Yuav ua li cas paub qhov txawv Freewheel thiab Cassette

Qhov sib txawv ntawm cassette flywheel thiab rotary flywheel yog: txawv disassembly, txawv qauv thiab sib txawv siv tsheb.

1, Kev sib txuas ntawm flywheel thiab hub ntawm cassette flywheel yog spline ntauwd puag thiab xauv daim, thiab cov hniav tuaj yeem raug tshem tawm. Cov hniav discs ntawm cassette flywheel yog daig ua ke ib tug los ntawm ib tug, thiab muaj ib tug pej thuam puag nyob rau hauv nruab nrab, yog li ntawd koj muaj peev xwm teem lawv ib tug los ntawm ib tug. 9 ceev yog tsim los ntawm 9 flywheels, yog tias muaj ib lub flywheel cais tsis zoo, nws tuaj yeem hloov tau nyias.
2, Kev sib txuas ntawm flywheel thiab hub ntawm spin flywheel yog threaded, thiab cov hniav tsis tuaj yeem disassembled. Spin flywheel yog ib qho, yog tias muaj cov hniav tsis zoo los hloov tag nrho.

1, Lub ratchet qauv ntawm spin flywheel yog nyob rau hauv lub flywheel, tsis nyob rau hauv lub hub, uas yog tib yam qauv ntawm tsoos tsheb kauj vab ib tug ceev flywheel.
2, Lub ratchet qauv ntawm cassette flywheel yog nyob rau hauv lub pej thuam puag ntawm lub hub, thiab lub flywheel tsuas yog tsim los ntawm ob peb cov hniav, tsis muaj kev nyuaj sab hauv.

1, Spin flywheel feem ntau yog siv rau hauv ib lub tsheb kauj vab nrawm, nce tsheb kauj vab, cov tsheb kauj vab hloov pauv qub thiab cov tsheb kauj vab qis kawg, xws li 6 ceev thiab 7 ceev tsheb kauj vab.
2, Lub cassette flywheel ruaj khov dua, sib dua thiab tuaj yeem ua rau cov hniav me me, yog li cov tsheb kauj vab niaj hnub hauv nruab nrab thiab qib high-end feem ntau siv cassette flywheel.

Nws yog li ntawd lub npe vim hais tias nws yog mounted ncaj qha rau ntawm tus pej thuam puag ntawm lub rear hub (ie rear qag) thiab yog nias nrog ib tug threaded flywheel sab saum toj cover. Lub ratchet qauv ntawm lub cassette flywheel (uas yog, lub hauv paus ntawm "nias" suab thaum lub rear log yog idling tsis muaj pedaling) nyob rau hauv lub hub lub pej thuam puag, thiab lub flywheel yog tsim los ntawm ob peb cov hniav, tsis muaj teeb meem. sab hauv qauv.
Muaj ob hom cassette flywheel mounts: Japanese (Shimano specification) thiab Italian (Campagnolo specification), uas Japanese yog feem ntau thiab Italian yog ntau tshaj ntawm txoj kev tsheb kauj vab nrog Campagnolo kis tau tus mob / hloov khoom siv.

Lub flywheel yog screwed ncaj qha mus rau cov xov ntawm spinning hub los ntawm cov xov uas tuaj nrog flywheel. Lub ratchet qauv ntawm ib tug spin flywheel yog nyob rau hauv lub flywheel, tsis nyob rau hauv lub hub, raws li yog cov ntaub ntawv nrog ib tug ceev flywheel ntawm ib txwm tsheb tuam.
Vim tias lawv cov kev tsim kho ruaj khov dua, lub cev nyhav dua, thiab muaj peev xwm ua kom cov hniav me me, cov tsheb kauj vab niaj hnub hauv nruab nrab mus rau qib siab feem ntau yuav siv cov cassette flywheels, thaum spin flywheels muaj nyob rau ntawm ib-ceev tsheb kauj vab, climbers ( nrog rau lub flywheel rau pem hauv ntej ntawm cov hniav), cov laus hloov tsheb kauj vab, thiab qis-kawg nkag-qib kev ua si nawv tsheb kauj vab. Tam sim no, spin flywheels muaj txog li 10 tus hniav, piv txwv li 10 speeds, thaum cassette flywheels muaj nyob rau hauv 12 speeds.
