Embodiment 1
[0035] like figure 1 and 2 As shown, Embodiment 1 of the present invention is a single-motor multi-mode hybrid power system, comprising an engine 1, a motor 2, a first transmission system 3, a second transmission system 4 and a shift actuator 5, the first transmission system 3 It includes a motor power input shaft 31, a large sun gear connecting shaft 32, an engine power input shaft 33 and a small sun gear connecting shaft 34. The second transmission system 4 includes a large sun gear 41 and a small sun gear 42. In the embodiment of the present invention Among them, the second transmission system is a Ravina planetary gear mechanism, in which the large sun gear 41 and the small sun gear 42 adopt a segmented structure, so that the shifting is smoother.
[0036] The shift actuator 5 includes a first clutch 51 and a second clutch 52 .
[0037]One end of the motor power input shaft 31 is connected to the motor rotor 22 , the other end of the motor power input shaft 31 is connect...
Embodiment 2
[0095] like image 3 As shown, Embodiment 2 of the present invention is a preferred embodiment of Embodiment 1, and the difference from Embodiment 1 is that a first planetary reduction mechanism is provided between the motor power input shaft 31 and the large sun gear connecting shaft 32 9. The first planetary deceleration mechanism 9 includes a first deceleration sun gear 91, a first deceleration planetary gear 92 and a first deceleration ring gear 93,
[0096] The first deceleration sun gear 91 is connected to the motor power input shaft 31 , the first deceleration ring gear 93 is fixed on the housing 8 , and the first deceleration planetary gear 92 is supported on the large sun gear through bearings. On the connecting shaft 32, the first deceleration planetary gear 92 meshes with the first deceleration sun gear 91 and the first deceleration ring gear 93 respectively, and the first planetary deceleration mechanism 9 is used to increase the motor driving torque and reduce the...
Embodiment 3
[0098] like Figure 4 As shown, Embodiment 3 of the present invention is a preferred embodiment of Embodiment 1, and the difference from Embodiment 1 is that a second planetary reduction mechanism 10 is provided between the motor power input shaft 31 and the large sun gear connecting shaft 32, The second planetary deceleration mechanism 10 includes a second deceleration sun gear 101 , a second deceleration planetary gear 102 , a second deceleration ring gear 103 and a second deceleration planet carrier 104 ,
[0099]The second deceleration sun gear 101 is connected to the motor power input shaft 31, the second deceleration ring gear 103 is connected to the large sun gear connecting shaft 32, and the second deceleration planetary gears 102 are respectively connected to the first deceleration gear 102. The second deceleration sun gear 101 meshes with the second deceleration ring gear 103 , the second deceleration planetary gear 102 is supported on the second deceleration planeta...
