Embodiment 1
[0042] Such as figure 1 As shown, the hybrid electric vehicle power drive system based on the double planetary row provided by the present invention is characterized in that the system includes: a power output device, a brake, a power source, a first planetary row drive device, a second planetary row drive device and controller. The power source wherein comprises a first power source 1, a second power source 13 and a third power source 14, the first power source is preferably an engine, the second power source and the third power source adopt motors, and the second power source is hereinafter referred to as The motor 1 , the third power source is the motor 2 , and the brakes include a first brake 3 and a second brake 15 .
[0043] The first planetary row driving device adopted in the present invention includes a first sun gear 22, a first ring gear 6, a first planet carrier 4, and a first planetary gear 5 meshed with the first sun gear 22 and the first ring gear 6; The first...
Embodiment 2
[0057] Such as figure 2 As shown, on the basis of Embodiment 1, the first clutch 25 is added, that is, the second ring gear 7 forms a clutch connection with the fourth drive shaft 21 through the first clutch 25, and the controller controls the first brake 3, the second brake 15 and The first clutch 25 is controlled individually or in combination. The control system is in pure electric mode, input power split mode, compound power split mode and parallel hybrid drive mode. The specific typical working modes are shown in Table 2.
