To provide a simply configured vehicle drive apparatus that is improved to be incorporated in a vehicle.SOLUTION: A vehicle drive apparatus 10 disclosed includes: left and right motor housings 11, 12 that constitute outer shrouds of motors 1, 2; a gear-box housing 13 that houses a gar box 3 for amplifying torque of the motors 1,2 and transmitting the torque to left and right wheels, is disposed between the motor housings 11, 12, and is arranged offset downward with respect to the motor housings 11, 12; an inverter case 14 that houses a pair of semiconductor modules 6,7 for converting DC power into AC power and supplying the motor 1,2 with the converted power and a circular ferrite core 17 into which a bus bar 20 for supplying the semiconductor modules 6, 7 with power is inserted, and is arranged in a concave portion 8 that is surrounded by the motor housings 11, 12 and gear-box housing 13; and a PN wire 9 that is connected to a lower surface side of the inverter case 14. The ferrite core 17 is arranged underneath the semiconductor modules 6, 7.SELECTED DRAWING: Figure 1

    【課題】車両駆動装置に関し、簡素な構成で車両搭載性を改善する。【解決手段】開示の車両駆動装置10は、モータ1,2の外装をなす左右のモータハウジング11,12と、モータ1,2のトルクを増幅して左右輪に伝達するギヤボックス3を内蔵し、モータハウジング11,12の間に挟装されるとともに、モータハウジング11,12に対して下方にオフセットして配置されるギヤボックスハウジング13と、直流電力を交流電力に変換してモータ1,2に給電する一対の半導体モジュール6,7と半導体モジュール6,7に電力を供給するバスバー20が挿通される環状のフェライトコア17とを内蔵し、モータハウジング11,12とギヤボックスハウジング13とで囲まれた凹部8に配置されるインバータケース14と、インバータケース14の下面側に接続されるPN線9とを備える。フェライトコア17は、半導体モジュール6,7の下方に配置される。【選択図】図1
