Iyini i-car roller rocker arm assembly?
I-automotive roller rocker arm assembly iyisici esibalulekile sesitimela se-valve yenjini, esakhiwe kakhulu yizingalo ze-rocker, imiphini yengalo ye-rocker kanye nezinduku zokusunduza. Isebenzisa isakhiwo se-roller ukunciphisa ukungqubuzana nokukhulisa ukunyakaza kwe-camshaft.
Umsebenzi oyinhloko
Guqula ukunyakaza kokujikeleza kwe-camshaft kube ukunyakaza okuqondile kwamavalvu, lawula ukuvulwa nokuvalwa kwamavalvu, bese ufinyelela imijikelezo emine yokushaya yokungenisa, ukucindezela, ukukhiqizwa kwamandla kanye nokukhipha injini.
Izici zesakhiwo
Yamukela umklamo we-lever enezingalo ezimbili. Ingalo ende ixhunywe esiqwini se-valve, kanti ingalo emfushane ifakwe isikulufu sokulungisa ukulawula ukuvuleka kwe-valve.
Ifakwe iziteshi zamafutha okugcoba kanye nemigodi yamafutha ngaphakathi ukuqinisekisa ukugcotshwa okuhle
Ikhanda livame ukuklanywa ukuthi libe yi-cylindrical futhi ligoqeke ngasekugcineni kwesiqu se-valve uma lijika ukuze kuncishiswe ukuguguleka
Umehluko wohlobo
Kunezinhlobo ezimbili ezivamile: izingalo ze-valve stem rocker kanye nezingalo ze-roller rocker. Phakathi kwazo, ingalo ye-roller rocker iguqula ukungqubuzana okushelelayo kube ukungqubuzana okugoqayo ngokusebenzisa ama-needle roller bearings, okunganciphisa ukuguguleka futhi kwenze ngcono ukulawula ukuphakanyiswa kwe-valve.
Umsebenzi we-automotive roller rocker arm assembly ukuguqula ukunyakaza kokujikeleza kwe-camshaft kube ukunyakaza okuqondile kwamavalvu, ukulawula ngokunembile ukuvulwa nokuvalwa kwamavalvu, nokufeza umsebenzi wokusabalalisa amavalvu enjini.
Umsebenzi othize
Ukuguqulwa kokunyakaza kwe-Youdaoplaceholder0
Ukunyakaza kokujikeleza kwe-camshaft kuguqulwa kube ukunyakaza okuqondile kwamavalvu ngesakhiwo se-lever, okuqinisekisa ukuthi amavalvu ayavuleka futhi avalwe ngesikhathi.
Ukulawula ivalvu ye-Youdaoplaceholder0
Ukuthuthukisa ijika lokuphakamisa ivalvu ukuze kufezwe ukulawula okunembile kokungenisa kanye nokukhipha umoya kuthinta ngqo ukusebenza kahle kokushaja kanye nokusebenza kahle kokushisa kwenjini.
Usekelo lwesistimu ye-Youdaoplaceholder0
Njengengxenye eyinhloko yesitimela se-valve, idinga ukumelana nokucindezelwa okudluliswa yi-camshaft kanye namandla okusabela entwasahlobo ye-valve ukuqinisekisa ukuzinza kohlelo lokudlulisa.
Amaphutha ekuhlanganisweni kwengalo ye-roller rocker yemoto avame ukubonakala njengomsindo wenjini ongavamile, amandla anciphile, ukusetshenziswa kukaphethiloli okwandisiwe kanye nezinye izimpawu. Izimbangela ezithile zifaka phakathi amaphutha okuklama, ukugcotshwa okunganele, ukusebenza komthwalo omningi kanye nezinye izici.
Izimpawu ezivamile zamaphutha
Umsindo ongavamile wensimbi: Umsindo ocacile wokungqongqoza wensimbi uvela ngesivinini esingenzi lutho noma esiphansi, futhi umsindo ongavamile ungakhula ngesikhathi sokusheshisa.
I-Youdaoplaceholder0 Ukulahlekelwa amandla : Ukuvulwa nokuvalwa okungajwayelekile kwama-valve kuholela ekungeneni ngokwanele kokungena, okubangela ukusheshisa okubuthakathaka kanye nokusabela kwe-throttle okulibazisekile.
I-Youdaoplaceholder0 Ukusetshenziswa kukaphethiloli okwandisiwe : Ukusebenza kahle kokushisa kwehla, futhi ukusetshenziswa kukaphethiloli kunganda ngo-10% kuya ku-20%.
I-Youdaoplaceholder0 Ubunzima ekuqaliseni: Ukungasebenzi kahle okukhulu kungabangela ukwehluleka kokuqala noma ukumiswa.
Ukuhlaziywa Kwezimbangela Zamaphutha
Iphutha Lomklamo we-Youdaoplaceholder0: Umklamo wengalo ye-rocker yamamodeli athile unenkinga yokugxilisa ingqondo, okungaholela kalula ekuguqukeni noma ekuqhekekeni ngaphansi komthwalo omkhulu wesikhathi eside.
I-Youdaoplaceholder0 Ukugcotshwa okungajwayelekile : Uwoyela wenjini onganele, isihlungi esivalekile noma ingcindezi yephampu engajwayelekile, okubangela ukungqubuzana okomile phakathi kwezinsimbi.
I-Youdaoplaceholder0 Ukusebenza komthwalo ophezulu : Ukushayela ngesivinini esikhulu njalo noma ukukhuphuka umthwalo osindayo kwandisa umthwalo ezingxenyeni.
Iziphakamiso zokuvimbela nokuphatha
I-Youdaoplaceholder0 Ukulungiswa okuvamile : Hlola izinga likawoyela kanye nesimo sesihlungi, bese usebenzisa uwoyela ohlangabezana nezindinganiso.
I-Youdaoplaceholder0 Gwema izimo zokusebenza ezimbi kakhulu: Nciphisa ukushayela isikhathi eside okunemithwalo eminingi futhi unake ukupholisa injini.
I-Youdaoplaceholder0 Ukulungiswa ngesikhathi: Uma kutholakala umsindo ongavamile noma ukwehla kwamandla, hlola ngokushesha i-valve bese ushintsha i-assembly uma kudingeka.
Umgomo wokusebenza kwe-automotive roller rocker arm assembly uncike kakhulu ekuxhumaniseni uhlelo lwe-hydraulic kanye nama-ball bearings ukuze kufezwe ukulungiswa okuzenzakalelayo kanye nokugcotshwa kwe-valve clearance. Lokhu okulandelayo yindlela ethile:
Ukwakheka kwesakhiwo
I-roller rocker arm assembly iqukethe izingxenye ze-hydraulic (isilinda se-hydraulic se-plunger, i-plunger spring, i-check valve) kanye ne-ball bearing assembly (iphrofayili yepuleti lensimbi, i-CAM roller). Phakathi kwazo, izingxenye ze-hydraulic zixhunywe ohlelweni lokugcoba injini ngendlela ye-oyela, kanti i-check valve yakhiwe ibhola elincane kanye ne-compression spring.
Inqubo yomsebenzi
Ukulungiswa kwegebe le-Youdaoplaceholder0
Uma kukhona i-valve clearance, i-plunger iphushwa yi-spring kuze kube yilapho i-roller ithintana ne-CAM. Kuleli qophelo, i-check valve iyavuleka, bese uwoyela wenjini ungena ekamelweni likawoyela elingezansi ukuze ulinganisele ingcindezi, ekugcineni kufezwe ukuxhumana okuseduze phakathi kwengalo ye-roller rocker kanye ne-CAM.
I-Youdaoplaceholder0 valve drive
Uma i-CAM ijikeleza, i-roller ilandela futhi iqhube i-rocker arm lever ukuthi ihambe. Isilinda se-hydraulic sithola ukuthambisa okuqhubekayo ngokufafaza uwoyela wokugcoba, kunciphisa ukulahleka kokungqubuzana nokunciphisa umsindo wokusebenza ngasikhathi sinye.
I-Youdaoplaceholder0 equilibrium enamandla
Uma i-camshaft ijikeleza esigabeni sokuvalwa kwevalvu, ivalvu yokuhlola iyavalwa ngemva kokuba ingcindezi esilinda ye-hydraulic ilinganisiwe, iqedela isenzo sokubuya kwentwasahlobo yevalvu.
Icala lephutha
Uma ingcindezi kawoyela ingajwayelekile noma ikhwalithi kawoyela iphansi (njengophethiloli wekhwalithi ephansi obangela ukuthi uwoyela ubole), kungaholela ezinkingeni ezifana nokugqwala kwama-valve tappets kanye nokwehluleka kokugcoba, okungase kubangele imisindo engavamile noma ukulahlekelwa amandla.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
