Vim li cas Txuas Titanium Brake Rotors?
Qhov twg qhov hnyav txo, kev tiv thaiv corrosion thiab thermal stability yog qhov tseem ceeb hauv kev ua haujlwm thiab kev nyab xeeb hauv cov tshuab nres, titanium Rotor Bolts hloov steel fasteners. Qib 5 titanium (Ti-6Al-4V) yog sib npaug lossis zoo dua li Chav Kawm 10.9 steel hauv tensile lub zog tab sis yog 45% tsawg dua cov hlau alloy (7.85 g / cm3) siv rau rotor bolts.
Rau -bolt maus taus pem hauv ntej nres rotors -- titanium txuag 25-35 grammes tshaj hlau. Tej zaum nws yuav yog me ntsis, tab sis txhua gramme tawm ntawm lub rooj sib dhos lub log txo gyroscopic tsis kam thiab ua rau kev ncua kev ua raws. Rau pab pawg sib tw nws yog ntsuas nyob rau hauv feem ntawm lub sij hawm lap-time; rau cov neeg caij tsheb hauv txoj kev nws txhais tau hais tias kev tig nrawm dua thiab cov lus qhia meej pem hauv ntej-kawg nyob rau hauv lub zog braking.
Dhau li ntawm nws qhov hnyav, titanium muaj cov txheej txheem oxide passive (TiO2) uas loj hlob hauv huab cua thiab kho thaum khawb. Qhov no tiv thaiv galvanic corrosion thiab qaug dab pegsteel boltsthreaded rau hauv txhuas hubs, ib qho teeb meem rau maus taus caij rau ntawm ntug dej hiav txwv los yog salted caij ntuj no txoj kev.
Ti-6Al-4V: Qib 5 Standard rau Brake Hardware
Tsis yog txhua lub titanium yog haum rau nres rotor fastening. Kev lag luam ntshiab Qib 2 titanium (~ 345 MPa tensile) yog tsim nyog rautsis yog - cov khoom siv tshuaj pleev ib cetab sis yuav ncab thiab shear nyob rau hauv braking loads. Qib 5 Ti-6Al-4V - 90% titanium, 6% aluminium, 4% vanadium - yog tus qauv kev lag luam rau cov kabmob load-bearing brake fasteners.
Cov khoom tseem ceeb ntawm Ti-6Al-4V rau cov nres fasteners:
Tensile zog:950–1,050 MPa, piv rau Chav Kawm 10.9 cua sov-kho hlau
Yield zog:kwv yees li 880 MPa
Fatigue zog:50-60% ntawm qhov kawg tensile, qhov tseem ceeb rau kev tiv thaiv ntau lab lub voj voog
Thermal tuav:tuav kwv yees li 85% ntawm chav tsev- qhov kub thiab txias ntawm 400 degree, qhov kub thiab txias mus txog thaum muaj kev sib tsoo
Thermal expansion:8.6 × 10⁻⁶ /℃- nyob ze rau rotor thiab hub cov ntaub ntawv, txo qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txuas ntawm fastener
Galvanic compatibility:titanium yog galvanically nruab nrab nrog carbon fiber thiab txhuas, tiv thaiv cov galvanic corrosion uas tshwm sim thaum stainless hlau tiv nrog carbon composite
Cov khoom no ua rau Qib 5 titanium cov khoom ntawm kev xaiv rau MotoGP thiab World Superbike teams, qhov chaw nres tsheb fim huab cua caij tsheb kauj vab, thiab lub ntsia liaj qhov rooj yuav tsum tsis txhob so nws cov clamp load nruab nrab - haiv neeg.
CNC titanium machining: bar Tshuag rau bolt
Nrog tshaj 16+ xyoo ntawm kev paub, Shenzhen-raws liprecision CNC machiningchaw tsim tshuaj paus KEY-CNC tsim titanium rotor fasteners nyob rau hauv ib tug tswj multi-theem txheej txheem. Txhawm rau tswj kev coaxiality,CNC tigtsim cov ntsia liaj qhov rooj dawb paug los ntawm kev pom zoo Ti-6Al-4V bar Tshuag, tsim shank, xub pwg, thiab lub taub hau geometry hauv ib chucking. Qhov qis modulus ntawm elasticity thiab ua hauj lwm-hardening ntawm titanium xav tau cov cuab yeej ntse carbide, tswj cov nqi noj, thiab kev ua haujlwm nruj, uas KEY-CNC CNC tig chaw thiab cov neeg ua haujlwm tau txais kev cob qhia.
Xov dovhloov txiav threading rau load- bearing threads. Rolling compresses cov qauv nplej ntawm cov xov hauv paus es tsis txhob txiav nws, tsim cov xov nrog kev qaug zog ntau dua rau lub fastener uas yuav raug torqued, cua sov-cycled, thiab re-torqued pua pua zaus. ISO 965 chav kawm 6g xov tolerances muab lub kaus mom rotor lossis cov neeg nqa khoom sib cuag yam tsis muaj hla - xov.
Precision polishing muab nyiaj -grey tiav, thaumHom II anodisingtxheeb xyuas cov xim (kub, xiav, ntshav, ntsuab, dub, zaj sawv). Zoo li zinc plating ntawm steel bolts, anodising tsim ib txheej titanium oxide ruaj khov uas tsis nti lossis tev. Cov xim yog muaj nyob rau saum npoo.
Anti-Galling, Torque, thiab Installation Considerations
Titanium tsis tshua muaj thermal conductivity thiab nyiam rau gall (txias-weld) tiv thaiv nws tus kheej los yog stainless hlau ua kom zoo installation tseem ceeb rau Titanium Brake Rotor Bolts.
Anti- txeeb yog yuav tsum tau:
Ib zaj duab xis nyias ntawm tooj liab-raws li lossis npib tsib xee-raws li kev tiv thaiv- txeeb chaw yuav tsum tau siv rau cov xov ua ntej kev teeb tsa. Yog tsis muaj nws, titanium- ntawm- txhuas lossis titanium- ntawm - cov xov hlau cuam tshuam tuaj yeem txeeb tau thaum lub sij hawm nruj los yog tshem tawm, muaj peev xwm xav tau kev rhuav tshem.
Torque qhov tseem ceeb txawv ntawm steel:
Titanium bolts ntsia tau qhuav tuaj yeem tshwm "nruj" ntawm qis torque nyeem vim muaj kev sib txhuam ntau dua. Ib txwm siv lub chaw tsim khoom lub zog torque spec rau titanium, tsis yog steel - tus nqi sib npaug. Raws li kev siv dav dav, M6 titanium rotor bolts feem ntau yog torqued rau 8-10 N·m, M8 txog 22–27 N·m, thiab M10 txog 35–42 N·m - tab sis ib txwm ncua mus rau lub tsheb tsim cov lus qhia.
Xov engagement:
Qhov tsawg kawg nkaus ntawm 1.5 × lub nominal bolt txoj kab uas hla ntawm xov kev koom tes yog pom zoo rau tag nrho clamp load txoj kev loj hlob. TSEEM CEEB-CNC teeb tsa cov ntsia hlau ntev rau daim ntawv thov, suav nrog cov kev cai rau rotor spacers lossis ntxhua khaub ncaws.
Reusability:
Titanium rotor bolts tuaj yeem rov qab siv tau yog tias cov xov thiab cov kabmob tau raug tshuaj xyuas thiab tsis muaj kev puas tsuaj. Txawm li cas los xij, hauv kev sib tw siv, kev hloov pauv raws sij hawm raug pom zoo tom qab lub caij sib tw tag nrho.
Siv: Motorcycle, Motorsport thiab Performance Automotive
Cov titanium fasteners no yog siv nyob rau hauv txhua daim ntawv thov uas yuav tsum tau txo unsprung loj thiab corrosion kuj rau kev txhim kho kev ua tau zoo ntawm lub nres system:
- Motorcycles: Racing & Sport.Bolt- ntawm disc rotors rau cov tsheb kauj vab. Txo spinning pawg txhim kho tig- hauv thiab nres xav.
- Taug txuj kev nyuaj thiab ncig xyuas tsheb kauj vab:Titanium tus kheej -kho oxide txheej zam bolt seizing nyob rau hauv aluminium carriers tom qab xyoo ntawm txoj kev ntsev, dej hla dej thiab ntug hiav txwv huab cua.
- Motorsport (tsheb thiab karts):Lub Sijhawm Tawm Tsam, kev sib tw ua siab ntev thiab karting pab pawg sib pauv steel rotor bolts rau cov sib zog kom txo qis qhov hnyav, nrog rau 1: 4 unsprung - rau - sprung huab hwm coj piv ua txhua gramme ntau dua ib gramme hauv chassis - sib npaug hnyav.
- Tsheb kauj vab Performance:Roob tsheb tuam thiab downhill disc nres rotor bolts qhov twg titanium lub galvanic compatibility nrog carbon fiber hubs minimizes galvanic corrosion uas yuav tshwm sim los ntawm stainless hlau.
- Restoration thiab kev cai tsim- Hloov rusty steel fasteners ntawm keeb kwm maus taus thaum thawj bolts tau txeeb nyob rau hauv txhuas hubs thiab kev puas tsuaj tshem tawm yog tsim nyog.
Cov lus nug nquag
Q: Puas yog Titanium Brake Rotor Bolts zoo li steel bolts?
A: Yog lawm, thaum ua los ntawm Qib 5 Ti-6Al-4V, uas muaj 950-1,050 MPa tensile lub zog zoo li Chav Kawm 10.9 cov hlau kho cua sov. Vim nws qhov ntom ntom, titanium yog 45% sib dua thiab muaj zog dua. Tsis txhob siv Qib 2 ua lag luam ntshiab titanium rau nres vim nws lub zog tensile ~ 345 MPa tsis txaus.
Q: Puas yog titanium rotor ntsia liaj qhov rooj installation xav tau los tiv thaiv - txeeb?
A: Yog lawm, tiv thaiv - txeeb yog tsim nyog. Titanium txwv thermal conductivity thiab galling nyiam ua rau qhuav titanium threads tiv thaiv txhuas los yog hlau mus txeeb thaum lub sij hawm installation los yog tshem tawm. Ua ntej torqueing, kho threads thiab bolt taub hau nrog ib tug nyias, txawm lub tsho tiv no ntawm tooj liab - los yog npib tsib xee-raws li anti- txeeb. Torque-rau-clamp hloov dua siab tshiab kuj zoo ib yam.
Q: Puas yog KEY-CNC ua cov taub hau thiab cov xim anodized?
A: Yog. Kev cai Titanium Brake Rotor Bolts nrog tsis yog- tus qauv ntev, flanged taub hau, countersunk taub hau, thiab rub- nplhaib tsim kom ceev- hloov rotors yog ua rau koj daim duab. Hom II anodising los ntawm kub, xiav, ntshav, ntsuab, dub, thiab zaj sawv. Sau nrog 2D daim duab lossis STEP cov ntaub ntawv.
Q: Qhov siab tshaj plaws ua haujlwm kub rau titanium rotor bolts?
A: Ntawm 400℃(752℃F), Qib 5 Ti-6Al-4V khaws 85% ntawm nws chav tsev kub. Qhov no yog qhov kub thiab txias ntawm tus nres rotor mounting kho vajtse thaum muaj kev txhoj puab heev thiab khiav haujlwm. Hu rau peb cov engineers rau cov ntawv thov kev ua si loj thaum rotor kub tshaj 600 degree. Titanium yog qhov ruaj khov tab sis yuav tsum tau hloov cov txheej txheem torque kom tso cai rau thermal expansion.
