PROBLEM TO BE SOLVED: To provide an axle driving device for a hybrid vehicle, which can combine simplification of a device constitution with downsizing thereof, and a motor unit that can achieve such axle driving device for a hybrid vehicle.SOLUTION: An axle driving device 1 comprises: a motor 8; an input shaft 3 to which power of an engine 120 from a CVT 121 side and power of the motor 8 from a front wheel output shaft 7 side can be input; rear wheel-side output shafts 6 and 6 which are driven by output of the input shaft 3 and output power to rear wheels; and a front wheel-side output shaft 7 which is driven by output of the motor 8 and outputs power to front wheels. The axle driving device 1 further comprises a first clutch 9 and a second clutch 10 which are arranged on the same axial center as that of the input shaft 3, at the CVT 121 side of the input shaft 3. The axle driving device performs/stops power transmission between the motor 8 and the input shaft 3 by engaging and disengaging the first clutch 9, and performs/stops power transmission between the motor 8 and the front wheel side output shaft 7 by engaging and disengaging the second clutch 10.SELECTED DRAWING: Figure 3
【課題】装置構成の簡素化と小型化を両立させることができるハイブリッド車両用車軸駆動装置を提供するとともに、また、このようなハイブリッド車両用車軸駆動装置を実現させるモータユニットを提供する。【解決手段】車軸駆動装置1は、モータ8と、CVT121側よりエンジン120の動力が、前輪側出力軸7側よりモータ8の動力が、入力可能とされる入力軸3と、入力軸3の出力により駆動され、後輪に対して動力を出力する後輪側出力軸6・6と、モータ8の出力により駆動され、前輪に対して動力を出力する前輪側出力軸7と、を備え、入力軸3のCVT121側にて入力軸3と同一軸心上に配置される第一クラッチ9及び第二クラッチ10を備え、第一クラッチ9の入切にて、モータ8と入力軸3との間の動力伝達を断接し、第二クラッチ10の入切にて、モータ8と前輪側出力軸7との間の動力伝達を断接する。【選択図】図3
