Kufotokozera ndi momwe ntchito imagwirira ntchito pa EBD

Chidule cha EBD chimayimira "Electronic Brake Distribution", kutanthauza "electronic brake force distribution system". EBD imagwira ntchito limodzi ndi njira zinayi za ABS ndipo ndi pulogalamu yowonjezera. Zimakuthandizani kuti mugawire bwino mphamvu ya braking pa mawilo, malingana ndi katundu wa galimotoyo, ndipo amapereka kulamulira kwakukulu ndi kukhazikika pamene akuwomba.

Mfundo yogwirira ntchito ndi kapangidwe ka EBD

Panthawi yoyendetsa mabuleki mwadzidzidzi, mphamvu yokoka ya galimoto imasunthira kutsogolo, kuchepetsa katundu pa ekisi yakumbuyo. Ngati pakali pano mphamvu braking pa mawilo onse ofanana (zomwe zimachitika mu magalimoto osagwiritsa ananyema kulamulira mphamvu), mawilo kumbuyo akhoza kwathunthu oletsedwa. Izi zimabweretsa kutayika kwa kukhazikika kwa njira motsogozedwa ndi mphamvu zam'mbali, komanso kugwedezeka ndi kutaya mphamvu. Komanso, kusintha mphamvu braking n'kofunika pokweza galimoto ndi okwera kapena katundu.

Pankhani yomwe braking imachitika pakona (pakatikati pa mphamvu yokoka imasinthidwa kupita ku mawilo omwe akuyenda mumtunda wakunja) kapena mawilo osunthika amagunda pamalo osiyanasiyana (mwachitsanzo, pa ayezi), machitidwe a dongosolo limodzi la ABS sangathe. zokwanira.

Vutoli litha kuthetsedwa ndi dongosolo logawa mphamvu ya brake, lomwe limalumikizana ndi gudumu lililonse padera. Muzochita, izi zikuphatikizapo ntchito zotsatirazi:

• Kutsimikiza kwa kuchuluka kwa kutsetsereka pamsewu pagudumu lililonse.
• Kusintha kwa kuthamanga kwa madzimadzi ogwirira ntchito mu mabuleki ndi kugawa kwa mphamvu zowonongeka malinga ndi kumamatira kwa mawilo pamsewu.
• Kusunga kukhazikika kolunjika mukakumana ndi mphamvu zam'mbali.
• Kuchepetsa mwayi wothamanga kwagalimoto panthawi ya braking ndi ngodya.

Zinthu zazikulu zadongosolo

Mwachidziwitso, dongosolo logawira mphamvu ya brake limachokera ku dongosolo la ABS ndipo lili ndi zinthu zitatu:

• Zomverera. Amalemba zambiri pa liwiro laposachedwa la gudumu lililonse. Mu EBD iyi imagwiritsa ntchito masensa a ABS.
• Electronic control unit (gawo lowongolera lomwe limafanana ndi machitidwe onse awiri). Amalandira ndi kukonza zambiri za liwiro, amasanthula ma braking mikhalidwe ndikuyendetsa ma valve oyenerera.
• Hydraulic block ya ABS system. Imasintha kupanikizika mu dongosolo mwa kusinthasintha mphamvu zowonongeka pa mawilo onse malinga ndi zizindikiro zomwe zimaperekedwa ndi unit control unit.

Njira yogawa mphamvu yama brake

M'malo mwake, ntchito yamagetsi a brake force distribution EBD ndi kuzungulira kofanana ndi kachitidwe ka ABS ndipo imakhala ndi magawo awa:

• Kusanthula ndi kufananiza ma braking forces. Imayendetsedwa ndi gawo lowongolera la ABS pamawilo akumbuyo ndi akutsogolo. Ngati mtengo woikidwiratu wapyola, algorithm ya zochita zoyikidwiratu mu kukumbukira gawo lowongolera la EBD imayatsidwa.
• Kutseka ma valves kuti musunge kuthamanga kwa ma gudumu. Dongosolo limazindikira nthawi yomwe gudumu limayamba kutsekereza ndikukonza kupanikizika pamlingo wapano.
• Kutsegula ma valve otulutsa mpweya ndi kuchepetsa kuthamanga. Ngati chiwopsezo cha kutsekeka kwa magudumu chikupitilira, gawo lowongolera limatsegula valavu ndikuchepetsa kuthamanga kwa ma cylinders ogwirira ntchito.
• Kuwonjezeka kwamphamvu. Pamene kuthamanga kwa gudumu sikudutsa pakhomo lotsekera, pulogalamuyi imatsegula ma valve olowetsamo ndipo motero imawonjezera kuthamanga kwa dera lopangidwa ndi dalaivala pamene chopondapo chikanikizidwa.
• Pomwe mawilo akutsogolo ayamba kutseka, njira yogawa ma brake mphamvu imazimitsidwa ndipo ABS imatsegulidwa.

Chifukwa chake, dongosololi limayang'anira mosalekeza ndikugawa mphamvu za braking ku gudumu lililonse m'njira yabwino kwambiri. Komanso, ngati katundu kapena okwera pamipando yakumbuyo amanyamulidwa m'galimoto, kugawidwa kwa mphamvu kudzakhala kochuluka kuposa kusuntha kwamphamvu kwapakati pa mphamvu yokoka kutsogolo kwa galimotoyo.

Ubwino ndi kuipa

Ubwino waukulu ndi wogawira mphamvu yamagetsi yamagetsi imapangitsa kuti athe kuzindikira bwino mphamvu yama braking agalimoto, kutengera zinthu zakunja (kutsitsa, kumakona, ndi zina). Pankhaniyi, dongosolo limagwira ntchito zokha, ndipo ndikokwanira kukanikiza chopondapo kuti muyambitse. Komanso, dongosolo la EBD limakupatsani mwayi woti muphwanye nthawi yayitali popanda kugwedezeka.

Choyipa chachikulu ndichakuti, pankhani yogwiritsa ntchito matayala okhazikika m'nyengo yachisanu, mukamagwira mabuleki pogwiritsa ntchito njira yogawa mphamvu ya EBD, poyerekeza ndi mabuleki wamba, mtunda wa braking ukuwonjezeka. kuipa ndi mmene tingachipeze powerenga odana loko mabuleki kachitidwe.

M'malo mwake, kugawa kwamagetsi pamagetsi a brake Force EBD ndikothandizira kwambiri ku ABS, ndikupangitsa kuti ikhale yapamwamba kwambiri. Imayamba kugwira ntchito isanayambike anti-lock braking system, kukonzekera galimotoyo kuti ikhale yabwino komanso yabwino.
