Zizindikiro za Lamba Wanthawi Yolakwika kapena Wolephera

Zizindikiro zodziwika bwino zimaphatikizirapo phokoso lomwe limachokera ku injini, injini yomwe siyaka, moto wolakwika, komanso kutayikira kwamafuta a injini isanayambike.

Lamba wanthawi ndi gawo la injini yamkati yomwe imazungulira kamera ya injini ndi crankshaft mu synchrony ndikuwonetsetsa kuti silinda iliyonse imayaka nthawi yoyenera. Lamba wanthawiyo amakhala pansi pa chivundikiro cha nthawi ndipo ali kutsogolo kwa injini. Nthawi zambiri amapangidwa kuchokera ku mphira wapamwamba kwambiri wokhala ndi zingwe zolimba za nayiloni mkati kuti atalikitse moyo wa lamba. Komabe, imakhudzidwa ndi mphamvu zodabwitsa mkati mwa injini yanu ndipo pamapeto pake iyenera kusinthidwa. Popanda lamba wogwira ntchito mokwanira, injini yanu siyiyamba.

Si injini zonse zomwe zili ndi lamba wanthawi. Lamba wanthawiyo amagwiritsidwa ntchito kwambiri pamagalimoto ndi ma SUV okhala ndi mainjini ang'onoang'ono. Injini ikakhala ndi chobowola chachikulu ndi sitiroko, opanga magalimoto ambiri amagwiritsa ntchito lamba wa raba m'malo mwake ndi unyolo wachitsulo. Unyolo wa nthawi nthawi zambiri umatenga nthawi yayitali kuposa malamba a nthawi, ndipo ena amapangidwa kuti azikhala moyo wagalimoto. Opanga magalimoto ambiri amakonzeratu malingaliro oti alowe m'malo mwa lamba wanthawi, koma pali zizindikiro zochepa zosonyeza kuti pali vuto.

Pansipa pali zizindikiro zodziwika bwino zomwe zingasonyeze kuti lamba wanu wanthawi yayitali wavala kapena kuthyoka, zomwe zingafune kuti lamba wanthawiyo alowe m'malo ndi makina ovomerezeka a ASE am'deralo ndi zida zina zamkati za injini zomwe zidawunikiridwa kuti ziwonongeke.

1. Phokoso loyimitsa lochokera ku injini

Lamba wanthawiyo amamangiriridwa ndi ma pulleys angapo ku crankshaft ya injini ndi camshaft. Crankshaft imayendetsa ndodo zolumikizira injini, zomwe zimamangiriridwa ku pistoni mkati mwa chipinda choyaka moto. Camshaft imayang'anira ma valavu amutu wa silinda ndi gulu la rocker arm, lomwe limawongolera mafuta m'chipinda choyaka ndikutulutsa mpweya wowotcha kuchokera kumagetsi ambiri. Lamba wa nthawi akayamba kutha, amatha kutulutsa mawu ogunda mkati mwa injini. Chizindikiro chochenjezachi chikhoza kuwonetsanso kuchepa kwa mafuta kapena mafuta osakwanira mu injini.

Popeza lamba wa nthawi ndi wofunika kwambiri pakugwira ntchito kwa galimoto yanu, ngati muwona chizindikiro chochenjeza, muyenera kulankhulana ndi makaniko anu mwamsanga.

2. Injini siyiyamba

Ngati lamba wanthawiyo wathyoledwa mkati, injiniyo sichitha kutembenuka kapena kugwira moto. Mukatembenuza kiyi, mutha kumva woyambitsa akutenga nawo mbali, koma chifukwa lamba wanthawiyo amayendetsa crank ndi camshaft, silingatembenuke. Mwachiwonekere, ngati galimoto siimayamba, kuyitana makaniko nthawi zambiri ndi sitepe yoyamba. Komabe, ngati vutoli likukhudzana ndi lamba wosweka nthawi, lingayambitsenso kuwonongeka kwina kwa mkati mwa chipinda cha injini. Nthawi zambiri, lamba wanthawiyo amaduka injini ikugwira ntchito. Zina mwazowonongeka zomwe zimachitika pagalimoto yokhala ndi lamba wosweka nthawi zimaphatikizira kuwonongeka kwa zida za silinda (mikono ya rocker, pushrods, kapena mavavu), kuwonongeka kwa ma crank bearings, kapena kuwonongeka kwa mpope wamafuta mkati mwa poto yamafuta.

Katswiri wamakaniko komanso wodziwa zambiri amadziwa momwe angayang'anire zida zonsezi ngati lamba wanthawi ayenera kusinthidwa.

3. Kusokonekera kwa injini

Lamba wanthawi yayitali amathanso kukhudza liwiro la injini. Lamba wanthawiyo amamangiriridwa ku ma pulleys omwe amayendetsa crank ndi camshaft monga tawonetsera pamwambapa. Komabe, nthawi zina lamba amatsika pagalimoto ya camshaft ndikupangitsa kuti silinda imodzi itseguke kapena kutseka msanga kuposa momwe iyenera kukhalira. Izi zingayambitse kuombera molakwika ndipo, ngati sizisinthidwa posachedwa, zitha kuwononga injini kwambiri.

4. Kutuluka kwamafuta kutsogolo kwa injini

Ndizofanananso kuti injini itaya mafuta a injini kuchokera pachivundikiro cha lamba wanthawi. Chophimbacho chimagwiridwa ndi mndandanda wa mtedza ndi bolts, zomwe zimatha kumasula pakapita nthawi. Vuto linanso lomwe lingapangitse kuti mafuta atayike ndi pamene gasket pakati pa chipika cha injini ndi chivundikiro cha nthawi yatha, kusweka, kapena kuikidwa molakwika ndikumangika. Kutuluka kwamafuta kuchokera pachivundikiro cha lamba wanthawi kumabweretsanso kutenthedwa kwa injini komanso kuvala lamba wanthawi isanakwane.

Nthawi zambiri zimakhala zovuta kuwona vuto la lamba wanthawi yayitali mpaka itachedwa kwambiri ndipo idasweka. Komabe, muyenera kufunsana ndi wopanga galimoto yanu kuti mudziwe nthawi yoti mulowe m'malo mwake ndikusintha lamba wanu ndi katswiri wamakaniko.
