I. Isi ihe dị na Axle draịva eletriki: "Ebe Ike" agbakwunyere

Axle draịva eletriki nwere modulu isi anọ: ​moto draịva, ihe na-ebelata (ma ọ bụ nnyefe), ọdịiche, na ọkara shaft, yana ụfọdụ ụdị na-eji njikọta "atọ n'ime otu" ma ọ bụ "ọtụtụ-n'ime otu" (dịka ọmụmaatụ, moto + ihe na-ebelata + ihe njikwa) maka ime ka ọ dị mfe.

Moto draịva: Ọtụtụ na-eji injin magnet synchronous na-adịgide adịgide (PMSMs) iji gbanwee ike eletriki ka ọ bụrụ ike igwe, na-ewepụta ike dị elu (10,000-20,000 rpm), ike dị ala (100-300 N·m).

Mbelata: Otu gia ma ọ bụ nke nwere ọtụtụ ogbo nke "na-ebelata ọsọ ma na-eme ka ike dịkwuo elu," na-agbanwe ọsọ dị elu nke moto ahụ gaa na obere ọsọ achọrọ maka wiil (≈1,500-3,000 rpm) na ike dị elu (1,000-3,000 N·m).

Ihe dị iche: Na-enye wiil aka ekpe na aka nri ohere ịtụgharị n'ọsọ dị iche iche (dịka ọmụmaatụ, wiil mpụta na-agbagharị ngwa ngwa mgbe a na-atụgharị ya), na-egbochi ihicha taya ma na-eme ka ọ dị mfe ịgbanwe.

Ọkara Ogwe: Ogwe siri ike nke na-ejikọ differential na wiil, na-ebuga torque na ibu wiil na-akwado ya.

II. Ụkpụrụ Ọrụ nke Axle Draịva Eletriki: Nzọụkwụ Anọ nke Nnyefe Ike

1. Ntinye Ike Eletriki:Batrị lithium dị elu (300-800V DC) na-enye ike DC, nke onye njikwa moto (gụnyere inverter) na-agbanwe ka ọ bụrụ AC nke atọ ma na-etinye ya n'ime moto draịva. Onye njikwa ahụ na-agbanwe ike mmepụta site na bọs CAN, na-eji data oge dị adị dị ka akara pedal accelerator, ọsọ ụgbọ ala, na ọnọdụ chajị batrị (SOC) (dịka ọmụmaatụ, ịkpọ oku maka mwepụta kachasị elu n'oge ngwa ngwa).

2. Mgbanwe Elektrọnik: Ntinye AC nke usoro atọ na windings stator nke moto ahụ na-emepụta oghere magnetik na-agbagharị (RMF) yana ọsọ ns= 60f/P(f: ugboro ugbu a; p: pole pairs). Rotor (etinyere ya na magnet na-adịgide adịgide) na-agbaso RMF n'ihi "ụkpụrụ enweghị mmasị kacha nta," na-eme ka ọsọ rotor nr na ns jikọọ iji nweta mgbanwe "eletriki → mekanikal" (arụmọrụ: 95%-97%).

3. Mbelata ọsọ na mmụba ike:Mmepụta ọsọ dị elu nke moto ahụ na-abanye na reducer, nke na-eji oke gia (dịka ọmụmaatụ, 8-12:1) iji belata ọsọ ma kwalite ike. Dịka ọmụmaatụ, ntinye 10,000 rpm na ike 200 N·m na-aghọ mmepụta 1,000 rpm yana ike 2,000 N·m mgbe oke 10:1 gasịrị, nke kwekọrọ na mkpa wheel drive.

4. Iwu dị iche iche na mmepụta ike: A na-ebufe ike mbelata ahụ na differential, nke na-ekesa torque n'etiti wiil aka ekpe na aka nri site na gia mbara ala - na-eme ka ọsọ na-agakọ na draịva ahịrị kwụ ọtọ ma na-ekwe ka ọsọ dị iche iche na-aga n'ihu iji gbochie ịdọkpụ taya. N'ikpeazụ, differential na-eziga ike na wiil site na ọkara shafts, na-akwali ụgbọala ahụ.

III. Uru Teknụzụ nke Axle Draịvụ Eletriki: Gịnị mere o ji bụrụ ọkọlọtọ na EV?

Ma e jiri ya tụnyere axles ICE ọdịnala (naanị ihe ndị na-ebelata ihe + ihe dị iche iche), nhazi axle draịva eletriki na nke nwere ọgụgụ isi na-enye uru atọ dị mkpa:

Arụmọrụ dị elu: Na-ewepụ ihe njide, nnyefe ọsọ ọsọ, na ihe ndị ọzọ, na-ebelata usoro nnyefe site na 30% ma na-ebelata mfu ike site na 15%-20%—na-agbatị oke ozugbo (dịka ọmụmaatụ, EV nwere axle draịva eletriki na-eru ihe karịrị 600km).

Nzaghachi ngwa ngwa: Ọkụ ike moto na-arị elu n'ime sekọnd 0.1, ejikọtara ya na njikọ gia ngwa ngwa nke onye na-ebelata ya, na-enye ọsọ dị elu (dịka ọmụmaatụ, Tesla Model 3 na-enweta 0-100km/h na sekọnd 5.6).

Mkpọtụ dị ala: Na-ewepụ ihe ndọda na-agbanwe gia site na nnyefe ọsọ dị iche iche, mekaniki dị mfe na-ebelata mkpọtụ — na-ebelata mkpọtụ ụlọ site na 5-8 dB maka njem dị mma karịa.
