ʻōnaehana braking. Pehea e mālama ai?

ʻO ka ʻōnaehana braking ʻaʻole kānalua kekahi o nā mea koʻikoʻi o ke kaʻa, pili pono i ka maikaʻi a me ka palekana o ke kaʻa.

Ma ka ʻatikala o kēia lā, e hoʻāʻo mākou e hōʻike i nā pilikia maʻamau, nā hewa a me nā kumu kumu no ka hana kūpono o ka ʻōnaehana brake. Ma keʻano kūikawā, e kamaʻilio mākou e pili ana i nā pad brake a me nā disc.

ʻO ka mua, he manaʻo liʻiliʻi - pono ka ikaika braking e wāwahi i kahi kaʻa. No kona hoʻokumu ʻana, pono ia e hana i kahi torque braking ma ka huila. He mea ia o ka ikaika i hoohanaia a me ka lever e hana ai. ʻO ka ʻōnaehana braking hydraulic ke kuleana no ka hoʻohana ʻana i ka ikaika ma o ka hoʻoili ʻana iā ia i nā discs ma o nā pale pale. He lever ka diski, no laila, ʻoi aku ka nui o ke anawaena disc, ʻoi aku ka nui o ka torque braking i hana ʻia.

ʻO ke kaʻina hana kaʻa kaʻa ponoʻī e hoʻololi i ka ikehu kinetic o kahi kaʻa e neʻe nei i ka ikehu wela i hana ʻia e ka friction o nā pale pale ma nā disc. He mea nui ka nui o ka ikehu wela. Ma kahi kaʻa kīwila, hiki iā ʻoe ke hoʻomaʻamaʻa maʻalahi i ka ʻōnaehana kaomi-block-disk i 350 degere Celsius! ʻO ia ke kumu i hana pinepine ʻia ai nā disc me ka hao hina hina. Hōʻike ʻia kēia mea e ka conductivity thermal maikaʻi loa a me ka maʻalahi o ka hana ʻana i nā castings paʻakikī. ʻOi aku ka nui o ke anawaena disc, ʻoi aku ka nui o ka wela e hiki ke hoʻopaʻa a ʻoi aku ka maikaʻi o ke kaʻina hana braking. Eia naʻe, ʻo ka piʻi ʻana o ke anawaena o ka disc e hoʻonui ai i kona nuipa, a ʻo ia ka mea i kapa ʻia ʻo "Unsprung mass", ʻo ia hoʻi, ka mea i uhi ʻole ʻia e ka hana hoʻomaha. ʻO ka hōʻoluʻolu o ka neʻe ʻana a me ka lōʻihi o nā mea puna-damping ponoʻī iā lākou iho e pili pono i kēia.

E nānā pū hoʻi: ka wai kaʻa. Nā hopena hoʻāʻo weliweli

No laila, hoʻāʻo nā mea hana e ʻimi i kahi kuʻikahi ma waena o ka ikaika i kaomi ʻia e ka piston ma ka pahu pahu a me ka nui o ka pahu pahu a me ka disc. Eia kekahi, ke ho'āʻo nei nā mea hana i nā ʻano like ʻole e hoʻopau i ka wela e hōʻiliʻili ai ma ka dial. Hoʻokaʻawale ʻia ka ʻili o ka friction (ma) a i ʻole ʻia ma waena o nā wahi hana o nā disks (ka mea i kapa ʻia ʻo ventilated disks). ʻO nā mea a pau i ka inoa o ka hoʻopau wela ʻoi aku ka maikaʻi.

I ka hihia o nā diski i hoʻolālā ʻia no ka haʻuki a i ʻole ka hoʻohana ikaika loa, ʻoki pinepine a ʻoki paha nā mea hana i ka papa hana i kahi hohonu i koho mua ʻia e hoʻomaʻamaʻa i ka wehe ʻana o nā kinoea i hana ʻia e ka friction o nā ʻāpana ʻōnaehana. Hoʻomaʻemaʻe hoʻi nā notches i ka lepo e hōʻiliʻili ana ma luna o nā pads a ʻoki i ka ʻili o nā pads i maʻemaʻe mau ka pad a pili pono i ka disc. ʻO ka hemahema o kēia hoʻonā ʻana ʻo ia ka wikiwiki o ka ʻaʻahu ʻana o nā pale pale.

E pili ana i nā pad brake, ʻokoʻa mākou i ʻehā mau ʻano nui ma muli o ka mea i hana ʻia ai kā lākou ʻāpana friction:

semi-metal - ka mea ʻoi loa, ʻoi aku ka leo. Hoʻololi maikaʻi lākou i ka wela, kahi e hoʻomaikaʻi ai i ka hana braking. Hana ʻia ka pale ʻana me ka hulu kila, ka uwea, ke keleawe, ka graphite, etc.

asbestos (LLW) - aniani, pulupulu, kalapona i paa i ka resin. He mālie lākou akā ʻoi aku ka lōʻihi ma mua o ko lākou mau semi-metal. He lepo loa nā diski.

metala haʻahaʻa (LLW) - ka uhi ʻana o nā pūhui organik me kahi hui liʻiliʻi o nā metala (ke keleawe a i ʻole ke kila). He maikaʻi loa lākou akā leo nui.

ceramic - ʻoi aku ka nui o ke kumukūʻai i hoʻohālikelike ʻia i nā ʻano poloka i luna. Hana ʻia lākou mai nā fiber seramika, nā mea hoʻopihapiha a me nā mea hoʻopili. I kekahi mau hihia, hiki ke loaʻa i nā metala liʻiliʻi. Ua ʻoi aku ka mālie a me ka maʻemaʻe a loaʻa iā lākou ka pōmaikaʻi hou o ka hōʻino ʻole ʻana i nā disc brake.

He aha nā pilikia e hiki iā mākou ke kū i ka wā e hana ai i ka ʻōnaehana braking?

E hoʻomaka kākou me ka ikehu wela i ʻōlelo ʻia aʻe nei. Inā mākou e hoʻomaʻamaʻa i nā disks i ka 300-350 degere Celsius i ʻōlelo ʻia ma mua (ʻo kekahi mau dynamic braking mai 60 km / h a hiki i kahi hoʻomaha holoʻokoʻa ua lawa), a laila holo i loko o kahi puddle hohonu, me kahi kiʻekiʻe kiʻekiʻe e ʻike mākou i kahi. ʻo ka puʻupuʻu ma ka pedal brake. me kēlā me kēia braking hope. ʻO ka ninini ʻana i nā diski me ka wai e hoʻomaʻalili wikiwiki ʻole ʻia, e alakaʻi ana i ko lākou piko. Paʻi ʻia kahi diski haki i ka pā kaʻa, e hoʻoulu ai i nā manaʻo maikaʻi ʻole ma ka pedal brake a me ka haʻalulu o ka huila. Aia kekahi "ki" o ke kaʻa i ka wā e paʻa ai.

No laila e pale aku i ke kaʻa ʻana i loko o nā puddles hohonu - ʻo kā mākou pahu pahu a me nā mea ʻē aʻe e uku no lākou iho no ka hoʻohana lōʻihi.

Hiki iā mākou ke ho'āʻo e mālama i kahi disc brake warped ma ka ʻōwili ʻana. ʻO ke kumukūʻai o ia lawelawe ma kahi o PLN 150 i kēlā me kēia axle. ʻO ia kaʻina hana kūpono i ka hihia o ka curvature o nā diski hou. Ma hope o ka ʻōwili ʻana, pono e loaʻa i ka disc ka mānoanoa hana haʻahaʻa i kuhikuhi ʻia e ka mea hana. A i ʻole, pono ʻoe e kūʻai i kahi pūʻulu o nā ʻili maka hou i kēlā me kēia axle.

E nānā pū: Ke hoʻāʻo nei i ka Mazda 6

No ke aha e mālama pono ʻia ai ka mānoanoa hana haʻahaʻa i ʻōlelo ʻia?

ʻAʻole lawa ka wela wela o ka diski ʻeleʻele a lahilahi loa. Hoʻopau koke ka ʻōnaehana a i ka wā e hoʻopaʻa ʻia ai ka pilikia, nalowale koke ʻoe i ka mana braking.

Hiki nō hoʻi i ka pohā ka diski lahilahi loa.

ʻO ka haʻihaʻi radial o ka disc e hopena i ka ʻōhumu e piʻi aʻe i ke alapine i ka piʻi ʻana o ka wikiwiki o ka rotational. Eia kekahi, i ka wā o ka hoʻopaʻa paʻa, hiki ke kū mai ka pulsation o ka pedal brake.

Hiki i ka diski ʻeha ke kumu i ka haʻihaʻi pōʻai. He pōʻino loa kēia ʻano māwae. ʻO ka hopena, hāʻule paha ka ʻili hana o ka diski mai ka huila!

ʻO kahi pilikia ʻē aʻe e hiki ke hoʻopilikia i nā disc brake ʻo ka ʻino o ka ʻili. ʻAʻole kēia he mea maʻamau, ʻoi aku hoʻi inā haʻahaʻa loa ka ea a i ʻole mākou e holo ma nā alanui i kāpīpī ʻia me ka paʻakai alanui. Wehe ʻia ka uhi ʻōpala ma hope o ka hoʻopaʻa mua ʻana, akā pono mākou e hoʻomanaʻo a hiki i ka hemo ʻana o ka ʻōpala, ʻike ʻole ʻia kā mākou ʻōnaehana braking. Hiki ke ʻike ʻia ka ʻino ma nā diski ma ke ʻano o ke kani ʻana o ke kaʻa i ka wā e paʻa ai no ka manawa mua ma hope o ke kū lōʻihi. ʻO kahi leo hoʻomākeʻaka ʻano nui e hōʻike ana e ʻohi ana nā pads i ka ʻōpala mai nā disc.

ʻO kahi pilikia ʻē aʻe me ka ʻōnaehana brake he squeak maikaʻi ʻole. Hōʻike maʻamau kēia i ka ʻaʻahu nui o nā mea friction o ka ʻōnaehana. Hoʻomaka nā ʻāpana metala o ka pā kaʻa e ʻānai i ka diski, e kani ana, e hoʻoulu ai i ka leo nui, ʻinoʻino a i ʻole ke kani ʻana. I kēia hihia, ʻaʻohe koho ʻē aʻe akā e hoʻololi i nā mea i hoʻohana ʻia. Pono e hoʻokō koke ʻia ka hoʻololi ʻana, no ka mea, ʻo ka friction o nā mea metala ma ka diski i ʻōlelo ʻia ma luna nei hiki ke alakaʻi i ka pōʻino hiki ʻole i ka disc. I ka hopena o ka wikiwiki, hiki ke hoʻopau ʻia ka hoʻoponopono ʻana me ka hoʻololi ʻana o nā pad iā lākou iho. Hiki nō hoʻi ke kumu o ke kani ʻana o ka pahu ma muli o nā ʻili lepo ma luna o nā disks a me nā pā. I kēia hihia, pono e kōkua ka hoʻomaʻemaʻe ʻana i ka ʻōnaehana me ka mea i kapa ʻia ʻo Brake Cleaner, kahi e hoʻomaʻemaʻe a hoʻomaʻemaʻe i nā discs a me nā pad brake.

He aha nā pilikia e hiki ke loaʻa i nā pad brake?

ʻO ka mea mua, hiki i nā pads ke overheat. ʻO ka ʻoi aku ka lahilahi, ʻoi aku ka paʻa o ka gasket, ʻoi aku ka haʻahaʻa o kona kūpaʻa i ka wela kiʻekiʻe. I ka hopena o ka wela nui, ʻā ka mea nāna e hoʻopaʻa i ka mea friction ma waho o ka pā. ʻOi aku ka liʻiliʻi o ke kuʻekuʻe ʻana o ka pad i ka wā e hoʻopili ai me ka disc, e hōʻemi ana i ka ikaika braking a me ka lōʻihi. Eia kekahi, hiki iā ia ke hana i nā squeals hoʻonāukiuki.

ʻO ka mea hope loa, pono mākou e haʻi i nā hewa maʻamau i hana ʻia e nā mea hoʻokele, e hōʻemi nui i ka lōʻihi o ka ʻōnaehana braking. ʻO ke kumu maʻamau, ʻo ka ʻenehana hoʻokele maikaʻi ʻole. ʻO ka hoʻopaʻa lōʻihi ma ka piʻi ʻana, lōʻihi ka iho ʻana a me ka mālama mau ʻana i kou wāwae ma ka pedal brake e alakaʻi i ka wela nui o ka ʻōnaehana. Ke kaʻa ʻana ma ka ʻāina mauna, e hoʻomanaʻo i ka hoʻohana ʻana i ka ʻenekini braking a, inā hiki, e hoʻohana i ke ʻano o ke kaʻa pōkole ʻoi aku ka paʻakikī a me ka hoʻokuʻu manawaleʻa o ka pedal brake e hiki ai i ka ʻōnaehana ke anuanu.

E like me nā manawa a pau, pono e haʻi i ka pale ʻana. I kēlā me kēia nānā ʻana, koi mākou i kahi mechanic e nānā i ka ʻōnaehana brake! ʻO kēia hana maʻalahi, hoʻohana mau ʻia e loaʻa ka hopena maikaʻi i ko mākou palekana, ka hōʻoluʻolu hoʻokele a me ke kūlana o kā mākou ʻeke.
