Mota Geometry - Wheels

Wheel geometry ndeimwe yeakakosha ma paramita anobata kutyaira, kupfeka matayi, kunyaradza kwekutyaira uye kushandiswa kwemafuta. Kurongeka kwayo kwakaringana kuchakanganisa zvakanyanya kutyaira kwemotokari, pamwe nekubata kwayo. Chinodiwa chikuru ndechekuti mavhiri anokunguruka, asi usatsvedza kana uchikona kana mumutsara wakatwasuka. Iyo geometry inofanirwa kugadzikwa nemazvo pamavhiri ese emota, kwete chete dhiraivha.

Kudzora kwemota kugona kufamba zvakachengeteka uye nekukurumidza sezvinobvira kutenderera uchitenderera uchitevedza nzira yakapihwa. Kushandura nzira yemotokari inogona kudzorwa nekushandura mavhiri. Mavhiri emota dzemumugwagwa haafanire kutsvedza kana achikona, asi anofanirwa kukunguruka kuti afambise simba rakawanda rekutenderera uye rekutenderera sezvinobvira. Kuzadzisa mamiriro aya, kutsauka kwevhiri kubva munzira kunofanirwa kuenzana ne zero. Iyi ndiyo Ackerman inotungamira geometry. Izvi zvinoreva kuti maekisi akatambanudzwa ekutenderera kwemavhiri ose anopindirana pane imwe nzvimbo akarara paaxis yekumashure yakagadziriswa ekisi. Izvi zvinopawo radii yekutenderera kwemavhiri ega. Mukuita, izvi zvinoreva kuti neakisi inodhiraivha, kana mavhiri achitenderedzwa munzira inodiwa, kune imwe nzira yekufambisa yemavhiri nekuda kwenzira dzisina kuenzana dzemavhiri. Panguva yekushanda, mavhiri anokunguruka panzira dzakatenderera. Kona inotenderedza vhiri remukati inotungamira inofanira kunge yakakura kudarika kona yevhiri rekunze. Iyo geometry yemharadzano yakajairika yakakosha mukugadzirisa kunoshanda kwekusiyanisa, mutsauko mumakona ekuchinja mumunwe wemavhiri. Iyi kona yemusiyano inofanirwa kunge yakafanana mune ese madhiri chinzvimbo kana mavhiri achitenderera achienda, i.e. kana atendeuka kurudyi nekuruboshwe.

Kutungamira ekisero geometry equation: cotg β₁  - chidimbu β₂ = B / L, apo B iri chinhambwe chiri pakati pemasanhu akareba emahinji, L ndiyo wheelbase.

Geometric element inokanganisa kubata kwakachengeteka kwemotokari, iko kutyaira mashandiro, kupfeka matai, kunwiwa kwemafuta, kumiswa uye kusungirirwa kwevhiri, giya rekufambisa uye kusakara kwemishini. Nesarudzo yakakodzera yezvikamu, nyika inowanikwa mukati mairi mudhiraivho unogadzikana, masimba ekumhanyisa ari mudhiraivho ari madiki, kupfeka kwezvinhu zvese kushoma, iyo axle mutoro haina unidirectional, uye mutambo wekutungamira wakatemwa. Iyo axle inotakura dhizaini inosanganisira akatiwandei ezvinhu anovandudza chassis dynamics uye inowedzera kutyaira kunyaradzwa uye yakachengeteka kutyaira ruzivo. Chaizvoizvo, uku ndiko kushanduka kweiyo axle yebridge, kusangana kweiyo axle yekumashure, yavo inobhururuka kamwene, nezvimwe.

Iyo yekumhanyisa geometry inokanganiswa zvakanyanya nehunhu hwechassis yemota, iyo yekumisa hunhu uye zvimiro zvematairi, ayo anogadzira simba rekubatana pakati pemotokari nemugwagwa. Mota zhinji nhasi dzakagadzirisa kumashure axle geometry marongero, asi kunyangwe nemota dzisinga gadziriswe, kugadzirisa iyo geometry yemavhiri ese mana kunobvumidza iyo nyanzvi kuona chero kumashure kumashure ekiseti track track uye nekugadzirisa iwo nekugadzirisa iyo yekumberi ekisero. Kurongeka kwemaviri-mavhiri, ayo anongogadzirisa geometry yemavhiri epamberi maererano ne ekisero yemotokari, haachashandi uye haisisiri kushandiswa.

Zviratidzo zvekutungamira zvisina kufanira geometry

Kugadziriswa kusiri iko kwevhiri geometry kunotungamira mukudzikira muhunyanzvi mamiriro emota uye kunoratidzwa nezviratidzo zvinotevera:

• kuneta
• kudzora kwakashata zvivakwa
• kusagadzikana kwenzira inodzorwa yekufamba kwemotokari
• kudengenyeka kwezvikamu zvekushandisa
• kuwedzerwa kupfeka kweanotungamira mativi uye kutsauka kwekutyaira
• kutadza kudzosera mavhiri munzira yekumberi

Iyo yakanakisa vhiri kurongeka kwemota ndeyekugadzirisa ese mana mavhiri. Nerudzi urwu rwegadziriro yejometri, nyanzvi inoisa mudziyo unoratidza pamavhiri mana uye inoyera geometry pamavhiri mana.

Maitiro ekuyera wega paramita yemotokari geometry

• kutarisa uye kugadzirisa iyo yakatarwa mota kukwirira
• kuyerwa kweiyo kusiyanisa kona pane yakapihwa yekudzora kona yekutenderera kweimwe remavhiri anotyairwa
• vhiri kutsauka kona kuyerwa
• kuyerwa kwekubatana
• kuyera kona yekutenderera kwesimbi stub
• kuyera kona yekutenderera kwehumambo
• kuyerwa kwekuyera vhiri
• kuyerwa kwekufananidza kwemasanhu
• kuyerwa kwemuchina mutambo mukutungamira
