PROBLEM TO BE SOLVED: To adjust drive forces of left and right wheels by a simple and compact structure, and to improve motion performance by imparting the drive forces, related to a drive force adjustment device.SOLUTION: Either of two rotating shafts of a planetary gear mechanism 2 to which a boosting gear 4 is not connected, and a left axle 11 or a right axle 12 are connected to each other in a first gear row 5. The other is connected to either of two elements which is not connected to the first gear row 5 out of three elements of a differential case 16, the left axle 11 and the right axle 12 via a second gear row 6. A gear ratio of the planetary gear mechanism 2, the first gear row 5 and the second gear row 6 is a ratio at which the rotation of a motor 3 is stopped when there is no differential motion of a differential device 1, and set as a ratio at which the total torque of the left axle 11 and the right axle 12 is not changed at the impartment of the torque of the motor 3. A sun gear shaft 21 is arranged in a position which is offset to a vehicle fore-and-aft direction from the left axle 11 and the right axle 12. The motor 3 is arranged at one side in a vehicle width direction with the differential device 1 as a reference, and the planetary gear mechanism 2 is arranged at the other side.SELECTED DRAWING: Figure 1
【課題】駆動力調整装置に関し、簡素かつコンパクトな構造で左右輪の駆動力を調整するとともに、駆動力を付与することで運動性能を向上させる。【解決手段】遊星歯車機構2の回転軸のうち倍力ギヤ4が接続されていない二つのうちの一方と、左車軸11又は右車軸12とを第一ギヤ列5で接続する。他方は第二ギヤ列6を介してデフケース16,左車軸11,右車軸12の三要素のうち第一ギヤ列5に接続されていない二要素の一つと接続する。遊星歯車機構2,第一ギヤ列5,第二ギヤ列6のギヤ比は、デフ装置1の差動が無い時にモータ3の回転が停止する比率であって、モータ3のトルク付与時に左車軸11及び右車軸12の合計トルクが変化しない比率とする。サンギヤ軸21は、左車軸11及び右車軸12から車両前後方向にオフセットした位置に配置する。デフ装置1を基準として車幅方向の一側にモータ3を配置し、他側に遊星歯車機構2を配置する。【選択図】図1
