The invention provides a DC motor and double-speed electromagnetic direct driving transmission integrated power system, highly integrating a DC motor and an electromagnetic direct driving transmission and using the same driving shaft. The DC motor is small in size to make the whole system be compact in structure, and meanwhile, the DC motor is high in efficiency, precision and controllability, so that better adaptability can be performed after the system is integrated, and the structure compactness and the transmission efficiency of the power system are improved. The integrated power system is suitable for the technical field of automobile power systems, and particularly the technical field of electric automobiles, can effectively increase the endurance mileage of an electric automobile and provides a better basis for the safe driving and efficient running of the automobile. After the integrated power system is input into actual production, the energy utilization rate of vehicles can be improved, and great economic benefits are brought.
Description
technical field [0001] The invention relates to the technical field of automobile power systems, and more specifically relates to an integrated power system of a DC motor and a two-speed electromagnetic direct drive transmission. Background technique [0002] With the development of society and the continuous improvement of the quality of life, people's requirements for the performance of automobiles are constantly increasing. At the same time, environmental problems are becoming more and more prominent, and people are also paying more attention to energy-saving vehicles. Electric vehicles use electric energy as the driving energy, have high transmission efficiency and low pollution emissions, and are especially concerned by consumers. At present, it is one of the hot research issues to realize the goal of saving energy and reducing energy consumption by highly integrating the power system of the car to improve the running efficiency of the car. This patent will invent the ...
