PROBLEM TO BE SOLVED: To provide a left and right drive force distribution unit with a disconnection mechanism for a four-wheel drive vehicle, with small size and weight and high lateral symmetry.SOLUTION: There are provided a central axle 60 which penetrates a ring gear 68 being cantilevered and is rotatably supported, being concentric with the ring gear 68, for outputting a drive force that is transmitted to the ring gear 68 to left and right sub drive wheels 16 L, 16R, a second clutch 62 which contains a movable sleeve 70 that is moved in axial direction, for connection/disconnection between the ring gear 68 and the central axle 60 according to movement position of the movable sleeve 70, and a second clutch actuator 72 which is positioned on the side opposite to the side where the ring gear 68 is supported, relative to an outer peripheral engagement tooth 68a of the ring gear 68, for moving the movable sleeve 70 between a connection position for connecting the ring gear 68 and the center axle 60, not for rotative rotation, and a disconnection position for allowing relative rotation between the ring gear 68 and the center axle 60.
【課題】形状および重量が小さく左右の対称性が高い4輪駆動車両のディスコネクト機構付左右駆動力配分ユニットを提供する。【解決手段】片持状に支持されたリングギヤ68を貫通し且つそのリングギヤ68と同心状態で回転可能に支持され、リングギヤ68に伝達された駆動力を左右の副駆動輪16L、16Rへ出力する中央車軸60と、軸線方向に移動させられる可動スリーブ70を有し、可動スリーブ70の移動位置に応じてリングギヤ68と中央車軸60との間を断接する第2クラッチ62と、リングギヤ68の外周係合歯68aに対してそのリングギヤ68が支持される側とは反対側に位置し、可動スリーブ70を、リングギヤ68と中央車軸60とを相対回転不能に連結するコネクト位置とリングギヤ68と中央車軸60との相対回転を許容するディスコネクト位置との間で移動させる第2クラッチアクチュエータ72とを、含む。【選択図】図3
