Power transmitting apparatus for hybrid electric vehicle

A power transmitting apparatus for a hybrid electric vehicle comprising:

• an input device including a motor shaft selectively connected to an engine, a first input shaft selectively connected to the motor shaft and provided with at least one input gear fixedly disposed thereon, and a second input shaft disposed without rotational interference with the first input shaft and provided with at least one input gear fixedly disposed thereon;
• a motor/generator disposed on the motor shaft of the input device and operated as a motor or a generator;
• a selectively connecting device including a first clutch selectively connecting the motor shaft with the first input shaft, a second clutch selectively connecting the motor shaft with the second input shaft, and a third clutch selectively connecting the motor shaft with the engine;
• and
• a speed output device changing torque input from the first and second input shafts of the input device and outputting a changed torque,
• wherein a first input gear for achieving a seventh forward speed, a second input gear for achieving a first forward speed or a reverse speed, a third input gear for achieving a third forward speed, and a fourth input gear for achieving a fifth forward speed are fixedly disposed on the first input shaft, and
• wherein a fifth input gear for achieving a fourth forward speed or a sixth forward speed and a sixth input gear for achieving a second forward speed is fixedly disposed on the second input shaft.
