Kodi chiwongolero cha galimoto ndi chiyani?
Chingwe chowulukira (gudumu louluka) ndi gawo looneka ngati diski lomwe lili ndi inertia yozungulira kwambiri. Ntchito yake ndi yofanana ndi 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 amagwira ntchito, pomwe ma stroke otulutsa mpweya, intake, ndi compression onse amagwiritsa ntchito mphamvu. Chifukwa chake, mphamvu yotulutsa crankshaft imasinthasintha nthawi ndi nthawi, ndipo liwiro la crankshaft silikhazikika. Kuti zinthu ziyende bwino, flywheel imayikidwa kumapeto kwa crankshaft.
Pamapeto pa mphamvu yotulutsa ya crankshaft, ndiko kuti, mbali yolumikizidwa ku giya ndi zida zogwirira ntchito. Ntchito yayikulu ya flywheel ndikusunga mphamvu ndi kusakhala ndi mphamvu kunja kwa power stroke ya injini. Pa injini ya stroke zinayi, power stroke 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 ndikusunga mphamvu; liwiro la injini likachepa, mphamvu ya kinetic ya chiwongolero cha injini imachepa ndikutulutsa mphamvu. Chiwongolero cha injini chingagwiritsidwe ntchito kuchepetsa kusinthasintha kwa liwiro panthawi yogwira ntchito ya injini.
Choyikidwa kumbuyo kwa crankshaft ya injini, ndi inertia yozungulira, ntchito yake ndikusunga mphamvu ya injini, kuthana ndi kukana kwa zigawo zina, ndikupangitsa crankshaft kuzungulira mofanana; kudzera mu clutch yomwe ili pa flywheel, kulumikiza injini ndi transmission ya galimoto; kugwira 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 la mphamvu yomwe imatengedwa ndi flywheel, kotero kuti liwiro la crankshaft silikuwonjezeka kwambiri. Mu utsi, intake, ndi compression strokes, flywheel imatulutsa mphamvu yosungidwa kuti igwirizane ndi ntchito yomwe imagwiritsidwa ntchito ndi strokes zitatuzi, kuti liwiro 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.
Vuto lalikulu la kuwonongeka kwa mawilo a galimoto limaonekera ngati kugwedezeka kwa injini ndi phokoso losazolowereka, kuvutika kuyambika, kusalingana kwa magiya oyendera galimoto akamasuntha, kuvutika kusuntha magiya, komanso kutsetsereka kwa clutch kapena kulephera kugwira ntchito bwino.
Kuyamba ndi ntchito yolakwika ya injini
Kuvuta poyambira ndi phokoso losazolowereka: Poyambira, pamakhala phokoso lachitsulo kapena phokoso la giya. Milandu yoopsa ingafunike kuyesera kangapo kuti muyambe. Izi nthawi zambiri zimachitika chifukwa cha kuwonongeka kwa giya la mphete ya flywheel, zomwe zimapangitsa kuti giya loyambira lilephereke kulumikiza bwino. Ngati kuwonongeka kwa giya la mphete kupitirira mano anayi, giya la flywheel nthawi zambiri limafunika kusinthidwa.
Kugwedezeka ndi phokoso losazolowereka panthawi yothamanga: Panthawi yogwira ntchito, chiwongolero ndi thupi la galimoto zimaonetsa kugwedezeka kosalekeza. Kugwedezekako kumachepa kwambiri pamene clutch pedal yatsika. Ichi ndi chizindikiro chachizolowezi cha kulephera kwa flywheel dynamic balance. Poyendetsa galimoto, pakhoza kukhala phokoso lachitsulo, ndipo phokoso losazolowereka limakula panthawi yothamanga mwadzidzidzi.
Kutumiza mphamvu ndi magwiridwe antchito akuchepa
Kuchedwa kwa liwiro ndi kusowa kwa mphamvu: Pakuthamanga, liwiro la injini limawonjezeka koma liwiro la galimoto silimawonjezeka mofulumira, kumva ngati "kugwedezeka koma osasuntha". Thupi la galimoto limagwedezeka kwambiri poyambira pang'onopang'ono. Izi zimachitika chifukwa cha kuwonongeka kwa pamwamba pa flywheel kapena kulephera kwa springi yonyowa, zomwe zimakhudza kugwira ntchito bwino kwa magetsi.
Kuwonjezeka kosazolowereka kwa kugwiritsa ntchito mafuta ndi kuchepa kwa magwiridwe antchito: Kugwiritsa ntchito mafuta kungawonjezeke ndi 10%-15%, liwiro lalikulu lingachepe ndi 15-20 km/h, ndipo kuthekera kokwera kungathe kuchepa ndi 40%. Magalimoto odziyendetsa okha amatha kuchedwa kusintha kapena kugwedezeka.
Zolakwika pa ntchito ya Clutch ndi transmission
Kutsetsereka kwa clutch: Mukayamba ndi giya lotsika, kumasula clutch pedal kumapangitsa kuti galimoto isayambe kapena kumakhala kovuta kuyambitsa; panthawi yothamanga, liwiro la galimoto silingakwere ndi liwiro la injini, kumva ngati silikugwira ntchito, ndipo pakakhala zovuta kwambiri, pakhoza kukhala fungo lopsa kapena utsi. Clutch yosatulutsidwa kwathunthu komanso phokoso losazolowereka: Clutch pedal ikachepetsedwa kwathunthu, mphamvu singathe kudulidwa kwathunthu, zomwe zimapangitsa kuti magiya azisinthasintha, phokoso lotuluka kapena kulephera kuyima; pedal ikachepetsedwa pang'ono, phokoso lopitirira "lodina" lingamveke.
Kusalinganika kwa ma transmission: kumawonekera ngati kusinthana kwa ma gear, kuvutika kusuntha ma gear kapena phokoso losazolowereka panthawi yogwirana. Kuthamanga kwa flywheel yopitilira 0.2mm kudzapangitsa kuti clutch isatuluke kwathunthu, zomwe zingakhudze momwe ma transmission amagwirira ntchito.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
