Embodiment 1

[0022] This embodiment provides a vehicle, and the point of the invention lies in the planetary row hybrid power system in the vehicle. Therefore, although there are other components in the vehicle, these components will not be described in this embodiment. The following focuses on the planetary row hybrid system. The row hybrid system will be described in detail.

[0023] The planetary row hybrid power system includes two parts, namely the front power mechanism and the rear power mechanism, wherein the front power mechanism includes the engine 1, the first motor 3, the front planetary row, the first lock-up clutch 5 and the second lock-up clutch 8.

[0024] The front planetary row includes three ends, respectively called the front first end, the front second end and the front third end, because the three ends of the front planetary row are the front sun gear 6C, the front planetary carrier 6B and the front ring gear 6A , Therefore, the front first end, the front second end a...

Embodiment 2

[0053] This embodiment provides a vehicle, including a planetary hybrid power system. Compared with the structure of the power system in the first vehicle embodiment, the difference between the planetary hybrid power system and the structure of the power system in the first vehicle embodiment is only in the arrangement of the second lock-up clutch 8 In a different manner, in this embodiment, the second lock-up clutch 8 is disposed between the front second end and the front third end in the front planetary row. Based on the specific implementation given in the first embodiment of the vehicle, the second lock-up clutch 8 is specifically arranged between the front planet carrier 6B and the front ring gear 6A, such as image 3 shown. The other structural components of the power system are the same as those in the first embodiment of the vehicle, and will not be repeated here. Then, the control principle of the power system, each working mode and the torque relational expression i...

Embodiment 3

[0055] This embodiment provides a vehicle, including a planetary hybrid power system. Compared with the structure of the power system in the first vehicle embodiment, the difference between the planetary hybrid power system and the structure of the power system in the first vehicle embodiment is only in the arrangement of the second lock-up clutch 8 In a different manner, in this embodiment, the second lock-up clutch 8 is disposed between the front first end and the front third end in the front planetary row. Based on the specific implementation given in the first vehicle embodiment, the second lock-up clutch 8 is specifically arranged between the front sun gear 6C and the front ring gear 6A, such as Figure 4 shown. The other structural components of the power system are the same as those in the first embodiment of the vehicle, and will not be repeated here. Then, the control principle of the power system, each working mode and the torque relational expression in each workin...

Abstract

The invention relates to a planetary row hybrid power system and a vehicle. The power system includes an engine, first motors, a front planetary row, first lock-up clutches and second lock-up clutches; the engine is connected to the front second end of the front planetary row; the first motors are connected to the front first end of the front planetary row; the front first end is connected to a shell through the first lock-up clutches; and the second lock-up clutches have three different arrangement modes, and arrangement can be performed according to actual needs. The system has two engine direct drive modes, and can perform power switching according to actual needs and optimize the working points of the engine, so that economy can be enhanced; through the utilization of the two lock-up clutches, the problems, that the long-time direct driving of the engine cannot realized caused by the stalling of the first motors when existing power systems are in the engine direct drive modes, canbe solved; and the engine can directly drive the whole vehicle at a high speed when the vehicle drives in the high speed and the driving force demand of the whole vehicle is located at the efficient area of the engine, so that the efficiency of the power system can be enhanced.

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 mechanism as a power splitting device, and a hybrid power system based on a double planetary row is the existing mainstream power system. For example: a Chinese patent document with the authorized announcement number CN101318462B discloses a hybrid power system, including an engine, a first motor, a second motor, a front planetary row and a rear planetary row. The hybrid power system combines the advantages of the series-parallel hybrid power system, can realize stepless speed change, and can also realize several pure electric working modes and hybrid power working modes. However, for the engine direct drive mode, the form of the hybrid power system is limited, and power switching...
