Abstract

The invention discloses a hybrid power system based on a single motor. The hybrid power system based on the single motor comprises an engine, a clutch and a battery; the battery is connected with themotor, the motor is connected with a transmission mechanism, the engine is connected with a first output shaft through the clutch, the first output shaft is connected with the transmission mechanism,and the first output shaft is provided with a P2 synchronizer; and the first output shaft is connected with a second output shaft, the second output shaft is provided with a P3 synchronizer, and the second output shaft is connected with a main reducing gear, a differential mechanism and wheels. P2 and P3 modes are achieved through a single motor system, the space utilization rate can improved greatly, the fuel consumption and emission of a whole vehicle are reduced, and the system is low in cost and convenient to achieve.

Description

technical field [0001] The invention relates to a hybrid power system, in particular to a single motor-based hybrid power system. 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 occupy a relatively large space, which greatly reduces the space utilization rate inside...
