Thaum xaiv lub tsheb kauj vab me me rau cov menyuam hnub nyoog 2-12, cov khoom siv ncej ncaj qha txiav txim siab qhov hnyav, tuav nyuaj thiab kev nyab xeeb caij. Tam sim no, tsuas muaj peb yam khoom tseem ceeb ntawm kev ua lag luam: magnesium alloy integrated casting, 6061 aluminium alloy, thiab high-carbon steel vuam. Qhov sib txawv tseem ceeb yog nyob rau hauv qhov ntom, txheej txheem, qhov hnyav, durability thiab muaj hnub nyoog. Cov hauv qab no yuav qhia meej cov kev sib txawv no nrog cov kev txheeb xyuas tau. Cov niam txiv yuav tsum xaiv raws li lawv tus menyuam qhov hnyav thiab caij tsheb yam tsis tau them nyiaj rau kev txawj ntse.
1. Magnesium alloy integrated casting: Ultra-lub teeb flagship, thawj qhov kev xaiv rau cov menyuam hnub nyoog 2-5 xyoos
Magnesium alloy yog cov khoom siv uas muaj qhov ntom ntom qis tshaj plaws ntawm cov paub ntau yam - cov hlau tsim, kwv yees li 1.74g / cm³, txog 1/3 sib zog dua aluminium. Lub F805 Me Aurora ntawm Montasen tau txais kev dav hlau - qib magnesium alloy integrated casting thav duab, nrog rau txhua tus ncej hnyav txog 680g thiab tag nrho qhov hnyav ntawm lub tsheb kauj vab yog kwv yees li 3.1kg. Qhov hnyav no sib npaug li cas? Nws yog kwv yees li ntawm ob lub 1.5L ntxhia dej fwj, thiab ib tug poj niam niam txiv tuaj yeem nqa nws mus rau tsib plag tsev nrog ib txhais tes.
Nyob rau hauv cov nqe lus ntawm cov txheej txheem, integrated casting tsis muaj vuam seams, thiab lub zog yog faib tusyees. Nws tau dhau los ntawm JIS 700,000 vibration test. Lub thav duab sab hauv yog hollow los txo qhov hnyav, thiab sab nrauv yog du yam tsis muaj cov ntsiab lus vuam. Thaum tus me nyuam ntog ntawm lub tsheb kauj vab, lawv yuav tsis raug khawb los ntawm cov caws pliav. Txawm li cas los xij, qhov tsis zoo yog tias tus nqi siab, thiab kev nqis peev hauv cov pwm casting yog qhov loj, yog li muaj ob peb lub npe uas tiag tiag tsim magnesium alloy integrated me nyuam tsheb kauj vab ntawm kev ua lag luam.
Cov xwm txheej siv tau: Rau cov menyuam yaus hnub nyoog 2-5 xyoo nyob rau hauv lub caij tsheb kauj vab sib npaug, nrog lub zog me me thiab nquag thauj niam txiv. Hom qauv: F805 Me Aurora (magnesium alloy integrated casting, ob lub log pedal, tag nrho qhov hnyav 3.1kg).
2. 6061 aluminium alloy: Lub teeb yuag thiab ruaj khov, qhov kev xaiv tseem ceeb rau cov menyuam hnub nyoog 6-12 xyoos
6061 aluminium alloy yog cov khoom siv yooj yim tshaj plaws hauv kev lag luam tsheb kauj vab me nyuam, nrog qhov ceev ntawm kwv yees li 2.7g / cm³, thiab tom qab T6 kev kho cua sov, lub zog tawm los tuaj yeem ncav cuag tshaj 240MPa. Cov qauv xws li F08 Flyer, EB01 Stretch Rider, AB03 / AB06 thiab lwm yam. tag nrho siv 6061 aluminium alloy thav duab, nrog rau tag nrho qhov hnyav tswj ntawm 7.5-13kg.
Raws li cov txheej txheem, aluminium alloy thav duab siv hydraulic kos duab thiab vuam, thiab lub raj zoo tuaj yeem ua kom nyias thiab sib zog dua siab - carbon steel, nrog qhov hnyav ntawm li 40% piv rau siab - carbon steel. Qhov saum npoo yog kho nrog anodizing lossis pleev xim, uas muaj kev tiv thaiv corrosion zoo, thiab nws tuaj yeem so qhuav tom qab ntub dej nag, thiab nws tsis tuaj yeem xeb. Tus nqi saib xyuas yog tsawg, thiab khawb tuaj yeem kho nrog cov xim.
Cov xwm txheej siv tau: Rau cov menyuam yaus hnub nyoog 6-12 xyoo nyob rau hauv lub caij tsheb kauj vab pedal, tus menyuam tuaj yeem caij tsheb los ntawm lawv tus kheej, thiab kev xav tau kev thauj mus los ntawm niam txiv txo qis, tab sis lub tsheb yuav tsum tau ua kom ntev. Hom qauv: F08 16-inch (txhuas 6061, tag nrho qhov hnyav txog 7.5kg), EB01 14-16-inch ncua qauv (txhuas, yim txoj kev hloov kho).
3. High- carbon steel vuam: pheej yig tab sis hnyav, xaiv nrog ceev faj
Siab- carbon steel muaj qhov ceev ntawm kwv yees li 7.85g / cm³, hnyav tshaj plaws ntawm peb cov khoom. Piv rau aluminium alloy ntawm tib qhov loj, nws yog li 60% -80% hnyav dua. Qee tus nqi qis- cov menyuam yaus tsheb kauj vab luv luv ntawm kev ua lag luam (xws li qee yam Phoenix thiab Perpetual nkag- qauv qauv) siv cov pa roj carbon steel thav duab, nrog lub tsheb kauj vab 16-nti ncav cuag 11-13kg, ze rau 50% ntawm tus menyuam qhov hnyav.
Nyob rau hauv cov nqe lus ntawm cov txheej txheem, lub siab - carbon steel thav duab yog ib tug welded qauv, thiab cov ntsiab lus weld yog nquag xeb, thiab lawv yuav corrode thiab perforate nyob rau hauv ib tug ntev - lub sij hawm ntub ib puag ncig. Qhov kom zoo dua yog tias tus nqi qis, thiab nws muaj kev poob siab zoo (cov ncej steel muaj elasticity), tab sis qhov hnyav hnyav dhau - tus menyuam caij tsis tau, niam txiv tsis tuaj yeem nqa nws, thiab thaum muaj xwm txheej ceev, tus menyuam tsis tuaj yeem tswj lub tsheb kauj vab.
Kev xa tawm tswv yim: Tshwj tsis yog tias cov peev nyiaj tsawg kawg nkaus thiab kev caij tsheb luv luv (50 metres hauv thaj chaw nyob), nws tsis pom zoo kom xaiv siab - carbon steel menyuam tsheb kauj vab. Yog tias koj twb tau yuav ib qho lawm, ua tib zoo saib xyuas seb cov ntsiab lus vuam puas xeb thiab yog tias cov ntsia hlau xoob.
Plaub qhov tseem ceeb ntawm peb cov khoom sib piv
Los ntawm qhov ntom ntom, magnesium alloy yog kwv yees li 1.74, aluminium alloy yog kwv yees li 2.7, thiab siab - carbon steel yog kwv yees li 7.85.
Los ntawm qhov hnyav ntawm 16-inch tag nrho lub tsheb kauj vab ntawm tib qhov loj, magnesium alloy tshuav nyiaj li cas tsheb kauj vab yog kwv yees li 3.1kg, aluminium pedal tsheb tuam yog kwv yees li 7.5kg, thiab cov tsheb kauj vab siab carbon steel pedal yog kwv yees li 11-13kg.
Los ntawm txoj kev xav ntawm kev tsim khoom, magnesium alloy yog ua tiav los ntawm kev sib xyaw tuag-casting yam tsis muaj cov ntsiab lus soldering, aluminium alloy yog welded los ntawm hydraulic tube extraction, thiab siab - carbon steel yog welded los ntawm steel hlab.
Nyob rau hauv cov nqe lus ntawm corrosion kuj, magnesium alloy yuav tsum tau kho deg los tiv thaiv oxidation. Aluminium alloy yog ib txwm resistant rau corrosion. High- carbon steel yog qhov yooj yim rau xeb thiab yuav tsum tau saib xyuas.
Los ntawm qhov kev xav ntawm tus nqi ntau, magnesium alloy yog qhov kim tshaj plaws, aluminium alloy yog nruab nrab - nqi, thiab siab - carbon steel yog qis tshaj - nqi.
V. Yuav Ua Li Cas Xaiv Cov Khoom Siv Rau Cov Menyuam Nruab Nrab thiab Loj - lub tsheb kauj vab loj
2-4 xyoos tshuav nyiaj li cas tsheb kauj vab theem: Thawj qhov kev xaiv yog magnesium alloy integrated tuag-casting. Thaum lub hnub nyoog no, cov menyuam yaus muaj cov leeg tsis muaj zog, thiab qhov hnyav ntawm tag nrho lub tsheb yuav tsum zoo dua tsis pub tshaj 30% ntawm lawv lub cev hnyav. Ib lub tsheb kauj vab 3.1kg magnesium alloy tshuav nyiaj li cas yog txoj cai rau tus menyuam 12kg.
5-8 xyoo kev hloov pauv theem: xaiv aluminium alloy. Cov menyuam yaus pib caij tsheb kauj vab nrog cov pedals, thiab yuav tsum muaj lub thav duab ruaj khov dua los tiv thaiv kev cuam tshuam. Aluminium alloy muaj qhov hnyav tsim nyog thiab yooj yim los tswj.
9-14 xyoo roob/off-road theem: Xaiv aluminium alloy kis las geometry ncej. Piv txwv li, lub Montasen AB06 24-inch, aluminium alloy ncej yog nruab nrog cov hloov pauv thiab cov nres nres, thiab tag nrho lub tsheb hnyav txog 12-13kg, ua tiav qhov sib npaug ntawm lub teeb thiab rigidity.
VI. Zam kev poob siab hauv kev yuav khoom
Qhov 1: cim tias yog "magnesium alloy" tab sis qhov tseeb nws yog magnesium-aluminium alloy plhaub nrog npuas txheej. Qhov tseeb magnesium alloy integrated tuag-casting thav duab muaj ib tug tiag tiag phab ntsa thickness, thiab lub khob suab yog meej, nrog ib tug luj ntawm tsawg tshaj li 3.5kg. Yog tias tag nrho lub tsheb hnyav dua 5kg thiab tseem raug cim tias yog magnesium alloy, nws yog qhov kev tshaj tawm cuav.
Qhov 2: Tsuas yog saib cov khoom thav duab yam tsis xav txog qhov hnyav ntawm tag nrho lub tsheb. Qee lub thav duab yog ua los ntawm aluminium alloy, tab sis lub hauv ntej diav rawg yog siab - carbon steel, thiab lub log yog hlau. Tag nrho lub tsheb tseem hnyav dua 12kg. Ua ntej yuav, nug kom meej txog "tag nrho qhov hnyav" es tsis txhob "cov khoom siv".
Qhov 3: Tsis quav ntsej txog kev thauj mus los. Yog tias koj yuav tsum nqa nws saum toj lossis muab tso rau hauv lub cev txhua hnub, qhov hnyav yog qhov tseem ceeb tshaj li cov khoom siv. Yog hais tias ib tug ntxhais niam txiv tsis tuaj yeem nqa lub tsheb kauj vab nrog ib txhais tes, tus me nyuam lub caij tsheb kauj vab yuav poob qis heev.
