E like me nā koi o nā lula ma ke kiʻi, ʻo ke ʻano o ke kaʻa heihei e hoʻokomo i ʻelua pahu ʻōwili me ke kākoʻo, ke poʻo mua me ka ʻōnaehana kākoʻo a me ka ʻōnaehana pale, a me ka ʻaoʻao anti-collision structure, ʻo ia hoʻi, ke apo nui, ke apo mua. , Kākoʻo hili o ka hale ʻōwili a me kona ʻano kākoʻo, ʻaoʻao anti-collision structure, front bulkhead, and front bulkhead support system.Hiki i nā ʻāpana kiʻi āpau ke hoʻoili i ka ukana o ka ʻōnaehana hoʻokele kaʻa i ke ʻano kumu.ʻO ka ʻāpana kiʻi e pili ana i ka pōkole pōkole loa, ʻaʻole i ʻoki ʻia, a me ka hoʻomau ʻana i nā paipu paipu pākahi.ʻO kekahi o nā hana o ka pahu ke kū i nā ukana like ʻole mai loko a ma waho o ke kaʻa, akā ʻokoʻa nā ʻano mechanical o nā mea like ʻole, he mea paʻakikī i nā mea hoʻolālā a me nā luna kānāwai e hoʻoholo inā e kūpono ana ka nui o ka ukana i nā kūlana.ʻO ke kila kila he hao kalapona hao i hana ʻia ma ka hoʻohui ʻana i ka nui kūpono o hoʻokahi a ʻoi aku paha nā mea hoʻohui i ke kila kalapona maʻamau.Ma ka hoʻohuiʻana i nā mea likeʻole a me ka hoʻohanaʻana i nāʻano hana hana likeʻole, nā waiwai kūikawā e like me ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, ke kū'ēʻana i kaʻaʻahu, ka paleʻana i ka corrosion, ka haʻahaʻa haʻahaʻa haʻahaʻa, ke kiʻekiʻe o ka mahana wela, aʻaʻole hiki ke loaʻa ka magnetism.A ʻo ka inoa piha o kā mākou protagonist ʻo 30CrMo Pipe, i ʻike ʻia ʻo 4130 Steel Pipe.He kiʻekiʻe ka ikaika a me ka paʻakikī, ka hardenability maikaʻi, a me ke anawaena hardenability o 15-70mm i ka aila.ʻO ke kila ka ikaika wela maikaʻi, mai ka 500 ˚ Ma lalo o C, loaʻa iā ia ka ikaika kiʻekiʻe-mehana a me ka hana hoʻoheheʻe maikaʻi.
ʻO 4130 home grade 30CrMo he kila kila i loaʻa ka chromium a me ka molybdenum, me ka ikaika tensile ma luna o 750MPa.ʻO ka mea i ʻike pinepine ʻia ma ka mākeke ʻo nā kaola a me nā papa mānoanoa.E hoʻohana ʻia ka paipu kila 4130 i hoʻopaʻa ʻia no ka hana ʻana i ka paikikala,.He hui paipu kila hiki ke wehe.Hana ʻia ʻo ia me nā paipu kila carbon seamless i huki ʻia a hoʻokomo ʻia i kēlā me kēia e like me ka contour o loko o ke kaʻa.Inā wehe ʻoe i ka pūpū kino, e ʻike ʻoe i kahi hale hao i hana ʻia me nā paipu kila.No laila, kapa ʻia e ka poʻe Hong Kong he "roll cage".Me kēia kapa kila daimana makamae, ʻoiai ke kaʻa kaʻa i kekahi mau manawa a ʻaʻole hiki ke ʻae ʻia ka waho o ke kaʻa, e palekana a kani ka poʻe heihei i loko.Hoʻoholo ʻia ka mea paipu kila a me ke kūpaʻa wili i hoʻohana ʻia no ka ʻōwili anti roll e ke kaumaha o ke kino o ke kaʻa, a maʻamau pono e hiki ke pale i ka hopena o ʻoi aku ma mua o ka pālua o ke kaumaha o ke kino kaʻa.No ka mea, he palahalaha ka ili alanui o ka heihei heihei, aneane aohe kaawale.ʻO ka ʻokoʻa, inā huli ka Rallying ma ke alanui mauna a me ka heihei kea i ka nahele hihiu, ʻoi aku ka nui o ka pōʻino o ke kino.No laila, ʻoi aku ka kiʻekiʻe o ka ikaika o ka hale ʻōwili no ka heihei rally a me ka heihei cross-country, a ʻoi aku ka paʻakikī o ke ʻano o nā paipu paipu.ʻAʻole hiki i ka ʻoihana anti roll frame ke hoʻokō wale i nā kūlana i manaʻo ʻole ʻia, akā hoʻonui pū i ka ikaika a me ka anti twist o ke kino kaʻa.No ka laʻana, ma ka hoʻohui ʻana i kekahi mau kūlana kuʻi ʻia o ka hale ʻōwili i nā noho hoʻoheheʻe haʻalulu i mua a ma hope, ʻoiai inā lele pinepine ka kaʻa, e hoʻopuehu ʻia kahi ʻāpana o ka hopena mai ka lepo ma luna o ka hale ʻōwili, kahi e pale ai i ka kino kaʻa.
Ua hoʻohana nui ʻia ʻo 4130 i ka ʻoihana mokulele, akā i ka hoʻomaka ʻana o ka makahiki 1950, i kona komo ʻana i ka hoʻolālā chassis heihei, ua hoʻomaka ke kūlana.E like me ka ʻoihana mokulele, ua hoʻomohala ʻia ka hoʻohana ʻana o 4130 ma ke ʻano he chassis structural material i ka heihei i nā makahiki.I kēlā manawa, nui nā mea hoʻokele kaʻa i nīnau i ka hiki wili o 4130, no ka mea, he ʻenehana hou loa ka welding TIG, a ʻo ka hapa nui o nā mea hana e hoʻohana i ka brazing e weld i kēia mea.ʻAʻole a hiki i ka makahiki 1953 i hoʻopaʻa ʻia ʻo Boeing Aircraft Company a hoʻomaka i ka hoʻopili ʻana o TIG i kāna ʻano 4130.ʻAʻole hiki ke hoʻoholo i ka chassis o ke kaʻa mua 4130, akā ua hoʻohana mua ʻia ia i ka heihei kaʻa, e like me SCCA kaʻa, kaʻa wahie kiʻekiʻe, IndyCar a i ʻole Formula One.
Ma ka waena o 1950s, nui nā kaʻa i hana ʻia me 4130 e hoʻokūkū ana i nā pae he nui o ka hoʻokūkū i ʻike ʻia e SCCA.I ka makahiki 1953, ua hana ʻo Forest Edwards i ka Edwards/Blue Speical me ka hoʻohana ʻana i kahi sedan 51 makahiki Morris a me 4130. E hoʻokele ʻo Charles Hall i kāna "little excavator" e lanakila ai i ka SCCA H-class modified Pacific Coast Championship, e hoʻohana ana i ka 1.25 inches × A trapezoidal frame hana ʻia me 0.030 iniha 4130.
Dragmaster Dart: Ua hoʻokumu ʻo Dodd Martin lāua ʻo Jim Nelson, me kā lāua Dragmaster Dart, i ka Hui Dragmaster ma Carlsbad, Kaleponi ma kahi o 1959 a i ʻole 1960. Aia lāua ma ke alo o ka ʻenehana heihei a ua lanakila lākou i ka "Best Design" i ka hoʻokūkū aupuni NHRA.I loko o hoʻokahi makahiki o ka wehe ʻana, ua hoʻomaka ʻo Dragmaster e hana i kahi chassis i kapa ʻia ʻo "Dart", e hele mai ana i ʻelua mau mea: 4130 a me ke kila māmā.
I ka makahiki 1965, ua hoʻomaka ka Brawner Hawk, he ʻenekini hope i hana ʻia mai 4130, a ua alakaʻi ʻia e Mario Andretti.Ua kūkulu ʻia ʻo Brawner Hawk e ka mīkini kaʻao Clint Browner a me kāna haumāna ʻo Jim McKee i kēlā manawa.Ua hoʻolālā ʻia ma muli o Copper Climax, ke kaʻa ʻenekini hope mua e komo i ka laina hoʻomaka 500 mile ma India i ka makahiki 1961, i alakaʻi ʻia e ʻelua manawa Formula One champion Jack Brabham.I kēlā makahiki, ma lalo o ke kaʻa ʻana o Mario, ua lanakila ʻo Braun Hawk.Ma ka Husserl Grand Prix i mālama ʻia ma Indianapolis Circuit Park, ua lanakila ʻo Mario i nā wahi ʻelima mua i nā hoʻokūkū hoʻokūkū ʻehā, hoʻokahi kūlana pole a ʻelima mau wahi kiʻekiʻe, a me kāna lanakila mua ma USAC.Ua lanakila 'o ia i ka ho'okûkû makahiki 1965 o USAC a me ka 1965 Indianapolis '500' Stark Wetzel Rookie o ka Makahiki.
I ka hopena o nā makahiki 1960 a me nā makahiki 1970, ua hele ʻo Dennis Klingman lāua ʻo Wyatt Swaim o Lincoln Electric i ʻEulopa e aʻo i nā mea hana kaʻa Formula One pehea e TIG weld 4130 paipu ma kahi o ka brazing.I ka hopena o nā makahiki 1970, e komo mālie ʻo 4130 i nā ʻano hoʻokūkū ʻē aʻe.Ma kahi o 1971, ua hana ʻo Jerry Weeks Baker i hale paʻa hou me ka hoʻohana ʻana i ka 4130 ma kāna kaʻa Austin Healy Sprite a hoʻokūkū i nā hanana i ʻike ʻia e SCCA.I kēlā manawa, ua ʻae ka puke kānāwai o SCCA i ka hoʻohana ʻana iā 4130, akā ʻaʻole ia i ʻōlelo ʻia no ka paʻakikī o ka wili.Ua kūkulu ʻo Jerry i kaʻa liʻiliʻi 4130 no Don Edmonds e komo i ka heihei i ʻike ʻia e ka American Automobile Association (USAC).Ma kahi o 1975, ua ʻōlelo ʻo USAC e hiki ke hoʻohana ʻia ʻo 4130 inā lōʻihi ia ma kahi kūlana maʻamau.
Ma ka hopena o nā makahiki 1970, ua hoʻomaka ka nui o nā keʻena hōʻoia e koi i ka hoʻohana ʻana i ka 4130 i hana ʻia i ka hale ʻōwili i ka pae kiʻekiʻe o ka hoʻokūkū.Ma ka lā 12 o Dekemaba, 1978, ua ʻōlelo ʻo SFI e pono e hana ʻia nā chassis kaʻa wahie kiʻekiʻe o 4130.He hui waiwai ʻole ʻo SFI i manaʻo ʻia e paʻi a hoʻokele i nā kūlana no ka ʻoihana kaʻa a me nā lako heihei.Ma ka makahiki 1984, ua ʻōlelo pū ʻo SFI e pono e hana ʻia nā kaʻa ʻakaʻaka me 4130.
