Ahịrị ihe mmetụta ABS n'ihu
A na-eji ihe mmetụta abs eme ihe na ABS (Sistemụ Braking Mgbochi Mkpọchi) nke ụgbọala. A na-eji ihe mmetụta inductive na-enyocha ọtụtụ sistemụ ABS iji nyochaa ọsọ ụgbọ ala. Ihe mmetụta abs na-ewepụta otu nke ziri ezi Ugboro na oke nke mgbaàmà mgbanwe ugbu a nke sinusoidal metụtara ọsọ wiil. A na-ebufe ihe mgbaàmà 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, ogwe osisi, eriri induction na gia mgbanaka. Mgbe gia mgbanaka na-agbagharị, elu ezé na azụ azụ na-eche ihu na axis polar n'otu ụzọ. N'oge ntụgharị nke gia mgbanaka, mmụba magnet dị n'ime eriri induction na-agbanwe n'otu ụzọ iji mepụta ike electromotive induction, a na-etinyekwa akara a na ngalaba njikwa eletrọniki ABS site na eriri dị na njedebe nke eriri induction. Mgbe ọsọ nke gia mgbanaka gbanwere, ugboro ole ike electromotive induced induction na-agbanwekwa.
2. Ihe mmetụta ọsọ wiil mgbanaka
Ihe mmetụta ọsọ wiil annular bụ magnet na-adịgide adịgide, eriri induction na gia mgbanaka. Magnet na-adịgide adịgide nwere ọtụtụ ụzọ abụọ nke ogwe magnet. N'oge ntụgharị nke gia mgbanaka, 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 ABS site na eriri dị na njedebe nke eriri induction. Mgbe ọsọ nke gia mgbanaka gbanwere, ugboro ole ike electromotive induced na-agbanwekwa.
3. Ihe mmetụta ọsọ wiilụ nke Hall
Mgbe gia dị n'ọnọdụ egosiri na (a), ahịrị ike magnetik na-agafe na ihe Hall na-agbasasị, ebe magnetik na-adịghịkwa ike; ebe mgbe gia dị n'ọnọdụ egosiri na (b), ahịrị ike magnetik na-agafe na ihe Hall na-agbakọta, ebe magnetik na-adịkwa ike. Mgbe gia na-agbagharị, njupụta nke mmiri magnetik na-agafe na ihe Hall na-agbanwe, si otú a na-akpata mgbanwe na voltaji Hall, ihe Hall ga-ewepụta voltaji ebili mmiri quasi-sine nke ọkwa millivolt (mV). Ọ dịkwa mkpa ka a gbanwee akara ngosi a ka ọ bụrụ voltaji pulse ọkọlọtọ site na sekit eletrọniki.
Wụnye Mgbasa Ozi Dezie
(1) Gia mgbanaka stampụ
Gia mgbanaka na mgbanaka dị n'ime ma ọ bụ mandrel nke unit hub na-enweta njikọ nnyonye anya. N'oge nhazi nke unit hub, a na-eji igwe hydraulic press ejikọta gia mgbanaka na mgbanaka dị n'ime ma ọ bụ mandrel ahụ;
(2) Wụnye ihe mmetụta ahụ
E nwere ụdị mmekorita abụọ dị n'etiti ihe mmetụta na mgbanaka mpụta nke unit hub: nhazi nnyonye anya na mkpọchi mkpụrụ. Ihe mmetụta ọsọ wiil linear na-abụkarị n'ụdị mkpọchi mkpụrụ, ihe mmetụta ọsọ wiil annular na-anabata nhazi nnyonye anya;
Anya dị n'etiti elu ime nke magnet na-adịgide adịgide na elu ezé nke gia mgbanaka: 0.5±0.15mm (a na-ahụ ya nke ọma site na ijikwa dayameta mpụta nke gia mgbanaka, dayameta ime nke ihe mmetụta na concentricity)
(3) Nwale voltaji Jiri voltaji mmepụta ọkachamara na ụdị waveform nke aka gị mere n'otu ọsọ, ma nwalee ma enwere sekit dị mkpirikpi maka sensọ linear;
Ọsọ: 900rpm
Achọrọ voltaji: 5. 3~7.9v
Ihe achọrọ maka ụdị Waveform: ebili mmiri sine kwụsiri ike

Nchọpụta voltaji mmepụta
Ihe nnwale:
1. Voltaji mmepụta: 650~850mv(1 20rpm)
2. Ọdịdị ebili mmiri mmepụta: ebili mmiri sine kwụsiri ike
Nke abụọ, ule siri ike nke obere okpomọkụ sensọ abs
Debe ihe mmetụta ahụ na 40°C ruo awa 24 iji lelee ma ihe mmetụta afọ ọ bụla ka nwere ike imezu ihe achọrọ maka arụmọrụ eletriki na mkpuchi maka ojiji nkịtị.
