ABS sensor resistance Lexus px 300

Nzira dzekutarisa iyo ABS sensor

ABS sensors inoita basa rakakosha mukushanda kweiyo mota yebraking system - iyo braking kunyatsoshanda uye kushanda zvakanaka kweyuniti yese kunoenderana navo. Sensor zvinhu zvinoendesa data pachiyero chekutenderera kwemavhiri kune yekudzora unit, uye iyo control unit inoongorora iyo inouya ruzivo, ichivaka inodiwa algorithm yezviito. Asi chii chaunofanira kuita kana pane kusava nechokwadi pamusoro pehutano hwezvigadzirwa?

Zviratidzo zvekutadza kushanda kwemudziyo

Icho chokwadi chekuti sensor yeABS yakanganisa inoratidzwa nechiratidzo pane mudziyo wemidziyo: inovhenekera kana sisitimu yadzimwa, inobuda kunze kunyangwe nekusashanda kudiki.

Uchapupu hwekuti ABS yakamira "kupindira" nemabhureki:

• Mavhiri anogara akavharika pasi peheavy braking.
• Iko hakuna hunhu hwekugogodza nekuzunguza panguva imwe chete kana uchidzvanya brake pedal.
• Iyo speedometer tsono inosara kumashure kwekumhanyisa kana kuti haifambi zvachose kubva panzvimbo yayo yepakutanga.
• Kana maviri (kana anopfuura) ma sensors pane chiridzwa chepanhi akatadza, iyo yekupaka brake chiratidzo inovhenekera uye haibude.

Iyo ABS chiratidzo pane dashboard inoratidza kusashanda kwehurongwa

Chii chandinofanira kuita kana chiratidzo cheABS chiri padeshibhodhi yemotokari chisingaiti nemazvo? Iwe haufanirwe kuchinja nekukurumidza sensor, iwe unofanirwa kutanga watarisa zvishandiso; nzira iyi inogona kuitwa yakazvimirira, pasina kushandisa masevhisi evanobhadhara zvakanyanya masters.

Nzira dzekutarisa kushanda

Kuti tione mamiriro echikamu, tinoita zvakatevedzana zviito kuti tizviongorore, kubva pane nyore kuenda kune yakaoma:

1. Ngatitarisei mafuse nekuvhura bhuroka (mukati mekamuri yevatyairi kana mukamuri yeinjini) uye nekuongorora zvinhu zvinoenderana (zvinoratidzwa mubhuku rekugadzirisa / rekushandisa). Kana chikamu chakatsva chikawanikwa, tichachitsiva nechitsva.
2. Ngatitarisei uye titarise:
   • connector kuperera;
   • wiring yeabrasions inowedzera njodzi yepfupi pfupi;
   • kusvibiswa kwezvikamu, zvichibvira kunze kwemagetsi kukanganisa;
   • kugadzirisa uye kubatanidza pasi pe sensor pachayo.

Kana matanho ari pamusoro apa asingabatsire kuona kusashanda kwemudziyo, inofanira kuongororwa nemidziyo - tester (multimeter) kana oscilloscope.

Tester (multimeter)

Kune iyi nzira yekuongorora sensor, iwe uchada tester (multimeter), mirayiridzo yekushanda nekugadzirisa motokari, pamwe nePIN - wiring ine zvibatanidza zvakakosha.

Chishandiso chinosanganisa mabasa eiyo ohmmeter, ammeter uye voltmeter

Tester (multimeter) - chigadziro chekuyera zviyero zvemagetsi emagetsi, kubatanidza mabasa e voltmeter, ammeter uye ohmmeter. Kune analog uye digital modhi yemidziyo.

Kuti uwane ruzivo rwakakwana nezve mashandiro eiyo ABS sensor, zvinodikanwa kuyera kupokana mudunhu remudziyo:

1. Simudza motokari nejeko kana kuti iturike parift.
2. Bvisa vhiri kana richitadzisa kuwana mudziyo.
3. Bvisa system control bhokisi chivharo uye bvisa zvibatanidza kubva kune controller.
4. Isu tinobatanidza iyo PIN kune multimeter uye iyo sensor yekubata (yekumashure vhiri sensor majoini anowanikwa mukati mekamuri yevafambi, pasi pezvigaro).

Isu tinobatanidza iyo PIN kune tester uye sensor yekubata

Kuverengerwa kwechigadzirwa kunofanirwa kuenderana neiyo data inotsanangurwa mubhuku rekugadzirisa uye kushanda kweimwe mota. Kana kupesana kwechigadzirwa:

• pazasi pechikumbaridzo chidiki - sensor yakashata;
• inosvika zero - pfupi pfupi;
• kusagadzikana (kusvetuka) panguva yekusimbisa waya - kukanganisa kwekubatana mukati me wiring;
• kusingaperi kana kusaverengeka - cable break.

Attention! Kupokana kweABS sensors kumberi uye kumashure maaxles kwakasiyana. Maitiro ekushandisa emidziyo anobva 1 kusvika 1,3 kOhm mune yekutanga kesi uye kubva 1,8 kusvika 2,3 kOhm mune yechipiri.

Vhidhiyo "ABS sensor diagnostics"

Maitiro ekutarisa ne oscilloscope (ine wiring diagraph)

Mukuwedzera kune kuzviongorora kwe sensor ine tester (multimeter), inogona kuongororwa nemudziyo wakaoma - oscilloscope.

Chishandiso chinoongorora amplitude uye nguva paramita yechiratidzo che sensor

An oscilloscope chishandiso chinodzidza amplitude uye nguva paramita yechiratidzo, iyo yakagadzirirwa kunyatsoongorora pulse maitiro mumaseketi emagetsi. Mudziyo uyu unoona kubatanidza kwakashata, zvikanganiso zvepasi uye kuputsika kwewaya. Cheki inoitwa nekutarisa kwekuona kwekudengenyeka pahwindo remudziyo.

Kuti uongorore iyo ABS sensor ine oscilloscope, unofanirwa:

1. Chaja bhatiri zvakazara kuitira kuti utarise kudonha kwevoltage (spikes) pazvibatanidza kana zvinotungamira panguva yekuyera.
2. Tsvaga iyo yekubata sensor uye bvisa iyo yepamusoro yekubatanidza kubva pachikamu.
3. Batanidza oscilloscope kune chinobuda magetsi.

Kubatanidza chishandiso kune ABS sensor yekubatanidza (1 - toothed disc-rotor; 2 - sensor)

Mamiriro eiyo ABS sensor inoratidzwa ne:

• iwo amplitude imwechete yekuchinja kwechiratidzo panguva yekutenderera kwemavhiri eekisesi imwe;
• kusavapo kweamplitude beats paunenge uchiongorora nechiratidzo che sinusoidal chenguva yakaderera;
• kuchengetedza yakagadzikana uye yunifomu amplitude yechiratidzo oscillations, isingapfuuri 0,5 V, apo gumbo rinotenderera pane frequency ye2 rpm.

Ziva kuti oscilloscope chinhu chakaoma uye chinodhura mudziyo. Tekinoroji yemazuva ano yemakombuta inoita kuti zvikwanise kutsiva chishandiso ichi nechirongwa chakakosha chakatorwa kubva paInternet uye chakaiswa palaptop yenguva dzose.

Kuongorora chikamu chisina zviridzwa

Iyo iri nyore nzira yekuongorora iyo hardware-isina mudziyo ndeyekutarisa solenoid valve pane induction sensor. Chero chigadzirwa chesimbi (screwdriver, wrench) chinoshandiswa kune chikamu icho magineti akaiswa. Kana iyo sensor isingaikwevedze, inokanganisa.

Mazhinji emazuvano emotokari anodzivirira kukiya mabhureki masisitimu ane yekuzviongorora basa nekukanganisa kubuda (mu alphanumeric coding) pane-bhodhi komputa skrini. Unogona kududzira zviratidzo izvi uchishandisa Indaneti kana bhuku rekuraira remuchina.

Zvekuita kana kuputsika kukaonekwa

Chii chekuita neABS sensor kana kusashanda kwakaonekwa? Kana dambudziko riri mudziyo wacho pachawo, huchafanira kuchinjwa, asi munyaya ye wiring yemagetsi, unogona kugadzirisa dambudziko racho iwe pachako. Kuti tidzorere kuvimbika kwayo, tinoshandisa nzira ye "welding", tichinyatsoputira majoini ne tepi yemagetsi.

Kana iyo ABS mwenje ichiuya pa dashboard, ichi chiratidzo chakajeka chedambudziko re sensor. Izvo zviito zvinotsanangurwa zvichabatsira kuziva chikonzero chekuparara; zvisinei, kana ruzivo uye ruzivo hazvina kukwana, zviri nani kuonana nevatenzi vebasa remotokari. Zvikasadaro, kuongororwa kusingaverengeki kwemamiriro ezvinhu, pamwe nekugadziriswa kusina kunaka kwechigadzirwa, kunoderedza kushanda kweiyo anti-lock braking system uye zvinogona kutungamirira kutsaona.
