TL;DR —Pono nā mea kūʻai aku o ka ʻauwaʻa e ʻimi ana i nā cylinders master clutch a me nā cylinders slave no nā kalaka kaumaha a me nā trailer e hoʻomaopopo he hui pū ʻia kēia mau ʻāpana ʻelua akā ʻokoʻa ka mechanical - hoʻopuka ka cylinder master i ke kaomi hydraulic mai ka hoʻokomo pedal; hoʻololi ka cylinder slave i kēlā kaomi i ka ikaika mechanical e wehe i ka clutch. ʻO nā palena ʻekolu i mea nui loa i ke kūʻai nui ʻana: ka hoʻohālikelike ʻana o ka bore-stroke ma waena o ka master a me ke slave (ʻo ka mismatch o 2 mm i ke anawaena bore e hoʻololi i ka hoʻoikaika pedal clutch ma 15-20%), ka hoʻohālikelike ʻana o ka lōʻihi o ka stroke pushrod me ke kumu hoʻohālike kalaka kikoʻī (IVECO, MAN, DAF, a i ʻole Volvo e hoʻohana i nā ʻano stroke like ʻole mai 25 mm a 42 mm), a me ka hōʻoia helu hoʻololi OEM (hoʻokahi cylinder master clutch IVECO e lawe a hiki i 7 mau helu cross-reference ma waena o nā hōʻailona OE a me aftermarket). Uhi kēia ʻatikala i kaʻu mea i aʻo ai mai ka hoʻolako ʻana i nā ʻāpana hydraulic clutch i nā mea kūʻai aku ʻauwaʻa ʻEulopa a me Hikina Hema.

ʻO ka maʻamau, hoʻololi nā luna mālama kaʻa kalaka ma ʻEulopa a me ka Hikina Hema ʻAsia i nā ʻāpana hydraulic clutch i nā ʻāpana - 50 a 200 mau ʻāpana no kēlā me kēia kauoha - e mālama i kahi pae waihona liʻiliʻi loa ma waena o kahi kaʻa he 20 a 100 mau kalaka. ʻO nā ʻāpana hydraulic clutch i kauoha pinepine ʻia no nā kalaka kaumaha (IVECO, MAN, DAF, Volvo, Scania, Mercedes-Benz) ʻo ia ka clutch master cylinder a me ka clutch slave cylinder. Ke hoʻolako nei au i kēia mau ʻāpana ma o ka mahele hoʻokuʻu aku o Fangjie mai ka makahiki 2003, a ʻo ka hewa maʻamau aʻu e ʻike ai mai nā mea kūʻai aku kaʻa ka kauoha ʻana i nā master cylinders a me nā slave cylinders me he mea lā he mea hoʻololi lākou - ʻaʻole lākou. ʻO kahi master cylinder a me kahi slave cylinder mai nā mea hana like ʻole a i ʻole me nā lakio bore-stroke kūpono ʻole e hana i kahi manaʻo pedal i hiki ʻole ke ʻae ʻia: kaumaha loa (ʻoi aku ke kaomi pedal ma mua o 35 kg no ka wehe ʻana o ka clutch) a i ʻole māmā loa akā me ka huakaʻi clutch piha ʻole (ʻaʻole wehe piha ka clutch, e hana ana i ka wili ʻana o nā gear ma kēlā me kēia neʻe).

Uhi kēia ʻatikala i nā ʻokoʻa e pono ai ka mea kūʻai aku i ka ʻauwaʻa e hōʻoia ma mua o ke kau ʻana i kahi kauoha nui. No ka laulā piha o nā cylinders master clutch a mākou e hana ai, e ʻike i kaʻaoʻao huahana cylinder master clutchNo ke kumu hoʻohālike IVECO kikoʻī ʻo ia kekahi o kā mākou mau kuhikuhi i noi nui ʻia, e ʻike i kaʻAoʻao huahana cylinder master clutch IVECO.

ʻOkoʻa Hana - Hoʻokumu ke Kumu i ke Kaomi, Hoʻololi ke Kauā iā ia

ʻO ka silindro haku clutch a me ka silindro kauā clutch he ʻelua mau ʻāpana hydraulic kaʻawale e lawelawe ana i nā hana like ʻole. Hoʻopaʻa ʻia ka silindro haku ma ka ʻaoʻao ʻenekini o ka pā ahi, i pili pono i ka lever pedal clutch. Ke kaomi ka mea hoʻokele i ka pedal clutch, hoʻokuke ka pushrod i loko o ka silindro haku i ka piston mua i mua, e koi ana i ka wai hydraulic (wai brake a i ʻole ka ʻaila mineral, ma muli o ka kikoʻī o ka mea hana kalaka) ma o ka paipu clutch i ka silindro kauā. Hoʻopaʻa ʻia ka silindro kauā ma ka hale bele gearbox, a i ka wā e komo ai ke kaomi hydraulic i loko o ka silindro kauā, hoʻokuke ia i ka pushrod silindro kauā e kūʻē i ka ʻōpuʻu hoʻokuʻu clutch, kahi e wehe ai i ka disc clutch.

ʻOi aku ka nui o ke anawaena o ka lua o ka cylinder master ma mua o ke anawaena o ka lua o ka cylinder slave i loko o kahi pālua i hoʻohālikelike pono ʻia - ʻo ka lua o ka cylinder master he 20-26 mm maʻamau, a ʻo ka lua o ka cylinder slave he 16-22 mm maʻamau. ʻO ka lakio lua (lua o ka ÷ lua o ka slave) e hoʻoholo i ka leverage hydraulic. No kahi kalaka DAF CF a i ʻole XF series, ʻo ka lakio lua kūpono he 1.25:1 a i 1.35:1. No kahi IVECO Stralis a i ʻole S-Way, ʻo ka lakio kūpono he 1.15:1 a i 1.25:1. ʻO kahi mea kūʻai ʻauwaʻa e kauoha ana i kahi cylinder master me kahi lua 24 mm a me kahi cylinder slave me kahi lua 18 mm (lakio 1.33:1) no kahi IVECO S-Way e koi ana i ka lakio 1.20:1 e hana i kahi pedal e manaʻo ʻia he 18% kaumaha ma mua o ka kikoʻī OE - e hoʻopiʻi nā mea hoʻokele ʻauwaʻa i ka luhi o nā wāwae ma nā ala lōʻihi.

Hoʻohālikelike Bore-Stroke - ʻO ka Ana Koʻikoʻi Hoʻokahi

Pono e hōʻoia ʻia ka hui pū ʻana o ka bore-stroke no ka master a me ka slave cylinder ma mua o ke kau ʻana i kahi kauoha nui. ʻO ka master cylinder stroke ka mamao e hele ai ka piston i loko o ka master cylinder bore ke kaomi piha ʻia ka pedal clutch - ʻo kēia maʻamau he 25-42 mm no nā noi kalaka kaumaha. ʻO ka slave cylinder stroke ka mamao e hele ai ka piston slave e paʻi i ka clutch release fork - maʻamau he 12-20 mm. ʻO ka neʻe ʻana o ka wai o ka master cylinder (bore area × stroke) pono e like a ʻoi iki paha i ka koi wai o ka slave cylinder.

Ua hana au i kahi kauoha pūʻulu mai kahi mea hoʻolaha ʻauwaʻa ʻEulopa nāna i kauoha i 200 mau cylinders haku clutch me ka hahau 22 mm × 30 mm, i hui pū ʻia me 200 mau cylinders kauā me ka hahau 18 mm × 16 mm. ʻO ka neʻe ʻana o ka cylinder haku he π × (11 mm)² × 30 mm = 11,404 mm³. ʻO ke koi cylinder kauā he π × (9 mm)² × 16 mm = 4,072 mm³. ʻO ka neʻe ʻana o ka cylinder haku he 2.8 mau manawa o ke koi cylinder kauā - aia kēia lakio i loko o ka laulā i ʻae ʻia (2.5:1 a 3.5:1) no ke kumu hoʻohālike kalaka, a ua ʻae ʻia ka pūʻulu ma hope o ka hoʻāʻo kūpono ma kahi kaʻa laʻana. ʻO ke kānāwai aʻu e hoʻopili ai: pono ka neʻe ʻana o ka cylinder haku he 2.8–3.2 mau manawa o ka neʻe ʻana o ka cylinder kauā no kahi pālua i hoʻohālikelike pono ʻia ma kahi ʻōnaehana clutch kalaka kaumaha me kahi bearing hoʻokuʻu hydraulic, a me 2.0–2.5 mau manawa no kahi ʻōnaehana me kahi ʻōpuʻu hoʻokuʻu clutch mechanical. ʻO nā mea hana hydraulic clutch OEM ʻEulopa e like meFTE Automotivee hoʻohana i nā helu like o ka lakio bore-stroke i kā lākou mau kikoʻī ʻenekinia huahana.

ʻO ke ʻano o ka Pushrod a me ke kau ʻana — ʻAʻole like nā Cylinders Master Clutch āpau

ʻOkoʻa ke ʻano o ka hoʻonohonoho ʻana o ka clutch master cylinder pushrod ma waena o nā mea hana kalaka. Hoʻohana ka IVECO master cylinder i kahi mea hoʻohui pushrod ʻano U me ke anawaena pine 10 mm a me ka lōʻihi pushrod 45 mm mai ke kikowaena pine a i ka piston. Hoʻohana ka DAF master cylinder i kahi mea hoʻohui fork ʻano Y me kahi pine 12 mm a me kahi pushrod 55 mm. Hoʻohana ka Volvo master cylinder i kahi pushrod pololei me kahi nati hoʻoponopono M8 i wili ʻia. ʻO ke ʻano o kēia mau ʻokoʻa ʻaʻole hiki ke hoʻololi ʻia kahi master cylinder i hoʻolālā ʻia no kahi DAF CF me kahi ʻāpana IVECO Stralis, ʻoiai inā like ke anawaena bore a me ka hahau. Pono ka mea kūʻai aku i ka ʻauwaʻa e hōʻoia i ke ʻano o ka mea hoʻohui pushrod, ke anawaena pine, a me ka lōʻihi holoʻokoʻa mai ka maka flange hoʻopaʻa a i ke kikowaena pine pushrod, i ana ʻia ma millimeters.

He ʻokoʻa nō hoʻi ke ʻano o ke kau ʻana o ka bolt: hoʻohana ʻo IVECO i ʻelua mau bolts M8 ma kahi mamao kikowaena 52 mm; hoʻohana ʻo DAF i ʻelua mau bolts M10 ma kahi mamao kikowaena 60 mm; hoʻohana ʻo MAN i ʻekolu mau bolts M8 ma kahi ʻano triangle equilateral 56 mm. ʻAʻole hiki ke hoʻokomo ʻia kahi cylinder haku me kahi ʻano bolt kau ʻana he 4 mm ka mamao mai nā lua bracket o ke kalaka me ka ʻole o ka ʻeli ʻana i nā lua hou - ʻaʻole ia he mea ʻae ʻia no kahi hale hana mālama ʻauwaʻa e pono ai ke kalaka e hoʻihoʻi i ka lawelawe i loko o 2 mau hola.

Hoʻohālikelike ʻAno Wai — Wai Paleki vs. ʻAila Minerala

Hoʻohana ka ʻōnaehana hydraulic clutch i loko o nā kalaka kaumaha i ka wai haki maʻamau (DOT 3, DOT 4, a i ʻole DOT 5.1) a i ʻole ka ʻaila mineral (ʻo Shell Tellus maʻamau a i ʻole like, i kuhikuhi ʻia e ka mea hana kalaka). He ʻokoʻa nā mea sila i loko o ka silindro haku a me ka silindro kauā no kēlā me kēia ʻano wai. Hoʻohana nā ʻōnaehana wai haki i nā sila laholio EPDM; hoʻohana nā ʻōnaehana ʻaila mineral i nā sila NBR (nitrile rubber). ʻO ka mea kūʻai ʻauwaʻa e hoʻokomo i kahi silindro haku me nā sila EPDM i loko o kahi ʻōnaehana clutch e hoʻohana ana i ka ʻaila mineral e ʻike i nā sila e pehu a hāʻule i loko o 200 mau hola, e hoʻoulu ai i ka pedal clutch e hele i ka papahele me ke kaomi ʻole o ka hydraulic. Hōʻike pinepine ʻia ke ʻano wai ma ka pāpale waihona silindro haku - DOT 3/4/5.1 no ka wai haki, a i ʻole kahi hōʻailona ʻaila mineral. Pono ka silindro haku pani e kuhikuhi i ka mea sila kūpono. Ma Fangjie, loaʻa kēlā me kēia kumu hoʻohālike silindro haku clutch i nā ʻano sila EPDM a me NBR, a pono ka mea kūʻai ʻauwaʻa e kuhikuhi i ka mea sila i ke kauoha ʻana.
