Dipatimenti: Brake Systems - Phunzirani zinsinsi za masensa

Othandizira: ATE Continental. Dongosolo la sensa yama gudumu mumayendedwe amakono a braking, monga SBD ASR, EDS ndi ESP, adapangidwa kuti atumize zambiri za kuchuluka kwa magudumu kwa wowongolera woyenera.

Yolembedwa mu Brake systems

Bungwe la Matrasti: ATE Continental

Zolondola kwambiri zomwe dongosololi likunena, kusinthako kumakhala bwino komanso komasuka, zomwe zikutanthauza kuti makina oyendetsa mabuleki amakhala angwiro komanso olimba.

Sensor yodutsa (inductive).

M'zaka zoyambirira za machitidwe a ABS, zinali zokwanira kuti masensa a magudumu apereke chizindikiro kuchokera pamene liwiro linafika pafupifupi 7 km / h. , zinakhala zofunikira kuti mapangidwewo apereke chizindikiro chonse. Masensa a Passive adasinthidwa kuti athe kuzindikira kuthamanga kwa 3 km / h, koma ichi chinali malire a kuthekera kwawo.

Sensor yogwira ntchito (magnetic resistance)

Masensa atsopano omwe amagwira ntchito amazindikira kuthamanga kuchokera ku 0 km / h kwa nthawi yoyamba. Tikayerekeza machitidwe onse a sensor, titha kuwona kuti masensa osagwira ntchito mpaka pano apanga chizindikiro cha sinusoidal. Chizindikirochi chinakonzedwa ndi olamulira a ABS kukhala mafunde apakati, chifukwa zizindikiro zoterezi zimalola olamulira kuchita mawerengedwe oyenera. Ndi ntchito iyi ya olamulira ABS - kutembenuza sinusoidal chizindikiro mu quadrilateral - kuti anasamutsidwa yogwira gudumu sensa. Izi zikutanthauza: sensa yogwira imapanga chizindikiro cha njira zinayi, zomwe zimagwiritsidwa ntchito mwachindunji ndi ABS control unit kuti ziwerengetse zofunikira. Mtengo wa chizindikiro cha sensa ya phula, liwiro la gudumu ndi liwiro lagalimoto sizisintha.

Kupanga ndi ntchito ya passive sensor.

Sensa yochititsa chidwi imakhala ndi maginito a maginito ozunguliridwa ndi koyilo. Mapeto onse a koyilo amalumikizidwa Woyang'anira ABS. Giya mphete ya ABS ili pamtunda kapena pa driveshaft. Pamene gudumu limazungulira, mizere ya maginito ya sensa yamagudumu imadutsa mu mphete ya ABS, zomwe zimapangitsa kuti magetsi a sinusoidal apangidwe (kupangitsa) mu sensa yamagudumu. Kupyolera mu kusintha kosalekeza: kuthyola dzino, kuthyola mano, mafupipafupi amapangidwa, omwe amaperekedwa kwa wolamulira wa ABS. Nthawi zambiri izi zimatengera liwiro la gudumu.

Kupanga ndi ntchito ya sensa yogwira ntchito

Sensa ya magnetoresistive imakhala ndi zopinga zinayi zosinthika.

magnetically, gwero lamagetsi ndi comparator (magetsi amplifier). Mfundo yoyezera kudzera pa zopinga zinayi imadziwika mu fizikisi ngati mlatho wa Wheatstone. Makina a sensor awa amafunikira gudumu la decode kuti agwire bwino ntchito. Mphete yokhala ndi mano ya sensor imadutsa zopinga ziwiri panthawi yosuntha, potero imazindikira mlatho woyezera ndikupanga chizindikiro cha sinusoidal. Kuwerenga zamagetsi - wofananira atembenuza sinusoidal sinusoidal kukhala amakona anayi. Chizindikirochi chikhoza kugwiritsidwa ntchito mwachindunji ndi wolamulira wa ABS kuti awerengenso. Gudumu la decoding lili ndi polarity yosinthira: ma pole a kumpoto ndi kumwera amasinthasintha. Wosanjikiza maginito amakutidwa ndi zokutira mphira. Gudumu la decoding litha kumangidwanso molunjika ku likulu.

Odalirika diagnostics

Pothana ndi zovuta zamakina amakono owongolera ma brake, akatswiri tsopano akufunika, kuwonjezera pakuzindikira mayunitsi owongolera, zida zoyenera kuyesa kachitidwe ka sensa modalirika. Ntchitoyi imachitidwa ndi woyesa watsopano wa ATE AST wochokera ku Continental Teves. Zimakuthandizani kuti muyese mwachangu komanso mosatekeseka masensa othamanga komanso othamanga. M'machitidwe a sensa yogwira ntchito, ndizotheka kulamulira mawilo othamanga popanda kuwachotsa. Pogwiritsa ntchito zingwe zowonjezera, sensa ya ATE AST imatha kuyesanso masensa ena a ATE ESP monga galimoto yotembenuza galimoto, sensor yothamanga, ndi maulendo atali ndi lateral acceleration. Ngati magetsi operekera, chizindikiro chotulutsa ndi pini ya pulagi amadziwika, ndizotheka kusanthula masensa a machitidwe ena agalimoto. Chifukwa cha choyesa cha ATE AST, zowononga nthawi komanso zokwera mtengo za masensa ndi zinthu zina polowa m'malo mwa kuyesa kwawo ndi njira yabwino.

Mulingo woyenera kwambiri processing dongosolo

ATE AST Sensor Tester ili ndi chiwonetsero chachikulu, chosavuta kuwerenga chokhala ndi njira yowunikira kumbuyo. Sensa imayendetsedwa ndi mabatani anayi a zojambulazo olembedwa mwachidziwitso. Ndi chida chothandiza

Kugwira ntchito ndi choyesa cha ATE AST ndikosavuta. Menyuyo idapangidwa m'njira yoti wogwiritsa ntchito adutse njira yonse yowunikira pang'onopang'ono. Choncho simuyenera kuphunzira kwa nthawi yaitali buku la malangizo.

Kuzindikirika kwa sensor yodziwikiratu

Poyesa masensa othamanga ozungulira, makina anzeru amagetsi, atatha kulumikiza ndi kuyatsa tester, amazindikira okha ngati sensa ilibe kapena ikugwira ntchito, m'badwo woyamba kapena wachiwiri. Njira yowonjezereka yoyesera imadalira mtundu wa sensa yomwe imadziwika. Ngati milingo yoyezedwa ichoka pamtengo wolondola, wogwiritsa amapatsidwa malangizo kuti apeze cholakwikacho.

Investment m'tsogolo

Chifukwa cha kukumbukira kwa flash, pulogalamu ya ATE AST sensor tester ikhoza kusinthidwa nthawi iliyonse kudzera pa PC mawonekedwe. Izi zimapangitsa kuti zikhale zosavuta kupanga kusintha kwa malire. Choyesa chothandiza ichi ndi ndalama zolimba zomwe zolakwika za masensa othamanga ndi dongosolo la ESP zitha kuzindikirika mwachangu komanso mwachuma.

Malamulo oyambira ogwiritsira ntchito ma wheel maginito a ABS:

• Osayika gudumu lonyamulira pamalo onyansa,

• Osayika gudumu lokhala ndi mphete ya maginito pafupi ndi maginito okhazikika.

Chidziwitso pakuchotsa sensor wheel yogwira:

• Musalowetse zinthu zakuthwa mu dzenje lomwe sensor ya ABS imayikidwa, chifukwa izi zingawononge mphete ya maginito.

Chidziwitso cha kukhazikitsa Wheel Bearing:

• Dziwani kuti mbali yomwe ili ndi mphete ya maginito imayang'anizana ndi sensa yamagudumu,

• kukwera mayendedwe potengera malingaliro a wopanga kapena wopanga magalimoto,

• Osayendetsa mayendedwe ndi nyundo;

• Kanikizani ma bere pogwiritsa ntchito zida zoyenera,

• Pewani kuwononga mphete ya maginito.
