Abstract: An electric vehicle includes a disc fixed to a housing. The electric vehicle also includes a first shaft connected to a motor and rotatable by the motor, and a second shaft connected to a wheel and spaced apart from the first shaft. Further, the electric vehicle includes a hub press-fitted to an outer circumference of the second shaft, and a sleeve spline-coupled with an outer circumference of the hub. The sleeve is slidable between the first shaft and the disc. 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.

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.
