I-Steering Knuckle, ekwabizwa ngokuba yi "ram Angle", yenye yezona ndawo zibalulekileyo kwibhulorho yokuqhuba imoto, enokwenza ukuba imoto ibaleke ngokuzinzileyo kwaye idlulisele icala ekuqhutywa ngalo ngovakalelo.
Umsebenzi we-knuckle yokulawula ukuhambisa kunye nokuthwala umthwalo ongaphambili wemoto, ukuxhasa kunye nokuqhuba ivili langaphambili ukujikeleza kwi-kingpin kwaye wenze imoto ijike. Kwimeko yokuqhuba isithuthi, sithwala umthwalo wempembelelo eguquguqukayo, ngoko ke kufuneka ukuba ube namandla aphezulu
Iiparamitha zokubeka ivili lokuqhuba
Ukuze ugcine uzinzo lwemoto ebaleka kumgca othe tye, isibane sokuqhuba kunye nokunciphisa ukunxiba phakathi kwetayara kunye namalungu, ivili lokuqhuba, iqhosha lokuqhuba kunye ne-asi yangaphambili phakathi kwezi zintathu kunye nesakhelo kufuneka sigcine indawo ethile. , oku kunofakelo lwendawo ethile yesalamane ebizwa ngokuba yi-steering wheel positioning, ekwaziwa ngokuba yi-front wheel positioning. Ukumiswa okuchanekileyo kwevili langaphambili kufuneka kwenziwe: kunokwenza imoto iqhube ngokuthe tye kumgca othe tye ngaphandle kokugungqa; Kukho amandla amancinci kwipleyiti yokulawula xa uqhuba; Ivili lokuqhuba emva kokuqhuba linomsebenzi we-automatic positive return. Akukho skid phakathi kwetayara kunye nomhlaba ukunciphisa ukusetyenziswa kwamafutha kunye nokwandisa ubomi benkonzo yetayara. Ukuma kwevili langaphambili kubandakanya ukuthambeka kwe-kingpin ngasemva, ukuthambeka kwe-kingpin ngaphakathi, ivili langaphambili lithambekele ngaphandle kunye nevili langaphambili lithambeka. [2]
Kingpin ngasemva engile
I-kingpin ikwinqwelo-moya ye-longitudinal yesithuthi, kwaye inxalenye yayo ephezulu ine-Angle Y engasemva, oko kukuthi, i-Angle phakathi kwe-kingpin kunye nomgca othe nkqo womhlaba kwinqwelo-moya ye-longitudinal yesithuthi, njengoko kuboniswe kumfanekiso.
Xa i-kingpin inotyekelo olungasemva v, indawo yokuhlangana ye-axis ye-kingpin kunye nendlela iya kuba phambi kwendawo yoqhagamshelwano phakathi kwevili kunye nendlela. Xa imoto iqhuba ngendlela ethe tye, ukuba ivili lokuqhuba liphambukiswa ngengozi ngamandla angaphandle (ukuphambuka ngasekunene kuboniswa lutolo olusemfanekisweni), isalathiso semoto siya kuphambukela ngasekunene. Ngeli xesha, ngenxa yesenzo samandla e-centrifugal yemoto ngokwayo, kwindawo yoqhagamshelwano b phakathi kwevili kunye nendlela, indlela yenza i-reaction lateral kwivili. I-reaction force kwivili yenza i-torque L esebenza kwi-axis ye-pin engundoqo, isalathiso esichasene ngqo necala lokuphambuka kwevili. Ngaphantsi kwesenzo salo torque, ivili liya kubuyela kwindawo yokuqala ephakathi, ukuze kuqinisekiswe ukuhamba okuthe tye kwemoto, ngoko lo mzuzu ubizwa ngokuba ngumzuzu olungileyo,
Kodwa i-torque akufanele ibe nkulu kakhulu, ngaphandle koko ukuze unqobe ukuzinza kwe-torque xa uqhuba, umqhubi kufuneka asebenzise amandla amakhulu kwi-steering plate (ebizwa ngokuba yi-steering heavy). Ngenxa yokuba ubukhulu bexesha lokuzinzisa buxhomekeke kubukhulu bengalo yomzuzu L, kunye nobukhulu bengalo yomzuzwana L ixhomekeke kubukhulu be-Angle yokuthambekela yangasemva.
Ngoku i-v Angle esetyenziswa ngokuqhelekileyo ayikho ngaphezu kwe-2-3 °. Ngenxa yokuncipha koxinzelelo lwetayara kunye nokwanda kwe-elasticity, i-torque yokuzinza yezithuthi zanamhlanje ezinesantya esiphezulu ziyanda. Ngoko ke, i-Engile ye-V inokuncitshiswa ukuba isondele ku-zero okanye ide ibe negative.
