发明名称 Wheel hub motor
摘要 An electric vehicle driving device 10 includes a first motor 11, a second motor 12, a first planetary gear mechanism 20, a second planetary gear mechanism 30, a clutch device 40, and a wheel bearing 50. The first planetary gear mechanism 20 is a planetary gear device of single pinion type. The second planetary gear mechanism 30 is a planetary gear device of double pinion type. The first motor 11 is connected to a first sun gear 21 and a second sun gear 31. The second motor 12 is connected to a first ring gear 24. The clutch device 40 is connected to a first carrier 23. A second carrier 33 is connected to the first ring gear 24. A second ring gear 34 is connected to the wheel bearing 50.
