Genuine Original forged camshaft yamagalimoto a chery

The camshaft adjuster ndi cam deflection control valve, yomwe ndi valavu yapakona, yomwe imapangidwa ndi makina opangira magetsi a ngodya ndi eccentric hemispherical valve. The actuator amatenga dongosolo Integrated, ndi actuator magetsi ali anamanga servo dongosolo.

Mfundo Yofunika: Sinthani nthawi yotsegulira ma valve olowetsa ndi kutulutsa molingana ndi zosowa za injini. Injini ikakhala ndi katundu wambiri, chosinthira cha camshaft chimagwiritsidwa ntchito kukhathamiritsa mbali ya valve yolumikizana molingana ndi liwiro la injini, kuti apereke mpweya wabwino kwambiri kuchipinda choyaka ngati n'kotheka, kuti akwaniritse mphamvu yayikulu ndi ngodya yolumikizirana, kuti apereke chipinda choyaka moto momwe angathere Mpweya watsopano kuti ukwaniritse mphamvu yayikulu komanso torque.

Camshaft ndi gawo la injini ya pistoni. Ntchito yake ndikuwongolera kutsegula ndi kutseka kwa ma valve. Ngakhale liwiro la camshaft mu injini zinayi za sitiroko ndi theka la crankshaft (liwiro la camshaft mu injini ya sitiroko ziwiri ndi lofanana ndi la crankshaft), nthawi zambiri liwiro lake limakhala lalitali kwambiri ndipo limayenera kukwera. kukhala ndi torque yayikulu. Choncho, mapangidwewo ali ndi zofunika kwambiri pa mphamvu ndi kuthandizira pamwamba pa camshaft, ndipo zinthu zake nthawi zambiri zimakhala zitsulo zamtengo wapatali kapena zitsulo za alloy. Chifukwa lamulo la kayendetsedwe ka valve limagwirizana ndi mphamvu ndi machitidwe a injini, mapangidwe a camshaft amatenga gawo lofunika kwambiri pakupanga injini.
Thupi lalikulu la camshaft ndi ndodo ya cylindrical yokhala ndi kutalika kofanana ndi banki ya silinda. Makamera angapo ali ndi manja kuti ayendetse valavu. Kamshaft imathandizidwa mu dzenje lokhala ndi camshaft kudzera m'magazini ya camshaft, kotero kuchuluka kwa magazini a camshaft ndi chinthu chofunikira chomwe chimakhudza kuuma kwa chithandizo cha camshaft. Ngati kuuma kwa camshaft sikukwanira, kupindika kudzachitika panthawi yogwira ntchito, zomwe zimakhudza nthawi ya valve.
Mbali ya ngamira ndi yooneka ngati dzira. Zapangidwa kuti zitsimikizire kudya kokwanira komanso kutha kwa silinda. Kuphatikiza apo, poganizira kukhazikika komanso kusalala kwa injini, valavu silingakhale ndi mphamvu zambiri chifukwa cha kuthamangitsa komanso kuthamangitsa njira yotsegulira ndi kutseka, apo ayi zingayambitse kuwonongeka kwakukulu kwa valavu, phokoso lambiri kapena zina zazikulu. zotsatira. Chifukwa chake, kamera imakhudzana mwachindunji ndi mphamvu, torque linanena bungwe ndi kuthamanga kusalala kwa injini.
Zolakwika zambiri za camshaft zimaphatikizapo kuvala kwachilendo, kumveka kwachilendo komanso kusweka. Kuvala kwachilendo kumachitika nthawi zambiri kusanamveke bwino komanso kusweka.
(1) Camshaft ili pafupi kumapeto kwa makina opangira mafuta a injini, kotero kuti mafutawo alibe chiyembekezo. Ngati kukakamiza kwamafuta a pampu yamafuta sikukwanira chifukwa chanthawi yayitali yogwira ntchito, kapena mafuta opaka mafuta sangathe kufika pa camshaft chifukwa cha kutsekeka kwa njira yamafuta opaka mafuta, kapena mafuta opaka mafuta sangathe kulowa pachilolezo cha camshaft chifukwa chakumangika kwambiri. pazitsulo zomangira za chivundikiro chonyamula, camshaft idzavala mosadziwika bwino.
(2) Kuvala kwachilendo kwa camshaft kumawonjezera kusiyana pakati pa camshaft ndi mpando wonyamula, ndipo camshaft idzasuntha axially, zomwe zimapangitsa kuti phokoso likhale losazolowereka. Kuvala kwachilendo kumawonjezeranso kusiyana pakati pa kamera yoyendetsa galimoto ndi tappet ya hydraulic, ndipo kamerayo idzagundana ndi tappet ya hydraulic, zomwe zimabweretsa phokoso losazolowereka.
(3) Zolakwa zazikulu monga camshaft fracture nthawi zina zimachitika. Zomwe zimayambitsa ndi kugawanika kwa ma tappet a hydraulic kapena kuvala kwambiri, mafuta osakwanira bwino, camshaft yabwino komanso kusweka kwa zida za camshaft.
(4) Nthawi zina, kulephera kwa camshaft kumayambitsidwa ndi zinthu zaumunthu, makamaka pamene camshaft siinasonkhanitsidwe molondola panthawi yokonza injini. Mwachitsanzo, pochotsa chivundikiro cha camshaft, chigwetseni ndi nyundo kapena kuchipukuta ndi screwdriver, kapena kuyika chivundikirocho pamalo olakwika, zomwe zimapangitsa kuti pakhale kusiyana pakati pa chivundikirocho ndi mpando wonyamula, kapena kulimbitsa mphamvu. mabawuti omangirira a chivundikirocho ndi chachikulu kwambiri. Mukayika chivundikirocho, tcherani khutu ku muvi wolowera, nambala yamalo ndi zizindikiro zina pamwamba pa chivundikirocho, ndikumangitsani zomangira za chivundikirocho ndi wrench ya torque motsatana ndi torque yomwe yatchulidwa.
