Kusimudza mavharuvhu muinjini dzinopisa mukati - kutsiva kwevharuvhu kunodiwa riini?

Yese inosimudza vharafu ine basa rekubhadharira kubviswa kwevharuvhu. Izvi zvinoderedza chinhambwe pakati pepamusoro pepushrod uye shaft cam. Iine simba rinogadzirisa panguva yekuvhura kwevhavha uye kuvhara kwavo kwakarurama. Naizvozvo, iyo inosimudza vharafu inofanirwa kunge iri mukushanda mamiriro uye inopa fekitori vharafu kubvumidzwa mune mukati meinjini dzinopisa. Tsvaga kuti inoshanda sei uye paunoona chimwe chinhu chisina kumira zvakanaka pairi uye inoda kutsiviwa. Ona kana uchikwanisa kutsiva chinhu ichi pachako!

Mavharuvhu anosimudza uye dhizaini yawo

Makapu evhavha - sekudanwa kunoitwa zvinhu izvi - zvine dhizaini iri nyore. Kazhinji dzinosanganisira:

• dzimba;
• pisitoni;
• makamuri akaderera uye akakwirira;
• cheki vharafu;
• pad mafuta;
• zvitubu.

Uku ndiko dhizaini yema hydraulic valve lifters ayo anoshandiswa mumainjini mazhinji anogadzirwa parizvino. Kubatsira kwavo kusingarambiki ndiko kushaikwa kwekuchengetedza. Nekudaro, kune vanogadzira tappets vasina hydraulics, uye vanofanirwa kugadziridzwa nguva nenguva. Izvi zvingave zvisingabatsiri, asi sevhavha yakadaro inosimudza ichava yakanyanya nyore uye yakasimba.

Hydraulic valve lifters - musimboti wekushanda

Ko hydraulic pusher inoshanda sei muinjini? Kudzvinyirirwa kwecamshaft cam pamusoro petappet kunoita kuti cheki valve ivhare uye kuwedzera kudzvinyirira. Kutenda kune izvi, kubviswa kwevhavha kunobviswa, uye valve inogona kushanda panguva yakakodzera. Kana shaft cam yadzikiswa uye isingachabata pusher, valve inovhura uye kudzvanywa mumakamuri kunoenzana. Mushure maizvozvi, valve inogona kuvharwa uye kudzokera kunzvimbo yayo yepakutanga.

Hydrodistributor tappet - inogona kukuvara here?

Ko hydraulic lifter ingakundikana here? Zvirokwazvo hongu, ndosaka kutsiva nguva dzose kuchidikanwa. Ivhavha inosimudza iyo inoshandisa mafuta einjini inogona kutadza kana yakasvibiswa. Ichi chikamu chidiki chinoiswa pasi pemitoro yakakosha uye tembiricha inoshanduka, uye nekudaro inoda kutarisirwa mukushanda. Zvakakodzera kushandisa akanakisa emhando yemafuta enjini uye achiachinja nguva nenguva. Kunyange tsvina shoma inogona kuvhara migero mumapusher uye kuvhara kushanda kwavo.

Chii Chinokonzera Valve Tappet Matambudziko?

Uye zvakare, nekufamba kwenguva, iwo anosundidzira eiyo hydraulic distributors anopera. Piston, chitubu, kana mapedhi emafuta anogona kupera uye oiri yeinjini inotanga kupinda mukamuri rinopisa. Kubhadharwa kwevhavhavha yemvumo inogonawo kusashanda, sezvinoonekwa kubva pane maitiro ejini. Kuti unzwisise izvi, zvakakosha kutsanangura kuti chii chinonzi valve clearance.

Valve clearance muinjini dzinopisa mukati

Iyo yekusimudza vharafu yakabatana kune gap. Sei makamera ejini asina kukwanisa kubata zvakananga uye kutonga mavharuvhu? Izvi hazvigoneki nekuda kwezvikonzero zvakawanda. Imwe yeanonyanya kukosha maitiro esimbi pasi pesimba rekushanda tembiricha. Zvikamu zvenguva yemotokari zvinowedzera kana zvapiswa, izvo zvinoderedza chinhambwe pakati pezvikamu zvega. Kudzora vharafu kuvhura uye nguva yekuvhara kunoda michina ine inooneka valve clearance inogona kuenzana sezvo injini inodziya uye kutonhora pasi. Zvikasadaro, panguva yekushanda kweiyo unit, mavharuvhu aisavhara uye kubonderana nemapistoni kana kudonha kwekumanikidza kunogona kuitika.

Yakakuvadzwa mavharuvhu emota - zviratidzo zvekupfeka

Kana iwe wakakuvadza kana kupfeka matepi mumotokari yako, zviratidzo zvinoonekwa mutsika yekushanda kweinjini. Pachisina basa, kana injini ichitonhora, kushanda kwechikwata kunogona kuvhiringidzika. Iyo revs haizogara iripo uye kudzvanywa kunodonha, nekuda kwekudiki diki kubvumidzwa kwevharuvhu. Somugumisiro, mavharuvhu haavhare, iyo inonzwa pakarepo nenzira yekuderera kwemagetsi emotokari. Kuwedzera kune yakawandisa clearance, iyo valve yekusimudza inogona zvakare kukonzera yakawandisa clearance. Ipapo iwe unonzwa simbi inogogodza panguva yekushanda. Kana zvidhinha zvichipisa, zvinomira sezvo kuwedzera kwesimbi kunobvisa kutamba kwakanyanyisa.

Nzira yekutarisa hydraulic lifters mumotokari?

Kazhinji zvinhu izvi hazvikundike kamwe kamwe, asi zvishoma nezvishoma zvinorasikirwa nemidziyo yavo. Naizvozvo, mutyairi asina ruzivo rwokuzviwanira anogona kusanzwa kana kuona shanduko mukushanda kweinjini. Nekudaro, zvinobatsira kuona kuti injini inotonhora inoshanda sei:

• kana ichichengetedza shanduko yakagadzikana;
• pane dambudziko rekumanikidzana;
• pane musiyano wakasiyana mukushanda pane inotonhora uye inodziya injini;
• inoita chero mimwe mitsindo mushure mekutanga.

Valve lifter - mutengo wezvikamu zvakasara uye kutsiva

Marii inodhura kutsiva hydraulic lifters? Mutengo wechikamu chimwe hauna kunyanya kukwira. Mune yakakurumbira injini dzedhiziri, chinhu chakadaro chinogona kudhura kubva kune mashoma kusvika akati wandei zlotys chimwe nechimwe. Rangarira, zvisinei, kuti kazhinji kutsiva kunobata zvikamu zvese, uye kwete, semuenzaniso, 2 kubva pa8 kana 16. Imwe valve pusher inosarudzwa kune imwe valve, saka kana, semuenzaniso, pane gumi nematanhatu mumusoro, ipapo 16 pushers inoda kutengwa muchitoro. Mukuwedzera, iwe zvakare bvisa gasket pasi pevhavhavhavhavhavha, iyo inodhura mamwe gumi zlotys. A good mechanic anozopawo zano rekuchinja injini mafuta. Nokudaro, zvinhu zvose pamwe chete nebasa zvinogona kusvika kumuganhu we800-100 euros.

Kuzvitsiva kwevasimudza mavharuvhu

Zvinowanzoita zvakanaka kutsiva mapusher mumashopu akapupurirwa. Zvechokwadi, iwe unogona kuzviita iwe pachako uye hapana huzivi hukuru mune izvi, asi iwe unoda kuva neruzivo rwakawanda pamusoro pekugadzirwa uye kushanda kwejini. Kana iyo valve lifter yakakuvadzwa, zvinodikanwa kubvisa chivharo chevhavha uye kusunungura camshaft (kana shafts). Iyo disassembly pachayo haina kunyanya kuoma, asi kuisa zvakare zvinhu izvi munzvimbo chaiyo inogona kuve dambudziko kune hobbyist.

Valve lifter isina hydraulic backlash muripo

Dzimwe Honda neRenault injini dzine mechanically inogadziriswa valve clearance. Iyo tappet yevharuvhu haina kuzadzwa nemafuta, uye kushanda kwayo kunobva pane yakakosha mahwendefa kana zvinhu zvakasungirirwa ne screws. Iyo gap inogadziriswa uchishandisa mamwe mahwendefa kana yekunzwa geji iyo iwe yaunogona kutarisa kureba. Kune mamwe mayuniti emagetsi, basa haridi kudzokororwa kakawanda (kazhinji yega yega 60-000 km). Zvisinei, munyaya yeinjini dzinomhanya pane gasi, dzimwe nguva zvakakosha kugadzirisa gap 100 nguva kakawanda! Uye izvi zvinoda kunenge kubviswa kwegore negore kwechifukidziro uye kugadziriswa kwemagetsi evhavha.
