Kusintha lamba wanthawi ya Volkswagen Passat b5

1996 chinali chiyambi cha kupanga "Volkswagen Passat B5" ku Ulaya, patapita zaka ziwiri galimoto anayamba kupangidwa mu America. Chifukwa cha zoyesayesa za opanga zodetsa nkhawa, galimotoyo yakhala yotsogola kwambiri pakupanga, mawonekedwe agalimoto afika pafupi ndi zitsanzo "zapamwamba". Magawo amagetsi a Volkswagen ali ndi lamba woyendetsa nthawi, kotero zingakhale zothandiza kwa eni ambiri a magalimoto awa kudziwa momwe Passat B5 amasinthira nthawi.

Za injini

Mitundu yosiyanasiyana ya injini zamtunduwu ili ndi mndandanda wochititsa chidwi, womwe umaphatikizapo mayunitsi amagetsi omwe amayendetsa mafuta ndi dizilo. Voliyumu yake yogwira ntchito imachokera ku 1600 cm 3 mpaka 288 cm 3 pazosankha zamafuta, 1900 cm 3 pa injini za dizilo. Chiwerengero cha masilindala ogwira ntchito a injini mpaka 2 cm 3 ndi anayi, makonzedwewo ali pamzere. Injini ndi voliyumu oposa 2 zikwi masentimita 3 ndi masilindala 5 kapena 6 ntchito, iwo zili pa ngodya. The awiri pisitoni injini mafuta ndi 81 mm, dizilo 79,5 mm.

Chiwerengero cha mavavu pa silinda akhoza kukhala 2 kapena 5, malinga ndi injini kusinthidwa. Mphamvu ya injini ya petulo imatha kuyambira 110 mpaka 193 hp. Ma injini a dizilo amakula kuchokera ku 90 mpaka 110 hp. Ma valve amayendetsedwa ndi lamba wa mano, kupatulapo injini ya TSI, yomwe ili ndi unyolo mumakina. Chilolezo cha kutentha kwa makina a valve chimayendetsedwa ndi ma compensators a hydraulic.

Njira yosinthira pagalimoto ya AWT

Kusintha lamba wa nthawi pa Passat B5 ndi ntchito yovuta, chifukwa kuti mumalize muyenera disassemble kutsogolo kwa galimoto. Mapangidwe ang'onoang'ono a chipinda cha injini sikukulolani kuti musinthe lamba mugalimoto ya valavu popanda izo.

Ntchito yokonzekera ikhoza kuchitidwa m'njira ziwiri, ndiko kusamutsa mbali yakutsogolo ndi "TV" kumayendedwe autumiki, kapena kuchotsa gawoli ndi bampu, nyali zakutsogolo, rediyeta.

AVT injini

Ntchito imayamba ndikudula mabatire kuti mupewe "zolakwika" mwangozi panthawi yogwira ntchito. Zidzakhala zokwanira kusagwirizana ndi terminal yolakwika ya batri. Chotsatira, muyenera kuthyola grille kutsogolo kwa radiator, imamangiriridwa ndi zomangira ziwiri, zokhazikika ndi latches. Komanso nthawi yomweyo muyenera kuchotsa chogwirira chotsegulira hood, loko yake. Izi zidzamasula malo ochulukirapo mu chipinda cha injini. Grill ya radiator imachotsedwa poyikoka.

Pambuyo pake, kupeza zomangira zinayi zomwe zimateteza bumper zimatsegulidwa, ndipo zomangira 4 zodzigonjetsera zimachotsedwa pansi pa phiko lililonse. Pa bampa yochotsedwa, zomangira 5 zina zimawonekera zomwe zikufunika kumasulidwa. Chotsatira ndikuchotsa nyali, iliyonse ili ndi zomangira 4 zomangira. Zomangira zakunja zimakutidwa ndi mapulagi a rabara, cholumikizira chokhala ndi zingwe zamphamvu zapamutu chimachotsedwa kumbuyo kwa nyali yakumanzere. Mpweya wa mpweya, womwe umagwiridwa ndi zomangira zitatu zodzigunda, uyenera kuthyoledwa.

Chiwembu chokhalitsa

Ma amplifiers amangiriridwa ndi ma bolts atatu ndi nati ya "TV" kumbali zonse, timamasula. Chotsatira ndikuletsa sensa ya A / C. Kuti muchotse radiator kuchokera ku air conditioner, muyenera kupeza ma studs kuti mukonze. Pambuyo pake, radiator imachotsedwa, ndi bwino kuchotsa mapaipi kuchokera ku injini ya injini kuti asawononge radiator. Kenako chotsani sensa ndi zitoliro zowongolera mphamvu zowongolera mphamvu. Pambuyo pake, gawo la zoziziritsa kukhosi limatsanuliridwa mu chidebe chopanda kanthu.

Paipi yokwanira bwino imayikidwa pa chitoliro chokhetsa, phulalo limachotsedwa ndipo madziwo amathiridwa. Mukamaliza ntchito izi, mukhoza kusuntha kapena kuchotsa kwathunthu "TV" pamlanduwo, zomwe zimalepheretsa kupeza nthawi. Kuti muchepetse zovuta panthawi yosonkhanitsa, zizindikiro zimayikidwa pa nyumba yopangira magetsi ndi shaft yake, pambuyo pake ikhoza kupasuka. Tsopano mutha kuchotsa tensioner ndi lamba wowongolera mpweya. Chotsitsimutsa chimakankhidwira mmbuyo ndi wrench yotseguka mpaka "17", yokhazikika pamalo okhazikika ndipo lamba amachotsedwa.

Kuphatikiza apo, ndondomekoyi ingakhale ngati iyi:

• Chitetezo cha pulasitiki cha nthawiyo chimachotsedwa, chifukwa cha izi zingwe zapambali za chivundikiro zimasweka.
• Pamene crankshaft ya injini ikuzungulira, zizindikiro zogwirizanitsa zimagwirizanitsidwa. Zizindikiro zimayikidwa pamwamba ndi pansi pa lamba, ndizofunikira kuwerengera chiwerengero cha mano pa lamba kuti akhazikitse bwino gawo latsopano. Payenera kukhala 68 mwa iwo.

TDC crankshaft

• Pulley ya crankshaft imasokonekera, bolt yambali khumi ndi iwiri siyenera kuchotsedwa, zomangira zinayi sizimachotsedwa.

Kuchotsa crankshaft pulley

• Tsopano chotsani m'munsi ndiyeno zotchingira zapakati zoteteza ku nthawi yoyendetsa.
• Pang'onopang'ono, popanda kusuntha kwadzidzidzi, ndodo yododometsa imamizidwa, pambuyo pake imakhazikika m'derali, lamba akhoza kutha.

Moyo wautumiki wa malamba makamaka umadalira luso la injini. Kuchita kwake kumakhudzidwa kwambiri ndi kulowetsa kwamadzimadzi aukadaulo kumalo ogwirira ntchito, makamaka mafuta a injini. Ma injini a Passat mu "zaka" zawo nthawi zambiri amakhala ndi mafuta a injini kuchokera pansi pa crankshaft, camshaft ndi countershaft mafuta seals. Ngati mafuta akuwoneka pa cylinder block m'dera la shafts, zisindikizo ziyenera kusinthidwa.

Musanayike gawo latsopano lopuma, fufuzaninso malo a zizindikiro zoyikapo, momwe ma valve oyendetsera nthawi alili. Ikani lamba watsopano pa crankshaft, camshaft ndi ma pump pulleys. Onetsetsani kuti pali mano 68 pakati pa zilemba za kumtunda ndi pansi. Ngati zonse zachitika molondola, ndiye limbitsani lamba wa nthawi. Pambuyo pake, muyenera kutembenuza crankshaft ya injini kutembenukira kuwiri, fufuzani zochitika zofananira ndi zizindikiro zoikamo. Komanso, zida zonse zomwe zidaphwasulidwa m'mbuyomu ndi zazikulu zimayikidwa m'malo awo.

Zizindikiro zoyika

Iwo ndi ofunikira pakuyika kolondola kwa nthawi ya valve ya mphamvu yamagetsi kuti zitsimikizire kuti zikugwira ntchito bwino. Kuti muchite izi, tembenuzirani mutu wa zomangira khumi ndi ziwiri za crankshaft mpaka zidziwitso za pulley ya camshaft zigwirizane ndi zotchingira nthawi. Pulley ya crankshaft ilinso ndi zoopsa zomwe ziyenera kukhala zotsutsana kwambiri ndi chizindikiro cha silinda. Izi zimagwirizana ndi malo pomwe pisitoni ya silinda yoyamba ili pamwamba pakatikati pakufa. Pambuyo pake, mukhoza kuyamba kusintha lamba wa nthawi.

Zizindikiro za camshaft ndi crankshaft

Kuvuta kwa lamba

Osati moyo wautumiki wa lamba woyendetsa, komanso magwiridwe antchito amtundu wonse wapadziko lonse lapansi zimadalira kuchitidwa kolondola kwa ntchitoyi. Akatswiri amalangiza kusintha tensioner pa nthawi yomweyo lamba nthawi. Lamba wanthawi Passat B5, wokwera pamapule, amamangika motere:

• The tensioner eccentric imatembenuzidwa motsutsana ndi wotchi pogwiritsa ntchito wrench yapadera kapena zozungulira mphuno kuti achotse zoyezera zokhoma mpaka choyimitsa chitha kuchotsedwa.

Magetsi wodzigudubuza

• Kenako tembenuzirani eccentric mozungulira mpaka 8 mm kubowola pang'ono kulowetsedwa pakati pa thupi ndi cholumikizira.

Kuvuta kwa lamba

• Wodzigudubuza amakhazikika pamalo awa, kenako ndikumangitsa mtedza wokonza. Mtedza umakonzedwa ndi choyimitsa ulusi usanakhazikitsidwe.

Kusintha kwa Tension Part 2

Ndi chida chiti chogulira

Moyenera, kupeza zida zosinthira bwino kuposa zoyambirira ndizosatheka. Kutalika kwa magawo otumizira nthawi kumadalira kwambiri mtundu wa magawowo. Ngati pazifukwa zina sizingatheke kukhazikitsa zida zoyambirira. Mukhoza kuchita zotsatirazi. Zogulitsa za DAYCO, Gates, Contitech, Bosch zatsimikizira. Posankha mbali yoyenera yopuma, muyenera kusamala kuti musagule fake.
