I-Schwing Drive Slewing Lever

I-attake rocker assembly ingenisa umxube otshayo (okanye umoya omtsha) kwi-cylinder; emva koko ucinezele umxube otshayo (okanye umoya omtsha) kwi-cylinder, kwaye uvutha umxube ovuthayo xa ukunyanzeliswa kusondele kwinqanaba lokugqibela (okanye ujobe idizili kwi-cylinder ukwenza umxube ovuthayo kwaye uwutshise); umxube ovuthayo uyavutha kwaye utshise, kwaye ukwandiswa kutyhala ipiston ezantsi ukufezekisa umsebenzi wangaphandle; ekugqibeleni, igesi yokukhupha emva kokutshiswa iyakhutshwa. Oko kukuthi, ukungena komoya, ukunyanzeliswa, umsebenzi, ukukhupha iinkqubo ezine. Ikwangumthombo wamandla welori

Iindlela zokunyanzeliswa kwe-injini ziquka i-exhaust braking, i-air release braking kunye ne-compress release braking. I-injini ithatha imo ye-compress yokukhululwa kwe-braking, kwaye imo yokusebenza yayo ilandelayo:

Xa kungekho ziqhoboshi, i-valve ye-solenoid ye-brake iyacinywa kwaye ezinye iindawo azikwazi ukuzaliswa ngeoli. Xa i-injini ibaleka kwindawo yomphathi we-brake (oko kukuthi, xa ipiston isondele kwiziko eliphezulu elifileyo), ibloko ephezulu yevalve yokukhupha ifuna kuphela ukoyisa amandla entwasahlobo kwiplunger. Ngeli xesha, umphathi we-brake kwi-camshaft ayisebenzi kwaye akayi kutyhala ivalve yokukhupha. Injini isebenza ngokuqhelekileyo.

Ubume be-exhaust rocker arm assembly: xa kufuneka isiqhoboshi, vula iswitshi ye-injini yebrake, cofa i-pedal ye-brake, kwaye i-ECU ilawula inkqubo yamafutha ukuba iyeke ukubonelela nge-oyile. Ngeli xesha, ivalve yebrake solenoid iyasebenza kwaye ivuliwe, kwaye i-oyile evela kwipaseji yeoli encedisayo kwi-rocker arm shaft igquma i-oyile yokungena kwi-rocker arm bushing kunye ne-oyile encedisayo yepaseji yengalo yerocker, kwaye ingena Ukuqhekeza igumbi le-plunger yesiqhoboshi; xa ioli ekwigumbi lokuqhawula ifikelela kuxinzelelo oluthile, i-plunger ilawulwa ukuba inyuke, kwaye i-valve yokukhangela ivaliwe, ukwenzela ukuba igumbi lokuqhawula lizaliswe ngeoli. Ngenxa yokuba i-oyile ye-injini ayicinezeleki, xa i-injini ibaleka isiya kwindawo yomphathi we-brake (oko kukuthi, xa ipiston ikufuphi nendawo ephezulu efileyo), umphathi we-brake kwi-camshaft uphakamisa i-valve ephumayo, kunye ne-exhaust ye-brake. Ivalve ephezulu ityhala ivule ivalve yokukhupha phantsi kwamandla ebrake plunger exhaust valve rocker arm ukukhupha inxalenye yerhasi yoxinzelelo oluphezulu. Xa ipiston yehla, ivalve yokukhupha iyavala, kwaye injini ikwinkqubo yokuqhuba yesithuthi sonke Iqhutywa ukwenza umsebenzi ongalunganga (olingana nomphezulu wevacuum yepiston), ukuze kufezekiswe ukucinezelwa kwe-injini, ukukhulula. isiqhoboshi. Okukhona siphezulu isantya senjini, kokukhona sisiba makhulu amandla okuqhobosha.
