Kedu ihe bụ Rear ABS Sensor? Kedu ụdị dị na otu esi etinye ha?
A na-eji abs sensọ na ụgbọ ala ABS (Anti-lock Braking System). Na sistemụ ABS, ihe mmetụta inductive na-enyocha ọsọ. Ihe mmetụta abs na-ewepụta akara ngosi eletriki quasi-sinusoidal AC site na ọrụ mgbanaka gia nke na-agbagharị n'otu n'otu na wiil, yana ugboro ya na njupụta ya metụtara ọsọ wheel. A na-ebufe mgbama mmepụta na ngalaba njikwa eletrọnịkị ABS (ECU) iji ghọta oge nleba anya nke ọsọ wiil.
1, Linear wheel ọsọ ihe mmetụta
Ihe mmetụta ọsọ ụkwụ Linear bụ nke mejuputara nke magnet na-adịgide adịgide, axis pole, eriri induction na mgbanaka eze. Mgbe mgbanaka ngwo ahụ na-atụgharị, ọnụ gia na azụ azụ na-atụgharị n'akụkụ axis polar. N'oge ntụgharị nke mgbanaka gia, mgbanaka magnetik dị n'ime eriri induction na-agbanwe ọzọ iji mepụta ike induction electromotive, na mgbama a bụ ntinye aka na njikwa eletrọnịkị nke ABS site na eriri na njedebe nke eriri induction. Mgbe ọsọ nke mgbanaka gia na-agbanwe, ugboro nke ike electromotive a na-ebute na-agbanwekwa.
2, mgbanaka wheel ọsọ ihe mmetụta
Ihe mmetụta ọsọ wheel nke afọ ana-abụkarị nke magnet na-adịgide adịgide, eriri induction na mgbanaka eze. Ihe ndọta na-adịgide adịgide nwere ọtụtụ ụzọ abụọ nke okporo osisi magnetik. N'oge ntụgharị nke mgbanaka gia, mgbanaka magnetik dị n'ime eriri induction na-agbanwe ọzọ iji mepụta ike induction electromotive. Mgbama a bụ ntinye na mpaghara njikwa eletrọnịkị nke ABS site na eriri na njedebe nke eriri induction. Mgbe ọsọ nke mgbanaka gia na-agbanwe, ugboro nke ike electromotive a na-ebute na-agbanwekwa.
3, Hall ụdị wheel ọsọ ihe mmetụta
Mgbe gia dị n'ọnọdụ egosiri na (a), a na-agbasa ahịrị oghere ndọta na-agafe na akụkụ Ụlọ Nzukọ na ebe ndọta adịghị ike; Mgbe gia dị n'ọnọdụ egosiri na (b), ahịrị oghere ndọta na-agafe na akụkụ Ụlọ Nzukọ ahụ na-etinye uche na ebe ndọta siri ike. Mgbe gia na-agbagharị, njupụta nke ike magnetik na-agafe na akụkụ Ụlọ Nzukọ ahụ na-agbanwe, nke na-eme ka voltaji Ụlọ Nzukọ gbanwee, na Ụlọ Nzukọ ahụ ga-emepụta ọkwa millivolt (mV) nke voltaji ebili mmiri quasi-sine. Ekwesịrị ịgbanwe mgbama a site na sekit eletrọnịkị ka ọ bụrụ voltaji pulse ọkọlọtọ.
Wụnye
(1) mgbanaka gia stamping
Mgbanaka nha nha na mgbanaka dị n'ime ma ọ bụ mandrel nke ngalaba hub na-anabata nnyonye anya dabara adaba. N'ime usoro nhazi nke oghere hub, a na-ejikọta mgbanaka nha nha na mgbanaka dị n'ime ma ọ bụ mandrel site na ntinye mmanụ.
(2) Wụnye ihe mmetụta
Ọdabara dị n'etiti ihe mmetụta na mgbanaka mpụta nke ngalaba hub bụ nnyonye anya dabara na mkpọchi nut. The linear wheel ọsọ ihe mmetụta bụ tumadi nut mkpọchi ụdị, na mgbanaka wheel ọsọ ihe mmetụta nakweere nnyonye anya dabara.
Ebe dị anya n'etiti elu dị n'ime nke magnet na-adịgide adịgide na nha nha nha nke mgbanaka: 0.5 ± 0.15 mm (karịsịa site na njikwa nke elu elu nke mgbanaka, n'ime oghere nke ihe mmetụta na concentricity)
(3) Nnwale ule na-eji voltaji mmepụta ọkachamara na-eme onwe ya na waveform n'otu ọsọ ọsọ, na ihe mmetụta linear kwesịrị ịnwale ma obere sekit;
Ọsọ: 900rpm
Ihe achọrọ voltaji: 5.3 ~ 7.9 V
Ihe chọrọ waveform: ebili mmiri kwụsiri ike
