Chii chinonzi valvu rocker arm uye tappet?
Ruoko rwemavharuvhu emota netappet ndizvo zvikamu zvakakosha zvevharuvhu yeinjini yemota, uye chimwe nechimwe chazvo chine basa racho uye mhedzisiro yacho.
Ruoko rwerocker yevharuvhu
Ruoko rwe rocker rwevharuvhu chikamu chakakosha chevharuvhu yeinjini, basa rayo guru nderekushanda ne camshaft kuona kuti vharuvhu inovhurwa nekuvharwa nenguva, kuitira kuti intenation ne exhaust process zvipedzwe. Ruoko rwe rocker rune maoko maviri neburi repakati re shaft se fulcrum. Ruoko rupfupi rwakashongedzwa nesikuruu yekugadzirisa valvu kune rumwe rutivi, uye ruoko rurefu rune arc working face yekusunda vharuvhu.
Tapeti yevharuvhu
Basa guru revharuvhu tappet nderekufambisa kufamba nesimba recamshaft kuenda kutsvimbo yekusundidzira kana vharuvhu, uye kusundidzira tsvimbo yekusundidzira kana vharuvhu kuti ikunde simba rechitubu chevharuvhu. Tappet inofanira kutsungirira simba rerutivi rinoshandiswa neCAM panguva yekushanda uye kuiendesa kumutumbi kana musoro wesilinda. Tappet dzinogona kukamurwa kuita matepi emakanika uye ehydraulic, rimwe nerimwe riine chimiro charo nebasa rayo:
Tapeti yemakanika: inowanzogadzirwa nesimbi yesimbi kana simbi yakakandwa ine simba rekudzivirira kubvaruka. Chimiro chacho chiri nyore asi nzvimbo yekuvhara vharuvhu inofanira kugadziriswa nguva nenguva.
Tappet yehydraulic: Inobvisa otomatiki kuvhurika kwevharuvhu pasina kugadziriswa uye inoderedza ruzha rwekutumira. Tappet yehydraulic inoumbwa nemuviri wetappet, plunger uye chitubu chekutsiva, nezvimwewo, izvo zvinogadziriswa otomatiki nekumanikidzwa kwemafuta uye kushanda kwechitubu.
Mamiriro chaiwo ekushandisa uye zvakanakira uye zvakaipa
Tappet yemakanika: chimiro chiri nyore, asi chinoda kugadziriswa nguva nenguva uye kugadziriswa kwekubviswa kwevharuvhu. Izvi zvinoshanda kune zviitiko zvisingade kugadziriswa kwakanyanya.
Tappet yehydraulic: chimiro chakaoma asi chinogona kugadziriswa otomatiki, kuderedza basa rekugadzirisa, chakakodzera kuvimbika kwakanyanya uye zvinodiwa neruzha panzvimbo yacho. Tappet yehydraulic inogadziriswa otomatiki kuburikidza nekushanda kwekumanikidzwa kwemafuta nechitubu, izvo zvinogona kubvisa kucheneswa kwevharuvhu uye kuderedza ruzha rwekutumira.
Basa reruoko rwevharuvhu rwerocker netappet rinosanganisira zvinhu zvinotevera:
Basa remutambi wetappet
Basa guru retappet nderekufambisa simba recamshaft kuenda kutsvimbo yekusundidzira kana vharuvhu, uye kusundidzira simba re push rod kana vharuvhu kuti ikunde simba rechitubu chevharuvhu uye ifambe. Panguva imwe chete, kusundidzira kunotakurawo simba repadivi rinoitwa nekutenderera kwecamshaft. Tappet inogona kukamurwa kuita mhando mbiri: tappet yakajairika uye hydraulic tappet:
Tappet yakajairika : kusanganisira fungus tappet, barrel tappet uye roller tappet. Tappet dzakajairika dzakasimba uye hadzigone kubvisa valvu yega, saka zvinodikanwa kugadzirisa valvu nguva nenguva.
Tappet ye hydraulic : inogona kubvisa kuvhurika kwevharuvhu yeinjini, hapana chikonzero chekugadzirisa kuvhurika kwevharuvhu, uye inogona kuderedza ruzha rwekutumira kwemuchina wevharuvhu yeinjini. Tappet ye hydraulic inogadzirisa yega kuvhurika kwevharuvhu kuburikidza nekumanikidzwa kwemafuta uye kushanda kwechitubu chinotsiva kuti ive nechokwadi chekuti vharuvhu neCAM zviri pedyo.
Basa reruoko rwemutambi werocker
Basa guru reruoko rwerocker nderekufambisa simba kubva patsvimbo yekusunda kana CAM kuenda kuvharuvhu mushure mekuchinja divi kuti rivhurike. Rocker arm assembly inosanganisira ruoko rwerocker, shaft yeruoko rwerocker, chigaro chekutsigira, sikuruu yekugadzirisa clearance yevharuvhu nezvimwe zvikamu. Zvikamu izvi zvinoshanda pamwe chete kuti zvive nechokwadi chekuvhurwa nekuvharwa kwakarurama kwevharuvhu, nokudaro zvichidzora maitiro ekupinda nekubuda kwemhepo uye kuona kuti injini inoshanda zvakanaka.
Nheyo chaiyo yekushanda
Kana injini iri kushanda, crankshaft inotyaira camshaft kuti itenderere kuburikidza ne transmission mechanism, uye CAM iri pa camshaft inosundira push rod kana valvu kuburikidza ne tashet. Kana chikamu chakasimudzwa che CAM chikasundira tappet, tappet inotamisa simba ku push rod kana valvu, ichivhura valvu. Nekutenderera kwe CAM, valvu inovharwa zvishoma nezvishoma pasi pekushanda kwechitubu. Rocker arm inotumira simba re push rod kana CAM kuvhavu, ichiva nechokwadi chekuti vhavu inovhurika uye inovhara nemazvo .
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
