Ngezansi sichaza izilinganiso ezibalulekile ezinquma ukuma, ukufaneleka kanye nokuphathwa kwebhayisikili lezintaba futhi sichaze ukuthi zikuthinta kanjani ukugibela.
Sizoqala ngezisekelo, okuhlanganisa izici zazo ezingacacile, ngaphambi kokuxoxa ngezinye zezihloko zejiyomethri ezishiwo kancane kodwa ezibalulekile ngokulinganayo.Okokugcina, sizohlola ukuthi umqondo ovame ukungaqondakali we-trajectory uthinta kanjani ukuphatha.
Ubude bethubhu yesihlalo bunquma ubukhulu bebhayisikili ngaphezu komklamo "oncane, ophakathi noma omkhulu".Lokhu kungenxa yokuthi ichaza ubude obuncane kanye nobukhulu obukhulu ihhashi elingasethwa kubo, ngakho-ke ububanzi bobude umgibeli angakwazi ukugibela ibhayisikili ngokunethezeka, noma ukuthi baphansi kangakanani ihhashi ukuze behle.
Isibonelo, amafreyimu amabili amaphakathi avame ukuba nobude beshubhu lezihlalo ezihlukene kubagibeli abahlukene.Nakuba ubude beshubhu lesihlalo akuthinti ngokuqondile ukuphatha ibhayisikili, ukuphatha okubalulekile nezilinganiso ezifanele ezifana nokufinyelela kufanele kuqhathaniswe nobude beshubhu lesihlalo ukuze kunqunywe ubude bebhayisikili ngokuqhathaniswa nobude bomgibeli.
Isilinganiso sokufinyelela kubude beshubhu lesihlalo siwusizo ikakhulukazi - amanye amabhayisikili esimanje anokufinyelela okude kunobukhulu beshubhu lesihlalo.
Incazelo: Ubude obusuka phezulu kweshubhu lokuqondisa ukuya kulayini ovundlile onqamula phakathi nendawo yesihlalo.
I-Efficient Top Tube (ETT) inikeza umbono ongcono wokuthi ibhayisikili lizwakala livuleke kangakanani uma usesihlalo sehhashi kunokusebenzisa isilinganiso seshubhu lesisekelo (kusuka phezulu kweshubhu lekhanda ukuya phezulu kweshubhu yokuhlala).
Kuhlanganiswe nobude besiqu kanye nesihlalo sehhashi, lokhu kunikeza inkomba enhle yokuthi ibhayisikili lizozizwa kanjani lapho ligibele isihlalo sehhashi.
Incazelo: Ibanga eliqondile ukusuka enkabeni yabakaki engezansi ukuya phezulu kwesikhungo seshubhu lekhanda.
Lokhu kunquma ukuthi ibha ingaba phansi kangakanani maqondana nekalishi.Ngamanye amazwi, ichaza ubude obuncane bebha ngaphandle kwama-spacers ngaphansi kwebha.Isitaki siphinde sibe nobudlelwano obubalulekile kodwa obungathandeki kuzilinganiso...
Incazelo: Ibanga elivundlile ukusuka kubakaki abaphansi kuya phezulu maphakathi neshubhu lekhanda.
Kuzo zonke izinombolo ezijwayelekile kumashadi ejiyomethri yebhayisikili, i-offset inikeza umbono ongcono kakhulu wokuthi ibhayisikili lingena kanjani.Ngaphezu kobude besiqu, iphinde inqume ukuthi ibhayisikili livuleke kangakanani kusihlalo, kanye ne-engeli yesihlalo esebenzayo, ephinde inqume ukuthi ibhayisikili livuleke kangakanani kusihlalo.Nokho, kukhona i-caveat encane, ihlobene nokuphakama kwesitaki.
Thatha amabhayisikili amabili afanayo bese uphakamisa ishubhu lekhanda lebhayisikili elilodwa ukuze libe nobude besitaki obuningi.Manje uma ukala ububanzi bala mabhayisikili amabili, leli elineshubhu lekhanda elide lizoba lifushane.Lokhu kungenxa yokuthi i-engeli yeshubhu yekhanda ayiqondile - ngakho-ke uma ishubhu lekhanda lide, ingaphezulu lihlehla kakhulu, ngakho-ke isilinganiso sokufinyelela siba sifushane.Kodwa-ke, uma usebenzisa ama-headphone pads ebhayisikilini langempela ukuze ukuphakama kwesibambo kufane, isipiliyoni sokugibela kuwo womabili amabhayisikili sizofana.
Lokhu kubonisa ukuthi ukuphakama kwenqwaba kuthinta kanjani izilinganiso zobubanzi.Uma uqhathanisa ibanga eliphakathi kwamabhayisikili, khumbula ukuthi amabhayisikili anama-rack aphakeme azozizwa emude kunalokho okungasikiselwa ukufunda kwawo ngokunwebeka.
Indlela elula yokulinganisa ububanzi ukubeka isondo lakho langaphambili odongeni, bese ukala ibanga ukusuka odongeni ukuya phezulu kubakaki abaphansi kanye neshubhu lekhanda bese ukhipha.
Incazelo: Ibanga ukusuka enkabeni yabakaki abaphansi ukuya phakathi nendawo engaphansi kweshubhu lekhanda.
Njengokufinyelela, ubude be-downtube bungabonisa ukuthi ibhayisikili livule kangakanani, kodwa lokhu kuphinde kube nzima ngezinye izici.
Njengoba nje ukufinyelela kuncike ekuphakameni kwesitaki (umehluko wobude phakathi kwezansi kubakaki abaphansi nabakaki abaphansi), kanjalo nobude beshubhu ephansi.ithubhu lekhanda.
Lokhu kusho ukuthi ubude beshubhu eliphansi buwusizo kuphela uma uqhathanisa amabhayisikili anosayizi wesondo ofanayo nobude bemfoloko, ngakho-ke ishubhu lekhanda eliphansi lilingana nobude obufanayo.Kulokhu, ubude bompompi obuphansi bungaba inombolo ewusizo (futhi elinganisekayo) kunobude.
Uma isikhungo sangaphambili siba side, mancane amathuba okuthi ibhayisikili lincike phambili phezu kwamaqhubu amakhulu noma ukubhuleka kanzima.Lokhu kungenxa yokuthi isisindo somgibeli ngokwemvelo sizoba ngemuva kwendawo yokuxhumana yangaphambili.Yingakho i-enduro enqamula izwe kanye namabhayisikili e-downhill anezikhungo ezide ezingaphambili.
Ngobude obunikeziwe besikhungo sangemuva, isikhungo esingaphambili eside sinciphisa ingxenye yesisindo somgibeli esisekelwe yisondo langaphambili.Lokhu kunciphisa ukudonsa kwamasondo angaphambili ngaphandle uma umgibeli egudluza isihlalo sakhe phambili noma imaphakathi nesondo langemuva nalo liba lide.
Incazelo: Ibanga elivundlile ukusuka phakathi nendawo kubakaki abaphansi ukuya ku-ekseli yangemuva (ubude bokuhlala).
Njengoba isikhungo sesondo langaphambili ngokuvamile side kakhulu kunesikhungo sesondo elingemuva, amabhayisikili asezintabeni avame ukuba nokusabalalisa kwesisindo sangemuva esingokwemvelo.Lokhu kungase kunqandwe uma umgibeli ebeka ukucindezela ibha, kodwa kungase kukhathale futhi kuzijwayeze.
Ngaso sonke isisindo somgibeli kumaphedali, isilinganiso sendawo engemuva ne-wheelbase esiphelele sinquma ukusabalaliswa kwesisindo ngaphambili nangemuva.
Isikhungo esingemuva sebhayisikili elivamile lasezintabeni singama-35% e-wheelbase yalo, ngakho-ke ngaphambi kokuba umgibeli abeke isisindo phezu kwezibambo, ukusatshalaliswa kwesisindo "semvelo" kungu-35% ngaphambili nangemuva kuka-65%.
Isondo langaphambili elinesisindo esingu-50% noma ngaphezulu livamise ukuthi lilungele ukugoba amakhona, ngakho-ke amabhayisikili ane-wheelbase ephakathi nendawo emfushane ngemuva kufanele afake ingcindezi yokudonsa ukuze afeze lokhu.
Ekwehleni okukhuphukayo, ukusatshalaliswa kwesisindo kuba phambili kakhulu noma kunjalo, ikakhulukazi ngaphansi kwe-braking, ngakho-ke lokhu kusebenza kakhulu kumakhona ayisicaba.
Isikhungo esingemuva eside esiholelayo senza kube lula (ngokukhathala okuncane) ukuzuza ukusabalalisa kwesisindo okunokulinganisela, okulungele ukudonsa kwamasondo angaphambili emakhoneni aqondile.
Nokho, uma isikhungo esingemuva siba side, umgibeli kufanele asithwale (esebenzisa ubakaki ongezansi) ukuze aphakamise isondo langaphambili.Ngakho isikhungo sangemuva esifushane sinciphisa inani lomsebenzi wezandla, kodwa sandisa inani lomsebenzi odingekayo ukuze ulayishe kahle isondo langaphambili ngokusebenzisa izibambo.
Incazelo: ibanga elivundlile phakathi kwama-ekseli angaphambili nangemuva noma izindawo zokuthintana;isamba sesikhungo esingemuva kanye nesikhungo esingaphambili.
Kunzima ukucacisa ukuthi i-wheelbase ikuthinta kanjani ukuphatha.Njengoba i-wheelbase inengxenye emaphakathi engemuva kanye nengxenye emaphakathi engaphambili (eyokugcina yona inqunywa ngokufinyelela, i-head angle nefork offset), izinhlanganisela ezihlukene zalezi ziguquguqukayo zingakhiqiza i-wheelbase efanayo kodwa izici zokubamba ezihlukene..
Nokho, ngokujwayelekile, uma i-wheelbase iba yinde, kuzothikamezeka kancane ukusatshalaliswa kwesisindo somgibeli ukubhuleka, ukushintsha kokuhlehla, noma indawo embi.Ngalowo mqondo, i-wheelbase ende ithuthukisa ukuzinza;kunefasitela elikhudlwana phakathi lapho isisindo somgibeli sikude kakhulu (ngenhla kwezibambo) noma emuva kakhulu (iluphu).Lokhu kungaba kubi, njengoba i-manual noma i-bow twist idinga umzamo owengeziwe.
Kukhona futhi okuphambene namakhona aqinile.Uma i-wheelbase iba yinde, kulapho udinga ngokwengeziwe ukujika izibambo (lokhu kubizwa ngokuthi i-engeli yesibambo) ukuze uthole ibhayisikili endaweni engaba yithuba lokujika.
Ngaphezu kwalokho, umehluko phakathi kwama-arcs adlula kuwo amasondo angaphambili nangemuva uzoba mkhulu.Yingakho amaveni ama-long wheelbase ejwayele ukumpintsha amasondo angemuva ngaphakathi emakhoneni.Yebo, amabhayisikili asezintabeni awajiki ngendlela efanayo namaveni noma izithuthuthu - isondo elingemuva liyakwazi ukugxuma noma ukushibilika ngokushintshana okuqinile uma kudingeka.
Ukuphakama kwebakaki abaphansi, kulapho isikhungo somgibeli sikhuphuka khona, ngakho ibhayisikili liyancika kalula lapho lishaya amabhampa, ibhuleki eliqinile, noma imiqansa.Ngalowo mqondo, abakaki abaphansi abaphansi bathuthukisa ukuzinza ngendlela efanayo naleyo eyenziwa ngayo i-wheelbase ende.
Okuxakayo ukuthi ubakaki ongezansi nabo benza ibhayisikili lishesha kakhulu emakhoneni.Uma ibhayisikili lihlezi ekhoneni, lizungeza i-axis ejikelezayo (umugqa ogudle umhlaba oxhumanisa izindawo ezimbili zokuthintana).Ngokwehlisa isikhungo sesisindo somgibeli eduze ne-axis roll, ukwehla kwesisindo somgibeli kuncipha lapho ibhayisikili lincika ejikeni, futhi umfutho womgibeli lapho eshintsha ama-engeli anciphile (lapho ejika esuka kwesokunxele ukuya kwesokunxele), isibonelo, uyancishiswa..
Ukuphakama kwesikhungo se-gravity yomgibeli kanye nebhayisikili ngaphezu kwe-axis roll kubizwa ngokuthi i-roll moment: uma likhulu leli banga, ukuhamba kancane kwebhayisikili kuzoshintsha isiqondiso esithambile.
Ngenxa yalokho, amabhayisikili anabakaki abaphakeme abaphansi avame ukungena futhi aphume emajikeni kalula.
Ubude bobakaki abangezansi buthintwa ukuhlehla kokumiswa kanye nokuphakama kokugibela okuguquguqukayo, ngakho uhambo olude ludinga ukuphakama kukabakaki ophansi okumile okuphezulu ukunxephezela uhambo olwenyukile lokumiswa.Bona izigaba ezingezansi ku-sag nejometri eguqukayo.
Ububi bobakaki obuphansi obuphansi busobala: kwandisa amathuba okubamba amaphedali noma ama-sprockets aphansi.
Kuyafaneleka futhi ukukhumbula ukuthi indawo ephakathi kwamandla adonsela phansi ebhayisikili kanye nomgibeli kuvame ukuba ngaphezu kwemitha ngaphezu komhlabathi, ngakho ukwehlisa ubakaki ongezansi ngesentimitha (inani elikhulisa kakhulu ukuhamba ngezinyawo) kwenza umehluko omncane wephesenti.
Incazelo: Ibanga eliqondile ukusuka ku-axle junction ukuya maphakathi nekalishi.
Ukwehla kobakaki ongezansi akubalulekile njengoba abanye bengacabanga.Abanye abantu babona ukuthi ibanga eliphansi lebakaki elilenga ngaphansi kwe-axle linquma kanjani ukuzinza kwebhayisikili ngokushintshana, njengokungathi i-axis roll yebhayisikili (umugqa ophendukayo lapho uncike ekuphendukeni) usekuphakameni kwe-axle.
Le mpikiswano isetshenziswa ekukhangiseni kwamasondo angu-29″, kuthiwa ibhayisikili lizinze kakhulu ngenxa yokuba ubakaki ongezansi uphansi kancane (kunokuba ube phezulu) kune-asili.
Empeleni, i-axis egoqayo - ukusho cishe - umugqa oxhuma izindawo zokuthintana zamasondo.Isilinganiso esibalulekile sokuphenduka ukuphakama kwenkaba yesisindo ngaphezu kwalo mugqa, hhayi ubude bobakaki abaphansi uma kuqhathaniswa ne-eksisi.
Ukufaka amasondo amancane kuzokwehlisa ukuphakama kwekalishi, kodwa ngeke kuthinte ukwehla kwekalishi.Lokhu kuvumela ibhayisikili ukuthi lishintshe indlela enciphile ngokushesha kakhulu ngoba ibhayisikili nomgibeli banesikhungo esiphansi sobuningi.
Kuyathakazelisa ukuthi amanye amabhayisikili (njenge-Pivot's Switchblade) “anama-chips” alungiseka ukuphakama ukuze anxephezele osayizi abahlukahlukene bamasondo.Ubude bobakaki obungezansi buhlala bufana nesondo elincane, kodwa ubude bobakaki obungezansi buyashintsha.
Lokhu kubangele ushintsho oluncane kakhulu ekuphathweni kwebhayisikili, okuphakamisa ukuthi ukuphakama kukakaki okuphansi kwakubalulekile kunokwehla kwabakaki abaphansi.
Nokho, ukulahla ubakaki ongezansi kuseyisinyathelo esiwusizo.Ukuphakama kwe-BB akuncikile kuphela kusayizi wesondo, kodwa futhi nasekukhetheni isondo - ukuqhathanisa ukwehla kwabakaki abaphansi phakathi kwamabhayisikili ngosayizi wesondo onikeziwe kuqeda lokhu kuhlukahluka.
Okokuqala, i-engeli yeshubhu yekhanda ithinta ukuthi ikude kangakanani i-ekseli yangaphambili phambi komgibeli.Zonke ezinye izinto zilingana, i-engeli yeshubhu yekhanda exegayo inyusa isikhungo esingaphambili, okwenza ibhayisikili lingabi lula ukuncika ekwehleni okukhuphukayo, kodwa linciphise isisindo somgibeli ukuya esilinganisweni sangaphambili sokuxhumana.Ngenxa yalokho, abagibeli kungase kudingeke baphushe kakhulu izibambo ukuze bagweme ukuqondisa ngaphansi emakhoneni ayisicaba ane-engeli yekhanda eliphansi.
