Kodi lamba wa nthawi ndi mtundu wanji womwe muyenera kusankha?

Kukonza sikokwanira popanda kuyang'ana ndipo, ngati kuli kotheka, m'malo mwa lamba wanyengo. Makina opanga magalimoto ambiri amakakamiza omwe amakhala ndi galimoto kuti asinthe chinthucho pomwe galimoto yatsopanoyo idutsa ma mileage omwe afotokozedwayo.

M'nkhaniyi, tikambirana momwe chidule cha nthawi chimayimira, chifukwa chake chinthuchi chimafunikira mu injini yoyaka mkati, chiopsezo chotuluka chake, pamene chikuyenera kusinthidwa ndi chatsopano, momwe mungasankhire lamba woyenera .

Kodi lamba wamagalimoto ndi chiyani?

M'galimoto, nthawi yamba ndi chinthu chozungulira ngati mphete yotseka. Gawoli limapangidwa ndi mphira waluso. Gawo lamkati limalimbikitsidwa ndi ulusi wopangira womwe umalepheretsa kutambalikako ndikuwonjezera kuuma kwa chinthucho. Kunja, lamba ndi wosalala, ndipo mkati mwake muli mano.

Izi zimatchedwanso lamba woyendetsa. Injini iliyonse imakhala ndi kukula kwake ndipo motero imakhala ndi gawo laling'ono la lamba. Palinso magalimoto omwe amagwiritsa ntchito tcheni m'malo mwa lamba wampira. Ndemanga yapadera imanena za mitundu yamagalimoto yomwe ili ndi mtundu wamtunduwu.

M'zaka za m'ma 1950, magalimoto ambiri ankagwiritsa ntchito tcheni, koma nthawi yoyendetsayi inali yaphokoso kwambiri komanso yolemera. Pogwira ntchito yake, damper ndi nsapato yovuta imafunika. Zinthu izi zidapangitsa kuti chipangizocho chikhale chovuta komanso cholemera, chomwe chimakhudza magwiridwe antchito agalimoto.

Pamene opanga makina amayesa kusintha lamba woyendetsa ndi lamba woyendetsa, poyambira oyendetsa sanatenge ndi chidwi chachikulu. Koma popita nthawi, lamba wanyamula watsimikizira kuti ndiwothandiza: injini yakhala yopepuka, yosavuta komanso yotsika mtengo kuyisamalira.

Kuti mumvetse zomwe lamba uja akuyenera, muyenera kudziwa kanthawi kanthawi.

Nthawi ndi njira yogawa gasi, yomwe imayikidwa pamutu wamphamvu kwambiri m'mayunitsi amakono amakono. Zapangidwa kuti zigawidwe moyenera magawo (kudya / utsi) mu silinda iliyonse ya injini. Zambiri pazomwe nthawi ya valavu ili, yafotokozedwa kubwereza kwina... Makinawa amatsegula ndikutseka mavavu olowera ndi kutulutsa ntchito pogwiritsa ntchito camshaft (pakapangidwe ndi magwiridwe antchito a gawo ili, werengani apa).

Pali zosintha zitatu za njirazi. Amasiyana wina ndi mzake pamalo a camshaft ndi ma valve. Izi ndi mitundu ya ma drive:

1. Ma valve ali pamutu wamphamvu ndipo camshaft ili pansi pa injini. Pofuna kuyambitsa nthawi ya valavu, camshaft imayendetsa ma valve m'miyendo yama rocker ndikukankhira ndodo. Kusintha kotereku kwakanthawi sikuloleza kukula kwa ma crankshaft apamwamba, omwe amachititsa kuti mphamvu yoyaka mkati ikuvutike.
2. Mavavu amakhala pansi pamiyala yamtengo wapatali pomwe ma mbale akuyang'ana mmwamba. Poterepa, camshaft ipezanso kumunsi kwa injini, ndipo ma cams akuyendetsa kale ma valve okha. Magalimoto awa ali ndi mafuta ovuta kwambiri, omwe amathandizira kukonza ndi kukonza kwa unit.
3. Mtundu wofala kwambiri wamaimidwe okhala ndi camshaft ndi ma valve (pamutu wamphamvu). Camshaft imodzi imatha kugwiritsira ntchito ma valve onse kapena ma valve oyamwa kapena otulutsa. Pali zosintha momwe ma cams amasindikizira pamiyala yama rocker, komanso molunjika pa ma valve.

Mosasamala mtundu wanji wamagetsi omwe amagwiritsidwa ntchito mu injini, momwe amagwirira ntchito ndi yemweyo - kutsegula valavu yofananira munthawi yomwe pisitoni imagwira utsi kapena kuponda (zomwe injini zikumenya, zimatiuza apa). Nthawi yotsegulira valavu imadaliranso momwe makina akugwirira ntchito. Gawo shifter limagwiritsidwa ntchito mu injini zamakono.

Makina ogawira gasi akapanda kukhazikitsidwa bwino, injiniyo imasokonekera ngakhale pang'ono. Pazovuta kwambiri, sizigwira ntchito.

Ili kuti lamba wanyengo m'galimoto?

Nthawi yamba ili kumbali inayo ya flywheel (ndi chiyani ndikusintha komwe kulipo, werengani apa). Zimakwanira pamwamba pa crankshaft ndi pulley yama camshaft. Zitha kupangidwa ngati magiya akuluakulu kapena mapulagi wamba. Poyambirira, ndikumangirira kolimba kofooka, sikungaterere, chifukwa chomwe nthawi yamagetsi idzatsalira.

Zingwe zoyambirira zidalimbikitsidwa ndi makhothi achitsulo, koma zosintha zotanuka kwambiri ndizomwe zimakhala ndi ulusi wopangira. Mpira umatsimikizira phokoso lochepa la gawolo. Mosasamala kapangidwe ka pulleys yamagalimoto oyendetsa galimoto, lamba nthawi zonse amakhala ndi mano, omwe amatsimikizira kulumikizana kwabwino kwa mawonekedwe azigawo.

Kuphatikiza pakukhazikitsidwa pa camshafts ndi crankshafts, lamba amalumikizanso ku unit ndi zolumikizira zina, monga pampu. Njira zina zonse zimalumikizidwa ndi mota pogwiritsa ntchito malamba awo.

Dongosolo, zingakhale zosavuta kulumikiza njira zonse ndi lamba umodzi, koma izi zidzachepetsa kwambiri moyo wautumiki wa chinthuchi. Mosasamala mtundu wamagalimoto, opanga makina azipanga kukhala kosavuta kotheka kulumikiza lambayo kuti zikhale zosavuta kuziyang'ana ndikusintha.

Mtundu uliwonse wamagalimoto uli ndi lamba wake wa nthawi, chifukwa kapangidwe ka ma mota ndi osiyana. Pazochitika zonsezi, kukula kwake kwa mphete kudzakhala kosiyana. Kuonetsetsa mphamvu pazipita kukonza chinthu ichi pa pulleys, izo tensioned ntchito wodzigudubuza wapadera (nthawi zambiri amagulitsidwa ndi lamba).

Kodi lamba wa nthawi yake ndi chiyani?

Kutengera mtundu wa injini, chisakanizo chokonzekera kale cha mpweya ndi mafuta, kapena mpweya wokha (ngati injini ili ndi jekeseni wachindunji), umalowa mu silinda kudzera ma valve. Kuti valavu iliyonse itsegule ndikutseka munthawi yake, makina opangira gasi amayenera kugwirizanitsidwa ndi ntchito crankshaft.

Ntchitoyi imagwiridwa ndi lamba woyendetsa. Ntchito yowonjezerapo ya chinthuchi ndikuwonetsetsa kuti kuziziritsa kwanthawi zonse kuzizizira (ngati kapangidwe kake ka injini kumathandizira kuyanjana kwa njirazi). Pamene injini ikuyenda, lamba amasinthasintha malo oyendetsa pampu. Komanso, pama mota ambiri, makina oyaka amkati oyenda amaphatikizaponso kalunzanitsidwe ka mpope wamafuta.

Cholinga ndi momwe ntchito imagwirira ntchito

Chifukwa chake, monga mukuwonera, kulumikizana kwa magwiridwe antchito amagetsi ndi crankshaft zimatengera lamba wa nthawi. Ali panjira, imatsimikizira kugwira ntchito kwa mpope wamadzi ndi mpope wamafuta. Kodi element imagwira ntchito bwanji?

Chifukwa chogwira nawo ntchito ma pulleys onse oyenerera molingana ndi kapangidwe ka injini yoyaka mkati, galimoto ikayamba, oyambitsa amatembenuza chowulutsira, ndipo izi zimapangitsa kuti crankshaft izizungulira. Makina opendekera amayamba kusuntha ma pistoni mkati mwa zonenepa.

Nthawi yomweyo, mphamvuyi imafalikira ku lamba wa nthawi ndikudutsa mu camshaft pulley. Pakadali pano, ma valve amayamba kutseguka ndikutseka molingana ndi sitiroko yomwe imachitika m'ma cylinders.

Kutulutsa kwa mpope wamadzi kumayamba kuzungulira mozungulira, ndipo kuyendetsa mpope wamafuta kumayambitsidwa. Crankshaft position sensor (ndi chiyani komanso imagwira ntchito bwanji, imatero apa) amakonza malo a pisitoni mu silinda yoyamba ndikuwonjezera kuphulika kwa magetsi. Gawo latsopano la mafuta osakanikirana ndi mpweya amalowa m'miziramo kudzera m'magetsi. Chikhumbo chimagwiritsidwa ntchito pa kandulo yofananira ndipo BTC imayatsa. Chipangizocho chimathamanga popanda kuthandizidwa.

Ngati lambayo atazembera, kulumikizana kwa gulu lamphamvu-pisitoni ndi nthawi ya valavu kudzasokonezedwa. Poterepa, ma valve sadzatseguka molingana ndi zikwapu zamagalimoto. Kutengera mtundu wamagalimoto komanso kuchuluka kwa zosokoneza izi, makina oyaka amkati amatha kukhala osakhazikika kapena okhazikika. Pachifukwa ichi, ndikofunikira kuti nthawi ndi nthawi muziwona kupindika kwa mphete yoyendetsa.

Kufotokozera kwakusintha kwa nthawi ya lamba

Monga tanenera kale, galimoto iliyonse ili ndi lamba wake. Kuti woyendetsa galimoto asasokoneze gawolo, kunja kumakhala chinthu chomwe chikugulitsa. Nayi mbiri ya aliyense wa iwo. Mu manambala, wopanga amabisa kuchuluka kwa mano, mamvekedwe ake ndi mbiri yake, komanso m'lifupi mwake. Malinga ndikulemba kwapadziko lonse lapansi (ISO), mayina am'magulu amatha kutanthauzidwa motere:

92147x19 - 92 (mbiri ya dzino); 147 (chiwerengero cha mano); 19 (m'lifupi).

Pa lamba palokha pamatha kulembedwa motere: 163 RU 25.4 24315 42200 CR. Chiwerengero choyamba chikufanana ndi kuchuluka kwa mano, chachiwiri kukula kwa mankhwala. Mayina ena onsewa akuwulula tsatanetsatane wa mawonekedwe a mano ndi magawo ena.

Chidwi chachikulu chiyenera kulipidwa ku tanthauzo lenileni. Lamba amatha kudziwika ndi CR, HNBR kapena EPDM. Iliyonse ya iwo imawonetsa zinthu zomwe zinthuzo zimapangidwa:

• Kr - chloroprene. Ndi kupanga labala. Zomwe zimalekerera nyengo kusintha bwino, sizimawotcha. Ngati galimoto nthawi zambiri imayenda m'misewu yafumbi, muyenera kumvetsera izi, chifukwa zawonjezera kukana kutuluka. Kugonjetsedwa ndi mafuta aukali komanso mafuta a injini. Kutentha kwa magwiridwe antchito kumachokera ku -40 mpaka +160 madigiri.
• RPDM ndi mphira woyambira wa ethylene-propylene-diene. Ilinso mtundu wa mphira wopangira. Zinthuzo zimatha kusungidwa kwa nthawi yayitali. Ndi kugonjetsedwa ndi kumva kuwawa ndi kutentha. Zimalekerera molumikizana ndi zopangira mafuta. Kutentha kumachokera ku -40 mpaka +150 madigiri.
• HNBR - Kutentha Kwambiri Kuteteza Mphira (Hydrogenated Nitrile Butadiene Elastomer). Zinthuzo zimalekerera kukhudzana ndi mankhwala omwe amagwiritsidwa ntchito mgalimoto bwino. Kutengera kuchuluka kwa acrylonitrile, mankhwalawo amatha kupirira chisanu choopsa, koma nthawi yomweyo sichimalimbana ndi zovuta zamafuta. Kutentha kumakhala pakati pa -50 ndi +160 madigiri. Izi ndizinthu zodula kwambiri pamabotolo oyang'anira nthawi.

M'mabuku aukadaulo pamakina, mutha kupeza magawo ofunikira a mota inayake. Kuphatikiza pa geometry ya lamba, kuvala kwa mankhwala ndi chinthu chofunikira kwambiri. Mukamagula lamba watsopano, muyenera kuganizira izi:

• Iyenera kupirira katundu wolemera komanso mphamvu yayikulu;
• Ziyenera kusunga katundu wake, nthawi yachisanu komanso yotentha;
• Ziyenera kukhala zosagwira kuvala mwachangu;
• Mbiri ya mano sayenera kusintha mpaka kumapeto kwa moyo wautumiki;
• Ikatambasulidwa, siyenera kutaya katundu wake.

Poganizira zonsezi, muyenera kugula zinthu kuchokera kwa opanga odziwika bwino.

Mitundu yamalamba yanthawi

Tiyeni tiwone mwachidule mitundu yodziwika bwino ya malamba. Zonse pamodzi, pali zosintha zitatu pazinthu izi:

• Ndi mano;
• Mbiri yopangidwa ndi mphero;
• Mbiri yopangidwa ndi Poly-V.

Mu magalimoto amakono, malamba a nthawi amagwiritsidwa ntchito. Mitundu yotsala yamapulogalamu ilibe umboni wokha ngati malamba oyendetsa galimoto, koma mitundu yofananira imagwiritsidwa ntchito, mwachitsanzo, jenereta kapena kompresa.

Ponena za mawonekedwe a mano, palinso mitundu ingapo ya iwo. Aliyense wa iwo ali ndi makhalidwe ake, ndipo pa nthawi yomweyo cholinga chake. Makina wamba amagwiritsa ntchito lamba wokhala ndi mano otchedwa trapezoidal. Pali malamba okhala ndi mano ozungulira. Cholinga chawo ndikulumikiza magwiridwe antchito amphamvu kwambiri. Zida zamagetsi zotere zimakhala ndi makokedwe ambiri, omwe amatha msanga mano pa lamba wamba.

Kodi mungayang'ane liti nthawi?

Nthawi zambiri sikofunikira kuti muwone momwe lamba alili pafupipafupi. Pachifukwa ichi, kukonza magalimoto kumakonzedwa. Mndandanda wa ntchito panthawi iliyonse yothamanga umaphatikizapo ntchito zosiyanasiyana. Kamodzi panthawi yonse yantchito, kusintha kwa lamba kumachitika, ndipo nthawi yonseyi, oyang'anira amangoyang'ana momwe zinthu zilili ndi makina ena.

Cheke chosayembekezereka cha lamba woyendetsa amayenera kuchitidwa ngati kuwonongeka kwamagalimoto, mwachitsanzo, chitoliro chazizira chaphulika, ndipo zoletsa kuwuma zafika pagalimoto yoyendetsa nthawi. Pankhaniyi, patapita kanthawi kochepa, muyenera kuwunikanso momwe ziwalo zina za raba zathiridwira (kapena mafuta, ngati woyendetsa mwangozi adathira pa chipindacho). Mankhwala omwe amapanga antifreeze, mafuta amafuta ndi mafuta amatha kuwononga zopangira mphira.

Kutengera mtundu wa injini, mphamvu yake ndi mtundu wamagalimoto, kusintha kwa lamba kumachitika pambuyo pa ma kilomita 60-160 zikwi.

Chifukwa china chofufuzira pafupipafupi momwe zinthu zilili ndi pomwe galimoto imayambitsidwa kuchokera pa pusher. Poterepa, lamba amakhala ngati woyambira, zomwe sizabwinobwino gawo lotere, chifukwa mota ikagundidwa motere, pamakhala lamba wambiri kuposa nthawi yoyambira. Ichi ndi chifukwa chofunikira kuti batire liyenera kuyang'aniridwa (pakusamalira magetsi ndi magwiridwe ake oyenera, onani apa).

Momwe mungamvetse kuti muyenera kusintha lamba wa nthawi

Sizachilendo kuti lamba amamasuka osagwiritsa ntchito gwero lonse logwirira ntchito, ngakhale kuti wopanga amakhala ndi nthawi yayitali yolowetsa m'malo ake pang'ono. Pachifukwa ichi, malingaliro aopanga sindiwo njira yokhayo yomwe angatsatire.

Ngakhale kuyang'anitsitsa ndi njira yabwino kwambiri yowonetsetsa kuti lamba wa nthawi ali bwino, limatetezedwa ndi chovala. Chitetezo sichovuta kuchotsa nthawi zonse, chifukwa chake ndizothandiza kuyang'ana pazifukwa izi:

• Kuphatikiza pa mileage, zaka za malonda ndizofunikanso. Musagwiritse ntchito lamba yemwe wakhala pagalimoto zaka zopitilira 7 (izi zimachitika galimoto ikamayendetsa kawirikawiri). Zogulitsa za mphira zimakhala ndi tsiku lawo lothera, pambuyo pake mankhwalawo amataya katundu wake.
• Pamene malfunctions anayamba kuonekera mu dongosolo poyatsira, koma poyatsira palokha ntchito bwino. Izi zimatha kuoneka mano akamagundana ndi pulley. Ndi kulephera koteroko, galimotoyo imatha katatu (pazifukwa zina, werengani payokha) kapena ayi kuyamba konse.
• Kuwoneka kwadzidzidzi kwa utsi kuchokera ku chitoliro cha utsi.
