2. Ọrụ silinda brek Master: Nrụgide × Mgbanwe olu Kwa SAE J1601
Sịlinda onye isi brek bụ ihe na-emepụta nrụgide hydraulic nke na-agbanwe ike igwe site na pedal brek (nke ihe na-akwalite ikuku na-enyere aka) ka ọ bụrụ nrụgide hydraulic nke na-arụ ọrụ na cylinders wiil ma ọ bụ calipers. Ụkpụrụ SAE J1601 (Master Cylinder — Vehicular Hydraulic Brake System) na-akọwapụta ihe achọrọ maka nha, arụmọrụ, na ogologo oge maka cylinders ukwu eji na sistemụ brek hydraulic ụgbọala.
A na-achịkwa ọrụ silinda ukwu site na ụkpụrụ atọ dị mkpa: (1) Nha nha nrụgide - nrụgide nke silinda ukwu na-emepụta hà nhata ike pedal nke mpaghara piston kewara, mụbaa site na oke booster na oke pedal, (2) Ngafe olu - olu mmiri brek nke silinda ukwu na-agbanwe site na strok pedal otu nhata mpaghara piston ugboro strok piston, (3) Iwu Pascal - nrụgide nke silinda ukwu na-emepụta hà nhata nrụgide na silinda wiil (na-eche na enweghị mfu nrụgide na ahịrị brek), na-ewepụ obere mfu nrụgide site na esemokwu ahịrị na mmachi dabara adaba (ọ na-abụkarị mfu nrụgide 2-5%).
Mgbanwe olu nrụgide × bụ mkpebi injinịa isi: (1) Dayameta olulu buru ibu = mpaghara piston ka ukwuu = mmụba mmiri mmiri kwa stroke pedal = obere stroke pedal achọrọ maka otu mmegharị piston caliper ahụ, (2) Dayameta olulu buru ibu kwa = mpaghara piston ka ukwuu = obere nrụgide emepụtara kwa ike pedal = mmetụta pedal dị nro na ike pedal dị elu achọrọ.

Oghere kacha mma bụ nke na-edozi mmetụta abụọ ahụ maka njikọta GVWR kpọmkwem, oke pedal, na oke booster.
Mmekọrịta mgbakọ na mwepụ bụ: Ike Pedal × Oke Pedal × Oke Bulite = Nrụgide Ahịrị × Mpaghara Piston × Ọnụọgụ Silinda Wheel / Mmezi Bulite. Maka sistemụ brek gwongworo nkịtị nwere ihe nkwado nke inch 7 (oke bulite 4:1), oke pedal 4:1, na silinda wiil 4 (ma ọ bụ piston caliper 4), mmekọrịta ahụ na-eme ka ọ dị mfe: Ike Pedal × 16 = Nrụgide Ahịrị × Mpaghara Piston. Maka ike pedal 250 N (ike ụkwụ ọkwọ ụgbọala nkịtị maka braking na-adịgide adịgide) na nrụgide ahịrị 80 bar (1,160 psi) nke achọrọ, mpaghara piston achọrọ bụ: 250 N × 16 / 80 bar = 50 mm² kwa wiil, ma ọ bụ mkpokọta 200 mm² maka wiil 4. Dayameta oghere kwekọrọ bụ sqrt (200 mm² / π × 4) ≈ 16 mm, nke dị oke obere. Ihe na-eme ka o doo anya bụ na silinda/caliper wiil ọ bụla na-enwekarị piston abụọ (ma ọ bụ otu piston buru ibu), yabụ na mgbakọ ahụ kwesịrị ịtụle ọnụọgụ silinda wiil ahụ. Ngụkọta edoziri na-enye oke oghere 7/8″ ruo 1-1/4″ maka oke 7T-40T GVWR. A na-enye nhọrọ bul nke GVWR kpọmkwem na matrix mkpebi 7-band dị n'okpuru.

Maka gwongworo 7-ton, a na-enyocha oghere 7/8 inch site na nnwale nnabata ECE R13-H yana nnwale brek oyi na ọkụ. Shaoxing Fangjie Auto Accessory Co., Ltd. na-enye silinda bore master nke dị sentimita 7/8 site na iji ihe owuwu aluminom dị mma nke OEM na akara EPDM nke a tụrụ maka mmiri brek DOT 3, DOT 4, na DOT 5.1.
Q2: Gịnị bụ ihe dị iche n'etiti silinda brek nke aka na nke sekit abụọ?
Ihe dị iche n'etiti silinda aka na nke abụọ nke brek bụ: (1) silinda aka (otu sekit) nke aka — nwere otu piston na otu sekit hydraulic; ọ bụrụ na sekit ahụ ada, brek niile efuola. A na-ejikarị silinda aka na otu sekit naanị n'ụgbọala dị mfe n'okpuru 3.5T GVWR (ụgbọala ndị njem, van ọkụ, gwongworo ọkụ) ma ha adịghịzi arụ ọrụ nke ọma n'ọrụ gwongworo ọgbara ọhụrụ n'ihi iwu nchekwa. (2) Silinda aka na-agba abụọ (tandem) nke aka — nwere piston abụọ n'usoro na sekit hydraulic abụọ nọọrọ onwe ha (nke a na-akpọkarị diagonal split: n'ihu-aka ekpe + azụ-nri na sekit 1, n'ihu-nri + azụ-aka ekpe na sekit 2). Ọ bụrụ na otu sekit ada, sekit nke ọzọ ka na-enye ihe dị ka 50-60% brek na wiil ndị fọdụrụ. ECE R13-H §5.2.1 chọrọ silinda aka na-agba abụọ maka ụgbọala niile dị n'elu 3.5T GVWR (N2, N3, M2, M3 edemede) na maka ụgbọala niile nwere brek hydraulic. (3) Maka ngwa ngwa gwongworo OEM karịrị 3.5T GVWR, cylinder ukwu sekit abụọ dị mkpa. Nhazi nkewa diagonal bụ ihe a na-ahụkarị, mana ụfọdụ OEM na-eji nkewa n'ihu na azụ (sekit ihu + sekit azụ) nke na-enye 70-80% braking na wiil ihu ma ọ bụrụ na sekit azụ ada, ma ọ bụ nke ọzọ.
Q3: Enwere m ike iji silinda ukwu buru ibu iji nweta ike brek karịa?
Mba, ị gaghị eji silinda ukwu buo ibu iji nweta ike brek karịa n'ihi na sistemụ brek bụ sistemu hydraulic mechiri emechi nwere nguzozi nrụgide.
