Kodi chosinthira magalimoto ndi chiyani?
Chosinthira magalimoto ndi chipangizo chomwe chimagwiritsidwa ntchito kusintha malo pakati pa camshaft yolowera ndi crankshaft ya injini ya galimoto. Ntchito yake yayikulu ndikusintha gawo la camshaft kudzera mu injini, potero kukonza magwiridwe antchito ndi kusunga mafuta a injini.
Mfundo yogwirira ntchito
Oyang'anira magawo a magalimoto nthawi zambiri amagwiritsa ntchito owongolera magawo amagetsi, ndipo kapangidwe kawo kamakhala ndi njira yotumizira magiya atatu. Limodzi mwa ma shaft limalumikizidwa ku camshaft, shaft ina imayendetsedwa ndi mota, ndipo shaft yachitatu imalumikizidwa ku sprocket kudzera mu stator. Kapangidwe ka makina kakang'ono aka kamalola camshaft, mota yowongolera magawo ndi sprocket kugwira ntchito mogwirizana. Pakufunika kukonza Ngodya ya nthawi, mota imapangitsa liwiro lozungulira la magulu atatuwa kukhala lofanana. Pamene gawo likufunika kusinthidwa, liwiro la mota lidzakhala lachangu kapena locheperako kuposa liwiro la stator malinga ndi momwe ntchito ikuyendera, pomaliza pake limalamulira nthawi yotsegulira/kutseka valavu .
Mitundu ndi zochitika zogwiritsira ntchito
Pali mitundu iwiri makamaka ya ma automotive phase regulators: variable valve timing system (VVT) ndi variable valve lift system (VVL). VVT imasintha mphamvu yotulutsa mphamvu komanso kusunga mafuta mwa kusintha nthawi yotsegulira ma valve olowa ndi otulutsa utsi, pomwe VVL imakonza mphamvu yotulutsa mphamvu komanso kugwiritsa ntchito bwino mafuta mwa kusintha ma valve lift . Machitidwewa amagwiritsidwa ntchito kwambiri m'mainjini amakono a magalimoto, makamaka m'magalimoto omwe ali ndi magwiridwe antchito apamwamba komanso ofunikira kwambiri.
Kusamalira ndi kuzindikira zolakwika
Pofuna kusamalira chowongolera magawo a galimoto, ndikofunikira kwambiri kuyang'ana nthawi zonse momwe injini ikuyendera komanso kulimba kwa maulumikizidwe a makina. Ngati zapezeka kuti injiniyo sikuyenda bwino kapena kusintha magawo sikuli kolondola, kukonza kapena kusintha zinthu zina zofunikira kuyenera kuchitika panthawi yake. Kuphatikiza apo, kuyeretsa nthawi zonse ndi kukonza kapangidwe ka makinawo kuti zitsimikizire kuti ikugwira ntchito bwino ndi njira yothandiza yowonjezera moyo wa wowongolera magawo. Ponena za KUDZIWA ZOSIYANA, kulondola kwa MOTO WA CURRENT, VOLTAGE ndi malamulo a magawo kumatha kuzindikirika kudzera mu zida zaukadaulo zodziwira matenda, kupeza ndi kuthetsa mavuto pakapita nthawi .
Ntchito yayikulu ya modulator ya gawo la galimoto ndikugwiritsa ntchito chizindikiro chosinthidwa kuti chisinthe mwachindunji magawo a loop ya resonant, kotero kuti chizindikiro chonyamulira chikadutsa mu loop ya resonant, kusintha kwa gawo kumapangidwa kuti apange mafunde a gawo la modulation .
Makamaka, modulator ya gawo lamagalimoto imakwaniritsa kusintha ndi kuchotsera chizindikiro mwa kusintha magawo a dera lozungulira kuti akhudze kusintha kwa gawo la chizindikiro.
Mfundo yogwirira ntchito
Mfundo yogwira ntchito ya automotive phase regulator imaphatikizapo kusintha ma signali ndi ma resonant circuits. Signali yosinthidwa imagwiritsidwa ntchito kusintha magawo a resonant circuit, zomwe zimapangitsa kuti carrier signal isinthe gawo ikadutsa mu resonant circuit ndikupanga phase-modulated wave. Njirayi imaphatikizapo kupanga ma electronic circuits ndi njira zopangira ma signali kuti zitsimikizire kuti phase modulator ikhoza kuwongolera bwino kusintha kwa phase ya signali.
Zochitika zogwiritsira ntchito
Ma modulators a gawo la magalimoto amagwiritsidwa ntchito kwambiri m'makina amagetsi a magalimoto, makamaka m'mapulogalamu omwe amafunikira kuwongolera molondola gawo la chizindikiro. Mwachitsanzo, m'makina olumikizirana, modulator ya gawo ingagwiritsidwe ntchito kusintha ndi kuchepetsa zizindikiro kuti zitsimikizire kutumiza kokhazikika kwa zizindikiro. Mu mayunitsi owongolera zamagetsi a magalimoto, ma modulators a gawo angagwiritsidwe ntchito kuwongolera molondola zizindikiro za masensa ndi ma actuator osiyanasiyana, kukulitsa kukhazikika ndi kudalirika kwa dongosololi.
Kulephera kwa inverter yamagalimoto a Youdaoplaceholder0 kumawonekera makamaka ngati zochitika zotsatirazi:
Youdaoplaceholder0 Voltage anomaly : Transistor ya field-effect kapena transistor ya Darlington mkati mwa inverter yawonongeka, zomwe zimapangitsa kuti mphamvu ya excitation isakhale yolamulira, voltage yotulutsa ya jenereta ikwere kapena kutsika mosazolowereka, ndipo batire idzakhala ndi mphamvu yochulukirapo kapena yocheperako .
Youdaoplaceholder0 Kuchepetsa mphamvu yochaja : Jenereta yawonongeka, mphamvu yotulutsa yatsika, ndipo singathe kuchaja batri bwino, zomwe zimapangitsa kuti mphamvu ya batri isakwane .
Youdaoplaceholder0 Chigawo chotseguka : Transistor yogwira ntchito kapena transistor ya Darlington yawonongeka ndi chiwongolero chotseguka, ndipo chingwe chozungulira cha jenereta chimakhazikika pansi, zomwe zimapangitsa kuti chiwongolerocho chikhale chosazolowereka .
Youdaoplaceholder0 Kuchepa kwa magwiridwe antchito a injini : Kuwonjezeka kapena kuchepa kwa mphamvu zopangira magetsi, zomwe zimapangitsa kuti batire itsike, kuvutika kuyambitsa injini, kugwedezeka, kuthamanga pang'ono kapena kuyima.
Youdaoplaceholder0 Zifukwa zolephera zingakhale:
Kuwonongeka kwa chowongolera magetsi: Kuwonongeka kwa transistor yamkati mwa FET kapena Darlington komwe kumapangitsa kuti mphamvu yamagetsi isayende bwino.
Kuwonongeka kwa transistor yotseguka kapena transistor ya Darlington: kumayambitsa kusokonezeka kwa jenereta ndi kupotoza kwa waya pansi.
Kupanga mphamvu zosazolowereka: Kupanga mphamvu mopitirira muyeso kapena kosakwanira kumakhudza mphamvu ya batri ndi magwiridwe antchito a injini.
Youdaoplaceholder0 Njira zowunikira ndi kukonza :
Youdaoplaceholder0 Chongani mphamvu yamagetsi yotulutsa jenereta : Gwiritsani ntchito multimeter kuti muyese mphamvu yamagetsi yotulutsa jenereta kuti mudziwe ngati ndi yachibadwa.
Youdaoplaceholder0 Yang'anani magetsi a batri : Gwiritsani ntchito multimeter kuti muyese magetsi a batri kuti mudziwe ngati ali mkati mwa malire oyenera.
Youdaoplaceholder0 Yang'anani momwe ntchito ya wowongolera ikuyendera: Poona momwe ntchito ya wowongolera ikuyendera, dziwani ngati pali vuto lililonse.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
