Steering Knuckle, yomwe imadziwikanso kuti "ram Angle", ndi imodzi mwamagawo ofunikira a mlatho wowongolera magalimoto, omwe amatha kupangitsa kuti galimotoyo iziyenda mokhazikika ndikusuntha komwe mukuyendetsa bwino.
Ntchito ya chiwongolero chowongolera ndikusamutsa ndi kunyamula katundu wa kutsogolo kwa galimoto, kuthandizira ndikuyendetsa gudumu lakutsogolo kuti lizizungulira mozungulira kingpin ndikupanga galimotoyo kutembenuka.Poyendetsa galimoto, imakhala ndi katundu wosiyanasiyana, choncho imayenera kukhala ndi mphamvu zambiri
Ma gudumu poyikira magawo
Pofuna kusunga bata la galimoto ikuyenda molunjika, chiwongolero chowongolera ndi kuchepetsa kuvala pakati pa tayala ndi zigawo zake, chiwongolero, chowongoleredwa ndi chingwe chakutsogolo pakati pa atatu ndi chimango chiyenera kukhala ndi malo ena achibale. , ichi chimakhala ndi malo ena achibale oyika omwe amatchedwa chiwongolero chowongolera, chomwe chimatchedwanso kutsogolo kwa gudumu.Kuyika koyenera kwa gudumu lakutsogolo kuyenera kuchitidwa: kungapangitse galimoto kuyenda mosasunthika molunjika popanda kugwedezeka;Pali mphamvu zochepa pa chiwongolero pamene chiwongolero;Chiwongolero pambuyo pa chiwongolero chimakhala ndi ntchito yobwereranso bwino.Palibe skid pakati pa tayala ndi pansi kuti muchepetse kugwiritsa ntchito mafuta ndikutalikitsa moyo wantchito wa tayala.Kuyika kwa mawilo akutsogolo kumaphatikizapo kupendekeka kwa kingpin kumbuyo, kupendekeka kwa kingpin mkati, kupendekeka kwa gudumu lakutsogolo ndi mtolo wakutsogolo.[2]
Kingpin Rear Angle
The kingpin ali mu ndege longitudinal ya galimotoyo, ndipo kumtunda kwake kuli kumbuyo Angle Y, ndiko kuti, Angle pakati pa kingpin ndi mzere ofukula wa nthaka mu ndege longitudinal galimoto, monga momwe chithunzi.
Pamene kingpin ali ndi kumbuyo kumbuyo v, mphambano ya kingpin axis ndi msewu udzakhala kutsogolo kwa malo olumikizana pakati pa gudumu ndi msewu.Galimoto ikamayenda mowongoka, ngati chiwongolerocho chapatutsidwa mwangozi ndi mphamvu zakunja (kutembenukira kumanja kukuwonetsedwa ndi muvi pachithunzi), mayendedwe agalimotowo amapatukira kumanja.Panthawiyi, chifukwa cha mphamvu ya centrifugal ya galimoto yokha, pa malo okhudzana ndi b pakati pa gudumu ndi msewu, msewu umakhala ndi gudumu.Mphamvu yochitira pa gudumu imapanga torque L yomwe imagwira ntchito pamzere wa pini yayikulu, komwe kumayenderana ndendende ndi komwe kumapatuka kwa gudumu.Pansi pa mphamvu ya torque iyi, gudumu lidzabwerera ku malo oyambirira apakati, kuti atsimikizire kuyendetsa molunjika kwa galimoto, kotero mphindi ino imatchedwa mphindi yabwino,
Koma makokedwe sayenera kukhala aakulu kwambiri, apo ayi kuti athetse kukhazikika kwa makokedwe pamene chiwongolero, dalaivala ayenera kusonyeza mphamvu yaikulu pa mbale chiwongolero (chotchedwa chiwongolero cholemera).Chifukwa kukula kwa mphindi yokhazikika kumadalira kukula kwa mphindi mkono L, ndipo kukula kwa mphindi mkono L zimadalira kukula kwa kumbuyo kupendekera Angle v.
Tsopano v Angle yomwe imagwiritsidwa ntchito kwambiri siposa 2-3 °.Chifukwa cha kuchepa kwa kuthamanga kwa matayala ndi kuwonjezeka kwa elasticity, torque yokhazikika ya magalimoto amakono othamanga kwambiri imawonjezeka.Chifukwa chake, V Angle imatha kuchepetsedwa mpaka kuyandikira zero kapena ngakhale zoyipa.
