Raws li qhov yuav tsum tau ua ntawm cov kev cai ntawm tus ncej, cov qauv ntawm lub tsheb sib tw yuav tsum muaj ob lub yob tawb nrog kev txhawb nqa, pem hauv ntej bulkhead nrog kev txhawb nqa system thiab tsis qauv, thiab sab tiv thaiv kev sib tsoo qauv, uas yog, lub nplhaib tseem ceeb, lub nplhaib pem hauv ntej. , yob tawb slant kev them nyiaj yug thiab nws cov qauv kev txhawb nqa, sab tiv thaiv kev sib tsoo qauv, pem hauv ntej bulkhead, thiab pem hauv ntej bulkhead kev txhawb nqa system.Tag nrho cov thav duab units tuaj yeem hloov lub nra ntawm tus neeg tsav tsheb tswj qhov system mus rau cov qauv yooj yim.Chav tsev thav duab yog hais txog qhov luv tshaj plaws, tsis raug txiav, thiab txuas ntxiv ib tus yeeb nkab fittings.Ib qho ntawm cov haujlwm ntawm lub thav duab yog los tiv thaiv ntau yam kev thauj khoom los ntawm sab hauv thiab sab nraud ntawm lub tsheb, tab sis cov khoom siv ntawm ntau yam khoom sib txawv heev, ua rau nws nyuaj rau cov neeg tsim qauv thiab cov neeg txiav txim los txiav txim seb lub thav duab lub peev xwm ua tau raws li cov qauv.Alloy steel yog cov hlau carbon hlau tsim los ntawm kev ntxiv qhov tsim nyog ntawm ib lossis ntau dua alloying ntsiab rau cov pa roj carbon zoo tib yam.Los ntawm kev ntxiv cov khoom sib txawv thiab siv cov txheej txheem sib txawv, cov khoom tshwj xeeb xws li lub zog siab, siab toughness, hnav tsis kam, corrosion kuj, kub tsis kam, kub tsis kam, thiab tsis muaj hlau nplaum yuav tau.Thiab peb tus protagonist lub npe tag nrho yog 30CrMo Pipe, tseem hu ua 4130 Steel Pipe.Nws muaj zog thiab toughness, zoo hardenability, thiab hardenability txoj kab uas hla ntawm 15-70 hli nyob rau hauv cov roj.Cov hlau muaj lub zog thermal zoo, xws li ntawm 500 ˚ Hauv qab C, nws muaj lub zog kub txaus thiab kev ua haujlwm vuam zoo.
4130 qib hauv tsev 30CrMo yog cov hlau alloy uas muaj chromium thiab molybdenum, nrog lub zog tensile feem ntau siab dua 750MPa.Feem ntau pom nyob rau hauv kev ua lag luam yog tuav thiab tuab daim hlau.Nyias phab ntsa 4130 steel yeeb nkab yuav siv los ua lub tsheb kauj vab ncej, .Qhov no yog ib tug detachable steel yeeb nkab los ua ke.Nws yog ua los ntawm txias kos seamless carbon steel kav khoov thiab ntsia ib los ntawm ib tug raws li contour ntawm sab hauv ntawm lub carriage.Yog tias koj tshem lub plhaub lub cev, koj yuav pom ib lub tawb hlau ua los ntawm ob peb lub kav hlau.Yog li ntawd, cov neeg Hongkongers kuj hu nws "roll tawb".Nrog rau cov pob zeb diamond uas muaj nuj nqis no, txawm tias lub tsheb dov ob peb zaug thiab sab nrauv ntawm lub tsheb tsis tuaj yeem tiv taus, cov neeg sib tw sab hauv tseem yuav muaj kev nyab xeeb thiab suab.Cov khoom siv steel yeeb nkab thiab twist tsis kam siv rau kev tiv thaiv yob thav duab yog txiav txim siab los ntawm qhov hnyav ntawm lub tsheb lub cev, thiab feem ntau yuav tsum muaj peev xwm tiv taus qhov cuam tshuam ntawm ntau tshaj ob npaug ntawm qhov hnyav ntawm lub tsheb lub cev.Raws li txoj kev ntawm txoj kev sib tw khiav yog qhov tiaj tus, yuav luag tsis muaj qhov sib txawv.Nyob rau hauv sib piv, yog Rallying ntawm txoj kev roob thiab kev sib tw hla teb chaws nyob rau hauv qus overturn, lub cev puas tsuaj yuav ntau dua.Yog li ntawd, lub zog ntawm yob tawb rau kev sib tw sib tw thiab kev sib tw hla teb chaws yog siab dua, thiab cov qauv ntawm cov yeeb nkab fittings yog denser.Cov kws tshaj lij tau teeb tsa los tiv thaiv yob thav duab tuaj yeem tsis tsuas yog tiv thaiv cov xwm txheej npaj txhij txog, tab sis kuj txhim kho lub zog thiab tiv thaiv kev sib tw ntawm lub cev tsheb.Piv txwv li, los ntawm kev sib txuas ob peb txoj haujlwm vuam ntawm cov yob tawb mus rau pem hauv ntej thiab nram qab lub rooj zaum shock absorber, txawm tias lub tsheb nquag dhia, ib feem ntawm qhov cuam tshuam los ntawm hauv av yuav tawg mus rau hauv lub tawb yob, uas muab kev tiv thaiv rau lub tsheb. lub cev tsheb.
4130 feem ntau yog siv hauv kev lag luam dav hlau, tab sis thaum ntxov mus rau nruab nrab-1950s, thaum nws nkag mus rau hauv kev sib tw chassis qauv, qhov xwm txheej pib hloov.Ib yam li kev lag luam aviation, kev siv 4130 ua lub ntsiab chassis cov khoom siv hauv kev sib tw tau maj mam tsim ntau xyoo.Lub sijhawm ntawd, ntau tus neeg tsav tsheb sib tw tau nug txog qhov muaj peev xwm vuam ntawm 4130, vim tias TIG vuam yog cov cuab yeej tshiab heev, thiab cov tuam txhab feem ntau siv brazing rau vuam cov khoom no.Nws tsis yog txog xyoo 1953 uas Boeing Aircraft Company tau sau tseg thiab pib TIG vuam ntawm nws cov qauv 4130.Nws tsis tuaj yeem txiav txim siab lub chassis ntawm thawj 4130 lub tsheb, tab sis nws yog qhov yuav tsum tau siv thawj zaug hauv kev sib tw tsheb, xws li SCCA tsheb, lub tsheb roj sab saum toj, IndyCar lossis Formula One.
Los ntawm nruab nrab-1950s, ntau lub tsheb ua los ntawm 4130 tau sib tw hauv ntau theem kev sib tw uas tau lees paub los ntawm SCCA.Xyoo 1953, Forest Edwards tau tsim lub Edwards/Blue Speical siv lub 51 xyoo Morris sedan thiab 4130. Charles Hall yuav tsav nws "me ntsis excavator" los yeej SCCA H-chav kawm hloov kho Pacific Coast Championship, uas siv 1.25 ntiv tes × A trapezoidal ncej. ua los ntawm 0.030 nti 4130.
Dragmaster Dart: Dodd Martin thiab Jim Nelson, nrog rau lawv cov Dragmaster Dart, tau tsim lub tuam txhab Dragmaster hauv Carlsbad, California nyob rau hauv kwv yees li 1959 lossis 1960. Lawv yog tus thawj coj ntawm kev sib tw tshuab thiab tau yeej "Zoo Tshaj Plaws" hauv NHRA kev sib tw hauv tebchaws.Tsis pub dhau ib xyoos ntawm kev qhib, Dragmaster pib tsim lub chassis hu ua "Dart", uas los ntawm ob yam khoom: 4130 thiab me me hlau.
Nyob rau hauv 1965, lub Brawner Hawk, lub rear engine ua los ntawm 4130, ua nws debut thiab tau tsav los ntawm Mario Andretti.Brawner Hawk tau tsim los ntawm tus kws kho tsheb legendary Clint Browner thiab nws tus thwjtim Jim McKee thaum lub sijhawm.Nws tau tsim los ntawm Copper Climax, thawj lub tsheb cav tsheb nkag mus rau 500 mais pib kab hauv Is Nrias teb hauv xyoo 1961, tau tsav los ntawm ob zaug Formula One tus yeej Jack Brabham.Xyoo ntawd, nyob rau hauv Mario txoj kev tsav tsheb, Braun Hawk tau ua tiav zoo.Ntawm Husserl Grand Prix tuav ntawm Indianapolis Circuit Park, Mario yeej thawj tsib qhov chaw hauv plaub qhov kev sib tw tsim nyog, ib txoj haujlwm ncej thiab tsib qhov chaw saum toj kawg nkaus, nrog rau nws thawj zaug yeej hauv USAC.Nws kuj tau yeej qhov kev sib tw xyoo 1965 ntawm USAC thiab xyoo 1965 Indianapolis '500' Stark Wetzel Rookie ntawm Xyoo.
Thaum xyoo 1960 thiab thaum ntxov 1970s, Dennis Klingman thiab Wyatt Swaim ntawm Lincoln Electric tau mus rau Tebchaws Europe los qhia Formula One auto manufacturers yuav ua li cas TIG weld 4130 raj es tsis txhob brazing.Thaum xyoo 1970s, 4130 yuav maj mam nkag mus rau lwm hom kev sib tw.Nyob ib ncig ntawm 1971, Jerry Weeks Baker tsim lub tawb tshiab siv 4130 ntawm nws lub tsheb Austin Healy Sprite thiab sib tw hauv SCCA lees paub cov xwm txheej.Thaum lub sij hawm ntawd, SCCA phau ntawv txoj cai tau tso cai siv 4130, tab sis nws tsis pom zoo vim tias vuam nyuaj.Jerry tom qab ntawd tsim lub 4130 mini tsheb rau Don Edmonds los koom rau hauv kev sib tw uas tau lees paub los ntawm American Automobile Association (USAC).Nyob ib ncig ntawm 1975, USAC tau hais tias 4130 tuaj yeem siv tau ntev npaum li nws nyob hauv lub xeev qub.
