Kusintha lamba wanthawi ya Renault Duster 2.0

Kusintha lamba wanthawi ya Renault Duster 2.0 ndi ntchito yovuta yomwe imafunikira zida zowonjezera. Komanso, 2-lita Renault Duster petulo injini alibe zizindikiro nthawi pa pulleys camshaft, amene ndithudi complicate ntchito. Malinga ndi miyezo ya wopanga, lambayo iyenera kusinthidwa makilomita 60 aliwonse kapena zaka 4 zilizonse, zilizonse zomwe zimabwera poyamba.

Musanayambe ntchito, muyenera kumvetsetsa kuti injini iyi ilibe zizindikiro zogwirizanitsa pazitsulo za camshaft, choncho werengani nkhaniyi mosamala kuti mavavu asagwedezeke pambuyo pa msonkhano wolakwika. Kuti muyambe, yang'anani mozama za Timing Duster 2.0 pachithunzi chotsatira.

M'malo mwake, kuwonjezera pazovuta komanso zodulira zodutsa (kulibe), pulley yamadzi (pampu) imakhudzidwanso ndi ntchitoyi. Chifukwa chake, mukamasintha lamba, onetsetsani kuti mwayang'ana pampu ya madontho, kusewera mopitilira muyeso. Pakakhala zizindikiro zoyipa ndi zokayikitsa, kuwonjezera pa lamba wanthawi, musinthenso pampu ya Duster.

Musanayambe kusintha lamba ndikuchotsa zophimba, muyenera kuchotsa kukwera kwa injini. Koma musanachotse mphamvu yamagetsi, muyenera "kuyipachika". Kuti tichite izi, chipika chamatabwa chinayikidwa pakati pa crankcase ndi subframe kotero kuti kuthandizira koyenera kwa magetsi sikungathe kuthandizira kulemera kwa unit. Kuti muchite izi, pogwiritsa ntchito pepala lalikulu, kwezani pang'ono galimotoyo ndikuyiyika pamtengo, monga pa chithunzi.

Timachotsa m'mabokosi omwe ali pa chithandizo cha injini ya Renault Duster, mapaipi operekera mafuta ku njanji ndi kupereka mpweya wamafuta kwa wolandira. Chotsani cholumikizira mawaya pabowo la bulaketi yothandizira. Ndi mutu wa "16", masulani zomangira zitatu zomwe zimatchinjiriza chothandizira pachivundikiro chapamwamba cha chogwirira cha ogawa. Pogwiritsa ntchito chida chomwecho, masulani zomangira zitatu zomwe zimatchinjiriza bulaketi ku thupi. Chotsani bulaketi yakumanja kugawo lamagetsi.

Tsopano tiyenera kufika lamba. Ndi mutu wa "13", timamasula mabotolo atatu ndi mtedza womwe umagwira chivundikiro chapamwamba cha nthawi. Chotsani chophimba chanthawi yayitali.

Onani kuthamanga kwa lamba wanthawi. Mukayika lamba watsopano wanthawi, muyenera kusintha bwino cholumikizira. Kwa ichi, pali zizindikiro zapadera pa tensioner roller.

Ndi kugwedezeka kwa lamba wamba, chizindikiro chosuntha chiyenera kugwirizana ndi notch mu chizindikiro chothamanga. Kuti musinthe bwino lamba, mufunika kiyi pa "10" ndi kiyi ya hex pa "6".

Mukayika lamba watsopano, masulani mtedza womangitsa wa chodzigudubuza cholumikizira ndi "10" wrench ndikutembenuzira chowotcha molunjika ndi "6" hexagon (kukoka lamba) mpaka zolozerazo zigwirizane. Koma nthawi imeneyo isanafike, muyenera kuchotsa lamba wakale ndi kuvala watsopano.

Chochitika choyamba komanso chofunikira ndikumasula bawuti ya crankshaft pulley. Kuti muchite izi, ndikofunikira kuletsa kusamuka kwa pulley. Mutha kufunsa wothandizira kuti asinthe ma giya achisanu ndikuyika mabuleki, koma ngati njira iyi siyikugwira ntchito, pali njira ina.

Timachotsa pisitoni kuchokera ku zomangira za pulasitiki za ma waya opangira ma waya kupita ku nyumba zolumikizirana. Chotsani chothandizira ndi ma wiring harnesses pa clutch house. Tsopano mutha kutenga screwdriver yathyathyathya ndikuyiyika pakati pa mano a mphete ya flywheel.

Kawirikawiri njirayi imathandiza kumasula bawuti mofulumira mokwanira.

Ndi mutu pa "8", timamasula zomangira zisanu zomwe zimagwira chivundikiro chapansi cha nthawi.

Musanayambe kuchotsa lamba nthawi, m'pofunika kukhazikitsa crankshaft ndi camshafts kuti TDC (pamwamba akufa pakati) pa psinjika sitiroko ya silinda yoyamba. Tsopano tiyenera kuletsa crankshaft kuti isatembenuke. Kuti muchite izi, gwiritsani ntchito mutu wa E-14 kuti mutulutse pulagi yapadera yaukadaulo pa block ya silinda.

Timayika pini yosinthira mu dzenje lachitsulo cha silinda - ndodo yokhala ndi mainchesi 8 mm ndi kutalika kwa osachepera 70 mm (mungagwiritse ntchito ndodo yobowola ndi mainchesi 8 mm). Izi zidzatsekereza kuzungulira kwa crankshaft mukasintha lamba wanthawi ya Renault Duster ndi injini ya 2 lita.

Pamene crankshaft ili pamalo a TDC a pistoni ya 1st ndi 4th silinda, chala chiyenera kulowa mumtsinje wa crankshaft ndi kutsekereza tsinde poyesa kutembenuza mbali imodzi kapena ina. Pamene crankshaft ili pamalo abwino, njira yolowera kumapeto kwa crankshaft iyenera kukhala pakati pa nthiti ziwiri pa chivundikiro chamutu cha silinda. Chithunzi chotsatira.

Kuti tiletse kuzungulira kwa camshafts, timachita zotsatirazi. Kuti aletse ma camshafts, ndikofunikira kuchotsa mapulagi apulasitiki kumapeto kumanzere kwa mutu wa silinda. N'chifukwa chiyani kuchotsa resonator panjira mpweya? Zipewa za pulasitiki zimatha kubooledwa mosavuta ndi screwdriver, ngakhale mudzafunika kuyika zipewa zatsopano pambuyo pake.

Pambuyo pochotsa mapulagi, zimakhala kuti malekezero a camshafts atsekedwa. Pachithunzichi timawalemba ndi mivi yofiira.

Ma groove awa adzatithandiza kuletsa kuzungulira kwa ma camshafts. Zowona, chifukwa cha izi muyenera kupanga mbale mu mawonekedwe a chilembo "P" kuchokera kuchitsulo. Miyeso ya mbale mu chithunzi chathu pansipa.

Tsopano mutha kuchotsa lamba mosamala ndikuvala watsopano. Masulani mtedza womangitsa pa tensioner pulley ndi 10 wrench. Tembenuzirani chodzigudubuza motsatana ndi hexagon "6", kumasula kulimba kwa lamba. Timachotsa lamba, timasinthanso zovuta ndi zodzigudubuza zothandizira. Lamba watsopano ayenera kukhala ndi mano 126 ndi m'lifupi mwake 25,4 mm. Mukayika, tcherani khutu ku mivi pazingwe - awa ndi njira zoyendetsera chingwe (molunjika).

Mukayika chodzigudubuza chatsopano, mapeto opindika a bulaketi yake amayenera kulowa mkatikati mwa mutu wa silinda. Onani chithunzi kuti mumveke bwino.

Timayika lamba pamapule a mano a crankshaft ndi camshafts. Timayamba nthambi yakutsogolo ya lamba pansi pa mpope woziziritsa, ndi nthambi yakumbuyo - pansi pa zovuta ndi zodzigudubuza. Sinthani mphamvu ya lamba wanthawi (onani pamwambapa). Timachotsa pini yosinthira ku dzenje la cylinder block ndikuchotsa chipangizo chokonzera ma camshafts. Tembenuzani crankshaft kawiri mozungulira mpaka ma grooves kumapeto kwa ma camshaft ali pamalo omwe mukufuna (onani pamwambapa). Timayang'ana nthawi ya valve ndi kuthamanga kwa lamba ndipo, ngati kuli kofunikira, kubwereza zosinthazo. Timayika pulagi ya ulusi m'malo mwake ndikusindikiza mapulagi atsopano pa camshaft. Kuyika kowonjezera kwa injini kumachitika motsatira dongosolo.
