Heesaha ugu dambeeya ee shaqada muusiga ee guuleysta waa inay ahaadaan kuwo gaar ah. Iyo sida halabuure kasta oo caan ah, BMW si fiican ayey u taqaan sababta oo ah wax la mid ah ayaa run u ah baabuurta, taas oo ah mid ka mid ah sababaha soo ifbaxa BMW M2 CS.
Haddii wax soo saarka moodelku uu ku dhammaado nooc dhexdhexaad ah, taasi waa wax u noqda sida ugu dheggan xusuusta wadajirka ah sida cayayaanka muraayadda hore ee dhammaadka safarka fasaxa xagaaga.
BMW M2 CS ayaa sidaas darteed calaamad u ah dhamaadka 2 Taxanaha (sanad gudihiis ayaa soo baxaya jiilka cusub). Haddii aad xasuusato, tani hadda waxay leedahay qayb weyn oo ka mid ah noocyada ay u adeegto mashiinka hore ee wheel hore, si kastaba ha ahaatee, shaqadan jireed waxay ku sii adkaysatay mabaadi'da calaamadda Bavarian, kuwaas oo baabuurta isboortiga leh dabeecadda heerka ay tahay inay noqdaan. lagu riixo taayirrada danbe oo aan la jiidin taayirrada hore.
nooc aan hore loo arag
Xitaa iyada oo la tixgelinayo in uu jiro tartanka M2 (kaas oo isticmaalaya matoor isku mid ah, laakiin leh 40 hp ka yar laakiin 550 Nm isku mid ah), injineerada Jarmalku waxay rabeen inay kor u qaadaan bararka xitaa in ka badan.

Haddaba, sida Markus Schroeder, oo ah maamulaha mashruucan uu inoo sharxayo, waa markii ugu horreysay oo taxane xaddidan oo nooca BMW-ga ah uu dhasho (waxaa markii hore laga hadlay 75 unug balse waxaa suurtagal ah in ay ka sii gudubto). taas, iyada oo ku xidhan sida ay rabaan inay hadda uga falceliyaan bilawgeeda).
Sida laga soo xigtay Schroeder, "M2 CS waxay sii kordhinaysaa baqshadda firfircoon ee uu soo jeediyay tartanka M2 si uu uga farxiyo nooc aad dhif u ah laakiin aad u baahan nooc macmiil ah oo jecel inuu galo xilli-goobeedka jidka".
Si kale haddii loo dhigo, si gaar ah, oo ah meesha ka saarista tobnaad ee ilbiriqsigiiba si aan kala go 'lahayn loo raadiyo sidii ay tahay Grail Quduuska ah, sidaas darteed caqli-gal ah in kirishbooyada caadiga ah, oo aan ka tagin daamuryada dadweynaha, ay adag tahay in la helo. Awood in la garto waa la qiimeeyaa..
"Waxa aan kuu rabo" fiber carbon
Waa, markaa, CS-ga ugu horreeya ee M2 (waxaa jiray CS ee M3 iyo M4) waxayna u adeegtaa aasaaska gaariga tartanka BMW, wax aan ku adkeynin in la rumaysto riwaayadaha la xoojiyay ee xariiqyada iyo qaybaha.
Aan ku bilowno shaqada jireed ee BMW M2 CS: dibinta hoose ee bambarka hore, bonnet (taas oo miisaankeedu yahay kala badh inta tartanka oo ay ku jirto hawo cusub) iyo aerodynamic profile (Gurney) oo ka soo baxa daboolka shandadu waa cusub tahay.
Fiber Carbon waa meel walba.
Sida faafiyaha ka hooseeya bambarka dambe, dhammaan walxahan waxay ka samaysan yihiin fiber-carbon, dhammaan xaaladaha, walxaha ultra-light iyo ultra-adag ayaa loo soo bandhigay heer ka sii weyn ama ka yar.
Ujeedada walxahan waa in la kordhiyo cadaadiska aerodynamic iyo hawada channel hawada agagaarka iyo hoos baabuurka, la yareeyo qaska.
Isticmaalka fiber kaarboonka waxaa sabab u ahaa rabitaanka dhimista miisaanka. Waxa xiisaha lihi leh, M2 CS waxa uu miisaan ka yara yar yahay Tartanka ("in ka yar 40kg", sida uu qabo Schroeder) oo dhan 1550 kg.
Qiimo la taaban karo, ugu yaraan sababtoo ah ka joojinta la qabsiga waxay kordhisaa miisaanka marka la barbar dhigo " dadban" ee kala duwanaanta walaal. Dhammaan sababtoo ah BMW waxay dooratay inaysan samayn baabuur xad dhaaf ah.
Haddii ay taasi ahaan lahayd ujeedada koowaad, way sahlanaan lahayd in la sameeyo la'aanteed kuraasta danbe, qaboojiyaha ama habka maqalka. Sidaa darteed, kororka qaybaha fiber-carbon iyo hoos u dhigida qalabka dahaarka ee acoustic kuma filna "cunto" aad u adag.
Matoorka ku habboon
Iyada oo leh lix dhululubo oo khadka-line ah, 3.0 l iyo (halkan) 450 hp, mishiinkani wuxuu ku qalabaysan yahay injineernimada BMW ugu fiican: laga bilaabo labada turbo mono-croll, cirbadeynta tooska ah ee saxda ah ee saxda ah, nidaamka isbeddelka valve (Valvetronic). ) ama Vanos crankshaft (guditaanka iyo qiiqa), ma jiraan wax maqan.
Weli, dhimista xishoodka ee miisaanka waxay la macno tahay in BMW M2 CS aanu wax badan ka qabanayn tartanka M2 ee xoogaa ka awood yar xagga waxqabadka.
Taasi waxay tidhi, iyada oo leh sanduuqa gear-ga ee lixda-xawaaraha ah (ka hore ee BMW oo leh naaneyska CS) 100 km/h wuxuu ku yimaadaa 4.2 s, si kale haddii loo dhigo, rikoodh la mid ah tartanka gudbinta tooska ah ee labajibbaaran M DCT .
Marka lagu rakibo sanduuqan gear-ga, BMW M2 CS waxay arkaysaa wakhtiga 0 ilaa 100 km/saacaddii hoos u dhac ku yimi 2 tobnaad ee ilbiriqsi iyo isticmaalku wuu soo hagaagayaa. Dhibaatada? Doorashada waxay ku miisaamaysaa 4040 euro miisaaniyadii horeba u dalbanaysay…
Xawaraha ugu badan, tani waa 280 km/h (10 km/h in ka badan tartanka).
Chassis wuu isbedelaa in ka badan injiinka
Waxa xiisaha lihi leh, ma ahayn mishiinkii wax ka beddelay M2 CS, iyada oo warka ugu weyn loo qoondeeyay shasis-ka iyo isku xirka dhulka.
Dhanka biriiga, biriiga M Compound waxay isticmaashaa saxanooyin ka waaweyn dhamaan afarta taayir (xitaa waxay noqon karaan karbon-seramik).
Ka joojinta, waxaan ku haynaa qaybo fiber carbon ah xagga hore (marka lagu daro aluminium, kaas oo sidoo kale loo isticmaalo dhabarka), baadiyaha ayaa aad u adag oo mar kasta oo ay suurtogal tahay (iyo faa'iido leh) injineerada ayaa dalbaday xiriiro adag (caag la'aan). Hadafka? Hagaajinta hagida giraangiraha iyo xasiloonida jihada.
Weli in berrinkii ganaax, waxaan haynaa ugu horeysay: markii ugu horeysay M2 uu leeyahay la qabsiga caadiga ah shoogga elektaroonigga ah (oo leh saddex nooc: Raaxada, Sportiga iyo Sport+).
Sidaa darteed, ka joojinta la doonayo in lagu adkeeyo wareegga kama dhigayso wadista waddooyinka dadweynaha dhibaato raaxo darro ah.
Isla mar ahaantaana waxaa suurtagal ah in la beddelo miisaanka isteerinka (kaas oo xitaa habka Raaxada had iyo jeer aad u culus), jawaabta qalabka (otomaatig ah), jawaabta barnaamijka xasilloonida, jawaabta iyo codka matoorka. (sidoo kale lagu bedeli karo badhan ku yaal konsole dhexe).
Sida caadiga ah tartanka M2 waxaan leenahay M Active differential, auto-blocking iyo M Dynamic Mode, hawl-hoosaad ka mid ah nidaamka xakamaynta xasiloonida kaas oo u oggolaanaya heer aad u sarreeya oo simbiriirixan ah.
Dhanka is-xakamaynta, marka ay ogaato khasaaraha ugu yar ee dhaqdhaqaaqa waxay si buuxda u kala duwanaan kartaa gudbinta qulqulka ee u dhexeeya labada taayir ee dambe (100-0 / 0-100), heerka ugu habboon ee xannibaadda ayaa markaa lagu qeexaa oo lagu dabaqaa matoor. koronto ku jirta 150 millise seconds.
Aad faa'iido u leh si lama filaan ah ugu bilaabo dusha sare leh heerar kala duwan oo xajin ah, auto qufulka kaliya ma caawinayo in gaariga la jiido qalooca (la dagaalanka isteerinka hoostiisa marka la galayo qalooca ugu adag ee lagu sameeyay xawaare sare) laakiin sidoo kale wuxuu dejiyaa marka degdega ah ee la joogo waxay noo sheegaysaa in ay fiican tahay in la joojiyo oo la leexiyo isku mar.
Michelin Pilot Cup taayirrada (245/35 xagga hore iyo 265/35 xagga dambe, 19 "taayirrada ee muraayadaha madow ee caadiga ah ama dahab caajis ah sida ikhtiyaarka) ayaa ah kuwa ugu habboon kuwa ku fekeraya inay waqtigooda inta badan ku qaataan CS. wadada ku socota.
Haddii fikradda ay tahay kaliya in la helo isboorti isboorti oo aad u cajiib ah oo loogu talagalay qaar ka mid ah fuulitaanka socodka gaabiska ee wadada (laga yaabee horeba uga fakarayay qaddarinta mustaqbalka ee baabuur leh wax kasta oo awood u leh inuu noqdo ururin), markaa Super ugu habboon Taayirada isboortiga (kaliya sheeg, bilaash, markaad dalbanayso).
Waddada loo maro kala duwanaanshaha
Ka dib markii la sameeyay bandhigyada lagama maarmaanka ah ee BMW M2 CS, ma jiraan wax la mid ah in lagu socodsiiyo wareegga (xaaladdan Sachsenring, Germany) si ay isugu dayaan inay ogaadaan qaar ka mid ah faa'iidooyinka la ballanqaaday.
Ka dib oo dhan, oo leh heerkan waxqabadka, waayo-aragnimada ka dambeysa giraangiraha wadada waxay noqon doontaa wax ka yar iftiiminta, xitaa haddii ay kuu ogolaato inaad fahamto shakhsiyadda ka timaadda qalabka elektarooniga ah ee shoogga.
Badhanka bilawga, onkodka injiinka, cirbadaha nolosha soo baxaya oo halkaas aad tagayso… Ma haboona in la sheego in kani yahay baabuur dheereeya, aad u dheereeya.
0 ilaa 100 km / h waxay xitaa garaacday xafiiltanka ugu weyn "albaabada ka baxsan", aad u qaali ah (qiimaha 138,452 euro) laakiin dhexdhexaad ah oo dheellitiran falcelinta Porsche Cayman GT4.
Farqiga u dhexeeya waa ku dhawaad nus ilbiriqsi, ka dibna Cayman oo leh feerka lix-dhululubo, 4.0 l, atmospheric 420 hp oo ah xawaaraha ugu sarreeya ee gaaraya 304 km / h marka la barbardhigo 280 km / h ee M2 CS.
Tani waxay inta badan sabab u tahay aerodynamics la safeeyey iyo miisaan hoose (qiyaastii 130 kg ka yar), taas oo ugu dambeyntii u oggolaanaysa inay ku faanto miisaan / awood yar oo aad u wanaagsan (3.47 kg / hp ee Porsche iyo 3.61 ee BMW) oo sidaas darteed magdhow awoodda hoose iyo maqnaanshaha turbo.
Chassis dhalaalaya
Iyadoo la tixgelinayo isbeddellada badan ee isku-xirnaanta iyo isku-xirnaanta dhulka iyo sifooyinkooda asaasiga ah, maahan wax la yaab leh, xitaa qarka u saaran "dib u habeyn", M2 CS waxay ku faani kartaa chassis dhalaalaya.
Dhab ahaantii, waa xitaa mid ka mid ah BMW-yada ugu waxtarka badan ee ku jira jidka waligiis, taas oo aan ahayn wax yar marka loo eego qiyaasta sare ee calaamadda Bavarian ee arrintan la xiriira.
Wadooyinka qalalan, waxaa la dhihi lahaa in baabuurka hore uu ku dhejiyay dhulka iyo in uu yahay kan dambe ee xaaqaya jidka, oo leh dhaqdhaqaaq yar ama ka yar, taas oo ku xidhan habka xakamaynta xasiloonida ee la doortay.
Laakin, haddii qabsashadu ay ka yar tahay mid wanaagsan ama haddii asphalt-ku qoyan yahay, gadaasha M2 CS waxay u egtahay inay rabto inay hesho rabitaan u gaar ah, oo had iyo jeer maaha marka ay timaado taas.
Xaaladahan, waxay noqon doontaa mid la doorbidi karo in la sameeyo dhabannada jidka "hal gacan oo hoose", taas oo macnaheedu yahay, xakamaynta xasilloonida ee barnaamijka ugu jilicsan.
Marka laga hadlayo waxqabadka matoorka, dib u dhaca jawaabta turbo waa mid aad u yar iyo xaqiiqda ah in ay keento dhammaan qulqulka dhulka taagga ah laga bilaabo 2350 ilaa 5500 rpm ayaa muhiim u ah dhululubada inay had iyo jeer “buuxaan”, gaar ahaan mashiinka turbo.
In kasta oo ay jiraan fiber kaarboon oo badan, badbaadinta miisaanka marka loo eego Tartanka M2 waa 40 kg oo keliya.
Cutubka gudbinta, oo leh sanduuqa gearbox-ka waxaa jira shaqaale badan (iyo "ka-qaybgal" badan oo daahiriyayaal ah ayaa odhan doona).
Isteerinka laba-xajin ee todobada qaybood, waxaa jira feejignaan dheeraad ah oo loogu talagalay dhabbaha halka gearsyadu ay ka duulayaan kor ilaa hoos iyagoo wata suufka ka dambeeya isteerinka waxaadna badbaadin kartaa dhowr ilbiriqsi halkiiba.
Jiirarrada, qaybinta miisaanka le'eg ee ka sarreeya labada geesood iyo adkaanta sii kordhaysa ee shasis/shaqada jirku waxay ka dhigaysaa BMW M2 CS mid wareeg ah oo u leexanaysa iyada oo la hubo in skier shahaado leh.
Tani waa inkasta oo qaar ka mid ah qalooca degdega ah u janjeera in la kordhiyo jihada la dareemayo, taas oo injineerada Jarmalku ay yiraahdaan waa ula kac sababtoo ah waxay ka caawisaa in la fahmo halka ay xaddidan tahay.
Xaddidaadahan ayaa sidoo kale aad u fog sababtoo ah la qabsiga la qabsiga ee xakameynta liiska jirka iyo adkeynta hakinta haddii aan dooranno qaabka Sport +.
Si kastaba ha ahaatee, xaaladaas waxaa laga yaabaa in lagugula taliyo in la doorto barnaamij dhexdhexaad ah isteerinka, kaas oo dareemaya culeys aad u culus - laakiin aad u sax ah, iyada oo ay ugu wacan tahay kororka yar ee qashin-gacmeedka.
Maaddaama ay jiraan laba badhan oo M Mode ah oo ku yaal isteerinka, waxaad u dejin kartaa goobaha aad doorbidayso
gearbox/engine/steering/hakinta/ xakamaynta jiidista oo hel midka aad ugu jeceshahay.
Fikradda waa in la helo mid leh goobaha la doorbido ee wadada iyo kan kale ee wadada, sidaas darteed waqti badbaadiya.
Goorma ayay imanaysaa iyo qiimaheedu?
Iyada oo tirada unugyada la dhisayo ay tahay su'aal furan, laba shay ayaa durba la hubaa oo ku saabsan BMW M2 CS.Midda koowaad waa in ay suuqa soo gashay bishan, tan labaadna waa in nooca gacanta lagu gudbiyo uu ku kacayo 116 500 oo Yuuro, kala duwanaanshaha gudbinta tooska ahna waa 120 504 Yuuro.
