The invention relates to a power transmission apparatus for a hybrid electric vehicle which includes: a planetary gear set including first, second and third rotary elements; a first shaft fixedly connected to an output shaft of an engine; a second shaft fixedly connected to the first rotary element and a first motor/generator; a third shaft receiving rotational power from the first shaft; a fourthshaft selectively connected with the first shaft, and the fourth shaft selectively receiving rotational power from the first shaft or from the third rotary element; a fifth shaft fixedly connected toa second motor/generator; and a sixth shaft transmitting rotational power transmitted from the fifth shaft to a final reduction gear of the differential gear. In particular, the six shafts are connected to external gears mutually by four gear sets so that rotational power is transmitted.

    本发明涉及混合动力电动车辆的动力传递装置。该装置包括:行星齿轮组、第一轴、第二轴、第三轴、第四轴、第五轴以及第六轴,所述行星齿轮组包括第一旋转元件、第二旋转元件和第三旋转元件;所述第一轴固定地连接至发动机的输出轴;所述第二轴固定地连接至第一旋转元件和第一电动机/发电机;所述第三轴从第一轴接收旋转动力;所述第四轴选择性地与第一轴连接,并且所述第四轴选择性地接收来自第一轴的旋转动力或者接收来自第三旋转元件的旋转动力;所述第五轴固定地连接至第二电动机/发电机;所述第六轴将从第五轴传递的旋转动力传递至差速器的最终减速齿轮。特别地,六个轴通过四个齿轮组连接为相互外齿轮接合,从而传递旋转动力。
