Moteri ya Harley-Davidson Revolution Max 1250 iteranyirizwa mu ruganda rwa Pilgrim Road muri Wisconsin. V-Twin ifite ubushobozi bwo kwimuka bwa cm 1250, umuvuduko wayo ni santimetero 105 x santimetero 72, kandi ishobora gutwara ingufu za horsepower 150 na torque ya lb-ft 94. Torque ntarengwa ni 9500 naho igipimo cyo gukanda ni 13:1.
Mu mateka yayo yose, Harley-Davidson yakoresheje iterambere ry'ikoranabuhanga, yubaha umurage w'ikirango cyayo, kugira ngo itange umusaruro nyawo ku bashoferi nyabo. Kimwe mu byo Harley yagezeho mu buryo bugezweho ni moteri ya Revolution Max 1250, moteri nshya ya V-twin ikonjeshwa n'amazi ikoreshwa muri Pan America 1250 na Pan America 1250 Special models.
Moteri ya Revolution Max 1250 yakozwe mu buryo bworoshye kandi bunoze, ifite umugozi munini w’amashanyarazi wo kongera ingufu. Moteri ya V-Twin yatunganyijwe by’umwihariko kugira ngo itange ingufu zikwiye kuri Pan America 1250, hibandwa cyane ku gutanga imbaraga zoroshye zo mu rwego rwo hasi no kugenzura umuvuduko wo hasi ku modoka zigenda mu muhanda.
Kwibanda ku musaruro no kugabanya ibiro bituma imiterere y’ibinyabiziga na moteri ikorwa, guhitamo ibikoresho no kunoza imiterere y’ibice byabyo. Kugira ngo bigabanye uburemere rusange bwa moto, moteri ishyirwa muri Pan Am model nk'igice cy'ingenzi cya chassis. Gukoresha ibikoresho byoroheje bifasha kugera ku gipimo cyiza cy’imbaraga hagati y’uburemere n’uburemere.
Moteri ya Revolution Max 1250 iteranyirizwa muri Harley-Davidson Pilgrim Road Powertrain Operations muri Wisconsin. V-Twin ifite ubushobozi bwo kwimuka bwa cm 1250, ifite umuvuduko wa cm 105 x cm 72, kandi ifite imbaraga zo gutwara horsepower 150 na torque ya lb-ft 94. Torque ntarengwa ni 9500 naho igipimo cyo gukanda ni 13:1.
Igishushanyo cya moteri ya V-Twin gitanga uburyo bwo kohereza ubutumwa bugufi, gishyira hamwe uburemere kugira ngo kirusheho kuringaniza no gucunga neza, kandi giha umugenzi umwanya uhagije wo kugenda. Inguni ya V-degree 60 y'amasilinda ituma moteri igumana neza mu gihe itanga umwanya wo kumanuka hagati y'amasilinda kugira ngo umwuka unyure neza kandi unoze imikorere.
Kugabanya uburemere bwa transmission bifasha kugabanya uburemere bwa moto, ibyo bikaba byongera imikorere myiza, kwihuta, kuyitwara no kuyifunga. Gukoresha Finite Element Analysis (FEA) n'uburyo bugezweho bwo kunoza imiterere mu cyiciro cyo gushushanya moteri bigabanya uburemere bw'ibikoresho mu bice byabumbwe n'ibibumbano. Urugero, uko igishushanyo cyagendaga gitera imbere, ibikoresho byakuwe mu gikoresho cyo gutangiza no mu gikoresho cyo gutwara camshaft kugira ngo bigabanye uburemere bw'ibi bice. Silindari imwe ya aluminiyumu ifite ubuso bwa nickel-silicon carbide electroplating ni imiterere yoroheje, hamwe n'igifuniko cyoroheje cya magnesium alloy rocker, igifuniko cya camshaft n'igifuniko nyamukuru.
Nk’uko bivugwa na Alex Bozmosky, umuyobozi mukuru wa Harley-Davidson, umuhanga mu by’imodoka witwa Revolution Max 1250, ni igice cy’imiterere ya chassis ya moto. Kubwibyo, moteri ifite imirimo ibiri - gutanga ingufu no kuba igice cy’imiterere ya chassis. Gukuraho imiterere gakondo bigabanya cyane uburemere bwa moto kandi bigatanga chassis ikomeye cyane. Impande z’imbere, iz’imbere n’iz’inyuma zihambiriwe ku cyuma gikwirakwiza umuriro. Abatwara abagenzi bagera ku musaruro mwiza binyuze mu kuzigama ibiro byinshi, chassis ikomeye no gushyira hamwe imbaraga nyinshi.
Muri moteri ya V-Twin, ubushyuhe ni umwanzi wo kuramba no koroherwa n'umushoferi, bityo moteri ikonjeshwa n'amazi igumana ubushyuhe buhamye kandi bugenzurwa na moteri n'amavuta kugira ngo ikore neza. Kubera ko ibice by'icyuma byaguka kandi bigacika buhoro, ubushobozi bwo kwihanganira ibice bikomeye bushobora kugerwaho binyuze mu kugenzura ubushyuhe bwa moteri, bigatuma habaho imikorere myiza yo gutwara ibintu.
Byongeye kandi, ijwi ryiza rya moteri n'ijwi rishimishije ry'umwotsi bishobora kwiganza kuko urusaku rw'imbere muri moteri rugabanuka bitewe no gukonjesha kw'amazi. Amavuta ya moteri nayo akonjeshwa n'amazi kugira ngo amavuta ya moteri akore neza kandi arambe mu bihe bibi.
Pompe ikonjesha yubatswe mu byuma bipima neza kandi bifunga kugira ngo birambe igihe kirekire, kandi inzira ikonjesha zishyirwa mu buryo bugoye bwo gutwikira igifuniko cya stator kugira ngo bigabanye uburemere n'ubugari bw'ihererekanya ry'amashanyarazi.
Imbere, Revolution Max 1250 ifite imipira ibiri ihindagurikaho dogere 30. Harley-Davidson yakoresheje ubunararibonye bwayo bwinshi mu gusiganwa mu misozi miremire kugira ngo isobanukirwe uburyo Revolution Max 1250 ikoresha imbaraga. Gukurikirana imipira bishobora kunoza uburyo imodoka zitwara mu modoka zimwe na zimwe.
Ku gikoresho cyo gukurura no ku nkoni zihuza hari piston za aluminiyumu zikozwe mu buryo bwa "compression ratio" zifite igipimo cyo gukanda cya 13:1, byongerera moteri imbaraga ku muvuduko wose. Ibyuma bigezweho byo gupima gukanda bituma iki gipimo cyo gukanda gishoboka. Moteri izakenera lisansi ya octane 91 kugira ngo igire imbaraga nyinshi, ariko izakoresha octane nke kandi izirinda guturika bitewe n'ikoranabuhanga rya "knock sensor".
Igice cyo hasi cya piston gifite imigozi bityo nta gikoresho cyo gukanda impeta gikenewe kugira ngo gishyirwemo. Ijipo ya piston ifite agapira gake gatuma intera irushaho gukomera kandi impeta za piston zigabanya intera kugira ngo zirusheho gukora neza. Impande zo hejuru zigizwe n'impeta zikozwe mu buryo bwa anodized kugira ngo zirambe, kandi imiyoboro ikonjesha amavuta yerekeza hasi kuri piston kugira ngo ifashe mu gukuraho ubushyuhe bw'umuriro.
Byongeye kandi, moteri ya V-Twin ikoresha imitwe ya silinda enye (ifata ebyiri n'isohora umwuka ibiri) kugira ngo itange ubuso bunini bushoboka bwa vali. Ibi bituma torque ikomeye kandi inyura neza mu mbaraga zo hejuru kuko umwuka unyura mu cyumba cy'umuriro urushaho kuba mwiza kugira ngo uhuze n'ibisabwa mu kwimura.
Valve y'imyotsi yuzuyemo sodiyumu kugira ngo ubushyuhe burusheho gukwirakwira. Inzira z'amavuta zimanitse mu mutwe zigerwaho binyuze mu ikoranabuhanga rigezweho ryo gusuka, kandi uburemere buragabanuka bitewe n'ubugari buke bw'urukuta rw'umutwe.
Umutwe wa silindiri ukozwe mu cyuma gifite imbaraga nyinshi cya aluminiyumu 354. Kubera ko imitwe ikora nk'aho ifata chassis, yagenewe koroshya iyo ngingo ariko igakomeza hejuru y'icyumba cyo gutwika. Ibi bigerwaho binyuze mu buryo bwo kuvura ubushyuhe.
Umutwe wa silinda ufite kandi camshafts zigenga zo kwinjira no gusohora umwuka kuri buri silinda. Igishushanyo cya DOHC giteza imbere imikorere ya RPM irenga binyuze mu kugabanya ubushyuhe bwa valve train, bigatuma imbaraga zo hejuru ziyongera. Igishushanyo cya DOHC gitanga kandi igihe cy’ingufu zihindagurika zigenga (VVT) kuri cams zinjira n’izisohoka, zikozwe neza ku masilinda y’imbere n’iy’inyuma kugira ngo zigire umugozi munini w’amashanyarazi.
Hitamo porogaramu yihariye ya kamera kugira ngo ubone imikorere wifuza cyane. Ikinyamakuru cy’imashini yo ku ruhande rwa camshaft ni igice cy’ikimenyetso cy’imashini, cyagenewe gukuraho camshaft kugira ngo ikoreshwe cyangwa ivugururwe mu gihe kizaza hatabayeho gukuraho camshaft drive.
Kugira ngo afunge umuyoboro wa valve kuri Revolution Max 1250, Harley yakoresheje uburyo bwo gukora valve ya roller pin hamwe n'ibikoresho byo gukosora imigozi bya hydraulic. Ubu buryo butuma valve na valve actuator (pin) biguma hamwe uko ubushyuhe bwa moteri buhinduka. Ibikoresho byo gukosora imigozi bya hydraulic bituma valve train idakomeza kuyibungabunga, bigatuma ba nyirayo batakaza igihe n'amafaranga. Ubu buryo bukomeza gukanda umuvuduko uhoraho ku gice cy'umuyoboro wa valve, bigatuma camshaft irushaho kuba nziza kugira ngo irusheho gukora neza.
Umuvuduko w'umwuka muri moteri ushyigikiwe n'imigozi ibiri ishyirwa hagati ya silindiri kandi igashyirwa mu mwanya wayo kugira ngo habeho umuyaga mwinshi no kudakoresha umwuka. Gutanga lisansi bishobora gukorwa ku buryo bwihariye kuri buri silindiri, bikongera ubushobozi bwo kuyitwara no kuyikoresha. Aho umwuka uherereye hagati bituma agasanduku k'umwuka ka litiro 11 gahagarara neza hejuru ya moteri. Ubushobozi bw'icyumba cy'umwuka bunoze kugira ngo moteri ikore neza.
Imiterere y'agasanduku k'umwuka ituma habaho umuvuduko uhamye kuri buri gice cy'umwuka, hakoreshejwe uburibwe kugira ngo umwuka mwinshi winjire mu cyumba gitwikwa, byongera imbaraga zisohoka. Agasanduku k'umwuka gakozwe muri nylon yuzuye ikirahure ifite amababa y'imbere yubatswemo kugira ngo gafashe kugabanya ijwi no kugabanya urusaku rw'imodoka. Imyanya y'imodoka ireba imbere irinda urusaku rw'imodoka kure y'umushoferi. Kuvanaho urusaku rw'imodoka bituma ijwi ry'imodoka risohora umwuka rirushaho kuba ryiza.
Umusaruro mwiza wa moteri wemezwa na sisitemu yo kwisiga amavuta yumye ifite ikigega cy'amavuta cyubatswe mu gikoresho cyo gusukamo amavuta. Pompe eshatu zikoresha amavuta zisohora amavuta arenze urugero mu byumba bitatu bya moteri (crankcase, stator chamber na clutch chamber). Abakoresha imodoka babona umusaruro mwiza kuko ibura ry'imbaraga za parasite rigabanuka kuko ibice by'imbere bya moteri bidakenera kuzenguruka mu mavuta arenze urugero.
Ikirahuri cy'imbere kibuza clutch gusharija amavuta ya moteri, ibi bishobora kugabanya ubwinshi bw'amavuta. Mu gushyira amavuta hagati muri crankshaft ku byuma binini n'ibihuza, iyi miterere itanga umuvuduko muke w'amavuta (60-70 psi), bigabanya igihombo cy'imbaraga za parasite ku muvuduko mwinshi wa rpm.
Uburyo bwo kuruhuka bwa Pan America 1250 bugenzurwa n'icyuma gipima imbere kigabanya cyane guhindagura kwa moteri, kikanoza uburyo umushoferi amerewe neza kandi kikongera uburambe bw'ikinyabiziga. Icyuma gipima imbere, kiri mu gikoresho gipima imbere, kigenzura guhindagura kw'ingenzi guterwa na crankpin, piston n'inkoni ihuza, ndetse na "guhinduranya" cyangwa "guhuza ibumoso n'iburyo" guterwa na silinda idahagaze neza. Icyuma gipima imbere kiri hagati y'imirongo y'imbere y'imodoka gitunganya neza imbere kugira ngo kigabanye guhindagura.
Amaherezo, Revolution Max ni imodoka ikoresha imbaraga imwe, bivuze ko moteri na gearbox ifite umuvuduko utandatu biherereye mu mubiri umwe. Iyi clutch ifite disiki umunani zo gukururana zigenewe gutanga imbaraga zihoraho ku muvuduko ntarengwa mu gihe cyose clutch ikora. Imashini zigabanya imbaraga mu modoka ya nyuma zigabanya imbaraga za crankshaft torque mbere yuko zigera kuri gearbox, bityo bigatuma torque ikomeza gukwirakwira.
Muri rusange, Revolution Max 1250 V-Twin ni urugero rwiza rw'impamvu moto za Harley-Davidson zikiboneka cyane.
