Ngā mea ka akohia e koe i tēnei tuhinga:te mahi a te rango matua parai me te tauwhitinga pēhanga × rōrahi mō ia SAE J1601, ngā roopu GVWR e 7 me ngā diameter poka e rite ana mai i te 3.5T ki te 40T, ko te ahua o te pētera e 4 e pā ana ki tua atu i te diameter poka e whakatau ana i te whakamarie me te haumaru o te taraiwa, ngā hapa e 5 e mahia ana e ngā OEM taraka i te wā e rahi ana te rango matua, ngā whakaritenga tono e 6 mō te tohu i te diameter poka rango matua i roto i te hoko OEM, te whakatau rango matua ā-ringa me te rua-ara iahiko mō ia ECE R13-H §5.2.1, me ngā pātai e 6 e pā ana ki te rahi o te rango matua parai. Mena kei te aromatawai koekōwhiringa diameter o te pūwero matua o te paraimō te raina taraka OEM i roto i te awhe 7T-40T GVWR, koinei te tohutoro hangarau mō te whakatau rahi.
Ko te kupu whakataki pono mai i te tīma hangarau o Shaoxing Fangjie:Ko te whakatau i te rahi o te puoto matua parai te hapa hangarau tino kitea i roto i te hanga taraka OEM. Ko te poka iti rawa ka puta te kore tutuki i te ECE R13-H me te whakahokinga ohorere; ko te poka nui rawa ka puta ngā amuamu a ngā taraiwa mō te ahua ngohengohe o te pedal me te roa o te whiu. Me whakatau te whakatau i runga i te roopu GVWR, kaua i runga i te manakohanga o te kahui waka, i runga rānei i te arotau utu. Ka hangaia e mātou ngā puoto matua i tō mātou whare Shaoxing me ngā diameter poka mai i te 3/4″ ki te 1-1/4″ e kapi ana i te whānuitanga GVWR taraka katoa, ā, ka tohaina e mātou tēnei aratohu rahi ki te marea nā te mea e hiahia ana mātou kia whakatau tika ā mātou kiritaki OEM i te whakatau rahi i te wā tuatahi - kaua e kitea te hapa i te whakamātautau whakaae momo. Ko tā mātou e whai ake nei ko te tohutoro hangarau e tohaina ana e mātou ki ngā tīma hangarau OEM taraka Turkish, Īnia, Āhia ki te Tonga-mā-rāwhiti, me Haina i te wā e pātai ana rātou "he aha te diameter poka e hiahiatia ana e au mō taku taraka 7-tana / 12-tana / 18-tana / 26-tana?"
Mai i te tau 2003, kua neke atu i te 20 tau te roa o tā mātou tīma e tuku ana i ngā wāhanga pūnaha parai taraka ki ngā kaihokohoko muri-mākete o Ūropi, o Āhia ki te Tonga-mā-rāwhiti, me te Rawhiti-waenganui. I ia rā, ka mahi tahi mātou me tā mātou tīma kaimahi neke atu i te 100 me te tīma hokohoko ke 10-tangata ki te hanga i ngā calipers parai, ngā whakatikatika slack, ngā takirere solenoid, me ngā rūma parai. I roto i ngā tau e 5 kua pahure ake nei, kua tukuna e mātou ngā rango matua ki ngā raina taraka OEM 12 i Turkey, Īnia, Vietnam, me te Rawhiti-waenganui, ā, ko te whakatau rahi rango matua te tono whakawhitiwhiti hangarau tino noa mai i ēnei kiritaki. Ko tēnei tuhinga te tohutoro mara i tangohia mai i aua kaupapa OEM 12.
1. I te wā i rahua ai te taraka māmā 7-Tana a te OEM Turkish ki te whakatutuki i ngā whakaritenga ECE R13-H mō te poka iti rawa
I whakahaerehia te whakamātautau whakaae momo ECE R13-H i UTAC France (te mana whakahaere whakaae momo Wīwī) i te Oketopa 2024. I uru atu ki te whakamātautau te whakamātautau whai huatanga o te pēki makariri (ECE R13-H §5.2.2.5) i te pāmahana taiao -10°C me te whakamātautau whai huatanga o te pēki wera (ECE R13-H §5.2.2.6) i muri i te pēki memeha. I rahua te whakamātautau makariri: kāore i taea e te rango matua te neke i te wai pēki kia nui hei whakaoho i ngā rango wira e 4 katoa i roto i te rohe whiu pēti kua tohua o te 75% o te haerenga pēti mōrahi. Ko te pēhanga raina i te 75% o te haerenga pēti he 65 pae, he iti iho i te 80 pae iti rawa e hiahiatia ana mō te whakamātautau makariri. I rahua anō te whakamātautau wera: i muri i te pēki memeha, i eke te pāmahana wai pēki ki te 120°C, ā, i heke te pēhanga raina ki te 55 pae nā te whakahekenga o te matotoru o te wai.
Ko te pūtake ko te iti o te pū 5/8″. Ko te pū 5/8″ he 0.307 in² (198 mm²) noa iho te horahanga piston, ā, i te 7,200 kg GVWR ka puta he koretake o te nekehanga wai mō ia whiunga pēra. Ko te pū 7/8″ (koinei te rahi tika mō te 7T-12T GVWR mō ia SAE J1601) he 0.601 in² (388 mm²) te horahanga piston, he 96% te nui ake o te horahanga piston, ā, ka taea te neke atu i te 96% te nui ake o te wai mō ia whiunga pēra. Kāore te tīma hangarau o te OEM i whakahou i te diameter pū i te wā i whakanuia ai te GVWR mai i te 5T ki te 7T, i runga i te whakaaro "ka mahi te taraka nui ake, te pūnaha parai kotahi". He hē te whakaaro.
Ko te whakatikatika i mahia ko: (1) te whakakapi i te rango matua 5/8″ ki te rango matua 7/8″ (i tukuna e Shaoxing Fangjie he 500 ngā waeine o ngā rango matua 7/8″ i roto i ngā wiki e 4), (2) te whakahou i te tuhinga whakatakotoranga rango matua a te OEM kia rite ki te SAE J1601 mō te kōwhiringa diameter rango mō ia roopu GVWR, (3) te tuku anō i te whakamātautau whakaae momo ECE R13-H me te rango matua hou, i paahitia i te Hanuere 2025. Ko te utu katoa o te whakatikatika tata ki te EUR 28,000 tae atu ki te whakakapinga rango matua, ngā utu whakamātautau anō, me te whakaroa kaupapa 3-marama. Ko te akoranga, i roto i ngā kupu a te miihini matua OEM o Turkey: "e kore rawa mātou e whakaaro anō ki te 'taraka nui ake, pūnaha parai kotahi'. Me ine te diameter rango kia rite ki te roopu GVWR, ā, ko ngā aratohu SAE J1601 te tohutoro hangarau."
Ko te take i tohaina ai e tā mātou tīma tēnei rangahau take, ehara i te mea ahurei te hapa a te OEM o Turkey. E kite ana mātou i tēnei tauira e puta tonu ana puta noa i te hanga taraka OEM puta noa i te ao — ka tīpakohia te diameter o te poka i runga i te tauira o mua, kaua ki te GVWR o nāianei, ā, ka rahua te poka iti i te whakamātautau whakaae momo. Ka whakamāramahia ngā roopu GVWR e 7, te matihiko whakatau diameter poka, me ngā whakaritenga tuku tono e 6 i raro nei hei āwhina i ngā tīma hangarau OEM kia karo i tēnei hapa.
2. Mahi Pūwero Matua Pēhi: Tauhokohoko Pēhanga × Rōrahi Mō ia SAE J1601
Ko te rango matua parai he kaihanga pēhanga waipēhi e huri ana i te kaha miihini mai i te pētera parai (me te āwhina a te whakakaha korehau) hei pēhanga waipēhi e whakaoho ana i ngā rango wira, i ngā caliper rānei. Ko te paerewa SAE J1601 (Rango Matua — Pūnaha Parai Waipēhi Waka) e tohu ana i ngā whakaritenga ā-rahi, ā-mahi, me te pakari mō ngā rango matua e whakamahia ana i roto i ngā pūnaha parai waipēhi waka.
E toru ngā mātāpono matua e whakahaeretia ana mō te mahi a te rango matua: (1) Taurite pēhanga — ko te pēhanga i hangaia e te rango matua he ōrite ki te kaha o te pētara i wehea ki te horahanga o te piston, i whakareatia ki te ōwehenga whakanui me te ōwehenga o te pētara, (2) Te nekehanga rōrahi — ko te rōrahi o te wai parai i nekehia e te rango matua mō ia whiunga pētara he ōrite ki te horahanga piston i whakareatia ki te whiunga piston, (3) Te ture a Pascal — ko te pēhanga i hangaia i te rango matua he ōrite ki te pēhanga i ngā rango wira (ki te kore he ngaronga pēhanga i roto i ngā raina parai), engari kāore i te ngaronga pēhanga iti mai i te waku raina me ngā here whakauru (ko te tikanga he 2-5% te ngaronga pēhanga).
Ko te tauwhitinga pēhanga × rōrahi te whakatau matua a te miihini: (1) He whānui ake te pū = he nui ake te horahanga piston = he nui ake te nekehanga wai mō ia whiunga pedal = he iti ake te whiunga pedal e hiahiatia ana mō te nekehanga piston caliper kotahi, (2) He whānui ake hoki te pū = he nui ake te horahanga piston = he iti ake te pēhanga i hangaia mō ia kaha pedal = he ngawari ake te ahua o te pedal me te kaha pedal teitei ake e hiahiatia ana. Ka mahi ngā pānga e rua i ngā taha rerekē: ka pai ake te pānga rōrahi ki te pū nui ake, engari ka pai ake te pānga pēhanga ki te pū iti ake. Ko te pū tino pai ko te mea e taurite ana i ngā pānga e rua mō te GVWR motuhake, te ōwehenga pedal, me te huinga ōwehenga whakanui.
Ko te whanaungatanga pāngarau ko: Te Kaha o te Peka × Te Ōwehenga o te Peka × Te Ōwehenga Whakakaha = Te Pēhanga Raina × Te Horahanga Piston × Te Tatau o te Puoto Wira / Te Whai Hua o te Whakakaha. Mō tētahi pūnaha pēki taraka noa me te whakakaha 7-inihi (ōwehenga whakakaha 4:1), te ōwehenga peka 4:1, me ngā puoto wira e 4 (ngā piston caliper rānei e 4), ka māmā ake te whanaungatanga ki: Te Kaha o te Peka × 16 = Te Pēhanga Raina × Te Horahanga Piston. Mō te kaha peka 250 N (te kaha waewae taraiwa noa mō te pēki tonu) me te pēhanga raina whāinga 80 pae (1,160 psi), ko te horahanga piston e hiahiatia ana ko: 250 N × 16 / 80 pae = 50 mm² mō ia wira, 200 mm² rānei te tapeke mō ngā wira e 4. Ko te diameter poka e rite ana ko te sqrt(200 mm² / π × 4) ≈ 16 mm, he iti rawa. Ko te tauwehenga whakatikatika ko ia puoto wira/caliper he 2 ngā piston (he piston nui rānei), nō reira me whai whakaaro te tatau ki te maha o ngā puoto wira. Nā te tātaitanga kua whakatikatikaina ka puta te whānuitanga o te poka 7/8″ ki te 1-1/4″ mō te whānuitanga 7T-40T GVWR. Ko te kōwhiringa poka tika mō ia GVWR kei roto i te matihiko whakatau 7-roopu i raro nei.
3. Te Whakataunga o te Diameter Poka: 7 Ngā Rōpū GVWR mai i te 3.5T ki te 40T
| # | Te Rōpū GVWR | Te Diameter o te Pū (inihi / mm) —mō ia SAE J1601 | Rohe Piston | Momo Waka Noa |
|---|---|---|---|---|
| 1 | 3.5T-7.5T | 3/4″ (19.05 mm) | 0.442 inihi² (285 mm²) | Ngā taraka māmā, ngā waka iti, ngā waka arumoni māmā |
| 2 | 7.5T-12T | 7/8″ (22.2 mm) | 0.601 inihi² (388 mm²) | Ngā taraka waenga (Isuzu NPR, Hyundai Mighty, Fuso Canter) |
| 3 | 12T-18T | 1″ (25.4 mm) | 0.785 inihi² (507 mm²) | Ngā taraka taumaha (tohatoha mahi-waenga) |
| 4 | 18T-26T | 1-1/8″ (28.6 mm) | 0.994 inihi² (641 mm²) | Ngā taraka taumaha (te kawe waka ā-rohe, te hanga whare) |
| 5 | 26T-40T | 1-1/4″ (31.75 mm) | 1.227 inihi² (792 mm²) | Ngā taraka taumaha (haerenga roa, keri maina) |
| 6 | 40T-60T | 1-3/8″ (34.9 mm) | 1.485 inihi² (958 mm²) | Ngā taraka taumaha + ngā wakatō (B-takirua, tereina rori) |
| 7 | 60T+ | 1-1/2″ (38.1 mm) nui ake rānei | 1.767 inihi² (1140 mm²) | Ngā taraka kawe taumaha motuhake, ngā taraka keri |
Ko ngā roopu GVWR e 7 e rite ana ki ngā whakarōpūtanga waka noa i roto i ngā mākete taraka o Ūropi, Amerika Te Raki, me Āhia. Ko te kōwhiringa diameter poka i roto i ia roopu e ahu mai ana i: (1) te nekehanga wai e ranea ana mō te whai huatanga o te pēki makariri e ai ki te ECE R13-H §5.2.2.5, (2) te pēhanga raina e ranea ana mō te whai huatanga o te pēki wera e ai ki te ECE R13-H §5.2.2.6 i muri i te pēki memeha, (3) te kaha o te pēke i roto i te awhe 200-350 N mō te pēki tonu (te whakamarie o te taraiwa), (4) te whiu pēke i roto i te 75% o te rohe haere pēke mōrahi e ai ki te ECE R13-H §5.2.1.5 (te tutuki). Me tutuki ngā whakaritenga e 4 i te wā kotahi; ka tīpakohia te diameter poka hei taurite i ngā whakaritenga e 4 katoa.
Mō te hanga taraka OEM, ko ngā roopu GVWR tino noa ko te #2 (7.5T-12T) me te #3 (12T-18T), e rite ana ki ngā kāwai taraka arumoni māmā me te reo tino noa. Ka tukuna e Shaoxing Fangjie ngā rango matua poka 7/8″ (roopu #2) me ngā rango matua poka 1″ (roopu #3) hei SKU e rua tino nui te rahinga i roto i tā mātou raina hua rango matua. Ka tukuna te rango matua poka 1-1/8″ (roopu #4) mō ngā tono taraka kawe taumaha me te hanga mahi ā-rohe, ā, ka tukuna te rango matua poka 1-1/4″ (roopu #5) mō ngā tono haere roa me te keri maina.
4. 4 Ngā Āhuatanga o te PahikaraTe Diameter o te Pūaha i tua atu
Ko te āhua o te pēra — te āhua o te pēra ki te taraiwa i te wā e pēra ana i te pēra noa me te wā ohorere — e whakatauhia ana e ngā āhuatanga e whā i tua atu i te whānui o te pū. He mea nui te āhua o te pēra mō te whakaae a te taraiwa me te haumaru (ka taea e te āhua ngawari o te pēra te mea ka pupuhi koretake ngā taraiwa i ngā pēra, ka whakaiti i te whai huatanga o te pēra i roto i te maha o ngā waka kua whakauruhia ki te ABS).
| # | Te Āhua o te Pahikara | Awhe | Pānga ki te Āhua o te Paera | Whakatakotoranga OEM |
|---|---|---|---|---|
| 1 | Te ōwehenga o te pēra | 3:1 ki te 6:1 | Te ōwehenga teitei ake = te kaha iti o te pētera engari te kaha ake o te whiu pētera | 4:1 noa mō ngā tono taraka |
| 2 | Rahi whakanui | 7 inihi ki te 11 inihi te whānui | He nui ake te whakakaha = he nui ake te ōwehenga whakakaha = he iti ake te kaha o te pētera | 7-9 inihi mō ngā taraka mama, 9-11 inihi mō ngā taraka taumaha |
| 3 | Te roa o te tokotoko pana | 50-150 mm | He roa ake te tokotoko pana = he nui ake te whiu o te pētera e wātea ana | Taurite ki te ōwehenga pētera me te whiu whakanui |
| 4 | Koki pana | 0-15° | Koki nui ake = te kaha o te pētera e ngaro ana ki te kawenga taha | Puritia te pāmahana i raro i te 5° kia pai ai te āhua |
Ka taunekeneke ngā āhuatanga o te ahua o te pēra e whā ki te whānui o te pūwero hei whakatau i te āhua whānui o te pūnaha parai. Ko te taunekeneke ko: (1) Ka whakatau ngātahi te ōwehenga o te pēra me te whānui o te pūwero i te whanaungatanga kaha pēra me te pēhanga raina — ka taea e te ōwehenga pēra teitei ake te whakakapi i te pūwero nui ake hei pupuri i te kaha pēra kotahi, engari i te utu mō te roa o te whiu pēra, (2) Ka whakatau ngātahi te rahi o te whakakaha me te whānui o te pūwero i te whanaungatanga ōwehenga whakakaha me te rohe piston — ka taea e te whakakaha nui ake te whakakapi i te pūwero nui ake, engari i te utu mō te nui ake o te kai hau whakakaha me te puhoi o te urupare whakakaha, (3) Ka whakatau ngātahi te roa o te Pushrod me te ōwehenga pēra i te whanaungatanga haere pēra me te whiu piston rango matua — me roa te pushrod kia taea ai te whiu piston rango matua katoa i te haere katoa o te pēra, (4) Ka pā te koki Pushrod ki te kawenga taha i runga i te piston rango matua, ka taea te whakararu i te hiri wawe mena he nui rawa te koki. Me whakataurite ngā taunekeneke e 4 e te miihini pūnaha parai a te OEM i te wā whakauru waka.
Ko te hapa OEM tino kitea i roto i ngā āhuatanga e 4 ko te kore e ōrite te rahi o te whakakaha ki te whānui o te poka. He pai te whakakaha 7-inihi (ōwehenga whakakaha 4:1) mō ngā rango matua poka 7/8″ (rōpū #2), engari kāore e ranea mō ngā rango matua poka 1-1/8″, 1-1/4″ rānei (rōpū #4 me te #5). Me 9-11″ te whānui o te rahi whakakaha taraka taumaha (ōwehenga whakakaha 5-7:1) hei utu mō te whānui poka nui ake. Me tohu e te OEM te rahi whakakaha e ai ki te whānui poka me te GVWR, kaua e ai ki te rahi miihini, ki te wāhi kāpata rānei.

| N3 (ngā taraka taumaha) | Neke atu i te 12T | Ara-rua (e hiahiatia ana) | ECE R13-H §5.2.1 |
I roto i te mahi, kua tawhito te rango matua kotahi-ara iahiko (ā-ringa) i roto i ngā tono taraka me ngā pahi hou i runga ake i te 3.5T GVWR. Tērā pea ka kitea tonu te rango matua kotahi-ara iahiko i roto i: (1) ngā tauira taraka tawhito rawa (i mua i te tau 1990) kāore anō kia whakahoutia, (2) ētahi waka motuhake i waho o te huarahi (hei tauira, ngā taraka keri, ngā tarakihana tauranga) e whakamahi ana i ngā pūnaha waipēhi, hau rānei, (3) ētahi waka hōia e whakamahi ana i ngā pūnaha wehewehe mua-muri motuhake. Mō ngā taraka OEM katoa i runga ake i te 3.5T GVWR i te tau 2026, me whakamahi te rango matua takirua-ara iahiko.
Ko te wehenga whakarara (mua-maui + muri-matau i te ara iahiko 1, mua-matau + muri-maui i te ara iahiko 2) te whirihoranga ara iahiko-rua tino noa nā te mea ka whakaratohia he aukati taurite i ngā taha e rua o te waka mena ka rahua tetahi o ngā ara iahiko. Ko te wehenga mua-muri (ara iahiko mua + ara iahiko muri) he iti ake te noa i roto i ngā tono taraka hou nā te mea ka whakaratohia he aukati 70-80% i runga i ngā wira o mua mena ka rahua te ara iahiko o muri, engari 20-30% anake te aukati mena ka rahua te ara iahiko o mua (nā te mea ko te nuinga o te kaha aukati kei runga i ngā wira o mua). Ko te wehenga whakarara te whirihoranga e tukuna ana e mātou hei paerewa mō ā mātou rango matua, engari ka taea hoki e mātou te whakarato i ngā whirihoranga wehenga mua-muri i runga i te tono mō ngā kiritaki OEM me ngā whakaritenga hoahoa motuhake.
8. Ngā Pātai Auau: 6 Ngā Pātai mō te Rahi o te Pūwero Matua o te Pēki
P1: He aha te whānui o te poka e tika ana kia whakamahia e te rango matua o te taraka mama 7-tana?
Me whakamahi he rango matua 7-tana (GVWR 6,000-8,500 kg) he diameter poka 7/8 inihi (22.2 mm) e ai ki ngā aratohu rahi a te SAE J1601. Ko te poka 7/8 inihi te paerewa mō ngā taraka arumoni māmā, ā, he hototahi ki ngā servo korehau whakanui 7-9 inihi noa me ngā pūnaha waipēhi porowhita-kotahi, porowhita-rua rānei. Ka whakaratohia e te poka 7/8 inihi he horahanga piston 0.387 in² (250 mm²) e whakaputa ana i te pēhanga raina tata ki te 1,000-1,200 psi (70-85 pae) i te kaha pēhi 250-300 N me te whakanui 7-inihi. Mō ngā taraka 7-tana, ka manatokohia te poka 7/8 inihi e te whakamātautau hanganga ture ECE R13-H me te whakamātautau memeha parai makariri me te wera. E whakarato ana a Shaoxing Fangjie Auto Accessory Co., Ltd. i ngā rango matua 7/8 inihi te whānui me te whare koranu konumohe kounga-OEM me ngā hiri EPDM kua whakatauria mō ngā wai pēki DOT 3, DOT 4, me te DOT 5.1.
Q2: He aha te rerekētanga i waenga i te rango matua parai ā-ringa me te rango matua parai ara-rua?
Ko te rerekētanga i waenga i te rango matua parai ā-ringa me te rango matua porowhita-rua ko: (1) Te rango matua ā-ringa (porowhita-kotahi) — he kotahi te piston me te kotahi te porowhita waipēhi; ki te kore e pai te porowhita, ka ngaro katoa te parai. Ko ngā rango matua porowhita-kotahi ka whakamahia noa i runga i ngā waka māmā i raro i te 3.5T GVWR (ngā waka pāhihi, ngā waka māmā, ngā taraka māmā) ā, kua tawhito kē i roto i ngā tono taraka hou nā runga i ngā ture haumaru. (2) Te rango matua porowhita-rua (porowhita-rua) — e rua ngā piston i roto i te raupapa me ngā porowhita waipēhi motuhake e rua (he wehewehenga whakarara te nuinga: mua-maui + muri-matau i te porowhita 1, mua-matau + muri-maui i te porowhita 2). Ki te kore e pai tetahi porowhita, ka whakarato tonu te porowhita kē i te 50-60% o te parai i runga i ngā wira e toe ana. E hiahiatia ana ngā rango matua porowhita-rua e te ECE R13-H §5.2.1 mō ngā waka katoa i runga ake i te 3.5T GVWR (N2, N3, M2, M3 ngā kāwai) me ngā waka katoa he parai waipēhi. (3) Mō ngā tono taraka OEM i runga ake i te 3.5T GVWR, me whakamahi ngā rango matua ara iahiko-rua. Ko te whirihoranga wehewehe whakarara te mea tino noa, engari ko ētahi OEM e whakamahi ana i te wehewehe mua-muri (ara iahiko mua + ara iahiko muri) e whakarato ana i te 70-80% o te aukati i ngā wira o mua mēnā ka rahua te ara iahiko o muri, i te ritenga kē rānei.
Q3: Ka taea e au te whakamahi i tētahi rango matua nui ake hei whakanui ake i te kaha aukati?
Kāo, kāore e taea te whakamahi noa i tētahi rango matua nui ake hei whiwhi i te kaha pēhi nui ake nā te mea he pūnaha waipēhi kati te pūnaha pēhi me te taurite pēhanga. Ko te whanaungatanga ko: Pēhanga = Kaha Pahi / (Hora Pohi × Ōwehenga Pahi × Ōwehenga Whakakaha). Me nui ake te kaha pahi o tētahi rango matua nui ake hei whakaputa i te pēhanga raina ōrite nā te mea ka tohatohahia te kaha pahi ōrite ki runga i tētahi rohe piston nui ake. Ina koa, mā te whakarea i te diameter o te pohi ka whakawhā te horahanga piston, ko te tikanga me whakawhā te kaha pahi kia puta ai te pēhanga ōrite. Hei tauira, ko te neke mai i tētahi pohi 7/8 inihi (0.60 inihi² te horahanga) ki tētahi pohi 1-inihi (0.79 inihi² te horahanga) me 31% te kaha pahi atu hei whakaputa i te pēhanga raina ōrite. Ko te pānga mahi o tētahi pohi nui ake ko: (1) te pēhanga raina iti ake mō te kaha pahi ōrite, (2) te nekenga wai pēhi atu mō ia whiu pahi (ko te tikanga he roa ake te whiu pahi mō te nekehanga piston caliper ōrite), (3) te ngawari ake pea o te ahua o te pahi. Ko ngā pānga e 3 kāore e hiahiatia ana i roto i ngā tono taraka e tumanako ana ngā taraiwa ki te ahua pahi pakari me te urupare tere. Ko te huarahi tika ko te whakarahi i te poka ki te GVWR e ai ki te SAE J1601, kaua e rahi rawa.
Q4: He aha te wai parai me whakamahi e au me taku puoto matua?
Ko te whakatakotoranga wai parai mō te rango matua e whakawhirinaki ana ki te rauemi hiri me te awhe pāmahana whakahaere. Ko ngā whakatakotoranga wai parai e 3 e pā ana ki te SAE J1703 / FMVSS 116 / ISO 4925 ko: (1) DOT 3 (e ahu mai ana i te glycol-ether) — te iti rawa o te kohua maroke 205°C, te iti rawa o te kohua mākū 140°C; hototahi ki ngā hiri EPDM me te rapa taiao; he pai mō ngā waka arumoni māmā me te mahi parai ngawari, (2) DOT 4 (e ahu mai ana i te glycol-ether-borate) — te iti rawa o te kohua maroke 230°C, te iti rawa o te kohua mākū 155°C; hototahi ki ngā hiri EPDM; he pai mō ngā waka arumoni taumaha me te mahi parai teitei tae atu ki ngā taraka neke atu i te 12T GVWR, (3) DOT 5.1 (e ahu mai ana i te glycol-ether-borate) — te iti rawa o te kohua maroke 260°C, te iti rawa o te kohua mākū 180°C; hototahi ki ngā hiri EPDM; he pai mō ngā tono mahi-teitei me te mahi-nui tae atu ki ngā taraka reihi me ngā waka hōia. Kāore te DOT 5 (he mea hanga ki te silicone) e hototahi ki ngā wai he mea hanga ki te glycol, ā, kaua e whakaranua. Mō ngā puoto matua o Shaoxing Fangjie, ko te rauemi hiri paerewa ko te EPDM e hototahi ana ki te DOT 3, DOT 4, me te DOT 5.1. Ko te whakakī wheketere mō te tuku OEM ko te DOT 4 mō ngā tono waka arumoni taumaha.
Q5: Me pēhea te whakatau i te raru o te pēra pēra ngohengohe i roto i te taraka?
Ka puta pea te pēra pēra ngohengohe i roto i te taraka nā7 ngā take, kua whakarārangihia mā te auau: (1) Te hau i roto i te pūnaha parai (te mea tino noa) — te whakaheke toto i te pūnaha parai e ai ki te tikanga OEM, ka tīmata i te wira i tawhiti rawa atu i te puoto matua, ka anga atu ki te mea tata rawa, (2) Te rahunga o te hiri o roto o te puoto matua — kua pakaru, kua tawhito rānei te hiri kapu tuatahi, tuarua rānei, ka taea ai e te wai te karo i te piston; whakakapia te puoto matua, (3) Te turuturu o te wai parai — tirohia ngā raina parai katoa, ngā calipers, ngā puoto wira, me te tinana puoto matua mō te turuturu o te wai; whakatikahia, whakakapia rānei mēnā e tika ana, (4) Te whānui o te ngongo parai — kua heke te kounga o roto o ngā ngongo parai rapa, ā, ka whānui i raro i te pēhanga, ka puta he āhua ngohengohe o te pētera; whakakapia ngā ngongo parai (ia 4-6 tau te tikanga, 200,000-300,000 km rānei), (5) Te rahunga o te booster — kāore te booster korehau e whakarato i te booster tika, me nui ake te kaha o te pētera hei whakaputa i te pēhanga kotahi; tirohia te raina korehau booster, te takirere tirotiro, me te diaphragm booster; whakakapia te booster mēnā e tika ana, (6) Te rahunga o te hiri piston caliper — kua tawhito te hiri piston caliper, ka taea ai e te wai te karo; hanga anō, whakakapi rānei i te caliper, (7) He hē te poka o te rango matua — he nui rawa te poka mō te GVWR, ka puta he āhua ngohengohe o te pēhanga o te pēhanga i te raina iti; manatokohia te diameter poka e ai ki ngā aratohu SAE J1601. Me tātari ngā take e 7 i te raupapa kua whakarārangihia, me te whakatika i te mea tino noa me te iti rawa o te utu (te toto o te hau) i te tuatahi.
Q6: He aha te wā whakakapinga o te rango matua mō te taraka arumoni?
Ko te wā whakakapinga o te rango matua mō te taraka arumoni he 5-8 tau, 400,000-600,000 km rānei, ko tēhea te mea tuatahi, i raro i ngā āhuatanga mahi noa. E toru ngā āhuatanga e whakatau ana i te wā whakakapinga: (1) Te pakaru o te hiri o roto — ka pakaru haere te hiri kapu tuatahi me te hiri kapu tuarua i ia paninga o te parai; ko te roanga o te ora o te rauemi hiri (te tikanga he EPDM) he tata ki te2-3 miriona huringa parai, e rite ana ki te 5-8 tau o te mahi taraka arumoni noa, (2) Te poke o te wai parai — i roto i te wā, ka mimiti te wai parai i te makuku mai i te hau (he hygroscopic ngā wai DOT 3/4/5.1), e whakaiti ana i te pāmahana kohua me te whakateretere i te waikura o roto; me horoi te wai parai me te whakakapi i ia 2 tau ahakoa te āhua o te puoto matua, (3) Te kakahu o te pūaha puoto — ka pakaru haere te pūaha konumohe i te nekehanga o te piston, inā koa mēnā kua poke te wai parai, mēnā rānei ka pakaru ngā hiri; ko te kakahu o te pūaha i runga ake i te 0.05 mm (0.002 inihi) me whakakapi te puaha matua. Ka hangaia e Shaoxing Fangjie Auto Accessory Co., Ltd. ngā puoto matua me te pūaha konumohe whakapakeke (maimoatanga mata anodized) me ngā hiri EPDM kua whakatauria mō2-3 miriona huringa parai. Ka tūtohu mātou kia whakakapia ā-tau 5 / 400,000 kiromita mō ngā taraka e mahi ana i ngā āhuatanga mahi kino (te auau o te aukati tere, te whenua maunga, te āhuarangi wera). Mō ngā taraka mahi māmā i ngā āhuatanga ngawari, ka taea te roa te wā whakakapinga ki te 8 tau / 600,000 kiromita.
