A powertrain for a motorized vehicle includes a motor shaft connected to a motor, a first input shaft configured to be selectively connected to the motor shaft and provided with a first driving gear mounted on the first input shaft, a second input shaft configured to be selectively connected to the motor shaft and provided with a second driving gear mounted on the second input shaft, a planetary gear set connected to the first input shaft and mounted so as to allow power from the motor shaft to be supplied via a plurality of paths, a first driven gear mounted to a differential and configured to mesh with the first driving gear, and a second driven gear mounted to the differential and configured to mesh with the second driving gear.

Powertrain for motorized vehicle

An electric hydraulic pump for a transmission includes: a motor including a motor cover, a motor case coupled with the motor cover, and a stator and a rotor disposed within the motor cover and the motor case; and a pump including a pump case forming a pump chamber, and a gear rotor which is disposed within the pump chamber, connected with the rotor through a motor shaft and receives rotational power of the motor. In particular, a plurality of oil circulation holes are formed in the motor cover and a connecting hole is formed in the motor cover corresponding to the pump case, and an oil flow channel is formed within the pump case for connecting the connecting hole and an oil inlet of the pump chamber.

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.

Hybrid powertrain

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.
