Abstract

A power transmission apparatus for a vehicle includes: a first clutch and a second clutch, a first input shaft receiving rotary power of the engine through the first clutch and having a plurality of input gears, a second input shaft receiving rotary power of the engine through the second clutch, a planetary gear set having first rotary element connected with the second input shaft, second rotary element connected with the first input shaft, and third rotary element being directly connected with a transmission housing, a first transmission outputting mechanism to output the rotary power transferred from the first input shaft and a second transmission outputting mechanism to output the rotary power transferred from the first input shaft, a motor/generator transferring the rotary power to the first and second transmission outputting mechanisms, and a final deceleration mechanism finally decelerating the rotary power transferred from the transmission outputting device.

Dependent claims

A power transmission apparatus for a vehicle, comprising:

a power control device including a first clutch and a second clutch to control rotary power of an engine;
an input device including:
a first input shaft selectively receiving the rotary power of the engine through the first clutch and having a plurality of input gears which are integrally formed to the first input shaft;
and
a second input shaft disposed on an outer periphery of the first input shaft without rotary interference to selectively receive the rotary power of the engine through the second clutch;
a torque converting device formed by a planetary gear set having first, second, and third rotary elements, the first rotary element being connected with the second input shaft, the second rotary element being connected with the first input shaft, and the third rotary element being directly connected with a transmission housing to serve as a fixing element;
a transmission outputting device including:
a first transmission outputting mechanism disposed in parallel to the first input shaft to transmit and output the rotary power transferred from the first input shaft to a plurality of advance transmission ratios;
and
a second transmission outputting mechanism disposed in parallel to the first input shaft to transmit and output the rotary power transferred from the first input shaft to a plurality of advance transmission ratios;
an electric supplementary drive unit including a motor/generator performing both motor and generator functions transferring the rotary power to the first and second transmission outputting mechanisms;
and
a final deceleration mechanism finally decelerating the rotary power transferred from the transmission outputting device through a differential.
