Kugwedeza malamba oyendetsa injini - ndi zabwinobwino kapena ayi?

Pafupifupi dalaivala aliyense wakumana ndi phokoso losasangalatsa lochokera pa lamba woyendetsa galimoto atayambitsa injini yozizira ndikuyamba. Komabe, kulira kwapamwamba sikumawonetsa kulephera komwe kukubwera: nthawi zambiri kumachepa mofulumira. Komabe, kugwedeza kosalekeza kwa lamba kuyenera kukhala kodetsa nkhawa mosasamala kanthu za kuyendetsa galimoto.

Ndi kunjenjemera kodzisangalatsa

Chifukwa chiyani lamba wowonjezera wa injini umapanga phokoso poyambitsa ndikusintha magiya? Funsoli likuyankhidwa ndi zomwe zimatchedwa chiphunzitso cha self-oscillations, chomwe chimafotokoza njira yopangira oscillations nthawi zonse, imamveka ngati phokoso lopweteka. Zikuoneka kuti omalizawo amapangidwa popanda kulowetsedwa kwa chinthu chakunja (iwo amasangalala okha) ndipo amadalira makhalidwe a lamba pulley system. Komabe, kugwedezeka uku ndi kwa nthawi yochepa, chifukwa pambuyo poonjezera liwiro la galimoto, iwo amatha ndipo amasiya kumveka (kumveka) pamene akuyendetsa galimoto. Kupatulapo ndi pamene lamba amayamba kugwedezeka pamene akuyendetsa pamtunda wonyowa. Pachifukwa ichi, phokoso losasangalatsa limayamba chifukwa cha chinyezi pamwamba pa lamba, zomwe, komabe, zimatuluka msanga chifukwa cha kutsetsereka, ndipo phokoso lalikulu limatha.

Ndi liti pamene squeaks imakhala yowopsa?

Chochitika choopsa kwambiri ndi phokoso lalikulu lokhazikika lochokera ku lamba wa mayunitsi a injini, mosasamala kanthu za liwiro. Kugwedezeka kosalekeza kumasonyeza kutsetsereka kwa lamba kosalekeza, ndipo kukangana kumeneku kumabweretsa kutentha kwakukulu, komwe kungayambitse moto m'chipinda cha injini. Chifukwa chake, muyenera kupita ku msonkhano posachedwa kuti muwone chomwe chimayambitsa phokoso la lamba wowonjezera.

Chifukwa chiyani (nthawi zonse) imayenda?

Phokoso losalekeza losasangalatsa limatha kuchitika pazifukwa zosiyanasiyana. Nthawi zina amayamba chifukwa cha miyala yaing'ono yomwe imamatira m'mizere ya lamba wowonjezera (pakali pano malamba okhala ndi nthiti amagwiritsidwa ntchito). Kuwonjezera pa kugwedezeka komwe kumayambitsa, ma pulley amawonongeka, zomwe zimalepheretsa mikanda ya lamba kuti isagwirizane nawo bwino: lamba nthawi zonse amatsutsana ndi ma pulleys. Phokoso losasangalatsa limathanso kulumikizidwa ndi kutembenuka kwathunthu kapena mwachangu kwa chiwongolero. Chifukwa cha izi nthawi zambiri chimakhala kumbali ya pulley yowongoleredwa yamagetsi. Kutsetsereka kumatha kuchitikanso pa alternator pulley - m'magalimoto okhala ndi electro-hydraulic kapena chiwongolero chamagetsi, kutayika kwa chiwongolero kudzakhalanso chizindikiro cha skid iyi. Chifukwa cha creaking lamba nthawi zambiri ndi tensioner kapena tensioner, ndipo pa nkhani ya magalimoto okonzeka ndi mpweya, kupanikizana wa kompresa ake.
