Mukudziwa chiyani za sensor ya ABS?

M'moyo anthu ambiri amatha kuyendetsa, ndipo anthu ambiri amadziwa za Anti-lock Braking System(ABS), koma ndi anthu angati omwe amadziwa bwino za masensa a ABS?

Sensa ya ABS imagwiritsidwa ntchito mu ABS yamagalimoto.Mu dongosolo la ABS, masensa inductive amagwiritsidwa ntchito kuwunika kuthamanga kwagalimoto.Sensa ya ABS imatulutsa ma quasi-sinusoidal alternating alternating signals apano kudzera mumayendedwe a mphete yomwe imazungulira ndi mawilo.Mafupipafupi ndi matalikidwe amagwirizana ndi liwiro la gudumu.Chizindikiro chotuluka chimatumizidwa ku ABS electronic control unit (ECU) kuti muzindikire kuwunika kwenikweni kwa liwiro la gudumu.

Mitundu yayikulu

Linear wheel speed sensor

Sensa yothamanga yama wheel wheel imapangidwa makamaka ndi maginito okhazikika, ma pole shaft, ma coil olowetsa ndi ma giya a mphete.Pamene mphete imazungulira, nsonga ya dzino ndi kusiyana kwa dzino zimatsutsana ndi polar axis.Panthawi yozungulira giya la mphete, kusinthasintha kwa maginito mkati mwa coil induction kumapangitsanso mphamvu ya electromotive.Chizindikirochi chimalowetsedwa ku gawo lowongolera zamagetsi la ABS kudzera pa chingwe kumapeto kwa koyilo yolowera.Liwiro la giya la mphete likasintha, ma frequency a induced electromotive force amasinthanso.

Sensor yothamanga ya ring wheel

Sensa yothamanga ya ring wheel imapangidwa makamaka ndi maginito osatha, ma coil induction ndi ma giya a mphete.Maginito okhazikika amapangidwa ndi mapeyala angapo amitengo yamaginito.Panthawi yozungulira giya la mphete, kusinthasintha kwa maginito mkati mwa coil induction kumapangitsanso mphamvu ya electromotive.Chizindikirochi chimalowetsedwa ku gawo lowongolera zamagetsi la ABS kudzera pa chingwe kumapeto kwa koyilo yolowera.Liwiro la giya la mphete likasintha, ma frequency a induced electromotive force amasinthanso.

Hall mtundu wa wheel speed sensor

Geya ikazungulira, kachulukidwe ka maginito odutsa mu Hall amasintha, zomwe zimapangitsa kuti magetsi a Hall asinthe.The Hall element itulutsa mphamvu ya millivolt (mV) quasi-sine wave voltage.Chizindikirochi chimafunikanso kusinthidwa kukhala voteji yokhazikika ndi dera lamagetsi.

Sensa ya ABS ndi gawo lofunikira la dongosolo la ABS.ABS imatha kupatsa mphamvu mabuleki poyendetsa galimoto, kufupikitsa mtunda wothamanga, kuteteza bwino kutsekeka kapena kutsekeka kwa tayala panthawi ya braking mwadzidzidzi, kukulitsa kukhazikika kwagalimoto ndikuwonjezera chiwongolero chagalimoto, Itha kupewa kukangana kwamphamvu pakati pawo. tayala ndi nthaka, kuchepetsa kugwiritsa ntchito matayala ndi kutalikitsa moyo utumiki wa tayala.

Ndiye mumadziwa zambiri za sensor ya ABS?Takulandilani kuti mulumikizane ndi fakitale yathu ya VM sensor!
