Disclosed is a power train for an electric vehicle that may include an input shaft to which a motor is fixedly connected; a driving gear rotatably mounted on the input shaft; an output shaft disposed in parallel to the input shaft; a driven gear fixed to the output shaft and gear-engaged with the driving gear; a planetary gear set including first, second and third rotation elements wherein the first rotation element is fixedly connected to the input shaft and the second rotation element is fixedly connected to the driving gear, and the third rotation element is restrained from rotating; a friction clutch configured for selectively connecting the input shaft to the driving gear and configured for selectively connecting the input shaft to the driving gear; and a restraining device provided to the third rotation element to implement two states so that only one-way rotation of the third rotation element of the planetary gear set is restrained or two-way rotation thereof is restrained.
本发明涉及一种用于电动车辆的动力传动系,其可以包括:输入轴,电机固定地连接至输入轴;驱动齿轮,其可旋转地安装在输入轴上;输出轴,其与输入轴平行地布置;从动齿轮,其固定至输出轴,并且与驱动齿轮啮合;行星齿轮组,其包括第一旋转元件、第二旋转元件和第三旋转元件,其中第一旋转元件固定地连接至输入轴,第二旋转元件固定地连接至驱动齿轮,第三旋转元件的旋转受约束;摩擦离合器,其配置为将输入轴选择性地连接至驱动齿轮;以及约束装置,其设置于第三旋转元件,以实现两个状态,使得行星齿轮组的第三旋转元件的单向旋转受到约束或行星齿轮组的第三旋转元件的双向旋转受到约束。
