Uhlelo lokuqondisa olusebenzayo i-AFS

I-AFS (Active Front Steering) iyisistimu ye-Active Front Steering, okuyisistimu yokuqondisa yakudala ethuthukisiwe. Inhloso enkulu ye-AFS ukwabiwa okufanele kwamandla phakathi kwazo zonke izingxenye zohlelo lokuqondisa, futhi inhloso enkulu ukuthuthukisa ukusebenza kahle kokushayela ngejubane elihlukile. Umshayeli, lapho kukhona ukuqhuba okusebenzayo emotweni, uthola induduzo eyengeziwe nokuzethemba ekushayeleni. Cabanga ngomgomo wokusebenza, idivayisi ye-AFS, nokwehluka kwayo ohlelweni lokuqondisa lwakudala.

Ukuthi isebenza kanjani

Ukuqondisa okusebenzayo kuyasebenza lapho injini iqalwa. Izindlela zokusebenza kwe-AFS zincike esivinini samanje semoto, i-angle yokuqondisa nohlobo lwendawo yomgwaqo. Ngakho-ke, uhlelo luyakwazi ukuguqula kahle isilinganiso segiya (umzamo osuka esiteringini) egiyeni lokushayela, kuya ngemodi yokushayela yemoto.

Lapho imoto iqala ukuhamba, kuvulwa imoto kagesi. Iqala ukusebenza ngemuva kwesiginali evela kunzwa ye-steering angle. Imoto kagesi, ngazimbili zombungu, iqala ukuzungezisa igiya elingaphandle legiya leplanethi. Umsebenzi omkhulu wegiya langaphandle ukuguqula isilinganiso segiya. Ngejubane eliphezulu lokujikeleza kwegiya, lifinyelela kunani eliphansi kakhulu (1: 10). Konke lokhu kunomthelela ekwehliseni isibalo samasondo okushayela kanye nokwanda kokunethezeka lapho kuqhutshwa ngejubane eliphansi.

Ukwanda kwejubane lemoto kuhambisana nokwehla kwejubane lokujikeleza kwemoto kagesi. Ngenxa yalokhu, isilinganiso segiya sikhuphuka kancane (ngokulingana nokwanda kwejubane lokushayela). Imoto kagesi iyeka ukuzungeza ngejubane lika-180-200 km / h, kanti amandla esiteringi aqala ukudluliselwa ngqo kumshini wokuqondisa, futhi isilinganiso segiya silingana no-1: 18.

Uma isivinini semoto siqhubeka nokukhuphuka, imoto kagesi izoqala futhi, kepha kulokhu izoqala ukuzungeza iye kolunye uhlangothi. Kulokhu, inani lamagiya lingafika ku-1: 20. Isondo lokushayela liba elicijile kakhulu, ukuthuthuka kwalo kukhuphukela ezindaweni ezibi kakhulu, okuqinisekisa ukuhamba okuphephile ngejubane elikhulu.

I-AFS ibuye isize ukuzinzisa imoto lapho i-asi engemuva ilahlekelwa ukudonsa nalapho ibhuleka ezindaweni ezishelelayo. Ukuzinza kokuqondisa kwezimoto kugcinwa kusetshenziswa uhlelo lweDynamic Stability Control (DSC). Kungemva kwezimpawu ezivela ezinzwa zayo lapho i-AFS ilungisa khona i-angle yokuqondisa yamasondo angaphambili.

Esinye isici se-Active Steering ukuthi asikwazi ukukhutshazwa. Lolu hlelo lusebenza ngokuqhubekayo.

Idivayisi nezinto eziyinhloko

Izingxenye eziyinhloko ze-AFS:

• I-steering rack enezimpahla zeplanethi nemoto kagesi. Igiya leplanethi lishintsha ijubane le-shaft shaft. Lo mshini uqukethe umqhele (i-epicyclic) negiya lelanga, kanye nebhulokhi leziphuphutheki kanye nesithwali. U-gearbox weplanethi utholakala kushaft yokuqondisa. Imoto kagesi ijikelezisa igiya lendandatho ngegiya lesibungu. Lapho leli sondo legiya lizungeza, isilinganiso segiya semishini siyashintsha.
• Izinzwa zokufaka. Kuyadingeka ukukala amapharamitha ahlukahlukene. Ngesikhathi sokusebenza kwe-AFS, kusetshenziswa okulandelayo: inzwa yesondo lokushayela, izinzwa zezinjini ezisebenza ngogesi, izinzwa zohlelo lokuqina ezinamandla Inzwa yokugcina kungenzeka ilahlekile, futhi i-engeli ibalwa ngokuya ngamasignali avela kuzinzwa ezisele.
• Iyunithi yokulawula nge-elekthronikhi (ECU). Ithola amasiginali avela kuzo zonke izinzwa. Ibhulokhi licubungula isignali, bese lithumela imiyalo kumadivayisi aphezulu. I-ECU ibuye isebenzisane ngenkuthalo nalezi zinhlelo ezilandelayo: I-Servotronic electro-hydraulic power steering, uhlelo lokuphathwa kwezinjini, i-DSC, uhlelo lokufinyelela ezimotweni.
• Bopha izinduku namathiphu.
• Isiteringi.

Izinzuzo nokungalungi

Uhlelo lwe-AFS lunezinzuzo ezingenakuphikwa kumshayeli: lwandisa ukuphepha nokunethezeka ngenkathi ushayela. I-AFS uhlelo lwe-elekthronikhi olukhethwa ngaphezu kwama-hydraulic ngenxa yezinzuzo ezilandelayo:

• ukudluliswa okunembile kwezenzo zomshayeli;
• ukuthembeka okwandisiwe ngenxa yezingxenye ezimbalwa;
• ukusebenza okuphezulu;
• isisindo esincane.

Kwakungekho ukushiyeka okuphawulekayo ku-AFS (ngaphandle kwezindleko zayo). Ukuqondisa okusebenzayo akuvamile ukungasebenzi kahle. Uma, noma kunjalo, kungenzeka ukulimaza ukugcwaliswa kwe-elekthronikhi, ngeke ukwazi ukumisa uhlelo ngokwakho - udinga ukuthatha imoto ne-AFS isevisi.

Isicelo

I-Active Front Steering ingukuthuthuka kokuthengisa kwe-BMW automaker yaseJalimane. Okwamanje, i-AFS ifakiwe njengenketho ezimotweni eziningi zalolu hlobo. I-steering esebenzayo yaqala ukufakwa ezimotweni zakwa-BMW ngo-2003.

Ukukhetha imoto enesiteringi esisebenzayo, umthandi wemoto uthola induduzo nokuphepha ngenkathi ushayela, kanye nokulawula okulula. Ukuthembeka okwandisiwe kohlelo lwe-Active Front Steering kuqinisekisa ukusebenza okude futhi okungenazinkinga. I-AFS inketho okungafanele inganakwa lapho uthenga imoto entsha.
