Crankshaft dabaran dabaran siginar.
Babban rawar da dabaran siginar crankshaft shine don ƙayyade daidai matsayi da Angle na crankshaft, kazalika da saurin injin. Yawancin lokaci yana aiki tare da firikwensin matsayi na camshaft don tabbatar da ingantaccen aikin injin da haɓaka aiki. Don zama takamaiman:
Ƙayyade matsayi na crankshaft: Ƙaƙwalwar sigina na crankshaft, ta hanyar ƙayyadaddun ƙira da matsayi, yana ba da damar firikwensin don gane daidai matsayi na yanzu da kuma kusurwa na crankshaft, wanda ke da mahimmanci don sarrafa lokacin ƙonewa da allurar man fetur.
Yin aiki tare da firikwensin matsayi na camshaft: Dabarar siginar crankshaft tana aiki tare da firikwensin matsayi na camshaft don tantance ainihin lokacin kunnawa. Wannan haɗin gwiwar yana tabbatar da cewa za'a iya harba injin a lokacin da ya dace don aiki mai santsi da inganci.
Ana amfani da dabaran siginar siginar crankshaft gabaɗaya 60-2 dabaran siginar haƙori, akwai ɓangaren haƙori da ya ɓace, ta firikwensin gwargwadon siffar haƙori da babban siginar ƙaramin matakin siginar haƙorin da ya ɓace don yin hukunci akan crankshaft lokaci 1. Wannan zane yana ba da damar firikwensin don yin hukunci daidai matsayi da lokaci na crankshaft ta hanyar haƙorin haƙori da manyan sigina da ƙananan sigina na haƙorin da ya ɓace, , don haka cimma daidaitaccen sarrafa yanayin aikin injin. Ƙirar ƙira ta musamman na ƙirar siginar crankshaft, haɗe tare da sarrafa siginar crankshaft ta hanyar ECU (nau'in kula da lantarki), yana ɗaya daga cikin mahimman fasahar don gane ingantaccen aiki da kwanciyar hankali na injin. "
Kula da saurin injin: Motar siginar crankshaft shima yana lura da saurin injin kuma yana watsa bayanai zuwa ECU (nau'in sarrafa lantarki) don daidaitaccen sarrafa lokacin kunna wuta da lokacin allura, wanda ke da mahimmanci don haɓaka ingancin mai da rage hayaƙi.
A takaice, dabaran siginar crankshaft wani abu ne mai mahimmanci a cikin injunan zamani, yana taimakawa tsarin sarrafa injin inganta aiki da tabbatar da aiki mai aminci ta hanyar samar da ingantaccen matsayi da bayanai na sauri.
Menene bayyanuwar gazawar siginar crankshaft?
Idan faifan siginar crankshaft ya gaza, zai yi tasiri iri-iri kan aikin motar da aka saba, musamman kamar haka:
Na farko, alamar kuskure tana haskakawa, wanda shine ra'ayin kai tsaye na tsarin binciken abin hawa bayan gano matsalar. Na biyu, a lokacin da za a fara mota, za ka iya gane cewa farawa ya fi tsayi fiye da yadda aka saba, saboda injin yana ƙoƙarin farawa ta hanyar camshaft matsayi na firikwensin, amma saboda kuskuren faifan siginar, tsarin farawa ya cika. Yayin tuki, aikin tafiye-tafiye iri ɗaya na abin hawa zai iya shafar kuma ba zai iya aiki akai-akai. Bugu da kari, injin na iya bayyana girgizar da ba ta dace ba, har ma tana fitar da farin hayaki.
Babban aikin firikwensin matsayi na crankshaft shine kula da saurin injin, kuma bisa ga wannan bayanin don ƙayyade adadin allurar mai da ƙonewa gaba Angle. Wannan yana tabbatar da cewa an kunna injin kuma an kunna shi a mafi kyawun lokaci, don haka rage lalacewar motar. Duk da haka, lokacin da akwai matsala tare da siginar siginar crankshaft, wannan jerin ayyukan kulawa da daidaitawa za a iya shafa, wanda ya haifar da aikin injiniya maras kyau.
Ana shigar da firikwensin matsayi na crankshaft a cikin mai rarrabawa, wanda shine muhimmin sashi don gano matsayin TDC na piston, don haka wani lokaci ana kiran shi firikwensin TDC. Da zarar wannan firikwensin ya gaza, ya kamata a duba shi kuma a gyara shi nan da nan don hana gazawar fadadawa da yin lahani ga abin hawa.
