Ukushintsha ibhande lesikhathi iRenault Duster 2.0

Ukushintsha ibhande lesikhathi iRenault Duster 2.0 kuwumsebenzi onzima odinga amathuluzi engeziwe. Ngaphezu kwalokho, injini kaphethiloli engu-2-litre Renault Duster ayinawo amamaki wesikhathi kuma-pulleys e-camshaft, okwenza umsebenzi ube nzima. Ngokwezindinganiso zomkhiqizi, ibhande kufanele lishintshwe njalo ngamakhilomitha ayizinkulungwane ezingu-60 noma njalo eminyakeni emi-4, noma yikuphi okuza kuqala.

Ngaphambi kokuqala umsebenzi, udinga ukuqonda ukuthi le injini ayinawo amamaki okuqondanisa kuma-pulleys e-camshaft, ngakho-ke funda lesi sihloko ngokucophelela ukuze ama-valve angaguquki ngemva kokuhlanganisa okungalungile. Ukuze uqalise, bhekisisa i-Timing Duster 2.0 esithombeni esilandelayo.

Empeleni, ngaphezu kokushuba kanye nama-bypass rollers (angekho), i-pulley yepompo yamanzi (ipompo) nayo iyabandakanyeka kule nqubo. Ngakho-ke, lapho ushintsha ibhande, qiniseka ukuthi uhlola ipompo ukuze uthole amabala, ukudlala ngokweqile. Uma kunezibonakaliso ezimbi nezinsolo, ngaphezu kwebhande lesikhathi, futhi shintsha iphampu ye-Duster.

Ngaphambi kokuba uqale ukufaka esikhundleni ibhande futhi ususe izembozo, uzodinga ukususa ukukhweza injini. Kodwa ngaphambi kokuthi ususe iyunithi yamandla, udinga "ukuyilenga". Ukwenza lokhu, ibhulokhi yokhuni yafakwa phakathi kwe-crankcase kanye ne-subframe ukuze usekelo olufanele lweyunithi yamandla lungasakwazi ukusekela isisindo seyunithi. Ukuze wenze lokhu, usebenzisa ishidi lokufaka elibanzi, phakamisa kancane injini bese uyinamathisela esihlahleni, njengasesithombeni.

Sikhipha kubakaki ababekwe phezu kokwesekwa kwenjini yakwaRenault Duster, amapayipi okuhambisa uphethiloli kujantshi kanye nokuphakela umhwamuko kaphethiloli kumamukeli. Khipha ibakaki lezintambo zezintambo embobeni ekubakaki abasekelayo. Ngekhanda elithi “16”, qaqa izikulufu ezintathu ezivikela usekelo kukhava engaphezulu yesibambo sokusabalalisa. Usebenzisa ithuluzi elifanayo, qaqa izikulufu ezintathu ezivikela ubakaki emzimbeni. Susa ubakaki ongakwesokudla kuyunithi yamandla.

Manje sidinga ukufika ebhandeni. Ngekhanda elithi "13", siqaqa amabhawodi amathathu namantongomane abambe ikhava ephezulu yesikhathi. Susa ikhava yekesi lesikhathi eliphezulu.

Hlola ukungezwani kwebhande lesikhathi. Uma ufaka ibhande lesikhathi elisha, uzodinga ukulungisa kahle i-tensioner. Kulokhu, kunezimpawu ezikhethekile ku-tensioner roller.

Ngokucindezela okujwayelekile kwebhande, inkomba enyakazayo kufanele ihambisane nenothi kusikhombisi sesivinini sokungenzi lutho. Ukuze ulungise kahle ukungezwani kwebhande, uzodinga ukhiye kokuthi "10" kanye nokhiye we-hex kokuthi "6".

Uma ufaka ibhande elisha, khulula i-nati eliqinisayo le-tensioner roller nge-wrench "10" bese uphendulela i-roller clockwise nge-hexagon "6" (edonsa ibhande) kuze kube yilapho izinkomba ziqondana. Kodwa ngaphambi kwaleso sikhathi, kusadingeka ukhiphe ibhande elidala futhi ufake elisha.

Umcimbi wokuqala nobalulekile ukukhulula ibhawodi le-crankshaft pulley. Ukuze wenze lokhu, kuyadingeka ukuvimba ukufuduka kwe-pulley. Ungacela umsizi ukuthi ashintshe egiyeni lesihlanu futhi abambe amabhuleki, kodwa uma le ndlela ingasebenzi, kukhona okunye.

Sikhipha i-piston kuma-fasteners we-plastic bracket yezintambo zezintambo ukuya endlini ye-clutch. Susa ukusekela ngamahhanisi ezintambo kusukela endlini ye-clutch. Manje ungathatha isikrudrayiva esiyisicaba usinamathisele phakathi kwamazinyo egiya leringi ye-flywheel.

Ngokuvamile le ndlela isiza ukukhulula ibhawodi ngokushesha ngokwanele.

Ngekhanda elithi “8”, siqaqa izikulufi ezinhlanu ezibambe ikhava yesikhathi engezansi.

Ngaphambi kokukhipha ibhande lesikhathi, kuyadingeka ukusetha i-crankshaft nama-camshafts ku-TDC (isikhungo esiphezulu esifile) ekucindezelweni kwe-cylinder yokuqala. Manje sidinga ukuvimba i-crankshaft ukuthi ingajiki. Ukuze wenze lokhu, sebenzisa ikhanda le-E-14 ukuze uvule ipulaki ekhethekile yezobuchwepheshe ku-cylinder block.

Sifaka iphinikhodi yokulungisa emgodini we-cylinder block - induku enobubanzi obuyi-8 mm nobude okungenani obungama-70 mm (ungasebenzisa induku yokubhoboza enobubanzi obuyi-8 mm). Lokhu kuzovimba ukuphenduka kwe-crankshaft uma ukhipha ibhande le-timing iRenault Duster ngenjini engu-2 litre.

Uma i-crankshaft isendaweni ye-TDC yamapiston yesilinda 1st kanye ne-4th, umunwe kufanele ungene endaweni engunxande esihlathini se-crankshaft futhi uvimbe umgodi lapho uzama ukuwuphendulela ohlangothini olulodwa noma kwenye. Uma i-crankshaft isendaweni efanele, ukhiye ekugcineni kwe-crankshaft kufanele ube phakathi kwezimbambo ezimbili kukhava yekhanda yesilinda. Isithombe esilandelayo.

Ukuvimbela ukujikeleza kwama-camshafts, senza imisebenzi elandelayo. Ukuze uvimbele ama-camshafts, kuyadingeka ukususa amapulaki epulasitiki ngakwesokunxele kwekhanda le-cylinder. Kungani ususa i-resonator endleleni yomoya? Izigqoko zokugcina zepulasitiki zingabhobozwa kalula nge-screwdriver, nakuba uzodinga ukufaka ama-end caps kamuva.

Ngemuva kokukhipha ama-plugs, kuvela ukuthi iziphetho zama-camshafts zivaliwe. Esithombeni sibamaka ngemicibisholo ebomvu.

Lawa ma-grooves azosisiza ukuthi sivimbe ukujikeleza kwama-camshafts. Yiqiniso, kulokhu kuzodingeka wenze ipuleti ngesimo sohlamvu "P" ocezu lwensimbi. Ubukhulu bepuleti esithombeni sethu esingezansi.

Manje usungakwazi ukususa ibhande ngokuphepha bese ufaka elisha. Khulula inathi eliqinisayo ku-pulley ye-tensioner ngesikrufu esingu-10. Vula i-roller ngokuphambene newashi nge-hexagon "6", ukhulule ukungezwani kwebhande. Sisusa ibhande, siphinde siguqule ukungezwani kanye nama-roller asekelayo. Ibhande elisha kufanele libe namazinyo angu-126 nobubanzi obungu-25,4 mm. Lapho ufaka, qaphela imicibisholo esentanjeni - lezi yizikhombisi-ndlela zokuhamba kwebhande (ngokwewashi).

Lapho ufaka i-tension roller entsha, isiphetho esigobile sabakaki bayo kufanele singene endaweni yokuphumula ekhanda lesilinda. Bona isithombe ukuze uthole ukucaca.

Sifaka ibhande kuma-pulleys anamazinyo we-crankshaft nama-camshafts. Siqala igatsha elingaphambili lebhande ngaphansi kwepulley yepompo epholile, kanye negatsha elingemuva - ngaphansi kwe-tension kanye nama-roller asekelayo. Lungisa ukungezwani kwebhande lesikhathi (bona ngenhla). Sikhipha iphinikhodi yokulungisa emgodini we-cylinder block bese sisusa idivayisi yokulungisa ama-camshafts. Vula i-crankshaft izikhathi ezimbili ngokwewashi kuze kube yilapho ama-grooves ekugcineni kwama-camshaft asendaweni oyifunayo (bona ngenhla). Sihlola isikhathi se-valve kanye nokungezwani kwebhande futhi, uma kunesidingo, phinda izinguquko. Sifaka ipulaki enentambo endaweni yayo bese sicindezela amapulaki amasha ku-camshaft. Ukufakwa okwengeziwe kwenjini kwenziwa ngokulandelana okuphambene.
