Kodi sensa ya ABS yakumbuyo ya galimoto ndi chiyani?
Sensa ya ABS yakumbuyo, yomwe imadziwikanso kuti sensa ya anti-lock braking system ya mawilo akumbuyo, ndi gawo lofunika kwambiri la dongosolo la anti-lock braking la galimoto (ABS), lomwe limapangidwira makamaka kuyang'anira liwiro lozungulira la mawilo akumbuyo.
Ntchito yake yaikulu ndi kutumiza zambiri zenizeni zokhudza liwiro la gudumu lakumbuyo ku chipangizo chowongolera chamagetsi cha ABS (ECU) cha galimotoyo. Galimotoyo ikakhala pamalo oterera kapena panthawi ya braking yadzidzidzi, ngati mawilo akumbuyo atsala pang'ono kutseka (ndi kuchepa kwakukulu kwa liwiro lozungulira), dongosolo la ABS, kutengera deta yoperekedwa ndi sensa iyi, lidzasintha mwachangu mphamvu ya braking ya mawilo akumbuyo kuti asatsekedwe kwathunthu, motero kuonetsetsa kuti galimotoyo ikusunga kukhazikika kwa kayendetsedwe kake ndi kayendetsedwe kake panthawi ya braking ndikupewa kutsetsereka kapena kusodza nsomba.
Zinthu zazikulu ndi mfundo yogwirira ntchito
Malo oyika: Kawirikawiri amakhala pafupi ndi malo olumikizira mawilo akumbuyo, pafupi ndi brake disc kapena mphete yamkati ya mpando wolumikizira mawilo akumbuyo, ndi mpata wochepa kwambiri (pafupifupi 0.3-1.0mm) pakati pa mapeto ozindikira ndi mphete ya giya (kapena mphete yolumikizira magiya) yomwe imazungulira mogwirizana ndi gudumu lakumbuyo.
Mfundo yogwirira ntchito: Kudzera mu induction yamagetsi kapena Hall effect, sensa imazindikira kuchuluka kwa mano ndi mipata yomwe imadutsa pa mphete ya giya, ndikupanga chizindikiro chamagetsi chosinthika chofanana ndi liwiro lozungulira la gudumu lakumbuyo (magnetic-electric output sine wave, Hall output square wave), chomwe chimatumizidwa kudzera mu waya wolumikizira ku gawo lowongolera la ABS.
Kulumikizana kwa makina: Deta yochokera ku sensa ya ABS yakumbuyo siigwiritsidwa ntchito ndi makina a ABS okha komanso nthawi zambiri imagawidwa ndi makina ena oteteza monga ESP (dongosolo lokhazikika kwa magalimoto) ndi TCS (dongosolo lowongolera mphamvu), zomwe zimagwiritsidwa ntchito ngati gwero lofunikira la kayendetsedwe ka mphamvu ka galimoto.
Kuwonongeka ndi kukonza zolakwika
Zizindikiro zofala za vuto: Pamene sensa ya ABS yakumbuyo yalephera kapena chizindikiro sichikuyenda bwino, nyali ya ABS/ESP pa dashboard imakhalabe yoyaka kapena yowala, zomwe zingayambitse kuti mawilo akumbuyo azitseka panthawi ya braking yadzidzidzi, zomwe zimapangitsa kuti mtunda wa braking ukhale wotalikirapo, makamaka pamisewu yoterera yomwe ili ndi chiopsezo chachikulu.
Malangizo okonza: Nthawi zonse onani ngati sensa ndi yodetsedwa, yowonongeka, kapena ngati chingwe cholumikizira waya chawonongeka; pewani kuwononga mawaya mukamasintha matayala; ngati sensayo yalumikizidwa mu hub bearing (monga momwe zilili ndi mitundu ina ya Audi ndi BMW), kuwonongeka kumafuna kusintha gawo lonse la hub bearing.
Sensa ya ABS yakumbuyo (monga sensa ya liwiro la gudumu lakumbuyo) ndi gawo lofunika kwambiri la dongosolo la mabuleki loletsa kutseka (ABS) la galimoto, ndipo ntchito yake yayikulu ndikuwunika liwiro lozungulira la magudumu akumbuyo nthawi yeniyeni ndikutumiza detayo ku chipangizo chowongolera zamagetsi cha galimoto (ECU) kuti zitsimikizire kukhazikika komanso chitetezo panthawi yoletsa mabuleki.
Ntchito zenizeni zitha kufotokozedwa mwachidule motere:
Ntchito yaikulu: Kuteteza kutsekedwa kwa gudumu lakumbuyo, kuonetsetsa kuti mabuleki ali olimba
Kuwunika liwiro nthawi yeniyeni: Sensa, kudzera mu kuzungulira kogwirizana ndi mphete ya giya yomwe yayikidwa pa hub ya gudumu lakumbuyo, imapanga chizindikiro chogwirizana ndi liwiro la gudumu (monga mafunde a sine kapena chizindikiro cha pulse), zomwe zimapereka mayankho nthawi zonse pa momwe gudumu likuzungulira.
Kuletsa kutsekeka: Pa nthawi ya braking yadzidzidzi, ngati liwiro lozungulira la mawilo akumbuyo latsika kwambiri (kusonyeza kuti pali chizolowezi chotsekeka), sensa imatumiza chizindikiro nthawi yomweyo ku ABS control module. Kenako module imalangiza valavu yamagetsi kuti ichepetse mphamvu yotsekeka ya gudumulo. Izi zimaletsa mawilo kuti asatsekeke kwathunthu, zomwe zimathandiza kuti matayala azikhala bwino ngati "akutsetsereka" (chiŵerengero chotsetsereka pafupifupi 20%), potero:
Kuchepetsa mtunda woyimitsa mabuleki: Kugwiritsa ntchito kugwedezeka kosasinthasintha m'malo mosuntha kugwedezeka, kumapangitsa kuti mabuleki azigwira bwino ntchito.
Kupewa kutsetsereka ndi kugubuduzika: Makamaka m'misewu yoterera kapena panthawi yopewera mwadzidzidzi, kupewa kutayika kwa kumbuyo kwa galimoto, kutsetsereka, kapena kuzungulira.
Kusunga chiwongolero chowongolera: Kuonetsetsa kuti dalaivala akuwongolera bwino komwe akupita panthawi yotseka mabuleki, zomwe zimathandiza kupewa ngozi.
Ntchito yothandizira: Kuthandizira machitidwe ena otetezera magalimoto
Deta yochokera ku sensa ya ABS yakumbuyo siigwiritsidwa ntchito ndi ABS yokha komanso imagawidwa ndi makina ambiri amagetsi, zomwe zimapangitsa kuti pakhale kuphatikizana kwa ntchito zambiri:
Kuzindikira liwiro: Chizindikiro chosonyeza liwiro la magalimoto ambiri chimachokera mwachindunji ku sensa ya liwiro la mawilo akumbuyo, zomwe zimapereka chidziwitso cholondola cha liwiro ku dashboard. Kuwunika Kupanikizika kwa Matayala Mosalunjika (TPMS): Poyerekeza kusiyana kwa liwiro la mawilo anayi, ngati liwiro la mawilo akumbuyo ndi losazolowereka (monga kuthamanga pang'ono kwa matayala komwe kumayambitsa kugwedezeka kochepa), dongosololi lingathe kudziwa kuthamanga kwa matayala molakwika ndikuyambitsa alamu.
Kuwongolera Kukhazikika kwa Thupi (ESC/ESP): Kumapereka deta ya liwiro la gudumu lakumbuyo la pulogalamu yokhazikika yamagetsi, kuthandiza kudziwa ngati galimotoyo yatsika kapena ili ndi chiwongolero chosakwanira kapena chokwera kwambiri, motero kulowererapo mwachangu pakuletsa mabuleki ndi mphamvu.
Kuwongolera Kugwira Ntchito (TCS): Kumayang'anira ngati mawilo akumbuyo akutsetsereka panthawi yothamanga, ndikusinthira mphamvu yotulutsa yokha kuti mawilo oyendetsa asazungulire.
Ntchito zina za magalimoto enaake: Mu magalimoto monga Volkswagen ndi Audi, masensa amathanso kuzindikira kusintha kwa mawilo akumbuyo kuti aone ngati zomangira za matayala zili zotayirira, ndikuyambitsa machenjezo ofanana.
Zotsatira za zolakwika
Ngati sensa ya ABS yakumbuyo yawonongeka kapena chizindikiro sichikuyenda bwino, izi zimabweretsa:
Nyali ya ABS, nyali ya ESC/ESP kapena nyali ya kuthamanga kwa tayala idzaunikira.
Kulephera kwa dongosolo la ABS: Pa nthawi ya braking yadzidzidzi, mawilo akumbuyo amatha kutsekedwa, zomwe zimawonjezera chiopsezo chotsetsereka.
Makina ena amatsitsa liwiro: Kuwonetsa liwiro la galimoto kungakhale kolakwika, kuyang'anira kuthamanga kwa matayala kungalephereke, ndipo kugwira ntchito bwino kwa thupi kungakhale kochepa.
Mwachidule, ngakhale kuti sensa ya ABS yakumbuyo ndi yaying'ono, ndi "chiwalo chowunikira" chomwe chimatsimikizira chitetezo cha mabuleki, kukhazikika komanso kugwira ntchito mwanzeru kwa galimotoyo.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
