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.
本公开涉及一种电动车辆驱动设备。根据各种实施方式,电动车辆驱动设备可包括驱动马达、多个轴、包括行星齿轮组的多个齿轮、同步器和离合器。电动车辆驱动设备可以具有同轴结构,其中连接到驱动马达的输入轴与连接到车轮的输出轴同轴地设置,并且电动车辆驱动设备可以在改变速度时通过动力旁路路径连续地传递动力。电动车辆驱动设备可通过最小化换档冲击来改善空间可用性并改善换档感觉。
