He aha ke ola pōkole o nā pale pale?

Nā mea hana kaʻa kaʻa kaʻa: He aha ke ola pōkole o nā pale pahu?

E like me nā mea a pau, emi ka ikaika o nā loulou intermolecular i nā wela kiʻekiʻe. ʻO ke kumu o ka braking ʻo ia ka ʻae ʻana i ka ikehu kinetic e hoʻololi ʻia i ka ikehu wela e ka friction e hoʻokō ai i ka braking (ka manaʻo kaulike o ka ikehu), no laila ka nui o ka wela i hana ʻia e ka pahu pahu a me ka friction disc e hōʻiliʻili ma ka ʻili o ka mea friction brake pad. ʻO ka pahu pahu mua i mea e hoʻokō ai i kēia kūlana wela kiʻekiʻe, ʻo ka pahu pahu e mālama i ka ikaika kūpono, Pono e koho i ka resin kūpaʻa kiʻekiʻe, ka graphite maʻemaʻe kiʻekiʻe, ka barium maʻemaʻe kiʻekiʻe. sulfate a me nā mea ʻē aʻe, a ʻo kēia mau mea e like me kāu koho wale ʻana i ka nui o ka lanahu mai kahi kaʻa kalapona, e piʻi nui ke kumukūʻai.

A me nā pads haʻahaʻa haʻahaʻa, ʻaʻole lākou e hoʻohana i kēlā ʻano mea maikaʻi, no laila ʻaʻole hiki iā lākou ke hōʻoiaʻiʻo i ke kūpaʻa i nā mahana kiʻekiʻe, a me ka piʻi ʻana o ka wikiwiki, ʻoi aku ka wela, ʻoi aku ka mahana, ʻoi aku ka ikaika o ka loulou, a laila e hōʻemi ana i ka hiki i ka braking, hōʻike ʻia e like me ka lōʻihi o ka braking. No laila, ʻaʻole i manaʻo ʻia ʻo nā pad brake hiki iā ʻoe ke hoʻokele ma 20 a 60 km / h i ke kūlanakauhale ʻaʻole i loaʻa iā ʻoe ka hana paʻa paʻa mamao ma ka wikiwiki kiʻekiʻe. Ke hoʻemi ʻia ka ikaika o ka loulou o ke kaulahao molecular i ka wela kiʻekiʻe, e hoʻolōʻihi ʻia kona ʻaʻahu, ʻo ia ke kumu i pōkole loa ai ke ola lawelawe o nā pad brake brand maʻamau i nā mauna a i ʻole i ka mokuʻāina o ka hoʻomaha koke.
