Ukushintshwa kwebhande lesikhathi leVolkswagen Passat b5

Ngo-1996 kwaqala ukukhiqizwa kweVolkswagen Passat B5 eYurophu, ngemva kweminyaka emibili imoto yaqala ukukhiqizwa eMelika. Ngenxa yemizamo yabaklami bokukhathazeka, imoto isithuthuke kakhulu ekukhiqizeni, isimo semoto sesisondele kumamodeli "okunethezeka". Amayunithi kagesi akwaVolkswagen ane-timing belt drive, ngakho kuzoba usizo kubanikazi abaningi balezi zimoto ukwazi ukuthi ishintshwa kanjani iPassat B5 timing.

Mayelana nezinjini

Uhlu lwezinjini lwale modeli lunohlu oluhlaba umxhwele, oluhlanganisa amayunithi amandla asebenza kuphethiloli nodizili. Ivolumu yayo yokusebenza isukela ku-1600 cm 3 kuya ku-288 cm 3 ngezinketho zikaphethiloli, 1900 cm 3 ezinjini zikadizili. Inani lamasilinda asebenzayo ezinjini afinyelela ku-2 3 cm 2 anezine, ilungiselelo liku-line. Izinjini ezinomthamo ongaphezu kuka-3 5 cm 6 zinamasilinda asebenzayo angu-81 noma angu-79,5, atholakala nge-engeli. Ububanzi bepiston yezinjini zikaphethiloli buyi-XNUMX mm, kudizili XNUMX mm.

Inani lama-valve ngesilinda lingaba ngu-2 noma 5, kuye ngokuguqulwa kwenjini. Amandla ezinjini zikaphethiloli angasukela ku-110 kuye ku-193 hp. Izinjini zikadizili zisuka ku-90 ziye ku-110 hp. Ama-valve ashayelwa ibhande elinamazinyo, ngaphandle kwenjini ye-TSI, eneketango emshinini. Ukukhishwa okushisayo kwe-valve mechanical kulawulwa yizinxephezelo ze-hydraulic.

Inqubo yokushintshwa kumoto ye-AWT

Ukushintsha ibhande lesikhathi kuPassat B5 kuwumsebenzi onzima, ngoba ukuze uliqedele udinga ukuqaqa ingaphambili lemoto. Idizayini ehlangene yegumbi lenjini ngeke ikuvumele ukuthi ushintshe ibhande ku-valve train drive ngaphandle kwalo.

Umsebenzi wokulungiselela ungenziwa ngezindlela ezimbili, lokhu ukudlulisa ingxenye engaphambili nge "TV" kumodi yesevisi, noma ukususa ngokuphelele le ngxenye ngebhampa, izibani, irediyetha.

Injini ye-AVT

Umsebenzi uqala ngokunqamula amatheminali ebhethri ukugwema "amaphutha" ephutha ngesikhathi sokusebenza. Kuzokwanela ukunqamula itheminali enegethivu yebhethri. Okulandelayo, udinga ukudiliza i-grille phambi kwe-radiator, iboshwe ngezikulufo ezimbili, ezilungiswe ngama-latches. Futhi ngesikhathi esifanayo udinga ukususa isibambo sokuvula i-hood, ukukhiya kwayo. Lokhu kuzokhulula isikhala esengeziwe ekhomishini yenjini. I-radiator grill isuswa ngokuyidonsa.

Ngemuva kwalokho, ukufinyelela kuzikulufu ezine ezivikela ibhampa kuyavulwa, futhi izikulufi ezi-4 zokuzithinta ziyakhishwa ngaphansi kwephiko ngalinye. Kubhampa okhishiwe, kuyabonakala ezinye izikulufu ezi-5 ezidinga ukukuluhlwa. Isinyathelo esilandelayo ukususa izibani, ngayinye yazo inezikulufu ezi-4 zokubopha. Izikulufu zangaphandle zimbozwe ngamapulaki enjoloba, isixhumi esinezintambo zamandla ezikhanyisa phezulu sinqanyuliwe ngemuva kwesibani sesokunxele. Ipayipi lomoya, elibanjwe izikulufu ezintathu ezizishayayo, kufanele liqaqwe.

Uhlelo lwesikhashana

Ama-amplifiers ama-bumper aboshwe ngamabhawodi amathathu kanye ne-"TV" yokufaka nati ohlangothini ngalunye, siyayiqaqa. Isinyathelo esilandelayo ukukhubaza inzwa ye-A/C. Ukuze ususe i-radiator ku-air conditioner, udinga ukuthola izigxobo zokuyilungisa. Ngemuva kwalokho, i-radiator isusiwe, kungcono ukunqamula amapayipi enjini ukuze ungalimazi i-radiator. Bese unqamula inzwa kanye nezinsimbi zamapayipi okupholisa isiteringi samandla. Ngemva kwalokho, ingxenye yesipholisi ithululelwa esitsheni esingenalutho.

I-hose enobubanzi obufanele ifakwa epayipini lokudonsa amanzi, isikulufu asifinyeziwe futhi uketshezi luyakhishwa. Ngemva kokuqeda le misebenzi, ungakwazi ukususa noma ukususa ngokuphelele "i-TV" kukesi, okuvimbela ukufinyelela kumshini wesikhathi. Ukuze unciphise ukuhlupheka ngesikhathi somhlangano, amamaki abekwe phezu kwezindlu ze-impeller kanye ne-shaft yayo, emva kwalokho ingahlakazwa. Manje usungakwazi ukususa i-tensioner kanye nebhande le-air conditioning. I-tensioner idudulwa emuva ngesikrufu esivulekayo siye ku-"17", simiswe esimweni sokuhlehla futhi ibhande liyasuswa.

Ngaphezu kwalokho, inqubo ingaba kanje:

• Ukuvikelwa kwepulasitiki kwesikhathi kuyasuswa, ngenxa yalokhu ama-latches ezinhlangothini zekhava aphukile.
• Uma i-crankshaft yenjini izungeza, amamaki okuqondanisa ayahambisana. Amamaki abekwe phezulu nangaphansi kwebhande, ayadingeka ukubala inani lamazinyo ebhande ukuze kufakwe kahle ingxenye entsha yokufaka esikhundleni. Kufanele kube nama-68 awo.

I-TDC crankshaft

• I-crankshaft pulley iyahlakazwa, ibholidi enamaceleni ayishumi nambili ayidingi ukususwa, izikulufu ezine azikhohliwe.

Ukukhipha i-crankshaft pulley

• Manje susa isembozo sokuvikela esiphansi bese usiba phakathi kudrayivu yesikhathi.
• Ngomusa, ngaphandle kokunyakaza okungazelelwe, induku ye-shock absorber icwiliswa, emva kwalokho ilungiswe kulesi simo, ibhande lingahlukaniswa.

Impilo yesevisi yamabhande incike kakhulu esimweni sobuchwepheshe benjini. Ukusebenza kwayo kuthinteka kakhulu ngokungena kwamanzi obuchwepheshe endaweni yokusebenza, ikakhulukazi uwoyela wenjini. Izinjini ze-Passat "eminyakeni" yazo zivame ukuba nama-smudges kawoyela wenjini asuka ngaphansi kwe-crankshaft, i-camshaft ne-countershaft oil seals. Uma iminonjana kawoyela ibonakala ku-cylinder block endaweni yale shafts, izigxivizo kufanele zishintshwe.

Ngaphambi kokufaka ingxenye entsha eyisipele, phinda uhlole indawo yezimpawu zokufaka, isimo somlawuli wesikhathi se-valve. Faka ibhande elisha ku-crankshaft, i-camshaft nama-pulleys epompo. Qiniseka ukuthi kunamazinyo angama-68 phakathi kwezimpawu zokuqondisa ezingaphezulu neziphansi. Uma konke kwenziwa ngendlela efanele, qinisa ibhande lesikhathi. Ngemva kwalokho, udinga ukuvula crankshaft injini izikhathi ezimbili, hlola ukuqondana amamaki ukufakwa. Futhi, zonke izinto ezahlakazwa ngaphambilini kanye nemihlangano emikhulu ifakwa ezindaweni zazo.

Izimpawu zokufaka

Ziyadingeka ukuze kufakwe kahle isikhathi se-valve yeyunithi yamandla ukuze kuqinisekiswe ukusebenza kwayo kahle. Ukwenza lokhu, vula ikhanda lesikulufu se-crankshaft esinezinhlangothi eziyishumi nambili kuze kube yilapho izimpawu ze-camshaft pulley ziqondana namamaki wekhava yesikhathi. I-crankshaft pulley iphinde ibe nezingozi okufanele zibhekane ngokuqinile nophawu olukubhulokhi yesilinda. Lokhu kuzohambisana nendawo lapho i-piston yesilinda sokuqala isendaweni ephezulu efile. Ngemva kwalokho, ungaqala ukushintsha ibhande lesikhathi.

Ukungezwani kweBelt

Hhayi kuphela impilo yesevisi yebhande lokushayela, kodwa futhi ukusebenza kwayo yonke indlela yokudlulisela iyonke kuncike ekusebenzeni kahle kwalo msebenzi. Ochwepheshe batusa ukushintsha i-tensioner ngesikhathi esifanayo nebhande lesikhathi. Ibhande lesikhathi i-Passat B5, elifakwe kuma-pulleys, liqiniswe ngale ndlela:

• I-tensioner eccentric iphendulwa ngokuphambene newashi kusetshenziswa isikrufu esikhethekile noma impumulo yekhala eliyindilinga ukuze kukhishwe amageji okukhiya kuze kukhishwe isivalo.

Amaphaphu roller

• Bese uphendulela i-eccentric ngokwewashi kuze kube yilapho kufakwa i-drill bit engu-8 mm phakathi komzimba kanye ne-tensioner.

Ukungezwani kwebhande okubuthakathaka

• I-roller igxilile kulesi sikhundla, ilandelwa ukuqinisa i-nati yokulungisa. I-nati icutshungulwa ngesivalo sentambo ngaphambi kokufakwa.

Iyiphi ikhithi okufanele uyithenge

Ngokufanelekile, ukuthola izingxenye ezisele ezingcono kunezokuqala cishe akunakwenzeka. Ibanga lezingxenye zokudlulisa isikhathi lincike kakhulu kwikhwalithi yezingxenye. Uma ngesizathu esithile kungenakwenzeka ukufaka ikhithi yokuqala. Ungenza lokhu okulandelayo. Imikhiqizo ye-DAYCO, Gates, Contitech, Bosch izibonakalise yona. Lapho ukhetha ingxenye eyisipele efanelekile, udinga ukuqaphela ukuthi ungathengi inkohliso.
