Ib pawg uas siv tsis muaj saw thiab tsis muaj mechs tab sis lub driveshaft hloov: Puas yog lub neej tom ntej?
Txog tam sim no ntawm Eurobike, ib yam khoom tau hais txog ntau dua li lwm yam: CeramicSpeed DriveEn lub tswv yim groupet.
Txhim kho nrog University of Colorado, lub kaw lus siv cov pa roj carbon fiber ntau tsav hauv qhov chaw ntawm cov saw hlau ib txwm ua, ua kom deb ntawm qhov xav tau rau lub tsheb derailleur hauv cov txheej txheem.
Ceramic Ceev thov cov txheej txheem ua haujlwm tau zoo dua li txawm tias qhov ua tau zoo tshaj plaws derailleur-based drivetrains ntawm lub khw.
Nws tseem qhia tau tias nws siv tau ntev dua vim tias nws tshem tawm qhov hnav nrog cov saw thiab ob lub hauv ntej thiab nram qab mech.
Lub 21-cov kabmob cov menyuam pinion tsav ncej pom ob lub kabmob pinions ntawm qhov kawg ntawm tus tsav ncej muab lub zog hloov pauv, tshem tawm yim lub ntsiab lus ntawm cov saw zawv zawg kev sib txhuam thiab tshem tawm qhov kev pheej hmoo ntawm kev sib tsoo.
Cov bearings txuas nrog cov hniav ntawm 13-ceev cassette thiab chainring ntawm lub kaum sab xis los txhawb lub tsheb kauj vab. Txhawm rau hloov cov iav, cov bearings nram qab txav mus rau hauv cov ncej uas tau cog lus zoo thiab nthuav mus rau qhov sib txawv cogs.
CeramicSpeed tus thawj coj thev naus laus zis Jason Smith tau tshaj tawm qhov kev nce qib no hauv cov cuab yeej siv hauv pawg thiab tau hais tias nws yog qhov tshwm sim ntawm lub hom kev tsav tsheb mus tas li kom ua tau zoo dua caij tsheb.
'CeramicSpeed tau txaus siab ua tiav qhov ntau tau hais tias ua tsis tau. Peb tau ua tiav 99% kev tsav tsheb ntau lub nrawm thaum tshem tawm cov saw hlau thiab cov tsheb sib tsoo nyuaj, 'Smith
'Kev nce qib hauv kev siv tshuab tsav tsheb tau hloov pauv txij li xyoo 1920. DrivEn yog qhov hloov pauv tiag tiag muab nws qhov tshwj xeeb dov lub zog hloov pauv thiab kev ua haujlwm tsis sib xws.
Lub tswv yim DrivEn muaj peev xwm hloov txoj hauv kev lag luam kev caij tsheb kauj vab pom kev tsim qauv thiab tsav tsheb ua haujlwm tau zoo.'
Cov CeramicSpeed DriveEn pawg tau ntim nws tus kheej ib qho khoom plig ntawm Eurobike ua ib qho ntawm cov khoom lag luam tshiab tshaj plaws ntawm kev ua yeeb yam.
Tam sim no, txawm li cas los xij, tsis muaj kev npaj yuav coj cov txheej txheem rau cov neeg siv khoom lag luam.
