Chii chinonzi valve rocker ruoko uye tappet
Iyo yemotokari vharafu rocker ruoko uye tappet ndizvo zvakakosha zvikamu zvemotokari injini vharafu mashandiro, uye imwe neimwe yadzo ine chaiyo basa uye maitiro. ,
Valve rocker ruoko
valve rocker arm ndiyo chikamu chakakosha cheinjini yevharuvhu, basa rayo guru nderekushanda necamshaft kuti ive nechokwadi chekuvhura nekuvhara panguva yakakodzera yevharuvhu, kuitira kupedzisa kupinza uye kupera simba. Ruoko rwe rocker chirevere chemaoko maviri chine buri repakati se fulcrum. Ruoko rupfupi rwakashongedzerwa nevhavha clearance gadziriso screw kune rimwe divi, uye ruoko rurefu rwunopihwa nearc inoshanda kumeso kusunda vharafu.
Tappet yevhavha
Basa guru retappet yevharuvhu ndere kuendesa mafambiro uye simba re camshaft kuenda kutsvimbo yekusundidzira kana vharafu, uye kusunda tsvimbo yekusundidzira kana vharafu kukunda simba revharuvhu chitubu. Iyo tappet inoda kumira kune lateral simba rinoitwa neCAM panguva yekushanda uye kuiendesa kumuviri kana cylinder musoro. Matepi anogona kukamurwa kuita mechaniki uye hydraulic tappets, imwe neimwe iine yayo chaiyo chimiro uye basa:
Mechanical tappet : kazhinji inogadzirwa nealloy simbi kana alloy cast iron ine yakanaka kupfeka kuramba. Chimiro chacho chiri nyore asi kubviswa kwevhavha kunoda kugadziriswa nguva dzose.
hydraulic tappet : Inobvisa otomatiki kubvumidzwa kwevharuvhu pasina kugadzirisa uye inoderedza ruzha rwekutapurirana. Iyo hydraulic tappet inoumbwa ne tappet body, plunger uye chitubu chemuripo, nezvimwewo, iyo inogadziriswa otomatiki nekudzvanywa kwemafuta uye kuita kwechirimo.
Yakananga mashandisirwo ezviitiko uye zvakanakira nekuipira
Mechanical tappet : chimiro chakareruka, asi chinoda kugara uchigadzirisa uye kugadzirisa kwevhavha clearance. Inoshanda kune zviitiko zvisingadi kugadziriswa kwepamusoro.
hydraulic tappet : dhizaini yakaoma asi inogona kugadziridzwa otomatiki, kuderedza basa rekugadzirisa, yakakodzera kuvimbika kwepamusoro uye zvinoda ruzha rwechiitiko. Iyo hydraulic tappet inogadziridzwa otomatiki kuburikidza nekuita kweoiri kumanikidza uye chitubu, izvo zvinogona kubvisa valve clearance uye kuderedza kutapurirana ruzha.
Basa revhavha rocker ruoko uye tappet rinonyanya kusanganisira zvinotevera zvinhu:
Basa retappet
Basa guru retappet ndere kuendesa kupinza kwe camshaft kune push rod kana valve rod, uye kusunda tsvimbo yekusundidzira kana vharafu kukurira simba revharuvhu chitubu uye kufamba. Panguva imwecheteyo, iyo tappings inotakurawo lateral masimba anoitwa ne camshaft kutenderera. Iyo tappet inogona kukamurwa kuita mhando mbiri: yakajairika tappet uye hydraulic tappet:
yakajairika tappet : kusanganisira fungus tappet, barrel tappet uye roller tappet. Matepi akajairwa zvimiro zvakaomarara uye haakwanise kubvisa otomatiki kubviswa kwevhavha, saka zvinodikanwa kugadzirisa kubvumidzwa kwevhavha nguva nenguva.
hydraulic tappet : inogona kubvisa kubvumidzwa kwevhavha yeinjini, hapana chikonzero chekugadzirisa kubvumidzwa kwevhavha, uye inogona kuderedza ruzha rwekutapurirana kweinjini yevharuvhu. Iyo hydraulic tappet inogadzirisa otomatiki kubviswa kwevhavha kuburikidza nekumanikidza kweoiri uye kuita kwechitubu chekubhadhara kuti ive nechokwadi chekubatana kwepedyo pakati pevhavha neCAM.
Basa rerocker arm
Basa guru reruwoko rwedombo nderekupfuudza simba kubva kutsvimbo yekusundidzira kana CAM kuenda kuvharuvhu mushure mekushandura nzira kuti ivhure. Iyo rocker arm assembly inosanganisira rocker arm, rocker arm shaft, chigaro chekutsigira, valve clearance gadziriso screw uye zvimwe zvikamu. Zvikamu izvi zvinoshanda pamwechete kuti ive nechokwadi chekuvhura uye kuvhara kwakaringana kwevhavha, nekudaro kudzora kupinza uye kupera simba uye kuve nechokwadi chekushanda kwakajairika kweinjini.
Yakananga kushanda musimboti
Kana injini iri kushanda, crankshaft inotyaira camshaft kuti itenderere kuburikidza nemuchina wekutapurirana, uye CAM iri pacamshaft inosundidzira tsvimbo yekusundidzira kana vharafu kuburikidza ne tashet. Kana chikamu chakasimudzwa cheCAM chikasunda chinopesana ne tappet, iyo tappet inotamisa simba kune yekusundidzira tsvimbo kana vharafu, ichivhura vharuvhu. Nekutenderera kweCAM, valve inovharwa zvishoma nezvishoma pasi pechiito chechirimo. Ruoko rwe rocker runoendesa simba retsvimbo yekusundidzira kana CAM kuvharuvhu, kuve nechokwadi kuti vharafu inovhura uye inovhara nemazvo.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
