malamba a nthawi

Lamba wanthawi yabwino kapena lamba woyendetsa amakhala ndi nthawi yomwe zimatengera kuti amalize kuzungulira dziko lonse lapansi m'moyo wake wonse.

Lamba wabwino wokhala ndi mano kapena lamba woyendetsa galimoto amayenda mtunda wofanana ndi kusinthika kumodzi kuzungulira dziko lapansi m'moyo wake, ndipo mano a lamba wanthawi amagwira ntchito nthawi zambiri monga momwe kuli anthu padziko lapansi. Kumapeto kwa lamba, lamba ayenera kusinthidwa. Inde, ngati kuli kofunikira, lamba liyenera kusinthidwa kale.

Ku Ulaya kokha, malamba okwana 40 miliyoni amasinthidwa chaka chilichonse. Pachiwerengerochi chiyenera kuwonjezeredwa malamba oyendetsa (monga Multi-V) omwe amapezeka pagalimoto iliyonse. Malamba ndi gawo la ma pulleys, tensioners, zisindikizo ndi mapampu amadzi omwe nthawi zambiri amafunika kusinthidwa nthawi imodzi.

Lamba wanthawi ndi njira yachete komanso yopanda kugwedezeka yolumikizira ma valve ndi injini yonse. Tsopano ndizofunikira kwambiri ku injini kuposa kale lonse. Pafupifupi injini iliyonse yatsopano imakhala ndi kugunda komwe mavavu ndi ma pistoni amakhala pafupi. Lamba wanthawi yosweka kapena wosweka angayambitse pisitoni kugunda valavu yotseguka, kupangitsa mavavu kupindana, ma pistoni kuphulika, ndipo motero kuwonongeka kwakukulu kwa injini. Ngakhale injini zosagundana sizikuwonongeka mofanana ndi injini zosagunda, ngati lamba wa nthawi yalephera, woyendetsa amatha kukhala pambali ndi injini yolephera. Masiku ano, lamba wanthawi yake ndi gawo lofunikira kwambiri pakugawa gasi, komanso jekeseni ndi mapampu amadzi.

Lamba wa Multi-V ndi lamba woyendetsa wowonjezera ndizofala pamagalimoto opangidwa kuyambira chakumapeto kwa zaka makumi asanu ndi anayi. Amapereka kudalirika kwakukulu komanso mphamvu zambiri zolemetsa kuposa makanda akale a V. Pakubwera kwa chiwongolero cha mphamvu ndi mpweya, ma V-lamba ambiri akhala ofunika kwambiri pa ntchito yowonjezera. Pagalimoto yokhala ndi lamba wa Multi-V wowonongeka, chosinthiracho chikhoza kuwonongeka, chiwongolero champhamvu chikhoza kutayika, ndipo poyipa kwambiri, lambayo amatha kulowa mu dongosolo lanthawi.

Lamba kapena unyolo?

Kuyambira kukhazikitsidwa kwa lamba wa nthawi, ntchito yake yasintha chifukwa cha chitukuko cha zipangizo zatsopano ndi mawonekedwe a mano omwe amatha kupirira kutentha kwakukulu ndi mphamvu zambiri za injini. Mtundu uliwonse wa injini nthawi zambiri umakhala ndi lamba wake. M’zaka makumi angapo zapitazi, opanga magalimoto ambiri ku Ulaya asankha malamba a nthawi. Koma maunyolo a nthawi akubweranso, ndipo tsopano akupezeka mu 20% mpaka 50% ya injini zamakono zopangidwa ndi makampani a galimoto.

"Mwina opanga anali ndi vuto ndi ntchito zina zam'mbuyomu lamba ndipo maunyolo amatenga malo ochepa kutsogolo kwa injini. Komabe, m’malo mwa unyolo wa nthaŵi ndi unyolo wa nthaŵi nthaŵi zambiri kumafuna kuchotsedwa kwa injini ndi mbali yonse ya kutsogolo kwa injini, zimene zimafuna nthaŵi ndi ndalama zambiri malinga ndi mmene kasitomala amaonera,” anatero Maurice Foote, Woyang’anira Engine wa SKF. Ngakhale chingwe cha Multi-V chakhala chokhazikika, palibe zomangira zokhazikika. Pakhoza kukhala mitundu ingapo ya malamba oyendetsa mosiyanasiyana amtundu uliwonse wa injini. Zimatengera zida zomwe zimayikidwa pagalimoto. Kutalika kwa chingwe ndikofunika kwambiri - ngakhale mamilimita amaganiziridwa apa. Tiyerekeze kuti lamba woyambirira wa Multi-V wagalimoto ali ndi kutalika kwa mamilimita 1691. Ogulitsa ena atha kukupatsirani chingwe chachifupi ngati 1688mm, kunena kuti ndiutali wolondola wagalimoto yanu. Komabe, mamilimita atatu omwe akusowa angayambitse kugwedezeka kwakukulu kapena phokoso ndi kutsetsereka ngati sewerolo silili m'kati mwazovomerezeka za auto tensioner.

Mipikisano V-malamba

Lamba wa Multi-V amagwira ntchito m'malo ovuta. Nthawi zambiri amawonetsedwa ndi dothi, madzi ndi mafuta, ndipo galimoto yokhala ndi zida zabwino, kupanikizika kwambiri pa lamba kumawonjezeka.

Kuchita bwino kwa kayendedwe ka kayendedwe ka magalimoto kumatanthawuza kuchepa kwa mpweya ndi kutentha pansi pa hood, kapena monga momwe munganene, injini yochulukirapo m'malo ochepa. Ma injini amphamvu kwambiri omwe amathamanga kutentha kwambiri samapangitsa kuti ntchitoyi ikhale yosavuta. Izi ndizowona makamaka kwa lamba wanthawi. Mitsinje iwiri imatanthawuza malamba aatali, ndipo m'mimba mwake ma pulleys akucheperachepera, kupulumutsa malo. Ndipo, ndithudi, mbali zonse ziyenera kulemera pang'ono momwe zingathere.

Utumiki wovomerezeka wa malamba masiku ano ndi zaka 60. mpaka 150 km. Malamba ndi olimba mokwanira kuti athe kupirira ma torque apamwamba, komanso chifukwa cha kulimbitsa kwa fiberglass. Moyo wautumiki wa dongosolo lamba nthawi zonse umayesedwa pamakilomita oyendetsedwa. Ichi ndiye chinthu chachikulu, koma osati chokhacho. Palinso ena ochepa omwe angafupikitse moyo wa lamba - awiri otsatirawa ndi olimba kwambiri kapena omasuka kwambiri. Yoyamba imayambitsa kuvala ndi kulumpha kwa mano, ndipo yachiwiri imayambitsa kuvala ndi kuwonongeka kumbali ya lamba, zomwe zimapangitsa kuti pakhale kuvala kwa odzigudubuza ndi mayendedwe. Kugwedezeka, mafuta, mafuta kapena kutayikira kwamadzi, komanso dzimbiri ndizinthu zina zomwe zingafupikitse moyo wamakina anu.
