I-Rigidity, umqondo oyinhloko kusichazamazwi sowesilisa, nasezicini ezihlukahlukene kakhulu. “Insizwa” eshaywa kakhulu kuthiwa “iqinile”; oyindoda kuthiwa unentshebe “eqinile”; lowo wesifazane onomzimba omuhle uthi “uqinile” (…); umuntu obuthakathaka uzibiza ngokuthi “othambile”; ivila lizibiza “thambile”. Hhayi-ke, futhi kungcono ukuma lapha ngaphandle kwalokho sesiyazi ukuthi ingxoxo izophelelaphi...
Kodwa bawutholile umqondo akunjalo? Okuqinile kuhle, okuthambile kubi . Futhi nge-chassis yemoto ifana nse, kodwa ngezizathu ezahlukene.
Njalo uma umakhi eqala imodeli entsha, kufika indaba yokuqina-kwanda lapha, kwanda lapho, kwanda lapho. Kodwa kungani ukuqina kwe-chassis kubaluleke kangaka? Yilo mbuzo esizozama ukuwuphendula namuhla.
Ukuqina kubalulekile ezicini ezimbili: ukunethezeka nokuziphatha . Uma kukhulu ukuqina kwe-chassis, kukhulu ukumelana ne-torsional eyivezayo. Amandla e-Torsional, nawo, awalutho ngaphandle kwengcindezi i-chassis edlula kuyo ngokubhuleka, ukusheshisa futhi ngaphezu kwakho konke(!) amajika nezimbobo imoto ebhekene nazo. Kubalulekile ukuthi imoto imelane “nokuqina” kule ngcindezi ukuze ukumiswa kusebenze ngendlela.
Uma imoto yakhiwe, esinye sezici ezibhekwayo ekuthuthukisweni kwayo yi-suspension geometry. I-geometry yokumiswa izobeka ikhono lemoto, noma cha, ukukhulisa ukusebenza kwesondo nokuqinisekisa inani elithile lokunethezeka nokusebenza kahle.
Okwenzekayo uma i-chassis ingaqinile ngokwanele ukuthi igoba ngaphansi kwengcindezi ebesikhuluma ngayo. Futhi lapho ukugoba, okuzokwenzeka ukuthi i-geometry yokumiswa ishintshiwe, okungukuthi, ukumiswa kuzosebenza ekucabangeni okungazange kuthuthukiswe.
Cabanga ngephepha bese ekugcineni kwephepha ucabange ngesondo. Noma iyiphi ingcindezi ekhishwa eshidini ibangela ukuthi elinye "lamasondo" lilahlekelwe ukuthintana kahle elinakho nendawo. Kalula nje, lokhu kunjalo nange-chassis.
Esinye isici esithonya ukuqina ukunethezeka kokugibela. Uma i-chassis ingaqini kakhulu, inani lokudlidliza elifinyelela ekhabetheni liba likhulu, ngoba yonke imoto izosebenza njengebhokisi le-resonance, ikhulise lokhu kudlidliza kusuka emasondweni kuya kuso sonke isakhiwo. Ngokuphambene, uma i-chassis iqinile, lokhu kudlidliza akufinyeleli kukhabethe ngoba abakwazi “ukuhamba” ngesakhiwo semoto.
Kungenxa yalezi zizathu ukuthi izimoto eziguqulekayo zijike, ngokuvamile ngendlela “eyinhlanganisela” encane kunezimoto “ezijwayelekile” eziphuma kuzo. Ukuntuleka kophahla kuhlaka lwe-chassis kufana nokuthatha ukhakhayi lwephiramidi. Wonke amanye ama-vertices aba buthaka. Kungenxa yalezi zizathu ukuthi abakhiqizi bengeza ukuqinisa ku-chassis ye-convertibles: ukuzama ukubuyisela okunye ukuqina okulahlekile lapho uphahla lususwa.
