EBD Brake Force Distribution System - kufotokozera ndi mfundo ya ntchito

Pofuna kuthana ndi kugawanikanso kwamphamvu kwa kulemera kwagalimoto motsatira ma axle, zida zakale zama hydraulic zidagwiritsidwa ntchito kuwongolera mphamvu yama brake pa ma axle amodzi kapena awiri kutengera kuyimitsidwa. Kubwera kwa makina othamanga kwambiri a ABS ndi zida zofananira, izi sizikufunikanso. Chigawo cha anti-lock braking system, chomwe chimayang'anira kukakamiza pamene pakati pa mphamvu yokoka imasuntha mozungulira galimotoyo, imatchedwa EBD - Electronic Brake Distribution, ndiko kuti, kugawa kwamagetsi amagetsi.

Kodi ntchito ya EBD m'galimoto ndi yotani?

Kugawidwa kwa kulemera kwa nsinga pamodzi ndi ma axles a galimoto kumakhudzidwa ndi zinthu ziwiri - static ndi dynamic. Yoyamba imatsimikiziridwa ndi kukweza galimotoyo, sikutheka kuyika malo opangira mafuta, okwera ndi katundu m'njira yakuti malo awo ochuluka agwirizane ndi galimoto yopanda kanthu. Ndipo mu dynamics, vekitala ya mathamangitsidwe olakwika amawonjezedwa ku vekitala ya mphamvu yokoka pa braking, molunjika perpendicular ku mphamvu yokoka. Chotsatiracho chidzasuntha chiwonetserocho kupita kumsewu womwe uli m'njira. Mawilo akutsogolo adzakwezedwanso, ndipo gawo la zolemetsa lidzachotsedwa kumbuyo.

Ngati chodabwitsa ichi chinyalanyazidwa mu dongosolo ananyema, ndiye ngati zipsinjo za ma cylinders ananyema kutsogolo ndi ma axles kumbuyo ndi ofanana, mawilo kumbuyo akhoza kutsekereza kale kwambiri kuposa kutsogolo. Izi zipangitsa kuti pakhale zochitika zingapo zosasangalatsa komanso zowopsa:

• pambuyo pa kusintha kwa kutsetsereka kwa nkhwangwa yakumbuyo, galimotoyo imataya kukhazikika, kukana kwa mawilo kuti asasunthike motsatana ndi nthawi yayitali kudzakhazikitsidwanso, zovuta zazing'ono zomwe zimakhalapo nthawi zonse zidzatsogolera kutsetsereka kwa lateral kwa chitsulocho. ndiko, kudumpha;
• mphamvu yonse ya braking idzachepa chifukwa cha kuchepa kwa coefficient of friction ya mawilo akumbuyo;
• kuchuluka kwa matayala akumbuyo kumawonjezeka;
• dalaivala adzakakamizika kuchepetsa mphamvu pa ma pedals kuti asalowe mumsewu wosalamulirika, potero athetse kupanikizika kwa mabuleki akutsogolo, zomwe zidzachepetsanso mphamvu ya braking;
• Galimoto idzataya kukhazikika kwamayendedwe, zochitika za resonance zitha kuchitika zomwe zimakhala zovuta kwambiri kuziletsa ngakhale kwa dalaivala wodziwa zambiri.

Oyang'anira omwe amagwiritsidwa ntchito kale adalipira pang'ono chifukwa cha izi, koma adachita molakwika komanso mosadalirika. Maonekedwe a dongosolo ABS poyang'ana koyamba amathetsa vutoli, koma kwenikweni zochita zake sikokwanira. Chowonadi ndi chakuti anti-lock braking system nthawi yomweyo imathetsa ntchito zina zambiri, mwachitsanzo, imayang'anira kusafanana kwa msewu pansi pa gudumu lililonse kapena kugawanso kulemera chifukwa cha mphamvu za centrifugal pamakona. Kugwira ntchito movutikira ndikuwonjezera zambiri ndikugawanso kulemera kumatha kupunthwa pazotsutsana zingapo. Choncho, m'pofunika kulekanitsa kulimbana ndi kusintha kulemera nsinga mu dongosolo osiyana zamagetsi ntchito masensa ofanana ndi actuators monga ABS.

Komabe, mapeto a ntchito ya machitidwe onsewa adzakhala yankho la ntchito zomwezo:

• kukonza chiyambi cha kusintha kwa kutsetsereka;
• kuthamanga kusintha payokha kwa mabuleki gudumu;
• kusunga kukhazikika kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake;
• pazipita ogwira deceleration.

Seti ya zida sizisintha.

Kapangidwe ka mfundo ndi zinthu

Kugwiritsa ntchito EBD kumagwiritsidwa ntchito:

• gudumu liwiro masensa;
• Thupi la valavu ya ABS, kuphatikizapo dongosolo la mavavu olowetsa ndi kutsitsa, pampu yokhala ndi chowonjezera cha hydraulic ndi olandirira okhazikika;
• chigawo chowongolera zamagetsi, gawo la pulogalamu yomwe ili ndi algorithm ya EBD.

Pulogalamuyo amasankha otaya ambiri deta amene mwachindunji zimadalira kugawa kulemera, ndi ntchito nawo, potsitsa ABS pafupifupi chipika.

Algorithm ya zochita

Dongosolo limawunikidwa motsatana momwe galimoto ilili molingana ndi data ya ABS:

• kusiyana kwa magwiridwe antchito a pulogalamu ya ABS ya ma axles akumbuyo ndi akutsogolo akuphunziridwa;
• zisankho zomwe zapangidwa zimakhazikitsidwa mwa mawonekedwe a zosintha zoyambira zowongolera ma valve otsitsa a njira za ABS;
• kusintha pakati pa kuchepetsa kupanikizika kapena kugwiritsira ntchito njira zoletsa zoletsa;
• ngati kuli kofunikira, kubwezera kutengerapo kulemera kwa chitsulo cha kutsogolo, dongosololi lingagwiritse ntchito mphamvu ya pampu ya hydraulic kuti iwonjezere mphamvu kutsogolo kwa mabuleki, zomwe ABS yoyera sichita.

Ntchito yofananirayi ya machitidwe awiriwa imalola kuyankha kolondola kwa kutsika kwa nthawi yayitali komanso kusuntha kwapakati pa mphamvu yokoka chifukwa cha kukweza kwagalimoto. Mulimonse momwe zingakhalire, mphamvu yokoka ya mawilo anayi onse idzagwiritsidwa ntchito mokwanira.

The drawback yekha wa dongosolo akhoza kuonedwa ntchito yake ntchito aligorivimu ndi zipangizo monga ABS, ndiko kuti, ena kupanda ungwiro pa mlingo panopa chitukuko. Pali zoperewera zomwe zimagwirizanitsidwa ndi zovuta komanso zosiyanasiyana za misewu, makamaka malo oterera, dothi lotayirira komanso lofewa, zowonongeka za mbiri pamodzi ndi zovuta zamsewu. Koma pakubwera matembenuzidwe atsopano, nkhanizi zikuthetsedwa pang’onopang’ono.
