Zonse za camshaft ya injini

Camshaft ya injini

Pogwiritsa ntchito injini yoyaka mkati, gawo lililonse limagwira ntchito yofunikira. Pakati pawo - camshaft lapansi. Ganizirani momwe imagwirira ntchito, zolakwitsa zimachitika, ndipo nthawi zina zimafunika kusintha.

Kodi camshaft ndi chiyani

M'ma injini oyatsira mkati omwe ali ndi mitundu inayi ya opaleshoni, camshaft ndi chinthu chofunika kwambiri, popanda mpweya wabwino kapena kusakaniza kwa mpweya wa mpweya sikungalowe muzitsulo. Uwu ndiye tsinde loyikidwa pamutu wa silinda. Ndikofunikira kuti ma valve olowa ndi otulutsa atsegule munthawi yake.

Kamshaft iliyonse imakhala ndi makamera (zowoneka ngati dontho) zomwe zimakankhira wotsatira pisitoni, ndikutsegula dzenje lofananira m'chipinda cha silinda. M'mainjini apamwamba amtundu wachinayi, ma camshaft amagwiritsidwa ntchito nthawi zonse (atha kukhala awiri, anayi kapena amodzi).

Momwe ntchito

Pulley yoyendetsa (kapena asterisk, kutengera mtundu wa nthawi yoyendetsa) imakhazikitsidwa kuchokera kumapeto kwa camshaft. Lamba (kapena unyolo, ngati asterisk yaikidwa) imayikidwa pa iyo, yomwe imagwirizanitsidwa ndi pulley kapena sprocket ya crankshaft. Pakuzungulira kwa crankshaft, torque imaperekedwa pagalimoto ya camshaft kudzera mu lamba kapena unyolo, chifukwa chomwe shaft iyi imatembenuka molumikizana ndi crankshaft.

Gawo lamtanda la camshaft likuwonetsa kuti makamera omwe ali pamenepo ndi owoneka ngati dontho. camshaft ikatembenuka, gawo lotalikirapo la kamera limakankhira pa tappet ya valve, ndikutsegula cholowera kapena chotulukira. Pamene ma valve olowetsa amatsegulidwa, mpweya wabwino kapena kusakaniza kwa mpweya wa mpweya umalowa mu silinda. Pamene ma valve otulutsa atsegulidwa, mpweya wotulutsa mpweya umachotsedwa mu silinda.

Mapangidwe a camshaft amakulolani kuti mutsegule / kutseka ma valve nthawi zonse, ndikuwonetsetsa kuti gasi mukuyenda bwino mu injini. Chifukwa chake, gawo ili limatchedwa camshaft. Pamene torque ya shaft imasunthidwa (mwachitsanzo, lamba kapena unyolo ukatambasulidwa), mavavu samatseguka molingana ndi kukwapula komwe kumachitika mu silinda, zomwe zimapangitsa kuti injini yoyaka moto isagwire ntchito kapena salola kuti iwonongeke. ntchito konse.

Kodi camshaft ili kuti?

Komwe kuli camshaft kumadalira kapangidwe kake ka mota. Mu zosintha zina, ili pansipa, pansi pamiyala yamphamvu. Kusinthidwa kwa ma injini ndikofala, camshaft yomwe ili pamutu wamphamvu (pamwamba pa injini yoyaka mkati). Kachiwiri, kukonza ndi kusintha kwa magawidwe amafuta ndikosavuta kuposa koyambirira.

Kusintha kwa injini zopangidwa ndi V kumakhala ndi lamba wokhazikika, womwe umakhala pakugwa kwa silinda, ndipo nthawi zina gawo limodzi limakhala ndi magetsi ake. Camshaft imakhazikika mnyumbamo yokhala ndi mayendedwe, yomwe imalola kuti izizungulira mosalekeza komanso bwino. M'makina ankhonya (kapena ankhonya), kapangidwe ka injini yoyaka yamkati sikuloleza kukhazikitsa camshaft imodzi. Poterepa, mbali iliyonse ili ndi makina ake ogawa mpweya, koma ntchito yawo imagwirizanitsidwa.

Ntchito ya Camshaft

Camshaft ndichinthu chofunikira munthawi yake (njira yogawa gasi). Imadziwika kuti injini ikukwapulika ndipo imagwirizanitsa kutseguka / kutseka kwa ma valve, omwe amapangira mafuta osakaniza mpweya pazitsulo ndi kuchotsa mpweya wotulutsa mpweya.

Makina omwe amagawira gasi amagwira ntchito molingana ndi mfundo zotsatirazi. Pakadali pano poyambitsa injini, sitata idayamba zikopakutsinde... Camshaft imayendetsedwa ndi unyolo, lamba pamwamba pa crankshaft pulley, kapena magiya (mgalimoto zambiri zakale zaku America). Valavu yodyetsera mu silinda imatsegulidwa ndipo mafuta osakaniza ndi mpweya zimalowa mchipinda choyaka moto. Panthawi imodzimodziyo, chojambulira cha crankshaft chimatumiza kugunda kwazitsulo zoyatsira. Kutulutsa kumapangidwa mmenemo, komwe kumapita kuthetheka pulagi.

Pofika nthawi yomwe kuthetheka kumawonekera, mavavu onse omwe ali mu silinda amakhala atatsekedwa ndipo osakaniza mafuta amafinyidwa. Pakati pa moto, mphamvu imapangidwa ndipo pisitoni imatsikira pansi. Umu ndi momwe crankshaft imasinthira ndikuyendetsa camshaft. Pakadali pano, amatsegula valavu yotulutsa utsi, yomwe imatulutsa mpweya panthawi yoyaka.

Camshaft nthawi zonse imatsegula valavu yoyenera kwakanthawi komanso kutalika kwake. Chifukwa cha mawonekedwe ake, chinthu ichi chimatsimikizira kuzungulira kwa kayendedwe kamene kali mgalimoto.

Zambiri pazigawo zotsegulira ndi kutseka mavavu, komanso makonda ake, zikuwonetsedwa muvidiyoyi:

Magawo pa camshafts, ndi zomwe zimayenera kuchitika? Kodi "camshaft phase" ndi chiyani?

Kutengera kusintha kwa injini, kumatha kukhala kamshafts imodzi kapena zingapo. M'magalimoto ambiri, gawo ili lili pamutu wamphamvu. Zimayendetsedwa ndi kusinthasintha kwa crankshaft. Zinthu ziwirizi zimalumikizidwa pogwiritsa ntchito lamba, unyolo wa nthawi kapena sitima yamagalimoto.

Nthawi zambiri, camshaft imodzi imakhala ndi injini yoyaka mkati yomwe ili ndi mzere wazitsulo. Zambiri mwa injinizi zimakhala ndi mavavu awiri pa silinda (polowera imodzi ndi malo amodzi). Palinso zosintha ndi mavavu atatu pa yamphamvu iliyonse (awiri polowera, mmodzi kubwereketsa). Ma injini okhala ndi ma valve 4 pa silinda nthawi zambiri amakhala ndi migodi iwiri. M'makina oyaka moto omwe ali ndi mawonekedwe a V, ma camshafts awiri amakhazikitsidwanso.

Ma Motors okhala ndi shaft imodzi yokha amakhala ndi kapangidwe kosavuta, komwe kumabweretsa kutsika kwa mtengo wagawo panthawi yopanga. Zosinthazi ndizosavuta kusamalira. Zimayikidwa nthawi zonse pamagalimoto osanja.

Pogwiritsa ntchito makina okwera mtengo kwambiri, opanga ena amaika camshaft yachiwiri kuti ichepetse katundu (poyerekeza ndi kusankha kwa nthawi ndi shaft imodzi) komanso mitundu ina ya ICE kuti isinthe magawo ogawa mpweya. Nthawi zambiri, dongosolo lotere limapezeka mgalimoto zomwe ziyenera kukhala zamasewera.

Camshaft nthawi zonse imatsegula valavu kwakanthawi kanthawi. Pofuna kukonza magwiridwe antchito a mota pamtunda wapamwamba, nthawi imeneyi iyenera kusinthidwa (injini ikufuna mpweya wambiri). Koma ndikukhazikika kwa magwiritsidwe amagetsi, pochulukitsa liwiro la crankshaft, valavu yolowera imatsekedwa mpweya usanalowe mchipinda.

Nthawi yomweyo, ngati mungakhazikitse camshaft yamasewera (makamu amatsegula mavavu olandila kwanthawi yayitali komanso kutalika kwina), pama liwiro a injini zochepa, pamakhala mwayi woti valavu yolowera idzatsegulidwe ngakhale valavu isanatseke. Chifukwa cha ichi, osakaniza ena adzalowa mu dongosolo la utsi. Zotsatira zake ndikutaya mphamvu pamphamvu zochepa komanso kuwonjezeka kwa mpweya.

Njira yosavuta yokwaniritsira izi ndikukhazikitsa camshaft pamakina ena poyerekeza ndi crankshaft. Njirayi imalola kutseka / kutsegulira koyambirira / mochedwa kwa ma valve ndi ma utsi. Pa rpm mpaka 3500, izikhala pamalo amodzi, ndipo malowa atagonjetsedwa, shaft imatembenuka pang'ono.

Wopanga aliyense wopangitsa magalimoto ake kukhala ndi makina oterewa amawonetsa zolemba zake. Mwachitsanzo, Honda imanena VTEC kapena i-VTEC, Hyundai imafotokoza CVVT, Fiat - MultiAir, Mazda - S-VT, BMW - VANOS, Audi - Valvelift, Volkswagen - VVT, ndi zina zambiri.

Mpaka pano, kuti tiwonjezere magwiridwe antchito amagetsi, makina amagetsi amagetsi opumira opanda mpweya akupangidwa. Ngakhale zosinthazi ndizokwera mtengo kwambiri kuzipanga ndi kuzisamalira, motero sizinayikidwe pamakina opanga.

Kuphatikiza pakugawidwa kwa injini, gawo ili limayendetsa zida zowonjezera (kutengera kusintha kwa mota), mapampu amafuta ndi mafuta, komanso shaft yogawira.

Kapangidwe ka Camshaft

Ma Camshafts amapangidwa ndi kulipira, kuponyera kolimba, kuponyera zopanda pake komanso zosintha zaposachedwa kwambiri zawoneka. Cholinga chosinthira ukadaulo wa chilengedwe ndikuwunikira kapangidwe kake kuti zithe kugwira bwino ntchito yamagalimoto.

Camshaft imapangidwa ngati ndodo, pomwe pamakhala zinthu zotsatirazi:

• Sock. Uku ndikutsogolo kwa shaft komwe njirayo imapangidwira. Pulley yanyengo yayikidwa pano. Pankhani yoyendetsa unyolo, asterisk imayikidwa m'malo mwake. Gawo ili limakonzedwa kuyambira kumapeto ndi bolt.
• Khosi losindikiza mafuta. Amalumikiza chidindo cha mafuta kuti mafuta asatuluke mumakinawo.
• Khosi lothandizira. Chiwerengero cha zinthu zotere chimadalira kutalika kwa ndodo. Makina othandizira amakwera pa iwo, omwe amachepetsa mphamvu zotsutsana pakuzungulira kwa ndodo. Zinthu izi zimayikidwa pamakina ofanana pamutu wamphamvu.
• Makamera. Izi zimatuluka ngati mawonekedwe achisanu. Pakazungulira, amakankhira ndodo yolumikizidwa ndi rocker dzanja (kapena valavu yokhayo). Chiwerengero cha makamu chimadalira kuchuluka kwa ma valve. Kukula ndi mawonekedwe awo amakhudza kutalika ndi kutalika kwa kutseguka kwa valavu. Chosalala kwambiri, msanga valavu idzatseka. Mosiyana ndi zimenezi, m'mphepete mwakuya mumasungunuka valavu pang'ono. Wowonda kwambiri shaft shaft, ndiye kuti valavu itsikira pansi, zomwe zimawonjezera kuchuluka kwa mafuta ndikuthandizira kuchotsedwa kwa mpweya wotulutsa utsi. Mtundu wa nthawi ya valavu umadziwika ndi mawonekedwe amakamu (opapatiza - pamawiro ochepa, kutambalala - kuthamanga kwambiri). 
• Njira zamafuta. Phako limapangidwa mkati mwa shaft yomwe mafuta amapatsira makamu (iliyonse ili ndi kabowo kakang'ono). Izi zimalepheretsa kukankhira msanga kwa ndodo ndi kuvala pa ndege za cam.

Ngati camshaft imodzi imagwiritsidwa ntchito popanga injini, ndiye kuti ma cams omwe ali mkati mwake amakhala kuti gawo limodzi limasunthira mavavu olowera, ndipo gawo locheperako limasunthira mavavu otulutsa. Injini zokhala ndi zonenepa zokhala ndi ma polowera awiri ndi mavavu awiri okhala ndi ma camshafts awiri. Poterepa, m'modzi amatsegula mavavu olowera, ndipo winayo amatsegula mpweya wotulutsa utsi.

Mitundu

Kwenikweni, ma camshafts samasiyana kwenikweni wina ndi mnzake. Njira zogawa gasi zimasiyana kwambiri mumainjini osiyanasiyana. Mwachitsanzo, mu machitidwe a ONS, camshaft imayikidwa pamutu wa silinda (pamwamba pa chipika), ndikuyendetsa mwachindunji ma valve (kapena kupyolera mu pushers, hydraulic lifters).

Mu njira zogawa gasi zamtundu wa OHV, camshaft ili pafupi ndi crankshaft pansi pa cylinder block, ndipo ma valve amayendetsedwa kudzera pazitsulo za pushrod. Kutengera ndi nthawi yanthawi yake, camshaft imodzi kapena ziwiri pa banki ya silinda imatha kukhazikitsidwa pamutu wa silinda.

Ma camshaft amasiyana pakati pawo pamtundu wa makamera. Ena amakhala ndi "madontho" otalikirapo, pomwe ena, m'malo mwake, amakhala ndi mawonekedwe ocheperako. Kukonzekera kumeneku kumapereka matalikidwe osiyanasiyana a kayendetsedwe ka valve (ena amakhala ndi nthawi yayitali yotsegula, pamene ena amatsegula motalika). Zinthu zotere za ma camshafts zimapereka mipata yambiri yosinthira injini posintha ma torque ndi kuchuluka kwa ma VTS.

Mwa camshaft ikukonzekera pali:

1. Udzu. Amapereka injini yokhala ndi torque yayikulu pama rpms otsika, omwe ndi abwino pakuyendetsa mzinda.
2. Pansi-pakati. Ichi ndiye tanthauzo lagolide pakati pa ma revs otsika ndi apakatikati. Kamshaft iyi imagwiritsidwa ntchito nthawi zambiri pamakina othamangirako.
3. Hatchi. Mu motors ndi camshafts amenewa, makokedwe pazipita likupezeka pa revs pazipita, amene ali ndi zotsatira zabwino pa liwiro la pazipita galimoto (poyendetsa pa khwalala).

Kuphatikiza pa camshafts yamasewera, palinso zosintha zomwe zimatsegula magulu onse a valve (zonse zolowetsa ndi kutulutsa mpweya pa nthawi yoyenera). Kwa ichi, magulu awiri a cam amagwiritsidwa ntchito pa camshaft. Machitidwe anthawi ya DOHC ali ndi ma camshaft omwe amalowetsa komanso kutulutsa mpweya.

Kodi chojambulira cha camshaft chimayambitsa chiyani?

Mu injini za carburetor, wofalitsa amalumikizidwa ndi camshaft, yomwe imatsimikizira gawo lomwe limachitika mu silinda yoyamba - kudya kapena kutulutsa.

Palibe wofalitsa mu injini zoyaka zamkati zamkati, chifukwa chake, camshaft position sensor ili ndi udindo wodziwitsa magawo a silinda yoyamba. Ntchito yake siyofanana ndi ya crankshaft sensor. Pakusintha kwathunthu kwathunthu kwa shaft shaft, crankshaft itembenuza olamulira kawiri.

DPKV imakonza TDC ya pisitoni ya silinda yoyamba ndikupatsa chidwi kuti ipange kutulutsa kwa pulagi. DPRV imatumiza chizindikiritso ku ECU, ndi nthawi iti yomwe muyenera kuyatsa mafuta ndikutulutsa silinda yoyamba. Zozungulira zazitsulo zotsala zimachitika mosiyanasiyana kutengera kapangidwe ka injini.

Chojambulira cha camshaft chimakhala ndi maginito ndi semiconductor. Pali chikhazikitso (dzino laling'ono lazitsulo) pamtengowu nthawi yayitali pakapangidwe kazipangizo. Pakati pa kasinthasintha, chinthu ichi chimadutsa pa chojambulira, chifukwa maginito omwe ali mmenemo amatsekedwa ndikupanga komwe kumapita ku ECU.

Makina oyang'anira zamagetsi amalemba momwe zimakhalira. Amatsogozedwa ndi iwo mukamadyetsa ndikuyatsira mafuta osakaniza mu silinda yoyamba. Pankhani yokhazikitsa migodi iwiri (imodzi yopangira sitiroko, ndi inayo ya utsi), aliyense wa iwo adzaikapo sensa.

Kodi chimachitika ndi chiyani ngati sensor ikulephera? Kanemayu waperekedwa patsamba ili:

PHASE SENSOR CHIFUKWA CHIYANI ZOFUNIKIRA ZOFUNIKA ZA KULEPHERA KWAKE DPRV

Ngati injini ili ndi pulogalamu yamagetsi yosinthira nthawi, ndiye kuti ECU imasankha kuchokera pafupipafupi pamphindi iti yomwe ndiyofunika kuchedwa kutsegula / kutseka ma valve. Pankhaniyi, injini adzakhala okonzeka ndi chipangizo zina - gawo shifter (kapena hayidiroliki zowalamulira), amene akutembenukira camshaft kusintha nthawi yoyamba. Ngati kachipangizo ka Hall (kapena camshaft) kali ndi vuto, nthawi yamagetsi siyisintha.

Mfundo yogwiritsira ntchito DPRV mu injini za dizilo imasiyana ndi momwe amagwiritsira ntchito mafuta ofanana. Poterepa, imakonza malo omwe ma pistoni onse ali pamwamba pakatikati panthawi yamafuta osakanikirana. Izi zimapangitsa kuti athe kudziwa molondola malo a camshaft poyerekeza ndi crankshaft, yomwe imakhazikitsa magwiridwe antchito a injini ya dizilo ndikupangitsa kuti izikhala zosavuta kuyamba.

Zowonjezera zowonjezera zawonjezeredwa pakupanga kwa masensa otere, malo omwe pa master disk amafanana ndi kupendekera kwa valavu yapadera mu silinda yapadera. Zipangizo zamtunduwu zimatha kusiyanasiyana kutengera mtundu wazomwe opanga osiyanasiyana.

Mitundu yamakina osinthira camshaft mu injini

Kutengera mtundu wa injini, imatha kukhala ndi migodi imodzi, iwiri kapena inayi yogawa gasi. Kuti zikhale zosavuta kudziwa mtundu wa nthawi, zilembo zotsatirazi zimagwiritsidwa ntchito pachikuto chamutu:
