Lub flywheel, yam tsis muaj exaggeration, tuaj yeem hu ua ntau yam khoom siv. Nws tsis tsuas yog them nyiaj rau qhov tsis sib xws ntawm lub crankshaft thiab xa torque los ntawm lub cav mus rau lub gearbox, tab sis kuj tig lub crankshaft thaum pib txheej txheem. Torque pulsations yog smoothed tawm vim lub sij hawm luv luv tsub zuj zuj thiab tom qab tso tawm ntawm kinetic zog. Lub zog cia tshwm sim thaum lub sij hawm stroke ntawm lub piston, thiab kev noj tshwm sim nyob rau hauv lwm lub voj voog. Nyob rau tib lub sijhawm, lub tog raj kheej ntau dua (thiab, yog li ntawd, ntau dua tag nrho lub sijhawm stroke), qhov sib txawv ntawm lub cav no ntau dua, uas txhais tau hais tias qhov loj ntawm flywheel yuav tsawg dua.

Muaj ntau hom flywheels raws li lawv tsim. Feem ntau - khoom - yog ib tug loj cam khwb cia-hlau disc nrog ib txoj kab uas hla ntawm 30-40 mm nrog ib tug steel iav rim nias ntawm nws sab nrauv, uas xyuas kom meej tias lub crankshaft yog tig thaum pib nrog kev pab los ntawm ib tug oob khab. Kuj tseem muaj dual-mass flywheel thiab lub teeb yuag. Kev siv ntawm ob-mass flywheel, suav nrogob lub discs suav nrog, ua rau nws muaj peev xwm tshem tawm kev teeb tsa ntawm lub tshuab damping hauv clutch disc. Lub teeb yuag flywheel feem ntau yog siv thaum kho lub cav. Qhov txo qis hauv lub sijhawm ntawm inertia tshwm sim vim qhov kev hloov pauv ntawm qhov loj ntawm lub flywheel los ze zog mus rau cov npoo ntawm lub disk, vim nws qhov hnyav txo (txog 1.5 kg), cov yam ntxwv dynamic tau txhim kho, thiab lub cav. hwj chim kuj nce (txog 5%).

Dual-mass flywheel ua haujlwm li cas?

Lub flywheel no tsis muaj ib qho tab sis ob lub tsev. Thawj ntawm lawv txuas ncaj qha mus rau lub crankshaft thiab tseem yog lub crown ntawm lub oob khab. Qhov thib ob lub cev yog lub hauv paus rau mounting lub clutch los ua ke. Ob lub tsev nyob sib cuam tshuam los ntawm txoj kev ntawm cov kabmob dawb (radial thiab thrust), uas muaj qhov nruab nrab damping system. Cov cuab yeej sib txuas tso cai rau lawv txav mus rau cov txheeb ze ntawm ib leeg hauv cov kev taw qhia axial. Sab hauv ntawm ob-mass flywheel yog sau nrog roj kom ntseeg tau tias kev ua haujlwm zoo thiab raug ntawm cov pob khoom caij nplooj ntoos hlav. Cov pob khoom, dhau los, raug cais los ntawm cov yas cais tshwj xeeb uas tiv thaiv lawv los ntawm kev thaiv.

Lub dual-mass flywheel ua haujlwm ntawm lub hauv paus ntsiab lus. Qhov muag muag ntawm thawj theem yog lub luag haujlwm rau kev pib thiab kaw lub cav. Stiffer thib ob theem springs muab torsional damping thaum ib txwm tsav tsheb.

Qhov kev tsim no yog tsim kom muaj kev ntseeg tau ntau dua dampen kev co, txo suab nrov, txo kev hnav ntawm synchronizers, tiv thaiv lub cav kis tau tus moblos ntawm overloads, yooj yim ntawm iav hloov. Nyob rau tib lub sijhawm, nce kev hnav ntawm lub caij nplooj ntoos hlav-damper tshwm sim, feem ntau xaus rau hauv kev tawg ntawm lub caij nplooj ntoos hlav arc, lub ntsiab tseem ceeb ntawm ob pawg flywheel.

Thaum twg yuav tsum hloov lub tshuab hluav taws xob dual-mas?

Lub cav ua haujlwm tsis sib xws, kev vibration thiab suab nrov ntawm qhov tsis ua haujlwm tuaj yeem ua rau kev ua haujlwm tsis zoo ntawm lub tshuab hluav taws xob, lub plunger khub, lub tog raj kheej, nrog rau lwm yam khoom siv thiab cov khoom sib dhos, suav nrog cov cim qhia tias lub flywheel dual-mas yog faulty. Cov tsos mob uas qhia meej tias nws yog lub sijhawm los hloov nws yog raws li hauv qab no:

  • tsim cov kab nrib pleb ntawm qhov chaw;
  • poob ntawm cov roj nplua nyeem hauv clutch vaj tse;
  • tig tsis tau rau ob qho tib si.

Kho ntawm ob lub dav hlau flywheel nyob rau hauv cov khoom siv dag zog yuav luag tsis tuaj yeem, thiab yog li nws feem ntau hloov pauv tag nrho.

Txawm hais tias, qee zaum, kev kho dua tshiab thiab rov tsim lub flywheel tuaj yeem pheej yig dua li kev yuav ib lub tshiab (tus nqi tsawg kawg yog $ 500). Lwm qhov kev xaiv yuav yog los hloov nws nrog ib txwm-hlau ib txwm - ib qho analogue ntawm ob pawg.

Raws li cov kws tshaj lij, rau kev ua haujlwm ntev dua thiab txhim khu kev qha ntawm ob lub dav hlau flywheel, nws yog ib qho tsim nyog yuav tsum ua raws li cov cai ntawm kev ua haujlwm, xws li: rau cov cav tov diesel tsim los ua haujlwm nrog lub zog siab, tsis txhob cia ntev. kev ua haujlwm ntawm qhov ceev qis, thiab tseem ua rau lub clutch pedal ua ntej tua lub cav.
