Title:
DRIVING APPARATUS FOR ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/030234
Kind Code:
A1
Abstract:
The present invention provides a driving apparatus for an electric vehicle, the driving apparatus comprising: a driving case having a driving shaft installed therein to rotate on its axis; a first rotor rotatably connected to the inside of the driving case while being mounted on one end of the driving shaft; a second rotor rotatably connected to the inside of the driving case while being mounted on an opposite end of the driving shaft; a first stator fixedly coupled to the driving case so as to be disposed outside the first rotor; a second stator fixedly coupled to the driving case so as to be disposed outside the second rotor; a first power transmitting part installed inside the driving case to transmit power of the first rotor to the driving shaft or to stop the transmission of power to the driving shaft; and a second power transmitting part installed inside the driving case to transmit power of the second rotor to the driving shaft or to stop the transmission of power to the driving shaft. As described above, the first rotor and stator and the second rotor and stator are installed inside the driving case to generate separate rotational forces, and the first and second power transmitting parts selectively transmit the respective rotational forces to the driving shaft so that the driving apparatus for an electric vehicle can implement optimal driving performance according to driving conditions of the electric vehicle. In addition, the driving apparatus occupies a small mounting space when being mounted in an electric vehicle thanks to the simple structure thereof, thereby facilitating the installation operation.
