Embodiment Construction

[0040] vehicle embodiment

[0041] This embodiment provides a vehicle, and the power system of the vehicle is a planetary row hybrid drive system. Since other components of the vehicle are not the focus of this application, the following will focus on the detailed description of the planetary row hybrid drive system.

[0042] The planetary row hybrid drive system as a whole includes two parts, the front power structure and the rear power structure, such as figure 2 As shown, the front power structure includes the engine 1, the front planetary row 4 and the first motor 3, and the rear power structure includes the rear planetary row 6 and the system output shaft.

[0043] The front planetary row 4 includes three ends, which are respectively called the front first end, the front second end and the front third end. Since the three ends of the front planetary row 4 are the front sun gear, the front planetary carrier and the front ring gear respectively, Therefore, the front first...

Abstract

The invention relates to a planetary row hybrid power driving system and a vehicle using the system thereof. The driving system comprises three lock-up clutches, an engine is in transmission connection with the front first end of a front planetary row, a first motor is connected with the front second end of the front planetary row, and a rear power structure which is connected to the front first end of the front planetary row through the first lock-up clutch. The front third end of the front planetary row is connected with a casing through the third lock-up clutch, and the front third end is also connected with the rear power structure through the second lock-up clutch. When the engine starts and stops, the first lock-up clutch is controlled to be separated, the second lock-up clutch is controlled to be separated, and the third lock-up clutch is locked. The front planetary row is mechanically separated from the rear power structure of the driving system, and only the front planetary row gears are transmitting torque, thereby reducing the number of the transmission torque gears. The driving system effectively reduces the gear vibration caused by the gear gap of the rear planetary row of the rear power structure and the main reduction end of the axle, thereby effectively reducing the vibration noise of the system when the engine starts and stops.

Description

technical field [0001] The invention relates to a planetary row hybrid driving system and a vehicle using the system, belonging to the technical field of planetary row hybrid power. Background technique [0002] In the face of increasingly serious environmental pollution and energy crisis, energy saving and environmental protection have become the theme of the times. Hybrid vehicles are favored by the public due to their excellent energy saving effects, unlimited mileage, and pure electric driving functions. Vehicle hybrid systems are divided into three types: series, parallel, and hybrid systems. Among them, the hybrid system requires secondary conversion of all energy, resulting in excessive energy loss, so it is relatively seldom used at present. The energy conversion of the parallel system is relatively small, but the engine cannot work at the highest phase rate for a long time. However, the hybrid system using a planetary mechanism can solve the shortcomings of the par...
