Lefapha: Brake Systems - Ithute liphiri tsa li-sensor

Tšehetso ea lichelete: ATE Continental. Sistimi ea sensor ea mabili lits'ebetsong tsa sejoale-joale tsa braking, joalo ka SBD ASR, EDS le ESP, e etselitsoe ho fetisetsa tlhahisoleseling mabapi le palo ea maqhubu a mabili ho molaoli ea loketseng.

E ngotsoe ho litsamaiso tsa Brake

Boto ea Bahlokomeli: ATE Continental

Ha tlhahisoleseding e nepahetseng haholoanyane eo tsamaiso ena e e tlalehang, e ntlafatsa le ho phutholoha haholoanyane, e leng se bolelang hore tsamaiso ea braking e phethahetse le ho tšoarella haholoanyane.

Sensor e sa sebetseng (inductive).

Lilemong tsa pele tsa litsamaiso tsa ABS, ho ne ho lekane hore li-sensor tsa mabili li fane ka letšoao ho tloha ha lebelo le fihla ho lik'hilomithara tse ka bang 7. Ka mor'a hore ABS e atolosoe ka mesebetsi e eketsehileng, e kang: ASR, EDS le ESP. , ho ile ha hlokahala hore moqapi o ka fetisa letšoao le feletseng. Li-sensor tsa Passive li ile tsa ntlafatsoa hore li tsebe ho tseba lebelo le tlase ho 3 km / h, empa sena e ne e le moeli oa bokhoni ba bona.

Sensor e sebetsang (magnetic resistance)

Li-sensor tse sebetsang tsa moloko o mocha li lemoha lebelo ho tloha ho 0 km/h ka lekhetlo la pele. Haeba re bapisa litsamaiso tse peli tsa sensor, re ka bona hore li-sensor tse sa sebetseng li se li hlahisitse lets'oao la sinusoidal. Letšoao lena le ile la sebetsoa ke balaoli ba ABS hore e be leqhubu la lisekoere, hobane ke matšoao a joalo feela a lumellang balaoli ho etsa lipalo tse hlokahalang. Ke mosebetsi ona oa balaoli ba ABS - ho fetola lets'oao la sinusoidal ho quadrilateral - le fetisetsoang ho sensor e sebetsang ea lebili. Sena se bolela: sensor e sebetsang e hlahisa pontšo ea litsela tse 'nè, e sebelisoang ka ho toba ke sehlopha sa taolo ea ABS bakeng sa lipalo tse hlokahalang. Boleng ba lets'oao la sensor bakeng sa molumo, lebelo la mabili le lebelo la koloi ha bo fetohe.

Moralo le ts'ebetso ea sensor ea passive.

Sensor inductive e na le lipoleiti tsa makenete tse pota-potiloeng ke khoele. Lipheletso ka bobeli tsa khoele li hokahane le ABS molaoli. Sesebelisoa sa selikalikoe sa ABS se sebakeng sa hub kapa driveshaft. Ha lebili le ntse le potoloha, mela ea matla a khoheli ea sensor ea lebili e kenella ka har'a selikalikoe sa meno sa ABS, e leng se etsang hore ho hlahisoe voltage ea sinusoidal (e susumelitsoeng) ka har'a sensor ea lebili. Ka liphetoho tse sa khaotseng: ho robeha ha meno, ho robeha ha meno, ho hlahisoa khafetsa, e fetisetsoang ho molaoli oa ABS. Leqhubu lena le itšetlehile ka lebelo la lebili.

Sebopeho le mesebetsi ea kutlo e sebetsang

Sensor ea magnetoresistive e na le li-resistors tse 'ne tse ka nkeloang sebaka.

magnetically, mohloli oa motlakase le comparator (amplifier ea motlakase). Molao-motheo oa ho lekanya ka lihanyetsi tse 'ne o tsejoa ho fisiks e le borokho ba Wheatstone. Sistimi ena ea sensor e hloka lebili la decode ho sebetsa hantle. Rele ea meno ea sensor e koahelang lihanyetsi tse peli nakong ea ho sisinyeha, ka hona e lemoha borokho ba ho lekanya le ho etsa lets'oao la sinusoidal. Ho bala lisebelisoa tsa elektronike - papiso e fetola lets'oao la sinusoidal hore e be e khutlonnetsepa. Letšoao lena le ka sebelisoa ka ho toba ke molaoli oa ABS bakeng sa lipalo tse eketsehileng. Lebili la li-decoding le na le polarity e fapaneng: lipalo tsa leboea le boroa lia fapanyetsana. Lera la magnetized le koahetsoe ka seaparo sa rabara. Lebili la decoding le lona le ka hahuoa ka kotloloho ho hub.

Litlhahlobo tse tšepahalang

Ha ho rarolloa litsamaiso tsa sejoale-joale tsa ho laola mariki, litsebi joale li hloka, ntle le ho hlahloba likarolo tsa taolo, lisebelisoa tse nepahetseng ho leka lits'ebetso tsa sensor ka nepo. Mosebetsi ona o etsoa ke mohlahlobi e mocha oa ATE AST oa Continental Teves. E u lumella ho lekola li-sensor tsa lebelo la mabili kapele le ka mokhoa o sireletsehileng. Lits'ebetsong tsa sensor tse sebetsang, hoa khoneha ho laola mabili a susumetsang ntle le ho a tlosa. Ho sebelisa sete e atolositsoeng ea lithapo, sensor ea ATE AST e ka boela ea leka li-sensor tse ling tsa ATE ESP tse kang koloi ea koloi, sensor ea khatello, le li-longitudinal le lateral acceleration sensors. Haeba motlakase oa phepelo, lets'oao la tlhahiso le kabelo ea plug ea plug li tsejoa, hoa khoneha ho sekaseka li-sensor tsa litsamaiso tse ling tsa koloi. Ka lebaka la tlhahlobo ea ATE AST, tlhahlobo e jang nako le e theko e boima ea li-sensor le likarolo tse ling ka phetoho ea tsona ea liteko

Mokhoa o nepahetseng oa ho sebetsa

ATE AST Sensor Tester e na le ponts'o e kholo, e bonolo ho bala, e nang le khetho ea ho bulela lebone la morao. Sensor e laoloa ke likonopo tse 'ne tsa foil tse ngotsoeng ka mokhoa o hlakileng. Ke sesebelisoa se sebetsang

phepelo ea motlakase ho tsoa marang-rang a onboard ea koloi Ho sebetsa le tlhahlobo ea ATE AST ho bonolo haholo. Lenane le entsoe ka tsela eo mosebelisi a fetang ka har'a ts'ebetso eohle ea tlhahlobo mohato ka mohato. Kahoo ha ho hlokahale hore u ithute bukana ea litaelo ka nako e telele.

Kamohelo ea kutlo e iketsang

Ha u lekola li-sensor tsa lebelo la ho potoloha, sistimi e bohlale ea elektroniki, kamora ho hokela le ho bulela tester, e lemoha ka bo eona hore na sensor ha e sebetse kapa e sebetsa, moloko oa pele kapa oa bobeli. Ts'ebetso e eketsehileng ea tlhahlobo e ipapisitse le mofuta oa sensor e amoheloang. Haeba litekanyetso tse lekantsoeng li kheloha ho boleng bo nepahetseng, mosebelisi o fuoa malebela a ho fumana phoso.

Tsetelo nakong e tlang

Ka lebaka la memori ea flash, software ea ATE AST sensor tester e ka ntlafatsoa ka nako efe kapa efe ka sebopeho sa PC. Sena se etsa hore ho be bonolo ho etsa liphetoho ho litekanyetso tsa moeli. Ka hona, teko ena e sebetsang ke letsete le tiileng le ka bonang liphoso ka potlako le ka moruo ho li-sensor tsa lebelo la mabili le tsamaiso ea ESP.

Melao ea mantlha ea ho sebetsa le li-bearings tsa mabili a makenete a ABS:

• u se ke ua beha koloi ea lebili sebakeng se litšila sa mosebetsi;

• Se ke oa beha lebili le nang le selikalikoe sa makenete haufi le makenete oa kamehla.

Tlhokomeliso mabapi le ho tlosa sensor ea mabili e sebetsang:

• U se ke ua kenya lintho tse hlabang ka mokoting oo ho kenngoeng sensor ea ABS, kaha sena se ka senya lesale la makenete.

Tlhokomeliso ea ho kenya lebili:

• hlokomela hore lehlakore le nang le selikalikoe sa makenete le shebane le sensor ea lebili,
