Abstract

The invention relates to a hybrid power system which comprises an engine, a first motor, a second motor, a clutch, a transmission mechanism with a transmission shaft and a battery, wherein the first motor and the second motor are respectively connected to the battery, a motor shaft of the second motor is connected with the transmission mechanism, the output shaft of the engine is connected with the motor shaft of the first motor, the motor shaft of the first motor is a hollow shaft, the clutch is arranged in the motor shaft of the first motor, the drive part of the clutch is connected with the inner wall of the motor shaft of the first motor, and the driven part of the clutch is connected with the transmission shaft. The hybrid power system ensures that the internal structure of the vehicle is compact, simplifies the structure, and improves the space utilization ratio in the vehicle.

Description

technical field [0001] The present invention relates to a hybrid power system, and more particularly, to a hybrid power system capable of working in a pure electric mode, a pure engine mode and a hybrid power mode. Background technique [0002] In today's world, human beings are facing two major challenges: energy scarcity and environmental degradation. Traditional vehicles are increasingly troubled by the oil crisis. Energy conservation and environmental protection have gradually become the development theme of the vehicle industry. Hybrid vehicles have become the subject of current vehicle industry development because of their excellent performance in energy saving and environmental protection. The structure of the hybrid power system determines the types of working modes that can be realized. Therefore, in order to realize multiple working modes, the hybrid power system usually has a relatively complicated structure. This complex structure causes the hybrid system to occ...
