Kodi ntchito ya flywheel ya galimoto ndi yotani?
Gawo looneka ngati diski lokhala ndi inertia yozungulira kwambiri limagwira ntchito ngati chipangizo chosungira mphamvu. Pa injini ya ma stroke anayi, ma stroke anayi aliwonse a pistoni amapanga mphamvu, zomwe zikutanthauza kuti ma stroke amphamvu okha ndi omwe amachita ntchitoyo, pomwe ma stroke otulutsa utsi, intake, ndi compression onse amagwiritsa ntchito mphamvu. Kumapeto kwa crankshaft, ndiko kuti, mbali yolumikizidwa ndi transmission ndi zida zogwirira ntchito. Ntchito yayikulu ya flywheel ndikusunga mphamvu ndi inertia kunja kwa ma stroke amphamvu a injini. Pa injini ya ma stroke anayi, stroke yamagetsi yokha ndi yomwe imatenga mphamvu kuchokera ku mphamvu yosungidwa ya flywheel.
Chiwongolero cha injini chili ndi mphamvu yozungulira kwambiri. Chifukwa cha mphamvu yopangira silinda iliyonse mu injini, liwiro la injini limasinthasinthanso. Liwiro la injini likakwera, mphamvu ya kinetic ya chiwongolero cha injini imawonjezeka ndipo mphamvu imasungidwa; liwiro la injini likachepa, mphamvu ya kinetic ya chiwongolero cha injini imachepa ndipo mphamvu imatulutsidwa. Ntchito yaikulu ya chiwongolero cha injini ndikuchepetsa kusinthasintha kwa liwiro panthawi yogwira ntchito ya injini.
Yoyikidwa kumbuyo kwa crankshaft ya injini, yokhala ndi rotational inertia, ntchito yake ndikusunga mphamvu ya injini, kuthana ndi kukana kwa zigawo zina, ndikupangitsa crankshaft kuzungulira mofanana; kudzera mu clutch yomwe imayikidwa pa flywheel, injiniyo imalumikizidwa ku transmission ya galimoto; imagwira ntchito ndi choyambira kuti injini iyambe bwino. Ndipo ndi malo olumikizirana a crankshaft position sensor ndi speed sensor.
Pa nthawi ya mphamvu yogwira ntchito, mphamvu yomwe injini imatumiza ku crankshaft, kupatula kutulutsa kunja, ilinso ndi gawo lomwe limatengedwa ndi flywheel, kotero kuti liwiro lozungulira la crankshaft silikuwonjezeka kwambiri. Mu utsi, intake, ndi compression strokes, flywheel imatulutsa mphamvu yake yosungidwa kuti igwirizane ndi ntchito yomwe imagwiritsidwa ntchito ndi strokes zitatuzi, kuti liwiro lozungulira la crankshaft lisachepe kwambiri.
Kuphatikiza apo, flywheel ili ndi ntchito zotsatirazi: Flywheel ndi gawo logwira ntchito la clutch yokangana; m'mphepete mwa flywheel, pali giya lozungulira flywheel loyatsira injini; pa flywheel, palinso chizindikiro chapamwamba choyimitsa nthawi yoyatsira kapena nthawi yopangira mafuta, komanso kusintha malo otseguka a valavu.
Zizindikiro zazikulu za flywheel yowonongeka m'galimoto ndi kugwedezeka kwa injini, phokoso losazolowereka, kuvutika kuyambika, kusalinganika kwa magiya, kuvutika kusuntha magiya, kutsetsereka kwa clutch kapena kusagwira bwino ntchito, komanso phokoso losazolowereka kapena kugwedezeka kwa clutch.
Kuvuta kuyamba ndi kulephera kuchita zinthu molakwika:
Phokoso losazolowereka komanso phokoso la kukangana kwa zitsulo panthawi yoyatsira, kapena phokoso lalikulu la chitsulo, komanso kuyesa kangapo kuyambitsa kumalephera. Izi nthawi zambiri zimachitika chifukwa cha kuwonongeka kapena kusinthika kwa giya la mphete ya flywheel, zomwe zimapangitsa kuti giya yaying'ono yoyambira isathe kulumikiza bwino; pamene kuwonongeka kwa giya la mphete kupitirira mano anayi, gudumu la flywheel liyenera kusinthidwa.
Kugwedezeka panthawi yogwira ntchito: Kugwedezeka kosalekeza mu chiwongolero kapena thupi la galimoto panthawi yogwira ntchito, ndipo kugwedezeka kumachepa pamene clutch yatsika. Ichi ndi chikhalidwe cha flywheel dynamic balance yolephera, yomwe imasokoneza kuzungulira bwino kwa crankshaft ndikupangitsa kuti galimoto imveke bwino.
Kutumiza mphamvu molakwika: Pakuthamanga, liwiro la injini limawonjezeka koma liwiro la galimoto limakwera pang'onopang'ono, kumva ngati "kugwedezeka koma osasuntha", ndipo kugwiritsa ntchito mafuta kungawonjezere ndi 10%-30%. Kugwedezeka kwa kusweka kwa spring ya flywheel's double mass shock absorber spring kapena kusalinganika kwa flywheel transmission kungayambitse kusungidwa ndi kutulutsidwa kwa mphamvu kosakhazikika, zomwe zimapangitsa kuti mphamvu ichedwe.
Kuchepa kwakukulu kwa magwiridwe antchito: Liwiro lalikulu kwambiri lingachepe ndi 15-20 km/h, kuthekera kokwera kungathe kuchepa ndi 40%, ndipo pakhoza kukhala phokoso losazolowereka mu shaft yotumizira. Kunyalanyaza kwa nthawi yayitali kungayambitse kuwonongeka kwina monga kuwonongeka kwa shaft yolowera ya shaft.
Zolakwika zachilendo za clutch ndi transmission system:
Kugwira ntchito kwachilendo kwa clutch:
Kutsetsereka kwa clutch: Kuvuta kuyambira ndi liwiro lotsika, kuthamanga pang'ono, komanso milandu yoopsa kumatha kutulutsa fungo lopsa kapena utsi.
Kuchotsa clutch kwathunthu: Clutch pedal singathe kuchepetsedwa mokwanira kuti idule mphamvu, zomwe zimapangitsa kuti zikhale zovuta kusuntha magiya, mano agwe, kapena kulephera kuyimitsa galimoto.
Phokoso ndi kugwedezeka: Kugwedezeka kumatuluka mu mkhalidwe wovuta, ndipo poyambira kapena kuleka kugwira ntchito, pamakhalanso kugwedezeka. Zizindikirozi nthawi zambiri zimachitika chifukwa cha kuthamanga kwambiri kwa flywheel (> 0.2mm) kapena kuwonongeka kwa contact plane, zomwe zimakhudza magwiridwe antchito abwinobwino a clutch. Kusokonezeka kwa makina otumizira: Pakusintha giya, pamakhala kumverera kokakamira, kuvutika kusuntha giya, kapena kusalingana kwa gearbox. Kuwonongeka kwa flywheel kudzasokoneza mwachindunji kulumikizana pakati pa clutch ndi gearbox, zomwe zimapangitsa kuti magiya asagwire bwino ntchito.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
