Pehea e koho ai i ka aila fork

Hoʻohana ʻia nā ʻaila fork no ka mālama ʻana i ka hana o nā kaʻa kaʻa kaʻa mua a me nā mea hoʻopuʻi. Ke manaʻoʻiʻo nei kekahi poʻe kaʻa he mea maikaʻi e ninini i kēlā mau kālā i loko o nā mea hoʻokele kaʻa. E ʻike kākou i nā hōʻailona a me nā ʻano o kēia hui ʻaila.

Nā kūlana hana o ka ʻōkole hoʻohāhā kaʻa kaʻa

ʻO ka ʻōpala mua he ʻelua ʻāpana tubular lōʻihi e kākoʻo ana i ka huila mua o ke kaʻa kaʻa. Ke neʻe nei kēia mau ʻāpana i luna a i lalo e hoʻopaʻi i nā ʻili alanui ʻole.

ʻAʻole like me ka haʻalulu kaʻa, ʻae ka hui pūnāwai i ka wāwae wāwae e paʻi a hoʻihoʻi hou, e hoʻomaikaʻi ai i ka holo a me ka traction. Loaʻa i kēlā me kēia paipu mua ma ka hapa nui o nā kaʻa kaʻa he pūnāwai a me ka aila. I ka waenakonu o ke kenekulia i hala, he puna wale nō nā wāwae ʻōpuʻu i loko o ka paipu. Ke paʻi ka pūnāwai mai ka hopena ʻana, lele ka hope mua o ke kaʻa.

Ma hope o ka hoʻomohala ʻana o ka ʻōnaehana damping, ua ʻoi aku ka maʻalahi o ke kaʻina hana o ia ʻano rebound. Eia nō naʻe, no ka hoʻohaʻahaʻa ʻana i nā haʻalulu, pono e loaʻa kahi wai incompressible i loko o ka ʻōnaehana hiki ke hoʻopaʻa maikaʻi i nā haʻalulu haʻalulu: ʻaila fork. ʻO ka hoʻolālā maʻamau he paipu i loko o kēlā me kēia mea haʻalulu me nā lua a me nā keʻena e hoʻomalu i ka neʻe ʻana o ka aila.

Nā hana a me nā hiʻohiʻona

ʻOiai ka laulā o nā huahana i hāʻawi ʻia, he nui nā hemahema a me nā ʻano ambiguities i kāna kumu a me nā ʻāpana. No laila, ʻo nā koi hana no ka ʻaila fork e komo pū:

1. E hōʻoiaʻiʻo i ka maikaʻi o ka damping fork a me ka paʻa ma luna o kahi ākea ākea.
2. ʻO ke kūʻokoʻa o nā ʻano ʻaila mai ka hoʻolālā fork.
3. Kāohi i ka hoʻokumu ʻana o ka huʻa.
4. Hoʻokuʻu ʻia nā hopena corrosive ma nā ʻāpana metala o ka puʻu haʻalulu a me ka ʻōpala.
5. Kemika inertness o ka haku mele 'ana.

ʻO nā ʻaila ʻaila kaʻa a pau he wai hydraulic, no laila, e hilinaʻi ana i ko lākou ʻano maikaʻi, ʻo kekahi mau ʻaila ʻenehana kumu nui e like me GOST 20799-88 me kahi viscosity kūpono hiki ke hoʻohana. E ʻoluʻolu e hoʻomaopopo i ka piʻi ʻana o ka viscosity o ka ʻaila, e hoʻi mālie ka lāʻau i kona kūlana mua. Ma ka ʻaoʻao ʻē aʻe, i ka piʻi ʻana o ka viscosity, piʻi ka hana o ka aila, ʻoi aku hoʻi i ka wā e holo ai ma nā alanui ʻino, no nā kaʻa motocross.

Pehea e koho ai i ka aila fork?

ʻO ka mea mua, no kona viscosity. E like me kāu e ʻike ai, ua ana ʻia ka viscosity kinematic i nā keneta (cSt) a hōʻike i ka nui o ka kahe o ka wai ma o kahi paipu kūlana o kekahi ʻāpana. I ka hoʻomaʻamaʻa ʻana, ʻo ka nui i hoʻohana pinepine ʻia he mm2/s.

Hoʻopili ʻia nā ʻaila fork i ka American Society of Automotive Engineering (SAE), e pili ana i nā waiwai viscosity i kahi mahana i hāʻawi ʻia (maʻamau 40 ° C) i ka nui o ka huahana a me ke kaumaha. Weight in English weight; Mai ka leka mua o kēia huaʻōlelo, ua hoʻokumu ʻia nā inoa o nā ʻaila ʻaila. No laila, i ka wā e noʻonoʻo ai i nā aila no nā kaʻa kaʻa o nā hōʻailona 5W, 10W, 15W, 20W, etc., pono e hoʻomanaʻo ʻia, no ka laʻana.

Hoʻoholo ʻia ka nui o ka aila i loko o ka ʻōpala e kahi kūlana ʻoihana i hoʻohana ʻia i nā ʻōnaehana hydraulic i kapa ʻia ʻo Saybolt Seconds Universal (SSU). ʻO ka mea pōʻino, ʻo ka makemake o nā mea hana nui e alakaʻi pinepine i ka huikau ma nā lepili ʻaila fork. Ua hoʻokumu ʻia ka hoʻohālikelike ʻana o nā ʻāpana viscosity:

Kuhi Kuhi	Waiwai viscosity maoli, mm2/s ma 40 °C, e like me ka ASTM D 445 no nā huahana branded
Haʻalulu pōhaku	wai molybdenum	Motul	ʻO ka ʻaila huila heihei Motorex
5 W	16.1	17.2	18	15.2
10 W	33	29,6	36	32
15 W	43,8	43,9	57	46
20 W	-	-	77,9	68

He aha ka mea hiki ke pani i ka ʻaila fork?

Hoʻohana ʻia kahi pālākiō viscosity ʻoi aku ka maʻalahi no ka calibrate i ka ʻaila, no laila ma ka hoʻomaʻamaʻa hiki iā ʻoe ke kiʻi i kahi 7,5W a i ʻole 8W maʻamau "no ʻoe iho" ma ka hui ʻana i nā aila ʻoihana maʻamau i nā ʻāpana i koi ʻia.

No ka hana o ka huahana i nā kūlana hana kūikawā, ʻaʻole ia ka waiwai viscosity ponoʻī ka mea nui, akā ʻo ka mea i kapa ʻia ʻo viscosity index. Hōʻike maʻamau ia ma ka Saybolt Seconds Universal Scale (SSU) ma 100°C. E ʻōlelo kākou i nā helu ma ka pahu i heluhelu ʻia 85/150. ʻO ia ke ʻano o ka waiwai SSU o ka ʻaila ma 100 ° C he 85. A laila ana ʻia ka viscosity o ka ʻaila ma 40 ° C. ʻO ka helu ʻelua, 150, he waiwai e hōʻike ana i ka ʻokoʻa o ka kahe kahe ma waena o nā mahana ʻelua, kahi e hoʻoholo ai i ka index viscosity i koi ʻia.

He aha ka pili o kēia me nā ʻoki kaʻa? ʻO ke kuʻi ʻana i hana ʻia e ka paheʻe ʻana o nā ʻāpana metala a me ka neʻe ʻana o ka ʻaila i hope a i waho e hoʻonui ai i ka mahana i loko o ka hui. ʻOi aku ka paʻa mau o ke kaumaha o ka ʻaila, ʻoi aku ka liʻiliʻi o ka loli ʻana o ka hoʻoheheʻe ʻana i ka fork.

No laila, hiki ke hoʻololi i ka ʻaila fork me ka ʻaila ʻenehana ma ka hoʻohui ʻana i kāna mau māka e like me nā kūlana hana o kāu kaʻa.

Me kekahi mau hoʻopaʻa ʻana, hiki ke hoʻohana ʻia kēia kumu no nā kaʻa ʻē aʻe (koe naʻe nā kaʻa kaʻa heihei).
