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 yaikulu ya anti-lock braking system ndi kuteteza gudumu kuti lisatseke chifukwa cha mphamvu yothamanga kwambiri pakagwa mwadzidzidzi galimotoyo, zomwe zimapangitsa kuti galimotoyo iwonongeke. Mwachitsanzo, tikapeza chopinga patsogolo pathu, galimoto yokhala ndi makina a ABS imatha kuwongolera mosavuta kupewera mabuleki mwadzidzidzi nthawi imodzi.
Pamene galimoto ilibe ndi dongosolo la ABS mu braking mwadzidzidzi, chifukwa mphamvu ya braking ya mawilo anayi ndi yofanana, kugwedezeka kwa tayala pansi kumakhala kofanana, panthawiyi galimotoyo imakhala yovuta kwambiri kutembenuka, ndipo n'zosavuta kuchititsa ngozi ya galimoto kulephera. 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. Pamene galimoto ikufunika kusweka, gudumu liwiro kachipangizo pa gudumu adzazindikira gudumu liwiro chizindikiro cha mawilo anayi panthawiyi, ndiyeno kutumiza kwa VCU (wolamulira galimoto), ndi VCU ulamuliro wagawo kusanthula zizindikiro izi kudziwa mmene galimoto panthawiyi, ndiyeno VCU akutumiza ananyema kuthamanga ulamuliro lamulo kwa ABS mpope wolamulira (ABS).
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 igwirizane ndi zomatira pansi, ndikuletsa gudumu kuti lisatsekedwe chifukwa champhamvu kwambiri yamabuleki.
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 ndi kuyambira chiyambi cha "malo ananyema", otchedwa "malo ananyema", si okonzeka ndi ABS dongosolo odana loko pa galimoto ndi artificially kuponda pa discontinuous ananyema ntchito yonyamulira, kotero kuti gudumu braking mphamvu nthawi zina ayi, kuti 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 kwenikweni akhoza kuchita kudziwika chizindikiro 10 ~ 30 nthawi/sekondi, chiwerengero cha braking 70 ~ 150 nthawi / wachiwiri kuphedwa pafupipafupi, maganizo amenewa ndi kuphedwa pafupipafupi n'zosatheka kufika.
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.
