Dab tsi yog cov kev xav tau ntawm kev ua tau zoo rau kab kev ua si hauv cov ntawv thov hauv tsheb?
Thaum xaiv thiab kev tsim kho cov khoom siv tsheb, muaj ntau cov engineters tuav cov kev ua kom tsis muaj tseeb txog "kev xav tau kev ua haujlwm rauTawm Shafts nyob rau hauv cov ntawv thov lag luam. "Qee tus ncaj qha siv cov qauv kev ua tau zoo ntawm cov khoom lag luam uas tsis zoo, thiab ntau yam kev ua kom zoo nkauj). txawm tias kev nyab xeeb kev nyab xeeb hauv tsheb tom qab yuav tsum muaj qhov chaw ua haujlwm hauv tsheb Corrosion. Niaj hnub no, peb zom cov ntsiab lus tseem ceeb, thov kom paub tseeb kev sib txawv, muab cov kev taw qhia meej rau kev xaiv thiab R & D.
Ua ntej, hais meej: kev sib txheeb ntawm txoj kev sib txheeb ntawm tsheb Apotive Actuator Daim Ntawv Thov thiab Kev Ua Tau Zoo
Automotive linear awuats yog feem ntau siv rau hauv kev ua haujlwm zoo xws li lub rooj kev ua yeeb yam, nres / npuaj teg tso tawm hauv cov tsheb hluav taws xob hluav taws xob tshiab.
Qhov txawv txav kev ua haujlwm ntawm cov xwm txheej no ncaj qha rau cov kev ua tau zoo tshaj plaws, ua lub hauv paus rau kev nkag siab:
Lub rooj zaum kev hloov kho:Yuav tsum tiv thaiv tib neeg thauj khoom (50 {-}} 150kg) thiab siab} zaus reciprocating suab (10-50 cmles txhua hnub). Cov tub ntxhais kawm tau pw hauv "kev sib txhuam tsis tshua muaj kev sib txhuam, cov suab tsis tshua muaj zog" los xyuas kom muaj kev kho kom haum thiab ntev ntev.
Qhov rai / Sunroof System:Raug los nag, plua plav, thiab huab cua sov (-30 degree), nws cov tub ntxhais kev ua tau zoo, thiab kev sib txuas lus zoo dua "kom tiv thaiv kom tsis txhob pom kev thiab xau.
Nres / Clutch System:Kev cuam tshuam ncaj qha rau tsav tsheb kev nyab xeeb, nws yuav tsum tau muab cov thurust intantantaneous (200-500n) thiab ua kom muaj kev mus ncig. Cov ntsiab lus kev ua tau zoo yog "high rigidity, muaj lub luag haujlwm loj, thiab xoom lag xim" kom tiv thaiv nres tsis ua haujlwm.
Tshiab lub tsheb hluav taws xob tsheb roj teeb pob system:Txhawb cov khoom siv hnyav (300-800KG) thiab xav kom thaiv kev tiv thaiv hluav taws xob xau. Cov tub ntxhais kev ua tau zoo tshaj plaws yog "muaj peev xwm siab, rwb thaiv tsev, kev co tiv taus roj teeb thiab lub tsheb sib npaug.
Thib ob, cov kev ua tau zoo yuav tsum muaj rau cov qauv ua lag luam: cov qauv tseem ceeb rau txhua daim ntawv thov
Txawm hais tias lub kaw lus lawv ua haujlwm li cas, kho tsheb ua lag luam ua kom tau raws li cov ua haujlwm tseem ceeb hauv qab no thiab kev nyab xeeb, tsis muaj kev zam:
1. Cov Cuab Yeej Kho Tshuab: Core rau Thauj Txhawb thiab deformation Kuj
Qoob qaug zog:Yuav tsum wringand hla ib lab reciprocrating tsis muaj kev tawg, nrog kev ua kom qaug zog ntau dua lossis sib npaug nrog 5}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} 8 xyoo automotive lub neej). Kev ua rog dhau los tshawb xyuas qhov tseeb tias tom qab 1 lab los mus rau hauv cov khoom siv tsis muaj zog thiab sib luag ntawm 0.02mm kom tau raws li kev pabcuam ntev.
2. Kev Tawm Tsam Kev Ua Tau Zoo: Ua kom meej meej thiab xis nyob
Cov lus tsa suab kev ua tau zoo ntawm linear coj ncaj ncaj cuam tshuam ncaj qha cuam tshuam kev tsav tsheb, uas xav tau cov kev sib txhuam uas tsis tshua muaj kev sib txhuam, thiab muaj suab nrov tsawg:
Kev sib txhuam coefficient:Los ntawm kev sib raug zoo nrog lubricants (piv txwv li, lithium- Raws li cov roj, polyurea roj yuav tsum tau tsawg dua lossis sib npaug 0.005 kom txo lub zog muaj zog thiab kev siv zog.
Thib peb, kev ua tau zoo yuav tsum muaj kev sib txawv los ntawm daim ntawv thov: tsom kho kom tsis txhob muaj overteresign
Cov ntsiab lus kev ua tau zoo yuav tsum tau ua lub hauv paus, tab sis sib txawv sib txawv tas "cov txuj ci tshwj xeeb" nyob rau sab saum toj ntawm lub hauv paus no.
Qhov no tiv thaiv 'overceign' uas nce nqi lossis "kev ua tau zoo kawg" uas ua rau tsis tiav:
1. Lub Ris Kho Cov Kab Tawm Tawm Cov Kab Tawm: Hais txog "durability thiab xis nyob"
Yuav Tsum Tau Ntxiv Ntxiv:
Kev ua tiav tau ntau dua lossis sib npaug ntawm 200N tus kheej - xauv lub zog los ntawm kev sib koom tes ntawm cov ncej txhav tas.
2. Qhov rai / Sunroof System Tawm Dress: tsom rau "ib puag ncig kev zam thiab sib khi"
Yuav Tsum Tau Ntxiv Ntxiv:
Huab cua Kuj:Yuav tsum tiv thaiv UV raug (simulating 5 xyoos ntawm lub hnub sab nraum zoov raug) tsis muaj txheej txheej saum npoo av lossis tev. Tom qab 50 thermal mus los ntawm -40 Qib rau 80 Degree, tshem cov kev hloov pauv qis dua lossis sib npaug rau 0.01mm.
Waterproof Sealing:Slider -} rau -}} meter} 'meter' aywing ingress thiab corrosion. Cov ncej tshav ntuj ua hauj lwm rau ob-di ncauj cim rau cov dej hauv tsev lossis mating tsis muaj dej sab hauv tom qab IPx7;
3. Nres / clutch system kab ncej: hais txog "kev nyab xeeb thiab qhov tseeb"
Yuav Tsum Tau Ntxiv Ntxiv:
Kev Cuam Tshuam:Nyob rau hauv intantaneous cuam tshuam loads (piv txwv li, 500n thrust thaum lub sij hawm thaum muaj xwm ceev, nrog rau kev sib txawv me me lossis sib npaug rau 0.02mm / m.
Ncig ua teb chaws:Mus ncig ua yuam kev tsawg dua los yog sib npaug ± 0.1mm thoob plaws stroke (feem ntau 50-100mm), ua kom cov kab ntawv sib txuas lus ntawm txoj kev mus ncig ua si thiab ua haujlwm. Tus kab mob braking nrog 100mm puv kev raug mob tawm tsam tsuas yog ± 0.08mm Mus ncig ua si, xa cov lus ruaj khov thaum lub sijhawm nres;
4. Tawm Shafts Rau Tshiab Tsheb Cov Khoom Hluav Taws Xob Cov Khoom Hluav Taws Xob Cov Khoom Hluav Taws Xob
Yuav Tsum Tau Ntxiv Ntxiv:
High Load Muaj Peev Xwm:Rated Static Static Thauj ntau dua los yog sib npaug rau 1000kg, ntsuas cov khoom siv zog ruaj khov dua lossis sib npaug ntawm 800kg. Deformation tom qab ntev - sij hawm chaw thau khoom (5 xyoos) tsawg dua los yog sib npaug lossis sib npaug ntawm cov roj teeb pob.
Rwb thaiv tsev kev ua haujlwm:Ncej deg yuav tsum tau ib qho txheej txheem insulating (piv txwv li, polyimide), nrog kev tiv thaiv kom tiv thaiv roj teeb tam sim no los ntawm kev coj mus rau lub tsheb tsav tsheb. Cov roj teeb pob tawm tawm cov txheej ua tiav 150Mω rwb thaiv tsev tsis kam, sib ntsib {{voltage kev nyab xeeb qauv;
Plaub, hom kev tsis ntseeg siab: zam teeb meem tsim kev ua tau zoo vim kev nkag siab
1. Kev tsis ncaj ncees 1:"Cov kev ntsuas siab dua yog qhov zoo dua; nrhiav kom muaj IT3 qib precision ua kom muaj kev cia siab ntau dua."
Kev nrhiav ntau dhau ntawm qhov siab precision tseem ceeb ntau yam tsis muaj txiaj ntsig zoo. Piv txwv, nws yog6 precision (ncaj 0.1mm / m) rau kev kaw kev hloov khoTawm Shafts twb tau raws li qhov yuav tsum tau ua. Kev kho dua tshiab rau IT3 (0.02mm / m) nce machining nqi los ntawm 50% tsis muaj kev txhim kho hauv kev tsav tsheb, constituting cov khoom pov tseg.
2. Kev ua txhaum cai 2: "Yog tias ib qho kev ntsuam xyuas sim dhau, nruab rau hauv tsheb yuav yog cov teeb meem {2} Pub dawb."
Kev kuaj sim yog lub hauv paus, tab sis tiag -} ntiaj teb txoj kev xeem yog qhov tseem ceeb. Ib txoj kab sib tw dhau los 1 lab nkees ua voj voog hauv kev kuaj sim tab sis nthuav tawm cov ris nrawm tom qab 50,000 km ntawm kev sim. Kev tshawb nrhiav tau tshwm sim unaccounted - rau kev co - inducts loads. Kev ua kev co simulation rau hauv kev kuaj sim yog qhov tseem ceeb rau tiag- ntiaj teb kev raug.
Lub ntsiab
Cov ntsiab lus tseem ceeb yuav tsum muaj rauTawm Shafts Hauv cov ntawv thov automotive yog "scenario admination, ntau -} {{1} {txheej txheem kev paub tseeb." Raws li cov kev ua haujlwm tseem ceeb (tshuab zog, meej, ib puag ncig kev yoog, peb tuaj yeem tsim kho cov qauv txheej txheem thiab kev ntsuas cov qauv. Qhov no tiv thaiv kev tsav tsheb tsis txaus los ntawm kev ua tau zoo ntawm kev ua tsis tau zoo, txhim kho kev pab kho tsheb thiab kev nyab xeeb.
