Kedu ihe bụ ihe mmetụta ABS nke dị n'azụ? Kedu ụdị dị na ya, kedu ka esi etinye ha?
A na-eji ihe mmetụta abs eme ihe n'ụgbọala moto ABS (Sistemụ Braking Mgbochi Mkpọchi). Na sistemụ ABS, ihe mmetụta inductive na-enyocha ọsọ ya. Ihe mmetụta abs na-ewepụta otu akara eletriki AC quasi-sinusoidal site na ọrụ nke mgbanaka gia nke na-agbagharị na wiil ahụ, ugboro ole ya na oke ya jikọtara ya na ọsọ wiil ahụ. A na-ebufe akara ngosi mmepụta na ngalaba njikwa eletrọnịkị ABS (ECU) iji hụ na a na-enyocha ọsọ wiil ahụ n'oge.
1, ihe mmetụta ọsọ wiil kwụ ọtọ
Ihe mmetụta ọsọ wiilụ kwụ ọtọ bụ magnet na-adịgide adịgide, axis pole, induction coil na mgbanaka ezé. Mgbe mgbanaka gia na-agbagharị, isi gia na azụ na-agbanwe axis pola dị iche. N'oge ntụgharị nke mgbanaka gia, mgbanwe magnet dị n'ime coil induction na-agbanwe n'otu aka ahụ iji mepụta ike electromotive induction, a na-etinyekwa akara a na ngalaba njikwa eletrọniki nke ABS site na eriri dị na njedebe nke coil induction. Mgbe ọsọ nke mgbanaka gia gbanwere, ugboro nke ike electromotive induced na-agbanwekwa.
2, ihe mmetụta ọsọ wiil mgbanaka
Ihe mmetụta ọsọ wiilụ annular bụ magnet na-adịgide adịgide, eriri induction na mgbanaka ezé. Magnet na-adịgide adịgide nwere ọtụtụ ụzọ abụọ nke ogwe magnet. N'oge ntụgharị nke mgbanaka gia, mgbanwe magnet dị n'ime eriri induction na-agbanwe n'otu aka ahụ iji mepụta ike electromotive induction. A na-etinye akara a na ngalaba njikwa eletrọniki nke ABS site na eriri dị na njedebe nke eriri induction. Mgbe ọsọ nke mgbanaka gia gbanwere, ugboro ole ike electromotive induced na-agbanwekwa.
3, Ihe mmetụta ọsọ wiil nke ụdị Hall
Mgbe gia dị n'ọnọdụ egosiri na (a), ahịrị ubi magnetik ndị na-agafe na ihe Hall na-agbasasị, ubi magnetik adịghịkwa ike; Mgbe gia dị n'ọnọdụ egosiri na (b), ahịrị ubi magnetik ndị na-agafe na ihe Hall na-agbakọta ọnụ, ubi magnetik dịkwa ike. Mgbe gia na-agbagharị, njupụta nke ahịrị ike magnetik nke na-agafe na ihe Hall na-agbanwe, nke na-eme ka voltaji Hall gbanwee, ihe Hall ga-ewepụta ọkwa millivolt (mV) nke voltaji ebili mmiri quasi-sine. Ọ dịkwa mkpa ka sekit eletrọnịkị gbanwee akara a ka ọ bụrụ voltaji pulse ọkọlọtọ.
Wụnye
(1) Mgbaaka gia stampụ
Mgbaaka ezé na mgbanaka ma ọ bụ mandrel dị n'ime nke unit hub na-adaba adaba. N'usoro nchikọta nke unit hub, a na-eji igwe nkụnye mmanụ ejikọta mgbanaka ezé na mgbanaka dị n'ime ma ọ bụ mandrel.
(2) Wụnye ihe mmetụta ahụ
Njikọta dị n'etiti sensọ na mgbanaka mpụta nke unit hub bụ nhazi nnyonye anya na mkpọchi nut. Ihe mmetụta ọsọ wiil kwụ ọtọ bụkarị ụdị mkpọchi nut, ihe mmetụta ọsọ wiil mgbanaka na-anabata nhazi nnyonye anya.
Anya dị n'etiti elu ime nke magnet na-adịgide adịgide na elu ezé nke mgbanaka ahụ: 0.5 ± 0.15 mm (karịsịa site na njikwa nke dayameta mpụta nke mgbanaka ahụ, dayameta ime nke ihe mmetụta ahụ na njikọ)
(3) Voltaji nnwale ahụ na-eji voltaji mmepụta ọkachamara na usoro waveform nke aka ya mere n'otu ọsọ, ihe mmetụta linear kwesịkwara ịnwale ma sekit dị mkpụmkpụ ahụ ọ bụ;
Ọsọ: 900rpm
Achọrọ voltaji: 5.3 ~ 7.9 V
Ihe achọrọ maka ụdị Waveform: ebili mmiri sine kwụsiri ike
