To provide a drive unit for a hybrid vehicle, which includes a planetary gear group and two motor generators and which can increase power transmission efficiency during running at high speed by enabling high-load driving from a low speed range.SOLUTION: A planetary gear group 14 includes at least four rotary members. Speed shafts of the respective rotary members are arranged on a common velocity diagram along a transverse axis in accordance with gear ratios. When the speed shafts are defined as a first member, a second member, a third member, and a fourth member in the order from an end along the horizontal axis, the first member 22 is connected to a first 1M/G60 and connectable to an input shaft 10, the second member 28, 34 is connected to an output shaft 12, the third member 24, 38 is fixable to a stationary portion 46 and connectable to the input shaft 10, and the fourth member 32 is connected to a second 2M/G62. The first member is configured by a first drive gear 29 connected to the first 1M/G60 and a second drive gear 22 connected to the input shaft 10.SELECTED DRAWING: Figure 1

    【課題】遊星歯車群と2個のモーター・ジェネレーターを備えたハイブリッド自動車用駆動装置において、低速域から高負荷駆動を可能にし、高速走行における動力伝達効率を高くすること。【解決手段】遊星歯車群14が少なくとも4個の回転メンバーを有し、共通速度線図上に各回転メンバーの速度軸を歯数比に応じて横軸に沿って並べ、端から順番に第1メンバー、第2メンバー、第3メンバー、第4メンバーとしたとき、第1メンバー22を第1M/G60と連結するとともに入力軸10と連結可能とし、第2メンバー28、34を出力軸12と連結し、第3メンバー24、38を静止部46に固定可能とするとともに入力軸10と連結可能とし、第4メンバー32を第2M/G62と連結し、第1メンバーを、第1M/G60と連結した第1駆動歯車29と、入力軸10と連結した第2駆動歯車22の、2つで構成した。【選択図】図1
