I. Babban Abubuwan da ke Cikin Gashin Wutar Lantarki: Haɗin "Cibiyar Makamashi"

Aksali na tuƙi na lantarki ya ƙunshi manyan kayayyaki guda huɗu: injin tuƙi, mai ragewa (ko watsawa), bambancin ra'ayi, da rabin shaft, tare da wasu samfura suna ɗaukar haɗin "uku-cikin-ɗaya" ko "yawan-cikin-ɗaya" (misali, mai ragewa + mai sarrafawa) don ƙarin sauƙaƙawa.

Motar Tuki: Yawancinsu suna amfani da injinan maganadisu na dindindin (PMSMs) don canza makamashin lantarki zuwa makamashin inji, suna fitar da wutar lantarki mai sauri (10,000-20,000 rpm), ƙarancin ƙarfin juyi (100-300 N·m).

Mai ragewa: Saitin gear guda ɗaya ko mai matakai da yawa wanda ke "rage gudu da ƙara ƙarfin juyi," yana canza babban gudun motar zuwa ƙaramin gudu da ƙafafun ke buƙata (≈1,500-3,000 rpm) da babban juyi (1,000-3,000 N·m).

Bambancin: Yana bawa tayoyin hagu da dama damar juyawa a saurin gudu daban-daban (misali, tayoyin waje suna juyawa da sauri lokacin juyawa), yana hana goge taya da kuma tabbatar da sassaucin tuƙi.

Rabin Shaft: Shaft mai ƙarfi mai haɗa bambancin zuwa ƙafafun, yana watsa ƙarfin juyi da kuma nauyin ƙafafun da ke tallafawa.

II. Ka'idar Aiki ta Axle na Motar Lantarki: Matakai Huɗu na Canja Makamashi

1. Shigar da Makamashin Lantarki:Batirin lithium mai ƙarfin lantarki mai yawa (300-800V DC) yana samar da wutar lantarki ta DC, wanda mai sarrafa motar (gami da inverter) ke mayar da shi zuwa AC mai matakai uku sannan a ciyar da shi cikin injin tuƙi. Mai sarrafa yana daidaita wutar lantarki ta hanyar amfani da bas ɗin CAN, ta amfani da bayanai na ainihin lokaci kamar siginar pedal mai sauri, saurin abin hawa, da yanayin caji na baturi (SOC) (misali, yana kiran fitar da kololuwa yayin hanzarta sauri).

2. Canjin Lantarki: Shigar da AC mai matakai uku zuwa ga na'urorin stator na motar yana samar da filin maganadisu mai juyawa (RMF) tare da saurin ns= 60f/P(f: mitar yanzu; p: nau'ikan sanduna). Rotor (wanda aka haɗa da maganadisu na dindindin) yana bin RMF saboda "ƙa'idar rashin son kai mafi ƙaranci," yana daidaita saurin rotor tare da ns don cimma canjin "na lantarki → na inji" (inganci: 95%-97%).

3. Rage gudu da Ƙarfafa Ƙarfin Motsi:Fitowar babbar motar mai sauri tana shiga cikin na'urar rage gudu, wadda ke amfani da rabon gear (misali, 8-12:1) don rage gudu da haɓaka karfin juyi. Misali, shigarwar rpm 10,000 tare da karfin juyi 200 N·m ya zama fitarwa rpm 1,000 tare da karfin juyi 2,000 N·m bayan rabo 10:1, wanda ya dace da buƙatun tuƙi.

4. Tsarin Bambance-bambance da Fitar da Wutar Lantarki: Ana canja wurin ƙarancin wutar lantarki zuwa bambancin, wanda ke rarraba ƙarfin juyi tsakanin ƙafafun hagu da dama ta hanyar gears na duniya - yana daidaita gudu a cikin tuƙi madaidaiciya kuma yana ba da damar saurin bambanci yayin juyawa don hana jan taya. A ƙarshe, bambancin yana aika wutar lantarki zuwa ƙafafun ta hanyar rabin shafts, yana motsa abin hawa.

III. Fa'idodin Fasaha na Axle na Motar Wutar Lantarki: Me yasa Ma'auni ne a cikin EVs?

Idan aka kwatanta da axles na ICE na gargajiya (masu ragewa kawai + bambance-bambance), ƙirar axle na lantarki mai haɗaka da wayo yana ba da fa'idodi uku masu mahimmanci:

Ingantaccen Aiki: Yana kawar da maƙullan lantarki, watsawa mai saurin gudu da yawa, da sauran abubuwan haɗin gwiwa, yana rage sarkar watsawa da kashi 30% da kuma rage asarar makamashi da kashi 15%-20%—wanda ke faɗaɗa kewayon kai tsaye (misali, EVs masu axles na tuƙi na lantarki suna kaiwa tsawon kilomita 600).

Amsa Mai Sauri: Karfin juyi na injin zai kai kololuwa cikin daƙiƙa 0.1, tare da saurin haɗa gear na na'urar rage gudu, wanda hakan zai samar da ingantaccen hanzari (misali, Tesla Model 3 ya kai 0-100km/h cikin daƙiƙa 5.6).

Ƙaramin Sauti: Yana kawar da girgizar da ke canza gear daga watsawa mai saurin gudu da yawa, kuma makanikai masu sauƙi suna rage girgiza—yana rage hayaniyar ɗakin da 5-8 dB don samun sauƙin tafiya.

Kammalawa

Axle na tuƙi na lantarki shine "ƙarshen jijiya" na watsa wutar lantarki ta EV, yana ba da damar canza kuzari mai inganci na "na lantarki → na inji" ta hanyar aiki mai daidaitawa na motar, mai ragewa, bambancin, da rabin shaft. Tare da ci gaba a cikin haɗakarwa (misali, axle na "da yawa-cikin-ɗaya"), kayan aiki (misali, rabin shaft na carbon fiber), da kuma sarrafawa mai wayo (misali, daidaitawar haɗin gwiwa ta VCU), axle na tuƙi na lantarki na gaba za su ƙara inganta amfani da makamashi da aiki, suna zama muhimmiyar hanya ga sabbin motocin makamashi na duniya don cimma "tsawon zango da ƙarfi."
