He aha ka mea i loko o ke kaʻa? He aha ka mea e hōʻike ai a pehea ka ʻokoʻa mai ka speedometer?

ʻIke mau ka mea hoʻokele kaʻa i kahi dashboard i mua ona, kahi e kau ʻia ai nā mea ana like ʻole. No laila, hōʻike ka speedometer i ka wikiwiki o kēia manawa, hōʻike ka tachometer i ka nui o nā kipi i kēlā me kēia minuke e hana ai ka crankshaft. Aia kekahi mau hōʻailona o ke kaomi ʻaila, ka uku pākaukau, ka mahana antifreeze. Loaʻa i nā kaʻa kaʻa a me nā kaʻa kaʻa kaʻa e hōʻike ana i ke kaomi ʻana o ke kaʻa kaʻa, ke kaomi kaʻa, a me nā ana wela aila lawe.

Aia kekahi mea hana maʻamau ma waena o ka tachometer a me ka speedometer, e hōʻike ana i ka mileage i holo ʻia e ke kaʻa. Kapa ʻia kēia mea he odometer - he mea pono loa. ʻO ka mea nui, inā kūʻai ʻoe i kaʻa i hoʻohana ʻia, pono ʻoe e nānā inā wili ka mileage. Pehea e hana ai - ua haʻi mua mākou ma Vodi.su ma kekahi o nā ʻatikala ma mua.

Pehea ia hana

I ka ʻike ʻana i ka radius o ka huila a me ka wikiwiki o ke kaʻa, hiki iā ʻoe ke hoʻohana i kahi ʻano maʻalahi e hoʻoholo ai i ka wikiwiki angular e neʻe ai kahi kiko i koho ʻia ma ka pōʻai a puni ke kikowaena. ʻAe, me ka hoʻohana ʻana i kēia mau ʻikepili āpau, hiki iā ʻoe ke hoʻoholo maʻalahi i ke ala e hele ai ke kaʻa, kaʻa a i ʻole kaʻa.

ʻOiaʻiʻo, ua hiki mai ka manaʻo o ka hana ʻana i kēia mea maʻalahi i ka manaʻo o ka Helene mathematician Heron o Alexandria, i noho i ke kenekulia mua o ko mākou au. Wahi a nā kumu ʻē aʻe, ʻo ka mea mua i hoʻomālamalama ʻia e ka manaʻo o ka odometer ʻo ia paha ʻo Archimedes kaulana, a i ʻole ke akeakamai Kina a me ka mea noʻonoʻo ʻo Zhang Heng. I kēlā me kēia hihia, ʻike maopopo ʻia aia ma ka III Art. n. e. Ua hoʻohana ikaika ka Pākē i kēia mea hana e ana i ka mamao o ka hele ʻana. A kapa ʻia lākou ʻo "ke kuʻekuʻe o ke ala i hele ai ke kaʻa."

I kēia lā, hoʻokomo ʻia kēia mea hana ma nā kaʻa a me nā kaʻa. Ke hana nei ia ma ke kumu maʻalahi: ua hoʻopili ʻia ka counter ma o kahi sensor i ka huila. Hoʻoholo ka mea ʻike i ka wikiwiki o ka huli ʻana, a helu ʻia ka mamao i hele ai ma ka CPU.

Hiki i ka odometer ke:

• mechanical - ke koho maʻalahi;
• electromechanical;
• ma ka uila.

Inā loaʻa iā ʻoe kahi kaʻa hou a i ʻole ka liʻiliʻi, a laila ua hoʻolako ʻia me kahi odometer uila, e ana i ka mamao o ka huakaʻi ma muli o ka hopena Hall. Ua kākau mua mākou ma Vodi.su e pili ana i ka sensor Hall, e ana pololei ana i ka wikiwiki o ka rotation o ka crankshaft. ʻO ka ʻikepili i loaʻa he pololei loa, a he liʻiliʻi ka hapa o ke ana ʻana, ʻaʻole i ʻoi aku ma mua o 2 pakeneka (no ka uila) a me ʻelima pakeneka (no nā mea mechanical a me electromechanical).

He aha kāu e ʻike ai e pili ana i nā odometers?

ʻO ka maikaʻi o nā odometers uila ma mua o nā ʻano ʻoi aku ka holomua ʻaʻole i hoʻonohonoho hou ʻia ka odometer uila. Ma kahi hōʻailona mechanical, hana nā huila i ka pōʻai piha a hoʻihoʻi i ka zero. Ma ke'ano he kūlana,'oi aku ka mile ma mua o 999 tausani km. ʻaʻole hōʻike ʻia lākou. Ma ke kumu, hiki i nā kaʻa liʻiliʻi, ʻokoʻa nā kaʻa kaʻa a i ʻole nā ​​​​kaʻa kaʻa kaʻa, hiki ke uhi i kēlā mamao i kā lākou hana holoʻokoʻa.

Pono ʻoe e hoʻolohe i ka hōʻike ʻana o ka odometer i ka huina mile a me ka mamao i hele i kekahi manawa. Pili kēia i nā odometers uila a me mechanical. ʻO ka mea maʻamau, aia pololei ka hōʻailona ma ke kelepona o ka speedometer. No laila, manaʻo pinepine ʻia ʻo ka speedometer a me ka odometer hoʻokahi a me ka mea like. Hōʻike ka puka makani luna i ka huina mile, ʻo ka puka makani haʻahaʻa e hōʻike ana i ka mamao i hele ai i kēlā me kēia lā. Hiki ke maʻalahi kēia mau heluhelu.

I ke kūʻai ʻana i nā kaʻa i hoʻohana ʻia, e nānā mua nā mea hoʻokele i ka mileage i hōʻike ʻia e ka odometer. Aia kekahi mau hōʻailona e hiki ai iā ʻoe ke koho ua wili ʻia ka mileage ma kahi odometer mechanical. Ma ke kumu, ua aʻo nā haku i ka wili i nā mea uila. Akā, pono ʻoe e hoʻomaopopo i nā kaʻa o kēia wā, mālama ʻia nā ʻikepili āpau e pili ana i ka mokuʻāina o ke kaʻa i ka hoʻomanaʻo o ka kamepiula, kahi mea hiki ʻole ke hoʻomaʻemaʻe. ʻO ia ke kumu, inā e kū mai kekahi kānalua, pono ʻoe e hōʻole e kūʻai, a i ʻole e hoʻokele i ke kaʻa no kahi hōʻoia piha a ʻike i kona mile mile maoli.

Ke hoʻouka nei…
