Automotive relays yog qhov tseem ceeb ntawm cov tshuab hluav taws xob hauv tsheb.Automotive teeb pom kev zoo, wipers, starters, cua txias, hluav taws xob lub rooj zaum, hluav taws xob qhov rooj thiab qhov rais, anti lock braking pab kiag li lawm, ncua kev kawm ntawv tswj, suab systems, thiab lwm yam yuav tsum tau relays.Lawv yog ib qho ntawm cov khoom siv hluav taws xob feem ntau siv hauv tsheb, ntawm cov khoom siv hluav taws xob hluav taws xob yog qhov ntxov tshaj plaws thiab feem ntau siv hom relay.Lawv yog dab tsi thiab lawv ua haujlwm li cas?Nyob rau hauv tsab xov xwm no, peb yuav nkag mus rau hauv lub ntiaj teb no ntawm automotive relays thiab tshawb nrhiav lawv cov hauv paus ntsiab lus ntawm kev ua hauj lwm thiab kev siv.

1. Lub Tsheb Relay yog dab tsi?

Automotive relays yog dav siv los tswj cov keyboards uas tswj cov tam sim no loj nrog cov tam sim no qis thaum tiv thaiv cov keyboards.Qhov tseem ceeb, nws tso cai rau kev tswj hwm lub zog loj dua nrog cov teeb liab me me.Vim muaj qhov xav tau tam sim no ntau, cov keyboards xws li horns, starters, headlights, thiab lwm yam tuaj yeem ua rau hluav taws xob poob siab thiab yaig.Yog tias muaj ib qho relay, tsuas yog me me ntawm tam sim no dhau los ntawm kev tswj kev hloov pauv tsis tshua muaj peev xwm ua rau tawg ntawm qhov hloov.Yog li, peb feem ntau hais tias relays yog tus choj ntawm cov hluav taws xob qis hluav taws xob thiab cov hluav taws xob hluav taws xob siab.

2.Vim li cas Lub Tsheb Xav Tau Relays?

Automotive relays yog qhov tseem ceeb vim tias lawv tso cai rau kev siv me me thiab qis dua qhov muaj peev xwm hloov thiab cov xov hlau hauv kev tswj xyuas tsheb.Qhov no tuaj yeem txo qhov load ntawm lub tsheb thaiv cov hlua khi thiab cov keyboards, thiab tiv thaiv kom tsis txhob muaj cua sov thiab hluav taws xob puas.Tsis tas li ntawd, txoj hauj lwm ntawm lub relay tuaj yeem nyob ze rau ntawm cov khoom uas nws tswj, yog li txo qis voltage poob ntawm cov xov hlau.

3. Cov qauv ntawm lub tsheb Relay

Automotive relays feem ntau yog tsim los ntawmHlau Core, Coil, YOKE, Armature, Caij nplooj ntoos hlav, Hu rau, thiab lwm yam kev sib cuag tau muab faib uaTsiv ContactthiabFixed Contact (Stationary Contact).Raws li hom kev sib cuag, relays feem ntau muab faib ua ob hom:

1. Ua & tawg Relay

Nws tseem hu uaSPST(Ib leeg-Pole, Ib-Tsho).Muaj 4 tus pins (los yog terminals) ntawm lub cev nrog ib qho hluav taws xob tam sim no thiab kev sib cuag.Qhov kev sib cuag yog qhib los yog kaw nyob ntawm seb lub relay nyob rau hauv so los yog energized.

● NC:Yog hais tias qhov kev sib cuag raug kaw thaum lub relay nyob twj ywm, lub relay hu ua Nquag Kaw.

●NO: Yog hais tias qhov kev sib cuag qhib thaum lub relay nyob twj ywm, lub relay hu uaNquag Qhib. Cov relays no yog hom ntau dua.

2. Hloov Relay

Nws tseem hu uaSPDT(Ib leeg-ncej, muab ob npaug rau).Muaj5 pin(los yog terminals) ntawm lub cev, muaj ob qhov kev sib cuag txuas nrog lub davhlau ya nyob twg.Lub relays muaj ob lub voj voog, ib qho yog kaw thaum lub relay yog so, thiab lwm qhov yog kaw thaum lub relay yog energized.

Relay-Kev tsim kho ntawm Automotive Relays

4. Lub Tsheb Relay ua haujlwm li cas?

Cov duab hauv qab no qhia txog cov txheej txheem ua haujlwm ntawm relay.Txhawm rau kom nkag siab yooj yim, qhov txaus nyiam electromagnetic relay yog muab ntawm no.Nyob rau hauv txhua yam ntawm automotive relay, lub ntsiab Cheebtsam yog lub kauj, armature, thiab kev sib cuag.Ib tug hlau yog mob nyob ib ncig ntawm lub magnetic core, tsim ib tug electromagnet.Thaum muab lub zog rau lub kauj, nws yuav ua kom muaj zog thiab ua kom muaj hluav taws xob.Lub armature yog ib qho khoom siv txav tau uas nws lub luag haujlwm tseem ceeb yog qhib lossis kaw kev sib cuag.Nws txuas nrog lub caij nplooj ntoos hlav, yog li nyob rau hauv kev ua haujlwm ib txwm muaj, lub armature rov qab mus rau nws txoj haujlwm qub.

1. Power-Up State

Yog tias lub zog hluav taws xob muaj zog rau lub kauj, lub relay lub electromagnetic kauj yog energized thiab generates ib tug sib nqus flux proportional rau tam sim no ntws los ntawm nws.Qhov no magnetic teb attracts lub armature mus rau lub electromagnet, yog li ntawd cov tsiv thiab nyob ruaj ruaj nyob ze rau ib leeg, raws li qhia nyob rau hauv daim duab hauv qab no.Thaum lub relay yog energized, tsis muaj terminal contacts thaum lub NC contact tseem ntab.

2.Power-Off State

Thaum tsis muaj fais fab mov rau lub relay electromagnetic coil, tsis muaj magnetic flux generated, yog li lub armature nyob rau hauv ib qho chaw ruaj khov.Yog li ntawd, ob qho tib si kev sib cuag tseem tsis hloov pauv thiab muaj qhov sib txawv me me ntawm cov kev sib cuag no.Hauv lwm lo lus, NC kev sib tiv tauj tuaj rau hauv kev sib cuag thaum lub kauj yog kaw.

5. Kev Siv Tsheb Relays

Automotive relays muaj ntau yam siv, suav nrog:

Pib:Pib lub cev muaj zog yuav tsum muaj ntau qhov tam sim no los pib lub cav.Lub relay tso cai rau lub ignition hloov los tswj lub siab tam sim no load.

Lub teeb taub hau:Relays feem ntau yog siv los tswj lub teeb taub hau, kom ntseeg tau tias lawv tau txais lub zog txaus thiab tiv thaiv kev poob qis uas tuaj yeem ua rau lub teeb ci.

Roj twj tso kua mis:Lub twj tso kua mis roj yuav tsum muaj ntau qhov tam sim no kom xa cov roj mus rau lub cav.Lub relay xyuas kom meej tias nws tau txais lub zog tsim nyog.

Horn:Lub tsheb horns xav tau ntau npaum li cas tam sim no.Lub relay tso cai rau lub horn khawm tswj lub horn.

Nws tuaj yeem hais tias automotive relays yog unsung heroes hauv kev lag luam tsheb.Lawv muab txoj hauv kev ua tau zoo thiab muaj txiaj ntsig los tswj cov tam sim no hauv lub tsheb, tso cai rau koj kom muaj zog cov khoom siv hluav taws xob tam sim no yam tsis muaj hluav taws xob ntau dhau.Typhoenix muaj ntau yamtsheb relaystiv thaiv koj lub tsheb.
