Kev lag luam tsheb nyob sab Europe muaj npe nrov rau nws cov qib siab thiab muaj tswv yim tshiab. Nrog rau kev txhawb nqa ntawm kev txuag hluav taws xob thiab kev txo qis emission txoj cai, txhawm rau txo qis kev siv roj thiab carbon dioxide emissions, txhim kho thiab tsim kho tshiab aluminium alloys yog siv dav hauv kev tsim tsheb. Raws li kev txheeb cais, nyob rau hauv kaum xyoo dhau los, qhov nruab nrab ntawm txhuas siv nyob rau hauv cov neeg nrog caij tsheb tau nce ob npaug, thiab qhov hnyav txo ntawm aluminium alloys yog qhia hauv daim duab 1 hauv qab no. Raws li cov tswv yim tsim tshiab, qhov kev sib txawv no yuav txuas ntxiv mus rau ob peb xyoos tom ntej no.
Nyob rau hauv tus txheej txheem ntawm kev txhim kho lub teeb yuag, aluminium alloys tab tom ntsib kev sib tw hnyav nrog lwm cov ntaub ntawv tshiab, xws li cov hlau muaj zog, uas tseem tuaj yeem tuav lub zog siab tom qab nyias-walled tsim. Tsis tas li ntawd, muaj magnesium, titanium, iav los yog carbon fiber composite cov ntaub ntawv, cov tom kawg uas twb lug siv nyob rau hauv aerospace. Tam sim no lub tswv yim ntawm ntau cov khoom tsim tau raug muab tso rau hauv kev tsim tsheb, thiab kev siv zog los siv cov ntaub ntawv tsim nyog rau qhov tsim nyog. Ib qho kev sib tw tseem ceeb yog qhov teeb meem ntawm kev sib txuas thiab kev kho saum npoo, thiab ntau yam kev daws teeb meem tau tsim, xws li lub cav thaiv thiab lub zog tsheb ciav hlau, thav duab tsim (Audi A2, A8, BMW Z8, Lotus Elise), nyias phaj qauv (Honda NSX. , Jaguar, Rover), ncua kev kawm ntawv (DC-E chav kawm, Renault, Peugeot) thiab lwm yam structural Cheebtsam tsim. Daim duab 2 qhia txog cov khoom ntawm txhuas siv hauv tsheb.
BIW Design Strategy
Lub cev-hauv-dawb yog qhov hnyav tshaj plaws ntawm lub tsheb qub, suav txog 25% txog 30% ntawm lub tsheb qhov hnyav. Muaj ob txoj kev tsim qauv hauv lub cev-hauv-dawb tsim.
1 "Profile space frame design" rau cov tsheb me thiab nruab nrab: Audi A8 yog ib qho piv txwv, lub cev dawb hnyav 277 kg, muaj 59 profiles (61 kg), 31 castings (39 kg) thiab 170 daim hlau (177 kg). Lawv koom nrog riveting, MIG vuam, laser vuam, lwm yam hybrid vuam, gluing, thiab lwm yam.
2. "Die-forged sheet hlau monocoque qauv" rau nruab nrab mus rau loj-muaj peev xwm siv tsheb: Piv txwv li, Jaguar XJ (X350), 2002 qauv (raws li qhia hauv daim duab 4 hauv qab), 295 kg loj "stamped lub cev monocoque qauv" lub cev-hauv-dawb muaj 22 profiles (21 kg), 15 castings (15 kg) thiab 273 daim hlau qhov chaw (259 kg). Cov kev sib txuas muaj xws li kev sib txuas, riveting, thiab MIG vuam.
Daim ntawv thov ntawm Aluminium Alloy rau lub cev
1. Hnub nyoog hardened Al-Mg-Si alloy
6000 series alloys muaj magnesium thiab silicon thiab tam sim no siv nyob rau hauv tsheb lub cev los xij xws li A6016, A6111 thiab A6181A. Hauv Tebchaws Europe, 1-1.2mm EN-6016 muaj qhov zoo heev formability thiab corrosion kuj thiab yog dav siv.
2. Tsis-kub kho tau Al-Mg-Mn alloy
Vim nws qhov tshwj xeeb siab tawv tawv, Al-Mg-Mn alloys nthuav tawm zoo heev formability thiab siab zog, thiab yog dav siv nyob rau hauv automotive kub dov thiab txias-dov los xij thiab hydroformed hlab. Daim ntawv thov nyob rau hauv lub chassis lossis lub log yog qhov ua tau zoo dua vim tias qhov txo qis ntawm qhov tsis muaj qhov txav mus los ntxiv rau kev txhim kho kev tsav tsheb thiab txo cov suab nrov.
3. Aluminium profile
Nyob rau hauv cov teb chaws Europe, tag nrho cov tsheb tshiab tswv yim tau npaj raws li txhuas profile tsim, piv txwv li, aluminium alloy thav duab thiab complex substructures. Lawv lub peev xwm zoo rau cov qauv tsim thiab kev sib koom ua ke ua rau lawv zoo tshaj plaws rau cov nqi tsim khoom lag luam. Vim hais tias quenching yuav tsum tau thaum lub sij hawm extrusion, nruab nrab lub zog 6000 thiab siab zog 7000 hnub nyoog hardenable alloys yog siv. Formability thiab lub zog kawg yog tswj los ntawm lub hnub nyoog hardening los ntawm cov cua kub tom ntej. Aluminium alloy profiles feem ntau yog siv rau hauv thav duab tsim, sib tsoo kab teeb thiab lwm yam sib tsoo.
4. Aluminium casting
Castings yog cov khoom siv txhuas feem ntau siv hauv tsheb, xws li cov cav cav, lub tog raj kheej taub hau thiab cov chassis tshwj xeeb. Txawm tias cov cav tov diesel, uas tau nce lawv txoj kev lag luam ntau hauv cov teb chaws Europe, tab tom hloov mus rau aluminium castings vim qhov kev xav tau ntxiv rau lub zog thiab kav ntev. Nyob rau tib lub sijhawm, aluminium castings kuj tseem siv rau hauv cov qauv tsim, ncej qhov chaw thiab cov khoom siv, thiab kev ua haujlwm siab ntawm AlSiMgMn aluminium alloys tshiab tau ua tiav ntau zog thiab ductility.
Aluminium yog cov khoom ntawm kev xaiv rau ntau daim ntawv thov tsheb xws li chassis, lub cev thiab ntau yam khoom siv vim nws qhov ntom ntom, zoo formability thiab zoo corrosion kuj. Aluminium siv nyob rau hauv lub cev qauv tsim muaj peev xwm ua tau tsawg kawg yog 30% qhov hnyav txo nyob rau hauv qhov chaw ntawm lub rooj sib tham yuav tsum tau ua. Tsis tas li, aluminium alloys tuaj yeem siv rau feem ntau ntawm cov npog tam sim no. Qee qhov xwm txheej uas xav tau lub zog siab, 7000 series alloys tseem tuaj yeem tswj tau qhov zoo. Yog li ntawd, rau cov ntawv thov ntim siab, aluminium alloy qhov hnyav txo cov kev daws teeb meem yog txoj kev pheej yig tshaj plaws.
