Sensor ya ABS.
Sensor y'imbere ikoreshwa muri ABS (Sisitemu yo Gufunga Gufunga Ingufu). Muri sisitemu ya ABS, umuvuduko ugenzurwa na sensor iyobora. Sensor y'imbere isohora ibimenyetso by'amashanyarazi bya AC quasi-sinusoidal binyuze mu gikorwa cy'impeta y'ibikoresho izenguruka hamwe n'uruziga, kandi ingano n'uburebure byayo bifitanye isano n'umuvuduko w'uruziga. Ikimenyetso cyoherezwa mu cyuma gicunga amashanyarazi cya ABS (ECU) kugira ngo gikurikirane umuvuduko w'uruziga mu buryo nyabwo.
1, sensor y'umuvuduko w'uruziga rw'umurongo
Sensoreri y'umuvuduko w'amapine igizwe ahanini na sumaku ihoraho, umurongo w'inkingi, induction coil n'impeta y'amenyo. Iyo impeta y'ibikoresho izunguruka, umutwe w'ibikoresho n'inyuma bisimburana bihanganye n'umurongo w'inyuma. Mu gihe cyo kuzenguruka kw'impeta y'ibikoresho, magnetic flux iri muri induction coil irahinduka kugira ngo ikore imbaraga za induction electromotive, kandi iki kimenyetso cyinjizwa mu cyuma gicunga amashanyarazi cya ABS binyuze mu mugozi uri ku mpera ya induction coil. Iyo umuvuduko w'impeta y'ibikoresho uhindutse, inshuro z'imbaraga za electromotive ziterwa nazo zirahinduka.
2, sensor y'umuvuduko w'uruziga rw'impeta
Sensoreri y'umuvuduko w'amapine igizwe ahanini na sumaku ihoraho, induction coil n'impeta y'amenyo. Sumaku ihoraho igizwe n'inkingi nyinshi za sumaku. Mu gihe cyo kuzenguruka kw'impeta y'ibikoresho, sumaku iri imbere muri induction coil irahinduka ubudasa kugira ngo itange imbaraga za electromotive. Iki kimenyetso cyinjizwa mu cyuma gicunga amashanyarazi cya ABS binyuze mu mugozi uri ku mpera ya induction coil. Iyo umuvuduko w'impeta y'ibikoresho uhindutse, inshuro z'imbaraga za electromotive ziterwa nazo zirahinduka.
3, sensor y'umuvuduko w'amapine yo mu bwoko bwa Hall
Iyo vitesi iherereye mu mwanya ugaragara muri (a), imirongo ya rukuruzi inyura muri Hall iratatanye kandi imbaraga rukuruzi ziba nkeya; Iyo vitesi iherereye mu mwanya ugaragara muri (b), imirongo ya rukuruzi inyura muri Hall iba ikungahaye kandi imbaraga rukuruzi ziba zikomeye cyane. Iyo vitesi izenguruka, ubucucike bw'umuyoboro wa rukuruzi unyura muri Hall buhinduka, bigatuma voltage ya Hall ihinduka, maze igice cya Hall gitanga voltage ya millivolt (mV) ya quasi-sine wave. Iki kimenyetso kandi kigomba guhindurwa na electronic circuit mo voltage isanzwe ya pulse.
Shyiramo
(1) Impeta yo gutema ibikoresho
Impeta y'amenyo n'impeta y'imbere cyangwa mandrel by'igice cy'inyuma bihuza neza. Mu gihe cyo guteranya igice cy'inyuma, impeta y'amenyo n'impeta y'imbere cyangwa mandrel bihuzwa hamwe hakoreshejwe imashini itera amavuta.
(2) Shyiramo sensor
Ingano iri hagati ya sensor n'impeta y'inyuma y'igice cy'inyuma ni ukwinjira mu buryo bunyuranyije n'uburyo ...
Intera iri hagati y'ubuso bw'imbere bwa rukuruzi ihoraho n'ubuso bw'amenyo y'impeta: 0.5 ± 0.15 mm (cyane cyane binyuze mu kugenzura umurambararo w'inyuma w'impeta, umurambararo w'imbere w'icyuma gipima amashanyarazi n'uburyo gishyirwa mu mwanya wacyo)
(3) Voltage yo gupima ikoresha voltage y’umwuga yikoreye n’imiterere y’umuvuduko runaka, kandi sensor y’umurongo igomba no gusuzuma niba uruziga rugufi;
Umuvuduko: 900rpm
Ibisabwa kuri Voltage: 5.3 ~ 7.9 V
Ibisabwa ku miterere y'umuraba: umuraba uhamye wa sine
Gupima ingufu z'amashanyarazi
Gutahura amashanyarazi asohoka
Ibintu byo kugenzura:
1, voltage isohoka: 650 ~ 850mv (1 20rpm)
2, imiterere y'umuraba usohoka: umuraba uhamye wa sine
Icya kabiri, ikizamini cyo kuramba kw'imashini ipima ubushyuhe buke mu mubiri (ab sensor)
Bika sensor kuri 40 ° C mu gihe cy'amasaha 24 kugira ngo urebe niba sensor yo mu nda ishobora kuzuza ibisabwa mu mikorere y'amashanyarazi no gufunga ikoreshwa mu buryo busanzwe.
Kuki sensor yo mu nda yoroshye kuyimena
Impamvu zituma sensor ya ABS yoroshye kwangiza harimo igice cy’induction gitwikiriwe, umurongo urekuye n’ubwiza bwa sensor ubwayo. Ibisobanuro birambuye ni ibi bikurikira:
Igice cyo kumva gitwikiriwe: iyo igice cyo kumva cya sensor ya ABS gitwikiriwe n'umwanda, ivumbi cyangwa ibindi bintu by'amahanga, bizabangamira uburyo sensor isohora, bigatuma mudasobwa idashobora gupima neza umuvuduko, ibyo bizagira ingaruka ku mikorere isanzwe ya sisitemu yo gufunga feri.
Umurongo urekuye: Umurongo wa sensor ntabwo ukomeye cyangwa umuhuza urekuye, ibyo bigatuma habaho kwangirika nabi kw'amajwi, bigatera ibibazo bya sisitemu. Ikosa rikunze kubaho ni uko itara ry'ikosa ryaka.
Ubwiza bwa sensor ubwayo: iyo ubwiza bwa sensor ya ABS ari bubi, bishobora kugira ingaruka ku ituze ry'ikimenyetso cyayo cyo gusohora, hanyuma bigatera ingaruka ku buryo sisitemu ya ABS ikora ndetse n'umutekano wo kuyitwara.
Ibi bintu bishobora gutuma sensor ya ABS yangirika byoroshye, bityo mu gihe cyo kuyikoresha no kuyibungabunga, hakwiye kwitabwaho ku isuku ya sensor no kugenzura uko umurongo uhagaze kugira ngo habeho umutekano mu gutwara.
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
Zhuo Meng Shanghai Auto Co., Ltd. yiyemeje kugurisha ibice by'imodoka bya MG & MAUXS.
