ʻO ke kāʻei ʻana i nā pad brake, discs a me nā pahu (nā kumu o ka hoʻohana wikiwiki ʻana i nā ʻāpana o ka ʻōnaehana brake)

E hoʻohana i nā ʻāpana i loko o ka ʻōnaehana kaʻa o ke kaʻa, a ʻo ia nā disc, pahu a me nā pads ʻaʻole hiki ke hoʻololi ʻia ma muli o kā lākou kumu waiwai ʻole. Aia nā mea a pau i ke kūlana kaʻa, nā maʻamau o ka mea hoʻokele a me ka maikaʻi o nā mea. No laila, he mea nui e loiloi i ke kūlana o nā ʻāpana me ka manawa paʻa i mea e hoʻoponopono ai i kahi loli koʻikoʻi i nā ana mana i ka manawa.

ʻO ke kumu o ka hana o ka ʻōnaehana braking i ke kaʻa

ʻO ka loina maʻamau o nā brakes ka hoʻonohonoho ʻana o ka friction ma waena o nā ʻāpana i hoʻopili paʻa ʻia i nā mea hoʻokuʻu a me nā ʻāpana e kaʻa me nā huila.

ʻO ka loaʻa ʻana o kēia ikaika e hoʻopau i ka ikehu o kahi kaʻa neʻe, hoʻemi i ka wikiwiki.

Paʻa diski

ʻO ke ʻano o ka disc-type brake me kahi caliper i hoʻopili ʻia i nā lima hoʻomaha ma o nā ʻāpana ʻē aʻe, e hoʻololi like me ka huila disc a me nā pad brake.

Me ka piʻi ʻana o ke kaomi i loko o ka hydraulic brake cylinders i hana i ka caliper, hoʻomaka kā lākou pistons e neʻe, e hoʻololi i nā pads e uhi ana i ka disc ma nā ʻaoʻao ʻelua. ʻOi aku ka liʻiliʻi o ka ʻāpana pad ma mua o ka ʻāpana ʻaoʻao o ka disc, ʻo ia hoʻi, hopu lākou i kahi ʻāpana liʻiliʻi wale nō.

Hiki ke ʻokoʻa ka helu o nā cylinders i loko o ka caliper, ma muli o ka pono o ka brake i koi ʻia a me nā kumu ʻē aʻe, akā aia mau ʻelua mau pad e neʻe ana kekahi i kekahi.

Hāʻawi ʻia kā lākou preload e nā cylinders counter-operating, a i ʻole e ka mea i kapa ʻia ʻo floating type bracket, inā ʻaʻohe pono o ka cylinder lua.

ʻO ke kumumanaʻo o ka hana ʻana o kahi caliper me kahi ʻano lana:

• 1 — pale.
• 2 - alakaʻi.
• 3 - apo apo.
• 4 - caliper me ka cylinder.
• 5 - piston.
• 6 - puʻupuʻu.
• 7 - nā pā.
• 8 - disc brake.
• 9 - ka wai kaʻa.
• 10 - kūpono.

Caliper me ka hoʻolālā paʻa:

• 2 - kau ʻana i nā bolts.
• 4 - caliper me nā cylinders.
• 5 - pistons.
• 6 - hoʻopaʻa i nā cuffs.
• 7 - nā pā.
• 8 - disc brake.
• 9 - ka wai kaʻa.
• 10 - kūpono.

He nui nā pono o ka disc brake i hōʻoia i kona hoʻohana ʻana i ka hapa nui o nā kaʻa:

1. ʻO ka maikaʻi wela kiʻekiʻe, no ka mea, ʻaneʻane hāmama loa ka disk a loaʻa no ka hoʻoluʻu ʻana e ka ea o waho.
2. ʻO ka maʻalahi a me ka hoʻolālā paʻa.
3. ʻO ka maʻalahi o ka nānā ʻana i ke ʻano o nā ʻili o nā pads a me nā disc.
4. Hiki i ka hoʻohana ʻana i ka ventila hou me ke kōkua o ke ʻano o loko o ka disc a me kāna perforation.
5. ʻO ka haʻahaʻa haʻahaʻa i ka lepo a me ka komo ʻana o ka makū ma muli o nā kūlana maikaʻi no ka hoʻomaʻemaʻe ponoʻī.

ʻO ka mea no nā disks ka mea maʻamau i hoʻolei ʻia i ka hao, nona nā waiwai frictional ʻoluʻolu a me ko lākou kūpaʻa, ʻoi aku ka liʻiliʻi o ke kila, a no nā noi haʻuki, hoʻohana ʻia nā mea i hoʻohui ʻia e hiki ai ke hana i nā wela kiʻekiʻe me ka nalowale o ka ikaika a me ka geometry.

Nā disc brake TRW a me TEXTAR - hoʻohālikelike i nā mea hana kaulana

Aia nā pads i kahi substrate kila, kahi i hoʻopaʻa ʻia ai nā linings friction i hana ʻia i kahi mea i koho ʻia e nā makahiki he nui o ka noiʻi ʻana me ke kāpili kūikawā a me nā spike i hoʻoheheʻe ʻia.

Aia ka paʻakikī ma ka ʻae ʻana ma waena o nā waiwai kū'ē, kiʻekiʻe ka nui o ka friction ma ka hao a me ke kila, ka pale ʻana i ka ʻaʻahu, ka hiki ke pale i nā disc mai ka ʻaʻahu ʻana, ke kūpaʻa wela a me ka haʻahaʻa haʻahaʻa o ka leo kani.

Nā paleki pahu

Hoʻokomo pū lākou i nā pahu pahu i ke ʻano o nā cylinders i pani ʻia ma kekahi ʻaoʻao a me nā pad brake e hana ana ma ko lākou ʻili i loko.

Aia i loko nā pahu hydraulic hana; ke kaomi ʻoe i ka pedal, hoʻokuʻu lākou i nā pad i kahi kaʻawale, kaomi iā lākou i nā pahu. ʻOi aku ka liʻiliʻi o ka ʻāpana pad ma mua o ka ʻili cylindrical i loko.

Ua kaupalena ʻia ka hoʻohana ʻana i ia mau mīkini, ma muli o kekahi mau hemahema kumu:

• nā hemahema hoʻoluʻu, hana nā pads i kahi lua paʻa;
• ʻino ka pale ʻana o nā linings i ka wā e komo ai ka wai i loko o ka pahu;
• nā ana nui a me ke kaumaha o ka hale holoʻokoʻa.

I ka manawa like, loaʻa i nā pahu ko lākou pono ponoʻī, ʻo ke kūʻē ʻana i ka contamination, ke ola lōʻihi o ka lawelawe ʻana a me ka maʻalahi o ka ʻenehana.

No ke aha i pau ai nā pad brake, disc a me nā pahu

ʻO Friction, e hana ana ma ke ʻano he kumu hana nui i ka maikaʻi o nā brakes, loaʻa kahi ʻano kino kino. He kuʻi kēia ma waena o ka liʻiliʻi liʻiliʻi, ka ʻāʻī o ka ʻānai ʻana i nā papa, ʻaʻole e noho mau me ka ʻole o nā hopena no lākou.

A ʻo kēia mau hopena ke kaumaha, ʻoi aku ka kiʻekiʻe o ka coefficient o friction, ʻo ia hoʻi, ʻoi aku ka wikiwiki o ka mīkini. Pono mākou e koho i kahi kuʻikahi ma waena o ka maikaʻi o ka braking a me ka lōʻihi o nā ʻāpana.

Ma muli o nā makahiki he nui o ka ʻike, ua koho ʻia ka lining a me nā mea disc i ke ʻano e hiki ai i ka disc awelika ke ola i ʻekolu a ʻehā paha mau papa. ʻO kēia ka mea maikaʻi loa e pili ana i ka ratio o ke kumukūʻai o kahi diski nui a pipiʻi i ke kumukūʻai o nā pads maʻalahi, i manaʻo ʻia he mau mea hoʻopau.

Nā Paʻi Paʻa a me nā Pad Brake ma hope o 40 km o ka holo kaʻa

Nā kumu o ka ʻaʻahu wikiwiki

Hoʻemi ʻia ke ola lawelawe o nā mea friction brake ma muli o kekahi mau kumu.

1. Ke ʻano holo kaʻa. He mea maʻamau me ka hoʻohana pinepine ʻana i ka pedal, e hele wikiwiki ana ka lole, ʻoi aku ka nui inā ʻaʻohe manawa o nā pahu e hoʻomaha ai.
2. ʻO nā haʻalele i nā waiwai o nā mea. ʻAʻole i nā manawa a pau me nā mea pani o kēia manawa, hoʻokomo ʻia nā disc (drums) a me nā pads e like me ka mea ma ka hale hana. Hiki ke hana ʻia nā diski mai ka hao hoʻolei like ʻole a me ke kalapona, a ua hana ʻia nā pads me ka hoʻohana ʻana i nā ʻenehana like ʻole, me ka hoʻohana ʻana i nā mea kuʻuna me ka ʻole asbestos, ka hoʻokomo ʻana i nā metala a i ʻole nā ​​mea kūlohelohe. ʻO ka hopena, hiki ke hoʻololi pinepine i nā pads a i ʻole disc me ka maikaʻi like i nā hui like ʻole.
3. lepo ma luna o ka hana. Hana ʻia ka lepo a me ke one ma ke ʻano he abrasives, e hoʻolalelale i ka ʻaʻahu.
4. ʻO ka pōʻino disc a me ka hoʻohaʻahaʻa ʻana i nā mea. Hiki iā lākou ke hana ma muli o ka hoʻohana ʻole ʻia o nā kaʻa, a ʻo ia hoʻi, ka wela mau.
5. Nā hana ʻino o ka mea alakaʻi o ka pahu. ʻAʻole e paʻi like nā pads, e hōʻea i ka ʻaʻahu hoʻokahi ʻaoʻao.
6. Nā pilikia pili huilake hana ka huila hope i ka hamo mau ʻana i nā pad ma ka diski.
7. ʻO nā hewa i ka mālamaʻana i nā āpau. Ka mālama ʻole ʻana i ka hoʻoponopono ʻana i ka pahu pahu a i ʻole ka ʻawaʻawa ʻana o nā pistons i nā pahu disc.

E like me kāu e ʻike ai, hiki ke hoʻohana ʻia ka wikiwiki no nā kumu kūlohelohe a mai ka nānā ʻole ʻana o ka mea hoʻokele.

No ke aha e ʻike ʻia ai nā ʻāpana like ʻole

ʻO ka pinepine kēia ma muli o ka corrosion o loko o nā pistons a me nā cylinders i ka hydraulic drive. ʻOi loa i nā mīkini piston multi. Aia pū kekahi ʻawaʻawa i ka mea alakaʻi o ka caliper.

Hoʻopaʻa ʻia ka bracket, no laila e kaomi ikaika ʻia nā pad ma kekahi ʻaoʻao ma mua o kekahi. Pono e hoʻokaʻawale ʻia ka caliper, hoʻomaʻemaʻe ʻia a lubricated, e pale aku i ka momona mai ke kau ʻana ma luna o nā wahi friction. Akā ʻoi aku ka maikaʻi o ka hoʻololi ʻana i nā ʻāpana.

Ke pani nei i ka anther brake caliper Audi A6 C5, Passat B5

He aha ka pilikia o ke komo ʻana o nā ʻāpana o ka ʻōnaehana brake

Ke hiki aku nā ʻāpana i nā ʻāpana koʻikoʻi, hāʻule ka hana braking, ʻaʻole i ʻike mau ʻia ma muli o nā waihona i kūkulu ʻia i loko o ka ʻōnaehana braking. He hoʻopunipuni kēia, hiki ke hāʻule koke nā pahu me nā hopena hiki ʻole ke hoʻoponopono ʻia.

I ka paʻi kiʻekiʻe loa o nā pads, me ka ʻaʻahu ʻae ʻole ʻia, ʻoi aku ka lōʻihi o nā pistons mai nā cylinders, e hāʻule ana i loko o nā wahi i hoʻohana ʻole ʻia. Loaʻa ka nui o ka jamming me ka piʻi ʻana e like me ka avalanche i ka lole a me ka pau ʻole.

Hoʻonui ʻia kēia e ka emi ʻana o ka mānoanoa o ka disk ma lalo o ka palena i ʻae ʻia. Loaʻa i kēlā me kēia kaʻa kona palena liʻiliʻi liʻiliʻi, pono e mālama ʻia i kēlā me kēia mālama i hoʻonohonoho ʻia.

Ke nānā nei i nā pads me ka wehe ʻole ʻana i ka huila

ʻAʻole hiki ke hana i kēia me ka wehe ʻole ʻana i ka huila. Pono ka diski i ka mamao ma waena o nā ʻōlelo e hāʻawi i ka mana ʻike. I kekahi manawa pono ʻoe e hoʻohana i ke aniani a me ke kukui uila.

Inā mākou e noʻonoʻo i ka ʻāpana o ka pilina ma waena o ka pad a me ka disc, a laila i ka mālamalama maikaʻi hiki iā ʻoe ke ʻike i ka nui o ka lining friction e waiho ana ma ka substrate pad.

ʻO ka maʻamau ka palena palena ʻo 2-3 mm. He pōʻino ke kaʻa hou aku. A ʻoi aku ka maikaʻi o ka lawe ʻole ʻana i kēia waiwai, ma hope o ke koena 4 mm ʻo ia ka manawa e hoʻololi i nā pads.

ʻOi aku ka paʻakikī o ka pilikia e ka aneane piha ʻole o ka loiloi ʻana i ka pā kūloko i hūnā ʻia ma lalo o ka caliper.

ʻOiai inā hiki ke ʻike ʻia mai ka hopena o ka disk, e hāʻawi kēia i ka ʻike liʻiliʻi, ua pau kēia wahi i ka ʻole, a hūnā ʻia hoʻi e ka ʻaoʻao i hana ʻia i ka wā e hoʻohana ai i ka pōʻai o ka disk. ʻO ia hoʻi, me ka ʻaʻahu ʻole o nā pads, ʻo ke aʻo ʻana i ka waho wale nō ʻaʻole e hāʻawi i kekahi mea.

ʻO ka mānoanoa o nā disc brake - pehea e ana a me ka mea e pono ai ma nā discs Audi A6 C5

ʻO ka mea pōmaikaʻi, hāʻawi pinepine nā mea hoʻolālā i kahi hōʻailona palena ʻaʻahu uila a i ʻole acoustic. Hoʻomaka ka poloka e uwē a i ʻole e hoʻomālamalama i ka hōʻailona ma ka dashboard.

Nā ʻōlelo paipai no ka hoʻololi ʻana i nā pad brake

ʻO ka hoʻolālā o nā kaʻa ma nā mīkini a pau e like, no laila hiki ke ʻike ʻia nā hiʻohiʻona o ka mālama ʻana i nā ʻāpana.

1. Hoʻololi mau ʻia nā pads i nā pūʻulu ma ka axle hoʻokahi. ʻAʻole ʻae ʻia ka hoʻololi ʻana iā lākou i kēlā me kēia manawa me ka ʻaʻahu like ʻole.
2. I ka hoʻololi ʻana i nā pads, pono e lubricate i kā lākou mea alakaʻi holoʻokoʻa me kahi haku mele kiʻekiʻe.
3. Hoʻopili ʻia ka nānā pono ʻana i ke kūʻokoʻa o ka neʻe ʻana o nā pistons i nā cylinders hydraulic.
4. Inā ʻaʻahu like ʻole ka diski a ʻoi aku paha i nā palena o kona geometry, pono e hoʻololi ʻia ka disk me ke ʻano ʻole.
5. I ka wā e hoʻokuʻu ai i nā pistons ma lalo o nā pads hou, pono e lawe ʻia nā ana e hoʻonui manuahi i ka pae wai i loko o ka waihona pahu master cylinder, a laila lawe i ka pae i ka maʻamau.
6. ʻO ka manawa mua āu e kaomi ai i ka pedal ma hope o ka hoʻokomo ʻana i nā pads, hāʻule ʻo ia, no laila ʻaʻole hiki iā ʻoe ke neʻe aku me ka ʻole o ke kaomi ʻana i ka pahu i nā manawa he nui.
7. I ka wā mua, e holo nā pads i loko, no laila ʻaʻole e hoʻihoʻi koke ʻia ka pono o nā kaʻa.
8. Pono nā mīkini pahu axle hope i ka hoʻoponopono lima lima.

Pehea e hoʻololi ai i nā pale pale mua Audi A6 C5

ʻAʻohe mea liʻiliʻi i ka mālama ʻana i ka ʻōnaehana brake. Mai manaʻolana ʻo ka hoʻololi ʻana i nā pads e hoʻopau i nā pilikia āpau.

I nā hihia koʻikoʻi, pono ʻoe e hoʻomaikaʻi nui i nā mea āpau o ka ʻōnaehana, nā hoses, ka wai hana, a hiki i ka hoʻololi ʻana i nā calipers, ʻaʻole pili i ke kumukūʻai. I kēlā me kēia hihia, eʻoi aku ka pipiʻi o nā hopena.
