Sensa ya ABS, makina oletsa kutsekeka kwa mabuleki.
Mitundu ikuluikulu
1, sensa yothamanga ya gudumu lolunjika
Sensa yothamanga ya mawilo a mzere imapangidwa makamaka ndi maginito okhazikika, pole axis, induction coil ndi tooth ring. Pamene giya likuzungulira, nsonga ya giya ndi backlash zimasinthasintha motsatizana ndi polar axis. Panthawi yozungulira giya, maginito mkati mwa induction coil amasintha motsatizana kuti apange induction electromotive force, ndipo chizindikirochi chimalowetsedwa ku electronic control unit ya ABS kudzera mu chingwe kumapeto kwa induction coil. Pamene liwiro la giya likusinthasintha, kuchuluka kwa mphamvu yoyendetsera electromotive yomwe yayambitsidwa kumasinthanso.
2, sensa ya liwiro la gudumu lozungulira
Sensa yothamanga ya mawilo angular imapangidwa makamaka ndi maginito okhazikika, cholumikizira cha induction ndi mphete ya dzino. Maginito okhazikika amapangidwa ndi mapeyala angapo a maginito. Pakuzungulira kwa mphete ya giya, mphamvu ya maginito mkati mwa cholumikizira cha induction imasintha mosinthana kuti ipange mphamvu ya induction electromotive. Chizindikiro ichi chimalowetsedwa ku chipangizo chowongolera zamagetsi cha ABS kudzera mu chingwe chomwe chili kumapeto kwa cholumikizira cha induction. Pamene liwiro la mphete ya giya lisintha, kuchuluka kwa mphamvu ya electromotive yomwe imayambitsa imasinthanso.
3, Sensor ya liwiro la gudumu la mtundu wa Hall
Giya ikapezeka pamalo omwe akuwonetsedwa mu (a), mizere ya maginito yomwe imadutsa mu Hall element imafalikira ndipo mphamvu ya maginito imakhala yofooka; Giya ikapezeka pamalo omwe akuwonetsedwa mu (b), mizere ya maginito yomwe imadutsa mu Hall element imakhala yokhazikika ndipo mphamvu ya maginito imakhala yamphamvu. Giya ikazungulira, kuchuluka kwa mphamvu ya maginito yomwe imadutsa mu Hall element kumasintha, zomwe zimapangitsa kuti mphamvu ya Hall isinthe, ndipo gawo la Hall limatulutsa mulingo wa millivolt (mV) wa quasi-sine wave voltage. Chizindikiro ichi chimafunikanso kusinthidwa ndi electronic circuit kukhala voltage yokhazikika ya pulse.
Ikani
(1) Mphete yopondera zida
Mphete ya dzino ndi mphete yamkati kapena mandrel ya hub unit zimakhala ndi kusakanikirana koyenera. Pogwirizanitsa hub unit, mphete ya dzino ndi mphete yamkati kapena mandrel zimagwirizanitsidwa pamodzi pogwiritsa ntchito mafuta.
(2) Ikani sensa
Kugwirizana pakati pa sensa ndi mphete yakunja ya hub unit ndi kulowererana pakati pa kulowererana ndi kutsekeka kwa nati. Sensa ya liwiro la gudumu lolunjika makamaka imakhala yofanana ndi loko la nati, ndipo sensa ya liwiro la gudumu lozungulira imagwiritsa ntchito kulowererana pakati pa kulowererana.
Mtunda pakati pa pamwamba pa maginito okhazikika ndi pamwamba pa dzino la mphete: 0.5 ± 0.15 mm (makamaka kudzera mu ulamuliro wa m'mimba mwake wakunja wa mphete, m'mimba mwake wamkati wa sensa ndi concentricity)
(3) Voltage yoyesera imagwiritsa ntchito voteji yotulutsa yaukadaulo yodzipangira yokha ndi mawonekedwe a waveform pa liwiro linalake, ndipo sensa yolunjika iyeneranso kuyesa ngati dera lalifupi ndi lolondola;
Liwiro: 900rpm
Kufunika kwa magetsi: 5.3 ~ 7.9 V
Zofunikira pa mawonekedwe a waveform: mafunde olimba a sine
Kuzindikira mphamvu yamagetsi
Kuzindikira kwa voteji yotuluka
Zinthu zowunikira:
1, voteji yotulutsa: 650 ~ 850mv (1 20rpm)
2, mawonekedwe a mafunde otuluka: mafunde okhazikika a sine
Chachiwiri, mayeso okhazikika a sensor ya abs
Sungani sensa pa 40 ° C kwa maola 24 kuti muyese ngati sensa ya abs ikhoza kukwaniritsa zofunikira zamagetsi ndi kutseka zomwe zimagwiritsidwa ntchito mwachizolowezi.
Kodi sensa ya m'mimba ikutsogolo ndi kumbuyo?
Sensa ya ABS ili kumanzere ndi kumanja. Sensa ya ABS ndi gawo lofunika kwambiri la dongosolo la mabuleki oletsa kutseka magalimoto, lomwe limagwiritsidwa ntchito kuzindikira liwiro la mawilo ndikulitumiza ku gawo lowongolera la ABS. Mwanjira imeneyi, gawo lowongolera limatha kusintha kukula kwa mphamvu ya mabuleki malinga ndi liwiro ndi liwiro la gudumu kuti gudumu lisatsekedwe. Masensa a ABS nthawi zambiri amaikidwa m'malo pafupi ndi mawilo, omwe amatha kusiyana malinga ndi mtundu ndi mtundu. Kwa mitundu monga Volkswagen Lavida, sensa ya ABS imayikidwa padera malinga ndi gudumu lililonse, zonse zinayi kutsogolo ndi kumbuyo kumanzere ndi kumanja. Izi zikutanthauza kuti sensa ya ABS ili ndi malo akumanzere ndi kumanja pa gudumu lakutsogolo la galimoto, kotero ndikofunikira kusiyanitsa pakati pa kumanzere ndi kumanja. Mwachitsanzo, ngati sensa ya gudumu lakumanzere yawonongeka mukasintha sensa ya ABS, muyenera kuyisintha moyenera.
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zikulandiridwa kugula.
