Njira zowunikira sensor ya ABS

Masensa a ABS amatenga gawo lofunikira pakugwira ntchito kwa ma braking system - kuthamanga kwa mabuleki ndi magwiridwe antchito a unit yonse zimadalira iwo. Zinthu za sensor zimatumiza deta pamlingo wa kuzungulira kwa mawilo kupita ku gawo lowongolera, ndipo gawo lowongolera limasanthula zomwe zikubwera, ndikupanga algorithm yomwe mukufuna. Koma chochita ngati pali kukayikira za thanzi la zipangizo?

Zizindikiro za kulephera kwa chipangizocho

Mfundo yakuti sensor ya ABS ndi yolakwika imasonyezedwa ndi chizindikiro pa gulu la zida: imawunikira pamene dongosolo lazimitsidwa, limatuluka ngakhale ndi vuto laling'ono.

Umboni wakuti ABS wasiya "kusokoneza" mabuleki:

• Mawilo amatsekeka nthawi zonse ndi mabuleki olemetsa.
• Palibe kugogoda komwe kumamveka munthawi yomweyo kukanikiza chopondaponda.
• Singano ya Speedometer imatsalira kumbuyo kwa mathamangitsidwe kapena samasuntha konse kuchokera pomwe idayambira.
• Ngati masensa awiri (kapena kupitilira apo) pagawo la zida alephera, chizindikiro cha brake yoyimitsa magalimoto chimayaka ndipo sichimatuluka.

Chizindikiro cha ABS pa dashboard chikuwonetsa kusokonekera kwadongosolo

Ndiyenera kuchita chiyani ngati chizindikiro cha ABS pa bolodi lagalimoto sichikuyenda bwino? Simuyenera kusintha nthawi yomweyo sensa, choyamba muyenera kuyang'ana zida; njirayi ikhoza kuchitidwa paokha, popanda kugwiritsa ntchito mautumiki a ambuye olipidwa kwambiri.

Njira zowunika zaumoyo

Kuti tidziwe momwe gawolo lilili, timachita zinthu zingapo kuti tidziwe, kuyambira zosavuta mpaka zovuta:

1. Tiyeni tiyang'ane ma fusewo potsegula chipika (mkati mwa chipinda chonyamula anthu kapena m'chipinda cha injini) ndikuyang'ana zinthu zomwe zikugwirizana (zosonyezedwa mu bukhu lokonzekera / ntchito). Ngati chigawo chowotchedwa chikapezeka, tidzachisintha ndi china chatsopano.
2. Tiyeni tiwone ndikuwona:
   • kukhulupirika kwa cholumikizira;
   • kuyatsa kwa ma abrasions omwe amawonjezera chiopsezo chafupipafupi;
   • kuipitsidwa kwa mbali, zotheka kunja mawotchi kuwonongeka;
   • kukonza ndi kulumikiza pansi pa sensa yokha.

Ngati zomwe tafotokozazi sizikuthandizani kuzindikira vuto la chipangizocho, ziyenera kuyang'aniridwa ndi zida - tester (multimeter) kapena oscilloscope.

Tester (multimeter)

Kwa njira iyi yodziwira sensa, mudzafunika tester (multimeter), malangizo ogwiritsira ntchito ndi kukonza galimoto, komanso PIN - wiring ndi zolumikizira zapadera.

Chipangizochi chimagwirizanitsa ntchito za ohmmeter, ammeter ndi voltmeter

Tester (multimeter) - chipangizo choyezera magawo a magetsi, kuphatikiza ntchito za voltmeter, ammeter ndi ohmmeter. Pali mitundu ya analogi ndi digito ya zida.

Kuti mudziwe zambiri za magwiridwe antchito a sensa ya ABS, ndikofunikira kuyeza kukana kwagawo la chipangizocho:

1. Kwezani galimoto ndi jack kapena mupachike pa lift.
2. Chotsani gudumu ngati likulepheretsa kupeza chipangizocho.
3. Chotsani chivundikiro cha bokosi lowongolera ndikuchotsa zolumikizira kuchokera kwa wowongolera.
4. Timalumikiza PIN ku multimeter ndi sensor contact (zolumikizira ma gudumu lakumbuyo zili mkati mwa chipinda chokwera, pansi pa mipando).

Timalumikiza PIN ku tester ndi sensor contact

Kuwerengera kwa chipangizocho kuyenera kufanana ndi zomwe zafotokozedwa m'buku lokonzekera ndi kuyendetsa galimoto inayake. Ngati kukana kwa chipangizocho:

• pansi pamtunda wocheperako - sensa ndiyolakwika;
• kuyandikira zero - dera lalifupi;
• kusakhazikika (kudumpha) panthawi yomangitsa mawaya - kuphwanya kukhudzana mkati mwa waya;
• kuwerenga kosatha kapena kosawerengeka - kuphulika kwa chingwe.

Chenjerani! Kukana kwa masensa a ABS kutsogolo ndi kumbuyo ndi kosiyana. Magawo ogwiritsira ntchito zida amachokera ku 1 mpaka 1,3 kOhm koyamba komanso kuchokera 1,8 mpaka 2,3 kOhm yachiwiri.

Video "ABS sensor diagnostics"

Momwe mungayang'anire ndi oscilloscope (ndi chithunzi cha wiring)

Kuphatikiza pa kudzizindikira kwa sensor ndi tester (multimeter), imatha kufufuzidwa ndi chipangizo chovuta kwambiri - oscilloscope.

Chipangizochi chimayang'ana matalikidwe ndi nthawi ya chizindikiro cha sensor

Oscilloscope ndi chipangizo chomwe chimaphunzira kukula ndi nthawi ya siginecha, yomwe idapangidwa kuti izindikire molondola momwe ma pulse amayendera mumayendedwe apakompyuta. Chipangizochi chimazindikira zolumikizira zoyipa, zolakwika zapansi ndi kuphulika kwa waya. Chekecho chimachitika ndi kuyang'ana kowoneka kwa kugwedezeka pazenera la chipangizocho.

Kuti muzindikire sensa ya ABS ndi oscilloscope, muyenera:

1. Limbikitsani batire mokwanira kuti muwone kutsika kwamagetsi (ma spikes) pa zolumikizira kapena zowongolera pakuyezera.
2. Pezani sensor yogwira ndikudula cholumikizira chapamwamba pagawolo.
3. Lumikizani oscilloscope kumalo opangira magetsi.

Kulumikiza chipangizocho ku cholumikizira cha sensor cha ABS (1 - toothed disc-rotor; 2 - sensor)

Mkhalidwe wa sensor ya ABS ukuwonetsedwa ndi:

• momwemonso matalikidwe a kusinthasintha kwa chizindikiro panthawi yozungulira mawilo a chitsulo chimodzi;
• kusowa kwa matalikidwe akumenyedwa pozindikira ndi chizindikiro cha sinusoidal chafupipafupi;
• kukhalabe okhazikika ndi yunifolomu matalikidwe a oscillations chizindikiro, osapitirira 0,5 V, pamene gudumu limayenda pafupipafupi 2 rpm.

Dziwani kuti oscilloscope ndi chipangizo chovuta komanso chokwera mtengo. Ukadaulo wamakono wamakompyuta umapangitsa kuti m'malo mwa chipangizochi mukhale pulogalamu yapadera yotsitsidwa kuchokera pa intaneti ndikuyika pa laputopu wamba.

Kuwona gawo popanda zida

Njira yosavuta yodziwira chipangizo chopanda ma hardware ndikuwunika valavu ya solenoid pa sensor induction. Chitsulo chilichonse (screwdriver, wrench) chimayikidwa pagawo lomwe maginito amayikidwa. Ngati sensa siyikukopa, ndiyolakwika.

Makina ambiri amakono a anti-lock braking ali ndi ntchito yodzizindikiritsa yokha yokhala ndi zolakwika (mu zilembo za alphanumeric) pakompyuta pakompyuta. Mutha kumasulira zilembo izi pogwiritsa ntchito intaneti kapena buku la malangizo lamakina.

Zoyenera kuchita ngati kuwonongeka kwapezeka

Zoyenera kuchita ndi sensor ya ABS ngati vuto likupezeka? Ngati vuto ndilo chipangizocho chokha, chiyenera kusinthidwa, koma pa nkhani ya waya wamagetsi, mukhoza kukonza vutoli nokha. Kuti tibwezeretse kukhulupirika kwake, timagwiritsa ntchito njira ya "kuwotcherera", kukulunga mosamala zolumikizira ndi tepi yamagetsi.

Ngati kuwala kwa ABS kumabwera pa dashboard, ichi ndi chizindikiro chodziwika bwino cha vuto la sensa. Zomwe tafotokozazi zithandizira kuzindikira chomwe chimayambitsa kusokonekera; komabe, ngati chidziwitso ndi chidziwitso sizokwanira, ndi bwino kukaonana ndi ambuye agalimoto yamagalimoto. Kupanda kutero, matenda osaphunzira a mkhalidwewo, kuphatikiza ndi kukonza kolakwika kwa chipangizocho, kumachepetsa mphamvu ya anti-lock braking system ndipo kungayambitse ngozi.
