Problems solved by technology

[0003] Hybrid vehicles have the advantages of reducing fuel consumption and reducing exhaust emissions. Therefore, various hybrid systems including parallel, series and hybrid modes have been developed at home and abroad. Their performances have their own advantages and disadvantages, but no matter which one All these modes have a common shortcoming; that is, it increases the difficulty of motor installation, mainly because the axial length increases by 300-500mm, which greatly increases the difficulty of installation. In addition, due to the lengthening of the rear suspension length of the vehicle, it will inevitably affect the center of gravity and steering of the vehicle. stability
[0004] However, a large number of traditional cars on the market, especially buses with high energy consumption, use the engine as the sole power source for their transmission systems, and the structure of their transmission systems has been finalized. For power vehicles, it is necessary to redesign and install the power system of the whole vehicle, resulting in waste of the original transmission system and huge modification costs, which will restrict the transition from transmission vehicles to hybrid vehicles

Abstract

The invention provides a hybrid power system which comprises a gearbox and a hollow bearing-free motor, wherein the hollow bearing-free motor comprises a stator and a rotor mounted in the stator; the rotor comprises a turntable; the gearbox comprises an end cover and an output shaft; the stator is fixed with the end cover of the gearbox; the turntable is fixed with the output shaft of the gearbox. The hollow bearing-free motor is smartly designed, the stator is fixed with a gearbox shell and a flange at the output shaft end of the gearbox is fixed with the turntable of the rotor, so that the hybrid power system can be refitted for a common vehicle without increasing the axial length, the mounting difficulty problem of the motor is smartly solved, the refitting is convenient and the cost is saved.

Description

Technical field [0001] The invention relates to a power system of an automobile, in particular to a hybrid power system. Background technique [0002] With the increasing scarcity of energy and the increasingly prominent environmental problems, energy conservation and environmental protection have become an important topic worldwide. Due to the limitation of battery technology, pure electric vehicles have too high cost and low cruising range to meet people's needs. Existing traditional cars have limited potential for fuel saving and emission reduction. Therefore, energy-saving, environmentally-friendly, and highly efficient hybrid vehicles have become the development trend of the automotive industry. [0003] Hybrid vehicles have the advantages of reducing fuel consumption and reducing exhaust emissions. Therefore, various hybrid systems including parallel, series, and hybrid models have been developed at home and abroad. Their performance has advantages and disadvantages, but no ...
