Power transmitting apparatus for vehicle

A power transmitting apparatus for a vehicle, comprising:

• an electric supplementary drive unit operated as a motor or a generator;
• a torque converting device including a planetary gear set having first, second, and third rotation elements, wherein the first rotation element is connected to the electric supplementary drive unit, the second rotation element is directly connected to an engine, and the third rotation element is operated as an output element;
• an input device including a first input shaft directly connected to the second rotation element and provided with at least one input gear fixedly disposed thereon, and a second input shaft disposed on the same axis as the first input shaft without rotational interference with the first input shaft, directly connected to the third rotation element, and provided with at least one input gear fixedly disposed thereon;
• a direct coupling device selectively connecting two rotation elements among the first, second, and third rotation elements of the torque converting device so as to cause the torque converting device to become a direct-coupling state;
• and
• a speed output device converting torque of the input device and outputting the converted torque,
• wherein the speed output device includes first and second output shafts disposed in parallel with the first and second input shafts, and a plurality of speed gears operably connected to the first output shaft or the second output shaft selectively through synchronizing modules disposed on the first and second output shafts,
• wherein the torque converting device is a double pinion planetary gear set, the first rotation element is a sun gear, the second rotation element is a planet carrier, and the third rotation element is a ring gear, and
• wherein the direct coupling device is a clutch disposed between the first rotation element and the third rotation element.
