Problems solved by technology
[0003] At present, the technical research on the integration of the motor and the transmission has begun, most of which use the motor shaft as the power input shaft of the transmission at the same time, and use the traditional shift mechanism to shift gears, which reduces the design and manufacturing costs of the power system and transmission system, and The transmission efficiency has been improved, but the integration of these technologies is insufficient, and there is still a lot of room for improvement

The invention discloses an asynchronous motor and double-speed electromagnetic direct-drive transmission integration system. An asynchronous motor and an electromagnetic direct-drive transmission are highly integrated; the same shaft is used as a driving shaft, so that the structure compactness and the power transmission efficiency of the system can be improved; the integrated system can fully exert the working characteristic of high adaptability of the asynchronous motor, so that the system can work stably under different working conditions; current is supplied to circuits of the asynchronous motor and the electromagnetic direct-drive transmission according to the ''electricity-magnetism-power'' principle; control over the work of the system is actually control over the current in the device, so that the work of the system can be controlled more precisely and efficiently. The asynchronous motor and double-speed electromagnetic direct-drive transmission integration system is suitable for being used in the technical field of power systems of 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 better technology foundation is laid for driving safety and intelligent development of vehicles. After the asynchronous motor and double-speed electromagnetic direct-drive transmission integration system is popularized and applied, the energy consumption of a driving device is greatly reduced, so that higher economic benefits can be achieved.
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 an asynchronous motor and a two-speed electromagnetic direct drive transmission. Background technique [0002] The "2016 Government Work Report" clearly stated that vigorously developing and promoting new energy vehicles, mainly electric vehicles, and developing efficient and energy-saving power systems suitable for electric vehicles will become one of the main issues in electric vehicle research. At present, most of the power system of electric vehicles still uses the power output by the motor to decelerate and increase torque through the transmission, and then transmit the power to the wheels. This patent will invent an integrated power system of an asynchronous motor and a two-speed electromagnetic direct drive transmission, shorten the power transmission path, improve the transmission efficiency of the car, and ca...
