Hybrid power train for vehicle

A hybrid power train for a vehicle, comprising:

• an input shaft selectively receiving power of an engine;
• an engine side driving gear provided at the input shaft;
• an output shaft disposed parallel to the input shaft;
• an engine side driven gear provided at the output shaft so as to be engaged with the engine side driving gear;
• a motor side driving gear installed to be rotated by a motor and separated from the input shaft to be rotatable independently from the input shaft while forming a concentric axis with the input shaft;
• a motor side driven gear rotatably provided at the output shaft so as to be engaged with the motor side driving gear;
• a clutch unit installed to switch a state in which the motor side driven gear is fixed to the output shaft;
• an engine clutch provided between the input shaft and an engine shaft of the engine so as to intermit power to the input shaft;
• a power generation driving gear provided at the engine shaft;
• a power generation driven gear rotatably installed while forming a concentric axis with the engine shaft and connected to a generator so as to rotate the generator;
• and
• an idler shaft disposed parallel to the engine shaft and including a first intermediation gear engaged with the power generation driving gear and a second intermediation gear engaged with the power generation driven gear.
