I-Schwing Drive Slewing Lever

Ukuhlanganiswa kwengalo ye-rocker yethula ingxube evuthayo (noma umoya omusha) kusilinda; bese icindezela ingxube evuthayo (noma umoya omusha) ku-cylinder, bese ithungela ingxube evuthayo lapho ukucindezela kuseduze nendawo yokugcina (noma ijova idizili ku-cylinder ukuze wenze ingxube evuthayo futhi uyishise); ingxube evuthayo iyathungela futhi iyasha, futhi ukunwetshwa kuphushela ipiston phansi ukuze kuzuzwe umsebenzi wangaphandle; ekugcineni, igesi yokukhipha ngemva kokusha iyakhishwa. Okusho ukuthi, ukungena komoya, ukucindezelwa, umsebenzi, ukukhipha izinqubo ezine. Iphinde ibe umthombo wamandla weloli

Izindlela zokubhuleka injini zifaka i-exhaust braking, i-air release braking kanye ne-compression release braking. Injini ithatha imodi yokukhishwa kwe-braking, futhi imodi yayo yokusebenza imi kanje:

Uma kungekho ukubhuleka, i-brake solenoid valve iyacishwa futhi ezinye izingxenye azikwazi ukugcwaliswa ngamafutha. Lapho injini igijima ifika endaweni yomphathi wamabhuleki (okungukuthi, lapho ipiston iseduze nendawo ephezulu efile), ibhulokhi ephezulu yevalvu yokukhipha umoya idinga kuphela ukunqoba amandla asentwasahlobo ku-plunger. Ngalesi sikhathi, i-boss brake ku-camshaft ayisebenzi futhi ngeke iphushe i-valve yokukhipha umoya. Injini isebenza ngokujwayelekile.

Isakhiwo se-exhaust rocker arm assembly: lapho kudingeka ibhuleki, vula iswishi yebhuleki lenjini, cindezela i-pedal yebhuleki, bese i-ECU ilawula isistimu kaphethiloli ukuze iyeke ukuhlinzeka uwoyela. Ngalesi sikhathi, i-valve ye-brake solenoid ivuliwe futhi ivuliwe, futhi uwoyela ophuma ephasejini likawoyela elisizayo ku-rocker arm shaft uvala umzila wokungenisa uwoyela ku-rocker arm bushing kanye nephaseji likawoyela elisizayo lengalo ye-rocker, bese lingena i-brake plunger chamber ye-brake; lapho amafutha ekamelweni lokubopha efinyelela ukucindezela okuthile, i-plunger ilawulwa ukuze ikhuphuke, futhi i-valve yokuhlola ivaliwe, ukuze igumbi le-brake ligcwaliswe ngamafutha. Ngenxa yokuthi uwoyela wenjini awuthinteki, lapho injini igijima ifika lapho ibhuleki khona (okungukuthi, lapho ipiston iseduze nendawo ephezulu efile), umphathi wamabhuleki ku-camshaft uphakamisa i-exhaust valve rocker roller, kanye ne-exhaust yamabhuleki. i-valve top block iphusha i-valve yokukhipha umoya ngaphansi kwamandla e-brake plunger exhaust valve rocker arm ukuze ikhiphe ingxenye yegesi enomfutho ophezulu. Lapho i-piston yehla, i-valve yokukhipha umoya iyavaleka, futhi injini isesimisweni sokushayela kuyo yonke imoto Ishayelwa ukwenza umsebenzi ongemuhle (okulingana nengaphezulu le-vacuum ye-piston), ukuze kuzuzwe ukucindezelwa kwenjini, ukukhulula. ibhuleki. Uma ijubane lenjini liphezulu, amandla okubhuleka aba makhulu.
