摘要： A power train for an electric vehicle 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.

摘要： A hybrid powertrain may include a first shifting module including a motor input shaft having a motor directly connected to the motor shaft and provided to form two shifting stages having the largest gear ratios in sequence among a series of shifting stages; a second shifting module including an engine input shaft concentrically mounted with the motor input shaft and connected to an engine through a main clutch, and provided to form the remaining shifting stages of the series of shifting stages; a center synchro mounted to intermit the motor input shaft and the engine input shaft; and a continuous variable device provided to implement a state in which the first shifting module forms a gear ratio smaller than a shifting stage having a small gear ratio among the shifting stages of the first shifting module by a continuously controlled friction force.
