    摘要: A power transmission apparatus includes a first input shaft selectively receiving an input torque, a second input shaft coaxially disposed with the first input shaft and selectively receiving the input torque, first and second intermediate shafts selectively interconnected and disposed in parallel with the first input shaft, a torque mediating shaft coaxially disposed with the first input shaft, a preliminary shifting section receiving a torque through a first input shaft and selectively outputting a shifted torque to the second intermediate shaft, a compound shifting section including a planetary gear set having a sun gear fixedly connected with the torque mediating shaft, a planet carrier fixedly connected with the second input shaft, and a ring gear externally gear-meshed with the second intermediate shaft, and an output shaft receiving a torque received from the compound shifting section and transmitting the received torque to a differential.

    摘要: A power transmission apparatus of a hybrid electric vehicle using an engine and first and second motor/generators as power sources, may include a first shaft, a second shaft which is selectively connectable to the first shaft and fixedly connected to the first motor/generator, a third shaft selectively connectable to the first shaft, a fourth shaft coaxially mounted with the third shaft, a fifth shaft transferring rotational power transmitted from the third and fourth shafts to a final reduction gear, a sixth shaft fixedly connected to the second motor/generator, a seventh shaft transferring rotational power transmitted from the sixth shaft to the final reduction gear and a planetary gear set including first, second, and third rotation elements wherein the first to seventh shafts are externally gear-meshed with each other by four gear sets so that rotational power is transmitted.
