Abstract

The invention provides a driving motor which comprises a shell, a stator and a rotor. The stator and the rotor are arranged in the shell; a sun gear is fixedly sleeved on an output shaft of the rotor, an inner gear ring is fixedly connected into the shell, and both the sun gear and the inner gear ring are meshed with a planet gear mounted on a planet carrier; a through hole is axially formed in the middle of the rotor, and a rotatable output connecting shaft is arranged in the through hole; the planet carrier is fixedly mounted at an output end of the output connecting shaft. Output torque of the output shaft of the rotor can be reduced to the greatest extent while the requirement on high output torque can be met by the output connecting shaft of the driving motor, so that the size of the stator and the size of the rotor of the driving motor can be greatly reduced, the size and the weight of the driving motor can be greatly decreased, the driving motor is convenient to mount and use, and the service range of the driving motor is greatly increased. The invention further provides two series-parallel hybrid power systems. The driving motor and the series-parallel hybrid power systems have advantages that the integral sizes and the integral weights of the series-parallel hybrid power systems are greatly reduced, and the universality of the series-parallel hybrid power systems is improved.

Description

technical field [0001] The invention relates to a driving motor and a series hybrid power system, in particular to a driving motor with a large output torque and a series hybrid power system, belonging to the technical field of motors. Background technique [0002] With the continuous development of urban traffic, the demand for energy such as petroleum is also increasing day by day for vehicles driven by people. In order to effectively reduce the consumption of non-renewable energy sources such as petroleum, people have developed hybrid vehicles. [0003] Hybrid vehicles currently mainly use a hybrid system. The system as figure 1 As shown, it includes an engine 11 and a torsional shock absorber 12 and a generator 13 that are sequentially arranged on the output shaft of the engine 11, and the output shaft of the engine 11 is connected with the input end of the clutch 14, and the output end of the clutch 14 is connected with the drive motor 15 The rotor of the driving mot...
