KTM EXC / SX, chaka chachitsanzo 2008
Zamkatimu
Kukumbukira chiyambi cha mndandanda wa EXC womwe unkalamulira dziko la enduro, palibe chifukwa choyang'ana mmbuyo. Zinali 1999 pomwe KTM idabweretsa chida chatsopano cha njinga zamoto za enduro ndi motocross ndi Husaberg yomwe yangogulidwa kumene. Lero, aliyense wokonda motorsport amadziwa bwino za utoto wa lalanje.
Koma nthawi zikusintha, ndipo ndi iwo (makamaka) zofunikira zachilengedwe. Chipinda chakale komanso choyesera-chenicheni chinayenera kutsanzikana ndipo XC4 yatsopano tsopano ikukwaniritsa miyezo ya Euro3 ndi pulogalamu yotulutsa yomwe imakhalanso ndi chosinthira chothandizira.
Pambuyo pa mzere wokonzanso wa motocross chaka chatha komanso injini yatsopano ya mitundu ya SX-F yokhala ndi ma camshafts awiri, funso lodziwika kwambiri linali loti KTM ikhoza kungokwanira utsi wodekha komanso zida zofunikira za enduro (magetsi akutsogolo ndi kumbuyo). masanjidwe omwe alipo a motocross., mita ...). Koma sizinachitike.
Mitundu yamotocross ndi enduro tsopano imagawana chimango, zigawo zina zapulasitiki ndi swingarm, ndipo ndizomwezo. Injini tsopano ikupezeka mumitundu iwiri yokha - 449 cc. CM yokhala ndi 3x63mm ndi 4cc. Onani kuchokera 95 × 510 mm. Onse analengedwa ndi kupangidwa kokha kwa zosowa za okwera enduro.
Pamutu pa unit yatsopano pali camshaft imodzi yokha yokhala ndi mavavu anayi a titaniyamu, yomwe imachepetsa kukwiya kofunikira kwa motocross. Mutu wamphamvu womwewo umakhalanso ndi chodulira chatsopano cha oblique kuti ufikire mwachangu komanso kusintha kosavuta kwa valavu. Palinso kusiyana mu kutsinde waukulu, kondomu ndi HIV. Shaftyo imalemera chifukwa chofunikanso kumenyera kumbuyo pa gudumu lakumbuyo (inertia), koma sanaiwale za chitonthozo ndikuwonjezera kutsinde kolemetsa kuti muchepetse kugwedezeka. Mafuta a gearbox ndi silinda ndi ofanana, koma muzipinda ziwiri zosiyana ndi mapampu atatu amasamalira mayendedwe ake. Bokosi lamagetsi limakhala enduro yothamanga isanu ndi umodzi. Chipangizocho chakhala chopepuka theka la kilogalamu.
Zina mwazinthu zinayi zam'magazi a enduro ndi awa: bokosi lalikulu la ndege lomwe limalola kusintha kwa fyuluta ya mpweya (Twin-Air monga muyezo) popanda kugwiritsa ntchito zida, thanki yatsopano yamafuta abwino. mawondo ndi kapu yamafuta a bayonet (komanso pamitundu ya SX), grille yakutsogolo yokhala ndi magetsi oyatsa ndiyopepuka, yolimbana kwambiri ndi zokopa ndi zovuta zake ndipo ikugwirizana ndi malangizo amapangidwe anyumba, zotetezera kumbuyo ndi mapanelo am'mbali amawonetsedwa kumapeto Mu zitsanzo za SX za chaka chatha, taillight (Ma LED) ang'onoang'ono, atsopano komanso ozizira am'mbali okhala ndi zithunzi ndizopepuka, dongosolo lotulutsa utsi molingana ndi muyezo wa EURO III lili ndi kapangidwe kamakono kwambiri, gawo latsopanolo ndilatsopano, kuzizirako kumakhala kosavuta motero sikunenepa pang'ono, ma disc a EXCEL ndi opepuka.
Chinanso chatsopano ndi kudodometsedwa kwakumbuyo kwa PDS komwe kuli ma millimeter khumi oyenda komanso kukhotakhota kopitilira muyeso. Swingarm yomwe, ikaphatikizidwa ndi chimango chowulungika cha cromolybdenum oval, chimapereka kukhazikika kofunikira komanso kusinthasintha kuti ntchitoyi ikhale yosavuta. kotero kuti njinga yamoto "imapuma" ndi woyendetsa komanso mtunda.
250cc EXC-F yasinthidwanso pamutu wamiyala ndi poyatsira poyatsira, chifukwa chake kuyankha kwake motsika kwambiri tsopano kuli bwino.
Wolamulira wama stroke awiri asintha pang'ono. Pisitoni mu mitundu ya EXC ndi SX 125 ndiyatsopano, madoko oyamwa adakonzedweratu kuti akhale ndi mphamvu zocheperako, ndipo ma injini onse awiri omwe ali ndi sitiroko amakhalanso ndi ma curve awiri oyendetsa mosiyanasiyana. Zachilendo kwambiri mu EXC 300 ndizoyambira zamagetsi (zosankha pa EXC 250), silinda yatsopanoyo ndi XNUMX kilogalamu yopepuka.
Tawonani kulimba kwamphamvu pa SX-F 450 (kuyenda bwino kwamafuta). M'munda, zatsopano zatsimikizira kuti zili bwino. Tidachita chidwi kwambiri ndi EXC-R 450, yomwe ili yabwinoko kwa kalasi yake kuposa yomwe idamuyambitsa (ndipo iyi sinali yoyipa). Zomwe zimachitikira kuyendetsa galimoto zakhala zosavuta komanso koposa zonse, sitingachitire mwina koma kusilira injini, yomwe ndiyabwino pamikhalidwe ya enduro. Sichitha mphamvu, ngakhale pansi kapena mukakankhira, ndipo nthawi yomweyo, imagwira ntchito ndi makokedwe kotero kuti kukwera motsetsereka komanso kwamiyala yamiyala sikutopetsa kwambiri.
Ergonomics ndi yangwiro ndipo thanki yatsopano yamafuta siyisokoneza njinga yamoto. Mabuleki adagwira ntchito bwino, akadali ndi mphamvu zambiri, ndipo kupita patsogolo kumamveka poyimitsidwa. Kungoyimitsa mphuno pang'ono pakona (kowonekera kwambiri pamayeso amsewu) ndikuyimitsidwa komwe kumalepheretsa driver kuyendetsa mokwanira kwathunthu kunalekanitsa KTM iyi ndi ungwiro.
KTM ikadalibe chidwi kugwedezeka pamtunda wothamanga kwambiri, ndipo kumbuyo kumakhazikika mwamphamvu. Ndizowona, komabe, kuti PDS imagwira ntchito bwino kuposa kachitidwe kakang'ono nthawi zina (makamaka pamchenga ndi malo athyathyathya). Timapezanso mayankho abwino omwe, mwa mzimu wa minimalism, amakwaniritsa bwino cholinga cha mpikisano wa enduro. Mwanjira imeneyi simupeza zopanda pake, zosintha zazikulu kapena zida zosalimba. Ndikufuna kuyamika bar yolimba ya Renthal yopanda mtanda ndi bar yolimba yomwe sinaphwanyike ngakhale tili ovuta komanso tikuponda.
Mchimwene wamkulu yemwe ali ndi dzina la EXC-R 530 ndizovuta kwambiri kuyendetsa ndipo amafunikira woyendetsa wophunzitsidwa bwino, makamaka chifukwa cha kuchuluka kwa anthu osinthasintha. Kupita patsogolo kwapangidwanso ndi EXC-F 250, yomwe, kuphatikiza pa chimango, thupi la pulasitiki ndikuyimitsidwa, yapeza kusinthasintha komanso kuchuluka kwa magwiridwe antchito a injini.
Nkhani yosangalatsa komanso yapadera ndi EXC 300 E, ndiko kuti, kugunda kwawiri ndi choyambira chamagetsi. KTM imakhulupirirabe ndikupanga ma injini a sitiroko awiri (amakumananso ndi miyezo ya EURO III) yomwe ingasangalatse okwera osachita masewera omwe amafunikira kugulidwa komanso kusamalidwa pang'ono, komanso onse ochita monyanyira omwe akufunika kukwera njira zosatheka mosavuta momwe angathere. katundu wochepa. nthawi yomweyo injini yamphamvu. Pano, KTM ili ndi phale lolemera kwambiri lomwe mungasankhe momwe mungakonde ndipo simudzaphonya. Mwa ma EXC okhala ndi injini 200, 250 ndi 300cc, mazana atatu ndi omwe amakonda kwambiri.
Pomaliza, mawu odabwitsa ochokera kubanja la SX la ma modocross. Monga tafotokozera, KTM idatinso injini zama stroke sizinthu zakale, ndichifukwa chake zidakhala zoyambirira kuvumbulutsa injini ya 144cc yama stroke. Onani (SX 144), yomwe iyesa kupikisana ndi ma 250cc ma injini anayi. mayiko ena. Ndi gawo lokulirapo lokhala ndi ma cubic mita a 125, omwe amafunikiratu kuyendetsa kuposa 125 SX, koma alibe kuthekera kwenikweni poyerekeza ndi injini yamaoko anayi mnyumba yomweyo.
Timadabwitsanso ngati othamanga othamanga pa injini yama 250cc yama stroke awiri amatha kutero. Mukuwona kupitiliza injini yamaoko anayi yomwe imasunthira komweko koma akavalo ochepa? Mwina ayi. Pepani. Koma mphekesera zikafalikira zakubwerera kwa injini yama stroke (125cc) ku World Championship (kalasi ya MX2), chiyembekezo chimatsalira, makamaka kwa a motocross ndi achinyamata omwe akufuna kuthamanga. Komanso chifukwa cha KTM, yemwe amamvetsetsa kufunikira kwa ana bwino. Pomaliza, kwa achichepere, ma SX 50, 65 ndi 85 awo ali kale magalimoto othamanga, ofanana ndi magalimoto akuluakuluwa.
