ABS sensor.
Abs sensor yog siv rau hauv lub tsheb tsav ABS (Anti-lock Braking System). Nyob rau hauv ABS system, qhov ceev yog saib xyuas los ntawm inductive sensor. Lub abs sensor outputs ib txheej ntawm quasi-sinusoidal AC hluav taws xob teeb liab los ntawm qhov kev txiav txim ntawm lub nplhaib iav uas tig synchronously nrog lub log, thiab nws zaus thiab amplitude muaj feem xyuam rau lub log ceev. Lub teeb liab tso zis tau xa mus rau ABS hluav taws xob tswj chav tsev (ECU) kom paub txog lub sijhawm saib xyuas lub log ceev.
1, linear log ceev sensor
Linear log ceev sensor yog tsim los ntawm cov hlau nplaum ruaj khov, ncej axis, induction coil thiab hniav nplhaib. Thaum lub iav nplhaib tig, lub hau ntawm lub iav thiab lub nraub qaum rov qab hloov qhov sib txawv ntawm cov polar axis. Thaum lub sij hawm kev sib hloov ntawm lub nplhaib iav, cov hlau nplaum sib nqus nyob rau hauv induction kauj hloov pauv los tsim cov induction electromotive quab yuam, thiab cov teeb liab no tau nkag mus rau hauv chav tswj hluav taws xob ntawm ABS los ntawm cov kab hauv qhov kawg ntawm induction kauj. Thaum qhov ceev ntawm lub nplhaib iav hloov, qhov zaus ntawm qhov induced electromotive quab yuam kuj hloov.
2, lub nplhaib log ceev sensor
Annular log ceev sensor yog tsim los ntawm cov hlau nplaum ruaj khov, induction coil thiab hniav nplhaib. Cov hlau nplaum ruaj khov yog tsim los ntawm ob peb khub ntawm cov hlau nplaum. Thaum lub sij hawm sib hloov ntawm lub nplhaib iav, cov hlau nplaum sib nqus hauv qhov induction coil hloov pauv los tsim cov induction electromotive quab yuam. Cov teeb liab no yog cov tswv yim nkag mus rau hauv chav tswj hluav taws xob ntawm ABS los ntawm lub cable ntawm qhov kawg ntawm induction coil. Thaum qhov ceev ntawm lub nplhaib iav hloov, qhov zaus ntawm qhov induced electromotive quab yuam kuj hloov.
3, Hall hom log ceev sensor
Thaum lub iav nyob rau hauv txoj hauj lwm qhia nyob rau hauv (a), cov kab hlau nplaum uas hla dhau lub Hall lub caij yog dispersed thiab lub magnetic teb kuj tsis muaj zog; Thaum lub iav nyob rau hauv txoj hauj lwm qhia nyob rau hauv (b), cov kab hlau nplaum uas hla dhau lub Hall lub ntsiab yog concentrated thiab lub magnetic teb kuj muaj zog. Thaum lub iav tig, qhov ceev ntawm cov kab hlau nplaum ntawm lub zog dhau los ntawm Hall element hloov, uas ua rau Hall voltage hloov, thiab Hall lub caij yuav tso tawm ib millivolt (mV) theem ntawm quasi-sine yoj voltage. Cov teeb liab no kuj yuav tsum tau hloov los ntawm cov hluav taws xob hluav taws xob mus rau hauv tus qauv pulse voltage.
Puas yog qhov tawg ntawm abs sensor cuam tshuam rau 4-tsav
Tej zaum
Kev puas tsuaj rau lub nraub qaum ABS tuaj yeem cuam tshuam rau tag nrho lub log tsav, tshwj xeeb tshaj yog tias txhua lub log tsav tau nruab nrog qhov sib txawv ntawm qhov sib txawv. Qhov no yog vim hais tias lub tsheb log sensor ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev sib tsoo braking system (ABS), ib zaug puas lawm, ABS system yuav tsis raug lees paub qhov ceev thiab cov xwm txheej ntawm lub log, uas cuam tshuam rau nws cov nyhuv braking, thiab tej zaum yuav ua rau muaj kev cuam tshuam. mus rau lub log xauv thaum lub sijhawm braking, ua rau muaj kev pheej hmoo ntawm kev tsav tsheb. Tsis tas li ntawd, yog tias lub tshuab hluav taws xob plaub-log tsav tau nruab nrog lub tshuab xauv qhov sib txawv, kev puas tsuaj rau lub log tsheb yuav ua rau qhov sib txawv ntawm lub xauv tsis ua haujlwm zoo, uas yuav cuam tshuam rau kev ua haujlwm ntawm plaub lub log tsav. Yog li ntawd, txawm hais tias qhov kev puas tsuaj ntawm lub log tsheb yuav tsis cuam tshuam ncaj qha rau kev ua haujlwm ntawm plaub lub log tsav, txhawm rau ua kom muaj kev nyab xeeb ntawm kev tsav tsheb, nws raug nquahu kom kho lossis hloov lub sensor puas hauv lub sijhawm.
ABS rear log sensor yuav ua tsis tau vim hnav. cov
ABS sensor tsis ua hauj lwm suav nrog ABS lub teeb ntawm lub dashboard, ABS tsis ua haujlwm zoo, thiab traction tswj lub teeb rau. Cov kev ua tsis tiav no tuaj yeem tshwm sim los ntawm cov sensors hnav tawm, txiav tawm, lossis raug ntaus los ntawm cov khib nyiab. Tshwj xeeb tshaj yog lub log tsheb ABS sensor, yog tias cov hlau nplaum tsim los ntawm kev sib tsoo ntawm lub nres nres thiab nres nres yog adsorbed los ntawm cov hlau nplaum, yuav ua rau qhov kev ncua deb ntawm lub sensor thiab cov hlau nplaum coil ua me me, lossis txawm hnav. , nws thiaj li ua rau lub sensor puas. cov
Txhawm rau txiav txim siab seb ABS sensor puas puas, tuaj yeem kuaj pom los ntawm cov hauv qab no:
Nyeem qhov ntsuas qhov ntsuas qhov txhaum cai: Yog tias muaj qhov txhaum cai hauv ABS lub khoos phis tawj, thiab lub teeb pom kev txhaum ntawm lub ntsuas hluav taws xob qhib, qhov no yuav qhia tau tias lub sensor puas lawm. cov
Field brake test: nyob rau hauv txoj kev zoo, qhov chaw dav thiab tsis muaj neeg tsav tsheb, ceev mus txog ntau tshaj 60, thiab tom qab ntawd muab tus nres mus rau qhov kawg. Yog tias lub log raug kaw thiab tsis muaj kev cuam tshuam ntawm kev sib tsoo, qhov no yuav qhia tau tias ABS tsis ua haujlwm, feem ntau yog tshwm sim los ntawm kev puas tsuaj rau ABS sensor. cov
Siv lub tshuab ntsuas ntsuas ntsuas qhov ntsuas qhov ntsuas hluav taws xob / ua haujlwm ntawm ABS sensor: tig lub log ntawm 1r / s, cov zis hluav taws xob ntawm lub log pem hauv ntej yuav tsum nyob nruab nrab ntawm 790 thiab 1140mv, lub log tsheb yuav tsum siab dua 650mv. Tsis tas li ntawd, tus nqi tsis kam ntawm ABS sensors feem ntau yog nruab nrab ntawm 1000 thiab 1300Ω. Yog tias cov kab no tsis tau ntsib, tej zaum yuav qhia tau tias muaj teeb meem nrog ABS sensor 34.
Hauv cov ntsiab lus, yog tias muaj teeb meem nrog ABS rear log sensor, yuav tsum xub xyuas seb puas muaj kev puas tsuaj rau lub cev, xws li tawg lossis pom tseeb hnav. Yog tias tsis muaj qhov pom tseeb ntawm lub cev puas tsuaj rau kev ua haujlwm tsis zoo vim hnav lossis lwm yam ua rau tuaj yeem kuaj tau ntxiv los ntawm cov txheej txheem saum toj no. cov
