Chii chinonzi Rear ABS Sensor? Ndeapi marudzi aripo uye anoiswa sei?
Sensor ye abs inoshandiswa mumota ye ABS (Anti-lock Braking System). MuABS system, kumhanya kunotariswa ne inductive sensor. Sensor ye abs inoburitsa seti yemasaini emagetsi e AC quasi-sinusoidal kuburikidza nekushanda kwegiya rinotenderera pamwe chete nevhiri, uye frequency yaro uye amplitude zvine chekuita nekumhanya kwevhiri. Chiratidzo chekubuda chinotumirwa kuABS electronic control unit (ECU) kuti chionekwe nekukurumidza kwevhiri panguva chaiyo.
1, sensor yekumhanya kwevhiri rakatsetseka
Sensor yekumhanya kwevhiri remagetsi inoumbwa zvakanyanya nemagneti inogara iripo, pole axis, induction coil uye tooth ring. Kana giya rinotenderera, muromo wegiya nebacklash zvinochinjana zvakapesana ne polar axis. Munguva yekutenderera kwegiya rinotenderera, magnetic flux iri mukati me induction coil inoshanduka ichichinjana kuti igadzire induction electromotive force, uye chiratidzo ichi chinopinzwa ku electronic control unit yeABS kuburikidza netambo iri kumagumo kwe induction coil. Kana kumhanya kwegiya rinoshanduka, frequency ye induced electromotive force inochinjawo.
2, sensor yekumhanya kwevhiri remhete
Sensor yekumhanya kwevhiri reAnnular inonyanya kugadzirwa nemagneti inogara iripo, induction coil uye tooth ring. Magineti inogara iripo inoumbwa nemapaya akati wandei emagineti. Panguva yekutenderera kwegiya regiya, magnetic flux iri mukati meinduction coil inoshanduka ichichinjana kuti igadzire induction electromotive force. Chiratidzo ichi chinopinzwa kuyuniti yekudzora yemagetsi yeABS kuburikidza netambo iri kumagumo kweinduction coil. Kana kumhanya kwegiya regiya kuchichinja, frequency yeinduced electromotive force inochinjawo.
3, sensor yekumhanya kwevhiri remhando yeHoro
Kana giya riri panzvimbo inoratidzwa mu (a), mitsetse yesimba remagineti inopfuura nepakati pechinhu cheHall inopararira uye simba remagineti harina kusimba; Kana giya riri panzvimbo inoratidzwa mu (b), mitsetse yesimba remagineti inopfuura nepakati pechinhu cheHall inounganidzwa uye simba remagineti rakasimba. Kana giya richitenderera, huwandu hwesimba remagineti rinopfuura nepakati pechinhu cheHall hunochinja, izvo zvinoita kuti voltage yeHall ichinje, uye chinhu cheHall chinoburitsa millivolt (mV) level ye quasi-sine wave voltage. Chiratidzo ichi chinofanirawo kushandurwa ne electronic circuit kuita standard pulse voltage.
Isa
(1) Mhete yegiya rekutsika
Mhete yemazino nemhete yemukati kana mandrel yehub unit zvinopindirana. Pakuungana kwehub unit, mhete yemazino nemhete yemukati kana mandrel zvinosanganiswa pamwe chete nekudzvanya mafuta.
(2) Isa sensor
Kubatana pakati pesensa neringi yekunze yehub unit ndiko kupindirana kwemukati uye kukiya kwenati. Sensa yekumhanya kwevhiri yakatsetseka inonyanya kuumbwa sechivharo chenati, uye sensa yekumhanya kwevhiri reringi inoshandisa kupindirana kwemukati.
Kureba pakati pepamusoro pemagineti anogara kwenguva refu nepamusoro pezino remhete: 0.5 ± 0.15 mm (kunyanya kuburikidza nekudzora dhayamita yekunze yemhete, dhayamita yemukati yesensor uye concentricity)
(3) Voltage yekuyedza inoshandisa voltage yekuburitsa yehunyanzvi yakagadzirwa yega uye waveform pane imwe nhanho, uye sensor yemutsara inofanirawo kuyedza kana short circuit iri;
Kumhanya: 900rpm
Kudiwa kwemagetsi: 5.3 ~ 7.9 V
Zvinodiwa pakuita mafungu: sine wave yakagadzikana
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa MGZvikamu zvemota zve &MAUXS zvinogamuchirwa kutenga.
