Mawuluka awiriawiri
Injini yoyatsira mkati ndi yabwino kwambiri, ndipo kuyiphatikiza ndi bokosi la gear ndi clutch kumabweretsa mavuto ena omwe opanga akhala akuyesera kuthetsa kwa zaka zambiri. Ndipo ziyenera kuvomerezedwa kuti akuchita bwino kwambiri.
Kusintha kwa mathamangitsidwe a pistoni, chifukwa cha kuwonjezera kapena kuvomereza gasi ndi dalaivala, ndi moto woipa wokha, komanso kusintha kwa kayendedwe ka pistoni, kumayambitsa kusintha kwa injini. . Izi zimapangitsanso kugwedezeka komwe kumachokera ku crankshaft kudzera pa flywheel, clutch ndi shaft kupita ku gearbox. Kumeneko amathandizira ku mano a gear. Phokoso lomwe limatsagana ndi izi limadziwika kuti phokoso lozungulira. Kugwedezeka kwa injini kumapangitsanso kugwedezeka kwa thupi. Zonse pamodzi zimachepetsa chitonthozo chaulendo.
Chodabwitsa cha kufalikira kwa ma vibrate kuchokera ku crankshaft kupita kuzinthu zotsatizana zadongosolo lagalimoto ndizowoneka bwino. Izi zikutanthauza kuti mphamvu ya ma oscillation awa imapezeka mumtundu wina wa liwiro lozungulira. Zonse zimatengera unyinji wozungulira wa injini ndi gearbox, kapena m'malo mwake pa nthawi ya inertia. Mphindi yayikulu ya inertia ya misa yozungulira ya gearbox, kutsika kwa liwiro lomwe chodabwitsa cha resonance chimachitika. Tsoka ilo, mu njira yachikale yopatsirana, gawo lalikulu kwambiri la unyinji wozungulira lili kumbali ya injini.
Silencer mu chishango
Ngakhale pali zovuta zotere, opanga adapeza kale njira yopewera kufalikira kwaulere kwa kugwedezeka kwa injini kupita kumayendedwe. Kuti muchite izi, chimbale cha clutch chimakhala ndi chotsitsa chotsitsa cha torsional. Amakhala ndi torsion ndi zinthu zokangana. Zoyambazo zikuphatikiza disk disk ndi counter disk, komanso akasupe a helical omwe ali muzodulidwa zofananira mu disk body. Mwa kusintha kukula kwa cutouts ndi akasupe, zosiyanasiyana kugwedera damping makhalidwe chingapezeke. Cholinga cha zinthu zogundana ndikuletsa kugwedezeka kwakukulu kwa damper ya vibration. Mkangano wofunikira wa kukangana pakati pa malo ogwira ntchito umatheka pogwiritsa ntchito mphete zowonongeka zopangidwa, mwachitsanzo, kuchokera ku pulasitiki yoyenera.
The vibration damper mu clutch disc yakhala ikusintha mosiyanasiyana pazaka zambiri. Pakali pano, kuphatikizapo. damper yokhala ndi magawo awiri yokhala ndi pre-damper yosiyana ndi magawo awiri ogwedera otsekemera okhala ndi pre-damper yophatikizika komanso kukangana kosiyanasiyana.
Kugwedera kugwetsa pa clutch disc sikugwira ntchito mokwanira. Resonance ndi phokoso lotsagana nalo limachitika pa liwiro lopanda ntchito kapena kupitilira apo. Kuti muchotse, muyenera kuonjezeranso nthawi ya inertia ya magawo osuntha a gearbox mothandizidwa ndi flywheel yowonjezera yomwe imayikidwa pazitsulo za gear. Komabe, njira yotereyi ingayambitse mavuto aakulu osuntha monga kugwirizanitsa kumafunika chifukwa cha kuchuluka kozungulira kwa gudumu lalitali la inertia.
Mawuluka awiriawiri
Yankho labwino kwambiri lingakhale kugawa unyinji wa flywheel m'magawo awiri. Imodzi imalumikizidwa mwamphamvu ndi crankshaft, ina imalumikizidwa ndi magawo ozungulira a gearbox kudzera pa clutch disc. Choncho, wapawiri misa flywheel analengedwa, zikomo kuti, popanda kuonjezera misa okwana flywheel, mbali imodzi, kuwonjezeka mu mphindi ya inertia wa misa mozungulira kufala anapindula, ndi mbali inayo. , kuchepa kwa mphindi ya inertia ya magawo ozungulira a injini. Chotsatira chake, izi zinapangitsa pafupifupi mphindi zofanana za inertia kumbali zonse ziwiri. Malo a damper kugwedezeka adasinthidwanso, omwe adasunthidwa kuchokera ku clutch disc pakati pa mbali za flywheel. Izi zimathandiza kuti damper igwire ntchito yowongolera mpaka madigiri 60 (pa clutch disc ili pansi pa madigiri 20).
Kugwiritsa ntchito ma flywheel amtundu wapawiri kunapangitsa kuti zitheke kusuntha ma oscillation amtundu wa resonant pansi pa liwiro lachabechabe, motero kupitilira kuchuluka kwa injini. Kuphatikiza pakuchotsa kugwedezeka kwamphamvu komanso phokoso lotsatsira, mawilo amtundu wapawiri amathandizanso kusuntha ndikuwonjezera moyo wa ma synchronizer. Zimalolanso ochepa peresenti (pafupifupi 5) kuchepetsa kugwiritsira ntchito mafuta.
Kwa makalasi achichepere
Kuyika mopingasa kwa injini ndi malo ochepa m'chipinda cha injini kumapangitsa kugwiritsa ntchito mawilo owuluka amitundu iwiri m'malo mwachikhalidwe kukhala kovuta kapena kosatheka. DFC (Damped Flywheel Clutch), yopangidwa ndi LuK, imakupatsani mwayi wogwiritsa ntchito maubwino amitundu iwiri yowuluka pamagalimoto ang'onoang'ono ndi apakatikati. Kuphatikiza kwa flywheel, mbale yokakamiza ndi clutch disc mugawo limodzi kumapangitsa kuti DFC ikhale yotakata ngati clutch yapamwamba. Kuphatikiza apo, msonkhano wa clutch wa DFC sufuna kuti clutch disc ikhale pakati.
Zofunikira, kulimba ndi mtengo
Flywheel yapadera yapawiri-mass imapangidwira injini yeniyeni ndi gearbox. Pachifukwa ichi, sichingayikidwe pamtundu wina uliwonse wagalimoto. Izi zikachitika, phokoso la kufalitsa sikungowonjezereka, koma flywheel yokha ikhoza kuwonongedwa. Opanga amaletsanso kusanja ma wheel-mass flywheel kukhala magawo. Chithandizo chilichonse chokonzekera malo opaka, "kusintha" kulikonse kwa gudumu ndikosavomerezeka.
Zikafika pakukhazikika kwa ma flywheel awiri, ndi bizinesi yachinyengo, momwe zimakhalira zimatengera zinthu zambiri, kuphatikiza momwe injiniyo ilili, kalembedwe kagalimoto ndi mtundu wake. Komabe, pali malingaliro oti iyenera kukhala nthawi yayitali ngati clutch disc. Palinso malingaliro aukadaulo omwe, pamodzi ndi zida zowakira, ma flywheel awiri-mass ayenera kusinthidwanso. Izi, ndithudi, zimawonjezera mtengo wosinthira, chifukwa gudumu lawiri-misa silotsika mtengo. Mwachitsanzo, mu BMW E90 320d (163 km) mtengo wa gudumu lopangidwa mochuluka ndi PLN 3738, pomwe m'malo mwake amawononga PLN 1423.
