Umgca we-sensor ye-ABS yangaphambili
I-abs sensor isetyenziswa kwi-ABS (Anti-lock Braking System) yesithuthi. Uninzi lwenkqubo ye-ABS lujongwa yi-inductive sensor ukujonga isantya sesithuthi. I-abs sensor ikhupha iseti echanekileyo. Ubuninzi kunye nobukhulu besignali ye-sinusoidal alternating current zihambelana nesantya sevili. Isignali yokuphuma idluliselwa kwiyunithi yolawulo lwe-elektroniki ye-ABS (ECU) ukuze kujongwe isantya sevili ngexesha langempela.
iintlobo eziphambili
1. Inzwa yesantya sevili elihambayo
I-sensor yesantya sevili elithe tyaba yenziwe ikakhulu yimagnethi esisigxina, i-pole shaft, i-induction coil kunye ne-ring gear. Xa i-ring gear ijikeleza, ii-tooth top kunye ne-backlashes zijongana ne-polar axis ngokutshintshana. Ngexesha lokujikeleza kwe-ring gear, i-magnetic flux ngaphakathi kwe-induction coil iyatshintshana ukuze ivelise i-induced electromotive force, kwaye esi siginali singena kwi-ABS electronic control unit ngentambo ekupheleni kwe-induction coil. Xa isantya se-ring gear sitshintsha, i-frequency ye-induced electromotive force nayo iyatshintsha.
2. Isixhobo sokuvavanya isantya sevili elijikelezayo
I-annular wheel speed sensor yenziwe kakhulu yimagnethi esisigxina, i-induction coil kunye ne-ring gear. Imagnethi esisigxina yenziwe ngeepali ezininzi ze-magnetic poles. Ngexesha lokujikeleza kwegiya yeringi, i-magnetic flux ngaphakathi kwe-induction coil iyatshintsha ngokutshintshana ukuze ivelise amandla e-electromotive ashukunyiswayo. Esi siginali singena kwiyunithi yolawulo lwe-elektroniki ye-ABS ngentambo ekupheleni kwe-induction coil. Xa isantya segiya yeringi sitshintsha, i-frequency yamandla e-electromotive ashukunyiswayo nayo iyatshintsha.
3. Isixhobo sokuvavanya isantya sevili leHolo
Xa igiya ikwindawo eboniswe ku-(a), imigca yamandla emagnethi edlula kwi-Hall element iyasasazeka, kwaye i-magnetic field ibuthathaka; ngelixa xa igiya ikwindawo eboniswe ku-(b), imigca yamandla emagnethi edlula kwi-Hall element ixinene, kwaye i-magnetic field inamandla kakhulu. Xa igiya ijikeleza, uxinano lwe-magnetic flux edlula kwi-Hall element luyatshintsha, ngaloo ndlela kubangele utshintsho kwi-Hall voltage, kwaye i-Hall element iya kukhupha i-quasi-sine wave voltage ye-millivolt (mV) level. Esi siginali kufuneka siguqulwe sibe yi-standard pulse voltage yi-electronic circuit.
Faka i-Edit Broadcast
(1) Izixhobo zeringi yokunyathela
I-ring gear kunye ne-inner ring okanye i-mandrel ye-hub unit zihambelana nokuphazamiseka. Ngexesha lenkqubo yokuhlanganiswa kwe-hub unit, i-ring gear kunye ne-inner ring okanye i-mandrel zidityaniswe kunye nge-hydraulic press;
(2) Faka i-sensor
Kukho iindlela ezimbini zokusebenzisana phakathi kwesensor kunye neringi engaphandle yeyunithi yehabhu: ukulingana kokuphazamiseka kunye nokutshixa kwenati. Isensor yesantya sevili esithe ngqo ikakhulu ikwimo yokutshixa kwenati, kwaye isensor yesantya sevili esithe nkqo isebenzisa ukulingana kokuphazamiseka;
Umgama phakathi komphezulu wangaphakathi wemagnethi esisigxina kunye nomphezulu wezinyo wegiya yeringi: 0.5±0.15mm (uqinisekiswa kakhulu ngokulawula ububanzi bangaphandle begiya yeringi, ububanzi bangaphakathi besensor kunye nokuqina kwayo)
(3) Vavanya i-voltage Sebenzisa i-voltage yokuvelisa yobungcali kunye ne-waveform eyenziwe ngokwakho ngesantya esithile, kwaye uvavanye ukuba kukho i-short circuit ye-linear sensor;
Isantya: 900rpm
Imfuneko yeVolthi: 5. 3～7. 9v
Iimfuno zefomu yamaza: i-sine wave ezinzileyo
ukufunyanwa kwe-voltage
Ukufunyanwa kwe-voltage yemveliso
Izinto zovavanyo:
1. I-voltage yokuphuma: 650 ～850mv (1 20rpm)
2. Ifomu ye-waveform: i-sine wave ezinzileyo
Okwesibini, uvavanyo lokuqina kobushushu obuphantsi lwe-abs sensor
Gcina isensa kwi-40°C kangangeeyure ezingama-24 ukujonga ukuba isensa yesisu isakwazi na ukuhlangabezana neemfuno zokusebenza kombane kunye nokutywina ukuze isetyenziswe ngokuqhelekileyo.
