Ntau tus tswv tsheb pom lawv tus kheej tawg thaum nws los hloov lawv lub log: qhov twg zoo dua, steel log lossis alloy log? Qhov tseeb, tsis muaj lus teb meej rau lo lus nug no. Ob leeg steel thiab alloy log muaj lawv tus kheej zoo, tab sis tsuav yog lawv haum koj xav tau kev tsav tsheb, koj tuaj yeem ua tiav qhov kev tsav tsheb uas koj xav tau. Hlau thiab alloy log yog ob hom sib txawv ntawm lub log, muaj qhov sib txawv ntawm cov khoom siv, kev ua tau zoo, tus nqi thiab tsim nyog rau cov xwm txheej sib txawv. Tam sim no peb yuav xaus qhov sib txawv ntawm ob qhov kev nthuav dav thoob plaws ntau qhov ntev, los pab koj xaiv lub log zoo raws li koj qhov kev xav tau tshwj xeeb.
Qhov sib txawv ntawm steel log thiab alloy log
Cov khoom siv thiab cov txheej txheem tsim khoom
Cov log hlau feem ntau yog tsim los ntawm stamping thiab vuam qis - carbon steel. Lawv muaj pes tsawg leeg yog hlau-raws li, nrog me me ntawm manganese, silicon thiab lwm yam ntxiv los txhim kho lub zog. Cov txheej txheem tsim khoom yog ncaj nraim thiab tus nqi- ua tau zoo, nrog tus nqi ntawm tus kheej feem ntau yog li ntawm 200 txog 500 yuan. Aluminium alloy log, ntawm qhov tod tes, feem ntau yog tsim los siv casting (rau cov neeg caij tsheb txheem) lossis forging (rau siab - qauv ua haujlwm). Cov khoom tseem ceeb yog aluminium-silicon-magnesium alloy, thaum qee cov khoom siv siab- kawg siv siab- lub zog forged aluminium alloys xws li 7075. Cov txheej txheem tsim khoom yog qhov nyuaj thiab xav tau ntau dua, nrog rau cov nqi ntawm ib lub log xws li 500 txog 3,000 thiab ntau dua. Nyob rau hauv cov nqe lus ntawm cov khoom tseem ceeb, rau tib qhov loj, steel log hnyav kwv yees li 10-12 kg, thaum aluminium alloy log hnyav tsuas yog 6-8 kg, sawv cev qhov hnyav sib txawv ntawm ib ncig ntawm 30%. Qhov tsis sib xws no cuam tshuam ncaj qha rau ntau yam ntawm lub tsheb ua haujlwm.
Cov yam ntxwv tseem ceeb
Peb yuav tshuaj xyuas qhov no los ntawm peb qhov kev txhawj xeeb tshaj plaws rau cov tswv tsheb: kev siv roj, tuav thiab lub zog. Hais txog kev siv roj, muaj kev pom zoo nyob rau hauv kev lag luam uas '1 kg ntawm unsprung hnyav sib npaug 5-10 kg ntawm sprung hnyav'. Lub teeb yuag zoo ntawm aluminium alloy log tuaj yeem txo qhov hnyav tsis muaj zog thiab txo qis zog poob; Feem ntau, 10% txo qis hauv lub tsheb qhov hnyav tag nrho ua rau 6-8% txo qis hauv roj noj. Nyob rau lub sijhawm ntev - kev mus los hauv nroog, qhov no tuaj yeem ua rau muaj txiaj ntsig zoo ntawm cov nqi roj hauv ib xyoos. Cov log hlau, ntawm qhov tod tes, hnyav dua thiab muaj zog dua inertial, tso lub nra hnyav dua rau ntawm lub cav. Nyob rau hauv cov xwm txheej zoo ib yam, roj noj ib 100 kilometers yog 0.3-0.5 liters siab dua nrog aluminium alloy log.
tuav
Lub teeb yuag aluminium alloy lub log txo qis kev sib hloov inertia, txhim kho lub tsheb nrawm teb los ntawm 0.3-0.5 vib nas this thiab txo qis braking nrug raws li. Kev taw qhia pom tau tias sib dua thiab ua haujlwm ntau dua, thiab qhov sib txawv no tshwj xeeb tshaj yog pom thaum nres ntau zaus- thiab- mus hauv nroog tsav tsheb thiab tig ntse -ntau npaum li cas kev khiav hauv cov tsheb ciav hlau hnyav yog qhov nrawm dua li hauv cov tub rog hnyav khau. Cov log hlau, hnyav dua, muab cov lus teb qeeb qeeb. Nyob rau hauv high speeds, tsis txaus dynamic tshuav nyiaj li cas kuj yuav ua rau lub kauj tsheb vibrate, yog li cuam tshuam rau kev tsav tsheb.
Lub zog thiab Durability
Steel rims muab zoo heev toughness; lawv tsis zoo li yuav tawg thaum muaj kev cuam tshuam, tsuas yog deforming, thiab yooj yim thiab pheej yig los kho. Piv txwv li, tom qab me me deformation, lawv tuaj yeem raug ncaj thiab siv txuas ntxiv, ua rau lawv zoo heev rau txoj kev nyuaj xws li txoj kev pob zeb thiab cov chaw tsim kho. Qhov no yog vim li cas steel rims feem ntau siv rau cov tsheb thauj khoom thiab tsheb siv hluav taws xob. Txawm li cas los xij, steel rims yog qhov yooj yim rau xeb, thiab tsis tu ncua los tiv thaiv- kev kho corrosion yuav tsum tau siv sijhawm ntev -; txwv tsis pub, lawv lub neej kev pabcuam yuav raug cuam tshuam. Aluminium alloy log muaj siab hardness thiab lub zog compressive deb tshaj li cov hlau log. Kev sim cov ntaub ntawv qhia tau hais tias qhov siab tshaj plaws thauj khoom -cov kabmob muaj peev xwm ntawm kev siv aluminium alloy log tuaj yeem ncav cuag li 20 tonnes, hos steel log tsuas tuaj yeem tiv taus ib ncig ntawm 10 tonnes. Txawm li cas los xij, lawv yog cov nkig thiab tuaj yeem tsim cov kab nrib pleb zais lossis tawg thaum muaj kev cuam tshuam loj heev. Cov nqi kho yog siab, thiab hauv qhov xwm txheej hnyav, kev hloov pauv yog tsim nyog; yog li ntawd, lawv zoo dua rau siv rau ntev - lub sij hawm paving nto.
Thaum tshav kub kub Dissipation Performance
Aluminium alloy muaj cov thermal conductivity ntau tshaj peb npaug ntawm cov hlau, ua rau nws sai sai dissipate tshav kub generated los ntawm braking system thiab txo thermal ploj. Qhov no muab kev tiv thaiv zoo rau lub braking system, tshwj xeeb tshaj yog thaum lub sij hawm ntev - tsav tsheb deb, nquag nres los yog thaum nqis los ntev gradients, yog li txo qhov kev pheej hmoo ntawm log tsheb blowouts thiab txuas ntxiv lub neej kev pab cuam ntawm braking Cheebtsam. Nyob rau hauv sib piv, steel log yog feem ntau nyob rau hauv airflow rau tshav kub dissipation, uas yuav ua rau overheating ntawm lub nres discs thaum lub sij hawm nruam braking, yog li cuam tshuam kev ua haujlwm ntawm braking.
Kho kom zoo nkauj
Cov log hlau yuav muaj qhov yooj yim, monotonous tsim thiab feem ntau xav tau lub log npog kom zais lawv, thaum lawv cov kev xaiv tsim muaj tsawg. Aluminium alloy log, ntawm qhov tod tes, tuaj nyob rau hauv ntau yam qauv thiab tuaj yeem tsim cov qauv tsim xws li ntau- hais lus thiab qhib- hais lus teeb tsa. Ua ke nrog kev kho saum npoo xws li chrome plating thiab txhuam tiav, lawv tuaj yeem txhim kho lub tsheb zoo li qub, uas yog ib qho ntawm cov laj thawj tseem ceeb vim li cas lawv yog qhov kev xaiv tseem ceeb rau tsev neeg lub tsheb.
Yog tias koj txoj kev tsav tsheb feem ntau yog rau kev mus ncig hauv nroog thiab kev taug kev hauv nroog, thiab koj ua qhov tseem ceeb ntawm kev lag luam roj, kev tuav thiab kev pom zoo, thaum muaj peev nyiaj siv tau zoo, ces cov log hlau yog qhov kev xaiv zoo dua. Lawv qhov kev ua tau zoo tag nrho ua tau raws li qhov tseem ceeb ntawm tsev neeg lub tsheb, thiab lawv muaj kev thaj yeeb nyab xeeb ntau dua rau lub sijhawm ntev. Hloov pauv, yog tias koj lub tsheb nquag siv los thauj cov khoom hnyav, tawm - txoj kev, lossis tsav tsheb ntawm qhov chaw tsis muaj kev sib tsoo, thiab koj muaj peev nyiaj tsawg dua thaum tseem ceeb rau kev ua haujlwm ntev thiab cov nqi kho mob, ces cov log hlau yuav yog qhov kev xaiv zoo dua. Lawv cov kev cuam tshuam zoo heev thiab tus nqi -kev ua tau zoo ua rau lawv tiv tau zoo dua nrog cov kev nyuaj ntawm txoj kev.
Summary and Conclusions
Cov log hlau muaj txiaj ntsig zoo dua rau cov nyiaj thiab kev ua haujlwm ntev, thaum lub log alloy zoo tshaj plaws ntawm kev ua haujlwm tag nrho; tsis yog inherently superior rau lwm tus. Thaum txiav txim siab, tus yuam sij yog xav txog koj qhov kev tsav tsheb tiag tiag thiab cov ntsiab lus tseem ceeb -qhov kev xaiv zoo tshaj yog qhov uas haum rau koj zoo tshaj plaws. Txawm hais tias koj tab tom nrhiav tus nqi tsim nyog rau cov nyiaj los yog ua kom muaj kev ua tau zoo thiab kev zoo nkauj, ib zaug koj tau qhia meej koj cov kev xav tau, koj tuaj yeem zam tau yooj yim zam qhov teeb meem.
