Kodi anti-lock braking system kapena ABS ndi chiyani?
Zamkatimu
Kuponderezedwa kwadzidzidzi kwa brake pedal mumikhalidwe yonyowa kapena yachisanu kumapangitsa kuti magudumu agalimoto atsekedwe ndipo matayala amalephera kugwira pamsewu. Chotsatira chake, galimotoyo sikuti imangoyenda pang'onopang'ono, komanso imataya mphamvu, zomwe zimayambitsa ngozi. Zikatero, madalaivala akatswiri amagwiritsa ntchito intermittent braking njira, amene amakulolani kuchepetsa liwiro la galimoto ndi kusunga mawilo ndi msewu.
Sikuti oyendetsa galimoto onse amatha kukhala odziletsa pakachitika ngozi komanso kuyankha pamavuto amsewu. Chifukwa chake, kuti musatseke mawilo oyendetsa pamagalimoto, magalimoto ali ndi anti-lock braking system kapena ABS. Ntchito yayikulu ya ABS ndikusunga malo okhazikika agalimoto munjira yonse yowotchera ndikuchepetsa kutalika kwake kukhala kochepa.
Masiku ano, dongosololi limayikidwa pafupifupi magalimoto onse, ngakhale pamakonzedwe oyambira, osatchulanso matembenuzidwe apamwamba. Zosintha zoyamba za anti-lock braking system zidawonekera m'zaka za m'ma 1970, inali imodzi mwazosankha pakuwongolera chitetezo chagalimoto.
Chipangizo cha ABS
Anti-lock braking system ili ndi midadada itatu:
- liwiro sensa (wokwera pa gudumu hubs ndipo amakulolani molondola chiyambi cha braking);
- ma valve owongolera (kuwongolera kuthamanga kwamadzimadzi a brake);
- Electronic microprocessor unit (imagwira ntchito motengera ma siginecha ochokera ku masensa othamanga ndikutumiza kukakamiza kuti iwonjezere / kuchepetsa kupanikizika kwa mavavu).
Njira yolandirira ndi kutumiza deta kudzera pamagetsi amagetsi imachitika pafupipafupi ka 20 pamphindikati.
Mfundo yofunikira ya anti-lock braking system
Kutalika kwa braking ndiye vuto lalikulu m'nyengo yozizira yogwira ntchito yagalimoto kapena pamsewu wokhala ndi mvula. Anthu akhala akudziŵika kwa nthawi yaitali kuti pomanga mabuleki okhala ndi mawilo okhoma, mtunda woyima umakhala wautali kuposa kuboma ndi mawilo opota. Ndi dalaivala wodziwa bwino yekha amene angamve kuti chifukwa cha kupanikizika kwambiri pa brake pedal, mawilo amatsekedwa ndipo, poyendetsa pang'ono pedal, amasintha kupanikizika kwake. Komabe, izi sizikutanthauza kuti kuthamanga kwa brake kugawika kwa mawilo oyendetsa molingana ndi zofunikira.
Anti-lock braking system idapangidwa kuti iziyang'anira kuzungulira kwa wheelbase. Ngati mwadzidzidzi atsekeka pamene akuwotcha, ABS imachepetsa kuthamanga kwa brake fluid kuti gudumu litembenuke, ndikumangiriranso kuthamanga. Ndi mfundo iyi ya ntchito ya ABS yomwe imapangitsa kuti pakhale "intermittent braking", yomwe imatengedwa kuti ndiyothandiza kwambiri kuchepetsa kutalika kwa mtunda wa braking pamtunda uliwonse.
Nthawi yomwe dalaivala akukankhira chopondapo, sensor yothamanga imazindikira loko ya gudumu. Chizindikirocho chimapita ku chipangizo chamagetsi, ndipo kuchokera kumeneko kupita ku ma valve. Kawirikawiri amagwira ntchito pa ma hydraulics, kotero atalandira chizindikiro choyamba cha chiyambi cha gudumu, valavu imachepetsa kutulutsa kwamadzimadzi kapena kulepheretsa kutuluka kwake. Motero, silinda ya brake imayimitsa ntchito yake mokwanira kuti gudumu litembenuke kamodzi kokha. Pambuyo pake, valavu imatsegula mwayi wamadzimadzi.
Zizindikiro zotulutsira ndi kuswanso gudumu lililonse zimaperekedwa mwanjira inayake, kotero kuti nthawi zina madalaivala amatha kumva kugwedezeka kwamphamvu komwe kumachitika pa brake pedal. Amawonetsa magwiridwe antchito apamwamba kwambiri a anti-lock braking system ndipo adzawonekera mpaka galimoto itayima kapena kuwopseza kutseka kwa mawilo kutha.
Kuchita kwa braking
Ntchito yayikulu ya anti-lock braking system sikuti ingochepetsa kutalika kwa mtunda wa braking, komanso kusunga chiwongolero cha dalaivala. Kuchita bwino kwa mabuleki a ABS kwatsimikiziridwa kale: galimotoyo situluka m'manja mwa dalaivala ngakhale mwadzidzidzi, mwadzidzidzi, ndipo mtunda wake ndi waufupi kwambiri kuposa woyendetsa bwino. Kuphatikiza apo, kutsika kwa matayala kumawonjezeka ngati galimotoyo ili ndi anti-lock braking system.
Ngakhale pa nthawi ya kukanikiza lakuthwa kwa ananyema pedal galimoto anali kuchita kuwongolera (mwachitsanzo, kutembenuka), controllability wonse adzakhala m'manja mwa dalaivala, zomwe zimapangitsa ABS dongosolo chimodzi mwa zinthu zofunika kwambiri. kukonza chitetezo chogwira ntchito chagalimoto.
FAVORIT MOTORS Gulu akatswiri amalangiza kuti oyendetsa novice kusankha magalimoto okhala ndi mabuleki thandizo dongosolo. Izi zidzalola ngakhale braking mwadzidzidzi ndi kukakamiza mwamphamvu pa pedal. ABS idzagwira ntchito yotsalayo yokha. Showroom ya FAVORIT MOTORS imapereka magalimoto ambiri omwe ali ndi ABS. Mukhoza kuyesa dongosololi likugwira ntchito polembetsa kuti muyese galimoto. Izi zikuthandizani kuti mufananize mphamvu yoyimitsa yagalimoto yokhala ndi ABS komanso popanda.
Ndikofunika kukumbukira kuti dongosolo limasonyeza ntchito yaikulu pokhapokha ndi kuyendetsa bwino kwa galimotoyo. Ngati mumayendetsa pa ayezi pa matayala a chilimwe, ndiye kuti mukamakwera mabuleki, ABS imangosokoneza. Kuonjezera apo, dongosololi limayankha pang'onopang'ono poyendetsa mchenga kapena matalala, pamene mawilo amamira pamtunda wosasunthika ndipo samakumana ndi kukana.
Masiku ano, magalimoto amapangidwa ndi machitidwe oletsa loko, omwe, ngati kuli kofunikira, akhoza kuzimitsidwa paokha.
ABS ntchito
Machitidwe onse amakono oletsa loko amaonedwa kuti ndi odalirika. Iwo akhoza kugwiritsidwa ntchito kwa nthawi yaitali. Magawo owongolera pamagetsi amalephera kapena kulephera kawirikawiri, popeza mainjiniya ochokera kwa opanga magalimoto otsogola amawakonzekeretsa ndi njira zotetezera.
Komabe, ABS ili ndi mfundo yofooka - masensa othamanga. Ichi ndi chifukwa chakuti iwo ali pa hubs moyandikana ndi mbali mozungulira. Chifukwa chake, masensa amatha kuipitsidwa komanso kupangika kwa ayezi. Kuphatikiza apo, kuchepetsedwa kwa voteji pama terminals a batri kumathanso kukhudza kwambiri magwiridwe antchito adongosolo. Mwachitsanzo, ngati voteji akutsikira pansi 10.5V, ABS mwina basi kuyatsa chifukwa chosowa mphamvu.
Ngati anti-lock braking system (kapena chinthu chake) sichikuyenda bwino, chizindikiro chofananira chidzayatsa pa gululo. Izi sizikutanthauza kuti galimotoyo idzakhala yosayendetsedwa bwino. Dongosolo la braking labwinobwino lipitiliza kugwira ntchito ngati pagalimoto yopanda ABS.
Akatswiri a FAVORIT MOTORS Group of Companies amachita zowunikira zovuta m'dongosolo ndikukonza kwathunthu zigawo zonse za ABS. Ntchito yamagalimoto imakhala ndi zida zonse zofunikira zowunikira komanso zida zopapatiza zomwe zimakulolani kuti mubwezeretse mwachangu komanso moyenera magwiridwe antchito a ABS pagalimoto yamtundu uliwonse ndi chaka chopangidwa.
