Ijiyomethri Yemoto - Amasondo

I-Wheel geometry ingenye yemingcele ebaluleke kakhulu ethinta ukushayela, ukuguga kwamasondo, ukunethezeka kokushayela kanye nokusetshenziswa kukaphethiloli. Isilungiselelo sayo esilungile sizothinta kakhulu ukusebenza kokushayela kwemoto, kanye nokuphathwa kwayo. Imfuneko eyinhloko ukuthi amasondo ayagingqika, kodwa angasheleli lapho ejika emakhoneni noma emugqeni oqondile. Ijiyomethri kufanele isethwe kahle kuwo wonke amasondo emoto, hhayi nje i-asi esiteringini.

Ukulawuleka kwemoto yikhono lokuhamba ngokuphepha nangokushesha ngangokunokwenzeka ejikeni eligudla umzila othile. Ukushintsha isiqondiso semoto kungalawulwa ngokuphendula amasondo. Amasondo ezimoto zomgwaqo akufanele ashelele lapho zijika emakhoneni, kodwa kufanele zigingqike ukuze zidlulise amandla amaningi aqondisayo kanye nawokuzungeza ngangokunokwenzeka. Ukuze kufezeke lesi simo, ukuchezuka kwesondo ukusuka ohlangothini kufanele kulingane no-zero. Lena i-geometry yokuqondisa ye-Ackerman. Lokhu kusho ukuthi izimbazo ezinwetshiwe zokuzungezisa kwawo wonke amasondo ziyaphambana endaweni eyodwa elele ku-eksisi ye-asi egxilile yangemuva. Lokhu futhi kunikeza i-radii yokujikeleza kwamasondo ngamanye. Ngokusebenza, lokhu kusho ukuthi nge-axle esiteringi, lapho amasondo ephendulwa ngendlela oyifunayo, kuba khona i-angle yokuqondisa ehlukile yamasondo ngenxa yezindlela zamasondo ezingalingani. Ngesikhathi sokusebenza, amasondo agingqika kumathrekhi ayindilinga. I-engeli ephendukayo yesondo lomhlahlandlela wangaphakathi kufanele ibe nkulu kune-engeli ephendukayo yesondo langaphandle. I-geometry ye-intersection evamile ibalulekile ekunqumeni okusebenzayo kokuhlukana, umehluko kuma-engeli woshintsho ezinzwaneni zamasondo. Le engeli yomehluko kufanele ifane kuzo zombili izindawo zokuqondisa lapho amasondo ejikela lapho eya ngakhona, okungukuthi lapho ejika kwesokudla nakwesokunxele.

Ukulinganisa i-axle geometry equation: cotg β₁  - iqoqo β₂ = B / L, lapho u-B eyibanga phakathi kwama-axes amahinji, u-L uyi-wheelbase.

Izakhi zeJiyomethri zithinta ukuphathwa okuphephile kwemoto, izici zayo zokushayela, ukugqoka isondo, ukusetshenziswa kukaphethiloli, ukumiswa nokunamathiselwa kwesondo, amagiya okuqondisa nokugqokwa kwemishini. Ngokukhethwa kwamapharamitha afanelekile, umbuso utholwa lapho isitering sizinzile, amasondo ayo asebenza esiteringini mancane, ukugqokwa kwazo zonke izinto kuncane, umthwalo we-ekseli awuqondisi, futhi umdlalo wokuqondisa uyanqunywa. Idizayini yokuthwala i-axle ifaka izinto eziningi ezithuthukisa amandla we-chassis futhi zithuthukise induduzo yokushayela nokuhlangenwe nakho okuphephile kokushayela. Ngokuyinhloko, lokhu kungukufuduka kwe-asi ye-bhuloho, ukuhlangana kwe-ekseli langemuva, umlomo wombhobho ondizayo, njll.

Ijiyometri yokuqondisa ithonywe kakhulu yizici zeshassis yemoto, izici zokumiswa kanye nezakhiwo zamathayi, ezenza ukuxhumana okunamandla phakathi kwemoto nomgwaqo. Izimoto eziningi namuhla zinamasethingi e-axle engemuva enziwe ngendlela oyifisayo, kepha ngisho nasezimotweni ezingaguquguquki, ukulungisa i-geometry yawo womane amasondo kuzovumela uchwepheshe ukuthi abone noma yiziphi izinkinga zethrekhi ye-axle yangemuva futhi azilungise ngokulungisa i-asi engaphambili. Ukuqondaniswa kwamasondo amabili, okulungisa kuphela i-geometry yamasondo angaphambili maqondana ne-ekseli lemoto, akusasebenzi futhi akusasetshenziswa.

Izimpawu zejometri yokuqondisa engafanele

Ukulungiswa okungalungile kwe-geometry yamasondo kuholela ekuwohlokeni kwesimo sobuchwepheshe bemoto futhi kubonakala ngezimpawu ezilandelayo:

• ukugqoka isondo
• izindawo zokulawula ezingezinhle
• ukungazinzi kwesiqondisi esilawulwayo sokuhamba kwemoto
• ukudlidliza kwezingxenye zedivayisi yokulawula
• ukwanda kokugqoka kwezingxenye zokuqondisa ngakunye nokuphambuka kwesiteringi
• ukungakwazi ukubuyisa amasondo ngokuya phambili

Ukuqondanisa kahle kwamasondo emoto wukuhlela wonke amasondo amane. Ngalolu hlobo lwesilungiselelo sejiyomethri, uchwepheshe ufaka idivayisi ekhombisayo kuwo wonke amasondo amane futhi akale i-geometry kuwo wonke amasondo amane.

Inqubo yokulinganisa amapharamitha ngamanye wejometri yemoto

• ukubheka nokulungisa ubude bemoto obubekiwe
• ukulinganisa kwe-engeli yokwehluka ku-engeli yokulawula enikeziwe yokujikeleza yelinye lamasondo aqondiswayo
• ukukalwa kwesondo kwe-angle deflection
• isilinganiso sokuhlangana
• ukulinganisa i-engeli yokujikeleza kwe-asi ye-stub
• ukulinganisa kwe-angle yokuthambekela kwe-kingpin
• isilinganiso sokufakwa kwesondo
• ukulinganisa ukufana kwamazembe
• ukulinganisa kokudlala ngomshini ekushayeleni
