To provide a hybrid vehicle having improved suppression in power loss of a motor and travel stability.SOLUTION: A power transmission device includes a belt-type continuously variable transmission (CVT) 10, and a driving planetary gear mechanism 8 and a driven planetary gear mechanism 19 for directly transmitting power of a motor 3 to an output shaft 18. The driving planetary gear mechanism 8 includes a second clutch 35, and the driven planetary gear mechanism 19 includes a third clutch 40. Power of the driving planetary gear mechanism 8 is transmitted to the driven planetary gear mechanism 19 through an intermediate clutch 33. The power of the motor 3 is directly transmitted to the output shaft 18 without through the continuously variable transmission 10, and accordingly power loss of the motor 3 can be suppressed. By controlling clutches 25, 33, 35 and 40 and a brake 41, various travel control can be achieved.SELECTED DRAWING: Figure 1

    【課題】モータの動力損失抑制と走行安定性とが向上したハイブリッド車を提供する。【解決手段】動力伝達装置は、ベルト式の無段変速機(CVT)10と、モータ3の動力をアウトプット軸18に直接的に伝達できる主動遊星歯車機構8及び従動遊星歯車機構19を備えている。主動遊星歯車機構8は第2クラッチ35を備え、従動遊星歯車機構19は第3クラッチ40を備えている。主動遊星歯車機構8の動力は中間クラッチ33を介して従動遊星歯車機構19に伝達される。モータ3の動力が無段変速機10を経由せずにアウトプット軸18にダイレクトに伝わるため、モータ3の動力損失を抑制できる。クラッチ25,33,35,40とブレーキ41を制御することにより、多彩な走行制御を実現できる。【選択図】図1
