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, including an engine 1, a motor 2, a first transmission system 3, a second transmission system 4 and a shift actuator 5, and the first transmission system 3 Including motor power input shaft 31, large sun gear connecting shaft 32, engine power input shaft 33 and small sun gear connecting shaft 34, the second transmission system 4 includes large sun gear 41 and 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 to make the shifting more smooth.

[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 connected to the big ...

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 arranged between the motor power input shaft 31 and the large sun gear connecting shaft 32 9. The first planetary reduction mechanism 9 includes a first reduction sun gear 91, a first reduction planetary gear 92 and a first reduction 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 reduction planetary gear 92 meshes with the first reduction sun gear 91 and the first reduction ring gear 93 respectively, and the first planetary reduction mechanism 9 is used to increase the motor drive torque and reduce Motor Power.

Embodiment 3

[0098] like Figure 4 As shown, Embodiment 3 of the present invention is a preferred embodiment of Embodiment 1. 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 reduction mechanism 10 includes a second reduction sun gear 101 , a second reduction planetary gear 102 , a second reduction ring gear 103 and a second reduction 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 connection shaft 32, and the second deceleration planetary gear 102 is respectively connected to the first 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 planet carrier 104 by bearings, and one end of the s...

Abstract

The invention discloses a single-motor multi-mode hybrid power system and an automobile. The system comprises an engine, a motor, a first transmission system, a second transmission system and a gear shifting executing mechanism, wherein one end of the motor power input shaft is connected with the motor rotor, and the other end is connected with the large sun gear connecting shaft; the large sun gear connecting shaft is connected with a large sun gear; an engine power input shaft is connected with the driving end of the first clutch and the driven end of the second clutch into a whole and coaxially rotates; one end of the small sun gear connecting shaft is connected with the driven end of the first clutch, the other end of the small sun gear connecting shaft is connected with the small sungear, and the second transmission system combines power of the engine and power of the motor so as to achieve variable speed output of different driving modes and various gears. The system has the advantages of being simple in structure, easy to repair, fast in response to speed change and capable of improving transmission efficiency.

Description

technical field [0001] The invention belongs to the field of automobile transmission systems, and in particular relates to a single-motor multi-mode hybrid power system and an automobile. Background technique [0002] As the number of cars increases year by year, new energy vehicles, as a relatively environmentally friendly travel tool, are becoming more and more popular among consumers. With the increasingly stringent environmental protection measures around the world, hybrid vehicles have become a focus of automobile research and development because of their energy-saving and low-emission characteristics. Hybrid vehicles go to the gas station to refuel like gasoline vehicles, and there is no need to change the usage habits of the car. The fuel economy performance is high, and the driving performance is excellent. The engine of the hybrid car needs to use fuel, and when starting and accelerating, due to the assistance of the electric motor, it can reduce fuel consumption. ...
