Ngezantsi sichaza imilinganiselo ebalulekileyo emisela ukuma, ukulungeleka kunye nokuphathwa kwebhayisikili yeentaba kwaye uchaze indlela echaphazela ngayo ukukhwela.
Siza kuqala ngezinto ezisisiseko, kubandakanywa imiba yazo engacacanga, phambi kokuba sixoxe ngezihloko zejiyometri ezingakhankanywanga kangako kodwa zibaluleke ngokulinganayo.Ekugqibeleni, siza kuhlolisisa indlela ingcamango ehlala ingaqondwa ngayo ye-trajectory ichaphazela ukuphatha.
Ubude betyhubhu yokuhlala bumisela ubungakanani bebhayisikili ngaphezu koyilo "oluncinci, oluphakathi okanye olukhulu".Oku kungenxa yokuba ichaza ubuncinci kunye nobude bokuphakama kwesali kunokumiselwa, kwaye ngoko ke uluhlu lweendawo eziphakamileyo umkhweli unokukhwela ibhayisekile ngokukhululekileyo, okanye uphantsi kangakanani ukulahla isali ukuze ehle.
Umzekelo, iifreyimu ezimbini zobungakanani obuphakathi zihlala zinobude obuhlukeneyo betyhubhu yokuhlala kubakhweli abohlukeneyo.Ngelixa ubude betyhubhu yokuhlala abuchaphazeli ngokuthe ngqo ukuphatha ibhayisekile, ukuphatha okubalulekileyo kunye nemilinganiselo efanelekileyo efana nokufikelela kufuneka ithelekiswe nobude betyhubhu yokuhlala ukugqiba ubude bebhayisekile ngokumalunga nobude bomkhweli.
Umlinganiselo wokufikelela kubude betyhubhu yesitulo uluncedo kakhulu - ezinye iibhayisekile zale mihla zinokufikelela ixesha elide kunemilinganiselo yetyhubhu yokuhlala.
Ingcaciso: Ubude ukusuka kumphezulu wetyhubhu yokuqondisa ukuya kumgca othe tye onqumla kumbindi wepalisti.
Umbhobho oPhezulu oSebenzayo (ETT) unika umbono ongcono wendlela ibhayisekile eziva ngayo xa ukwisali kunokusebenzisa umlinganiselo wetyhubhu esisiseko (ukusuka phezulu kumbhobho wentloko ukuya phezulu kwityhubhu yokuhlala).
Idityaniswe nobude besiqu kunye ne-saddle offset, oku kunika isibonakaliso esihle sendlela ibhayisekile eya kuziva ngayo xa ukhwele kwisali.
Inkcazo: Umgama othe nkqo ukusuka kwiziko le-bracket elisezantsi ukuya phezulu kwiziko letyhubhu yentloko.
Oku kugqiba ukuba i-bar ingaba ephantsi kangakanani ngokumalunga nekhareji.Ngamanye amagama, ichaza ubude obuncinci bebha ngaphandle kwe-spacers phantsi kwebar.Isitaki sikwanobudlelwane obubalulekileyo kodwa obungathandekiyo kumaxabiso…
Inkcazo: Umgama othe tye ukusuka kwisibiyeli esisezantsi ukuya kumbindi ongaphezulu wetyhubhu yentloko.
Kuwo onke amanani aqhelekileyo kwiitshathi zejiyometri yebhayisekile, i-offset inika umbono ongcono wokuba ibhayisekile ingena njani.Ukongeza kubude besiqu, ikwamisela ukuba ingakanani na indawo ibhayisekile ephuma kwisali, kunye ne-angle yesitulo esebenzayo, ekwamisela ukuba ingakanani na indawo ibhayisekile kwisali.Nangona kunjalo, kukho i-caveat encinci, inento yokwenza nokuphakama kwesitaki.
Thatha iibhayisekile ezimbini ezifanayo kwaye uphakamise ityhubhu yentloko yebhayisekile enye ukuze inobude besitaki.Ngoku ukuba ulinganisa uluhlu lwezi bhayisekile zimbini, enye enetyhubhu yentloko ende iya kuba mfutshane.Oku kungenxa yokuba i-angle ye-tube yentloko ayikho ngokuthe nkqo - ngoko ixesha elide ityhubhu yentloko, i-back back top yayo, kwaye ngoko ke imfutshane yokulinganisa ukufikelela.Nangona kunjalo, ukuba usebenzisa i-headphone pads kwibhayisekile yasekuqaleni ukwenzela ukuba ukuphakama kwe-handlebar kufane, amava okukhwela kuzo zombini iibhayisikili aya kufana.
Oku kubonisa indlela ubude bemfumba obuchaphazela ngayo imilinganiselo yoluhlu.Xa uthelekisa umgama owolula phakathi kweebhayisekile, gcina ukhumbula ukuba iibhayisekile ezinobude obuphezulu be-rack ziya kuziva zinde kunoko kucetyiswa ukufunda kwazo.
Eyona ndlela ilula yokulinganisa uluhlu kukubeka ivili lakho langaphambili eludongeni, emva koko ulinganise umgama ukusuka eludongeni ukuya phezulu kwisibiyeli esisezantsi kunye netyhubhu yentloko kwaye uthabathe.
Inkcazo: Umgama ukusuka kumbindi wesibiyeli esisezantsi ukuya kumbindi wezantsi kumbhobho wentloko.
Njengokufikelela, ubude be-downtube bunokubonisa indlela evulekile ngayo ibhayisekile, kodwa oku kuphinde kube nzima ngezinye izinto.
Kanye njengokuba ukufikelela kuxhomekeke kubude bestaki (umahluko kubude phakathi komzantsi wesibiyeli esisezantsi kunye nesibiyeli esisezantsi), kunjalo nobude be-downtube.ityhubhu yentloko.
Oku kuthetha ukuba ubude betyhubhu ephantsi buluncedo kuphela xa uthelekisa iibhayisekile ezinobukhulu obufanayo bevili kunye nobude befolokhwe, ngoko ke umzantsi wombhobho wentloko umalunga nobude obufanayo.Kule meko, ubude bombhobho osezantsi bunokuba luncedo ngakumbi (kunye nenani elinokulinganiswa) kunobude.
Ixesha elide iziko langaphambili, incinci amathuba okuba ibhayisekile incike phambili phezu kwamaqhuma amakhulu okanye i-braking hard.Oku kungenxa yokuba ubunzima bomkhweli buya kuthi ngokwendalo bube semva komphezulu woqhagamshelwano wangaphambili.Yiyo loo nto i-enduro enqumla ilizwe kunye neebhayisekile ezihlayo zinamaziko amade angaphambili.
Kubude obunikiweyo beziko elingasemva, iziko langaphambili elide linciphisa ubungakanani bobunzima bomkhweli obuxhaswa livili langaphambili.Oku kunciphisa ukutsalwa kwevili langaphambili ngaphandle kokuba umkhweli utshintsha isihlalo sakhe phambili okanye umbindi wevili elingasemva nawo uba nde.
Ingcaciso: Umgama othe tye ukusuka kumbindi wesibiyeli esisezantsi ukuya kwi-asi yangasemva (ubude bokuhlala).
Ekubeni iziko levili langaphambili lihlala lide kakhulu kunombindi wevili elingasemva, iibhayisikili zeentaba zikholisa ukuba nokusabalalisa ubunzima bendalo obungasemva.Oku kunokuchatshazelwa ukuba umkhweli ngononophelo ubeka uxinizelelo kwibhari, kodwa kunokudinwa kwaye aziqhelise.
Ngabo bonke ubunzima bomkhweli kwiipedali, umlinganiselo wombindi ongasemva ukuya kwi-wheelbase iyonke imisela ubunzima bokusasazwa ngaphambili nangasemva.
Umbindi ongasemva webhayisekile yentaba imalunga ne-35% ye-wheelbase yayo, ngoko ke ngaphambi kokuba umkhweli abeke ubunzima kwii-handlebars, ukuhanjiswa kobunzima "bendalo" bungama-35% ngaphambili kunye nama-65% ngasemva.
Ivili langaphambili elinobunzima obungama-50% nangaphezulu lidla ngokulungele ukugoba iikona, ngoko ke iibhayisekile ezinomqolo omfutshane wombindi ongasemva kufuneka zifake uxinzelelo oluthe kratya lokutsala ukuphumeza oku.
Kwiindawo eziphakamileyo, ukuhanjiswa kobunzima kuya phambili ngakumbi, ngakumbi phantsi kwe-braking, ngoko ke oku kubaluleke kakhulu kwiikona ezisicaba.
Iziko elingasemva elinesiphumo elide lenza kube lula (ngokudinwa okuncinci) ukufezekisa ulwabiwo lobunzima olulungeleleneyo, olulungele ukutsalwa kwevili langaphambili kwiikona ezithe ngqo.
Nangona kunjalo, okukhona iziko elingasemva lide, kokukhona ubunzima bomkhweli kufuneka buthwale (esebenzisa isibiyeli esisezantsi) ukuphakamisa ivili langaphambili.Ngoko ke iziko elingemva elifutshane linciphisa inani lomsebenzi wezandla, kodwa linyusa inani lomsebenzi ofunekayo ukulayisha ngokufanelekileyo ivili langaphambili ngeehandlebari.
Inkcazo: umgama othe tye phakathi kwe-asi yangaphambili nasemva okanye imigangatho yoqhagamshelwano;Isixa seziko elingasemva kunye nombindi ongaphambili.
Kunzima ukumisela ukuba i-wheelbase ichaphazela njani ukuphatha.Ekubeni i-wheelbase inecandelo elingasemva eliphakathi kunye necandelo eliphambili eliphakathi (emva koko kugqitywe ngokufikelela, i-angle yentloko kunye nefolokhwe ye-offset), imidibaniso eyahlukeneyo yezi zintlukwano inokuvelisa i-wheelbase efanayo kodwa iimpawu zokuphatha ezahlukeneyo..
Ngokubanzi, nangona kunjalo, okukhona i-wheelbase inde, kokukhona ubunzima bomkhweli bunokuchatshazelwa kukuqhobosha, ukutshintsha kwendlela, okanye indawo erhabaxa.Ngaloo ndlela, i-wheelbase ende iphucula uzinzo;kukho ifestile enkulu phakathi xa ubunzima bomkhweli bukude kakhulu (ngaphezu kwee-handlebar) okanye umva kakhulu (iluphu).Oku kunokuba kubi, njengoko i-manual okanye i-bow twist ifuna umzamo ongakumbi.
Kukwakho necala elisezantsi kwiikona ezixineneyo.Okukhona i-wheelbase inde, kokukhona kufuneka ujike ii-handlebars (oku kubizwa ngokuba yi-engile ye-handlebar) ukufumana ibhayisekile kwiradiyasi enikiweyo yokujika.
Ukongeza, umahluko phakathi kwee-arcs ezihamba phambili kunye namavili angasemva uya kuba mkhulu.Yiyo le nto iiveni ezinde zamavili zikholisa ukucinezela amavili angasemva ngaphakathi kwiikona.Ewe, iibhayisekile zasezintabeni azijiki ngendlela enye neeveni okanye izithuthuthu – ivili elingasemva liyakwazi ukutsiba okanye lityibilike ngokujikelana liqinile ukuba kuyimfuneko.
Okukhona uphezulu umphakamo wesibiyeli ongezantsi, kokukhona uphezulu iziko lomkhweli lomxhuzulane, ngoko ibhayisekile ingqiyama ngokulula xa ibetha amaqhuma, ukuqhobosha kanzima, okanye ukukhwela umnqantsa.Ngaloo ndlela, isibiyeli esisezantsi esisezantsi siphucula uzinzo ngendlela efanayo neyenza iwheelbase ende.
Okumangalisayo kukuba, isibiyeli esisezantsi senza ukuba ibhayisekile ibe lula kwiikona.Xa ibhayisekile iphumle ekoneni, ijikeleza i-axis roll (umgca ecaleni komhlaba odibanisa iindawo ezimbini zoqhagamshelwano).Ngokunciphisa iziko lomkhweli we-mass kufuphi ne-axis ye-roll, ubunzima bomkhweli buyancipha xa ibhayisekile ixhomekeke kwi-turn, kwaye isantya somkhweli xa utshintsha ii-angles ezinqamlekileyo (xa ujika ukusuka ekhohlo ukuya kwesobunxele), umzekelo, uyancipha..
Ukuphakama kombindi womxhuzulane womkhweli kunye nebhayisekile engaphezulu kwe-axis ye-roll ibizwa ngokuba ngumzuzu wokuqengqeleka: okukhona kulo mgama, ukucotha kwebhayisekile kuya kutshintsha indlela ebhityileyo.
Ngenxa yoko, iibhayisekile ezinobude obusezantsi bezibiyeli zikholisa ukungena nokuphuma ekujikeni ngokulula.
Umphakamo wesibiyeli osezantsi uchatshazelwa yi-sag yokunqunyanyiswa kunye nokuphakama kohambo oluguqukayo, ngoko ke iihambo ezinde zifuna umphakamo ophakamileyo ongashukumiyo wesibiyeli ukuhlawula uhambo olwandisiweyo lokunqunyanyiswa.Jonga amacandelo angezantsi kwi-sag kunye nejometri eguqukayo.
Ukungalungi kwesibiyeli esisezantsi esisezantsi kuyacaca: kwandisa ithuba lokubamba kwii-pedals okanye i-sprockets emhlabeni.
Kukwafanelekile ukukhumbula ukuba umbindi womxhuzulane webhayisekile kunye nomkhweli udla ngokuba ngaphezu kwemitha ngaphezulu komhlaba, ngoko ke ukuthoba isibiyeli esisezantsi ngesentimitha (ubuninzi obunyusa kakhulu ukunyovwa) kwenza umahluko omncinci wepesenti.
Ingcaciso: Umgama othe nkqo ukusuka kwisiphambuka se-asi ukuya kumbindi wekhareji.
Ukuhla kwesibiyeli esisezantsi ngokwaso akubalulekanga njengoko abanye banokucinga.Abanye abantu babona ukuba umgama we-bracket ephantsi uxhomekeka ngaphantsi kwe-axle ngokuthe ngqo unquma ukuzinza kwebhayisikili ngokujika, njengokungathi i-axis roll axis (umgca ojikayo xa uxhomekeke kwi-axle) ekuphakameni kwe-axle.
Le ngxabano isetyenziswa ekuthengiseni amavili angama-29 ″, ibango lokuba ibhayisekile izinzile ngenxa yesibiyeli esisezantsi sisezantsi kancinci (kunokuba phezulu) kune-axle.
Eyona nto, i-axis ejikelezayo - ngokumalunga ukuthetha - umgca odibanisa iindawo zoqhagamshelwano zamatayara.Umlinganiselo obalulekileyo wokujika kubude bombindi wobunzima ngaphezu kwalo mgca, hayi umphakamo wesibiyeli esisezantsi ngokunxulumene ne-axis.
Ukufaka amavili amancinci kuya kuthoba ukuphakama kwenqwelo, kodwa akuyi kuchaphazela ukuhla kwenqwelo.Oku kuvumela ibhayisekile ukuba itshintshe indlela ebhityileyo ngokukhawuleza kuba ibhayisekile kunye nomkhweli baneziko elisezantsi lobunzima.
Okubangela umdla kukuba, ezinye iibhayisekile (ezifana ne-Pivot's Switchblade) zinee-“chips” ezinokulungiswa ukuphakama ukuze zibuyekeze ubungakanani bamavili obahlukeneyo.Ukuphakama kwesibiyeli esisezantsi kuhlala kufana nevili elincinci, kodwa ukuphakama kwesibiyeli esisezantsi kuyatshintsha.
Oku kubangele utshintsho oluncinci kwindlela yokuphatha ibhayisekile, iphakamisa ukuba ukuphakama kwesibiyeli esisezantsi kwakubalulekile kunokuba kuthotywe isibiyeli esisezantsi.
Nangona kunjalo, ukulahla isibiyeli esisezantsi kusengumlinganiselo oluncedo.Ubude be-BB abuxhomekekanga kubungakanani bevili kuphela, kodwa nakukhetho lwamavili - ukuthelekisa ukwehla kwesibiyeli esisezantsi phakathi kweebhayisekile kubungakanani bevili obunikiweyo kuphelisa oku kuguquguquka.
Okokuqala, i-angle ye-tube yentloko ichaphazela ukuba kude kangakanani i-axle yangaphambili phambi komkhweli.Zonke ezinye izinto zilingana, i-angle yetyhubhu yentloko ekhululekileyo yonyusa iziko eliphambili, isenza ibhayisekile ingabi lula ukungqiyama phambili kwiminqantsa enyukayo, kodwa inciphisa ubunzima bomkhweli ukuya kumlinganiso ongaphambili wonxibelelwano.Ngenxa yoko, abakhweli kusenokufuneka batyhale ngamandla kwiihandlebari ukuze baphephe i-understeer kwiikona ezicandiweyo ezineengile yentloko esezantsi.
