Kusintha lamba woyendetsa: nthawi yowunika ndi momwe mungasinthire

Lamba woyendetsa womwe umagwiritsidwa ntchito mgalimoto imayendetsa mayunitsi othandizira a injini yoyaka yamkati. Chifukwa cha kuzungulira kwa crankshaft, imatumiza makokedwe, kuwonetsetsa kuti cholumikizacho chikugwira ntchito. Lamba woyendetsa ali gwero lake, zotalika mosiyanasiyana, nambala yosiyana ya mitsinje ndi mano. 

Yendetsani lamba ntchito

Lamba woyendetsa ndi wofunikira kuti utumize makokedwe kuchokera pa crankshaft, momwe magulu othandizira amathandizira. Kutumiza kwa makokedwe kumachitika chifukwa cha kukangana (poly V-lamba) kapena chinkhoswe (lamba wamoto). Kuchokera pagalimoto yoyendetsa lamba, ntchito ya jenereta idayambitsidwa, popanda zomwe sizingatheke kulipiritsa batri ndikukhalabe ndi voliyumu yanthawi zonse yapa bolodi. Makina oyendetsa mpweya komanso mpope wamagetsi amayendetsedwanso ndi lamba woyendetsa. Nthawi zina, mpope wamadzi umayendetsedwanso ndi lamba wamano (1.8 TSI VAG engine).

Moyo wautumiki wa malamba oyendetsa

Chifukwa cha kapangidwe kake (kusinthasintha komanso kusinthasintha), nthawi yayitali lamba ndi maola 25 kapena ma kilomita 000. Mwakuchita, moyo wamalamba umatha kusiyanasiyana mbali imodzi kapena ina, kutengera izi:

• khalidwe lamba;
• chiwerengero cha mayunitsi lotengeka ndi lamba umodzi;
• kuvala kwa crankshaft pulley ndi mayunitsi ena;
• lamba unsembe njira ndi mavuto zolondola.

Kuwunika pafupipafupi kwa malamba oyendetsa

Kufufuza kwakanthawi kwamakanda kumayenera kuchitika nyengo iliyonse. Kuzindikira kwamatenda kumachitika ndi injini. Mulingo wamavuto amayang'aniridwa ndikudina chala, pomwe kupatuka sikuyenera kukhala wopitilira masentimita 2. Kuwunika kowonekera kumawululira kupezeka kapena kupezeka kwa ming'alu. Powonongeka pang'ono, lamba ayenera kusinthidwa, apo ayi akhoza kuthyola nthawi iliyonse. 

Komanso, lamba amayang'anitsitsa pawokha:

• mtengo wokwanira wa batri;
• chiongolero (pamaso pa chiwongolero champhamvu) chidayamba kuzungulira mozungulira, makamaka nyengo yozizira;
• chowongolera mpweya chimazizira;
• Pogwira ntchito zamagulu othandizira, kumveka kulira, ndipo madzi akafika pa lamba, amatembenukira.

Nthawi komanso momwe mungasinthire lamba woyendetsa

Lamba woyendetsa uyenera kusinthidwa molingana ndi malamulo omwe amapanga, kapena pamaso pa zinthu zomwe zili pamwambazi. Moyo wocheperako wa malamba ndi 50000 km, kuvala ndi mtunda wocheperako kumawonetsa kubweza kwa imodzi mwamapuleti oyendetsa kapena kutsika kwa lamba.

Kutengera kusintha kwa injini ndi kapangidwe kazida zowonjezera, sinthani lamba nokha. Kusiyanitsa kuli pamtundu wamavuto:

• mavuto a bolt
• mavuto wodzigudubuza.

Komanso, mayunitsi akhoza lotengeka ndi lamba mmodzi, kapena payekha, mwachitsanzo: galimoto Hyundai Tucson 2.0 okonzeka ndi mpweya ndi mpope chiwongolero, aliyense amene ali lamba payekha. Lamba wa mpope wowongolera mphamvu umayendetsedwa kuchokera ku pulley ya jenereta, ndi chowongolera mpweya kuchokera ku crankshaft. Kuthamanga kwa lamba wa air conditioner kumachitika ndi chodzigudubuza, ndipo jenereta ndi mpope woyendetsa mphamvu ndi bawuti.

Njira yobwezeretsera malamba oyendetsa pogwiritsa ntchito chitsanzo cha Hyundai Tucson:

• injini iyenera kuzimitsidwa, chosankhira ma gearbox chiyenera kukhala mu "P" mode kapena mu 5th gear ndikunyamula dzanja;
• gudumu lakumanja lakumaso liyenera kuchotsedwa kuti lifike pa crankshaft pulley;
• kuti mupeze pulley ya KV, chotsani nsapato zapulasitiki zoteteza malamba ku dothi;
• Pansi pa hood, lamba wama pampu owongolera mphamvu ndiye woyamba kupeza, chifukwa cha izi muyenera kumasula chomangira ndikubweretsa mpope pafupi ndi injini;
• lamba wosinthira amachotsedwa ndikumasula zomangirazo, mofanana ndi pampu yoyendetsa magetsi;
• chomaliza chotsitsa lamba pa choletsa mpweya, apa vutoli limapangidwa ndi chozungulira, chomwe chimamangirizidwa pambali, kutengera kulimba kwa bolt, kulimba kwa lamba kumasinthidwa; Ndikokwanira kuti mutsegule chidacho ndi lamba ndikufooka;
• Kuyika malamba atsopano kumachitika mosiyana, ikani nsapato kumbuyo mutayang'ana momwe malamba akugwirira ntchito.

Samalani kwambiri za mtundu wazogulitsazo, yesani kugula zida zoyambirira, kuti mupewe chiopsezo chovala msanga.

Momwe mungayambitsire, kumangitsa kapena kumasula lamba woyendetsa

Pogwiritsa ntchito chitsanzo chomwecho:

• lamba wofewetsa amapanikizika ndi makina odzigwiritsira ntchito pogwiritsa ntchito bawuti yomwe imasunthira chozungulira; kuti kumangitsa bawuti, kutembenukira mobwerera, kumasula izo counterclocklock (kupatuka kwa lamba watsopano ndi zosaposa 1 cm);
• lamba wa alternator umamangirizidwa ndi cholembera chapadera, utachimangiriza, chosinthacho chimabwerera mmbuyo, ndikupangitsa mavuto, mbali ina lamba wafooka
• kumangitsa kapena kumasula lamba chiwongolero pampu mphamvu, muyenera kumasula msonkhano wokwera bawuti, kusankha kukankha chofunika ndi kumangitsa bawuti, ngati palibe kukanikiza kokwanira, ntchito phiri ndi kupuma pakati pa injini ndi mpope, kusuntha mpope. kutsogolo kulunjika galimoto.

Chifukwa chiyani lamba adaimba mluzu

 Kulira kwa belu kumachitika pazifukwa izi:

• Mukamayendetsa, madzi adafika pamalamba, kutembenukira poyerekeza ndi pulley;
• Kulephera kwa mayendedwe a jenereta kapena mpope wamagetsi, kuwonjezera katundu pa lamba;
• kusamvana kokwanira kapena mosinthanitsa;
• mankhwala osauka.

Ngati malamba ali bwino, koma squeak imachitika nthawi ndi nthawi, tikulimbikitsidwa kugula chopopera chopopera chomwe chimalimbitsa lamba, kukulitsa moyo wake wautumiki.

Mafunso ndi Mayankho:

Ndiyenera kusintha liti lamba wagalimoto? Izi zikhoza kutsimikiziridwa ndi chikhalidwe chakunja cha lamba. Chinthu chong'ambika chimakhala ndi ming'alu yaing'ono ingapo ndipo nthawi zina chikhoza kukhala chophwanyika.

Kodi kusintha lamba woyendetsa galimoto? Dzimbiri ndi ming'alu zawoneka, kubereka kwatha (kumayimba mluzu panthawi yogwira ntchito), nthawi ya valve yasuntha (lamba wafooka kwambiri).

Kodi ndikufunika kusintha lamba woyendetsa? Moyenera. Izi zimapereka kulumikizana pakati pa crankshaft ndi makina ogawa gasi ndi jenereta. Lambayo akathyoka, galimotoyo sichitha ndipo nthawi zina ma valve amapindika.
