Mapulogalamu akale omwe sankawasintha sizinasinthe kwambiri m'zaka zapitazi, kotero, malingaliro a matekinoloji ophwanyika ndi waya amasonyeza kusintha kwa nyanja komwe anthu ogwira ntchito komanso anthu ambiri onse akukayikira. Ngakhale kuti machitidwe opangira ma hydraulic ali ndi vuto lawo, pali chinthu cholimbikitsa kwambiri pokhala ndi mgwirizano weniweni, wathanzi pakati pa phazi lanu ndi mapepala ophwanyika kapena nsapato zomwe zili pamakona anayi a galimoto yanu. Kupuma kwa waya komwe kumagwirizanitsa, ndiye chifukwa chitukukochi chikuwoneka ngati chowopsa kwambiri kuposa njira zamagetsi zamagetsi kapena ngakhale waya .
Mtonthozi Wotonthoza Wopanda Mafuta
Momwe njira zowonongeka kwa miyambo zakhala zikugwira ntchito kwa zaka makumi ambiri ndikuti kukanikiza pa phokoso lopumitsa kumapanga makina osokoneza bongo omwe amagwiritsidwa ntchito poyambitsa nsapato kapena zitsulo zamadzimadzi. Mu machitidwe akale, kupalasa kumagwira ntchito mwachindunji pa kapangidwe kamadzimadzimadzi kamene kamadziwika ngati msilikali wamkulu. Masiku ano, nyongolotsi yotsekemera, yomwe nthawi zambiri imagwiritsidwa ntchito, imakweza mphamvu ya pedal ndipo imakhala yophweka mosavuta.
Pamene mbuye wamagetsi atsegulidwa, amachititsa kuti magetsi azitsuka mumzere wokhotakhota. Kenaka kupanikizika kumeneku kumagwira ntchito pamagulu a akapolo omwe amapezeka pa gudumu lililonse, lomwe limapangitsa rotor pakati pa mapepala a brake kapena kupangira nsapato zothamangira panja kupita ku ng'oma.
Mankhwala osakanizidwa masiku ano ndi ovuta kwambiri kuposa amenewa, koma akugwirabe ntchito chimodzimodzi. Mankhwala osokoneza bongo kapena osungunuka amatha kuchepetsa kuchuluka kwa mphamvu zomwe dalaivala ayenera kuzigwiritsa ntchito, ndipo matekinoloje monga anti-lock lock ndi mayendedwe amtundu amatha kuyambitsa kapena kumasula mabaki.
Magetsi ndi electro-hydraulic brakes akhala akugwiritsidwa ntchito pamakwerero. Popeza magalimoto amatha kale kugwiritsira ntchito magetsi a zowonongeka ndi kutsegula zizindikiro, ndizosavuta kuyika mu electro-hydraulic master cylinder kapena magetsi opangira magetsi. Njira zamakono zowonjezera zimapezeka kuchokera ku ma OEM angapo, koma mtundu wa mabakiteriya otetezera chitetezo chachititsa kuti magalimoto azimayi akutsutsabe kugwiritsa ntchito zipangizo zamakono zowonongeka.
Electro-Hydraulic Brakes Imani Mphindi
Mbewu yamakono yowonongeka ndi waya imagwiritsa ntchito njira yamagetsi yosakaniza. Machitidwewa akadali ndi makina osungira madzi, koma dalaivala samangokhalira kumangika mbuye wake wamakina mwachindunji pamsana pake. M'malo mwake, mchimake wamakina amavomerezedwa ndi magetsi kapena mpweya umene umayang'aniridwa ndi gawo lolamulira.
Pamene pulogalamuyi imagwedezeka mumagetsi a magetsi, magetsi amatha kugwiritsa ntchito mauthenga ochokera ku masensa ambiri kuti azindikire kuchuluka kwa magetsi omwe amayendetsa gudumu lililonse. Ndondomekoyi ingagwiritsire ntchito mphamvu yowonjezera mphamvu yamtundu wa caliper.
Kusiyana kwakukulu kwakukulu pakati pa electro-hydraulic ndi miyambo yowumitsa madzi osakaniza ndi kuchuluka kwa mavuto. Electro-hydraulic brake systems amagwira ntchito pansi pa zovuta kwambiri kuposa miyambo ya makolo. Mafuta a hydraulic amagwira ntchito pafupi ndi 800 PSI pansi pazolowera zoyendetsa galimoto, pamene Sensotronic electro-hydraullic systems akukhala ndi mavuto pakati pa 2,000 ndi 2,300 PSI.
Mitundu ya Electromechanical Systems Yowonongeka ndi Waya
Ngakhale mafakitale apangidwe amagwiritsabe ntchito ma electro-hydraulic systems, teknoloji yowonongeka ndi waya imachotsa ma hydraulic kwathunthu. Makina awa sakhala akuwonetseratu mtundu uliwonse wopanga zochitika chifukwa cha kutetezeka koyambitsa machitidwe, koma wakhala akufufuza kwambiri ndikuyesedwa.
Mosiyana ndi ma electro-hydraulic brakes, zonsezi zimagwiritsidwa ntchito pa magetsi. Anthu ogwiritsira ntchito makinawa amagwiritsa ntchito makompyuta m'malo mwa hydraulic slave cylinders, ndipo chilichonse chimayang'aniridwa mwachindunji ndi malo olamulira m'malo mozungulira kwambiri. Machitidwewa amafunikanso zipangizo zina zambiri, kuphatikizapo kutentha, mphamvu yowumitsa, ndi magetsi oyendetsa magetsi m'mphindi iliyonse.
Mabakiteriya amadzimadzi amakhalanso ndi mauthenga ovuta olankhulana kuchokera ku caliper aliyense ayenera kulandira ma data angapo kuti apange mphamvu yoyenera ya kusweka. Ndipo chifukwa cha kutetezeka kofunikira kwa machitidwewa, kawirikawiri payenera kukhala ndi basi yowonjezera, yachiwiri yopereka deta yaiwisi kwa osunga.
Nkhani yotetezeka yotchedwa Brake-by-Wire Technology
Ngakhale kuti magetsi oyendetsa magetsi ndi electromechanical systems angathe kukhala otetezeka kusiyana ndi kachitidwe kachitidwe kachitidwe kachitidwe ka chikhalidwe, chifukwa chokhoza kuyanjana kwambiri ndi ABS, ESC, ndi ma technologies ena ofanana, nkhawa za chitetezo zawabwezeretsa. Zomwe zimayambitsidwa kale zimatha komanso sizingatheke, koma kutaya kwakukulu kwa mphamvu ya hydraulic kumapangitsa kuti dalaivala athe kuimitsa kapena kuchepetsa, ngakhale kuti zovuta zowonjezereka zamagetsi zimakhala ndi zifukwa zambiri zolephera.
Zosowa zoyendetsera ntchito, ndi zina zotsatila za chitukuko chotetezera chitetezo monga kusweka-ndi-waya, zimayendetsedwa ndi miyezo yodzitetezera monga ISO 26262
Ndani Amapereka Brake-by-Wire Technology?
Kuchulukanso ndi machitidwe omwe angathe kugwira ntchito ndi kuchepa kwa deta kudzatha kupanga zipangizo zamakono zowonongeka zamagetsi zowonjezera zokwanira kuti anthu ambiri azitha kulandira ana, koma pokhapokha pano OEMs angapo akhala akuyesa mawonekedwe a electro-hydraulic systems.
Toyota anayamba kufalitsa dongosolo la kusinja kwa electro-hydraulic system m'chaka cha 2001 kwa Estima Hybrid, ndipo kusiyana kwake kwa makina opangidwa ndi Electronial Controlled Brake (ECB) wakhala akupezeka kuyambira nthawi imeneyo. Katswiriyu anaonekera koyamba ku US chaka cha 2005 ndi Lexus RX 400h.
Chitsanzo chomwe zipangizo zamakono zowonongeka chifukwa cha kulephera kukhazikitsa ndi pamene Mercedes-Benz adachotsa dongosolo lake la Sensotronic Brake Control (SBC) lomwe linayambitsanso chaka cha 2001. Mchitidwewu unasunthidwa mwakhama mu 2006 mutatha kukumbukira mtengo kwambiri mu 2004, ndi Mercedes akudzinenera kuti izo zidzapereka ntchito zomwezo za SBC yawo kudzera mwa njira yachibadwidwe yopanga madzi.
