Embodiment 1

[0024] This embodiment provides a vehicle, including a vehicle body and a planetary row hybrid power system. Since the vehicle body belongs to conventional technology, it will not be described in detail here. The following will focus on the planetary row hybrid power system.

[0025] The planetary row hybrid power system includes an engine 1, a front power mechanism, a first clutch 7 and a rear power mechanism. Wherein, the front power mechanism includes a front planetary row and a first motor 3. In this embodiment, the first motor 3 is an ISG motor, and the front planetary row includes a front sun gear 6C, a front planetary carrier 6B and a front ring gear 6A. The rear power mechanism includes a rear planetary row, a second motor 9 and a system output shaft 10. In this embodiment, the second motor 9 is a driving motor, and the rear planetary row includes a rear sun gear 8C, a rear planetary carrier 8B and a rear ring gear 8A. like figure 1 As shown, the first motor 3 is conn...

Embodiment 2

[0044] This embodiment provides a vehicle, including a vehicle body and a planetary row hybrid power system. The difference between the planetary row hybrid power system in this embodiment and the planetary row hybrid power system in the first vehicle embodiment is that the front planetary carrier 6B is connected to one end of the first lock-up clutch 4 , and the other end of the first lock-up clutch 4 Connect the front ring gear 6A, such as figure 2 shown. Except for the setting position of the first lock-up clutch 4, the other structures of the two systems are the same, and the working process and realized working mode of the planetary row hybrid power system in this embodiment are the same as those in the first embodiment of the vehicle. The planetary row hybrid power system is all the same, so it will not be described in detail in this embodiment.

Embodiment 3

[0046] This embodiment provides a vehicle, including a vehicle body and a planetary row hybrid power system. The difference between the planetary row hybrid power system in this embodiment and the planetary row hybrid power system in the first vehicle embodiment is that the front sun gear 6C is connected to one end of the first lock-up clutch 4 , and the other end of the first lock-up clutch 4 Connect the front ring gear 6A, such as image 3 shown. Except for the setting position of the first lock-up clutch 4, the other structures of the two systems are the same, and the working process and realized working mode of the planetary row hybrid power system in this embodiment are the same as those in the first embodiment of the vehicle. The planetary row hybrid power system is all the same, so it will not be described in detail in this embodiment.

Abstract

The invention relates to a planet row hybrid power system and a vehicle. The system comprises an engine, a front power mechanism and a rear power mechanism, wherein the front power mechanism comprisesa front planet row, a first lock-up clutch and a first motor, the rear power mechanism comprises a system output shaft, the first lock-up clutch is arranged between any two elements of a front sun gear, a front planet carrier and a front gear ring of the front planet row. When the first lock-up clutch is combined, the two corresponding elements are locked together, the two elements rotate at thesame speed in the same direction, the rotating speed and the direction of the third element except the two elements are the same as those of the two elements, and the whole front planet row becomes adirect gear mechanism; when large torque output is needed, only the output torque of the engine needs to be increased to the same degree, and the output torque of the engine does not need to be increased to a larger degree, so that the possibility that the engine does not run in a high-efficiency area any more due to the fact that the output torque is too large is reduced, and then the running efficiency of the engine is improved.

Description

technical field [0001] The invention relates to a planetary row hybrid power system and a vehicle. Background technique [0002] Parallel hybrid systems have huge performance advantages over series hybrid systems and parallel hybrid systems. The current hybrid power system mainly uses a planetary row as a power splitting device. For example, a Chinese utility model patent document with the authorized announcement number CN205706147U discloses a hybrid power system, including an engine, a front power mechanism and a rear power mechanism. The front power mechanism Including the front planetary row and the first motor, the rear power mechanism includes the system output shaft, the first motor is connected to the front sun gear of the front planetary row, the front sun gear is provided with a brake, and the power output end of the engine is connected to the front planetary carrier of the front planetary row , the front ring gear is connected to the rear power mechanism. The hy...
