Nā ala e nānā ai i ka mea ʻike ABS

ʻO ka pale ʻana o ka mea ʻike ABS Lexus px 300

He kuleana koʻikoʻi nā mea ʻike ABS i ka hana ʻana o ka ʻōnaehana braking o ke kaʻa - ʻo ka maikaʻi o ka braking a me ka maʻalahi o ka hana holoʻokoʻa ma luna o lākou. Hoʻouna nā mea sensor i ka ʻikepili e pili ana i ke kiʻekiʻe o ka rotation o nā huila i ka ʻāpana hoʻomalu, a ʻo ka ʻāpana hoʻomalu e kālailai i ka ʻike e hiki mai ana, e kūkulu ana i ka algorithm makemake o nā hana. Akā he aha ka mea e hana ai inā he kānalua e pili ana i ke olakino o nā mea hana?

Nā hōʻailona o ka hana ʻino ʻana o ka mea hana

ʻO ka hewa o ka sensor ABS ua hōʻailona ʻia e kahi hōʻailona ma ka panel mea kani: e hoʻomālamalama ana i ka wā e pio ai ka ʻōnaehana, hele i waho me ka liʻiliʻi liʻiliʻi.

ʻO nā hōʻike i hoʻopau ʻia ka ABS i ka "keakea" i nā kaʻa:

  • Paʻa mau nā huila ma lalo o ka haʻalulu nui.
  • ʻAʻohe ʻano kīkēkē me ka haʻalulu like ʻana i ke kaomi ʻana i ka pedal brake.
  • ʻAʻole neʻe iki ka nila speedometer mai kona kūlana kumu.
  • Inā hāʻule ʻelua (a ʻoi aʻe paha) nā mea ʻike ma ka pā mea mea kani, ʻaʻa ka hōʻailona kaʻa kaʻa a ʻaʻole pio.

ʻO ka pale ʻana o ka mea ʻike ABS Lexus px 300

ʻO ka hōʻailona ABS ma ka dashboard e hōʻike ana i kahi hana hewa o ka ʻōnaehana

He aha kaʻu e hana ai inā ʻaʻole pololei ka ʻōkuhi ABS ma ka dashboard o ke kaʻa? ʻAʻole pono ʻoe e hoʻololi koke i ka sensor, pono ʻoe e nānā mua i nā mea hana; hiki ke hana kaʻawale i kēia kaʻina hana, me ka ʻole e hoʻohana i nā lawelawe a nā haku uku nui.

Nā hana hōʻoia olakino

No ka hoʻoholo ʻana i ke kūlana o ka ʻāpana, hana mākou i nā ʻano hana e ʻike ai iā ia, mai ka maʻalahi a paʻakikī:

  1. E nānā kākou i nā fuses ma ka wehe ʻana i ka poloka (i loko o ke keʻena kaʻahele a i ʻole ke keʻena mīkini) a nānā i nā mea e pili ana (i hōʻike ʻia ma ka manual repair / operation manual). Inā ʻike ʻia kahi mea puhi, e hoʻololi mākou iā ia me kahi mea hou.
  2. E nānā a nānā:
    • hoʻohui pono;
    • uwea no ka abrasions e hoonui i ka pilikia o ke kaapuni pokole;
    • ka hoʻohaumia ʻana o nā ʻāpana, hiki ke hōʻino ʻia i waho;
    • ka hoʻopaʻa ʻana a me ka hoʻopili ʻana i ka lepo o ka sensor ponoʻī.

Inā ʻaʻole kōkua nā ana i luna e ʻike i kahi hana hewa ʻole, pono e nānā ʻia me nā mea hana - kahi hōʻike (multimeter) a i ʻole kahi oscilloscope.

Mea ho'āʻo (multimeter)

No kēia ʻano o ka ʻike ʻana i ka sensor, pono ʻoe i kahi mea hōʻike (multimeter), nā ʻōlelo aʻoaʻo no ka hana ʻana a me ka hoʻoponopono ʻana i ke kaʻa, a me ka PIN - wiring me nā mea hoʻohui kūikawā.

ʻO ka pale ʻana o ka mea ʻike ABS Lexus px 300

Hoʻohui ka mea hana i nā hana o kahi ohmmeter, ammeter a me voltmeter

Tester (multimeter) - he mea hana no ke ana ʻana i nā ʻāpana o ke au uila, e hui pū ana i nā hana o kahi voltmeter, ammeter a me ohmmeter. Aia nā ʻano analog a me nā kikohoʻe o nā mea hana.

No ka loaʻa ʻana o ka ʻike piha e pili ana i ka hana ʻana o ka sensor ABS, pono ia e ana i ke kū'ē ʻana i ke kaapuni hāmeʻa:

  1. E hoʻokiʻekiʻe i ke kaʻa me kahi jack a i ʻole e kau ʻia ma luna o kahi hāpai.
  2. Wehe i ka huila inā keakea ia i ke komo ʻana i ka hāmeʻa.
  3. Wehe i ka uhi pahu hoʻomalu ʻōnaehana a wehe i nā mea hoʻohui mai ka mea hoʻoponopono.
  4. Hoʻohui mākou i ka PIN i ka multimeter a me ka mea hoʻopili sensor (aia nā mea hoʻohui sensor huila hope i loko o ke keʻena kaʻa, ma lalo o nā noho).

ʻO ka pale ʻana o ka mea ʻike ABS Lexus px 300

Hoʻopili mākou i ka PIN i ka mea hoʻāʻo a me ka pilina sensor

Pono nā heluhelu o ka hāmeʻa e like me ka ʻikepili i kuhikuhi ʻia ma ka manual no ka hoʻoponopono a me ka hana ʻana o kahi kaʻa. Inā ʻo ke kūpaʻa o ka mea hana:

  • ma lalo o ka paepae liʻiliʻi - hewa ka ʻike;
  • hoʻokokoke ʻole - pōkole pōkole;
  • paʻa ʻole (lele) i ka manawa o ka hoʻopaʻa ʻana i nā uea - he uhaki i ka pilina i loko o ka uwila;
  • pau ʻole a ʻaʻohe heluhelu - hoʻomaha kelepona.

Nānā! ʻOkoʻa ke kūʻē o nā mea ʻike ABS ma ke alo a me hope. ʻO nā palena hana o nā mea hana mai 1 a 1,3 kOhm i ka hihia mua a mai 1,8 a 2,3 kOhm i ka lua.

Wikiō "ABS sensor diagnostics"

Pehea e nānā ai me kahi oscilloscope (me ke kiʻikuhi wili)

Ma waho aʻe o ka ʻike pilikino o ka sensor me kahi mea hōʻike (multimeter), hiki ke nānā ʻia me kahi mea paʻakikī - kahi oscilloscope.

ʻO ka pale ʻana o ka mea ʻike ABS Lexus px 300

Nānā ka mea hana i ka amplitude a me nā palena manawa o ka hōʻailona sensor

ʻO ka oscilloscope kahi mea e aʻo ai i ka amplitude a me nā palena manawa o kahi hōʻailona, ​​​​i hoʻolālā ʻia e ʻike pono i nā kaʻina pulse i nā kaʻa uila. Ke ʻike nei kēia mea i nā mea hoʻohui maikaʻi ʻole, nā hemahema o ka honua a me nā naki uwea. Hoʻokō ʻia ka nānā ʻana ma ka nānā ʻana i nā haʻalulu ma ka pale o ka hāmeʻa.

No ka ʻike ʻana i ka sensor ABS me kahi oscilloscope, pono ʻoe:

  1. E hoʻopiha piha i ka pākaukau no ka nānā ʻana i ka hāʻule o ka volta (spike) ma nā mea hoʻohui a i ʻole ke alakaʻi i ka wā o ke ana.
  2. E huli i ka mea ʻike paʻi a hoʻokaʻawale i ka mea hoʻohui luna mai ka ʻāpana.
  3. Hoʻohui i ka oscilloscope i kahi puka mana.

ʻO ka pale ʻana o ka mea ʻike ABS Lexus px 300

Hoʻohui ʻana i ka hāmeʻa i ka mea hoʻopili sensor ABS (1 - toothed disc-rotor; 2 - sensor)

Hōʻike ʻia ke kūlana o ka sensor ABS e:

  • ka amplitude like o ka hoʻololi ʻana o ka hōʻailona i ka wā o ka hoʻololi ʻana o nā huila o hoʻokahi axle;
  • ka nele o ka amplitude beats i ka wā e ʻike ai me kahi hōʻailona sinusoidal o kahi alapine haʻahaʻa;
  • ka mālama ʻana i kahi amplitude kūpaʻa a kūlike o nā oscillations hōʻailona, ​​ʻaʻole i ʻoi aku ma mua o 0,5 V, i ka wā e hoʻohuli ai ka huila i ke alapine o 2 rpm.

E hoʻomaopopo he mea paʻakikī a pipiʻi ka oscilloscope. Hiki i ka ʻenehana kamepiula hou ke hoʻololi i kēia hāmeʻa me kahi polokalamu kūikawā i hoʻoiho ʻia mai ka Pūnaewele a hoʻokomo ʻia ma kahi kamepiula maʻamau.

Ke nānā ʻana i kahi ʻāpana me ka ʻole o nā mea hana

ʻO ke ala maʻalahi loa e ʻike ai i kahi hāmeʻa ʻole ka nānā ʻana i ka valve solenoid ma ka sensor induction. Hoʻopili ʻia kēlā me kēia huahana metala (screwdriver, wrench) i ka ʻāpana i hoʻokomo ʻia ai ka magnet. Inā ʻaʻole huki ka mea ʻike iā ia, he hemahema.

ʻO ka hapa nui o nā ʻōnaehana anti-lock braking hou i loaʻa i kahi hana hoʻomaʻamaʻa ponoʻī me ka puka hewa (ma ka alphanumeric coding) ma ka ʻaoʻao kamepiula ma luna o ka papa. Hiki iā ʻoe ke wehewehe i kēia mau hōʻailona me ka hoʻohana ʻana i ka Pūnaewele a i ʻole ka manual aʻoaʻo o ka mīkini.

He aha ka hana inā ʻike ʻia kahi haki

He aha ka mea e hana ai me ka sensor ABS inā ʻike ʻia kahi hana hewa? Inā ʻo ka pilikia ka mea ponoʻī, pono e hoʻololi ʻia, akā i ke ʻano o ka uila uila, hiki iā ʻoe ke hoʻoponopono iā ʻoe iho. No ka hoʻihoʻi hou ʻana i kona kūpaʻa, hoʻohana mākou i ke ʻano "weld", e kāʻei pono i nā hono me ka lipine uila.

Inā hele mai ke kukui ABS ma ka dashboard, he hōʻailona maopopo kēia o ka pilikia sensor. E kōkua nā hana i wehewehe ʻia e ʻike i ke kumu o ka haki ʻana; akā naʻe, inā ʻaʻole lawa ka ʻike a me ka ʻike, ʻoi aku ka maikaʻi o ka hoʻopili ʻana i nā haku lawelawe kaʻa. A i ʻole, ʻo nā diagnostics ʻike ʻole o ke kūlana, i hui pū ʻia me ka hoʻoponopono kūpono ʻole o ka hāmeʻa, e hōʻemi i ka pono o ka ʻōnaehana anti-lock braking a hiki ke alakaʻi i kahi pōʻino.
