Ke kūʻai ʻana i kaʻa kaʻa, nīnau pinepine nā mea hoʻokele kaʻa, ʻoi aku ka maikaʻi o ke kūʻai ʻana i kaʻa kaʻa me ka nui a i ʻole ka liʻiliʻi o ke kaʻa hope? ʻOiaʻiʻo, maikaʻi lāua ʻelua. ʻO ke kī ke kūpono. No ka maʻalahi, ʻike nā mea hoʻokele kaʻa he liʻiliʻi ka lākiō o ka axle hope, ʻo ia hoʻi ka ikaika piʻi liʻiliʻi, ka wikiwiki a me ka hoʻohana haʻahaʻa; ka nui hope axle wikiwiki ratio 'o ia hoʻi ka ikaika piʻi ikaika, lohi māmā a me ka nui wahie hoʻohana.
Akā, no ke aha? Pono mākou e ʻike ʻaʻole wale i nā ʻoiaʻiʻo akā ʻo nā kumu hoʻi ma hope o lākou. I kēia lā, e kamaʻilio kākou me nā hoa hoʻokele e pili ana i ka ratio wikiwiki o ka axle hope o nā kaʻa!
He inoa maʻamau wale nō ka lākiō māmā axle hope. ʻO ka inoa hoʻonaʻauao ka ratio hoʻohaʻahaʻa nui, ʻo ia ka ratio gear o ka mea hoʻemi nui i ka axle kaʻa kaʻa. Hiki iā ia ke hoʻemi i ka wikiwiki ma ka pahu hoʻokele a hoʻonui i ka torque. No ka laʻana, inā he 3.727 ka lākiō o ke koʻi hope o kahi kaʻa, a laila, inā he 3.727 r/s ka māmā holo o ke kaʻa, e hoʻemi ʻia ia i 1r/s (hoʻohuli i kekona).
Ke ʻōlelo mākou he ʻoi aku ka ikaika o ke kaʻa me ka ratio hope axle wikiwiki, a ʻoi aku ka wikiwiki o ke kaʻa me ka liʻiliʻi liʻiliʻi, pono mākou e hoʻohālikelike i nā hiʻohiʻona like. Inā he mau hiʻohiʻona like ʻole lākou, he mea ʻole ke hoʻohālikelike ʻana i ka nui o nā ratios wikiwiki axle hope, a maʻalahi ke huki i nā hopena hewa.
No ka mea, ua hoʻohana ʻia ka axle hope i hui pū me ka pahu pahu, ʻokoʻa ka nui o ka wikiwiki o nā ʻano ʻokoʻa i loko o ka pahu pahu, a ʻo ka huina holo wikiwiki o ke kaʻa ka hopena o ka hoʻonui ʻana i ka ratio wikiwiki o ka pahu pahu a me ka ratio wikiwiki o ka. koki hope.
No ke aha e holo wikiwiki ai nā kaʻa me ka lākiō māmā axle hope?
Me ka noʻonoʻo ʻole i nā mea o waho e like me ka ukana, ke kū ʻana o ka makani, ke kūpaʻa piʻi, a me nā mea ʻē aʻe, a me ka noʻonoʻo wale ʻana i ka ratio hoʻouna, hiki iā mākou ke unuhi i ka wikiwiki o ke kaʻa ma o kahi ʻano:
ʻO ka māmā holo kaʻa = 0.377 × (ka wikiwiki hoʻopuka ʻenekini × radius kaʻa kaʻa) / (ka lākiō kaʻa pahu pahu × ka lākiō māmā axle hope)
Ma waena o lākou, ʻo 0.377 kahi helu paʻa.
No ka laʻana, inā ʻo ke ʻano hoʻohālike like o nā kaʻa māmā he kaʻa māmā A a me ke kaʻa māmā B, ua lako lākou me nā kaila radial 7.50R16, ʻo Wanliyang WLY6T120 manual transmission, me 6 mau mea i mua a me hoʻokahi mea hoʻohuli, ʻoi aku ka wikiwiki kiʻekiʻe, ʻoi aku ka wikiwiki. ʻO ka lākiō he 0.78, ʻo ka lākiō māmā axle hope o ke kaʻa māmā A he 3.727, a ʻo ka lākiō māmā axle hope o ke kaʻa māmā B he 4.33.
A laila aia ka pahu pahu i ka mīkini kiʻekiʻe loa a ʻo ka wikiwiki o ka mīkini ʻo 2000rpm, e like me ke ʻano o luna, helu mākou i ka wikiwiki o ke kaʻa māmā A a me ke kaʻa māmā B. ʻO ka radius kaʻa o ka huila 7.50R16 ma kahi o 0.3822 mika (hiki ke kiʻi ʻia ka radius o ka huila o nā ʻano kikoʻī like ʻole e like me nā palena o ka huila.
Ka wikiwiki o ke kaʻa māmā A = 0.377 × (2000 × 0.3822) / (0.78 × 3.727) = 99.13 (km/h);
ʻO ka māmā holo kaʻa B = 0.377 × (2000 × 0.3822) / (0.78 × 4.33) = 85.33 (km/h);
No ke kumu hoʻohālike like o ke kaʻa, i ka wā o ka engine māmā he 2000rpm, ua theoretically deduced ka māmā holo o ka māmā kalaka A me ka liʻiliʻi hope axle wikiwiki lākiō hiki i 99.13km / h, a me ka mama o ka malamalama kalaka B me ka nui hope axle. ʻO 85.33km/h ka māmā holo. No laila, ʻoi aku ka wikiwiki o ka holo ʻana o ke kaʻa me kahi liʻiliʻi axle hope.
No ke aha i ikaika ai ka piʻi ʻana o nā kaʻa kaʻa me ka lākiō māmā axle hope?
ʻO ka hiki ke piʻi ikaika ʻo ia hoʻi, he ikaika kaʻa kaʻa kaʻa. ʻO ke kumu helu helu kumu no ka ikaika hoʻokele kaʻa:
Ka ikaika hoʻokele = (ka ʻenekini hoʻopuka puka × lākiō kaʻa × ka mea hoʻemi hoʻemi hope × ka hoʻoili ʻana i ka mīkini) / radius huila
No ke kaʻa māmā A a me ke kaʻa māmā B ma luna, ʻo ka radius huila o ka huila 7.50R16 ma kahi o 0.3937m (hiki ke kiʻi ʻia ka radius o nā kaila o nā kikoʻī like ʻole e pili ana i nā ʻāpana o ka huila. No ka maʻalahi, ʻōlelo pololei ʻia nā hopena ma aneʻi.
Inā makemake ʻoe, e hoʻolauna mākou iā ia ma hope). Inā ʻo ke kaʻa māmā A a me ke kaʻa māmā B ma ke kaʻa mua a ʻo 450 Nm ka pahu hoʻokuʻu mīkini, helu mākou i ka ikaika hoʻokele i loaʻa e ke kaʻa māmā A a me ke kaʻa māmā B i kēia manawa:
Kalaka māmā He ikaika hoʻokele = (450×6.32X3.72X0.98)/0.3937=26384.55 (Newtons)
Kaʻa māmā B ikaika hoʻokele = (450×6.32X4.33X0.98)/0.3937=30653.36 (Newton)
Aia ka ʻenekini i ka 1st gear a ʻo ka torque output engine he 450 Nm, ʻo ka ikaika hoʻokele i loaʻa e ke kaʻa māmā A ʻo 26384.55 Newtons, ʻo ia ka mea maʻamau e pili ana i 2692 kilokani (kg) o ka pahu (1 kg-ikaika = 9.8 Newtons); ʻO ka ikaika hoʻokele i loaʻa e ke kaʻa māmā B he 30653.36 Newtons, ʻo ia ka mea maʻamau e pili ana i 3128 kilokani (kg) o ka pahu (1 kg-ikaika = 9.8 Newtons). ʻIke loa, ʻoi aku ka ikaika o ke kaʻa B me ka lākiō māmā axle hope, a ʻoi aku ka ikaika o ka piʻi.
ʻO ka mea i luna aʻe he ʻano hoʻoheheʻe theoretical. No ka hoʻomaopopo ʻana, inā hoʻohālikelike ʻia ke kaʻa me ke kanaka, ua like ka ratio o ka wikiwiki axle hope me nā iwi wāwae. Inā liʻiliʻi ka ratio o ka wikiwiki o ka axle hope, hiki i ke kaʻa ke holo wikiwiki me kahi haʻahaʻa māmā a kiʻekiʻe ke alapine holo; inā nui ka lakene o ka māmā axle hope, hiki i ke kaʻa ke holo i mua me ka ukana kaumaha a haʻahaʻa ke alapine holo.
Mai ka loiloi ma luna, hiki ke ʻike ʻia he liʻiliʻi ka wikiwiki o ka axle hope, liʻiliʻi ka ikaika piʻi, a haʻahaʻa ka hoʻohana ʻana i ka wahie; ʻO ka nui o ka lākiō o ka axle hope, ikaika ka piʻi ʻana, lohi ka wikiwiki, a kiʻekiʻe ka hoʻohana ʻana i ka wahie.
I ka mākeke kūloko o kēia manawa, ʻo ka hui ʻana o ka "hoʻokele kiʻekiʻe a me ka liʻiliʻi ka wikiwiki o ka axle hope" ka mea nui, a pili ia i nā hiʻohiʻona hou aʻe. ʻAʻole like me ka wā ma mua, he liʻiliʻi ka ikaika o ka ʻenekini, he nui nā ukana, a he nui nā alanui mauna a me nā ala lepo, no laila ua makemake nā kānaka e koho i kahi axle hope.
I kēia mau lā, hoʻokumu nui ʻia ka halihali i nā ukana maʻamau, logistic kūpono, a me nā alaloa. "ʻO ke ala wale nō e lanakila ai i nā ʻoihana kaua āpau ma ka honua ʻo ka wikiwiki." Ke holo nei kekahi kaʻa kaʻa ʻenekini kiʻekiʻe me ka māmā liʻiliʻi, me kahi axle hope liʻiliʻi a me nā mea hoʻokele o ka pahu pahu, ʻaʻole pono ke kiʻekiʻe loa ka wikiwiki o ka mīkini e hiki ai i ka wikiwiki ma mua o 90 mau mile i kēlā me kēia hola.
Eia kekahi, ʻike pū mākou i ka hopena o ka wikiwiki axle hope i ka hopena o ka hōʻemi ʻana i ka wikiwiki a me ka hoʻonui ʻana i ka torque. Inā lawa ka mana o ka mīkini kiʻekiʻe-horsepower a loaʻa iā ia iho ka torque nui a me ka mana pahū ikaika, hiki ke hoʻonāwaliwali ka hopena o ka hilinaʻi ʻana i ka lākiō nui o ka axle hope e hoʻonui i ka torque. Ma hope o nā mea a pau, hiki i ka pahu pahu ke pāʻani i ka hana like.
ʻO ke kiʻekiʻe-horsepower, high-speed-ratio hope axle he kiʻekiʻe loa ka hoʻohana ʻana i ka wahie a kūpono no ka hoʻohana ʻana i nā kūlana hana kūikawā e like me nā kaʻa hoʻolei, nā kaʻa huila sima, a me nā kaʻa e holo pinepine ana ma nā alanui mauna.
No laila, ke kūʻai mākou i kaʻa kaʻa, ʻoi aku ka maikaʻi o ke kūʻai ʻana i ka ratio axle hope nui a liʻiliʻi paha? Aia nō ia i kāu hoʻohana ponoʻī.
No kekahi mau ala kaʻa a me nā ukana i paʻa paʻa, ʻoi aku ka maʻalahi o ke koho ʻana i kahi kumu hoʻohālike me kahi ratio wikiwiki kūpono. No kekahi mau mea lawe kaʻa kaʻahele a puni ka ʻāina, ʻaʻole paʻa nā ala a me nā ukana, no laila paʻakikī ke koho. Pono ʻoe e koho maʻalahi i ka ratio wikiwiki e like me kāu hoʻohana ponoʻī.
