Abstract: An electric vehicle includes a disc (300) fixed to a housing. The electric vehicle also includes a first shaft (100) connected to a motor and rotatable by the motor, and a second shaft (200) connected to a wheel and spaced apart from the first shaft (100). Further, the electric vehicle includes a hub (400) press-fitted to an outer circumference of the second shaft (200), and a sleeve (500) spline-coupled with an outer circumference of the hub(400). The sleeve (500) is slidable between the first shaft (100) and the disc (300). The electric vehicle operates in any one of a driving mode, a neutral mode, and a parking mode according to a position of the sleeve. (500)

Abstract: A motor may include a shield member that screens a magnetic field between a stator and a rotor, and a moving member that controls a position of the shield member in response to an electromagnetic interaction with the stator such that the screening of the magnetic field is configured to be selectively performed. The motor may prevent a generation of a counter electromotive force or regenerative braking.

Abstract: According to various embodiments, an electric vehicle driving apparatus may include a driving motor, a plurality of shafts, a plurality of gears including a planetary gear set, a synchronizer, and a clutch. The electric vehicle driving apparatus may have a coaxial structure in which an input shaft connected to the driving motor is disposed coaxially with an output shaft connected to a wheel, and may continuously transmit power through a power bypass path when changing a speed. The electric vehicle driving apparatus may improve a spatial usability and improve shifting feeling by minimizing shift shock.
