POWER TRANSMISSION SYSTEM FOR HYBRID VEHICLE

摘要

A power transmission system for a hybrid vehicle including an engine, a first planetary gearset and a second planetary gear set is provided. In particular, the first planetary gearset includes a plurality of first rotational elements, one of which is coupled with an output shaft of the engine and one of which is coupled with a first motor generator, and two of which are allowed to be directly selectively connected directly by a clutch. The second planetary gearset includes a plurality of second rotational elements, one of which is permanently coupled with one of the first rotational elements of the first planetary gearset, one of which is coupled with a second motor generator and one of which is connected directly with drive unit.
