Department: Nres Systems - Kawm cov secrets ntawm sensors

Patronage: ATE Continental. Lub log sensor system nyob rau hauv niaj hnub braking systems, xws li SBD ASR, EDS thiab ESP, yog tsim los xa cov ntaub ntawv hais txog tus naj npawb ntawm lub log revolutions mus rau tus tswj tsim nyog.

Muab tso rau hauv Brake systems

Board of Trustees: ATE Continental

Qhov tseeb dua cov ntaub ntawv hais txog qhov system no, qhov kev hloov kho kom zoo dua thiab yooj yim dua, uas txhais tau hais tias qhov zoo tshaj plaws thiab ruaj khov dua lub braking system.

Passive (inductive) sensor

Nyob rau hauv thaum ntxov xyoo ntawm ABS systems, nws yog txaus rau lub log sensors muab lub teeb liab los ntawm lub sij hawm ib tug ceev ntawm kwv yees li 7 km / h. Tom qab ABS tau nthuav dav nrog cov haujlwm ntxiv, xws li: ASR, EDS thiab ESP. , nws tau los ua qhov tsim nyog uas tus qauv tsim tuaj yeem xa cov teeb liab tag nrho. Passive sensors tau txhim kho kom muaj peev xwm kuaj xyuas qhov nrawm li 3 km / h, tab sis qhov no yog qhov txwv ntawm lawv lub peev xwm.

Active sensor (magnetic tsis kam)

Tshiab tiam active sensors ntes ceev ntawm 0 km / h thawj zaug. Yog tias peb sib piv ob lub tshuab sensor, peb tuaj yeem pom tias cov sensors passive tau dhau los ua qhov teeb meem sinusoidal. Cov teeb liab no tau ua tiav los ntawm ABS cov tswj hwm mus rau hauv ib lub xwmfab nthwv dej vim tias tsuas yog cov teeb liab no tso cai rau cov tswj hwm ua qhov tsim nyog suav. Nws yog qhov tseeb ntawm txoj haujlwm no ntawm ABS cov tswj hwm - hloov lub teeb liab sinusoidal rau hauv plaub fab - uas yog pauv mus rau lub log active sensor. Qhov no txhais tau tias: lub active sensor tsim ib tug plaub-txoj kev teeb liab, uas yog ncaj qha siv los ntawm ABS tswj chav tsev rau cov tsim nyog xam. Tus nqi ntawm lub teeb liab sensor rau lub suab, lub log ceev thiab lub tsheb ceev tseem tsis hloov.

Tsim thiab ua haujlwm ntawm passive sensor.

Ib qho inductive sensor muaj cov hlau nplaum uas nyob ib puag ncig ntawm lub kauj. Ob qhov kawg ntawm lub kauj yog txuas nrog ABS tswj. ABS lub nplhaib iav yog nyob ntawm lub hub lossis driveshaft. Raws li lub log tig, cov kab hlau nplaum ntawm lub log sensor cuam tshuam los ntawm ABS toothed nplhaib, ua rau muaj qhov hluav taws xob sinusoidal tsim (induced) hauv lub log sensor. Los ntawm kev hloov pauv tas mus li: txhuam hniav, txhuam hniav, qhov zaus yog tsim, uas tau xa mus rau ABS maub los. Qhov no zaus nyob ntawm lub log ceev.

Cov qauv thiab kev ua haujlwm ntawm lub active sensor

Lub magnetoresistive sensor muaj plaub qhov hloov pauv tau.

magnetically, voltage qhov chaw thiab sib piv (hluav taws xob amplifier). Lub hauv paus ntsiab lus ntawm kev ntsuas los ntawm plaub tus resistors paub hauv physics li tus choj Wheatstone. Rau qhov system sensor kom ua haujlwm zoo, yuav tsum muaj lub log decoding. Lub nplhaib toothed ntawm lub sensor overlaps ob lub resistors thaum lub sij hawm txav, yog li kuaj xyuas tus choj ntsuas thiab tsim cov teeb liab sinusoidal. Nyeem ntawv hluav taws xob - tus sib piv hloov lub teeb liab sinusoidal rau hauv ib lub duab plaub. Cov teeb liab no tuaj yeem siv ncaj qha los ntawm ABS maub los rau kev suav txuas ntxiv.Lub tshuab hluav taws xob nquag hauv cov tsheb nrog lub log decoding muaj lub sensor thiab cov hlau nplaum me me. Lub log decoding muaj alternating polarity: sab qaum teb thiab sab qab teb ncej alternating. Cov txheej txheem magnetized yog them nrog roj hmab txheej. Lub log decoding kuj tuaj yeem tsim ncaj qha rau hauv lub hub.

Txhim khu kev kuaj mob

Thaum daws teeb meem niaj hnub tswj lub tshuab nres tsheb, cov kws tshaj lij tam sim no xav tau, ntxiv rau kev kuaj xyuas cov tswj hwm, cov cuab yeej tsim nyog rau kev ntseeg siab rau cov tshuab ntsuas ntsuas. Txoj haujlwm no yog ua los ntawm tus tshiab ATE AST tester los ntawm Continental Teves. Nws tso cai rau koj kom sai thiab nyab xeeb sim passive thiab nquag log ceev sensors. Nyob rau hauv active sensor systems, nws muaj peev xwm tswj tau lub impulse log yam tsis tau tshem lawv. Siv cov kab txuas txuas ntxiv, ATE AST sensor tseem tuaj yeem kuaj lwm yam ATE ESP sensors xws li lub tsheb tig sensor, lub siab sensor, thiab longitudinal thiab lateral acceleration sensors. Yog tias cov khoom siv hluav taws xob, cov teeb liab tso tawm thiab tus pin txoj haujlwm ntawm lub ntsaws yog paub, nws tseem tuaj yeem txheeb xyuas cov sensors ntawm lwm lub tsheb. Ua tsaug rau ATE AST tester, lub sijhawm siv sijhawm thiab kev kuaj xyuas tus nqi ntawm cov sensors thiab lwm yam khoom los ntawm lawv qhov kev sim hloov pauv yog

yav dhau los

Kev ua haujlwm zoo tshaj plaws

ATE AST Sensor Tester muaj qhov loj, yooj yim-rau-nyeem zaub nrog kev xaiv qhib lub teeb rov qab. Lub sensor yog tswj los ntawm plaub daim ntawv nyees khawm sau nyob rau hauv txoj kev intuitive. Nws yog ib qho khoom siv ua ke

fais fab mov los ntawm lub tsheb lub onboard network Ua hauj lwm nrog ATE AST tester yog intuitive kiag li. Cov ntawv qhia zaub mov yog tsim nyob rau hauv xws li ib txoj kev uas tus neeg siv mus los ntawm tag nrho cov txheej txheem kuaj mob ib kauj ruam. Yog li koj tsis tas yuav kawm phau ntawv qhia ntev.

Tsis siv neeg sensor paub

Thaum kuaj kev sib hloov ceev sensors, lub tshuab hluav taws xob ntse, tom qab txuas thiab tig ntawm lub ntsuas ntsuas, cia li lees paub seb lub ntsuas hluav taws xob puas ua haujlwm lossis ua haujlwm, thawj lossis thib ob tiam. Cov txheej txheem kuaj ntxiv yog nyob ntawm hom sensor pom. Yog tias qhov ntsuas qhov ntsuas tau sib txawv ntawm qhov tseeb, tus neeg siv tau muab cov lus qhia kom pom qhov yuam kev.

Kev nqis peev yav tom ntej

Ua tsaug rau lub cim xeeb flash, software ntawm ATE AST sensor tester tuaj yeem hloov kho txhua lub sijhawm ntawm PC interface. Qhov no ua rau nws yooj yim los hloov cov nqi txwv. Qhov kev ntsuas qhov ua tau zoo no yog qhov kev nqis peev uas tuaj yeem tshawb xyuas qhov yuam kev hauv lub log nrawm thiab ESP system.

Cov kev cai yooj yim rau kev ua haujlwm nrog ABS sib nqus log bearings:

• Tsis txhob muab lub log bearing rau ntawm qhov chaw ua haujlwm qias neeg,

• Tsis txhob muab lub log bearing nrog lub nplhaib sib nqus ze ntawm cov hlau nplaum ruaj khov.

Nco ntsoov tshem tawm lub active log sensor:

• Tsis txhob ntxig cov khoom ntse rau hauv lub qhov uas lub ABS sensor tau teeb tsa, vim qhov no yuav ua rau lub nplhaib sib nqus puas.

Log bearing installation daim ntawv:

• Nco ntsoov tias sab nrog lub nplhaib sib nqus ntsib lub log sensor,

• mount bearings tsuas yog ua raws li cov lus pom zoo ntawm lawv cov chaw tsim khoom lossis cov chaw tsim khoom tsheb,

• Tsis txhob tsav tsheb nrog rauj,

• tsuas yog nias hauv bearings siv cov cuab yeej tsim nyog,

• Tsis txhob ua rau lub nplhaib sib nqus ua kom puas.
