Schwing Drive Slewing Lever

Iyo yekutora rocker arm assembly inopinza musanganiswa unopisa (kana mweya mutsva) mucylinder; wobva wadzvanya musanganiswa unopisa (kana mweya mutsva) muhumburumbira, uye unobatidza musanganiswa unopisa kana kudzvanywa kwave pedyo nepanoperera (kana kubaya dhiziri muhumburumbira kuti igadzire musanganiswa unobvira nekuibatidza); musanganiswa unopisa unobatidza nekupisa, uye kuwedzera kunosundira piston pasi kuti iwane basa rekunze; pakupedzisira, gasi rekubuda mushure mekupisa rinobudiswa. Ndiko kuti, kupinza kwemhepo, kumanikidza, kushanda, kupedza maitiro mana. Ndiko zvakare kunobva simba rerori

Nzira dzemabhureki einjini dzinosanganisira exhaust braking, air release braking uye compression release braking. Injini inotora compression kusunungurwa braking mode, uye maitiro ayo ekushanda ndeaya anotevera:

Kana pasina mabhureki, bhureki solenoid valve inodzimwa uye zvimwe zvikamu hazvigone kuzadzwa nemafuta. Kana injini ichimhanya ichienda kunzvimbo yemukuru webhureki (ndiko kuti, kana piston iri padyo nepamusoro penzvimbo yakafa), iyo bhuroka repamusoro revharuvhu rekuburitsa rinongoda kukunda simba rechirimo mune plunger. Panguva ino, mukuru webhureki pane camshaft haashande uye haasundire vharafu yekupedza. Injini inoshanda zvakajairika.

Chimiro che exhaust rocker arm assembly: kana ichidiwa braking, batidza injini brake switch, dzvanya brake pedal, uye ECU inodzora iyo mafuta system kumisa kugovera mafuta. Panguva ino, bhureki solenoid valve inobatidzwa uye yakavhurwa, uye mafuta kubva muchikamu cheoiri chekubatsira mune rocker arm shaft inovhara iyo inopinza mafuta parocker arm bushing uye yekuwedzera mafuta nzira yerocker ruoko, uye inopinda mukati. akapwanya plunger chamber yebhureki; apo mafuta ari mukamuri yebrake anosvika kune imwe dzvinyiriro, plunger inodzorwa kuti iende kumusoro, uye cheki chevhavha yakavharwa, kuitira kuti kamuri yakaputika izadzwe nemafuta. Nemhaka yokuti oiri yeinjini haigadzikike, injini painomhanyira panzvimbo yebhureki (kureva kuti, kana piston iri pedyo nepamusoro penzvimbo yakafa), mukuru webhureki ari pacamshaft anosimudza vharafu yerocker roller, uye mabhureki exhaust. vharafu yepamusoro vharafu inosundidzira kuvhura vharafu yekuburitsa pasi pesimba re brake plunger exhaust valve rocker ruoko kuti ibudise chikamu chepamusoro-kudzvanywa gasi. Kana piston yadzika pasi, vharafu yekuburitsa inovhara, uye injini iri mudhiraivha yemotokari yese Inotyairwa kuita basa rakashata (yakaenzana nepamusoro pepiston vacuum), kuitira kuti iwane kudzvanywa kweinjini, kuburitsa. bhureki. Iyo yakakwirira iyo injini inomhanya, iyo yakakura simba rekubhureki.
