Ulayini wenzwa wangaphambili we-ABS
Inzwa ye-abs isetshenziswa ku-ABS (Anti-lock Braking System) yemoto.Iningi lohlelo lwe-ABS lugadwa yinzwa yokungenisa inductive ukuqapha isivinini semoto.Inzwa ye-abs ikhipha isethi enembile I-frequency kanye ne-amplitude yesiginali yamanje eshintshayo ye-sinusoidal ihlobene nesivinini sesondo.Isignali yokuphumayo idluliselwa ku-ABS electronic control unit (ECU) ukubona ukuqapha kwesikhathi sangempela kwesivinini sesondo.
izinhlobo eziyinhloko
1. Inzwa yejubane lesondo elingumugqa
Inzwa yesivinini samasondo ewumugqa ikakhulukazi yakhiwe uzibuthe ongapheli, i-pole shaft, ikhoyili yokungeniswa kanye negiya lendandatho.Lapho igiya lendandatho lizungeza, iziqongo zamazinyo nama-backlashes abhekana ne-axis ye-polar ngokushintshana.Ngesikhathi sokuzungezisa kwegiya lendandatho, ukugeleza kazibuthe ngaphakathi kwekhoyili yokungeniswa kuyashintsha ngokushintshana ukuze kukhiqize amandla e-electromotive, futhi le siginali ifakwa kuyunithi yokulawula kagesi ye-ABS ngekhebula ekugcineni kwekhoyili yokungeniswa.Lapho ijubane legiya lendandatho lishintsha, imvamisa yamandla e-electromotive eyenzelwe nawo ayashintsha.
2. Inzwa yejubane eliyindandatho
Inzwa yejubane lesondo le-annular ikakhulukazi yakhiwe uzibuthe ongapheli, ikhoyili yokungeniswa kanye negiya lendandatho.Umazibuthe unomphela wakhiwe ngamapheya amaningana ezigxobo kazibuthe.Ngesikhathi sokuzungezisa kwegiya lendandatho, ukugeleza kazibuthe ngaphakathi kwekhoyili yokungeniswa kuyashintsha ngokushintshana ukuze kukhiqize amandla e-electromotive akhangwe.Lesi siginali sifakwa kuyunithi yokulawula ye-elekthronikhi ye-ABS ngekhebula ekugcineni kwekhoyili yokungeniswa.Lapho ijubane legiya lendandatho lishintsha, imvamisa yamandla e-electromotive eyengelwe nawo ayashintsha.
3. Inzwa yejubane lesondo lehholo
Uma igiya lisendaweni eboniswe kokuthi (a), imigqa yamandla kazibuthe edlula engxenyeni yeHholo iyahlakazeka, futhi indawo kazibuthe ibuthakathaka ngokuqhathaniswa;kuyilapho lapho igiya lisendaweni eboniswe kokuthi (b), imigqa yamandla kazibuthe edlula engxenyeni yeHholo igxilile, futhi indawo kazibuthe inamandla ngokuqhathaniswa .Lapho igiya lizungeza, ukuminyana kokuguquguquka kazibuthe okudlula endaweni yeHholo kuyashintsha, ngaleyo ndlela kubangele ushintsho kugesi waseHholo, futhi isici seHholo sizokhipha i-quasi-sine wave voltage yeleveli ye-millivolt (mV).Lesi siginali sidinga futhi ukuguqulelwa ku-voltage ye-pulse ejwayelekile yisekethe ye-elekthronikhi.
Faka Hlela Ukusakaza
(1) Igiya lendandatho yokunyathela
Igiya lendandatho nendandatho yangaphakathi noma i-mandrel yeyunithi yehabhu isebenzisa ukulingana kokuphazanyiswa.Ngesikhathi somhlangano weyunithi yehabhu, igiya lendandatho kanye nendandatho yangaphakathi noma i-mandrel ihlanganiswa ndawonye ngomshini wokunyathelisa we-hydraulic;
(2) Faka inzwa
Kunezindlela ezimbili zokubambisana phakathi kwenzwa neringi yangaphandle yeyunithi yehabhu: ukulingana kokuphazamiseka nokukhiya amantongomane.Inzwa yejubane lesondo elilinganayo ikakhulukazi isesimweni sokukhiya amantongomane, futhi inzwa yejubane lesondo le-annular ithatha ukulingana kokuphazanyiswa;
Ibanga phakathi kwendawo yangaphakathi kazibuthe unomphela kanye nezinyo legiya lendandatho: 0.5±0.15mm (ikakhulukazi liqinisekiswa ngokulawula ububanzi bangaphandle begiya lendandatho, ububanzi bangaphakathi benzwa kanye nokugxila)
(3) I-voltage yokuhlola Sebenzisa i-voltage ephumayo ephrofeshinali ezenzele yona kanye ne-waveform ngesivinini esithile, futhi uhlole ukuthi ingabe kukhona isifunda esifushane senzwa yomugqa;
Isivinini: 900rpm
Isidingo sikagesi: 5. 3～7.9v
Izidingo ze-Waveform: igagasi le-sine elizinzile
ukutholwa kwamandla kagesi
Ukutholwa kwamandla kagesi okukhiphayo
Izinto zokuhlola:
1. Amandla kagesi okukhiphayo: 650～850mv(1 20rpm)
2. Umphumela we-waveform: i-sine wave ezinzile
Okwesibili, ukuhlolwa kokuqina kwezinga lokushisa eliphansi le-abs sensor
Gcina inzwa iku-40°C amahora angu-24 ukuze uhlole ukuthi inzwa ye-abs isengakwazi yini ukuhlangabezana nezimfuneko zokusebenza zikagesi nokuvala ukuze zisetshenziswe okuvamile.
