Abstract
A transmission system of a hybrid electric vehicle may include first and second motors/generators, a planetary gear set, a first output gear for the second motor/generator, a second output gear for an engine, an under drive first clutch, and an over drive second clutch, disposed on or coupled to an input shaft. A hollow shaft is configured at an outer circumference side of the input shaft to transmit accelerated power of the engine or power of the first motor/generator to the second output gear and an outer shaft at an outer circumference side of the hollow shaft to transmit power of the second motor/generator to the first output gear. The first and second clutches are adjacently disposed at an engine side on the input shaft, and selectively transmit each of rotational power of the input shaft and rotational power of the hollow shaft to the second output gear.
