwalo onzima kwandisa umthwalo kwizinto.
Iingcebiso zokuthintela nezokuphatha
Ulondolozo oluqhelekileyo lwe-Youdaoplaceholder0: Jonga inqanaba leoyile kunye nemeko yesihluzo, kwaye usebenzise ioyile ehlangabezana nemigangatho.
I-Youdaoplaceholder0 Ziphephe iimeko zokusebenza eziqatha: Nciphisa ukuqhuba umthwalo omninzi ixesha elide kwaye uqaphele ukupholisa injini.
I-Youdaoplaceholder0 Ukugcinwa ngexesha elifanelekileyo : Xa kufunyenwe ingxolo engaqhelekanga okanye ukwehla kwamandla, jonga ngoko nangoko ivalvu evulekileyo kwaye uyitshintshe indibano ukuba kuyimfuneko.
Umgaqo wokusebenza kwe-automotive roller rocker arm assembly uxhomekeke kakhulu ekudityanisweni kwenkqubo ye-hydraulic kunye nee-ball bearings ukuze kufezekiswe ukulungiswa ngokuzenzekelayo kunye nokuthambisa kwe-valve clearance. Le yindlela ethile elandelwayo yile:
Ulwakhiwo lwesakhiwo
I-roller rocker arm assembly inee-hydraulic components (i-plunger hydraulic cylinder, i-plunger spring, i-check valve) kunye ne-ball bearing assembly (iprofayili yepleyiti yentsimbi, i-CAM roller). Phakathi kwazo, ii-hydraulic components ziqhagamshelwe kwinkqubo yokuthambisa injini nge-oyile passage, kwaye i-check valve yenziwe yibhola encinci kunye ne-compression spring.
Inkqubo yomsebenzi
Uhlengahlengiso lwesithuba se-Youdaoplaceholder0
Xa kukho ivalvu evulekileyo, i-plunger ityhalelwa ngaphandle yispring ide i-roller idibane ne-CAM. Kule ndawo, i-check valve iyavuleka, kwaye ioyile yenjini ingena kwigumbi leoyile elisezantsi ukuze ilinganise uxinzelelo, ekugqibeleni ifikelele kunxibelelwano olusondeleyo phakathi kwengalo ye-roller rocker kunye ne-CAM.
I-Youdaoplaceholder0 valve drive
Xa i-CAM ijikeleza, i-roller ilandela kwaye iqhube i-rocker arm lever ukuba ihambe. Isilinda se-hydraulic sifumana ukuthambisa okuqhubekayo ngokutshiza i-oyile yokuthambisa, ukunciphisa ilahleko yokungqubana kunye nokunciphisa ingxolo yokusebenza ngaxeshanye.
Ukulingana okuguquguqukayo kwe-Youdaoplaceholder0
Xa i-camshaft ijikeleza ukuya kwinqanaba lokuvalwa kwevalvu, ivalvu yokujonga iyavalwa emva kokuba uxinzelelo olukwisilinda ye-hydraulic lulinganisiwe, igqibezela isenzo sokubuya kwentwasahlobo yevalvu.
Ityala letyala
Ukuba uxinzelelo lweoyile aluqhelekanga okanye umgangatho weoyile awulungelelananga (njengokuba ipetroli ekumgangatho ophantsi ebangela ukuba ioyile yonakale), oko kunokukhokelela kwiingxaki ezinje ngokugqwala kwee-valve tappets kunye nokungaphumeleli kokuthambisa, okunokubangela ingxolo engaqhelekanga okanye ukulahleka kombane.
