Mfundo ndi kugwiritsa ntchito galimoto abs sensor
Mfundo yogwirira ntchito ya abs yamagalimoto ndi:
Mu braking mwadzidzidzi, kudalira kwambiri tcheru gudumu liwiro sensa anaika pa gudumu lililonse, loko gudumu amapezeka, ndipo kompyuta nthawi yomweyo amawongola kukakamiza wowongolera kuti athetse kupanikizika kwa pampu ananyema gudumu kuteteza gudumu loko. Dongosolo la abs lili ndi abs pump, wheel speed sensor ndi brake switch.
Udindo wa abs system ndi:
1, pewani kuwonongeka kwagalimoto, kuonjezera mtunda wa braking, kukonza chitetezo chagalimoto;
2, kuwongolera magwiridwe antchito agalimoto;
3, kuteteza gudumu mu braking ndondomeko;
4. Onetsetsani kuti dalaivala amatha kuwongolera komwe akulowera pamene akuwotcha ndikuletsa chitsulo chakumbuyo kuti zisatsetserekere.
Udindo wa ABS, monga momwe dzinalo likusonyezera, ntchito yayikulu ya anti-lock braking system ndikuletsa gudumu kuti lisatseke chifukwa champhamvu kwambiri pakuwonongeka kwagalimoto, zomwe zimapangitsa kuti galimoto isamayende bwino. chipangizo. Mwachitsanzo, tikapeza chopinga patsogolo pathu, galimoto yokhala ndi makina a ABS imatha kuwongolera mosavuta kupewera mabuleki mwadzidzidzi nthawi imodzi.
Galimoto ikakhala kuti ilibe zida za ABS mu braking yadzidzidzi, chifukwa mphamvu ya braking ya mawilo anayi ndi ofanana, kugunda kwa tayala pansi kumakhala kofanana, panthawiyi galimotoyo idzakhala yovuta kwambiri kutembenuka. , ndipo n'zosavuta kuchititsa ngozi ya galimoto kutaya ulamuliro. Ndikokwanira kuwona momwe dongosolo la ABS lilili lofunikira pachitetezo chathu choyendetsa. Sitiyenera kuda nkhawa ndi izi, tsopano muyezo wadziko lonse wakakamiza makampani agalimoto munjira yopanga magalimoto ayenera kukhala odana ndi loko a ABS.
Ndiye kodi ABS anti-lock braking system imagwira ntchito bwanji? Musanamvetsetse mfundo yake yogwira ntchito, choyamba tiyenera kumvetsetsa zigawo za ABS anti-lock system, ABS makamaka imapangidwa ndi gudumu lothamanga sensa, unit control electronic, brake hydraulic regulator, brake master silinda ndi mbali zina. Galimoto ikafunika kusweka, sensor yothamanga pa gudumu imazindikira kuthamanga kwa mawilo anayi panthawiyi, kenako ndikuitumiza ku VCU (wowongolera magalimoto), gawo lowongolera la VCU lidzasanthula zizindikiro izi. mkhalidwe wa galimoto panthawiyi, ndiyeno VCU imatumiza lamulo loletsa kuthamanga kwa brake ku ABS pressure regulator (ABS pump).
Pamene ABS pressure regulator imalandira malangizo a brake pressure control, imayang'anira mwachindunji kapena mosalunjika kupsinjika kwa ma brake a njira iliyonse poyang'anira valavu yamkati ya solenoid ya ABS pressure regulator, kuti isinthe ma braking torque ya mawilo anayi, kuti sinthani kuti ikhale yomatira pansi, ndikuletsa gudumu kuti lisatsekedwe chifukwa champhamvu yama braking.
Madalaivala ambiri akale omwe amawona apa angaganize kuti nthawi zambiri timayendetsa "spot brake" imatha kusewera anti-lock effect. Tiyenera kutsindika apa kuti lingaliro ili ndi lachikale, ndipo tinganene kuti njira ya "spot brake" intermittent braking yakhudza chitetezo cha galimoto.
N’chifukwa chiyani mukunena choncho? Izi ndikuyamba kuyambira pa chiyambi cha "spot brake", chomwe chimatchedwa "spot brake", sichikhala ndi anti-lock system ya ABS pagalimoto poponda mopanda ntchito yowonongeka ya pedal, kotero kuti gudumu braking mphamvu nthawi zina ayi, pofuna kupewa zotsatira za loko gudumu. Tikumbukenso kuti tsopano galimoto ndi muyezo ABS odana loko dongosolo, mitundu yosiyanasiyana ya odana loko dongosolo adzakhala ndi zosiyana, koma makamaka akhoza kudziwika chizindikiro 10 ~ 30 nthawi/sekondi, chiwerengero cha braking 70. ~ Nthawi 150 / sekondi pafupipafupi kuphedwa, malingaliro awa ndi kupha pafupipafupi sikutheka kufikira.
ABS anti-lock braking system ikuyenera kukhala mu braking mosalekeza kuti igwire bwino ntchito yake. Tikamayendetsa "mabuleki" mokhazikika, makina a anti-lock braking a ABS amalandira chizindikiro nthawi ndi nthawi, ndipo ABS sichitha kugwira ntchito bwino, zomwe zingayambitse kuchepa kwa mabuleki komanso mtunda wautali kwambiri. .
