Niki valve rocker ukuboko na tappet
Imodoka ya valve rocker arm na tappet nibice byingenzi byuburyo bwa moteri yimodoka, kandi buri kimwe gifite imikorere ningaruka zihariye.
Valve rocker ukuboko
valve rocker arm ni igice cyingenzi cyimikorere ya moteri ya moteri, uruhare rwayo nyamukuru nugukorana na camshaft kugirango hafungurwe mugihe cyo gufunga no gufunga mugihe, kugirango urangize inzira yo gufata no gusohora. Ukuboko kwa rocker ni ukuboko kwamaboko abiri hamwe nu mwobo wo hagati wo hagati nka fulcrum. Ukuboko kugufi kwarimo ibikoresho byo guhinduranya valve kuruhande rumwe, kandi ukuboko birebire guhabwa arc ikora mumaso kugirango isunike valve .
Tapeti
Igikorwa nyamukuru cya tappet ya valve ni ukwimura icyerekezo nimbaraga za camshaft kumasunzu cyangwa gusunika, hanyuma ugasunika inkoni yo gusunika cyangwa valve kugirango utsinde imbaraga zamasoko ya valve. Tappet ikeneye kwihanganira imbaraga zuruhande zakozwe na CAM mugihe ikora hanyuma ikohereza mumubiri cyangwa mumutwe wa silinderi. Tappets irashobora kugabanywamo imashini zikoreshwa na hydraulic, buri kimwe gifite imiterere n'imikorere yihariye:
Tappet yumukanishi : mubisanzwe bikozwe mubyuma bivanze cyangwa ibyuma bisize ibyuma birwanya kwambara neza. Imiterere iroroshye ariko gukuraho valve bigomba guhinduka buri gihe.
Tappet hydraulic tappet : Mu buryo bwikora ikuraho gukuraho valve itabanje guhinduka kandi igabanya urusaku rwohereza. Tappet ya hydraulic igizwe numubiri wa tappet, plunger nisoko yindishyi, nibindi, bihita bihindurwa nigitutu cyamavuta nigikorwa cyamasoko .
Porogaramu yihariye ikoreshwa nibyiza nibibi
Tappet yumukanishi : imiterere yoroshye, ariko ikenera kubungabungwa buri gihe no guhindura imikorere ya valve. Irakoreshwa mubintu bidasaba kubungabungwa cyane.
Tappet hydraulic tappet : imiterere igoye ariko irashobora guhita ihindurwa, kugabanya imirimo yo kubungabunga, ibereye kwizerwa cyane hamwe n urusaku rwibisabwa. Tappet ya hydraulic ihita ihindurwa binyuze mubikorwa byumuvuduko wamavuta nimpeshyi, bishobora gukuraho ububobere bwa valve no kugabanya urusaku rwohereza .
Uruhare rwa valve rocker ukuboko na tappet ahanini bikubiyemo ibintu bikurikira:
Uruhare rwa tappet
Igikorwa nyamukuru cya tappet nukwimura imbaraga za kamashaft kumasunika cyangwa inkoni ya valve, hanyuma ugasunika inkoni cyangwa gusunika kugirango utsinde imbaraga zamasoko ya valve hanyuma ukimuka. Muri icyo gihe, amakariso nayo afite imbaraga zuruhande zikoreshwa no kuzunguruka. Tappet irashobora kugabanywamo ubwoko bubiri: tappet isanzwe na tappet ya hydraulic:
Tappet isanzwe : harimo tappet ya fungus, tappet ya barrel na tappet ya roller. Tappets zisanzwe nuburyo bukomeye kandi ntibishobora guhita bikuraho gukuraho valve, bityo rero birakenewe ko uhindura valve buri gihe.
Tappet hydraulic tappet : irashobora gukuraho ububi bwa moteri ya moteri, nta mpamvu yo guhindura imikorere ya valve, kandi irashobora kugabanya urusaku rwimikorere ya moteri ya valve. Tappet ya hydraulic ihita ihindura neza ya valve ikoresheje umuvuduko wamavuta nigikorwa cyamasoko yindishyi kugirango habeho umubano wa hafi hagati ya valve na CAM .
Uruhare rwamaboko ya rocker
Igikorwa nyamukuru cyamaboko ya rocker nukunyuza imbaraga kuva gusunika inkoni cyangwa CAM kuri valve nyuma yo guhindura icyerekezo kugirango ikingure. Iteraniro ryamaboko ya rocker rigizwe nintoki za rocker, urutoki rwamaboko ya rocker, intebe yunganira, umugozi wo guhinduranya valve nibindi bice. Ibi bice bikorana kugirango hafungurwe neza no gufunga valve, bityo bigenzure uburyo bwo gufata no gusohora no gukora imikorere isanzwe ya moteri .
Ihame ryihariye ryakazi
Iyo moteri ikora, crankshaft itwara kamera kugirango izunguruke binyuze muburyo bwo kohereza, hanyuma CAM kuri camshaft isunika inkoni yo gusunika cyangwa valve binyuze muri tasheti. Iyo igice cyazamuye CAM gisunikishije tappet, tappet ihererekanya imbaraga kumasoko cyangwa gusunika, gufungura valve. Hamwe no kuzunguruka kwa CAM, valve ifunga buhoro buhoro munsi yimikorere yisoko. Ukuboko kwa rocker kohereza imbaraga zinkoni yo gusunika cyangwa CAM kuri valve, ikemeza ko valve ifungura kandi igafunga neza .
