4130 giredhi remumba 30CrMo isimbi ine alloy ine chromium uye molybdenum, ine simba rekusimba kazhinji pamusoro pe750MPa.Anonyanya kuonekwa pamusika mabhawa uye ndiro dzakakora.Mudhuri wakatetepa 4130 pombi yesimbi ichashandiswa kugadzira Bicycle furemu,.Iyi isangano resimbi rinobviswa pombi.Yakagadzirwa neinotonhora inodhonzwa isina musono kabhoni simbi mapaipi akabhenda uye akaiswa imwe neimwe zvinoenderana neiyo contour yemukati mengoro.Kana iwe ukabvisa ganda remuviri, uchaona keji yesimbi yakagadzirwa nemapombi akawanda esimbi.Naizvozvo, vanhu veHongkongers vanoidana zvakare "roll cage".Nechipfeko chedhaimani chakakosha ichi, kunyangwe mota ikakunguruka kakati wandei uye kunze kwemotokari kusingatsungirike, vamhanyi vari mukati vachange vakachengeteka uye vakanaka.Iyo simbi pombi zvinhu uye twist kuramba inoshandiswa kune anti roll furemu inotemerwa nehuremu hwemuviri wemotokari, uye kazhinji inoda kukwanisa kumirisana nekanopfuura kaviri huremu hwemuviri wemotokari.Sezvo nzira yemujaho wenjanji yakati sandarara, panenge pasisina gwanza.Kusiyana neizvi, kana Rallying mumugwagwa wegomo uye mujaho wekuyambuka-musango mukupidigura, kukuvara kwemuviri kuchave kwakanyanya.Naizvozvo, kusimba kweiyo roll cage ye rally racing uye kuyambuka-nyika mujaho wakakwira, uye chimiro chepombi fittings chakanyanya.Iyo yehunyanzvi yakaiswa anti roll furemu haingogone chete nemamiriro asingatarisirwe, asi zvakare inosimudzira simba uye anti twist yemuviri wemotokari.Semuyenzaniso, nekubatanidza nzvimbo dzakati wandei dzekugezesa dzegororo kumberi nekumashure zvigaro zvekuvhunduka, kunyangwe mota ichigara ichisvetuka, chikamu chesimba rinobva pasi rinozoparadzirwa pane roll cage, iyo inopa dziviriro kune muviri wemotokari.
4130 yainyanya kushandiswa muindasitiri yendege, asi mukutanga kusvika pakati pemakore ekuma1950, payakapinda mujaho chasisi, mamiriro akatanga kuchinja.Kungofanana neindasitiri yendege, kushandiswa kwe4130 seyakanyanya chassis zvimiro zvemujaho kwakagadziridzwa zvishoma nezvishoma mumakore.Panguva iyoyo, mutyairi weRacing vazhinji vakabvunza kugona kwe4130 welding, nekuti TIG welding tekinoroji nyowani, uye vagadziri vazhinji vanoshandisa brazing kuti weld iyi.Yakanga isiri kusvika 1953 iyo Boeing Ndege Kambani yakarekodha ndokutanga TIG welding yayo 4130 chimiro.Izvo hazvigoneke kuona chassis yemotokari yekutanga 4130, asi zvingangoita kuti yakatanga kushandiswa mujaho remota, senge SCCA mota, yepamusoro peturu mota, IndyCar kana Formula One.
Pakazosvika pakati pemakore ekuma1950, motokari dzakawanda dzakagadzirwa ne4130 dzaikwikwidzana mumakwikwi akawanda emakwikwi anozivikanwa neSCCA.Muna 1953, Forest Edwards yakagadzira Edwards / Blue Speical vachishandisa yakaora 51 gore Morris sedan uye 4130. Charles Hall achatyaira "mucheri muduku" wake kuti akunde SCCA H-class yakagadziridzwa Pacific Coast Championship, iyo inoshandisa 1.25 inches × A trapezoidal frame yakagadzirwa ne0.030 inch 4130.
Dragmaster Dart: Dodd Martin naJim Nelson, pamwe chete neDragmaster Dart yavo, vakavamba Dragmaster Company muCarlsbad, California munenge muna 1959 kana 1960. Ivo vari pamberi pehunyanzvi hwekuita zvemijaho uye vakahwina “Best Design” mumakwikwi enyika eNHRA.Mukati isingasviki gore rekuvhurwa, Dragmaster yakatanga kugadzira chassis inonzi "Dart", iyo inouya muzvinhu zviviri: 4130 nesimbi yakapfava.
Muna 1965, iyo Brawner Hawk, injini yekumashure yakagadzirwa kubva ku4130, yakaita debut yayo uye yakatyairwa naMario Andretti.Brawner Hawk akavakwa neane mukurumbira mechanic Clint Browner uye mudzidzi wake Jim McKee panguva iyoyo.Yakagadzirwa yakavakirwa paCopper Climax, mota yekutanga yekumashure kupinda mumutsara wemamaira mazana mashanu muIndia muna 1961, ichityairwa nekaviri Formula One shasha Jack Brabham.Gore iroro, pasi pekutyaira kwaMario, Braun Hawk akawana kubudirira kukuru.PaHusserl Grand Prix yakaitirwa kuIndianapolis Circuit Park, Mario akahwina nzvimbo shanu dzekutanga mumakwikwi mana anokodzera, nzvimbo imwe yedanda nenzvimbo shanu dzepamusoro, pamwe nekukunda kwake kwekutanga muUSAC.Akahwina zvakare mukwikwidzi we1965 mwaka weUSAC uye 1965 Indianapolis '500'Stark Wetzel Rookie yeGore.
Mukupera kwema1960 nekutanga 1970s, Dennis Klingman naWyatt Swaim veLincoln Electric vakaenda kuEurope kunodzidzisa vagadziri veFormula One auto maitirwo eTIG weld 4130 machubhu pane kubhuroka.Mukupera kwema1970, 4130 ichapinda zvishoma nezvishoma mamwe marudzi emakwikwi.Muna 1971, Jerry Weeks Baker akagadzira keji nyowani achishandisa 4130 pamota yake yeAustin Healy Sprite uye akakwikwidza muSCCA zvinozivikanwa zviitiko.Panguva iyoyo, bhuku rekutonga reSCCA raibvumira kushandiswa kwe4130, asi haina kukurudzirwa nekuti welding yaive yakaoma.Jerry akazovaka 4130 mini mota yekuti Don Edmonds atore chikamu mumujaho unocherechedzwa neAmerican Automobile Association (USAC).Kunenge muna 1975, USAC yakataura kuti 4130 inogona kushandiswa chero yakange iri mumamiriro ezvinhu.
Pakazosvika makore ekuma1970, masangano mazhinji ezvitupa akatanga kuda kushandiswa kwe4130 yakagadzirwa roll cage padanho repamusoro remakwikwi.Musi waZvita 12, 1978, SFI yakataura kuti chassis yese yepamusoro-soro yemotokari inofanira kugadzirwa nezvinhu 4130.SFI isangano risingaite purofiti rakanangana nekutsikisa uye kutonga zviyero zvehunyanzvi / kuita mota nemidziyo yemujaho.Pakazosvika 1984, SFI yakataurawo kuti mota dzinosetsa dzinofanirwa kugadzirwa ne4130.
