Power train for hybrid vehicle

The present invention provides a power train for a hybrid vehicle that can achieve a fixed gear ratio mode where a vehicle is driven at a fixed gear ratio, such as shift stages of common transmission, only by the driving force of an engine without driving a motor generator, as well as an electric ve...

Beschreibung
Zusammenfassung:	The present invention provides a power train for a hybrid vehicle that can achieve a fixed gear ratio mode where a vehicle is driven at a fixed gear ratio, such as shift stages of common transmission, only by the driving force of an engine without driving a motor generator, as well as an electric vehicle mode and a hybrid mode that are basic driving modes of a hybrid vehicle, such that it is possible to drive the vehicle with high efficiency in accordance with traveling conditions of the vehicle and improve fuel efficiency. Further, according to the power train for a hybrid vehicle, the number of gear teeth of a sun gear and a pinion of a planetary gear set, which is a component, can be changed in various ways, such that it is possible to more freely select the capacity of a clutch or a motor generator. Therefore, it is possible to design a compact transmission.
