Ukusebenza kahle kwayo yonke injini yemoto kuncike ngqo esimweni se-camshaft. Ngisho nokungasebenzi kahle kancane kwalo mshini wokusabalalisa igesi kuthinta izici zamandla nokudonsa kweyunithi yamandla, ingasaphathwa eyokunyuka kokusetshenziswa kukaphethiloli kanye nokuhlukana okuhlobene. Kulesi sihloko sizokhuluma ngenjongo camshaft, isimiso sokusebenza kwayo, ukungasebenzi main futhi kanjani ukuqeda kwabo usebenzisa isibonelo imoto Vaz 2107.

I-Camshaft VAZ 2107

I-camshaft iyisici esiyinhloko somshini wokusabalalisa igesi wenjini yemoto. Lena ingxenye yensimbi yonke, eyenziwe ngendlela yesilinda enamajenali aphethe kanye namakhamera abekwe kuwo.

Amakhamera nezintamo zibekwe ku-camshaft

Injongo

I-shaft yesikhathi isetshenziselwa ukulawula izinqubo zokuvula nokuvala ama-valve emakamelweni avuthayo enjini. Ngamanye amazwi, ivumelanisa imijikelezo yokusebenza yeyunithi yamandla, ngokuhamba kwesikhathi ivumela ingxube ye-fuel-air emagumbini omlilo futhi ikhiphe amagesi e-exhaust kuwo. I-camshaft ye "sevens" iqhutshwa ukujikeleza kwenkanyezi yayo (igiya), exhunywe ngeketango egiyeni le-crankshaft.

Uphi lapho

Ngokuya ngomklamo wenjini, i-shaft yesikhathi ingaba nendawo ehlukile: phezulu nangaphansi. Endaweni yayo ephansi, ifakwe ngqo ku-cylinder block, futhi phezulu - ekhanda le-block. Ku-"sevens" i-camshaft itholakala phezulu kwekhanda le-cylinder. Leli lungiselelo, okokuqala, lenza kutholakale kalula ukulungiswa noma ukushintshwa, kanye nokulungisa ukucaciswa kwama-valve. Ukuze ufinyelele ku-shaft yesikhathi, kwanele ukususa isembozo se-valve.

Isimiso sokusebenza

Njengoba sekushiwo, i-camshaft ishayelwa igiya le-crankshaft. Ngesikhathi esifanayo, isivinini sokujikeleza kwayo, ngenxa yobukhulu obuhlukene bamagiya okushayela, sincishiswa ncamashi ngesigamu. Umjikelezo wenjini ogcwele wenzeka ngokushintshashintsha okubili kwe-crankshaft, kodwa i-timing shaft yenza ukuphenduka okukodwa kuphela, lapho ikwazi khona ukuvumela ingxube ye-fuel-air ibe amasilinda bese ikhulula amagesi e-exhaust.

Ukuvulwa (ukuvalwa) kwama-valve ahambisanayo kuqinisekiswa isenzo samakhamera kuma-valve lifters. Kubukeka kanje. Lapho i-shaft ijikeleza, uhlangothi oluphumayo lwekhamera lucindezela i-pusher, edlulisela amandla ku-valve egcwele intwasahlobo. Lesi sakamuva sivula iwindi lokungena kwengxube evuthayo (i-outlet of gases). Lapho ikhamera iphenduka ngokuqhubekayo, i-valve ivala ngaphansi kwesenzo sentwasahlobo.

Amavalvu avuleka lapho izingxenye eziphumile zamakhamera zicindezelwa kuwo.

Izici ze-camshaft Vaz 2107

Ukusebenza shaft isikhathi Vaz 2107 kunqunywa nemingcele ezintathu eziyinhloko:

• ububanzi bezigaba buyi-232^о;
• i-valve yokuphuza - 40^о;
• I-valve yokukhipha - 42^о.

Inombolo yamakhamera ku-camshaft ihambisana nenani lama-valve okungenisa kanye nokukhipha. "Eziyisikhombisa" zineziyisishiyagalombili zazo - ezimbili kumasilinda amane.

Kungenzeka yini ukwandisa amandla injini Vaz 2107 ngokufaka enye camshaft

Mhlawumbe, wonke umnikazi "eziyisikhombisa" ufuna injini yemoto yakhe ukusebenza hhayi kuphela ngaphandle kokuphazamiseka, kodwa futhi ukusebenza kahle esiphezulu. Ngakho-ke, ezinye izingcweti zizama ukushuna amayunithi amandla ngezindlela ezihlukahlukene. Enye yalezi zindlela ukufaka enye, i-camshaft "ethuthukisiwe" ngaphezulu.

Ingqikithi yokushuna

Ngokwethiyori, kungenzeka ukwandisa izinkomba zamandla zeyunithi yamandla ngokwandisa ububanzi bezigaba kanye nokuphakama kokuphakama kwe-valve yokungena. Inkomba yokuqala inquma isikhathi lapho i-valve yokungena izovuleka, futhi ivezwe nge-engeli yokujikeleza kwe-shaft yesikhathi. Kwaba “bayisikhombisa” bangama-232^о. Ubude bokuphakama kwevalvu yokudonsa bunquma indawo yembobo lapho ingxube ye-fuel-air izonikezwa khona ekamelweni elivuthayo. Ukuze Vaz 2107, kuba 9,5 mm. Ngakho-ke, futhi, ngombono, ngokunyuka kwalezi zinkomba, sithola umthamo omkhulu wengxube evuthayo kumasilinda, okungathinta ngempela amandla eyunithi yamandla.

Kungenzeka ukwandisa ububanzi bezigaba kanye nokuphakama kwe-valve yokungenisa ngokushintsha ukumiswa kwamakhamera ahambisanayo we-shaft yesikhathi. Njengoba umsebenzi onjalo awukwazi ukwenziwa egaraji, kungcono ukusebenzisa ingxenye eqediwe evela kwenye imoto ukulungisa okunjalo.

Camshaft kusukela "Niva"

Kukhona imoto eyodwa kuphela, i-camshaft efanelekayo "eziyisikhombisa". Lena i-VAZ 21213 Niva. I-timing shaft yayo inobubanzi besigaba esingu-283^о, futhi i-valve yokungena ingu-10,7 mm. Ingabe ukufakwa kwengxenye enjalo injini ye-VAZ 2107 kunikeza okuthile empeleni? Ukuzijwayeza kubonisa ukuthi yebo, ukuthuthukiswa okuncane ekusebenzeni kweyunithi yamandla kuyaphawulwa. Ukwanda kwamandla cishe kumalitha ama-2. nge., kodwa ngesivinini esiphansi kuphela. Yebo, "eziyisikhombisa" ziphendula kancane kancane ekucindezeleni i-accelerator pedal ekuqaleni, kodwa ngemva kokuthola umfutho, amandla ayo ayafana.

Ama-camshaft ezemidlalo

Ngaphezu kwe-shaft yesikhathi evela ku-Niva, ku-VAZ 2107 ungakwazi futhi ukufaka enye yemishini eyenziwe ngokukhethekile "ezemidlalo" zokulungiswa kwamayunithi amandla. Izingxenye ezinjalo zikhiqizwa amabhizinisi amaningi asekhaya. Izindleko zabo zisukela kuma-ruble angama-4000-10000. Cabanga ngezici zama-camshafts anjalo.
