Abstract

The invention provides a driving motor. The driving motor comprises a casing and a stator and a rotor which are arranged inside the casing; a rotor spindle which is used for fixing a sun gear in a sleeve mode is formed in the middle of the rotor along the axial direction; an internal ring gear is installed inside the casing through a first brake; the sun gear and the internal ring gear are meshed with a planetary gear which is installed on a planetary frame; the middle of the planetary frame is fixedly connected with an output connecting shaft which is arranged along the axial direction; a second brake is arranged between the planetary frame and the sun gear. According to the driving motor, output torque of an output shaft of the rotor is reduced under the premise that the series-parallel hybrid power system normally operates and meanwhile the output connecting shaft satisfies larger output torque, so that the size of the driving motor and the stator and the rotor inside the driving motor is greatly reduced and meanwhile the driving motor is convenient to install and use. The invention also provides two series-parallel hybrid power systems which enable the integral size and weight of the series-parallel hybrid power system to be greatly reduced and the universality to be 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...
