Problems solved by technology

[0003] At present, the existing power system integrating the motor and the transmission generally uses one shaft as the power input shaft of the motor and the transmission at the same time. Although the integration has been achieved to a certain extent, the degree of integration is still insufficient, and the transmission The traditional gear shifting mechanism is still used, which has a large volume and insufficient gear shifting efficiency, and needs further integration and modularization research

Abstract

The invention relates to a highly-integrated power system with a motor and a four-speed electromagnetic direct-drive transmission. The motor and the four-speed electromagnetic direct-drive transmission are highly integrated to commonly drive a shaft; by the application of the ''electricity-magnetism-power'' principle, electric energy can be converted into mechanical energy which drives the motor and the transmission to work; the motor and the transmission can be controlled by controlling current. The integrated system has the advantages of high working efficiency, compact structure and the like; the current requirement on integration of the power system of an automobile is met. The highly-integrated power system with the motor and the four-speed electromagnetic direct-drive transmission is suitable for being used in the technical field of the power systems of the automobiles; particularly, when the power system is applied to the technical field of purely electric automobiles, the driving mileage of the electric automobile can be effectively increased, and a technology foundation is laid for driving safety and intelligent development of vehicles.

Description

technical field [0001] The invention relates to the technical field of automobile power systems, and more specifically relates to a highly integrated power system of a motor and a four-speed electromagnetic direct drive transmission. Background technique [0002] In today's society, the demand for automobiles is increasing. While people pay attention to the power and comfort of automobiles, they also start to pay attention to the emission and energy consumption of automobiles. Environmental problems are becoming more and more serious, and energy problems are becoming more and more acute. Therefore, governments and manufacturers of various countries have also stepped up the development and research of electric vehicles. It is very important for the development of electric vehicles to develop a highly integrated power system suitable for electric vehicles. role. A highly integrated power system with a motor and a four-speed electromagnetic direct drive transmission, which can...
