Isistimu yokuqondisa esebenzayo ye-asi yangemuva, ehlanganiswe nesistimu yokuqondisa imoto, ihlomisa izimoto eziningi: kusukela kuPorsche 911 GT3/RS kuya kuFerrari 812 Superfast noma iRenault Mégane RS yakamuva.
Lezi zinhlelo azintsha. Kusukela ezinhlelweni eziqondisayo zokuqala kuya ezinhlelweni zakamuva ezisebenzayo, indlela yentuthuko kanye nokuqukatha izindleko zalobu buchwepheshe ibe yinde, kodwa i-ZF isungule okuzoba uhlelo lokuqala olusebenzayo lokuqondisa ukuhlomisa ngokuphelele izimoto zokukhiqiza.
Ngaphandle kokucatshangelwa kwebhrendi, omunye wabakhiqizi bezingxenye zezimoto abaklonyeliswe kakhulu emhlabeni (isihloko sesi-8 silandelana ngo-2015), i-ZF, yashintsha amasistimu okuqondisa asebenzayo e-asi engemuva ngokuvela kwemvelo kwezinhlelo zangaphambilini, ezishibhile futhi ezingenzima kangako.
Ngabe uhlelo lokuqondisa lwe-ZF luqukethe ini?
Ama-Acronyms nama-nomenclatures eceleni, sizobona izinhlobo eziningi zemikhiqizo zisebenzisa isisekelo sohlelo lokuqondisa lwe-ZF, ngaphakathi olubizwa nge-AKC (Active Kinematics Control). Ukusuka kumkhiqizo kuye kumkhiqizo, kushintsha igama kodwa kuzoba yisistimu efanayo.
Igama elinikeziwe iZF lize lisinikeze umkhondo omuhle ngohlobo lwalolu hlelo. Kusukela ekulawuleni amandla e-kinematic, singaphetha ngokushesha ukuthi isistimu isebenza ngamandla okunyakaza, kodwa asifuni ukugxila ezindabeni ze-Applied Physics noma Okuyisisekelo Kwe-Classical Mechanics. Sicela unga...
Lesi simiso silawulwa imojula yokulawula (ECS) ephethe ukuphatha ngenkuthalo, ngamapharamitha atholwe izinzwa zejubane, i-wheel angle kanye nokunyakaza kwesondo lokuqondisa — yonke imisebenzi ekushintshanisweni kwe-engeli yokungena uzwane emasondweni angemuva.
Lokhu kuhluka okufanayo kwi-engeli yokuhlangana kwamasondo angemuva kungakhuphukela ku-3º umehluko phakathi kokuhluka okuhle nokubi. Okusho ukuthi, nge-engeli eyi-negative, amasondo abonwa phezulu anokuqondanisa kwe-convex okwenza u-V, lapho i-vertex yale V efanayo imele i-engeli ku-0 °, eveza ukuvuleka kwamasondo ngaphandle. Okuphambene kwenzeka nge-engeli ephozithivu, lapho ukuqondana kozwane-ngaphakathi kwamasondo kwakha u-Λ, okuveza i-engeli yesondo ngaphakathi.
Ingabe uhlelo lwe-ZF AKC lukwazi kanjani ukushintsha i-engeli yozwane kumasondo e-axle yangemuva?
Njengezinhlelo zakudala, zonke zisebenzisa ama-hydraulic noma ama-electro-hydraulic actuators. I-ZF's i-electrohydraulic futhi inezinhlobo ezimbili ezihlukene: noma njenge i-actuator emaphakathi noma ekabili . Endabeni yezimoto ezisebenza kahle, ama-electro-hydraulic actuators abekwe ekumisweni kwesondo ngalinye asetshenziswa.
Eqinisweni, lapho izimoto zifakwe ama-actuator amabili, zithatha indawo yengalo elengayo engenhla, lapho enye ingalo ye-crosslink ihlangana nezingalo ezingenhla. Ukusebenza kwama-actuator kuphendula ngokuqondile okokufaka okuvela kumojula yokulawula ye-ECS, ngesikhathi sangempela, eshintsha i-engeli yokuhlangana kwamasondo e-axle angemuva.
Lusebenza kanjani uhlelo lwe-ZF AKC?
Njengoba sekushiwo, okokufaka esikunikeza isondo lokuqondisa, isondo langaphambili i-angle yokujika nesivinini, ivumela imodyuli yokulawula ye-ECS ukucacisa ukuhluka kwesistimu yokuqondisa esebenzayo. Empeleni, ngesivinini esiphansi noma ekuqondiseni ukupaka, isiteringi esisebenzayo sishintsha i-engeli yamasondo angemuva siye kolunye uhlangothi nangaphambili, sinciphise i-engeli ejikayo futhi sivumela ukupaka okuhambisanayo.
Uma ushayela ngesivinini esiphezulu (kusuka ku-60 km/h) amandla okuqondisa asebenzayo aqinisekisa ukuzinza okwengeziwe emakhoneni. Kulesi sigaba amasondo angemuva ajikela ohlangothini olufanayo nangaphambili.
Uma imoto ishayelwa ngaphandle kokunyakaza kwesondo lokuqondisa, imojuli yokulawula ithatha ngokuzenzakalelayo ukuthi ayisebenzi, ngaleyo ndlela yonga ukusetshenziswa kwamandla. Eqinisweni, uhlelo lokuqondisa olusebenzayo lwe-ZF luwuhlelo lwe-“Steering on Demand”, kodwa futhi luwuhlelo lwe-“Power on Demand”.
I-ZF yathatha iminyaka ukwenza intando yeningi le sistimu yokuqondisa esebenzayo futhi i-Porsche yayingomunye wabakhiqizi bokuqala ukuhlanganisa lesi sizukulwane esisha sokuqondisa okusebenzayo njengochungechunge ngo-2014. Ngo-2015, ngemva konyaka wokuvuthwa kohlelo, i-Ferrari yalandela indlela efanayo. Esikhathini esizayo kungase kube cishe wonke amamodeli ezemidlalo anikezwe ukuhambisana kwesisombululo sezobuchwepheshe i-ZF esithuthukile.
